Core Concepts of HP BladeSystem Architecture

The fundamental principle behind the HP BladeSystem architecture is consolidation. By integrating servers, storage, networking, power, and management into a single chassis or enclosure, it drastically reduces the physical footprint required in a data center. This high-density design allows organizations to deploy more computing power in less rack space compared to traditional rack-mount servers. The reduction in physical space also leads to lower operational costs related to power, cooling, and data center real estate. The HP0-S20 Exam requires a clear understanding of these consolidation benefits. Another core concept is the simplification of infrastructure management. The BladeSystem architecture centralizes management tasks through a unified interface. Instead of managing each server individually, administrators can manage the entire enclosure and all its components from a single point of control. This includes tasks such as firmware updates, power management, and health monitoring. This centralized approach reduces administrative overhead, minimizes the potential for human error, and allows IT teams to respond more quickly to changing business needs. This efficiency is a key selling point of the platform. Reduced cabling is a third and highly visible benefit of the architecture. In a traditional server rack, each server requires its own power cords, network cables, and storage connections, leading to a complex and difficult-to-manage web of wires. The BladeSystem design abstracts these connections through a shared midplane within the enclosure. Server blades connect directly to this midplane, which then routes power, network, and storage traffic to shared modules. This elegant design dramatically cuts down on cabling, simplifying deployment, improving airflow for better cooling, and making troubleshooting significantly easier.

Introduction to the c-Class Enclosure

The c-Class enclosure is the physical foundation of the HP BladeSystem. It is a chassis that provides the housing, power, cooling, connectivity, and management for all the components within it. Available in different form factors, such as the c7000 (10U) and c3000 (6U), the enclosure is designed to fit into standard data center racks. The HP0-S20 Exam will test your knowledge of the physical layout and capabilities of these enclosures. Understanding the structure is the first step toward mastering the technology, as everything else builds upon this core component. At the heart of the enclosure is the active midplane. This is not a simple backplane but an intelligent, high-speed printed circuit board that connects the server blades to the interconnect modules, power supplies, and fans without any internal cables. It provides dedicated high-bandwidth pathways for network and storage traffic, ensuring reliable and high-performance communication between components. The design of the midplane is crucial for the system's overall performance and scalability, allowing for the easy addition or replacement of components while the system is running. The enclosure is divided into several bays and slots. The front is dedicated to server blades, which can be half-height or full-height models. The rear of the enclosure houses the interconnect bays for network and storage modules, power supply bays, and fan bays. It also features a dedicated slot for the Onboard Administrator management module. This modular design provides immense flexibility, allowing organizations to configure the enclosure with the specific mix of computing, networking, and storage components that best suits their workload requirements.

Exploring Server Blade Components

HP ProLiant server blades are the compute engines within the BladeSystem enclosure. These are compact, self-contained servers that slide into the front bays of the chassis. Each blade contains processors, memory, local storage options, and management controllers. They draw power and connect to the network and storage infrastructure through the enclosure's midplane. A key topic in the HP0-S20 Exam is identifying the different types of server blades and understanding their features, such as processor families supported, maximum memory capacity, and available mezzanine card slots for expansion. Mezzanine cards are an essential component for expanding the I/O capabilities of a server blade. Because of their compact form factor, server blades do not have standard PCIe slots like rack servers. Instead, they use mezzanine cards to add connectivity options such as Fibre Channel Host Bus Adapters (HBAs) for connecting to a Storage Area Network (SAN), or additional network interface controllers (NICs) for increased network bandwidth or connectivity to different networks. Understanding which cards are compatible with which server blades and interconnect modules is a critical area of knowledge. Each server blade also includes an integrated Lights-Out (iLO) management processor. The iLO is a powerful tool that provides remote management capabilities for the server, independent of the main operating system. Administrators can use iLO to power the server on or off, view a remote console, mount virtual media, and monitor the health of the hardware. This out-of-band management is fundamental to the BladeSystem's operational efficiency, allowing for complete control over the compute resources from anywhere on the network. The HP0-S20 Exam will expect you to be familiar with the core functions of iLO.

Understanding Onboard Administrator (OA)

The Onboard Administrator, or OA, is the central nervous system of the HP BladeSystem c-Class enclosure. It is a dedicated management module that resides in a specific slot in the rear of the chassis. The OA provides a single point of management for the entire enclosure, including all installed server blades, interconnects, power supplies, and fans. From the moment the enclosure is powered on, the OA takes control, enabling initial setup and ongoing administration. Its role is so critical that enclosures are often configured with a second, redundant OA module for high availability. Through its web-based graphical user interface (GUI) or a command-line interface (CLI), administrators can perform a vast array of management tasks. This includes configuring the enclosure settings, monitoring the health and status of all components, managing user accounts and access permissions, and generating reports. The OA provides a holistic view of the entire system, displaying power consumption, thermal data, and any hardware alerts in a centralized dashboard. This simplifies troubleshooting and proactive maintenance, which are key skills tested in the HP0-S20 Exam. One of the most powerful features managed by the OA is the initial setup wizard. When a new enclosure is powered on for the first time, the OA guides the administrator through the process of configuring essential parameters, such as the enclosure name, IP addresses, and user credentials. It also helps in discovering and identifying all the installed components. This guided setup process greatly simplifies the deployment of a BladeSystem, reducing the time and potential for errors associated with manual configuration. A solid grasp of the OA's capabilities is non-negotiable for anyone preparing for this certification.

The Role of Virtual Connect in BladeSystem

HP Virtual Connect is a groundbreaking technology that simplifies and abstracts the network connections for server blades. It is implemented through interconnect modules that sit in the rear of the c-Class enclosure. The core idea behind Virtual Connect is to decouple the server's network identity, defined by MAC addresses and World Wide Names (WWNs), from the physical server hardware. This allows administrators to pre-configure network connections for server bays, rather than for the individual servers themselves. This abstraction is a major focus of the HP0-S20 Exam. With Virtual Connect, a server's network profile, which includes LAN and SAN connection definitions, is associated with a server bay in the enclosure. If a physical server blade needs to be replaced, the new blade automatically inherits the exact same network profile of the bay it is inserted into. This means the change is completely transparent to the upstream network and storage switches. There is no need for network or storage administrators to reconfigure switch ports or zoning, a process that is traditionally time-consuming and prone to error. This technology dramatically improves operational efficiency and server lifecycle management. It enables stateless computing, where server hardware is treated as a generic resource pool. Administrators can add, replace, or upgrade servers with minimal disruption and without involving other IT teams. Virtual Connect modules, such as Virtual Connect FlexFabric, can handle Ethernet, Fibre Channel, and Fibre Channel over Ethernet (FCoE) traffic, further simplifying the I/O infrastructure. Understanding how to define server profiles and manage connections through the Virtual Connect Manager is essential for exam success.

Power and Cooling Subsystems

The power subsystem of the HP BladeSystem is designed for high efficiency and redundancy. The c-Class enclosure uses a pooled power infrastructure, where multiple hot-pluggable power supplies feed into a common power backplane. This allows the total power capacity to be shared among all components in the enclosure. This design is far more efficient than having individual power supplies for each server, as it allows the power supplies to operate closer to their peak efficiency range. The HP0-S20 Exam covers concepts like power redundancy modes and capacity planning. HP offers different power supply options with varying efficiency ratings, such as Platinum and Titanium, allowing organizations to choose the best option based on their power and budget requirements. The Onboard Administrator actively manages the power infrastructure. It monitors power consumption in real-time and can enforce power caps on servers or the entire enclosure to prevent overloading the data center circuits. Administrators can configure redundancy modes, such as N+N or N+1, to ensure that the failure of one or more power supplies does not lead to a system outage. The cooling system is equally robust and intelligent. A bank of high-efficiency, hot-pluggable fans in the rear of the enclosure pulls air from front to back, cooling the server blades and interconnect modules. The speed of these fans is dynamically controlled by the Onboard Administrator based on the thermal sensors located throughout the chassis. This adaptive cooling ensures that components are kept within their optimal operating temperatures while minimizing power consumption and acoustic noise. Understanding how the system manages its thermal envelope is a key aspect of BladeSystem knowledge.

Initial Preparation Strategy for the HP0-S20 Exam

A successful journey to passing the HP0-S20 Exam begins with a well-structured preparation strategy. The first step is to thoroughly review the official exam objectives provided by HP. These objectives are a blueprint of the exam, detailing all the topics and sub-topics that will be covered. By understanding what is expected, you can focus your study efforts on the most relevant areas and avoid wasting time on information that is not pertinent to the certification. This targeted approach is the most efficient way to prepare. Once you are familiar with the objectives, gathering the right study materials is the next critical step. This should include official HP documentation, such as user guides, configuration manuals, and white papers related to the c-Class BladeSystem. These resources provide the most accurate and in-depth information. Supplementing these official documents with high-quality training courses, either instructor-led or online, can provide structured learning paths and expert insights. It is important to use a variety of resources to gain a comprehensive understanding of the material. Finally, practical experience is invaluable. If possible, get hands-on access to an HP BladeSystem environment. Working with the hardware, navigating the Onboard Administrator and Virtual Connect Manager interfaces, and performing basic configuration and troubleshooting tasks will solidify the theoretical knowledge you have gained. If physical access is not possible, look for online labs or simulators. Combining theoretical study with practical application is the most effective method for building the confidence and competence needed to pass the HP0-S20 Exam.

Navigating the Onboard Administrator Interface

The Onboard Administrator (OA) is the primary management tool for the entire BladeSystem enclosure, and proficiency with its interface is critical for the HP0-S20 Exam. The most common way to interact with the OA is through its web-based graphical user interface (GUI). After logging in, you are presented with a system status overview that provides a high-level summary of the health of the enclosure and its components. This dashboard view uses color codes, such as green for normal and amber or red for warnings and critical errors, to give administrators a quick visual assessment. The GUI is logically structured with a navigation pane on the left side. This pane is organized into categories that correspond to the physical and logical components of the system. These include sections for Enclosure Settings, Active Onboard Administrator, Server Blades, Interconnect Bays, Power and Thermal, and User Administration. Clicking on any of these categories expands a tree of options, allowing you to drill down into specific details and configuration screens. For instance, under Server Blades, you can select an individual blade to view its status, power it on or off, and launch its iLO remote console. Beyond the GUI, the OA also offers a powerful Command Line Interface (CLI). The CLI is accessible via SSH or a direct serial connection and is favored by many experienced administrators for its speed and scriptability. It provides access to all the same functions as the GUI. The HP0-S20 Exam may include questions that test your knowledge of key CLI commands for tasks like checking system health, configuring network settings, or managing user accounts. Familiarity with both the GUI and the basic structure of the CLI is essential for comprehensive management and exam readiness.

Advanced Configuration of Server Blades

Managing server blades extends beyond simple power on and off operations. The Onboard Administrator provides several advanced configuration options that are important for the HP0-S20 Exam. One such feature is the ability to configure server boot options directly from the OA. You can set the one-time boot order for a server blade, forcing it to boot from a specific device like a USB key, a virtual media image mounted via iLO, or a PXE network server. This is extremely useful for performing operating system installations, diagnostics, or recovery tasks without needing to physically access the server. Another key aspect is the management of server profiles within the Virtual Connect environment, although primarily handled by Virtual Connect Manager, the OA provides the initial linking. However, the management of server-specific BIOS or UEFI settings via iLO is a crucial skill. Through the iLO remote console, you can access the server’s startup environment to configure a wide array of parameters, including processor settings, memory options, and integrated device configurations. Being able to navigate these settings is vital for optimizing server performance and ensuring compatibility with the intended workload. Furthermore, the OA provides tools for asset management. You can assign specific information to each server bay, such as an asset tag, the server's role, and its owner. This metadata is stored within the OA and helps in tracking and managing the hardware assets within the data center. The ability to clearly label and document the purpose of each server blade within the enclosure is a best practice for maintaining a well-organized and efficient infrastructure. These seemingly minor administrative features contribute to overall manageability and are relevant topics for a system administrator.

Managing User Accounts and Security

Security is a paramount concern in any data center environment, and the HP BladeSystem provides robust mechanisms for controlling access. The Onboard Administrator is the central point for user authentication and authorization. You can create local user accounts directly on the OA module, assigning each user a specific privilege level. These levels range from a read-only Operator, who can only view system status, to a full Administrator, who has complete control over the enclosure and all its components. Understanding these different privilege levels and when to apply them is a key security concept for the HP0-S20 Exam. For larger organizations, managing local user accounts on every device is not scalable. To address this, the OA supports integration with directory services such as LDAP and Active Directory. By configuring directory integration, you can centralize user management and allow users to log in to the OA using their standard corporate credentials. This simplifies administration, enforces consistent password policies, and provides a single point for revoking access when an employee leaves the organization. The process of configuring these directory settings is a common administrative task. In addition to user access control, the OA includes other security features. You can configure network settings to restrict access to the management interface, set up secure protocols like SSH and HTTPS, and manage SSL certificates to ensure encrypted communication. The OA also maintains detailed logs of all user activity and system events, which is crucial for security auditing and troubleshooting. A comprehensive understanding of how to secure the BladeSystem management plane is essential for both real-world deployment and for success on the HP0-S20 Exam.

Firmware Management and Update Strategies

Firmware is the low-level software that controls the operation of hardware components. In a BladeSystem, this includes firmware for the Onboard Administrator, server blade BIOS/UEFI, iLO, interconnect modules, and other devices. Keeping firmware up-to-date is critical for ensuring system stability, enabling new features, and patching security vulnerabilities. The HP0-S20 Exam requires a thorough understanding of the tools and best practices for managing firmware across the entire BladeSystem ecosystem. A disorganized approach to firmware can lead to instability and compatibility issues. HP provides several tools to simplify the firmware update process. The most comprehensive of these is the Service Pack for ProLiant (SPP). The SPP is a single, pre-tested ISO image that contains a consolidated set of firmware, drivers, and system software for all supported components. Using the HP Smart Update Manager (HP SUM) tool, which is included in the SPP, administrators can inventory the current firmware versions in an enclosure and deploy updates in a controlled manner. HP SUM can perform updates online while the operating system is running or offline in a maintenance mode. A crucial aspect of firmware management is understanding dependencies. Often, the firmware for different components must be at compatible levels to function correctly. For example, a new feature in a Virtual Connect module's firmware might require a specific iLO firmware version on the server blades. The SPP helps manage these dependencies by testing and releasing all components as a single validated bundle. For the HP0-S20 Exam, you should be familiar with the concept of a firmware baseline, the purpose of the SPP, and the general workflow for using HP SUM to perform updates.

Implementing Virtual Connect for Network and Storage

Virtual Connect (VC) is one of the most powerful and transformative technologies in the BladeSystem portfolio, and it is a major focus of the HP0-S20 Exam. The implementation process begins with the initial setup of the Virtual Connect domain, which is a logical grouping of one or more enclosures managed by a single pair of primary and redundant Virtual Connect modules. The Virtual Connect Manager (VCM) is the management interface, accessible via the OA, used to configure and manage this domain. The first step is to define the domain and configure its network settings. Once the domain is established, the next step is to configure the networks and fabrics. In VCM, you create Shared Uplink Sets for Ethernet networks and define SAN Fabrics for Fibre Channel connections. A Shared Uplink Set groups multiple external network ports (uplinks) together for redundancy and load balancing. You then define individual networks (VLANs) that will be mapped to these uplink sets. This process allows you to abstract the physical network infrastructure from the servers, providing a flexible pool of network connectivity. The final and most important step is creating Server Profiles. A Server Profile is a template that contains all the I/O configuration for a server, including MAC addresses for its network adapters and WWNs for its storage adapters. It also defines which networks and SAN fabrics each adapter should connect to. This profile is not tied to a physical server but to a server bay. This means any server placed in that bay will automatically receive that exact I/O identity. This concept of stateless computing is fundamental to Virtual Connect's value proposition.

Configuring FlexFabric and Virtual Connect Flex-10

The HP FlexFabric portfolio represents the evolution of converged networking, and understanding it is key for the HP0-S20 Exam. A Virtual Connect FlexFabric module is a single interconnect that can handle multiple traffic types, including Ethernet, Fibre Channel over Ethernet (FCoE), and iSCSI. This convergence simplifies the physical infrastructure by reducing the number of required interconnect modules and cables. Instead of separate modules for LAN and SAN, a single pair of FlexFabric modules can provide connectivity for all I/O needs, lowering costs and complexity. A core technology within this ecosystem is Flex-10. Flex-10 allows a single 10 Gigabit Ethernet physical port on a server blade's network adapter to be divided into multiple, smaller virtual network interfaces called FlexNICs. Each FlexNIC appears to the operating system as a distinct physical NIC. The administrator can define up to four FlexNICs per physical port and can set the bandwidth for each one in increments, from 100 Mbps up to 10 Gbps. This provides an unprecedented level of flexibility for carving up network bandwidth to match the specific needs of different applications or virtual machines running on the server. When configuring FlexFabric modules, you use the Virtual Connect Manager to define the connections. You can configure some uplinks for standard Ethernet traffic and others for converged FCoE traffic that carries both network and storage data to an upstream switch. On the server side, within the Server Profile, you define whether a specific adapter port will function as an Ethernet FlexNIC or a Fibre Channel/FCoE FlexHBA. This ability to dynamically assign I/O functions to physical hardware is a hallmark of the FlexFabric architecture and a powerful tool for building agile data center infrastructure.

Monitoring System Health and Performance

Proactive monitoring is essential for maintaining a healthy and stable BladeSystem environment. The Onboard Administrator serves as the central hub for health and status information. Its main dashboard provides an at-a-glance view of the entire system, immediately highlighting any components that are in a degraded or failed state. For more detailed information, you can navigate to the specific component's status page. For example, the Power and Thermal page displays real-time data on power consumption, power supply status, and temperature readings from sensors throughout the enclosure. The OA also maintains a comprehensive System Log. This log records every event that occurs within the enclosure, from routine user logins to critical hardware alerts. Reviewing this log is a fundamental step in any troubleshooting process. You can filter the log by severity or component to quickly isolate relevant events. The Integrated Management Log (IML) on each server blade, accessible via iLO, provides a similar event log specific to that server's hardware. Understanding how to read and interpret these logs is a skill tested in the HP0-S20 Exam. For performance monitoring, the tools become more granular. While the OA provides high-level power and thermal data, more detailed performance metrics for servers, such as CPU utilization, memory usage, and network throughput, are typically monitored through the operating system or through higher-level management tools like HP OneView. However, the Virtual Connect Manager does provide statistics for its network ports, showing data rates and error counts, which can be useful for diagnosing network performance issues. A complete monitoring strategy involves using all these tools in concert.

Troubleshooting Common BladeSystem Issues

Despite its robust design, issues can still arise in a BladeSystem environment. A systematic approach to troubleshooting is a critical skill for any administrator and is an important topic for the HP0-S20 Exam. A common category of problems relates to hardware failures. This could be a failed fan, a faulty power supply, or a problem with a server blade. The first step is always to check the health status in the Onboard Administrator. The OA will pinpoint the exact component that has failed and provide details in its logs. Thanks to the system's hot-pluggable design, most failed components can be replaced without powering down the enclosure. Connectivity issues are another frequent challenge. A server blade may be unable to communicate with the network or access its storage. Troubleshooting this begins with verifying the server's status in the OA and checking for any physical link lights on the interconnect modules. The next step is to examine the server's profile in Virtual Connect Manager. You should confirm that the correct networks or SAN fabrics are assigned to the server's adapters and that the upstream connections (uplinks) are active and healthy. Mismatched VLAN tags or incorrect SAN zoning are common culprits. Firmware and configuration problems can be more subtle. An issue might appear after a firmware update or a configuration change. In these cases, reviewing the OA and iLO event logs for any errors that occurred around the time of the change is crucial. One powerful troubleshooting tool provided by the OA is the ability to generate a "show all" support dump. This single command collects a comprehensive set of configuration information, logs, and status reports from all components in the enclosure, which can be invaluable for detailed analysis or for sharing with technical support.

Scripting and Automation with HP BladeSystem

For managing BladeSystem environments at scale, automation is key. The Onboard Administrator's Command Line Interface (CLI) is the foundation for scripting and automation. Every task that can be performed through the GUI can also be accomplished using CLI commands. Administrators can write simple scripts to automate repetitive tasks, such as checking the health status of multiple enclosures, changing user passwords, or performing a coordinated shutdown. Using SSH keys for authentication allows these scripts to run securely without needing to embed passwords. The scripting capabilities extend to the Virtual Connect Manager as well. The VCM CLI allows for the automation of network and storage provisioning. For example, you could write a script that creates a new Server Profile based on a template, assigns it to a specific bay, and powers on the server. This can dramatically accelerate the process of deploying new servers, reducing a task that could take hours to just a few minutes. This level of automation is essential in dynamic cloud and virtualized environments where resources need to be provisioned on demand. While not a direct objective of the HP0-S20 Exam, which focuses on the fundamentals, understanding the potential for automation is important for a well-rounded administrator. For more advanced automation, HP provides tools like the HP Scripting Tools for Windows PowerShell. These tools provide a set of PowerShell cmdlets that allow administrators to manage and configure BladeSystem and ProLiant servers using a powerful and widely adopted scripting language. This enables deep integration into larger data center automation workflows, showcasing the platform's enterprise readiness.

Key Management Tasks for the HP0-S20 Exam

To succeed in the HP0-S20 Exam, you must be confident in your ability to perform a core set of management tasks. First and foremost is the initial setup and configuration of a new enclosure using the Onboard Administrator's first-time setup wizard. This includes assigning IP addresses, creating an administrator account, and verifying that all components are discovered correctly. This foundational task is the starting point for all other management activities. You should be familiar with every step of this wizard-driven process. Another key area is managing the server lifecycle. This involves powering server blades on and off, accessing their remote console via iLO, and mounting virtual media to install an operating system. It also includes the critical task of managing server profiles in a Virtual Connect environment. You should be able to create, edit, and assign server profiles, understanding how this process affects the server's network and storage identity. This is one of the most tested concepts related to BladeSystem management. Finally, routine monitoring and maintenance are crucial. You must be able to navigate the OA and VCM interfaces to check the health status of all hardware components. This includes interpreting status indicators and reading system logs to identify potential issues. Furthermore, you should understand the process of updating firmware using the Service Pack for ProLiant (SPP) and HP Smart Update Manager (HP SUM). Mastering these essential, day-to-day administrative tasks will provide you with the practical knowledge needed to confidently answer the scenario-based questions on the HP0-S20 Exam.

Fundamentals of BladeSystem Networking

Networking within an HP BladeSystem is fundamentally different from traditional rack server environments. The key difference, which is a major topic for the HP0-S20 Exam, is the use of an enclosure midplane and interconnect modules. Instead of each server having multiple network cables running to top-of-rack switches, each server blade has high-speed connections to the midplane. These connections are then routed to interconnect bays in the rear of the enclosure. The modules placed in these bays determine the type and capability of the external network connectivity. This architecture provides significant benefits. The most obvious is the drastic reduction in cabling, which simplifies installation and maintenance while improving airflow and cooling efficiency. It also offers immense flexibility. By simply changing the interconnect modules in the rear of the enclosure, you can completely alter the networking capabilities of all the servers without ever having to touch the servers themselves. You could switch from simple 1Gb Ethernet to 10Gb Ethernet, or even to a converged 40Gb fabric, just by swapping modules. The server-side networking components are also integrated. Each server blade comes with embedded network controllers, known as LOMs (LAN on Motherboard). For additional bandwidth or different types of connectivity, mezzanine cards can be installed. The signals from both the LOMs and the mezzanine cards are mapped to specific interconnect bays. A critical concept for the HP0-S20 Exam is understanding this mapping. For example, the first embedded NIC on a server blade (LOM1) will always map to interconnect bays 1 and 2, ensuring a predictable and consistent connectivity path.

Configuring Ethernet Pass-Thru Modules

The simplest type of network interconnect for the BladeSystem is the Ethernet Pass-Thru module. As its name implies, this module does not perform any switching. It simply provides a direct, one-to-one connection, or "pass-thru," from each server blade's network port to an external network port on the module. For every server blade in the enclosure, there is a corresponding external RJ-45 or SFP+ port on the front of the Pass-Thru module. This makes the BladeSystem behave very much like a collection of individual rack servers from a networking perspective. Configuration of a Pass-Thru module is minimal, as it has no management interface or switching intelligence. It is essentially a passive device. The primary reason an organization might choose a Pass-Thru module is to maintain an existing network management model. If a company has standardized on a specific brand of top-of-rack switch and wants to use all of its advanced features for managing server ports, the Pass-Thru module allows them to do so. Each server port appears as a direct connection to the external switch, which then handles all VLAN tagging, security policies, and traffic management. While simple, it's important for HP0-S20 Exam candidates to understand the trade-offs of this approach. The major disadvantage of using Pass-Thru modules is the loss of the abstraction and simplification benefits offered by technologies like Virtual Connect. Cabling complexity is increased, as you need a separate cable for each server network port you want to use. Furthermore, if you replace a server blade, the network team may need to reconfigure the port on the external switch, which reintroduces the manual processes that other solutions aim to eliminate.

Mastering Virtual Connect Ethernet Modules

Virtual Connect (VC) Ethernet modules are intelligent, Layer 2 switching modules that represent a significant step up from Pass-Thru devices. They are the cornerstone of the network abstraction capabilities of the BladeSystem and a critical topic for the HP0-S20 Exam. These modules act as a network aggregation switch at the edge of the BladeSystem enclosure. They consolidate all the network traffic from the server blades within the enclosure and connect to the upstream data center network through a smaller number of uplink ports. The management of these modules is done through the Virtual Connect Manager (VCM). Within VCM, an administrator defines the entire network topology for the servers. This includes creating networks (which correspond to VLANs on the external network) and grouping uplink ports into Shared Uplink Sets for redundancy and load balancing. This configuration is done once for the entire enclosure. The key benefit is that the upstream network switches see the entire BladeSystem enclosure as a single, large switch, not as a collection of individual servers. This approach simplifies network management immensely. The core network team only needs to provide a set of trunked VLANs to the uplinks of the Virtual Connect modules. All the server-side port assignments and VLAN tagging are handled within VCM by the server administrator. This separation of duties empowers the server team to manage their own connectivity without needing to constantly file change requests with the network team. It also enables the stateless computing model, where server hardware can be replaced without any changes to the network configuration.

Understanding Server-Side Network Configuration

Regardless of the interconnect module used, the network adapters in the server blades must be configured correctly within the operating system. For the HP0-S20 Exam, you should understand how the server's view of the network is affected by the underlying BladeSystem technology. When using Pass-Thru modules, the configuration is straightforward. Each physical network port on the server blade appears as a standard NIC in the OS, and it must be configured with an IP address and other network settings just like any other server. When Virtual Connect is used, the configuration is more sophisticated. Technologies like Flex-10 allow a single physical 10Gb port to be presented to the OS as up to four separate virtual NICs (FlexNICs). Each FlexNIC has its own unique MAC address, assigned by Virtual Connect, and functions as an independent network interface. The administrator can then assign different FlexNICs to different purposes, such as one for management traffic, one for application traffic, and one for storage traffic like iSCSI, each with its own guaranteed bandwidth. The drivers for the network adapters are crucial for enabling these advanced features. The correct HP drivers must be installed in the guest operating system to recognize and properly utilize the FlexNICs. Without the appropriate drivers, the OS may only see a single physical device or may not be able to take advantage of the bandwidth management capabilities. Therefore, a complete server build process in a BladeSystem environment includes installing the OS, followed by the installation and configuration of the latest Service Pack for ProLiant (SPP) to ensure all necessary drivers are present.

Integrating with Cisco Fabric Extenders (FEX)

For organizations that have heavily invested in a Cisco network infrastructure, HP offers a unique interconnect option: the Cisco Fabric Extender (FEX) for HP BladeSystem. This module is not a switch itself, but rather a remote line card for an upstream Cisco Nexus parent switch. It allows the BladeSystem enclosure to become a native extension of the Cisco network fabric. This is an important integration topic that may be covered in the HP0-S20 Exam. From a management perspective, the FEX module is managed entirely by the parent Cisco Nexus switch. There is no separate management interface like Virtual Connect Manager. All the server-facing ports on the FEX appear as standard interfaces on the Nexus switch. This allows network administrators to use their existing Cisco tools and expertise to manage server connectivity. They can apply the same policies, QoS settings, and security rules to the server blade ports as they do to any other port in their network, providing a consistent operational model. The primary benefit of the FEX solution is seamless integration and unified management for Cisco-centric data centers. It extends the Cisco fabric directly to the server, collapsing the access and aggregation layers of the network. However, it's important to understand the trade-offs. The FEX model ties the BladeSystem's network management directly to the Cisco network team. It does not provide the server-centric abstraction and stateless computing benefits of Virtual Connect, as the network identity is still tied to the physical server port rather than the server bay.

Storage Connectivity Options: An Overview

Just as with networking, the BladeSystem architecture provides a flexible and integrated approach to storage connectivity. The goal is to connect server blades to centralized storage systems, such as a Storage Area Network (SAN) or Network Attached Storage (NAS). The HP0-S20 Exam will expect you to be familiar with the primary storage protocols and the hardware used to enable them within the BladeSystem. The choice of connectivity depends on the organization's existing infrastructure and performance requirements. The most common protocol for high-performance block storage is Fibre Channel (FC). To connect to an FC SAN, server blades must be equipped with a Fibre Channel Host Bus Adapter (HBA), which is installed as a mezzanine card. The HBAs connect through the midplane to Fibre Channel interconnect modules in the rear of the enclosure. These modules can be simple Pass-Thru devices or intelligent Virtual Connect Fibre Channel modules that provide WWN virtualization and simplified management. Other popular storage protocols include iSCSI and Fibre Channel over Ethernet (FCoE). Both of these protocols run over standard Ethernet networks, which allows for the convergence of storage and network traffic onto a single infrastructure. To use these protocols, you need standard or converged network adapters (CNAs) in the servers and compatible Ethernet or FlexFabric interconnect modules. Finally, for less demanding applications or specific use cases like boot-from-SAN, direct-attached storage (DAS) using local disks within the server blade is also a viable option.
