5 Introduction Hitachi Compute Blade 2500 is an enterprise-class blade server platform that extends the benefits of high-performance, high-density blade computing and virtualization to new areas of the data center (see Figure 1). This section describes how CB 2500 overcomes the constraints of previous-generation blade systems to deliver new capabilities and opportunities in an enterprise. Subsequent sections provide additional details about key features and functionality. Figure 1. Powered by Intel Xeon processors, Hitachi Compute Blade 2500 packs up to 240 Intel E7 cores into a fully loaded system. System Overview Hitachi Compute Blade 2500 with logical partitioning combines the benefits of virtualization with all the advantages of the blade server format: simplicity, flexibility, high compute density and power efficiency. It helps organizations to consolidate more resources, extend the benefits of virtualization solutions (VMware, Microsoft Hyper-V and so forth) to more areas of the enterprise data center, and cut costs without sacrificing performance. By choosing to power all the system's compute blade modules with Intel Xeon series processors and radically increasing the I/O performance and memory capacity, Hitachi has made it possible to use virtualization to consolidate application and database servers for backbone systems. These are areas where effective consolidation was difficult in the past. And, by removing performance and I/O bottlenecks, CB 2500 with logical partitioning reduces the administrative burden in the data center and opens up new opportunities for increasing efficiency and utilization rates. 4

6 The "hybrid I/O" capabilities of CB 2500 allow each blade to access a common shared switch network across all the blades while also allowing each blade to support unique I/O interfaces. This means you can standardize the switch interfaces across all blades, accommodate application-specific I/O interfaces per blade, or both, using the same system. To enable this I/O versatility, CB 2500 supports two bays for internal switches and up to 28 PCIe Generation three lowprofile slots for standard PCIe cards. Built-in logical partitioning is a key feature of Compute Blade Hitachi logical partitioning is the industry's first embedded hardware-based and hardware-assisted virtualization solution, based on proven, mainframe-class technology. There is no complex installation process: It just runs, right out of the box. Unlike emulation solutions, it doesn't slow application performance down. And, because no software hypervisor is required, your operating system and applications do not require special drivers or software. The identical software stack is used in a logical partition as on a blade without logical partitioning enabled, simplifying management and reducing costs of operation and administration. Logical partitioning complements existing software-based virtualization solutions and can be used in conjunction with VMware or Hyper-V. You can combine all three in a single chassis, providing the greatest virtualization flexibility in the industry. CB 2500 also offers the very latest in power-saving features with management, monitoring and power-capping capabilities, based on a foundation of 94% efficiency "80 Plus" Platinum certified power supplies. CB 2500 is not only powerful and efficient, but manageable and flexible, too. You can configure and administer CB 2500 via a Web-based HTML browser that supports secure encrypted communications, or leverage the optional Compute Blade management suite to manage multiple chassis via a unified GUI-based interface. You can deploy CB 2500 at the edge, application or database tiers, or all three at the same time. You don't need to choose between Microsoft Windows or Linux: You can run both in the same chassis. And CB 2500 integrates effortlessly into your network I/O infrastructure thanks to its adaptable and highly expandable I/O architecture. Enterprise-Class Capabilities Hitachi Compute Blade 2500 is a true enterprise-class blade server, and it is important to understand exactly what that term means. It is "enterprise-class" in terms of performance, scalability, reliability and configuration flexibility, as outlined below: Performance. CB 2500 offers blade options supporting Intel Xeon E5 and E7 series processors with up to two CPUs per blade. It meets the performance needs of large-scale systems that require extremely high compute power and I/O (via the hybrid I/O subsystem). In addition, CB 2500 also supports multiblade SMP capabilities on high-performance CB520X blades, allowing aggregation of up to four blades to create a single server environment. Scalability. The robust, rack-mountable 12U chassis of CB 2500 houses up to eight E7-based server-blade modules or up to 14 E5-based blades (or a combination). With the CB520X blade, four blades supporting up to two processors can be aggregated together supporting up to 120 cores per environment (240 cores per CB 2500 chassis). Memory is expandable up to 6TB (with 32GB DIMMs), and the I/O subsystem supports up to 16 expansion mezzanine cards and 16 PCIe cards for a single environment. You can also scale up the virtualization capability: The logical partitioning feature from Hitachi supports configurations of up to 30 LPARs per environment. Reliability. CB 2500 chassis is fully redundant and components are hot-swappable. These components include: redundant switch and management modules, extremely reliable backplane and I/O, N +1 or fully redundant power supply modules, and N+M model; failover protection follows. There are "M" backup blades for every "N" active server blade, so failover is cascading. In the event of hardware failure, the system automatically detects the fault and identifies the problem by indicating the faulty module, allowing immediate failure recovery. 5

7 Configuration Flexibility. CB 2500 supports both Windows and/or Linux operating systems, and a wide range of virtualization solutions, including the native LPAR logical partitioning, providing a high level of flexibility and investment protection. The system can easily be configured to the exact number of sockets, processor cores, I/O slots, memory and other components required to optimally support your application without bottlenecks. The chassis can be configured and managed via simple GUI HTML-based Web interface, which is seamlessly integrated with the Hitachi Command Suite (HCS) tools used to manage Hitachi storage products. Workload Flexibility. The enterprise-class capabilities of CB 2500 also extend to workloads. The CB 2500 allows you to run your most demanding workloads, whether they are I/O-intensive applications such as online transaction processing, Web serving or high-performance computing (HPC), with extremely high performance, reliability, manageability, scalability and flexibility. Because of this extreme flexibility CB 2500 is the ideal platform to run missioncritical applications and consolidate systems at the edge, application or database tiers or all three. Data-Center Applications Hitachi Compute Blade 2500 can be deployed in an array of data center scenarios, including those aimed towards: Consolidation. CB 2500 is an excellent platform for server and application consolidation because it is capable of running 32-bit and 64-bit applications on Windows or Linux, with enterprise-class performance, reliability and scalability. Workload Optimization. CB 2500 runs a wide range of compute-intensive workloads on either Windows or Linux, or both, making it possible to balance the overall data center workload quickly and without disruption or downtime. Resource Optimization. CB 2500 enables the IT organization to increase utilization rates for expensive resources, such as processing power, making it possible to fine-tune capacity planning, and delay or eliminate unnecessary hardware purchases. Cost Cutting, Risk and Complexity. With CB 2500, acquisition costs are lower than the UNIX servers or rackmount servers that were previously required for this class of workload. Blade servers also allow you to scale up on demand in fine-grained increments, avoiding capital expenditures. CB 2500 also reduces the risk of downtime because sophisticated RAS features are built in. And with support for industry standards such as Intel Xeon processors and PCIe slots, CB 2500 decreases the risk of technology obsolescence and protects previous investments. Balanced, Modular Architecture Hitachi Compute Blade 2500 features a very modular design to maximize flexibility (see Figure 2). All core system elements are redundant and hot-swappable, so the system can be easily expanded without downtime or unnecessary disruption to service levels. 6

8 Figure 2. All Hitachi Compute Blade 2500 modules are redundant and hot-swappable, providing high reliability and uptime. Chassis Design With a 12U chassis that is 19-inch rack compatible, Hitachi Compute Blade 2500 accommodates up to 14 server modules populated with Intel Xeon E5 processors, or up to eight blades populated with Intel Xeon E7 processors (see Figure 3). Each server blade module supports up to two processors. Figure 3. Hitachi Compute Blade 2500 chassis layout allows 19-inch rack compatibility: front (left) and rear (right). 7

9 Standard Server Blades The Hitachi Compute Blade 2500 accommodates a total of up to eight dual-socket-based E7 server modules, or up to 14 E5-based server modules (or a combination) (see Figure 4). The CB520H v3 blades support the Intel Xeon processor E5-2600v3 series processors with 24 high performance DDR4 memory slots, 2 I/O expansion mezzanine card options and two front-accessible hot-swap hard drive bays. All models support two serial-attached SCSI (SAS) hard disk drives or solid-state drives (SSDs) with onboard RAID protection and super-capacitor-based backup. Onboard high-speed Ethernet ports are also provided. The ports can be connected to the backplane via a low-cost pass-through module. Lights-out management via HTML Web interface supports IP-based capabilities for remote access, virtual media support and frontside USB ports for direct access to the blade. Figure 4. Hitachi Compute Blade 2500 employs the CB520H server module. CB520X SMP Blade Unique among x86-based servers, the CB520X Hitachi Compute Blades can be connected together to grow blade capacity from two to eight sockets (configured as a single high-capacity blade) simply by adding and linking additional blades (see Figure 5). Figure 5. Hitachi Compute Blade: CB520X The CB520X blades are full width and each contains two Intel Xeon E7v3 series processors with 48 DIMM slots, two HDD bays and up to four optional mezzanine slots. The CB520X blades feature a front-side connector, which can be used to connect either two or four blades to create a single four- or eight-socket blade system (see Figure 6). The CB 2500 chassis can accommodate eight-socket CB520X blade configurations (up to two). 8

10 Figure 6. Hitachi Compute Blade CB520X allows incremental expansion from two to eight-socket blade configurations. With support for Microsoft Windows, Red Hat Linux, VMware ESXi and others, Hitachi Compute Blade 2500 gives you the option of running multiple operating systems at the same time and in the same chassis for multiple applications. Or, you can run them (using Hitachi LPAR) on the same blade. For example, in a virtualized environment on a single active server module, you can allocate 50% of CPU resources to Windows and 50% to Linux applications. And you can change the allocation dynamically as workload requirements shift. This provides flexibility for accommodating spikes in demand for specific application services. In addition, the system can be configured to dynamically reassign unused CPU resources from one partition to other partitions where CPU resources are under stress, and back again on demand. PCIe Expansion Blade Standard-width compute blades can be expanded to accommodate up to four additional PCIe cards by the addition of the PCIe expansion blade (see Figure 7). Figure 7. Hitachi Compute Blade server s CB520H blade capability may be extended with a PCIe expansion blade. The PCIe expansion blade occupies the slot adjacent to its host compute blade, effectively creating a combined doublewide blade. The bay can be configured to support a single full-height double width GPU card, for example, or as many as four low-profile cards. 9

11 Hybrid I/O Hitachi Compute Blade 2500 server modules have the ability to support both switch modules and direct PCIe I/O interfaces, allowing each blade to be configured differently. Each blade can access a common, unified, shared-switch network across all the blades while also supporting unique I/O interfaces. This allows you to standardize the switch interface, accommodate workload-specific I/O interfaces, or both, using the same system. This capability is particularly useful if you have separate server, storage and network organizations, allowing storage resources to be managed outside of the box. Mezzanine Cards and PCIe Slots For additional I/O versatility, Hitachi Compute Blades allow mezzanine I/O expansion cards to be used to add capability (see Figure 8). Also, uniquely for a blade server, it allows the connection of standard half-height PCIe Gen 3 cards with sufficient bandwidth for the most demanding I/O-intensive applications. Such applications may include online transaction processing, high-performance computing, simulations and modeling, or batch jobs with heavy transactional loads. Figure 8. Hitachi Compute Blade 2500 architecture provides I/O versatility. Quad-port gigabit Ethernet (GigE) mezzanine option cards are supported, allowing four or eight GigE NIC ports per blade, in addition to those that can be provided by the PCIe slot cards, which provides enough I/O to tackle any virtualized workload environment. 1/10GbE Switch Module The Hitachi Compute Blade embedded 1/10GbE switch module is a managed, standards-based layer-3 switch that provides 1 and 10 gigabit networking required in today's enterprise data centers. The switch provides up to 28 internal ports for connecting CB 2500 server modules and up to 10 copper and four optical ports externally to connect other networked resources within the corporate networking structure. In addition, two separate 1GbE ports are provided for internal management connection. The Hitachi Compute Blade embedded 1/10GigE switch module can be configured for high availability and fault tolerance when a second redundant switch module is added. 10/40GbE Data Center Bridging (DCB) Switch Module The CB /40GbE DCB switch is a state-of-the-art 10/40Gb embedded switch with up to 42 internal 10GbE ports and 14 external 10GbE ports with optional 4 40GbE ports. It offers wire-speed throughput and non-blocking cut-through architecture, providing industry-leading performance and ultra-low latency. It enables CB 2500 to support flexible connectivity options for cloud architectures, including lossless Ethernet fabrics. The switch provides CB

12 administrators with the ability to enhance their hierarchical network architectures, deploy flatter scale-out fabrics, or converge networks when deploying virtualization and cloud IT infrastructures. Its rich set of Layer 2 features can be deployed into classic 1Gb and 10Gb architectures, preserving existing network designs and cabling. Dual-speed-capable (1Gb/sec or 10Gb/sec) external ports are provided as well as optional 40GbE ports for data centers migrating to next-generation 40Gb/sec high-performance architectures. They are supported by both 1Gb/sec RJ-45 connectors and 10Gb/sec twinax copper or optical connectors for ultimate flexibility. Data center bridging and multihop Fibre Channel over Ethernet (FCoE) capabilities enable lossless unified storage connectivity, and convergence of storage and LAN traffic to reduce connectivity costs. Its automatic migration of port profiles (AMPP) feature simplifies virtualized server management by enabling seamless virtual machine (VM) mobility, further simplifying management and reducing operational costs. Naturally, the DCB switch is integrated with Hitachi chassis management software, enabling end-to-end management of CB Eco-Efficient Power and Cooling Hitachi Compute Blade 2500 accommodates up to six power supplies in the chassis and can be configured with mirrored power supplies (2N) or N+1 power supplies, providing backup on each side of the chassis and higher total reliability. Cooling is provided by efficient, variable-speed, redundant fan modules. CB 2500 also features the power capping function, which optimizes the power consumption from server blades by controlling the frequency (CPU steps) according to processor service rate. This function saves approximately 16% of power consumption by server blades. In addition, CB 2500 can provide real-time monitoring and historical data of power consumption in the server chassis. The visualized information helps reduce equipment costs, enabling facility planning for equipment installation and expansion. Hitachi Compute Blade Management Hitachi Compute Blade 2500 supports up to two management modules for redundancy. Each module is hot-swappable and supports live firmware updates without the need for shutting down the system. This makes it your best choice if you are looking for a highly available system. Each module supports an independent management LAN interface from the data network for remote and secure management of the chassis and all blades. Each module supports a serial CLI and a Web interface. The management modules also support SNMP and alert notification so that administrators are always notified of any issues. HTML-Based Web Interface Basic chassis and blade operations are managed via Hitachi Compute Systems Manager (HCSM). This secure HTML Web interface allows seamless integration with Hitachi Command Suite, simplifying management of converged solutions with Hitachi storage (see Figure 9). The graphical HSCM interface simplifies system configuration and supports secure and encrypted communications, ensuring that only authorized users can access resources and only authorized resources can be accessed. 11

13 Figure 9. Hitachi Compute Systems Manager provides an HTML-based Web interface. KVM (keyboard-video-mouse) remote management of the blades is supported via IP with either a client-based interface, which can be installed onto a remote computer, or via the Java-based Web interface, which is accessible from any standard Web browser. The tools also support power control as well as virtual media capabilities, allowing local drives to be connected directly to the server. Logical Partitioning Embedded Virtualization Technology Logical partitioning sets a new standard for server consolidation and on-demand infrastructure provisioning. As the industry's first hardware-embedded virtualization technology for blade computing, LPAR delivers new capabilities that other popular virtualization solutions do not provide. At the same time, LPAR works well in conjunction with VMware and Microsoft Hyper-V within a single system to increase configuration flexibility. Overview and Key Benefits Logical partitioning delivers high performance, extreme reliability, security and transparent virtualization for the Intel Xeon processor E5 series server modules on Hitachi Compute Blade It supports numerous guest operating systems (OSs), including Red Hat Linux and Windows, and it does not intrude at the OS level, maximizing security, performance and simplicity. It keeps the data center agile and responsive to fast-changing business requirements. Whether the environment is running on a bare-metal server or on LPAR, there is no need for additional drivers or changes to applications. Because logical partitioning is built into the blade firmware, there is no installation and setup required, reducing total acquisition costs and simplifying the move to a partitioned environment. You can activate logical partitioning or de-activate it quickly and easily via the management console. Logical partitioning allows you to create multiple independent logical partitions (LPARs), which run on specific hardware resources uniquely allocated to that partition by the administrator. Each logical partition appears to its operating system to be an independent physical server. 12

14 CB 2500 offers two deployment models for logical partitioning: The "Essential" model is included with each system and allows you to create four LPARs per blade at no additional cost. The "Enterprise" model requires an additional license and allows the creation of up to 30 LPARs per blade on CB Logical partitioning is firmware based and thus has a natural performance advantage over host-emulation virtualization offerings, since guest OSs can be directly executed without host intervention. Logical partitioning leverages Intel Virtualization Technology (VT) to ensure that processor performance is optimized for the virtual environment. Equally important, this technology utilizes a standard filesystem (NTFS, the standard filesystem of modern Microsoft Windows OSs) and standard OS drivers, simplifying the administrator's job significantly. With logical partitioning there is no need for exclusive and costly file management, migration and/or backup tools for virtualization platforms. Logical partitioning is fast to install, configure and deploy since all virtualization files are stored in the firmware and there is no need to install or upgrade each blade with virtualization software. It also means better performance because less overhead is required for filesystem format conversions or driver emulations to consume precious CPU cycles. Drivers required are the same for either standard or partitioned environments, adding to management simplicity. Performance and Security Features Based on many years of Hitachi experience developing virtualization technology for the mainframe world, logical partitioning brings true enterprise-class performance and security to virtualization for the first time in a blade-computing environment. This technology can partition physical server resources by constructing multiple LPARs, which are physically separated, with each environment running independently. A different operating system can run on each logical partition within a single physical server. Logical partitioning also inherits the concept of "direct execution" from the mainframe world. This means that user-level application code and OS requests are directly executed on the processor, which increases performance. Moreover, logical partitioning is tuned specifically for Hitachi Compute Blade 2500 and has been extensively tested in enterprise production environments. To increase security, each logical partition has dedicated physical memory and cannot access the memory of other partitions. This ensures that no unauthorized access to a given device or memory is possible. Files are stored in their native formats and assigned to a separate storage logical unit (LUN). Each can be assigned with different security settings. This is a more secure approach than that used some solutions, which use a single file to contain all virtual machine data. Unlike software-based virtualization solutions, a separate management interface for LPAR is built into the hardware. This resides on a different physical network than OS traffic, ensuring that user data is completely and isolated from any management traffic, and adds yet another dimension of protection and security. Hitachi Compute Systems Manager Hitachi Compute Systems Manager (HCSM) is a standalone set of optional management tools designed for data center management of multiple chassis via a graphical intuitive interface that provides point-and-click simplicity. At the system level, this software provides centralized management and monitoring of extended systems containing multiple chassis and racks. 13

15 Unified Dashboard Hitachi Compute Systems Manager allows the various CB 2500 system components to be managed through a unified interface, which is seamlessly integrated with Hitachi Command Suite (see Figure 10). When rack management is used, an overview of all Hitachi Compute Blade racks, including which servers, storage and network devices are installed, can be quickly and easily obtained. In the event of any system malfunction, the faulty part can be located at a glance. In addition, HCSM software provides the ability to define and manage the logical system configuration of each element to be managed by using the service name. With traditional blade servers, management of both the logical system and the system's physical resources is required. When definitions are made with service names (such as sales or stock) within Hitachi Compute Blade management suite, there is no longer any need for administrators to concern themselves with the management of physical resources. HCSM provides centralized system management and control of all server, network and storage resources. This includes the ability to set up and configure servers, monitor server resources, integrate with enterprise management software (SNMP), phone home and manage server assets. Figure 10. Hitachi Compute Systems Manager offers a unified view of platform management with Hitachi Command Suite. 14

16 Deployment Manager Deployment manager allows the mass deployment of system images, patches and hot-fix updates for fast, effective server installation and patch management. You can deploy system images and updates across multiple chassis in multiple locations. In addition, Hitachi also offers backup capabilities with the deployment feature. N+1 or N+M Cold Standby Failover Hitachi Compute Blade maintains high uptime levels through sophisticated failover mechanisms. The N+1 cold standby function enables multiple servers to share a standby server, increasing system availability while decreasing the need for multiple standby servers or costly software-based high-availability servers. It enables the system to detect a fault in a server blade and switch to the standby server, manually or automatically. The hardware switching is executed even in the absence of the administrator, enabling the system to return to normal operations within a short time. With the N+M cold standby function, there are "M" backup server blades for every "N" active server blade, so failover is cascading. In the event of multiple hardware failures, the system automatically detects the fault and identifies the problem by indicating the faulty server blade, allowing immediate failure recovery. This approach can reduce total downtime by enabling the application workload to be shared among the working servers. Hitachi Compute Blade 2500 Specifications TABLE 1.
