Optimized for virtualization and database applications with maximum memory and compute capacity in a blade Light Path Diagnostics Light path diagnostics enables a technician to quickly identify and locate a failed or failing system component, such as a specific blower module or memory DIMM. This enables quick replacement of the component, which helps increase server uptime and lower servicing costs. The front of each blade server-and the chassis itself-has an LED indicator light to show possible component failures. This lets the servicer identify the failing component without the need to or remove the blade server from the chassis. The light path diagnostics panel tells the servicer which component of the affected server requires attention. In addition, many components have their own identifying LEDs. For example, each of the memory modules has an LED next to the socket, as do both processors. This allows the servicer to easily identify exactly which component needs servicing. By following the "light path," the component can be replaced quickly, and without guesswork. (Note: In the event of a failed DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the system to continue running, with reduced memory capacity, until serviced.) Gigabit Ethernet Controller The HX5 includes a dual-port integrated Broadcom BCM5709S Gigabit Ethernet controller for up to 10X higher maximum throughput than a 10/100 Ethernet controller. The controller offers TOE (TCP Offload Engine) support, as well as failover and load balancing for better throughput and system availability. It also supports highly secure remote power management using IPMI 2.0, plus Wake on LAN® and PXE (Preboot Execution Environment) Flash interface. If 2 ports aren't enough, optional 2-port or 4-port Ethernet expansion cards can be used for additional ports. For example, the CIOv slot can hold a 2-port card, the CFFh slot supports a 4port card, and a bridge module can add another 2 ports, for a total of 10 Gigabit Ethernet ports per HX5 blade. High-Performance Adapter Slots The HX5 blade server includes two PCIe adapter slots. They support CFF (compact form factor) cards: one standard-speed CIOv and one high-speed CFFh card. Note: The SSD expansion card is installed in the upper I/O slot. When SSDs are installed, both I/O slots are still available for use. Adding a second HX5 blade for a 2-wide 4-socket server doubles the number of PCIe card slots. The BladeCenter PCI Express I/O Expansion Unit 3 (BPE3) adds 2 standard full-height/fulllength x16 physical/x8 electrical (4GBps) PCIe Gen 1 expansion card slots, supporting adapters of up to 25W apiece to an HS22. One BPE3 can be connected per HS22 blade, for a total of 3 available slots (1 in the blade and 2 in the expansion unit). Note: The BPE3 reserves the high-speed CFFh expansion connector in the HS22, leaving only the CIOv slot available. Similarly, the optional BladeCenter PCI Express Gen 2 Expansion Blade (BPE4) adds 1 standard full-height/full length and 1 standard full-height/half-length x16 physical/x8 mechanical (8GBps) PCIe Gen 2 expansion card slot per HS22 blade. These slots support two industry-standard PCIe adapters, up to 75W per adapter. The BladeCenter PCI Express Gen 2 Expansion Blade offers a unique stacking feature that allows clients to stack up to 4 expansion blades per HS22 blade, offering up to an additional 8 PCIe slots per HS22 blade. Note: Unlike the BPE3, the BPE4 does not reserve the high-speed CFFh expansion connector in the HS22, leaving both slots available in the server. If I/O slots are a greater need than processors or memory, attaching multiple I/O expansion units to one blade server is much more cost-effective than installing multiple blade servers for the same number of adapter slots. Adapters can be used to add fabrics to BladeCenter switch modules, including 10Gb Ethernet, additional Gigabit Ethernet controllers, CNA, Fibre Channel, InfiniBand, SAS, etc. BladeCenter Chassis IBM's blade architecture offers five choices of compatible and interoperable chassis in which to use various blade servers. Each chassis serves different customer needs. The BladeCenter S is a small, entry-level chassis designed for office environments. The original chassis (refreshed with the latest Advanced Management Modules and power supply modules) offers maximum density, great flexibility and a wide variety of expansion options at an entry-level price. The nextgeneration BladeCenter H chassis offers all of BladeCenter's capabilities, and adds highperformance features, including 10Gb fabric support. If you need a ruggedized chassis (for example, government/military or telecom), BladeCenter T offers special features optimized for those environments. The next-generation BladeCenter HT is a high-performance ruggedized telecommunications platform, also supporting 10Gb fabrics. HX5 is supported in the BladeCenter 10.
