Optimized for virtualization and database applications with maximummemory and compute capacity in a bladePlease see the Legal Information section for important notices and information. 10.Light Path DiagnosticsLight path diagnostics enables a technician to quickly identify and locate a failed or failingsystem component, such as a specific blower module or memory DIMM. This enables quickreplacement 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 showpossible component failures. This lets the servicer identify the failing component without theneed to or remove the blade server from the chassis. The light path diagnostics panel tells theservicer which component of the affected server requires attention.In addition, many components have their own identifying LEDs. For example, each of thememory modules has an LED next to the socket, as do both processors. This allows the servicerto easily identify exactly which component needs servicing. By following the “light path,” thecomponent can be replaced quickly, and without guesswork. (Note: In the event of a failedDIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the systemto continue running, with reduced memory capacity, until serviced.)Gigabit Ethernet ControllerThe HX5 includes a dual-port integrated Broadcom BCM5709S Gigabit Ethernet controller forup to 10X higher maximum throughput than a 10/100 Ethernet controller. The controller offersTOE (TCP Offload Engine) support, as well as failover and load balancing for betterthroughput and system availability. It also supports highly secure remote power managementusing 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 foradditional ports. For example, the CIOv slot can hold a 2-port card, the CFFh slot supports a 4-port card, and a bridge module can add another 2 ports, for a total of 10 Gigabit Ethernet portsper HX5 blade.High-Performance Adapter SlotsThe 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 expansioncard is installed in the upper I/O slot. When SSDs are installed, both I/O slots are still availablefor 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/full-length x16 physical/x8 electrical (4GBps) PCIe Gen 1 expansion card slots, supportingadapters of up to 25W apiece to an HS22. One BPE3 can be connected per HS22 blade, for atotal of 3 available slots (1 in the blade and 2 in the expansion unit). Note: The BPE3 reservesthe 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 1standard full-height/full length and 1 standard full-height/half-length x16 physical/x8mechanical (8GBps) PCIe Gen 2 expansion card slot per HS22 blade. These slots support twoindustry-standard PCIe adapters, up to 75W per adapter. The BladeCenter PCI Express Gen 2Expansion Blade offers a unique stacking feature that allows clients to stack up to 4 expansionblades per HS22 blade, offering up to an additional 8 PCIe slots per HS22 blade. Note: Unlikethe 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 unitsto one blade server is much more cost-effective than installing multiple blade servers for thesame 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 ChassisIBM’s blade architecture offers five choices of compatible and interoperable chassis in which touse various blade servers. Each chassis serves different customer needs. The BladeCenter S isa small, entry-level chassis designed for office environments. The original chassis (refreshedwith the latest Advanced Management Modules and power supply modules) offers maximumdensity, great flexibility and a wide variety of expansion options at an entry-level price. The next-generation BladeCenter H chassis offers all of BladeCenter’s capabilities, and adds high-performance features, including 10Gb fabric support. If you need a ruggedized chassis (forexample, government/military or telecom), BladeCenter T offers special features optimized forthose environments. The next-generation BladeCenter HT is a high-performance ruggedizedtelecommunications platform, also supporting 10Gb fabrics. HX5 is supported in the BladeCenter
