Optimized for virtualization and database applications with maximum memory and compute capacity in a blade • Solid state drives (SDDs) use only 2W of energy per drive, vs. 9-10W for 2.5-inch HDDs. This is as much as 80% less energy than a HDD would use (with a corresponding reduction in heat output). • The extremely high degree of integration in the various BladeCenter chassis reduces the need for server components, replacing numerous fans, KVM and Ethernet cables, power supplies, external switches and other components with fewer shared hot-swap/redundant components in the BladeCenter chassis itself. This integration also can greatly reduce the amount of power consumed and heat produced, relative to an equivalent number of 1U servers. This can significantly reduce a data center power bill. The reduced data center footprint can also save on infrastructure cost. • The midplanes used in all chassis provide high-speed blade-to-blade, blade-to-switch-module and module-to-module communications internally as well as externally. The midplanes used in the BladeCenter H and BladeCenter HT chassis provide four 10Gb data channels to each blade, and supports high-speed switch modules, including 4X InfiniBand and 10Gb Ethernet. • The various BladeCenter chassis use ultrahigh efficiency power supplies. Most industry-standard servers use power supplies that are between 70-75% efficient at converting power from AC wall current to the DC power used inside servers. BladeCenter power modules are up to 92% efficient. This helps save even more money, as more of the power input you are paying for is used for processing, rather than released into the data center as waste heat that requires even more energy to cool. • BladeCenter design also reduces the number of parts required to run the system. Sharing fans, systems management, and optical media means fewer parts to buy and maintain, and fewer items that can fail and bring the overall solution down. Flexibility The HX5 has the ability to grow with your application requirements, thanks to: • Up to two multi-core Xeon processors (up to 16 cores) per HX5 blade server; up to 2 blades (4 processors, 32 cores) per server. • The ability to grow from a single-wide 2-socket server blade to a double-wide 4-socket server configuration, optimized for compute-intensive workloads with up to 4 processors/32 cores, 256GB of memory, 4 PCIe cards, 16 I/O ports, and 4 SSDs), or for memory-intensive workloads with up to one server blade and one MAX5 memory expansion blade (2 processors/16 cores, 320GB of memory, 4 PCIe cards, 16 I/O ports, and 4 SSDs). • A choice of processor speeds (1.86 or 2.0GHz), and shared L3 cache sizes (12MB, 18MB, or 24MB). • Up to 128GB of system memory in 16 DIMM slots. Using two blade servers the HX5 can support up to 256GB; or up to 320GB using one HX5 and one MAX5 memory expansion blade. • Up to two internal hot-swap 1.8-inch solid state drives, and access to terabytes of external storage via the BladeCenter S chassis or IBM System Storage™ SAN and NAS storage devices. SSDs consume only 10-20% of the energy required by 2.5-inch HDDs. • Two Gigabit Ethernet ports standard, plus optional 2-port or 4-port expansion cards or a BladeCenter PCI Express I/O Expansion Unit 3. One HX5 model includes a 10Gb expansion card (optional in the other models). In addition, the various BladeCenter chassis offer a high degree of flexibility: • They support configurations that are 30mm or 60mm wide, with a variety of I/O options, depending on need. • When installed in a BladeCenter H high-speed switch bay, the optional Multi-Switch Interconnect Module doubles the number of Gigabit Ethernet and Fibre Channel connections to every blade in the chassis (up to 8 or 12 ports, depending on the blade server). • Xeon processor-based HX5 blades can be used in the same chassis as Intel processor-based HC10, HS12, HS20, HS21, HS21 XM, HS22, HS22V, and HS40 blades; AMD Opteron processorbased LS20, LS21, LS22, LS41 and LS42 blades; IBM PowerPC® processor-based JS20, JS21, and JS22 blades; POWER6® processor-based JS12, JS23, and JS43 Express blades; POWER7® processor-based PS700, PS701, and PS702 blades; Cell Broadband Engine™ processor-based QS21; and IBM PowerXCell™ processor-based QS22 blades. Depending on the blade servers used, the various BladeCenter chassis support Microsoft Windows, Linux, Novell Netware, IBM AIX® and Sun Solaris 10 operating systems in the same chassis. • Most HS/LS/JS/QS blade servers ever released by IBM are supported in every BladeCenter chassis ever released, going back to 20023. Every switch module released by IBM is equally compatible. (Ask HP and Dell how far back their compatibility goes.) • A blade server has access to as many as 10 communication switches/bridges in a BladeCenter 3 Some older chassis may require power module and management module upgrades. 3.
