Optimized for virtualization and database applications with maximum

memory and compute capacity in a blade

(depending on the system configuration), for high performance and wide memory bandwidth.

• The 7873 machine type supports low-voltage 1.35V DIMMs.

• By scaling to 2 blade servers, the HX5 can support up to 512GB of memory—enough for even the

most demanding virtualization, database, or ERP needs. If even that’s not enough memory, using

one blade server and one memory expansion blades, the HX5 can scale to 640GB.

• Alternatively, with 40 DIMM slots the server and MAX5 can be populated with inexpensive 2GB

DIMMs (for 80GB), while gaining the performance boost from using 8 memory controllers (4 in the

server and four more in the MAX5 unit).

• Embedded virtualization (optional on all models) offers extremely high performance, enhanced

security, and a zero-gigabyte HDD footprint. (In other words, no mechanical HDD to fail.)

• 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:

• 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/40 cores, 512GB

of memory, 4 PCIe cards, 16 I/O ports, and 4 SSDs) in two server blades; or for memory-intensive

workloads with one server blade and one MAX5 memory expansion blade (2 processors/20 cores,

640GB of memory, 4 PCIe cards, 16 I/O ports, and 4 SSDs).

• A choice of processor speeds (1.73 to 2.0GHz), and shared L3 cache sizes (12MB, 18MB, 24MB, or

30MB).

• 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 processor-based

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
