highly available boot drive, for storing disk images, or for other uses that stress read performance.

Additional direct-attach storage is available via the BladeCenter S chassis.

High IOPS SSD PCIe Adapters — For storage media offering up to 500 times the I/O operations

per second (IOPS) and up to 7.7 times the bandwidth of 15,000-RPM HDDs, IBM offers the

160GB High IOPS SS Class SSD PCIe Adapter, the 320GB High IOPS SS Class SSD PCIe

Adapter, the 320GB High IOPS MS Class SSD PCIe Adapter, and the 320GB High IOPS SD

Class SSD PCIe Adapter, as well as the 640GB High IOPS MLC Duo Adapter. These adapters

offer near-DRAM performance, with extremely high data retention (up to 25 years) and RAID-

grade data protection, and can be used in addition to SSDs. (The High IOPS adapters require a

BPE4 expansion unit.)

ServeRAID Controllers — System x servers using ServeRAID technology allow organizations to

build a reliable foundation for business-critical computing. IBM ServeRAID technology allows an

array consisting of multiple physical hard disk drives to be treated as one logical drive. ServeRAID

technology also allows data to be stored redundantly, across multiple hard disk drives—

enhancing both the integrity and the availability of the data. SAS and SATA ServeRAID controllers

offer enhanced performance due to onboard processors and cache. Because IBM ServeRAID

controllers can help significantly improve data transfer rates, this technology is extremely effective

when implementing demanding, transaction-oriented applications. By employing the advanced

fault tolerance of IBM ServeRAID technology, companies can effectively implement networked

business systems that require large amounts of storage space for data and applications that must

be available for their businesses to continue operating.

External Storage — The IBM System Storage EXP810, EXP3512, and EXP3524 storage

expansion units, DS3000, DS4000, DS5000, and DS8000 series storage servers, as well as the

System Storage N3000, N5000, N6000, and N7000 series NAS units, comprise a powerful and

broad shared storage family with integrated management software designed to meet midrange

and enterprise needs. In addition, IBM Storwize

V7000 is virtual storage that offers high

efficiency and flexibility through built-in SSD optimization and “thin provisioning” technologies.

Communication Modules — The various BladeCenter chassis support integrated communication

and I/O switches and/or bridges for Gigabit and 10Gb Ethernet, Myricom, 4Gb and 8Gb Fibre

Channel, 1X and 4X InfiniBand, iSCSI, 3Gb SAS, and others. Expansion adapters for individual

HX5 blades are available to interface with these modules. The BladeCenter H and BladeCenter

HT also support the Multi-Switch Interconnect Module, which doubles the number of Gigabit

Ethernet and Fibre Channel connections available to all blades in the chassis.

Rear Door Heat eXchanger — The unit attaches to the back of an IBM S2 42U Enterprise Rack.

It is capable of removing up to 50,000 BTUs (14KVa) from the data center using water lines under

the raised floor. The door swings open for servicing.

Redundant features — Optional hot-swap drives, power supply modules, blower modules,

management modules, switches and bridges provide redundancy for the various BladeCenter

chassis.
