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.
The optional
ServeRAID-MR10ie
controller (CIOv form-factor), with up to
6Gbps
throughput per
SAS port, adds
RAID-5/50/6/60
support and
256MB
of cache memory and battery backup, as
well as support for direct-attach
BladeCenter S
storage or external
System Storage
expansion
units.
I/O Slots
— The HS22 supports the addition of a
PCIe I/O Expansion Unit 3
, which

PCIe slots.
External Storage
— The
IBM
System Storage DS3000, DS4000, DS5000
,
and
DS8000
series, as well as the
System Storage N3000, N5000, N6000
, and
N7000
series, comprise a
powerful and broad shared storage family with integrated management software designed to
meet midrange and enterprise needs. For lower-end needs, IBM offers the System Storage
EXP810
and
EXP3000
storage expansion units.
Additionally, external LAN-attached tape storage is available.
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 HS22 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.
