expansion units to one blade server is much more cost-effective than installing multiple blade
servers for the same number of adapter slots. (
Note:
A maximum of
one
CFFh card is
supported.)
In addition to GPUs, other adapters up to 75W can be used to connect to BladeCenter switch
modules, including Fibre Channel, additional Gigabit Ethernet modules, 10Gb Ethernet,
Converged Network Adapters (CNAs), InfiniBand, SAS, etc.
Disk Controllers
All HS22V models include an integrated
LSI 1064E SAS/SATA
controller. This controller
supports up to
two
internal
SAS
or
SATA
HDDs
or
two
internal
solid-state drives
and offers
hardware
RAID-0
/
1/1E
support. (RAID-1E requires 3 or more drives.)
256MB
of optional battery-
backed cache memory is available.
An optional
ServeRAID-MR10ie
controller (CIOv form-factor) adds
RAID-5/50/6/60
support for
direct-attach
BladeCenter S
storage or external IBM
System Storage
EXP700, EXP710, or
EXP3000, along with
256MB
of cache memory and battery backup.
These controllers provide data transfer speeds of up to
3Gb
per second
6
in
each
direction (
full-
duplex
) across the SAS bus, for an aggregate speed of
6Gbps
(
600MBps
). The serial design of
the SAS bus allows maximum performance to be maintained as additional drives are added.
High Performance/High-Availability Internal Storage
The HS22V supports up to
two fixed 1.8-inch solid-state
drives (SSDs) internally:
•
SATA-based solid-state
—
50GB
capacity (
100GB
maximum)
High I/O Performance
– Offers up to 8X more IOPS than HDDs (67/33% read/write OLTP transaction base mix);
– Optimized for heavy mix of read and write operations, such as transaction processing, media
streaming, surveillance, file copy, logging, backup / recovery, and business Intelligence
Lower-Cost IOPS Performance
– Yields better $/IOPS: lower capacity (GB) required to achieve higher IOPS
– Consumes less energy and produces less heat than a conventional disk drive
Superior Uptime
– 3X the reliability of mechanical disk drives
7
– No moving parts to fail
– Enterprise wear-leveling to extend life even further
Full OS Support
– Supports all ServerProven OSes
Due to the statistically higher failure rates for traditional spinning media, IBM recommends the
use of the solid state drives (SSDs) as an alternative. They store data on flash memory chips,
rather than on magnetic media. Like HDDs, SSDs can be used as boot media and for random
access storage. However, SSDs offer higher thresholds of shock and vibration, and a higher
operating temperature range (between 0 and 70 degrees C). This yields a failure rate only one-
third that of HDDs (approximately 3,000,000 hours MTBF vs. 1,000,000 hours). In addition, the
IBM
50GB 1.8” Solid State Drive
requires only
2W
. This reduces the storage power
requirement and heat output by as much as
80%
, compared to 2.5-inch HDDs. If used as a boot
device, no special device drivers are required. Additional storage is available via the BladeCenter
S chassis.

Data transfer rates depend on many factors and are often less than the maximum possible.
