standard HDDs and SSDs. This makes them ideal for virtualized servers running multiple tasks,
requiring both write- and read-intensive storage media. As flash media they also offer a
predictable lifetime, compared to the sporadic failure rate of HDDs, using N+1 chip-level
redundancy and 11-bit ECC protection.
Note:
The High IOPS Adapters require a BPE4 expansion unit.
If you need more storage space, terabyte capacities are possible with optional external direct-
attach, NAS, and SAN storage solutions.
External Tape Storage
The HS22V supports various external rack-mounted SAN-attached tape drives. Supported tape
technologies include:
•
IBM System Storage TS2230 Express Tape Drive
•
IBM System Storage TS2240 Tape Drive Model S4E
•
IBM System Storage TS2900 Tape Autoloader
•
IBM System Storage TS3100 Tape Library
•
IBM System Storage TS3200 Tape Library
•
IBM System Storage TS3310 Modular Tape Library
•
IBM System Storage TS3500 Tape Library
Gigabit Ethernet Controller
The HS22V includes a
dual-port
integrated
Broadcom BCM5709S
Gigabit Ethernet controller
for up to 10X higher maximum throughput than a 10/100 Ethernet controller. The controller offers
TOE
(TCP Offload Engine) support, as well as
failover
and
load balancing
for better throughput
and system availability. It also supports highly secure remote power management using
IPMI
2.0
,
plus Wake on LAN
®
and PXE (Preboot Execution Environment) Flash interface.
If
2
ports aren’t enough, optional
2-port
or
4-port Ethernet
expansion cards can be used for
additional ports. For example, the
CIOv
slot can hold a
2-port
card and the
CFFh
slot supports a
4-port
card, for a total of
8
Gigabit Ethernet ports per HS22V blade. Using
BladeCenter Virtual
Fabric
increases the number of available ports to
12
.
Light Path Diagnostics
Light path diagnostics enables a technician to quickly identify and locate a failed or failing system
component, such as a specific blower module or memory DIMM. This enables quick replacement
of the component, which helps increase server uptime and lower servicing costs.
The front of each blade server—and the chassis itself—has an LED indicator light to show
possible component failures. This lets the servicer identify the failing component without the need
to or remove the blade server from the chassis. The light path diagnostics panel tells the servicer
which component of the affected server requires attention.
In addition, many components have their own identifying LEDs. For example, each of the
memory modules has an LED next to the socket, as do both processors. This allows the servicer
to easily identify exactly which component needs servicing. By following the “light path,” the
component can be replaced quickly, and without guesswork. (
Note:
In the event of a failed
DIMM, the system will restart and mark the DIMM as bad while offline, thus allowing the system
to continue running, with reduced memory capacity, until serviced.)
BladeCenter Chassis
IBM’s blade architecture offers
five
choices
of compatible and interoperable chassis in which to
use various blade servers. Each chassis serves different customer needs. The new
BladeCenter
S
is a small, entry-level chassis designed for office environments. The original
BladeCenter E
chassis (refreshed with the latest Advanced Management Modules and power supply modules)
offers maximum density, great flexibility and a wide variety of expansion options at an entry-level
price. The next-generation
BladeCenter H
chassis offers all of BladeCenter’s capabilities, and
adds high-performance features, including 10Gb fabric support. If you need a
ruggedized

According to internal IBM testing, the typical
maximum IOPS
of a 600GB 15K
3.5
-inch hot-swap SAS HDD is ~
400
(4K random reads),
while the typical IOPS of a 640GB High IOPS SSD PCIe adapter is ~
200,000
, or
~500x
. The typical
bandwidth
of the same HDD =
~
195MBps
(64K sequential reads), while the typical bandwidth of a 640GB High IOPS MLC adapter is ~
1.5GBps

97,014 IOPS / 9W =
10,779 IOPS

per watt (640GB adapters). 400
IOPS / 16.5W = ~
24 IOPS
