including full
VMFS support across FC SAN, iSCSI SAN, and NAS, and 4-way VSMP. Because
it runs from flash memory, it’s extremely fast and ideal for diskless configurations. It also offers
enhanced security, because it runs without an operating system-based console and is
updated/patched mush like firmware. Licensing works the same as for “standard” ESX Server.
External Tape Storage
The HS22 supports various external rack-mounted SAN-attached tape drives. Supported tape
technologies include:
• IBM LTO3 2U Autoloader
• IBM LTO3 4U Tape Library
• IBM System Storage TS2230 Express Tape Drive
• IBM System Storage TS2240 Tape Drive Model H4S
• IBM System Storage TS3100 or TS3200 Tape Library
• IBM System Storage TS3310 Modular Tape Library
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.)
Gigabit Ethernet Controllers
The HS22 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.
For additional Gigabit Ethernet controllers, an optional
2-port or 4-port Ethernet expansion
card adds additional Gigabit Ethernet ports.
High-Performance Adapter Slots
The HS22 blade server includes
two x8 PCIe adapter slots. They support CFF (compact form
factor) cards: one standard-speed
CIOv and one high-speed CFFh.
Support for one of two possible expansion units is planned for sometime after general
availability (GA) to increase the number of expansion card slots available. Only one may be
used as each will utilize the one high-speed expansion connector in the HS22:
Adapters can also be used to add interfaces to BladeCenter switch modules, including Fibre
Channel, additional Gigabit Ethernet modules, InfiniBand, SAS, etc.
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 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 new high-performance features. If you need a
ruggedized
chassis (for example, government/military or telecom),
BladeCenter T offers special features
optimized for those environments. (HS22 is not currently supported in the BladeCenter T.) The
next-generation
BladeCenter HT is a high-performance ruggedized telecommunications
platform. There is a high degree of interchangeability and compatibility of features among the
chassis. Any or all of these chassis can be installed in a rack along with other rack-optimized
equipment.
