are also supported, installed by the user on an SSD.
ESXi is fully contained on the flash drive, without requiring any disk space. 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
much like firmware. ESXi includes all the performance, scalability and compatibility features of
ESX Server, including full VMFS support across FC SAN, iSCSI SAN, and NAS, and 4-way
VSMP. Rather than management through a Service Console based on a Linux operating
system, ESXi relies on aggregate management tools, including VirtualCenter, the Remote
Command Line interface and the introduction of CIM for standards-based and agentless
hardware monitoring. Licensing works the same as for “standard” ESX Server.
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
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.)
High-Performance Adapter Slots
The HS22V blade server includes two PCIe adapter slots. They support CFF (compact form
factor) cards: one standard-speed CIOv and one high-speed CFFh.
The PCI Express I/O Expansion Unit 3 (PEU3) adds 2 standard full-height/full-length x16
physical/x8 electrical PCIe expansion card slots. Note: The PEU3 uses the high-speed CFFh
expansion connector in the HS22V, leaving the CIOv slot available.
Adapters can be used to add fabrics to BladeCenter switch modules, including 10Gb Ethernet,
additional Gigabit Ethernet controllers, CNA, Fibre Channel, InfiniBand, SAS, etc.
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.
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
