2.5-inch drives consume approximately half the
power of 3.5-inch drives.
• One optional internal SATA-based 15.8GB or 31.4GB Solid State Drive in place of the HDDs, as
either higher-reliability/higher-availability storage or as a boot-to-SAN drive.
• Two Gigabit Ethernet ports standard; plus more, using either a 2-port Gigabit Ethernet Expansion
Card, a Memory and I/O Expansion Unit, or a PCI I/O Expansion Unit II.
In addition, the various
BladeCenter chassis offer a high degree of flexibility:
• A 30mm HS21 blade server can be upgraded, via a Memory and I/O Expansion Unit to a double-
wide HS21 (with expanded capabilities). With or without the Memory and I/O Expansion Unit, the
blade can be expanded further with a

• Every HS/LS/JS blade server ever released by IBM is supported in BladeCenter H, and most are
supported in every BladeCenter chassis ever released, going back to 2002. Every switch module
released by IBM is equally compatible. (Ask HP and Dell how far back their compatibility goes.)
Future blades and fabric switches are expected to continue to be compatible with previous chassis
for the foreseeable future.

Future blades and fabric switches are expected to continue to be compatible with previous chassis
for the foreseeable future.
• A blade server has access to as many as 10 communication switches and/or bridges in one
BladeCenter H chassis. (Up to 6 switches in a BladeCenter E or BladeCenter T chassis.) And the
switches can be Ethernet, iSCSI, InfiniBand, Fibre Channel, Myrinet, or anything else designed and
ServerProven for BladeCenter use. Switches, bridges and interface cards are currently available
from such vendors as Brocade, Cisco, Intel, McData, Nortel, QLogic, Cisco Topspin and others, in
addition to IBM.

Manageability
• The HS21 blade server includes a Baseboard Management Controller (BMC) to monitor server
availability, perform Predictive Failure Analysis, etc., and trigger IBM Director alerts.
• Each BladeCenter chassis includes an Advanced Management Module to provide additional
systems management capabilities, including Web-based out-of-band control; virtual floppy and CD-
ROM support; Windows “blue screen” error capture; LDAP and SSL support; and remote redirection
of video, text, keyboard and mouse.

of video, text, keyboard and mouse.
• Integrated industry-standard IPMI 2.0 support works with the BMC to alert IBM Director to
anomalous environmental factors, such as voltage and thermal conditions. It also supports
highly
secure remote power control.
• IBM Systems Director Active Energy Manager for x86, an IBM-exclusive, is designed to take
advantage of new system power management features, by monitoring actual power usage and
providing power consumption capping features. More accurate power usage data helps with data
center construction planning and the sizing of power and cooling needs, as well as allowing you to
use available power more efficiently.

concurrent media (cMedia) access by multiple administrators at once. (This card uses a dedicated
slot and does not affect the use of PCI-X/PCIe adapters.)

• IBM Director is included for proactive systems management and works with both the blade’s
internal BMC and the chassis’ management module. It comes with a portfolio of tools, including IBM
Systems Director Active Energy Manager for x86, Management Processor Assistant, RAID
Manager, Update Assistant, and Software Distribution. In addition, IBM Director offers extended
systems management tools for additional server management and increased availability. When a
problem is encountered, IBM Director can issue administrator alerts via e-mail, pager, and other
methods.

Availability and Serviceability
• BladeCenter chassis are designed for operation with greatly reduced potential for single points
of failure. Most aspects of operation, from blade servers to communication modules, to
management modules, to power and blower modules, are
management modules, to power and blower modules, are
hot-swappable. The midplane
connections are
redundant and the other features can be made so, when used in pairs.
