The JS23 blade server supports one 2.5 inch hard disk drive.The JS43
blade server can support up to two 2.5 inch hard disk drives. The disk
drives can be either the small-form-factor (SFF) Serial Attached SCSI
(SAS) or the Solid state drive (SSD).
򐂰 IBM Director

to centrally manage the JS23 blade server and JS43 blade server,
including updating the JS23 and JS43 firmware.
򐂰 Integrated network support
The blade server has two integrated (onboard) 1 gigabit-per-second (Gbps)
Host Ethernet Adapter (HEA) controllers that provide advanced acceleration
features, such as checksum offload, TCP large send, and jumbo frames.
Capabilities include virtualized adapter sharing among logical partitions that

diagnose problems. An LED on the blade server control panel is lit if an
unusual condition or a problem occurs. If this happens, you can look at the
LEDs on the system board to locate the source of the problem.
򐂰 Power throttling
If your BladeCenter unit supports power management, the power
consumption of the blade server can be dynamically managed through the
management module.
