Chapter 1. Product overview 7

What your blade server offers
The design of the blade server takes advantage of advancements in chip
technology, memory management, and data storage.
The blade server uses the following features and technologies:
vBaseboard management controller (BMC)
The enhanced BMC for the JS23 blade server and JS43 blade server is a flexible
service processor that provides support for the following functions:
– Alert Standard Format (ASF) and RS-485 interfaces to the management
modules
– Intelligent Platform Management Interface (IPMI)
– The operating system
– Power control and advanced power management
– Reliability, availability, and serviceability (RAS) features
– Serial over LAN (SOL)
– Continuous health monitoring and control
– Configurable notification and alerts
– Event logs that are time stamped and saved in nonvolatile memory and that
can be attached to e-mail alerts
– Point-to-point protocol (PPP) support
– Remote power control
– Remote firmware update and access to critical blade server settings
vDisk drive support
The blade server supports one 2.5 inch (small-form-factor) Serial Attached SCSI
(SAS) hard disk drive.
vIBM Director
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage the JS23 blade server and JS43 blade server, including updating
the JS23 and JS43 firmware.
For more information, see the IBM Director documentation on the IBM Director
CD.
vImpressive performance using the latest microprocessor technology
The blade server comes with two POWER6™microprocessors.
vIntegrated 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 does not
require the shared Ethernet adapters of Virtual I/O Server. TCP advanced
features include hardware de-multiplexing and per connection queues.
vI/O expansion
The blade server has connectors on the system board for optional 1Xe and PCIe
expansion cards, such as Fibre Channel and InfiniBand expansion cards, for
adding more network communication capabilities to the blade server.
vLarge system memory capacity
The memory bus in the JS23 Type 7778 blade server supports up to 64 GB of
system memory. The memory bus in the JS43 Type 7778 blade server supports
