The blade server uses the following features and technologies:
v Baseboard management controller (BMC)
The enhanced BMC for the JS12 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
v Disk drive support
The blade server supports two 2.5 inch (small-form-factor) Serial Attached SCSI
(SAS) hard disk drives.
v IBM Director
IBM Director is a workgroup-hardware-management tool that you can use to
centrally manage the JS12 blade server.
For more information, see the IBM Director documentation on the IBM Director
CD.
v Impressive performance using the latest microprocessor technology
The blade server comes with a POWER6 dual-core microprocessor.
v 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 does not
require the shared Ethernet adapters of Virtual I/O Server. TCP advanced
features include hardware de-multiplexing and per connection queues.
v I/O expansion
The blade server has connectors on the system board for optional PCI-X and
PCIe expansion cards, such as Fibre Channel and InfiniBand expansion cards, for
adding more network communication capabilities to the blade server.
v Large system memory capacity
The memory bus in the JS12 Type 7998 Model 60X blade server supports up to
64 GB of system memory. For the official list of supported very-low-profile, 18.3
mm DIMMs, see the ServerProven Web site at http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
v Light path diagnostics
Light path diagnostics provides light-emitting diodes (LEDs) to help you
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.
