What your blade server offers
The design of the blade server takes advantage of advancements in memory
management and data storage. The blade server uses the following features and
technologies:
v Baseboard management controller (BMC)
The baseboard management controller (BMC) is on the system board of the
blade server. The BMC operates as the service processor for the blade server
and performs several tasks, such as the following functions:
– Provides Alert Standard Format (ASF) and RS-485 interfaces to the
management modules
– Provides support for:
- Intelligent Platform Management Interface (IPMI)
- The operating system
- Power control and advanced power management
- Reliability, availability, and serviceability (RAS) features
- Serial over LAN (SOL)
BMC also provides the following features and functions:
The
– Continuous health monitoring and control
– Configurable notification and alerts
– Event logs that are time stamped and saved in nonvolatile memory and 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
– Around-the-clock access to the blade server, even if the blade server is turned
off
Disk drive support
v
The blade server supports up to two 2.5 inch 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 servers. For more information, see the IBM Director
documentation on the IBM Director CD.
v Impressive performance using the latest microprocessor technology
The blade server supports two PowerPC 970MP microprocessors. The blade
server comes with two microprocessors installed.
v Integrated network support
The blade server has two integrated (onboard) Gigabit Ethernet controllers. Each
Ethernet controller has an interface for connecting to 10/100/1000-Mbps networks
through an Ethernet-compatible switch module in the BladeCenter unit. The blade
server automatically selects between 10BASE-T and 100/1000BASE-TX
environments. Each controller provides full-duplex (FDX) capability, which
enables simultaneous transmission and reception of data on the Ethernet local
area network (LAN). Only the integrated controllers support Wake on LAN
technology.
®
6 BladeCenter JS21 Type 8844: Installation and User’s Guide
v I/O expansion
The blade server has connectors on the system board for an optional expansion
card, such as the Fibre Channel expansion card, for adding more network
communication capabilities to the blade server.
v Large system memory capacity
As of the date of this publication, the memory bus in the blade server supports
up to 16 GB of system memory. For the most current list of supported DIMMs,
see the ServerProven® list 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. For more information, see the Problem

v Power throttling
If your BladeCenter unit type supports power management, the power
consumption of the blade server can be dynamically managed through the
management module. For more information, see the management-module
documentation or http://www.ibm.com/systems/support/.
Reliability, availability, and serviceability features
Three of the most important features in server design are reliability, availability, and
serviceability (RAS). These RAS features help to ensure the integrity of the data
that is stored in the blade server, the availability of the blade server when you need
it, and the ease with which you can diagnose and correct problems.
The blade server has the following RAS features:
v Automatic error retry or recovery
v Automatic server restart (ASR)
v Built-in monitoring for temperature, voltage, hard disk drives, and flash drives
v Chipkill memory for dual inline memory modules (DIMMs)
v Customer-upgradeable basic input/output system (BIOS) code (firmware code)
v Customer support center 24 hours per day, 7 days a week
v Diagnostic support of Ethernet controllers
v DIMM failure isolation
– DIMM pair identification through troubleshooting by the user
– Single DIMM identification through troubleshooting by a service technician
Error codes and messages
v
v ECC memory
v Failover Ethernet support
v Light path diagnostics
v Peripheral component interconnect (PCI) bus parity
v Power-on self-test (POST)
v Predictive Failure Analysis (PFA) alerts
v Service processor (BMC) that communicates with the management module to
enable remote blade server management
v SDRAM with serial presence detect (SPD) and vital product data (VPD)
v System Management Services (SMS) menu support
v System error logging

Major components of the blade server
You must remove the blade server from the BladeCenter unit and remove the cover
to see the components. The following illustration shows the major components of
the blade server.
