Intelligent Platform Management Interface (IPMI) 2.0-compliant systems management. It
provides a number of important system functions, including:
Monitoring of system and battery voltage, system temperature, fans, power supplies, processor and
DIMM status
Fan speed control
Product ID and Family ID detection
Highly secure remote power on/off
System reset control
NMI/SMI detection and generation
System diagnostic LED control (power, HDD, activity, alerts, heartbeat)
IPMI over LAN
Serial Over LAN
Proxy server support
LAN messaging and alerting
Text console redirection over LAN
VLAN support
Enhanced authentication and encryption algorithms (RMCP+, SHA-1, AES)
Local update of BMC firmware
Firmware firewall
Support for IPMI v2.0 compliant management software (e.g., xCAT)
Other mandatory and optional IPMI BMC functions
The BMC, via the management module, alerts IBM Director to anomalous environmental factors,
such as voltage and thermal conditions—even if the server has failed.
Other systems management features offered for the combination of blade server and chassis
include:
Predictive Failure Analysis for system processors, memory and HDDs, as well as chassis switch
modules, blower modules and power modules
Web-based out-of-band control
Windows “blue screen” capture
Remote virtual media
High-speed remote redirection of PCI video, keyboard and mouse
SSL (Secure Socket Layer) and LDAP (Lightweight Directory Access Protocol) support
In order to put control of processor power-saving features at the fingertips of administrators, IBM
developed IBM PowerExecutive
. IBM PowerExecutive is designed to take advantage of new
processor features, such as balancing the performance of the system according to available
power input. It provides the ability to plan and predict power consumption based on your
BladeCenter hardware configuration. It also allows you to reduce the infrastructure required for
redundancy, by using fewer servers on smaller power feeds and potentially lowering your overall
data center support costs. It does this by inventorying all components at the blade level, then
adding up the power draw for each blade and tracking that usage. In failure mode,
PowerExecutive (through the BladeCenter Management Module) might request that certain
blades in each domain throttle down to reduce power consumption.
Automatic Server Restart (ASR) helps reduce downtime by restarting the server automatically
in the event of a system lockup. ASR technology is a combination of hardware circuitry tied into
the server’s system reset function and a device driver. As long as the server continues running,
the ASR watchdog timer will keep being reset, but if the operating system crashes or the
hardware freezes somehow the ASR software will be unable to reset the hardware timer. If the
timer is not reset within five minutes, it automatically triggers the ASR hardware, which
immediately restarts the server (and logs an ASR event with IBM Director). These features are
designed so that no more than five minutes can pass before the server is restarted.
Text and Graphics Console Redirect support allows the administrator to remotely view HS21
text and graphics messages over serial or LAN.
Wake on LAN permits the server to be remotely powered on if it has been shut off. Once
powered up, the server can be controlled across the network, using the Preboot Execution
Environment (PXE).
Like Wake on LAN, PXE is system firmware. It allows software such as the IBM Remote
Deployment Manager to take control of a system before the BIOS, operating system or
applications are loaded (using Wake on LAN/PXE) and lets an administrator perform many low-
