Energy-Smart Features
IBM servers work hard to keep your energy bills low—from high-efficiency power supplies and
fans to lower-draw processors and memory. Technologies such as these, along with the Xeon
5500/5600 series processors that intelligently adjust their voltage and frequency, help take costs
out of IT:
40W 4-core processors use 50% less energy than 80W processors and 69% less than 130W
processors.
60W 6-core processors use 37% less energy than 95W processors and 54% less than 130W
processors.
1.5V DDR3 DIMMs consume 10-15% less energy than 1.8V DDR2 DIMMs used in older servers.
1.35V DDR3 DIMMs consume up to 19% less energy than 1.5V DDR3 DIMMs.
Solid-State Drives consume up to 80% less energy than 2.5-inch HDDs and up to 88% less than
3.5-inch HDDs.
Operating at as much as 94% efficiency, high efficiency power supplies use less energy than
competitive power supplies that average only 70-80% efficiency, and produce less waste heat that
needs to be cooled.
Dynamic fan speeds In the event of a fan failure, the other fans will run faster to compensate until
the failing fan is replaced. Competitive fans must run faster at all times, just in case, wasting power.
Advanced Systems Management Capabilities
Each BladeCenter chassis offers a high level of systems management capabilities that are well-
suited to remote locations as well as to stand-alone environments. Features include the
Advanced Management Module (AMM), Integrated Management Module (IMM), Automatic
Server Restart, Systems Director Active Energy Manager for x86, Wake on LAN
®
support, PXE 2.0
support, text and graphics console redirect, Predictive Failure Analysis, Embedded Dynamic
System Analysis, and IBM Systems Director.
The chassis-based AMM, in combination with the HS22 blade server’s IMM, provides industry-
standard Intelligent Platform Management Interface (IPMI) 2.0-compliant systems
management. The AMM 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
VLAN support
Enhanced authentication and encryption algorithms (RMCP+, SHA-1, AES)
Local update of IMM firmware
Firmware firewall
Support for IPMI v2.0 compliant management software (e.g., xCAT)
Other mandatory and optional IPMI functions in the blades IMM
The IMM, via the management module, alerts IBM Systems 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
