In order to put control of processor power-saving features at the fingertips of administrators, IBM

developed IBM Systems Director Active Energy Manager. Active Energy Manager 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 helps you 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,

Active Energy Manager (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 Systems 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 HS22

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-

level tasks remotely that would otherwise require a visit to each system. These tasks may include

such things as formatting a hard disk drive, updating system firmware, or deploying a Windows or

Linux operating system.

Predictive Failure Analysis (PFA) enables the MM/AMM and the IMM to detect impending

failure of supported components (processors; memory; expansion cards; switch, blower and

power supplies; and hard disk drives) before actual failure, and alert the administrator through

IBM Systems Director. This gives you the ability to replace the failing component before it fails,

resulting in increased uptime.

Embedded Dynamic System Analysis (DSA) feature collects and analyzes system information

to aid in diagnosing problems. The diagnostic programs collect the following information:

• System configuration

• Network interfaces and settings

• Installed hardware

• Service processor status and configuration

• Vital product data, firmware, and BIOS configuration

• Hard disk drive health

• RAID controller configuration

• Event logs for ServeRAID controllers and service processors

The diagnostic programs create a merged log that includes events from all collected logs. The

information is collected into a file that you can send to IBM service and support. Additionally, you

can view the information locally through a generated text report file, or you can copy the log to

removable media and view the log from a Web browser.

IBM Systems Director software for advanced workgroup management is included with the

server. IBM Systems Director comes with a portfolio of tools, including Active Energy Manager,

Service and Support Manager, and other tools. System Availability (a no-charge download) and

Capacity Manager (sold separately) are available as add-ons for additional server management

and increased availability. IBM Systems Director provides a single uniform graphical interface for

all of these systems management functions.

IBM Systems Director enables you to customize thresholds and monitor system components (for

things like temperature, voltage regulation, etc.) to help maximize uptime.
