the ability to add more tools to the bootable image and to automatically download the bootable
environment if needed. Bootable Media Creator allows you to create bootable CDs, DVD, and
USB keys for updates customized to your systems.
IBM developed IBM Systems Director Active Energy Manager to put control of system power-
saving features at the fingertips of administrators. Active Energy Manager is designed to take
advantage of new features, such as monitoring power usage and balancing the performance of
the system according to available power input. It provides the ability to plan and predict power
consumption based on your hardware configuration. It also helps enable 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, then adding up the total power draw and tracking the usage. It also includes power
management features to help administrators manage or reduce power usage.
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.
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 enables software such as the optional 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.
Text Console Redirection support allows the administrator to remotely view x3550 text
messages over serial or LAN. An optional upgrade to the Virtual Media Key adds graphical
console redirection.
Predictive Failure Analysis (PFA) is designed to allow the system to detect impending failure of
supported components (processors, memory, HDDs, voltage regulator modules (VRMs), power
supplies and fans) 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.
IBM Systems Director software for advanced workgroup management is included with the x3550
M3. IBM Systems Director comes with a portfolio of tools, including IBM Systems Director Active
Energy Manager, Service and Support Manager, and others. Others 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.
Key Options
IBM options for System x servers help you take your servers to a
higher level
You know can rely on System x options to supply a complete solution for your business needs.
Options help you create an optimized server system to meet your data protection, storage and
availability needs. Every IBM option is designed and tested for peak performance and flexibility,
helping to maximize your return on investment. The combination of System x servers and options
lets you keep your fingers on the pulse of your e-business.
Processors —Intel Xeon processors provide high clock rates, 4 or 6 cores, and advanced
features for performance, availability and power management. Large cache size, combined with
fast 1333MHz, 1066MHz or 800MHz memory access and an integrated memory controller reduce
memory latency and facilitate the movement of data. (Note: System performance depends not
only on the number of processors in the server but also on the frequency and functionality of each
processor.) Adding a second processor may be a cost-effective way to achieve significant
performance improvements.
Memory — Memory is a major factor in systems application performance. Adding more memory
to a System x server is one of the most effective ways to increase application performance. For
best performance in a server with a 4-core processor, there should be twice as much memory as
for a 2-core processor. A 6-core processor should have three times as much memory as a 2-core
processor.
