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 management software, such as the optional

Tivoli Provisioning Manager for OS Deployment, 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 x3620 M3 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 (memory, HDDs, and the onboard battery) 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 x3620

M3. IBM Systems Director comes with a portfolio of tools, including IBM Systems Director Active

Energy Manager

™

, Service and Support Manager, and others. Other tools 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 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 to 6 cores, 64-bit extensions, 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.

Hard Disk Drives — IBM hard disk drives help you improve the transaction and cost performance of

your System x servers. The choice of hard disk drives can be a critical aspect of maximizing the I/O

throughput of the system. 3.5-inch SAS hard disk drives are available for the x3620 M3 with

capacities of up to 600GB at 15,000 RPMs. 3.5-inch SATA HDDs are available in capacities up to

2TB at 7,200 RPMs.

Power Supply — The optional second power supply for the x3620 M3 enables redundancy for hot-

swap power. In addition, its 92%-efficient design helps lower your energy bill for power and cooling.

Virtual Media Key — The x3620 M3 includes a plethora of systems management features built-in;

however, sometimes additional management capability is needed. In those situations, the Virtual

Media Key not only offers powerful new features, it does so without taking up a valuable PCIe
