threshold or if a system component fails, the IMM lights LEDs to help you diagnose the problem, records the error in the IMM event log, and alerts you to the problem. Optionally, the IMM also provides a virtual presence capability for remote server management capabilities. The IMM provides remote server management through industry-standard interfaces:

–Intelligent Platform Management Interface (IPMI) version 2.0

–Simple Network Management Protocol (SNMP) version 3

–Common Information Model (CIM)

–Web browser (For more information, see “Using the integrated management module” on page 104.)

v IBM Systems Director

IBM Systems Director is a platform-management foundation that streamlines the way you manage physical and virtual systems in a heterogeneous environment. By using industry standards, IBM Systems Director supports multiple operating systems and virtualization technologies for IBM and non-IBM x86 platforms. For more information, see the documentation on the IBM Systems Director DVD and “IBM Systems Director” on page 12.

vIBM Electronic Service Agent

IBM Electronic Service Agent is a software tool that monitors the server for hardware error events and automatically submits electronic service requests to IBM service and support. Also, it can collect and transmit system configuration information on a scheduled basis so that the information is available to you and your support representative. It uses minimal system resources, is available free of charge, and can be downloaded from the web. For more information and to download Electronic Service Agent, go to http://www.ibm.com/support/ electronic/.

vIBM X-Architecture®technology

IBM X-Architecture technology combines proven, innovative IBM designs to make your x86-processor-based server powerful, scalable, and reliable. For more information, see http://www.ibm.com/servers/eserver/xseries/xarchitecture/ enterprise/index.html.

vLarge system-memory capacity

The server supports up to 1 TB of system memory. The memory controller supports error correcting code (ECC) for up to 64 industry-standard PC3-10600, 240-pin, registered, double-data-rate (DDR) III, synchronous dynamic random access memory (SDRAM) dual inline memory modules (DIMMs). The optional 32-DIMM IBM MAX5 for System x memory expansion module is available for purchase and provides up to 512 GB of additional memory. For more information about the memory expansion module, see “IBM MAX5 for System x memory expansion module” on page 21.

vMemory ProteXion

The Memory ProteXion feature provides the equivalent of a hot-spare drive in a RAID array. It is based in the memory controller, and it enables the server to sense when a chip on a DIMM has failed and to route the data around the failed chip.

vMemory Sparing

The server supports memory sparing. Memory sparing reserves memory capacity for failover in the event of a DIMM failure, and the reserved capacity is subtracted from the total available memory. Memory sparing provides less redundancy than memory mirroring does. If a predetermined threshold of correctable errors is reached, the contents of the failing DIMM are copied to the spare memory, and the failing DIMM or rank is disabled. To enable memory
