What your IBM blade server offers Your blade server is designed to take advantage of advancements in memory management and data storage. Your blade server includes: v IBM Director IBM Director is a workgroup-hardware-management tool that you can use to centrally manage servers. For more information, see the IBM Director documentation on the IBM Director CD. v IBM PowerPC® 970 microarchitecture IBM PowerPC 970 microarchitecture technology leverages proven innovative IBM technologies to build powerful, scalable, reliable IBM-processor-based servers. PowerPC 970 microarchitecture technology includes features such as light path diagnostics, Predictive Failure Analysis (PFA), and Advanced System Management.1 v Microprocessor technology Your blade server supports two IBM PowerPC 970 microprocessors and comes with two microprocessors installed. Together, these two microprocessors enhance performance. With two microprocessors, your blade server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. To use SMP, obtain an SMP-capable operating system. For a list of supported operating systems and other options, go to http://www.ibm.com/servers/eserver/serverproven/compat/us/. v Integrated network environment support Your blade server comes with one integrated dual-port Gigabit Ethernet controller. Each Ethernet controller port has an interface for connecting to 10/100/1000-Mbps networks through an Ethernet-compatible switch module on the BladeCenter unit. The switch module automatically selects between 10BASE-T and 100/1000BASE-TX environments. Each controller port provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). The controller supports Wake on LAN® technology. v I/O expansion Your blade server comes with two connectors on the system board for an optional I/O expansion card for adding more network communication capabilities to the blade server. v System memory The memory controller provides support for up to four industry-standard 2.5 V, 184-pin, double-data-rate (DDR), PC2700, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) dual inline memory modules (DIMMs). For the most current list of supported DIMMs, see the ServerProven® list at http://www.ibm.com/servers/eserver/serverproven/compat/ us/. For more information, see "Installing memory modules" on page 24. v Light path diagnostics The light path diagnostics feature provides light-emitting diodes (LEDs) to assist in isolating problems with the blade server. An LED on the blade-server control panel is lit if an unusual condition or a problem occurs. If this happens, you can look at the LEDs on the system board to locate the source of the problem. For more information, see "Light path diagnostics overview" on page 80. 1.
