v IBM ServerGuide™ Setup and Installation CD The ServerGuide Setup and Installation CD that comes with your blade server provides programs to help you set up your server and install a 32-bit Windows operating system. The ServerGuide program detects installed hardware options and provides the correct configuration programs and device drivers. For more information about the ServerGuide Setup and Installation CD, see "Using the ServerGuide Setup and Installation CD" on page 46. v Impressive performance using the latest microprocessor technology Your blade server supports up to two Intel Xeon microprocessors. The blade server comes with at least one microprocessor installed; you can install an additional microprocessor to further enhance performance and symmetric multiprocessing (SMP) capability. v Large system memory The memory bus in your blade server supports up to 8 GB of system memory. The memory controller provides support for up to four industry-standard 2.5 V, 184-pin, double-data-rate (DDR), PC2100, registered synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC) DIMMs. For the most current list of supported DIMMs, see the ServerProven® list at http://www.ibm.com/pc/us/compat/. 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. v Integrated network environment support Your blade server comes with two integrated Gigabit Ethernet controllers. Each Ethernet controller has an interface for connecting to 10/100/1000-Mbps networks through an Ethernet-compatible switch module on the BladeCenter unit. The blade server automatically selects between 10BASE-T and 100/1000BASE-TX environments. Each controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). The controllers support Wake on LAN® technology. v I/O expansion The blade server comes with two connectors on the system board for an optional I/O expansion card, such as the BladeCenter Fibre Channel Expansion Card, for adding more network communication capabilities to the blade server. Reliability, availability, and serviceability features Three of the most important features in server design are reliability, availability, and serviceability (RAS). These RAS features help to ensure the integrity of the data stored on the blade server; that the blade server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience. The blade server has the following RAS features: v Advanced Configuration and Power Interface (ACPI) v Automatic error retry or recovery v Automatic server restart v Built-in monitoring for temperature, voltage, hard disk drives, and flash drives v Chipkill memory for DIMMs with a capacity of 512 MB or greater v Customer-upgradeable basic input/output system (BIOS) code Chapter 1.
