Getting Started With Your System 3System FeaturesThe major hardware and software features of your system include:• Two or four dual-core AMD Opteron™ 8000 Series processors.• A minimum of 2 GB (dual-processor systems) or 4 GB (four-processor systems) of 667-MHz registeredDDR-II memory modules. Memory is upgradable to a maximum of 64 GB (four-processor systems)by installing combinations of 512-MB, 1-GB, 2-GB, or 4-GB memory modules in the sixteen memorymodule sockets on the system board. (128 GB of memory will be supported when 8 GB memorymodules are available.)• Support for up to five 3.5-inch hot-plug SAS hard drives.• An optional internal 1.44-MB, 3.5-inch diskette drive.• An optional internal slim-line optical drive.• An optional external USB diskette drive.• An optional external USB optical drive.• Two hot-pluggable, 1570-W power supplies in an 1 + 1 redundant configuration. The power suppliessupport an input voltage range of 100 V to 208 V.• Four hot-pluggable system cooling fans.The system board includes the following features:• Two x8 lane-width PCI-Express (PCIe) expansion slots and six x4 lane-width PCIe slots.(One x4 lane-width slot is occupied by the SAS controller card.) Four expansion slots (two x8 slotsand two x4 slots) support full-length expansion cards.• Two integrated Gb Ethernet NICs, capable of supporting 10-Mbps, 100-Mbps, and 1000-Mbps datarates. Each NIC also supports TCP/IP offload engine (TOE) functionality.• Four USB 2.0-compliant connectors (two on the front panel and two on the back panel), capableof supporting a diskette drive, an optical drive, a keyboard, a mouse, or a USB flash drive.• Systems management circuitry that monitors operation of the system fans as well as critical systemvoltages and temperatures. The systems management circuitry works in conjunction with the systemsmanagement software.• Standard Baseboard Management Controller (BMC) with serial access.• An optional remote access controller (RAC) card for remote systems management.• An integrated VGA-compatible video subsystem based on an integrated ATI RN50 33-MHz PCIvideo controller. The video subsystem includes 16 MB of graphics memory and supports various 2Dgraphics video modes. Maximum resolution is 1600x1280 with 65,536 colors. (When the optionalRAC is installed, the integrated video subsystem is disabled and the video controller on the RAC isused instead.)
