Introducing the SGI 2400 and 2800 Server Systems

The SGI 2400 and 2800 rackmount servers provide a highly configurable system
architecture that is available in a single rackmount or multirack setup. Each rackmount
system consists of 2 to 16 CPUs, 64 MB to 32 GB of main memory and can provide a wide
variety of I/O interfaces (see Figure 1-1). The SGI 2400 server system uses up to four
racks (64 CPUs) but does not use a metarouter. The SGI 2800 multiple rack (or multirack)
metarouter configuration has up to 256 processors and up to 512 GB of main memory (see
Figure 1-2 and Figure 1-3).
The SGI 2400 or 2800 servers are ideal for evolving applications requiring expansion
capability as requirements grow. Some of the server's features include:
• significantly lower entry system costs (with pay-as-you-grow expandability)
• support of a large number of processors (up to 256)
• high bandwidth I/O connectivity
• higher total memory capacity (up to 512 GB of main memory)
• optional connectivity to third-party peripheral connector interface (PCI) boards
• superscalar 64-bit CPUs (two on each Node board) support advanced memory
latency tolerance features such as out-of-order execution and advanced branch
prediction to address real-world application demands
• large variety of peripheral connectivity options
• XIO boards providing additional I/O, mass storage connections, and graphics
capabilities
