4. System Configurations
This chapter briefly describes some of the many configurations that are possible with the
highly modular and scalable SGI 2400 and SGI 2800 server systems.
Overview
No matter which SGI 2400 or 2800 system you have, each configuration contains the
following major hardware:
• CPU Node boards with 64-bit processors
• main memory (which is located on the Node board)
• a Router board(s)
• a BaseIO board (which provides the system I/O ports such as serial, Ethernet, and
SCSI interfaces)
• single-connector assembly (SCA) drive bay(s) for single-ended, ultra SCSI drive
installation
• a drive box (Vault)
The SGI 2400 or 2800 chassis is housed in a rack system that comes with a multimodule
System Controller (MMSC) and display, and also provides cable management hardware
for CrayLink Interconnect and XIO cables.
Note: Additional system modules or individual hardware components can be added to
suit growing computational and I/O requirements.
