SGI Origin 300
The SGI Origin300 was released October 9, 2001 as a mid-range server for technical computing and media applications. An Origin300 compute node consists of a 2U-high system that contains 2 or 4 64-bit MIPS microprocessors and up to 4GB of local memory.
The Origin300 uses an IP45 mainboard housing the following components:
- 2 or 4 MIPS Microprocessors (with independant secondary cache)
- Four Dual inline memory module (DIMM) slots organized in banks of two
- The Xbridge ASIC that interfaces between the Bedrock ASIC and PCI slots
- The Bedrock hub carrying traffic between the processors, memory and I/O devices
- EEPROM containing the system's Serial ID
- L1 Controller
- Five Voltage Regulation Modules
- Two NUMALink 3 LEDs and Four hearbeat LEDs
The Origin300 was available with 2 or 4 64-bit R14000 processors per compute node in either 500MHz or 600MHz clock speeds.
