With a traditional bus design, the processors, memory, and I/O modules share the bus. As the number of bus users increases, the transactions interfere with one another, increasing latency and decreasing aggregate bandwidth. With a switch-based system, speed is maintained and little degradation in performance occurs as the number of CPUs, memory, and I/O users increases. Features ======== Up to two CPUs, based on the EV68 Alpha chip 200 pin memory DIMMs (up to 16 with a minimum of 4) I/O board with up to six 64 bit PCI slots: Four hot swap PCI slots with two at 66 MHz (3.3 V) and two at 33 MHz (5.0 V). PCI slot 1 is card only and is hot-swappable. CD-ROM r/w drive Two half-height or one full-height removable media bays One storage disk cages that house up to six 1 inch universal drives per cage Up to three power supplies, offering N+1 power A 25 pin parallel port, two 9 pin serial ports, mouse and keyboard ports, and one MMJ connector for a local console terminal An operator control panel with a 16 character back-lit display and a Power button, Halt button, and Reset button _Top of page_ ----------------------------------------------------------------------------
