Its configuration is as follows: SuperMicro P6DNF multiprocessor motherboard The motherboard has on it: Natoma chipset 5 PCI slots 4 ISA slots Two CPU sockets 8 SIMM slots 2 serial ports 1 parallel port 2 IDE interfaces One 200MHz P6 CPU ("Pentium Pro") w/512K L2 cache 1GB of main memory (8 * 128MB 60ns EDO SIMMs) 1 Adaptec AHA-3940 PCI dual-channel narrow FastSCSI controller 1 Adaptec AHA-3940UW PCI dual-channel wide UltraSCSI controller 1 Intel Pro/100B PCI 100Mbps Fast Ethernet controller 1 StorQuest ISA SVGA adapter 14 4.3GB fast-narrow SCSI drives (Quantum, Seagate) 9 9.1GB ultra-wide SCSI drives (Micropolis, Quantum) Rack mounted color SVGA monitor The disk drives are housed in 3 industrial rack mount chassis made by Kingston Technologies. Each drive array is connected to its own Adaptec SCSI channel. The IDE interfaces on the motherboard aren't currently being used. Our connection to the Internet is via 100Mbps Fast Ethernet that connects to core routers which in turn connect to most of the major interchange points on the Internet via multiple DS3 (45Mbps) and OC3 (155Mbps) circuits. Wcarchive is physically located at the CRL Network Operations Center in downtown San Francisco. Each month, more than 1 million people visit wcarchive - sending out to them more than 7 terabytes of files (as of November, 1997), with the only limit being the Internet backbone(s). Wcarchive is the biggest, fastest, busiest FTP archive in the world. [snip] [/quote]help
