2/4 Way Interleave ECC Memory
The system includes a main and memory subsystems with four Slot 2
processors and voltage regulators for the processors. The memory
subsystem runs in 100 MHz timing and has a maximum size of up to
4GB.
Six PCI and 1 PCI/ISA shared slots are also incorporated for fast
expandable I/O capabilities.
There are two LVD SCSI (Ultra-2) channels for high performance
storage devices and one Narrow SCSI channel for backup (i.e., tape
drives) or CD-ROM devices.
A high-speed 10/100Mbit Ethernet controller and a PCI VGA device
are also provided.
For more information about the main board see section 3.1.
