The RS4 is the first server to utilize Sun MicroElectronics' Ultra AXmp
motherboard. The RS4 features up to four 250MHz, 300MHz or 360MHz
UltraSPARC CPUs, up to 6 PCI slots, and a 1.6 GB/sec dual UPA
interconnect. It is equipped with up to 4 GB of main memory with 36 GB
of storage on 2 internal hot swappable Ultra-Wide SCSI hard disks, and
more than 16.2 TB of external storage capacity.
The system is housed in a compact 5U 19-inch rackmount form factor and
runs on Solaris 2.6. In addition, the RS4 is easily monitored with the
DM100, the built-in diagnostic monitor designed by Integrix. Users can
verify critical internal operations, either locally or remotely.
