(From the AlphaServer DS25 Technical Summary)
 The
AlphaServer DS25 systems support two Alpha 21264C 1000 MHz CPU chips; up to 16
Gbytes of memory can be installed. Second-level cache is 8 Mbytes per processor.
The switch-based system interconnect exploits the full potential of the Alpha
chip.
The system is available as a pedestal or as a rackmount
system. The components in both are identical; the rackmount
variant is simply rotated to its side. The rackmount system
requires 5U space and can be mounted in a 67- or 79-inch
M-series cabinet along with additional disks. In the largest
cabinet up to six systems and two StorageWorks shelves can
be installed.
The AlphaServer DS25 system is available with one or two
processors. The system accommodates six hard disks or tapes
and a CD-R drive. The system supports up to 876 GB of internal
storage using 146 GB disks. There are six PCI slots - all
support 64-bit options. Four slots run at 66 MHz, and two
run at 33 MHz. Integrated on the system board are dual Ethernet
controllers (10/100 port and a 10/100/1000 port), dual Ultra3
SCSI controllers, and an IDE controller, two serial ports,
one parallel port, and the keyboard and mouse.
Three operating systems are supported: Tru64 UNIX and OpenVMS. Customers can order the system that meets their
present application needs.
