Compaq AlphaServer DS20E Systems
The Compaq AlphaServer DS20E system delivers high
performance for business, technical, and scientific
applications at an affordable price. As a high-capacity
database server, high-performance application server,
Network File System (NFS) server, or Internet server, the
AlphaServer DS20E delivers exceptional value and
investment protection.
Compaq AlphaServer products use the 64-bit Alpha RISC
architecture that supports multiple operating systems:
Tru64 UNIX, OpenVMS, and Linux.

System Overview
The Compaq AlphaServer DS20E uses the third-generation
Alpha 21264 processor. Two speeds are available, the EV67
chip, which runs at 667 MHz and the EV68 chip, which runs at
833 MHz. The switch-based system interconnect exploits the
full potential of these Alpha chips.
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 6
systems and 4 StorageWorks shelves can be installed.
The DS20E system is available with one or two processors.
The system accommodates six hard disks, a floppy diskette
drive, a CD-ROM, and space for one additional 5.25-inch
removable media device. The system supports up to 218.4 GB
of internal storage using 36.4 GB disks.
There are 6 PCI slots, one of which could be used for an ISA
device. Integrated on the system board are controllers for a
SCSI tape device, a diskette, two serial ports, one parallel port,
and the keyboard and mouse.
Three operating systems are supported: Tru64 UNIX,
OpenVMS, and Linux. Customers can order the system that
meets their present application needs; they choose the size of
the system disk, an Ultra3 SCSI adapter, and an Ethernet
adapter. Systems can also be configured in a choice of two
cabinet enclosures: a 67-inch or 79-inch M-series cabinet.
Features and Benefits
• Leadership 64-Bit Architecture
The Alpha 64-bit architecture was introduced with the Alpha
21064 chip in 1992 and now the 21264, builds upon that
proven architecture.
• Performance
The Alpha 21264 chip when combined with a switch-based
interconnect demonstrates its full potential. This switch-based
system provides a memory bandwidth of up to 5.2 Gbytes/sec
(peak) using two 256-bit memory buses running at 83 MHz.
• Reliability and Availability
The AlphaServer DS20E uses the latest technologies to
achieve redundancy, error correction, and fault management.
The balance between simple error detection and error correc-
tion provides high availability at low cost. Hot swappable
disks, fans, and power supplies allow repairs to be done with-
out shutting the system down.
• DS20E Workstation
The pedestal package can also be ordered as a workstation.
