AlphaServer DS20L system overview


(from the AlphaServer DS20L Technical Summary)
The AlphaServer DS20L systems have two Alpha 21264B 833 MHz CPU chips.
Up to 2 Gbytes of memory can be installed. Second-level cache is 4
Mbytes per processor. The switchbased system interconnect exploits the
full potential of the Alpha chip.

*ds20l_fl_small.jpg* The system measures 17.5 x 20.5 x 1.75 inches
(1U) and can be rackmounted in a 79- or 67-inch M-series cabinet. In the
79-inch cabinet up to 40 systems can be installed, or if more storage is
desired, there can be up to six StorageWorks shelves per cabinet. A
rackmount slide kit is mandatory with each system in a cabinet.

Each system has two drive bays. One is for the system disk drive, which
can be either IDE (20 or 40 GB disk) or SCSI (18.2, 36.4, or 72.8 GB
disk). The other can hold an optional CD-ROM.

Two 10/100 fast Ethernet controllers and an Ultra3 SCSI controller are
integrated into the system. For expansion there are two 64-bit, 33 MHz
PCI slots (2/3 length). Two serial ports and a bi-directional enhanced
parallel port are also available.

Systems can be purchased with the Tru64 UNIX operating system installed,
or they can be purchased without any operating system, allowing
customers to install Linux.
