NEC (Yonezawa) Crusoe Server CS56
The NEC CS56 server
uses a TM5600 Crusoe processor running the Linux 6.5 Secure Server Edition while
consuming less than 20 Watts of power. The unit has no fan on the processor (low
noise signature), and even comes with a built-in UPS and optional RAID.
Measuring 145 x 240 x 220mm (W/D/H) and weighing in at 5-6Kg, the small server
includes an internal power supply and can be placed into a 19" wide rack in 2
and 3 unit wide configurations if desired.
The CS56 server in the most advanced version contains a
600Mhz TM5600 Crusoe processor coupled with the Ali M1535 Super South Bridge,
192MB SO-DIMM memory, an ATI-mobility graphics chipset, 40Gb (x2 for RAID) hard
drives, optional CD-ROM, 1 serial, 2 USB, 1 parallel, 2 PCI, 2 PS/2, 1VGA
and dual RJ-45 ports. Internally there are up to 2 PCI sockets, and room
for compact flash storage.
Looking at the specs, the CS56 appears to be geared more
toward the SOHO and office server application as opposed to ISP-class web
serving. While NEC does mention the compatibility of the units in 19" racks,
doing so in an ISP or IDC would take up valuable rack space and be quite costly.
The built-in UPS is a very neat feature to have in a
server, and as the documentation explains it, if there is a interruption in the
main supply, the unit will continue operation for a few minutes and then
automatically shut down in a safe manner. While the CS56 comes with the Linux
OS, it can be loaded with Windows 2000.
The unit is beginning mass production and will retail for 138,000 Yen ($1100USD) in OEM quantities. NEC expect to sell around 5000 units this year.
