Our staple box is the SunFire X2100 M2, which sells for about 400 EUR sans VAT (kit has 1.8 GHz dual-core Opteron, 512 MByte DDR2, no disk). I've measured 115 W at idle with 2x TByte SATA disk and 8 GByte DDR2 RAM which is even better than what Sun says http://www.sun.com/servers/entry/x2100/M2calc/index.jsp#calc > The single-socket 2U nodes that I buy cost the same as our developer > desktops, which have a somewhat expensive case in order to be quiet. > Since he's putting these into a hosting facility, it's likely that > having 1U boxes doesn't gain him anything... the limit is generally > power, not space. And 2U boxes are quieter and more reliable. _______________________________________________ Beowulf mailing list, Beowulf@beowulf.org To change your subscription (digest mode or unsubscribe) visit http://www.beowulf.org/mailman/listinfo/beowulf
