Hi Les, we did that this winter in another floor and replaced a complete server-room, containing several Racks full of 1850/1950/2850/2950/R310, except the least all with 2 or more local SCSI-disks and dual power-supply. All that now runs in a virtualized environment on 2+1 R720; we now have 3 R720 replacing 4 racks in another room. This means no air-conditioning, UPS, switches there. Allover it is an average of 31KW lower power-consumption. Now calculating the hardware cost: 60K EUR for servers, storage-upgrade and licenses, and saving 262MWh or 52K EUR per year. So after 14 month of operation the energy-saving pays the hardware. Not speaking of the allover TCO including lower staff-costs and maintenance for the bigger amount of hardware now off. mit freundlichen Grüßen Christian Freund ------------------------------------------- Christian Freund - freund@xxxxxx -----Ursprüngliche Nachricht----- Von: centos-bounces@xxxxxxxxxx [mailto:centos-bounces@xxxxxxxxxx] Im Auftrag von Les Mikesell Gesendet: Montag, 14.

R410 or R610's'll do you. So has anyone done a cost analysis on the point where it is an overall win to replace those old power hogs even if they still work if you consider several years of savings on power/AC/space/time and maybe the possibility of replacing at least 4 old clunkers with VMs on a single new box? Or does no one look at the big picture - like the IRS ending up paying Microsoft for 'custom' support of XP that they've known for years had to go? -- Les Mikesell lesmikesell@xxxxxxxxx _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
