[CentOS] Old HP Xeon server blade with only SCSI HDD ports & CentOS

[Christian Freund]

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

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?
