Re: [Xen-users] Capacity planning

["Angel Lopez" <angel@xxxxxxxxxx>]

Hi Tim,

Well I wasn't thinking in a specific case, instead I was looking for some
guidelines to calculate xen servers capacity. For example, given 5 or 6
Linux servers and 2 or three windows servers, how to get their resources
use profile using tools like sar, top, vmstat, iostat... and with this
data how to plan the capacity in the xen servers (cores, memory, disk I/O,
network bandwidth...).

I know that each case is different and must be studied, but maybe people
with experience in server consolidation can give some guidelines to walk
in the right way.

Thanks.
