We've heard that 1ghz+1GB or so per osd is sufficient. So in your case, around 8 osds. It's likely that you could go even a bit further, since memory is usually more constrained than cpu. Note that memory and processor use during recovery can be considerable higher than during normal operation, so you'll want to test your configuration under recovery. -Sam On Fri, Nov 16, 2012 at 9:40 AM, Snider, Tim <Tim.Snider@xxxxxxxxxx> wrote: > > I'm starting to look at Ceph and was wondering if anyone had a link to more specific OSD server guidelines WRT processor speed and memory requirements. > My candidate server had an Intel processor 2.13 GHz quad core processor and supports up to 24Gb of memory. > I'm wondering about the approximate number of OSDs that this type of processor and memory might support.
