Hi All, I've been looking at Ceph as a storage back end. I'm running a research cluster and while people need to use it and want it 24x7 I don't need as many nines as a commercial customer facing service does so I think I'm OK with the current maturity level as far as that goes, but I have less of a sense of how far along performance is.
My OpenStack deployment is 768 cores across 64 physical hosts which I'd like to double in the next 12 months. What it's used for is widely varying and hard to classify some uses are hundreds of tiny nodes others are looking to monopolize the biggest physical system they can get. I think most really heavy IO currently goes to our NAS servers rather than through nova-volumes but that could change. Anyone using ceph at that scale (or preferably larger)? Does it keep up if you keep throwing hardware at it? My proof of concept ceph cluster on crappy salvaged hardware has proved the concept to me but has (unsurprisingly) crappy salvaged performance. Trying to get a sense of what performance expectations I should have given decent hardware before I decide if I should buy decent hardware for it... Thanks, -Jon _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
