The hope is to be able to provide scale-out storage, that will be performant enough to use as a primary fs-based data store for research data (right now we mount via NFS on our cluster nodes, may do that with Ceph or perhaps do native cephfs access from the cluster nodes.) Right now I’m still in the “I don’t know what I don’t know” stage :) From: Willem Jan Withagen <w...@digiware.nl<mailto:w...@digiware.nl>> Date: Monday, Jan 28, 2019, 8:11 AM
I'd carefully define the term: "all seems to work well". I'm running several ZFS instances of equal or bigger size, that are specifically tuned (buses, ssds, memory and ARC ) to their usage. And they usually do perform very well. No if you define "work well" as performance close to what you get out of your zfs store.... be careful not to compare pears to lemons. You might need rather beefy HW to get to the ceph-cluster performance at the same level as your ZFS. So you'd better define you PoC target with real expectations. --WjW _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
