Re: [ceph-users] Anybody doing Ceph for OpenStack with OSDs across compute/hypervisor nodes?
Ceph can be quite hard on CPU at times, so I would avoid this unless you have lots of CPU cycles to spare as well. \C - Original Message - From: Blair Bethwaite blair.bethwa...@gmail.com To: ceph-users@lists.ceph.com Sent: Tuesday, 10 December, 2013 10:04:01 AM Subject: [ceph-users] Anybody doing Ceph for OpenStack with OSDs across compute/hypervisor nodes? We're running OpenStack (KVM) with local disk for ephemeral storage. Currently we use local RAID10 arrays of 10k SAS drives, so we're quite rich for IOPS and have 20GE across the board. Some recent patches in OpenStack Havana make it possible to use Ceph RBD as the source of ephemeral VM storage, so I'm interested in the potential for clustered storage across our hypervisors for this purpose.

Any experience out there? I believe Piston converges their storage/compute, they refer to it as a null-tier architecture. http://www.pistoncloud.com/openstack-cloud-software/technology/#storage -- Kyle ___ ceph-users mailing list ceph-users@lists.ceph.com http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
