Separate disk sets for high IO?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Still relatively new to ceph, but have been tinkering for a few weeks now.

If I'm reading the various docs correctly, then any RBD in a particular ceph cluster, will be distributed across ALL OSDs, ALL the time.
There is no way to designate a particular set of disks, AKA OSDs, to be a high performance group, and allocate certain RBDs to only use that set of disks.
Pools, only control things like the replication count, and number of placement groups.

I'd have to set up a whole new ceph cluster for the type of behavior I want.

Am I correct?
