Re: Fwd: [Ceph-community]Improve Read Performance

[Somnath Roy <Somnath.Roy@xxxxxxxxxxx>]

And what kind of performance are you looking for?

I assume your workload will be small block random read/write?

Btw, without SSD journal write performance will be very bad specially when your cluster is small..

Thanks for your reply.

I intend use Ceph RBD as shared storage for Oracle Database RAC.
My Ceph deployment has 3 nodes with 8 1TB 15k SAS per node, I do not have SSD at the moment, so I design every SAS will be Journal and OSD.

Can you suggest me a way to get highest performance for Oracle Cluster with this deployment?

Many thanks.
