Thanks Jan for the reply. It's good to know that Ceph can use extra cpus for throughput. I am wondering if any one in the community has used/experimented with Arm v8 2.5 GHz prosessors instead of Intel E5.

In terms of throughput yes - one OSD may have thousands of threads doing work so it will scale accross multiple clients.
But in terms of latency you are still limited by a throughput of one core, so for database workloads or any type of synchronous or single-threaded IO more cores will be of no help.
