Server details As below.

Performance Specs: Processor: 2x Intel Xeon E5-2697 V3 Dodeca (12) Core 2.7Ghz Memory: 128GB DDR3 (8 x 16GB - DDR4 ) HDD: 10x 2.5" Drive Bays Interface- 41G and 410G Intel Motherboard: X9DRG-HF * Integrated IPMI 2.0 Management

We want setup Open stack OOO with them.

2 Controller 6 Compute (4 Node for SRIOVand 2 node for OVS) under-cloud will be a separate server

As all of the drive have 10-HDD we want to use 2HDD in compute for OS and renaming 8 HDD for Ceph storage.

So question is here Can we use compute as a ceph storage also. Will that cluster will work for enterprise network. how clustering will be happen for Ceph.

if any one have any better suggestion, we will welcome here.

Thanks in Advance

For a production environment I would always recommend to use dedicated servers, mixing services like openstack and ceph is not a good idea. Performance impacts during Ceph recovery can be huge, especially if the compute nodes also run VMs.

As already said, use dedicated servers. Ceph is supposed to be a highly available storage cluster, running other services will have impact on the availability and also on the performance. You can mix ceph services on one host (OSD & MON), but don't mix ceph and other services, you'll regret.
