Hi,
Trying to make the most of a limited budget. I need fast I/O for operations under 4MB, and high availability of VMs in an Ovirt cluster.
I Have 3 nodes running Ovirt and want to rebuild them with hardware for converging storage.
Should I use 2 960GB SSDs in RAID1 in each node, replica 3?
Or can I get away with 1 larger SSD per node, JBOD, replica 3?
Is a flash-backed Raid required for JBOD, and should it be 1gb, 2, or 4gb flash?
Storage network will be 10gbe.
Enterprise SSDs and Flash-backed raid is very expensive, so I want to ensure the investment will provide best value in terms of capacity, performance, and availability.
Thanks,
Vincent
