Which storage system to choose for virtualization?

Question

VMware

Good afternoon! What storage system is suitable for virtualization hosting on VMWARE, etc.? You also need SSD cache support, the performance should be strong by itself. The initial volume is 150 TB approximately. Need support for remote replication. It would be nice to have many (16) FC ports to save on the switch.

Answer 1

Wow, why do you need all this? Install CEPH on multiple servers and you'll be happy. In a CEPH cluster, you make a network for 10Gb inside and out.
In total, for your volume, I would do this:
5-6 servers of 8-12 disks on SATA 4 TB + SSD, with 64 GB of memory, 2x CPU Xeon E5-2620v4.
Approximate price of a configuration with disks (8x SATA 4TB + 4x SSD 1Tb) ~ 630Kr
Plus a 10Gb switch ~ 100Kr
Total: 3250 kilorubles.
At the same time, you will get a very functional storage for virtual machines! Caching on SSD and unkilled system! Yes, to expand - by purchasing new servers in the cluster (!). Well, about VmWare, I would look towards KVM.
PS. The system was considered based on "Server Supermicro SSG-6028R-E1CR12T"
P.P.S. We have about the same thing, the total amount of ceph is ~ 120 terabytes.

Answer 2

Recently purchased several OceanStore 5500 v5, 140TB on SSD + spindle drives. Synchronous replication works between storage systems via FC (you need a Hyper-Metro license), they tested it, it seems not bad. Standardly there are 4 FC ports, but there are slots for expansion, probably up to 16 can be increased. IOPS was not measured, I think they will give out 25 SSDs in full :)
