A few years back we grabbed a budget for vcenter and a dual network storage server to make our VMs somewhat fault tolerant. After buying the license, we only had enough left to buy 2 dell servers and run freenas with data replication and virtual IP. If I remember right the storage servers use 15k sas drive in raid 10. Pretty sure this is set up as a NFS datastore. It was cool seeing the failover happen with success for the first time. I wouldn’t say I trust it though.
This cheap storage solution is networked 1gbe to a switch and the switch is 1 gig to the 2 vsphere. We originally this for mostly management servers that send us alerts and stuff. We now run windows servers and pbx systems. Noticing when I use the network data store, tasks run slower than local datastore. I get lag when requesting files on vms etc.
Vsphere hosts are 3 dell r610s with 10k sas drives. Is it possible to buy a system that would provide maybe 2 to 4TB of network storage that would respond with less latency than a local datatore? We are going to add virtual servers that recieve streaming telemetry and sflow and I dont want these servers to have a bottleneck on their storage.
Basically I would like some flash network storage that doesn’t suck and is fault tolerant for under 10k. Any suggestions please?
