New Cluster for VMware migration

[admin55]

We are all in on Proxmox. Purchased subscriptions for a 3 host cluster. Question I have is should we stick with iscsi or go NFS?

Current Vmware cluster
3 Dell Hosts with 25gb nics doing MPIO through 2 25g switches
Doing iscsi to an IBM 5200 SAN. This is been flawless for almost 3 years with amazing disk performance and reliability.

We have a new 3 node proxmox cluster setup basically the same way as above.

Question is do we stick with iscsi which we are leaning towards even without thin disk or do we do NFS? Space on the SAN isn't much of a concern even doing thick disks for our VM's

Any insight would be appreciated.

Hi @admin55,

Congratulations on making the move. Either option is fine, frankly. Both protocols have been around for decades. It depends on your requirements, management familiarity, etc. Why not try both? Just create two storage pools and see which one works better for you.

Also, keep in mind that its not about protocol - it is about implementation and infrastructure. You could ask IBM for their recommendation.

I've done this for one of our mid sized clusters, you need to ask a few very important questions. Are you wanting to maintain the same configuration environment of SAN + Shared LUN + VM's with snapshot / etc? Are you wanting to migrate to a different architecture entirely? Are you wanting to sacrifice snapshot and other abstraction support? Each of those answers requires a different solution and those solutions have varying levels of effort and knowledge required.
