My organization currently has a physical server with 256gb RAM and 2 x 4tb internal Intel P4500 SSD cards. It's a Hyper-V host and all of the VMs live on the internal SSD cards. Performance is great but I'm exploring options for expanding our storage.
Rather than having all of the storage within the server box, one obvious alternative is a SAN. But the SAN configurations I'm looking at are over $30,000. Boooo.
It seems like NAS devices are getting a lot more powerful, robust and (with Flash drives) faster.
So my question: Is it feasible to load up a Synology with Solid State drives (or a hybrid combination), connect it directly to the server and then run all of the VMs off of there? And would it be best to connect using dual 10GbE direct Ethernet connections and iSCSI?
I fully understand a NAS is not a SAN. I am trying to consider in-between solutions. I know how my VMs run with internal storage. I know how my VMs will run on a SAN. But what if I ran all of my VMs on a NAS? (the SAN solution I am looking at blows away my current solution as far as IOPS so I might even say a SAN is overkill. With my current solution we are not experiencing any latency or speed issues)
Another question - if this is feasible, then would I be able to connect TWO or THREE servers to the NAS and have them all share the same NAS volume?
White papers or actual real-world examples would be great.
