SAN or Server Cluster
Posted on 2014-07-31
Hi Experts. I'm a storage novice but after a year of playing around with a stand alone server (DAS?) running hyper v and a handful of vm's, I'm ready to move up to a more redundant and scalable solution in a production environment. Before making a $30k pitch to the check writers I was hoping to get some advice from you.
You can correct me if I should be looking at another option, but in short, I have a quote for a Powervault MD3220, 6 hard drives, and 2 6gbps SAS controllers and two servers running in HA for about $30,000. I can add another 2 HA servers or 4 non HA later. Another quote is for 3 servers in a cluster is around the same amount.
Other options I have considered in order to reduce sticker shock: 1)go down to one server, for now, on the SAN and live without HA. I would still need a fast restore plan 2) go down to two servers on the cluster and reduce my vm capacity by 1/3.
One trigger for needing to make this move now is that our new office phone system will be running on a Windows 2008 r2 vm, and that needs to be as redundant, or HA, as possible. There will also be a few other vm's related to the phone system that do not need to be HA. Like, I'm ok with 30-60 minutes of downtime on those, although I would like the restore process to be straight forward and well documented so that I'm not the only one that can do it. Other future vm's would be a file server, sql server, terminal/citrix servers, etc. I was going to put exchange on this platform but i think we'll go with a hosted solution instead.
We also have a co-location facility on a 100mbps private line where I may want some replication to occur down the road.
Can you give me some guidance on the value of the SAN appliance versus a server cluster? On this quote we are only using 6 of 18 bays and 4 of 8 connections on the SAS controllers, leaving room for some growth. That seems like a no brainer, but I could also do this a lot cheaper by just setting up a two server cluster, or one server with the best snapshotting/backup tool i can get.
Thanks in advance
