I finally got ESXi working on my server, and multiple virtual machines... but now, of course I need more storage space.

From what I am reading I am able to attach a NAS device? They seem to be much cheaper than SANS.... is there any advice as to what type I should get? How should it be configured?

thanks so much

As fast disks as possible(1 SATA/VM for decent speed) - 2 vms / SAS disk(might get a bit slow tough)

NFS or iSCSI support(ESX supports NFS, iSCSI and FibreChannel as i recall)

4-8 disk nases is what I would look at.

I would check out the Drobo NAS as it has support for iSCSI and lotsa slots for disks.

We have a NAS setup with NFS configured with ESX v4 and running VMs. If you are going down this route, here are a few tips:

  • Have redundant NICs for NFS traffic and a pretty good backbone back into your NAS (we use dedicated gigE). You can also configure a vSphere host with a dedicated NIC for storage traffic.

  • vSphere gets finicky with misbehaving mounts. If you lose connectivity to a NFS share for whatever reason, the mounts may go offline and the only way to bring them back online is by a host reboot, recreating the mount from scratch, or running some command line Vmware scripts on the console - could not get do it from the GUI.

This post has some interesting discussions on parameter settings for ESX 3.5 and NFS mounts - you may want to check if some of these are applicable.

Other than that, works pretty well for hosting VMs, snapshots and vmotion.

Hope that helps, Bruno.
