Hyper-V and storage

Hi, i need some advice on storage for using with Hyper-V. SAN is the best solution, but since i dont need SAN and the price is high i was wondering if 2012 R2 Storage Server would be an good alternative?

Hyper-V server with VMs and VMs OS ( VHD files ), 10GBase network card(s)

Storage Server with VMs datadisks ( VHD files ), 10GBase network card(s)

If using 2012 R2 storage server for Hyper-V VMs datadisks, is it possible to run backup from the 2012 R2 storage server OS to backup/restore VHDX files on that server? Does the VHD(X) files need to be fixed size when backups not running from the VMs?

Is this a single server or a cluster? If it's a single server you may just as well use the local disks rather than having a separate server for storage.

You can use Storage Server, or  we prefer to use StarWind iSCSI Software for FREE!

StarWind iSCSI SAN Free Edition
Don't think StarWind cluster is free in which case it's not really any better than local disks.

Here are the answers to your question:

1.  VHD(X) files don't need to be fixed size when backups are not running from the VMs.
2. Starwind (including the free edition) is a very good choice and offers awesome performance and features.
3. You can configure iSCSI targets on your Storage Server without Starwind first, and then compare it both performance/feature wise.
