I have used NAS devices as backup targets for SQL server databases. I have used them as file shares which are mapped to servers holding databases. Thing is that our current NAS supports iSCSI protocol and was wondering if I can use NAS LUNs (mapped as drives) in the SQL server virtual servers and take advantage of the protocol? Anyone who has tried this before or know about some difficulties/deficiencies using this method. Thanks.

    Be mindful to follow iSCSI best practices, even if it's just a NAS device instead of a SAN. You'll want to have these going to a different NIC in a different subnet/network with preferred direct connect in this scenario but if going through a router ensure it has jumbo frames, the right amount of ram, and so fourth. In that scenario you could even use it as local storage. – Ali Razeghi Jan 27 '17 at 20:33

Drive mapped iSCSI targets work perfectly for SQL Server backup destinations.

Map the iSCSI target into your VM as a drive, assign a drive letter inside the VM, and just do normal backups as you would to any other target.

I use that exact process for my clustered SQL Servers.

    Thank you Max, those are the exact words going around my head about how to do the process, just needed some confirmation based on experience and you did it. – Humberto Castellon Jan 27 '17 at 21:09
