ESXi 6.0, and using QNAP for snapshots storage

Hello all,

First, I'm new to this forum and to VMWare so your kindness is appreciated.

Here's the background:

I have 4 servers in different locations that are running ESXi 6.0, two are Dell R220, one HP DL 380 G9, and one is HP DL 160 G9.

The servers were built a few years ago by a previous VoIP vendor and are hosting ShoreTel servers and virtual switches.

The problem is that the vendor selected too small of hard drives and there isn't enough space for snapshots.

We have QNAPs available in each location.

I was wondering if it's possible to use them as storage locations for snapshots?

If so, can I be guide how to do that?

I tried consulting with QNAP support but they weren't helpful.

If more information is required, I will gladly provide it.

Thanks in advance.
