I currently have a Netgear ReadyNAS device I am using for SQL server backups & misc file storage (ISO files, pfsense configs, etc).
I just finished setting up two identical R620 servers with XCP-ng (upgraded from older XenServer 7.1) and would like to implement a high availability setup which requires a shared storage.
Another thing I am starting to do is implement clustering on my Windows servers which require shared storage (right now I am just using the Netgear device for testing)
So the Netgear device has now become a single point of failure for our infrastructure. It is not a big deal for just SQL server backups and misc files because SQL server backups are being sent off site and most of the other stuff is synced to the cloud. But with adding in Windows clustering and wanting to take advantage of shared storage for XCP-ng I am needing a different device.
So right now I am putting together a budget for upgrading to either a dual controller NAS/SAN or a dual device NAS/SAN as well as getting 10Gb equipment.
I am not sure if I could get away with using a SAN for the Windows needs (SQL backups & shared file access for Windows Clustering/ IIS Clustering / SQL Server Clustering). Then just keep the current NAS for ISO files and misc files.
The options on my list so far:
Two Synology devices in HA mode (RS2418+)
Dell dual controller SAN (something a few years old)
I would like to keep the price at $10k or less
I looked into TruNAS but they seemed to have removed their pricing but from what I remember they started at $20k
My current NAS is 5TB and I keep the usage at around 25%
