Hi all,
So far, I’ve been running Windows Server 2022 Enterprise as an Hypervisor, which then has several SCSI mounts to my TrueNAS Core box.
Both servers are using a 10Gbs link, however, I have the option to increase this if I link the dual port nics. I haven’t done it so far, since I don’t know 100% if it would take really advantage of it.
The VMs are a mix between Windows VMs and Ubuntu (to run Docker) and something I’ve always tried is to have storage be transparent to the VMs, so that they see the storage as a normal disk.
The performance I’m getting is not great, but usable considering its all spining rust. (Raid 10, 4 drives is what I’m using for the VMs).
What I’m looking is for suggestions and perspective, regarding what Hypervisor to use, which will provide a good performance using remote storage on TrueNAS and a reliable and low overhead snapshot system?
Right now, doing snapshots from TrueNAS side doesn’t really work properly, since TrueNAS just sees block storage and can make a snapshot in a moment, which causes some data to be lost if restored from there. This is a software limitation that is using this storage I believe.
Also, any tips on how to test, tune and improve the pools performance for this purpose?
Thank you.
