The previous was a local HDD (2TB, 7200rpm) on the management server with
an NFS share, then mounted to cloudstack over NFS.
New storage is Raid-z2, 1G between hosts and to NAS, ping seems to take
0.05-0.3 ms between hosts as well as to the NAS.

Pierre, What was the "old" storage? Was it local or NAS? This question is to
compare against your new storage. How do you have the 8x8TB disks
configured? A pool of mirrors? RAID-Z2? Are you 1G or 10G or faster between the
hosts and the NAS?MikeSent from my Galaxy

Hi all,
We're working on upgrading our storage solution to a proper network
attached storage.
Before this, we had an NFS share on some mounted disks on the management
server. Our new setup is a NAS running TrueNAS (zfs) with 64 GB ram and
Just enjoying the subject, I'm curious about what we can reach in disk
performance when using NFS primary storage. We have two infrastructures
with different purposes, one to instantiate normal VMs and other to be used
by VMs involved with scientific researches running simulations, AI
training,
Big thanks for all the suggestions :)
We've ordered some NVME SSDs for write caching, this is something we missed
when setting up the machine originally.
Sounds like the setup should work other than that.
Best,

The performance will be horrible if you do not have a ZIL in your pool and use
NFS. You can add this at any time but you need to make sure it is a very fast,
low latency SSD or NVME. Once you have this in the pool, you will see a
significant performance increase.

Hi Pierre,
In the past we try a similar solution than you to increase the
realiability of storages using ZFS (in our case was ubuntu). ZFS borns
to be safe, so when you write a block the system don't write other
block until this block confirms that is ok, so it slow.
In our case, we can
