Hi all,
I am running UnRaid on a QNAP TVS-471 with 20TB x 6 - Seagate Exos x20. I'm not running ZFS on Unraid, I'm using the storage in Unraid to store the disks on Proxmox Containers & VMs via NFS. I'm also mounting the NFS shares into the VMs to write files in other shares, I noticed that the performance is incredibly slow which causes the VMs on Proxmox to run slow or at times not boot well.
I reckon there is a bottleneck somewhere but not sure how to diagnose it properly. Here is some additional information.
3 Nodes on Proxmox running HA
Dell OptiPlex Micro Form Factor 7010
i7-12700
64 GiB DDR4
1TB NVMe
Storage Server
QNAP TVS-471XT
UnRaid 6.12.8
i7-8700T CPU
64 GiB DDR4
20TB x 6 - Seagate Exos x20 - (1 Parity)
2TB NVMe for Cache
The 3 nodes and Storage are connected to a Unifi 1G Switch.
I'm sure there are optimizations that I need to do but not sure where to start.
Edit - Writing this down, I can see that the Optiplex standard NIC and the Switch could potentially be the bottleneck, I wonder if I upgraded the Nics to a 10 gig and get a unifi switch aggregator or a smaller 10 gig switch for the devices if that would resolve it? Before that I'd like to confirm if there any other optimizations that I need to do
