I recently built a dual E5-2670 Proxmox host after discovering how affordable they had become. I purchased many of the parts from the suggestions of users in the great deals forum. This is really my first foray into virtualization so I am still learning how to address some issues.
The host has:
-Intel S2600cp
-2x E5-2670
-128GB RAM
-2x 256GB SSD in mirrored ZFS vdev (Crucial MX100, Samsung pull from Lenovo T510, unsure of model), connected to the onboard SATA ports for VM
-Intel RMS25KB080 cross flashed with LSI9205-83 IT firmware
-- 2x 2TB + 2x 6TB in mirrored ZFS vdevs for data attached the the Intel card
Last night, I noticed IO delay in the 7-10% range and some of my VMs slowed down considerably. I run about 8 containers and 2 VMs, all using the defaults or suggested best practices by Proxmox.
I ran pveperf on the two pools and got the numbers below:
Are these numbers normal? Can they be improved? What should I look into to improve performance?
