I have setup a SAN to work with proxmox. The SAN uses multipathing over 4 dedicated NICS.
I have a Dell MD3200 connected to a high speed switch. The configuration is using Jumbo Frames over a 1 Gb line.
I'm able to build and migrate servers on the SAN I setup and built, and functionally, everything is working well.
I'm new to working with SANs, and I want to test the performance of the VMs with the SAN.
I did a simple test by writing a 4 GB server on a virtual machine that is stored on the SAN.
Using dd, I get:
Is there a better way to test the performance, and what sort of numbers should I be getting?
thanks.
