Hi,
I've got a 2 Node Storage only setup, using HDD RAID10 on each Node. Disk performance locally is great, getting around 470MB/s Read/Write (sequenctial).
I have have 2 x 1GB NICs connected on each host, using a cross-over cable. I have 4 x 1GB NICs for iSCSI traffic on each node.
I have 2 Hyper-V Hosts and 2 ESXi Hosts, each with 4 x 1GB NICs for iSCSI.
I know I have a non-reccomended setup, but every installation will be different, so I'm after ideas on what others are using. VM Performance is good, but not as good as I am used to (I've come from running SSDs for Storage).
I can't see any Sync issues, but not really looked into the logs, as things are working. Is there something I can monitor to see if they are struggling with the load?
Should I increase the amount of NICs for Sync?
Should I reduce the amount of NICs for iSCSI (both on Storage Nodes and Hypervisor nodes?
Any other advice would be appreciated, to try and imporve VM Performance. NOTE: At the moment, 10GB is not an option for me, as this is a Dev environment, I want to keep costs low.
Thanks in advance.
