We currently added a shelf to the VMware server until we can get over this issue. We did try the 10G tunables and nothing worked out there. We tried just running the 10G network cable right from the ESX host to the arrays so we feel its not network. Should not take an hour to copy 2 100GB VMs via vMotion from one iSCSI ZVOL to another on the same POOL. Ok we're back with slow performance on this ZVOL. The only focus right now is our iSCSI VMware pools.ġ of 3 Supermicro CSE-836 w/BPN-SAS2-EL1 Cases holds the system board Mirror 460K and a couple other folks were generous with their time on another thread to point us towards a small success for us. After reading "The Path to Success for Block Storage" and "Some differences between RAIDZ and mirrors, and why we use mirrors for block storage", we think 4 striped vdevs of 2 drives each should be a fit. We think we're smarter at this point and trying to re architect it starting with this POOL.įor the first POOL we are going to use 8 4.3TB HGST drives. We learned a couple days ago of what not to do with our storage system the hard way so we turned to the boards. We currently have a VMware iSCSI POOL thats pretty critical to us.
