This is a new setup of ESXi 4.0 running VMs off of a Cybernetics miSAN D iSCSI SAN.
Doing a high data read test on a VM, it took 8 minutes vs 1.5 minutes on the the same VM located on a slower VMWare Server 1.0 Host with the VMs located on local disk. I'm watching my read speeds from the SAN, and it's getting just over 3MB/s max read, and Disk Usage on the VM matches at just over 3MB/s....horribly slow.
The server and SAN are both connected to the same 1GB Switch. I have followed this guide
to get multipathing setup properly, but I'm still not getting good performance with my VMs. I know the SAN and the network should be able to handle over 100MB/s, but I'm just not getting it. I have two GB NICs on the SAN multipathed to two GB NICs on the ESXi Host. One NIC per VMkernel. Is there something else I can check or do to improve my speed? Thanks in advance for any tips.
