I am trying to understand how VMWare connects to a SAN and Two NAS storage devices and would like some help on the configuration of connections to those devices. We had a consultant come in and connect a new EMC Unity 300 with 10K drives to a VMWare cluster of three hosts. We have our Exchange and SQL servers virtualized but since we have done this our SQL server is dog slow. I have been looking on Vsphere at the VM network configurations and they don't seem right. I have attached screen shots of the configurations and hope you can lead me down the right path of understanding.
I have been reading on the net that the VMKernal is an iSCSI connection to the storage devices but is there supposed to be multiple connections? Also on two of the hosts the VMKernal has the same IP, is that right? Now when It comes to the EMC unit I probably need help with that as well but lets first start with the VMKernal question and the Management network connection. I assume those are supposed to be tow separate IP's and connections.
