HP P2000G3 MSA iSCSI redundancy for VMWare ESXi
Posted on 2011-02-16
I'm looking to set up a 1Gb iSCSI P2000G3 hard disc enclosure, and want a redundant config for VMWare ESXi. I already have two switches, and there'll be two controllers in the storage. I understand that each controller should be connected to both switches - the wiring is very well explained on HP and DotHill's websites.
What I don't understand is the IP configuration. I need to configure 4 ports, and they all ned different IP addresses. Do they need to be on different subnets? HP say yes, and then give a clear example of different addresses on the same subnet (255.0.0.0 netmask!).
My current iSCSI storage is on 172.17.1.0/24 - can I establish the new storage on that one class-c subnet? Should I put both port-0s on that subnet and both port-1s on a different subnet? Should the subnets be routable? (My router is only 100Mb...) Should I put subnet A on one switch and subnet B on the other?
I know that's a lot of questions - a link to a decent HowTo would be fantastic! :)
