VNX5300 SP cabling question
Hello,
I know there are several conversations regarding this topic, but I have not been able to find a solution that answers my specific question.
We have (2) VNX 5300s in our organization. Array (A) is serving up LUNs to our VMware environment, and is replicating to another, Array (B), down the street.
We only have (1) fabric for our SAN. Currently we have one port from each SP plugged into a different switch at each site in the case of a switch failure.
My question is how should the SPs be zoned to each of my VMware HBAs (there are two HBAs per host).
Thanks in advance!
Rob

so single mode fiber connecting both switches ? Each HBA should be zoned to at least one port on SPA and SPB, ie:
hba1 - SPA0
hba1 - SPB1
hba2 - SPA1
hba2 - SPB0

Thanks Dynamox. Does it matter which combinations I use? Can I zone HBA1 to SPA0 and SPB0 or should it be alternating (HBA1 zoned to SPA0 and SPB1)? The only reason I am asking is that the way it was wired to our fiber swtiches was SPA0 and SPB1 were wired to the same switch and SPA1 and SPB0 were wired to a second switch. I don't know if that intrinsically matters or not (I would have wired A0 and B0 together and A1 and B1 if there were no other technical reason to do so).
Thanks again.

Rob,
actually the way it was wired is pretty standard, MirrorView (you may not need/use it right now) typically runs on ports SPA0 and SPB0. So if you were to use that functionality in the future you would want to have those ports on separate fabrics to give you high availability in case a switch in one fabric goes belly up.
