So, I'm new to this. But I've read the docs 
I have two esxi hosts, physical, that I've pulled into my vCenter. I'm trying to cluster them and configure them with storage to support an evaluation vCloud Director. I understand that this means that I need shared storage to support vMotion and other power features. I'm trying to confirm if the storage devices reported for the two hosts are adequate for this. I believe they are not; it appears to me that I have two separate fiber channel luns that are each attached to one of the hosts. But as I understand it, these luns need to both be attached to both of my hosts in order to support the shared storage scenario and all the vMotion and co. that goes with it.
The only thing I'm unsure about it how to interpet the device ids reported.
Here's one of the luns as reported on one of the hosts:
DGC Fibre Channel Disk (naa.60060160b7fc3000eec4739918b1e211),disk,4.00 TB,Attached,Supported,Non-SSD,Fibre Channel
The other host as an identical 4TB lun attaches as well, but the id ( naa.xxxxx ) is not the same. So, my question is, is this ID expected to be the same on everyhost that the lun is attached too. The docs say that the id is "globally unique across hosts", but that verbiage, for whatever reason, doesn't quite clarify things to me -- I mean, it could be unique across hosts, but that's not quite the same thing as it being singluarly bound to a device across all hosts.
