Need to attach my 10 TB partition on PS400E to ESXi5 server
I have an Equallogic PS4000e SAN. When I had a physical server 2008 I was able to attach a 6 TB volume to the server and saw all 6 TB using the iscsi intitiator in Server 2008. I now have a virtual server 2008 and I need to attach a 10 TB volume and see it as the whole thing to the virtual server. I can add 2 Tb using the VMFS 5 but not larger than that. I have the network config setup in VMware for ISCSI.
Do I need to use RDM for this for larger than 2TB?
thanks

macpiano,
Here's VMware's KB covering it kb.vmware.com/.../search.do
Of note:
What are the limitations for VMFS-5?
VMFS-5 still limits the number of extents to 32 and the total datastore size to 64TB, but the individual extents are no longer limited to 2TB each. For example, a datastore can be created with a LUN size of 64TB, or a datastore can be created with up to 32 extents up to maximum size of 64TB.
Only pass-through RDMs (Raw Device Mapping) can be created with a size >2TB. Non-pass-through RDMs and virtual disk files are still limited to 512B ~ 2TB.
Passthrough RDMs are supported up to ~60TB in size.
Both upgraded and newly-created VMFS-5 volumes supported the larger Passthrough RDM size.
Non-passthrough RDMs are still limited to 2TB minus 512B.
Also, here's another good coverage of the topic: communities.vmware.com/.../1717827
