I have a scenario where by they want to have a Win2k3 virtual server to have access to about a 2tb RDM lun. I am not a fan of RDM. Other choices would be vdmk drive or maybe cifs.
Environment is clustered esxi 4.1 hosts connected with fiber and 10Gbe for NFS and fas6280
I want it to be a flexible solution where by I dont want him to negat eany performance or expandability later on.
thoughts ideas and recommendations?

Guess you are aware of 2TB datastore limit for iSCSI in VMware: http://kb.vmware.com/selfservice/microsites/search.do?language=en_US&cmd=displayKC&externalId=1003565.
One option is you can have extents and increase the datastore size (not sure about the performance in this case)
or the other option is to create a NFS datastore of more than 2TB size and have your 2TB vmdk drive on that.

Yes sir.. I am aware.. thanks..
Also what about having a large vmdk like that.. ? Is that efficient? To me i think having that large vmdk sounds the most convient and easiest to deploy but i was just wondering about the managbility of it.
thanks for your response!

That question should be for VMware . However seems like VMware claims to have no issues with large vmdk’s as per the following link http://communities.vmware.com/message/1212587#1212587.
Hope this is useful.
