Just to add
In VMFS 3 you can have a 64TB datastore, but this will be made out of extends not bigger than 2TB.
Which means you'll use 32 2TB LUNs for 1 datastore. This is not recomended though. Loose 1 LUN loose whole datastore.
Where with VMFS 5 you can creat one 64TB LUN (if storage supports it) and make it a datastore.
Keeping the best practice ratio of 1:1 = 1LUN per 1 Datastore
For more information please see VMFS 3 vs VMFS 5

Hi
What is the maximum LUN size in vmfs3 and vmfs5 ?
VMFS 3 = vsphere 4
Maximum Lun size = 2 TB
Maximum vmdk = 2 TB
Maximum RDM = 2 TB
VMFS 5 = vSphere 5
Maximum LUN size = 64TB
Maximum vmdk = 2TB
Maximum RDM virtual mode = 2TB
Maximum RDM Physical mode = 64TB
