If i have a LUN for 3TB im not able to give 3TB to my datastore. Is there anything I missed. I can see the LUN size in viclient as 3TB but i can use only 1TB at a time.
I know I can use extents but will that not break the VMDK into many partions and wont it be a extra overhead if I use thin prov on my vms
2. If I have a LUN of 3TB i can create 3 Datastores will that effect the performance of the LUN and RAID.
