We have a VM ESXi 5.x host using local storage (DAS).
It has 2 relatively large Logical Drives in RAID10 (10 HDD x1TB each). So, 2 LUNs of 5TB each.
We are considering creating just two datastores, one for each Logical Drive, as we believe that there is no VMFS5 added contention when dealing with local storage (there would be contention in a NAS accessed by multiple hosts).
Is there any advantage on creating more/smaller datastores?.
