I have a Cisco UCS running ESXi 5.0.0 with 7 8TB drives in hardware raid 6, making a 22.74TB drive, and I would like to create a VM with a 20TB drive running Linux.
Would it be better to upgrade to ESXi 5.5 (or later), or create the VM in ESXi 5.0 with a bunch of 2TB LUNs and software raid them within the VM?
(I don't manage the server, so I would need to get approval to get the upgrade done, so I just want to make sure I have the necessary information)
