EqualLogic firmware 7.0.0 now gives us the option to create volumes with 4k sectors rather than the legacy 512e sector size. I thought it would be interesting to create two EqualLogic volumes, one 4k, one 512e. Then create to VMs and IO meter to see if there are any performance gains.
The two volumes could be seen by the ESXi 5.5 host but
I am surprised that considering 4096 byte sectors have been around since 2010 that VMware has no compatibility for this disk format.
ESXi + 4K disks = :(
