I am trying to see if there is anyone with Dell Compellent (SCOS v7x) that is successfully seeing Auto-Reclaim work against a VMFS6 volume.
The HCL says that Dell Compellent with v7.x SCOS code will support auto-reclamation of VMFS6 volumes.
I am not seeing that happen though. Even after about 5 days of monitoring and testing by creating or cloning VMs on VMFS6 and then deleting them. I see no VAAI commands being issued in estop after days. I cannot really find anything in any logs that states its not working.
A theory right now is that Dell Compellent default 2MB data page size is being used and Unmap granularity, in which case it will not work at all.
However, Dell Compellent with v7.x SCOS is supported on the VMware HCL, which is the strange part to me. No where does it say anything about the page size.
