Direct SAN Restore Thick vs UNMAP Thin

Post by regnak2012 » May 26, 2017 3:06 pm

Quick design decision:
I'm designing an iSCSI based VMware solution with a physical Veeam proxy server. I hope to do Direct SAN Backups (3PAR). I've got 2 x 10Gb iSCSI ports on the Proxy and 2 x 1Gb for management. So if I go Thick on the VM I'm good and can get Direct SAN Backup AND Restores.
I'd like to use the new vSphere 6.5 UNMAP feature which requires THIN VMs! This is required for in guest UNMAP. Dooh!

Am I missing anything or are these two features mutually exclusive?!

DirectSAN Backup is pretty fast, but DirectSAN Restore (to thick disks) is pretty slow compared with the other restore methods by design of VMware (coordination with vCenter/Host in the background). I would suggest to add a HotAdd proxy just for restore.
