ReFS VS Dell Compellent

We have been using ReFS with a lot of trial and errors over the last 6 months, but we lately found out that the space savings in the OS of a Backup Repository were not showing on the Thin-Provisioning Dell Compellent SC-Series SANs. Turns out that Dell Compellent does not support TRIM/Unmap with ReFS LUNs. While we do have other advantages with ReFS, it appears that the space savings on thin Dell SC SANs is not something to factor in.
