So when I was dabbling with the linux VSA, I noticed that the ZFS repository is present. You can't (apparently) actually install zfs, because it is a alternative kernel (4.10?). It would be a plus, IMO, if you supported ZFS. Aside from the checksumming protection, I found (when I had my dozen or so home lab VMs on a ZFS pool with transparent lz4 compression) that I was getting about 50% compression. This translates directly into fewer IOPS required.

Will do, thanks! I'm curious whether you intend to go with block LUN (e.g. zvol) or file based LUN (e.g. a file on a dataset, which you then share out via iSCSI). I ask because zvol I/O on ZFS on Linux has been quite underperforming, relative to file based I/O.
