We have DSS-G (Lenovo equivalent) in the same cluster as other SAN/IB storage (IBM, DDN). But we don't have them in the same file-system.
In theory as a different pool it should work, note though you can't have GNR based vdisks (ESS/DSS-G) in the same storage pool. And if you want to move to new block size or v5 variable sunblocks then you are going to have to have a new filesystem and copy data. So it depends what your endgame is really. We just did such a process and one of my colleagues is going to talk about it at the London user group in May.

Can the ESS nodes be added to existing scale cluster without changing existing cluster name? Or do we need to create a new scale cluster with ESS and import existing filesystems into the new ESS cluster?
