I am used to the Concatenated Raid Groups on the USP and I think it was a turning point in performance. I noticed that you can also have Concatenated Raid Groups on the USP V and this raises questions. When I read the user and reference guide for the USP V, it discusses LDEV striping across Array Groups. I can't see any way of striping LDEV's using Storage Navigator, so is this just the same as concat RGs that has to be setup by the HDS people?
Also, is there any issues with concat RG's and HDP?
