FAST VP is not available on the AFA and the tiering calculation behind FAST VP is not running. I think (I have not gotten a definitive answer) the reason is concern about excessive wear on the EFD caused by the FAST VP relocations. This "may" change in the future.  glen
Hi,  there is no FAST VP in a All Flahs array, which seems normal between tiers (as there is only one). But what about the internal FAST VP that exists even in a homogenous pool/tier in VNX2 ? Is it stil present in Unity ? So do we have to activate FAST VP even on a All Flash Unity ?  Thanks. 
Unity All Flash : no FAST VP, even for the internal rebalance ?
