I have a partial answer, to start.... To my knowledge zHPF is no longer a separately chargeable extra, not for several years with IBM gear. My recollection is that zHPF became part of the base FICON attachment feature starting with the 2016 introduction of the IBM DS8880 series equipment. If a SAN switch vendor wants/wanted to charge something I couldn't say, but SAN switches are technically optional. Also to my knowledge there was never anything chargeable on the IBM Z server side for zHPF. The base z/OS operating system included support as a standard feature (maybe with PTFs depending on the release level), and the standard FICON Express features included the necessary hardware support all the way back to FICON Express2. Server support goes back to the IBM z10 models. Maybe a firmware/microcode update was required (likely for z10), but all that should be ancient history by now. Are you thinking of IBM zHyperLink(s) perhaps? zHyperLink is separately chargeable in the sense that it uses dedicated zHyperLink features with their own ports (on both ends) and separate/additional cables. You mentioned "files," so I assume you shouldn't have anything in particular to do to exploit zHPF. If the volume (EAV in this case) is zHPF enabled then DFSMS Basic Access Methods (BSAM, QSAM, BPAM) should "automagically" work. - - - - - - - - - - Timothy Sipples I.T.
