We are currently running a single z/VM 5.3 (701) system on Hitachi 7700E disk, set up as 3390-3, connected to a z9BC via ESCON. This has worked well, but the limited disk storage has kept us from growing past the 15 RH Linux guests. We are in the process of installing a new Hitachi USP V that will give us the storage capability to use some M9 and M27 for some of the new servers that are planned. With those volume sizes I am anticipating that we will need to utilize PAV for some applications. We don't have any prior experience or knowledge other than what the manuals tell us. Everything I have found on the subject so far has been pretty generic. We were looking at Hyper-PAV or possibly dynamic. Will dynamic PAV work for z/VM 5.3? Can anyone share any experiences or their particular application? (Volumes? Minidisks? Particular applications i.e. DB2, etc?) Appreciate any and all input.
Dave
