Rex, Perhaps they did not explain themselves correctly.
Only Hitachi writes the microcode for the RAID500 storage controller. Sometimes they add things especially for HP, sometimes they add things just for us, and sometimes they add things for everybody. This is true from the 7700E/XP256 through to the current USP/XP1024. The difference is simply the Vendor ID and the names of the software displayed in Storage Navigator or the Service Processor. The difference is really in the software and API. To over-simplify, software will simply verify the vendor id. If one of our software exclusives finds a HPQ vendor id then it will apply any required limitations - including not recognising it at all. The same is true for HP exclusive software when it finds a HDS box. I heard similar misquotes about microcode development, but I think that it was cleared up many years ago. HP is a great partner of Hitachi, and I for one think that XP storage is fantastic :) Ron > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On > Behalf Of Pommier, Rex R. > Sent: Tuesday, 18 July 2006 10:15 PM > To: [email protected] > Subject: Re: MIDAW on non-IBM Devices > > Ron, > > I have an XP512 box and HP has told me that they have made a bunch of > microcode changes so the XP boxes (at least the XP512) aren't the same > as the HDS any more.
