First of all, it's not a sales pitch. I don't do sales pitches very well. Second, it's also no longer possible to "write directly" to disk drives. *All* mainframe-attached storage -- flash/SSD, disk, and now tape -- is highly virtualized, with intelligent controllers equipped with caches. Why is this progress a problem? And it's a very long arc of progress, not at all sudden. As I've carefully and accurately documented, there was nearly 19 years of product overlap as IBM tape made the transition to virtualized-physical. Finally, "ask your friendly IBM representative" about IBM TS1155/TS4500 attachment to your IBM TS7700. I have no inside information on that, but I do pay some attention to IBM's past practices. What I see is that, for several generations of tape drives stretching back many years, IBM has waited some period of time before certifying z/OS use of that new tape drive/tape media/density. I suspect that's because IBM is just being that extra bit careful with your most precious data (such as most of the world's most important financial records) and its long-term retention needs, but ask. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM Z & LinuxONE, Multi-Geography E-Mail: [email protected] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
