I think you have a basic misunderstanding here. The models which come with dormant processors (825, 870, and 890) will do so regardless of whether they are ordered with the Standard or Enterprise packages. > It would be quite nifty to be able to purchase a machine for > high-availability with a product such as *noMAX (or MIMIX, Vision or > Data Mirror).

Processors and interactive performance are really two different things and are not directly related. You either buy the Enterprise package or you don't. You either activate the processors (temporary or permanent) or you don't. You do have a good point that you could undersize a DR machine with only enough processor power to replicate. Then you could temporarily activate additional processors for the duration of your disaster. But you would not be able to just switch 5250 on and off under IBM's current offering. > Is there a place for such an animal?

IBM has, in the past, specifically addressed this issue with discounts or rebates on DR machines of a minimum configuration purchased with an approved high-availability product. I've forgotten most of the details but I seem to recall that it involved allowing your system to be monitored (like PM/400) so that it doesn't exceed certain performance limits except for a few days a year. Now that they've reconfigured the way they package the systems, I would look for them to come up with new incentives for customers to implement high-availability. As you say, it is to their advantage and to purchase an entire enterprise suite for use during only disasters may be financially prohibitive. The relevant announcements for these previous offers are 301-106 (July 2001), 302-015 (February 2002), and 302-063 (April 2002). Because they've done it in the past, I would expect them to do it again. For anyone looking to implement a new high-availability installation, it might be worth waiting to see what they do, or try to force their hand. > What do the genii think? > > Cheers. > > Jan. > > _______________________________________________ > This is the Midrange Systems Technical Discussion (MIDRANGE-L) mailing > list > To post a message email: MIDRANGE-L@midrange.com > To subscribe, unsubscribe, or change list options, > visit: http://lists.midrange.com/mailman/listinfo.cgi/midrange-l > or email: MIDRANGE-L-request@midrange.com > Before posting, please take a moment to review the archives > at http://archive.midrange.com/midrange-l.
