Under the deal, customers with Power4-based pSeries 670 and 690 servers can trade in these boxes and their associated racks and get a trade-in after they purchase a new p5 590 or 595 server. That is a pretty serious upgrade in performance. To sweeten the deal, IBM is tossing in some processor activations on these machines, which are pretty pricey as well.

The trade-in credits span from $32,400 to $216,000, with the amount growing as customers do a box swap for progressively bigger boxes. This trade-in rebate deal runs until December 23, and customers have to install the gear before January 23, 2006. Customers get the rebate back when IBM gets the older pSeries iron in its hands.
