IBM has announced two promotions for these servers. The first gives customers who buy upgrades for their pSeries 690 servers (that is the 32-way Regatta-H box) from the 1.3GHz Power4 or 1.7GHz Power4+ processors to the faster 1.9GHz Power4+ Turbo processors a 65% discount. The deal applies specifically to feature 5241, an eight-core Power4+ complex that has a list price of $800,000 and feature 7431, which is an eight-core module with only four cores activated that costs $228,000. This promotion expires June 22.

In addition to the discounts on those top-end Power4+ chips for the pSeries 690, IBM is also offering a 65% discount on activations of Power4, Power4+, and Power4+ Turbo processors in existing pSeries 670 (16-way) and pSeries 690 machines. Customers have to activate cores in increments of four, and they also have to activate 8GB or 16GB of main memory on those systems at the same time. This is a lot of dough, but IBM is giving what is probably the most generous discounts in its history on these features. This deal expires on June 24.
