IBM last month raised the price umbrella in the mainframe world, and so Amdahl Corp has gratefully followed suit, raising the base prices of all mainframes and of the 6100 Storage Processor by 5%, although, also in reaction to the IBM move, it has had to cut main and expanded processor storage by varying amounts. Prices of some features were also adjusted, Amdahl said, adding that the net effect of the changes mean a reduction of as much as 4.4% in total system costs for the largest configurations with lots of memory, to a rise of 5% for systems with base memory configurations. The 6100 Storage Processor will rise between 2% and 8% depending on configuration, and the company has also increased the price on its 37XX-compatible front-end communications processors by 10%, coincident with the availability of new and advanced features on the box; the increases take effect immediately.
