IBM has announced that it will withdraw from marketing a bunch of Power Systems-related products starting on January 4. I counted 91 different feature numbers, so if you have an older Power-based server, it might do you well to take a quick scan and see if you need anything.
IT Jungle listed what it considered to be some of the more important items:
The processor cables that are used to lash multiple Power 570 boxes together into a single SMP server are going, so is the dual-port GX host channel adapters and conversion cables for the original Remote I/O (RIO, a variant of Fibre Channel) to the RIO-2 (a faster Fibre Channel) external drawers. A whole slew of SCSI cables are biting the dust, and as are dual-line power cords used with earlier Power 570 and Power 595 boxes, and so is the twinaxial workstation controller used in the current Power Systems lineup. (That could be a biggie for a lot of i shops.)
The article also lists of bunch of other processor and memory cards, and power supplies.
