"IBM Corp last week announced that it has delivered the AIX 5L Release 5.2 version of its Unix operating system for its pSeries RISC-Unix servers... While most Linux customers don't care much about what IBM does or does not do in the pSeries line, my sources at the company say that IBM might be readying a set of Linux-only Power4-based 'Regatta' servers to take on the Unix installed base--including Big Blue's own AIX base. This would be a very interesting development, indeed.

"IBM already supports Linux within logical partitions on the four-way pSeries 630 'Regatta-LE', the 16-way pSeries 670 "Regatta-M" and 32-way pSeries 'Regatta-H' servers. With AIX 5L 5.2, which starts shipping next week, the pSeries Regatta line of machines gets support for dynamic logical partitions, which can be configured with AIX 5.1, AIX 5.2, or Linux 2.4. These dynamic logical partitions can be based on a single processor, as little as 256MB of main memory, and a single I/O adapter card that talks to disk drives.

"This week, the pSeries line has also been improved to include dynamic processor sparing in 16-way pSeries 670 and 32-way pSeries 690 Regatta servers. This capability allows customers who acquire Capacity Upgrade on Demand (CUoD) configurations (which have extra processors in the box to cover peak loads) to permanently and transparently activate CUoD processors, in lieu of a failing or failed processor, in these Regatta machines. Your run-of-the-mill Linux servers don't have such partitioning or sparing capabilities, and IBM is well aware of this..."
