Hardware Today: IBM Server Snapshot
IBM would seem to have it made. The server vendor is No. 1 worldwide in revenue according to IDC, with six distinct product lines and a steady stream of new releases. According to the research firm, IBM is tops in Unix server revenue (a 31 percent share) and blade servers (a 40.9 percent share), and No. 2 in Linux servers (a 20.3 percent share). Factor in its near monopoly in mainframes and consistent sales in Intel-based servers, and it's difficult to see any vendor posing a threat to IBM any time soon.

"IBM maintains the No. 1 spot in the worldwide server systems market with 31.9 percent market share in factory revenue, growing its revenue by 4.1 percent when compared to the second quarter of 2004," says IDC's Jean Bozman.
IBM has been comparatively quiet in recent months as far as its iSeries (midrange servers), pSeries (Unix servers), and OpenPower (Linux) lines. The big noise has come from the zSeries (mainframe) and xSeries (Intel- and AMD-based servers) lines.
Before we take a close look at changes that have occurred in the xSeries and zSeries lines, we offer a panoramic view of all six IBM server lines with the following chart.

1 New i5 systems are part of the iSeries line despite the slightly different nomenclature.
2 New p5 systems are part of the pSeries line despite the slightly different nomenclature. The pSeries line also includes the JS20, 2-way PowerPC 970 BladeCenter system.
3 Commercial Blue Gene runs PowerPC 970 processors and is 5.7 teraflops. Contact IBM for pricing.
4 The 445 replaces the 440.
5 The zSeries line also includes the S/390 G5/G6 and S/390 Multiprise, which are no longer sold but are still supported.
6 Based on IBM's posted prices.
7 The packaged configuration includes 70 GB of disk, 1 GB of memory, and a DVD and tape drive.
