Mainframe shops gush over big iron

But investment is not resurgence

High performance access to file storage

Analysis Mainframe maker IBM and its few remaining peers that sell their own mainframes are probably cheered by two recent surveys of mainframe shops, one that came out of market researcher IDC and the other out of mainframe software maker CA. But maybe not.

IDC polled some 300 IBM mainframe shops and kicked out a study with the ponderous name Directions in the Multi-Platform Data Center 2009-2013: Today's Workloads and Future Outlook. This is IDC document 219797 and the 64-page report packs a mainframe-class price, at $20,000.

Given the value that IDC places on this report, the tidbits that it leaks out to the IT trade press are pretty thin. But the box counter was willing to reveal that nearly half of the 300 respondents in the survey said they would increase their annual spending on mainframe hardware and software. And in another comment, IDC said that mainframe shops "can plan another wave of investments in the System z platform over the next 2 to 5 years, given the system's high availability, reliability, and security for mission-critical applications."

This is the same old mantra that IBM and other interested mainframe parties - such as IT consultancies and third party software suppliers that peddle products for mainframes - have been chanting for decades. They don't get tired of saying it or hearing it.

What I want to know is if nearly half of the respondents said they were going to increase mainframe budgets, what were the more than half of mainframe shops planning? Do they expect their budgets to be flat? Are they planning cuts? And if some shops are planning cuts - which seems very likely given the intense pressure on all platforms to offer better bang for the buck - will these cuts be so deep that they wash out any planned increases by other shops? The IDC report, or more precisely the summary that the public can see, raises more questions than it answers.

What can be said is that by corralling some mainframe engines, slashing their prices, and letting them run Linux instances or speed up Java or DB2 workloads, IBM has been able to keep the installed base of mainframe processing power, as measured in MIPS, growing - even as it has its ups and downs each quarter. And the downs have been especially sharp since the economic meltdown kicked in a year ago.

Feeder boxes

The advent of lower-priced System z Business Class machines, a sort of midrange mainframe akin to the ones that acted like feeder boxes into bigger iron in days gone by, has also helped keep mainframe shops from dumping their big iron for Unix, Windows, or Linux iron by reducing the hardware and software costs of mainframes.

Mainframe deals take a long time to get done, and to stop. IBM's System z sales were up 25 per cent, while MIPS shipped rose an impressive 49 per cent in the third quarter of 2008, before the economy started to collapse in the United States.

In the fourth quarter, mainframe sales dropped six per cent, while MIPS shipments and MIPS grew by only 12 per cent. By the first quarter of 2009, System z sales fell 19 per cent.

But because IBM was peddling the System z BC and aggressively pushing its Integrated Facility for Linux and zIIP and zAAP accelerator engines (which cost a fraction of a mainframe engine set up to run the z/OS operating system), the company was still able to crank up the MIPS by 18 per cent. (I get the impression that IBM's System z managers are getting bonuses based on MIPS and profits, not revenues.) In the second quarter of this year, against a very tough compare, mainframe hardware sales declined by 39 per cent and MIPS shipped fell 20 per cent.

It came as no surprise, then, in August when IBM launched System z solution edition bundles, which are designed to only have a 20 per cent premium for a bunch of different workloads compared to Hewlett-Packard Integrity servers running HP-UX, and slashed prices on specialty mainframe engines by half.

We're about to see how elastic demand is for mainframe processing capacity. So far, IBM has done a pretty fair job of keeping hardware sales relatively flat on an annual basis. My own estimates, based on the thin data that IBM gives out each quarter, peg mainframe hardware sales at $3.61bn in 2006, $3.18bn in 2007, and $3.61bn again in 2008. The first half of 2009 has been particularly awful, with sales down 28.4 per cent to $1.18bn, by my estimates. IBM has to rake in $2.43bn in mainframe revenues in the second half of 2009 to break even with 2008, and $2bn to match the not-so-great 2007 year.
