UK customers have been hit by Sequent's failure to hit delivery deadlines for its Numa multiprocessing server range.
The machines have been hit by delays caused, Sequent says, by rapid sales growth, which has created inventory problems.
The company admitted it had been a victim of its own success after sales soared beyond expectation, leaving the company struggling to meet delivery deadlines to UK and US users.
"Numa is now 90 per cent of our new server business and that has caused a bit of an inventory problem. We have not lost any customers because of this but some were very disappointed," said Steve Wanless, senior marketing manager.
Wanless said he expected the problems would be cleared up by Christmas. Delays were mainly due to problems getting hold of additional components required to produce the number of servers required to fulfil demand. He claimed the wait time for Numa servers had slipped from five weeks to seven, though some customers are believed to have experienced longer delays.
"The delay has been a real pain. We thought about re-evaluating our choice," said one affected IT manager.
Dave Chalmers, European head of technology, said part of the problem was that Sequent's past delivery record had been so good, with SMP servers generally being shipped within two to four weeks of orders. He said the rocketing sales had eclipsed sales of new SMP systems, which had effectively gone down to nothing as customers decided to buy Numa technology instead.
The majority of users were interested in the capability of Sequent's Numa server to run both NT and Unix operating systems. Many were also interested in consolidating applications running on a number of older systems onto the single Numa system.
Both Sequent and Data General, the two earliest vendors of Numa technology, have seen sales take off since their full Numa products were launched in the middle of the year. Other vendors, such as IBM, Sun and Silicon Graphics, have begun to focus more heavily on their own versions of Numa as the somewhat unexpected success of the technology has become apparent.
