NEWS IBM has increased the processing speed of its latest range of mainframe computers. The company says the upgrade will nearly double the computing power of its flagship z900 from 2,000 to 3,850 secure transactions per second. At the same time, IBM launched an enhancement for the zOS, which allows the mainframe to be partitioned while running Linux. Partitioning allows mainframe computing power to be distributed to a number of server functions. The company has seen a resurgence in the interest in mainframe integrations in recent years. IBM admitted it has seen double digit growth in its eServer z900 product over the last four quarters, due in part to users consolidating server power. The mainframe market suffered shrinkage in the 1990s as companies invested heavily in PCs. Analysts believe the mainframe market now accounts for 40 per cent of IBM's operating profit.
