Hitachi Data Systems (HDS) admits that its Trinium range of mainframes, which it promoted as the mainframe for the mega user, will be a fifth less powerful than expected.
HDS says problems with the memory subsystem means it has had to reclassify the performance of the Trinium, which ships at the end of this month. It was originally intended to have a performance of up to 3,200 million instructions per second (Mips). That has now been downgraded to 2,600 Mips.
"The Trinium is still the highest performing machine in the world," claimed Chris Douglas, general manager of systems for HDS Europe. HDS will post new performance figures when fixes are made to the system in November, although Douglas would not specify what they would be.
"This throws into question the performance HDS will actually be able to achieve with the box," said Rob Schafer, programme director for the Meta Group. "The big issue is not what HDS is shipping now, but what it will ship when the dust settles."
HDS has already shipped one Trinium in the UK, to Commercial General Union in York, which ordered a four processor model. HDS said it included an extra processor with the system to meet performance requirements.
