IBM enjoys rebranding products to keep them relevant and current to the user population.
For anyone who is yet to ‘catch up’ the following is a quick summary of some products that share ‘dual personalities’.
System 390 = zSeries = System z (Mainframe)
AS/400 = iSeries = System i (Midrange OS/400)
RS/6000 = pSeries = System p (Midrange Unix)
FastT600 = DS4300 (Fibre Disk Array)
FastT700 = DS4400 (Fibre Disk Array)
FastT900 = DS4500 (Fibre Disk Array)
UPDATE: IBM have since replaced System i and System p with the new IBM Power Systems.
