The System p, formerly known as RS/6000
RS/6000
RISC System/6000, or RS/6000 for short, is a family of RISC and UNIX based servers, workstations and supercomputers made by IBM in the 1990s. The RS/6000 family replaced the IBM RT computer platform in February 1990 and was the first computer line to see the use of IBM's POWER and PowerPC based...

-based server and workstation product line.

In April 2008, IBM announced a rebranding of the System p and its unification with the System i platform. The resulting product line is called IBM Power Systems
IBM Power Systems
Power Systems is the name of IBM's Power Architecture-based server line.Before the Power Systems line was announced on April 2, 2008, IBM had two distinct Power-based lines: the System i running IBM i - and the System p series running AIX or Linux.- History :IBM had two discrete Power Architecture...

History


It was originally a line of workstations and servers called RS/6000. The server line was then renamed to the eServer pSeries in 2000 as part of its e-Server branding initiative.
With the advent of the POWER5 processor in 2004 the family was rebranded the
e
Server p5
.
With the global move of the server and storage brands to the System brand with the Systems Agenda, the family was renamed yet again to System p5 in 2005.
The System p5 now encompasses the IBM OpenPower

With the introduction of POWER6 processor models the new models are now being released under the System p brand, dropping the p5 designation.
