Power Systems is the name of IBM's converging Power Architecture based server lines, System i and System p, running either PowerVM, IBM i, AIX or Linux operating systems. Power Systems was announced April 2, 2008, at the same time as they renamed their i5/OS "IBM i".

[edit] History

IBM had two discrete Power Architecture based hardware lines since the early 1990's. High end PowerPC-AS based servers in the AS/400 (later iSeries and System i) family running OS/400 (later i5/OS) and the POWER and PowerPC based workstation and mid range servers in RS/6000 (later pSeries and System p) running AIX and Linux. They merged to use essentially the same hardware plattform in 2001/2002 with the introduction of the POWER4 processor. After that hardware variants differed little between the "p" and the "i" hardware, the major differences was in the software and services offerings. With the introduction of the POWER5 processor in 2004, even the product numbering was synchronized. The System i5 570 was virtually identical to the System p5 570. In April 2008 IBM officially merged the two lines of servers and workstations under the same name, Power Systems, with identical hardware and a choice of operating systems, software and service contracts.

  • Power 520 Express
  • Power 550 Express
  • Blade Center JS12 Express
  • Power 570
  • Power 575
  • Power 595
