HPs Superdome servers are their flagship PA-RISC and Itanium2 based High-End machines.

Currently offered in either PA-RISC or Itanium2 processor configurations, the Superdome line represents enterprise class computing on the largest scale. These machines start at 16-Way capability and scale up to 128-Way with up to two TB of memory. Just like the Mid-Range HP9000 line of servers, HP will be phasing out PA-RISC based servers which will mean the end of HP9000 Superdome servers as of 2009.

At the heart of Superdome servers is the sx1000 cell chipset.
