The HP Superdome is a high-end server computer developed and produced by Hewlett-Packard. The latest version of product, "Superdome 2" was introduced in 2010. Superdome 2 scales from 2 to 32 sockets (up to 128 cores) and 4 TB of memory. When introduced in 2000, the Superdome used PA-RISC processors. Since 2002, there has been another version of the machine based on Itanium 2 processors, marketed in parallel as the HP Integrity Superdome. The classic PA-RISC Superdome was subsequently rebranded to HP 9000 Superdome. The predecessor of the Superdome was the V-Class, the HP's first cell-based architecture.
The new HP Integrity Superdome 2 utilizes the Intel Itanium 93xx-series microprocessor, otherwise known as "Tukwila" and is totally redesigned with parts from the HP BladeSystem C7000 enclosure. Since 2012 Intel Itanium 93xx microprocessor Poulson are available too.
Superdome usually runs the HP-UX operating system, although the Itanium 2 version is also compatible with many other systems, for example with Microsoft Windows Server 2008 R2, SUSE Linux Enterprise Server, Red Hat Enterprise Linux, Debian Squeeze, and OpenVMS V8.2-1.
