HPE Superdome

The HPE Superdome is a high-end server computer designed and manufactured by Hewlett Packard Enterprise (formerly Hewlett-Packard).

The product's most recent version, "Superdome 2," was released in 2010 supporting 2 to 32 sockets (up to 128 cores) and 4 TB of memory.

[1] In 2016, Hewlett Packard Enterprise released the Superdome X, which is based on Intel Xeon processors, supporting 16 CPU sockets and 24 TB of RAM memory.

Superdome usually runs the HP-UX operating system, although the Itanium 2 version is also compatible with other systems, for example with Microsoft Windows Server 2008 R2,[2] SUSE Linux Enterprise Server 11 SP4,[3] Red Hat Enterprise Linux,[4] Debian Wheezy[5] (Long Term Support for it has ended),[6] and OpenVMS V8.2-1.

[7][8] There are 4 different generations of the Superdome: A building block is a cell, a card holding 4 processors and memory.

In the maximum machine configuration, four second-level crossbars interconnect with each other, supporting in total 64 processor sockets.

Superdome supports nPars (hard partitions), that are granular on the level of a whole cell (and its I/O card cage).
