The HP Integrity server family, based on the Intel® Itanium® processor, supports Linux on a full range of server models. This range includes entry-level servers, such as the 2-processor rx1620; mid-range servers, such as the rx7640 and rx8640; and the high-end 128-processor Superdome.
Some servers, such as the HP Superdome, rx8640, and rx7640 servers, are based on the HP Super-Scalable Processor chipset (sx1000 or sx2000). They are composed of basic building blocks known as cells. These cell-based servers can be set up as a single system or divided into multiple partitions, where each partition is assigned memory, processors, and I/O resources for its exclusive use. Each partition can execute its own OS image.
