==Mid-range servers== [[File:NodosHPIntegrityrx7640servers.jpg|thumb|HP Integrity rx7640 servers]] HP's mid-range and high-end (Superdome) servers are based on ''cell boards'', sometimes called ''cells'',<ref>[http://docs.hp.com/en/A5201-96044/ch01s04.html User Guide hp Integrity Superdome/hp 9000 Superdome, Ch. 1]</ref> which contain the chipset, [[Central processing unit|Processors]], [[Random access memory|memory]], and I/O [[Bus (computing)|bus]]. This design allows the servers to be divided into ''hardware partitions'', or groups of cell boards. Each partition is able to perform as if it were a separate server. ===rx7600 series=== The 10U rx7620 is based on the SX1000 chipset which supports both [[PA-RISC]] and Itanium 2 CPUs. The 10U rx7640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPUs. * Maximum of 2 cell boards * 4 CPU sockets per cell board * 16 DIMM slots per cell board * Maximum of 4 SCSI disks and 2 [[Magnetic tape|tape]] and/or CD/DVD-ROM internally (half to each cell board) * 7 hot-pluggable I/O slots per cell board plus 1 core I/O slot per cell board for SX1000 The rx7600 series are the smallest cell-based servers from HP. Just like the bigger rx8600 (see below) and the HP Superdome (see below), these servers can be [[Disk partitioning|partitioned]], either as one big partition (two cells in one partition) or as two independent cells. ===rx8600 series=== The 17U rx8620 is based on the SX1000 chipset which supports both PA-RISC and Itanium 2 CPUs. The 17U rx8640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPUs. * The rx8620 was announced in 2003, along with the rx4640 and rx7620<ref>{{Cite web|date=2003-11-03|title=HP Unveils Itanium Servers|url=https://www.pcworld.com/article/113249/article.html|access-date=2020-12-10|website=PCWorld|language=en}}{{Dead link|date=July 2024 |bot=InternetArchiveBot |fix-attempted=yes }}</ref> * Maximum of four cell boards * Four CPU sockets per cell board * 16 DIMM slots per cell board * Maximum of four SCSI disks and two tape and/or CD/DVD-ROM internally (half to cell board 0, half to cell board 1) * Eight hot-pluggable I/O-slots per cell board and 1 core I/O slot per cell board for SX1000 Just like the smaller rx7600 (see above) and the HP Superdome (see below), the rx8600 can be partitioned using any combination of the four available cell boards (minimum of one, maximum of four separated partitions). The maximum number of partitions is four when used with an I/O-expander unit. Because each partition requires an available I/O slot, and the rx8600 series' integrated I/O-chassis statically maps its two I/O slots to cell board 0 and 1, an rx8600 series system is limited to two partitions unless an IOX is installed. Cells can be freely moved from a rx7600 series to a rx8600 series as long as the chipset is the same on the cells, and the [[firmware]] is compatible.
