HP Integrity Mid-Range servers
rx7600 series
The 10U rx7620 is based on the SX1000 chipset which supports both PA-RISC and Itanium 2 CPU´s.
The 10U rx7640 is based on the SX2000 chipset which supports both PA-RISC and Itanium 2 CPU´s.
- Maximum of 2 cellboards

- 4 CPU sockets per cellboard
- 16 DIMM slots per cellboard
- Maximum of 4 SCSI-disks and 2 tape and/or CD/DVD-ROM internally (Half to each cellboard)
- 7 Hot-pluggable IO-slots per cellboard + 1 core IO slot per cellboard for SX1000
The rx7600 series are the smallest cell-based servers from HP, just like the bigger rx8600 and the Superdome these s
ervers can be partitioned, in this case either one big partition (two cells in one partition) or 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.![]()
- Maximum of four cellboards
- Four CPU sockets per cellboard
- 16 DIMM slots per cellboard
- Maximum of four SCSI-disks and two tape and/or CD/DVD-ROM internally (half to cellboard 0, half to cellboard 1)
- Eight Hot-pluggable IO-slots per cellboard and 1 core IO slot per cellboard for SX1000
The rx8600 series are the medium-sized cell-based servers from HP; just like the smaller rx7600 and the Superdome these servers can be partitioned, in this case either one big partitions (four cells in one partition) or divided into four partitions.
In contrast to the smaller rx7600 series servers, the rx8600 series servers have room for two more cellboards; these additional cellboards are only present to expand the CPU and memory capacity of the partition in which they belong.
The maximum number of partitions is four when used with an IO-expander unit (IOX); if there is no IOX present the system is limited to two partitions. This is because a partition requires IO-slots available, and the integrated IO-chassis in the rx8600 series is statically mapped half and half to cellboard 0 / 1).
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.
