The HP Integrity rx8640 is a cell-based symmetric multiprocessing server built on the sx2000 chip set. It takes up to sixteen dual-core Itanium processors (the 90X0 and 91X0N series, 32 cores in all) spread over one to four cell boards, with up to four processors on each cell. The AB297A base is the starting point, and the FAST bundles AB443A (4 processors, 8 cores, one cell board and three power supplies), AB444A (8 processors, two cells, four supplies) and AB446A (16 processors, four cells, six supplies) arrive semi-configured. Cell slot 0 or 1 is filled first, the suggested cell order is 0, 1, 2, 3, and processors go onto each cell in the sequence 0, 2, 1, 3, with one active core required per processor on a cell and the second core held as Instant Capacity. Within a cell every processor must match, and 1.4 and 1.6 GHz parts, 12, 18 and 24 MB cache sizes, and Montecito and Montvale generations cannot be combined on one cell or in one partition. The rx8640 shares its cell board with the eight-processor rx7640.
Memory is custom HP DDR II at 267/533 MHz with full ECC, in 2 GB, 4 GB and 8 GB DIMMs fitted two at a time as AB454A (4 GB), AB455A (8 GB) and AB456A (16 GB) modules, or as the AH411A to AH414A bundles of 128 GB and 256 GB. Each cell board carries 16 DIMM slots and 17 GB/s of peak memory bandwidth, and the whole system reaches 512 GB. Pairs go in slot order (0A, 0B) through (7A, 7B), the largest DIMMs first, and a multiple of eight DIMMs per cell fills both memory buses; a cell with only one bus populated delivers half the bandwidth. Spread memory evenly over the cells. Memory, cell boards and core I/O from the rp8400, rp8420 and rx8620 do not carry forward, while rx8620 1.6 GHz 6 MB processors do.
Two backplanes are available: the AB160A PCI-X 2.0 backplane with sixteen PCI-X slots, and the AD161A combination backplane with eight PCI-X and eight PCI-Express slots. One cell board enables eight slots and two cells enable all sixteen, each slot on its own bus controller and hot-pluggable. The AB314A core I/O card carries the management processor, a 1 GbE LAN port and an external Ultra320 SCSI port; one comes with the system and a second enables two nPartitions, the third and fourth internal disks and the second media bay. A Server Expansion Unit 2 adds 16 slots, four disk bays and two core I/O cards for up to 32 slots and four partitions. The card range covers Ultra320 SCSI, SmartArray, 2, 4 and 8 Gb Fibre Channel, gigabit and 10 gigabit Ethernet, InfiniBand, serial multiplexers, X.25 and combination cards.
Up to four hot-plug low-profile Ultra320 disks fit in the chassis, with 73, 146 and 300 GB 15,000 RPM drives (AD147A, AD210A, AD265A), together with two removable media bays that take the AB351B DVD+RW or the AB400A DAT 72. The operating systems are HP-UX 11i v2 and v3, Windows Server 2008, Linux (RHEL AS 4 and 5, SLES 10 SP1) and OpenVMS V8.3-1H1 or later on Montvale processors. Up to six hot-swap power supplies are fitted, two with the base and one more for each cell board, behind four C20 inlets; two cords is the minimum and four provide 2N dual-grid input, with the PCI supplies running N+1. The fully loaded reference configuration draws a typical maximum of 3,962 VA. AF916A and AF917A (60 amp) and E7681A to E7684A are the matching power distribution units, and disks, media drives and DC power supplies from the rp8400, rp8420 and rx8620 carry forward.
