The HP Integrity rx5670 are rack-mountable multi-processor Itanium 2 servers with up to four processors. Closely matching the rx4640 system architecture, the rx5670 is based on HP’s zx1 Itanium chipset. PA-RISC L-Class servers (built into the same system/chassis) could be upgraded by a board-swap — changing the main system board, processors and support hardware — to Itanium 2 rx5670s (applies to HP rp5400/rp5450 (L1000/L2000) and HP rp5430/rp5470 (L1500/L3000)).

System architecture

Processors

No.	CPU Type	Clock	L1 (Instruction/Data)	L2 (Instruction/Data)	L3
1-4	Itanium 2 Madison	1.3 GHz	16/16 KB	256 KB	3.0 MB
1-4	Itanium 2 Madison	1.3 GHz	16/16 KB	256 KB	6.0 MB

All caches are on-die (L1, L2 and L3).

Chipset

The rx5670 is based on HP’s zx1 chipset, which consists of three main components — the MIO (memory and I/O controller), the IOAs (I/O adapters) and the SMEs (scalable memory expanders):

Pluto zx1 MIO (memory and I/O controller) is the main chipset controller and connects the three central system buses:
1. Processor bus (6.4 GB/s at 200 MHz DDR)
2. Two independent memory buses (each 6.4 GB/s with six SMEs)
3. Eight I/O channels (aggregate 4.0 GB/s, via the IOAs, see below)
The zx1 MIO also contains both memory and cache controllers.
Twelve zx1 SMEs (scalable memory expanders), six on each DIMM/memory carrier board, attach to two independent zx1 memory buses (each 6.4 GB/s)
Eight Mercury zx1 IOAs (I/O adapters) connect the PCI-X slots and I/O devices to the zx1 MIO with an aggregate bandwidth of 4.0 GB/s on eight 0.5 GB/s channels
1. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
2. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
3. PCI-X 64/133 I/O slot on one channel — 0.5 GB/s
4. Two PCI-X 64/66 I/O slots on one channel — 0.5 GB/s
5. Two PCI-X 64/66 I/O slots on one channel — 0.5 GB/s
6. Two PCI-X 64/66 I/O slots on one channel — 0.5 GB/s
7. One PCI 64/66 slot for Gigabit Ethernet and one SCSI controller (Core I/O) on one channel — 0.5 GB/s
8. One PCI 64/66 slot for management LAN, serial and one SCSI controller (Core I/O); and
  one PCI 64/33 slot for optional graphics/USB on one channel (with the other slot) — 0.5 GB/s

The rest are standard third-party I/O chips, implemented on Core I/O cards in two or three PCI slots
