Overview

Time of introduction, 2002-2003 (rx2600)/December 2004 (rx2620)

The rx2600 is the rack-designated sibling of the zx6000 workstation. They feature a very similar system design and casing and can be both mounted in 2U of a 19″ rack. Also based on one or two Itanium 2 processors the rx2600 architecture differs from the zx6000 in that it is targeted for PCI-X I/O devices and thus does not feature the AGP port of the workstation-oriented zx6000.

The rx2600 was later marketed as rx2600-2.

Prices at time of introduction,
rx2600: $7,300 (entry), $16,000 (average), $33,000 (large)

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

Chipset

The systems are based on HP’s zx1 chipset, which consists of two main components — the MIO (memory and I/O controller) and the IOAs (I/O adapters):

zx1 MIO (memory and I/O controller) is the main chipset controller and connects the three central system buses:
1. Processor bus (6.4GB/s at 200MHz DDR)
2. Two independent memory buses (each 4.25GB/s)
3. Eight I/O channels (aggregate 4.0GB/s, via the IOAs, see below)
The zx1 MIO also contains both memory and cache controllers.
Seven zx1 IOAs (I/O adapters) connect the PCI-X slots and I/O devices to the zx1 MIO with an aggregate bandwidth of 4.0GB/s on eight 0.5GB/s channels
1. PCI-X 64/133 I/O slot on two channels — 1.0GB/s
2. PCI-X 64/133 I/O slot on one channel — 0.5GB/s
3. PCI-X 64/133 I/O slot on one channel — 0.5GB/s
4. PCI-X 64/133 I/O slot on one channel — 0.5GB/s
5. Core I/O: IDE, USB, serial, (rx2600 only: Fast-Ethernet LAN) in a PCI 64/133 slot on one channel — 0.5GB/s
6. Core I/O: Gigabit Ethernet and Ultra320 SCSI (on rx2620 there are each two Gigabit Ethernet and SCSI controllers) in a PCI 64/133 slot on one channel — 0.5GB/s
7. Management: Ethernet LAN, VGA, serial in a PCI 64/133 slot on one channel — 0.5GB/s

The I/O connectivity part of the chipset is made up of standard third-party I/O chips:

Gigabit Ethernet (Broadcom 5701)
Two-channel Ultra320 SCSI controller (LSI 53C1030)
Ultra ATA-100 IDE controller (PCI649)
Serial controller, DUART (16550A-compatible)
10/100 Ethernet for management (Intel 82550)
Management processor card included by default (ECI card) — includes serial/ remote management and VGA
Radeon VGA graphics
EHCI USB controller
Processor Dependent Hardware (PDH) Controller
FPGA controller for ACPI (2.0) and LPC
Baseboard Management Controller for IPMI management interface (the BMC is a ARM7 RISC processor)

Buses

Itanium 2/zx1 processor bus 6.4GB/s at 200MHz DDR
Two independent zx1 memory buses, 266MHz, each 4.25GB/s — aggregate 8.5GB/s memory bandwidth
Eight zx1 I/O channels/buses, aggregate 4.0GB/s
Four PCI-X 64/133 I/O buses for expansion cards
Three PCI-X 64/133 I/O buses for Core I/O cards (SCSI, networking, etc.)
Two SCSI-3 Ultra320 (LVD) storage I/O buses
UltraATA-100 IDE storage I/O bus

rx2600: 24GB maximum (12×2GB)
rx2620: 32GB maximum (8×4GB — the remaining four slots cannot be used)
8.5GB/s memory bandwidth

Expansion

All PCI slots are 3.3V

Drives

Slimline bay for optional IDE CD or DVD drive

External Connectors

rx2600: Gigabit Ethernet, TP/RJ45
rx2620: Dual-Port Gigabit Ethernet, TP/RJ45
10/100 Ethernet, TP/RJ45 management network (on management processor card)
