The rx1600 (later rx1600-2) is a 1U rack-mountable server with up to two Itanium 2 Deerfield processors. The later introduced rx1620 supported newer Fanwood Itanium 2 processors. Both classes of CPUs are specified/marketed as low-voltage.

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

Chipset

The systems are based on the HP zx1 chipset with two central components — Pluto and Mercury.

Pluto: main chipset controller connects to three system buses:
1. Processor bus
2. Two independent memory buses
3. Seven I/O channels
It contains both memory and cache controllers as well.
Five Mercury I/O adapters: connect PCI-X slots and I/O devices to Mercury
1. PCI-X 64/133 slot on two channels with 1.0 GB/s
2. PCI-X 64/133 slot on two channels with 1.0 GB/s
3. Gigabit Ethernet and Ultra320 SCSI (Core I/O) on PCI on one channel with 0.5 GB/s
4. IDE, USB, Fast-Ethernet LAN (Core I/O) on PCI on one channel with 0.5 GB/s
5. Management Ethernet LAN, VGA, serial (Core I/O) on PCI on one channel with 0.5 GB/s

The remained consists of standard third-party I/O chipsets:

Gigabit Ethernet (Broadcom 5701)
rx1600: Fast Ethernet
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
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)
EHCI USB controller

System buses

Itanium 2/zx1 processor bus — 200 MHz DDR with 6.4 GB/s bandwidth on 1.0 and 1.3 GHz processors, 266 MHz DDR with 8.5 GB/s on 1.6 GHz processors (rx1620)
Two independent zx1 memory buses, 266 MHz, each 4.25 GB/s — aggregate 8.5 GB/s memory bandwidth
Seven zx1 I/O channels/buses, aggregate 3.5 GB/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

Memory

PC2100 ECC DDR CL2 SDRAM DIMMs
Takes up to 2 GB modules
Eight slots
DIMMs must be installed in quads
1 GB minimum (4×256 MB)
16 GB maximum (8×2 GB)
8.5 GB/s memory bandwidth

Expansion slots

PCI-X 64-bit/133 MHz slot, full-length
PCI-X 64-bit/133 MHz slot, half-length
All PCI slots are 3.3 V

rx1600: 10/100 Ethernet, TP/RJ45
rx1620: Second Gigabit Ethernet, TP/RJ45
10/100 Ethernet, TP/RJ45 management network (on management processor card)
VGA graphics
Ultra320 SCSI 68-pin HDCI
25-pin serial for management processor card, needs break-out cable for three serial ports
Two USB 2.0 ports
Two serial RS232C DB9

Operating systems
