Overview

Time of introduction: 2004 (rx1600)/December 2004 (rx1620)

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

Prices at time of introduction: started at under $3,000 (rx1600)/$4,000 (rx1620)

CPU

rx1600/rx1600-2

No.	CPU Type	Clock	L1 (I/D)	L2 (I/D)	L3
1-2	Itanium 2 Deerfield low-voltage	1.0GHz	16/16KB	256KB	1.5MB

rx1620

No.	CPU Type	Clock	L1 (I/D)	L2 (I/D)	L3
1-2	Itanium 2 Fanwood low-voltage	1.3GHz	16/16KB	256KB	3.0MB
1-2	Itanium 2 Fanwood low-voltage	1.6GHz	16/16KB	256KB	3.0MB

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 on 1.0 and 1.3GHz processors, 8.5GB/s on 1.6GHz processors)
2. Two independent memory buses (each 4.25GB/s)
3. Seven I/O channels (aggregate 3.5GB/s, via the IOAs, see below)
The zx1 MIO also contains both memory and cache controllers.
Five zx1 IOAs (I/O adapters) connect the PCI-X slots and I/O devices to the zx1 MIO with an aggregate bandwidth of 3.5GB/s on seven 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 two channels — 1.0GB/s
3. Gigabit Ethernet and Ultra320 SCSI (Core I/O) on PCI on one channel — 0.5GB/s
4. IDE, USB, Fast-Ethernet LAN (Core I/O) on PCI on one channel — 0.5GB/s
5. Management Ethernet LAN, VGA, serial (Core I/O) on PCI 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)
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

Buses

Itanium 2/zx1 processor bus — 200MHz DDR with 6.4GB/s bandwidth on 1.0 and 1.3GHz processors, 266MHz DDR with 8.5GB/s on 1.6GHz processors (rx1620)
Two independent zx1 memory buses, 266MHz, each 4.25GB/s — aggregate 8.5GB/s memory bandwidth
Seven zx1 I/O channels/buses, aggregate 3.5GB/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 2GB modules
Eight slots
DIMMs must be installed in quads
1GB minimum (4×256MB)
16GB maximum (8×2GB)
8.5GB/s memory bandwidth

Expansion

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

Drives

Two internal 3.5″ bays for 1″ height Ultra320 SCSI SCA 80-pin hard drives, hot-plug; drives 1 and 2 are on one SCSI channel, drive 3 on the second SCSI channel
Slimline bay for optional IDE CD or DVD drive

External Connectors

Gigabit Ethernet, TP/RJ45
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 DB9 male RS232C serial
