Stratus® ftServer® W Series 2300
Technical Reference Guide
Revision 1 – 10/28/04
1. Overview
The Stratus® ftServer® W Series 2300 system is based on Intel® IA32 architecture using Intel’s
Xeon Prestonia processor in a dual modular redundancy (DMR) configuration.
Each W Series 2300 system has two CPU elements and two I/O elements combined on a 16X20inch motherboard in a 4U (7-inch) standard 19-inch rack-mountable unit (can be converted to a
pedestal system). The CPU element is configured to support a front side bus (FSB) of 533 MHz
with a CPU speed of 3.06 GHz.
Each I/O element has two user configurable 33-Mhz/64-bit PCI slots. Optional Virtual
Technician Modules (VTMs) may be installed in the system to enhance the system’s remote
management functionality. This VTM is a PCI adapter that is installed in a 168-pin DIMM
connector. It uses a dedicated serial port.
The embedded features include a 10/100/1000 Mbit PCI Ethernet controller, a PCI Video
controller, and a PCI SATA controller.
The figures on the following page show the front and rear components of the W Series 2300
system.

3.1.2 I/O Element
Each I/O element contains an embedded four-channel SATA controller supporting up to 3 SATA
disks. Channels 0-2 are connected to the SATA backplane and channel 3 is terminated (not
used).
Each I/O element also contains two user PCI slots (64bit/33MHz) and a dedicated VTM slot.
3.1.2.1 PCI Adapters
The W Series 2300 has two user configurable slots per I/O element.
The following table describes the specific adapters that can be configured in W Series 2300
systems. The table also includes the minimum and maximum number of adapters supported.

3.2 SATA Backplane Board
3.2.1 Disk Drives
The W Series 2300 system contains two SATA backplane assemblies, one per I/O element. Each
backplane can hold up to three SATA compliant drives.
A minimum of two internal disk drives is required. Disk drives are mirrored to the
corresponding drive bay of the partner IO element.
The following table lists the disk drive supported in W Series 2300 systems.
Model Description
D641 80-GB, 3.5”, 7200 RPM, SATA Disk Drive
D642 160-GB, 3.5”, 7200 RPM, SATA Disk Drive
The boot disk should be the smallest size available. It is required that the boot disk be installed in
the topmost drive bay (SATA channel 0).
The following table lists the internal disks and corresponding SATA-IDs.
SATA Channel 0 DISK 0 (DXXX)
SATA Channel 1 DISK 1 (DXXX)
SATA Channel 2 DISK 2 (DXXX)
Page 6
When configuring mirrored internal disk drives, refer to the SATA channel numbers for the
drives shown next to the disk drives in the table.
3.3 Common IDE Board
The IDE board supports the CDROM or DVD/CDROM drive. It’s connected to the motherboard
via a 40-pin flat ribbon cable.
3.4 Front Panel (LED) Board
