Overview 1-1
Chapter 1
Overview
The AlphaServer GS80, GS160, and GS320 systems are high-performance
server platforms designed for enterprise-level applications. They are
distinguished by their versatility and high degree of scalability and
expandability.
These powerful, switch-based systems use four Alpha microprocessors per quad
building block (QBB). Two QBBs paired back-to-back and rotated 1800with
reference to each other form a system box. Each QBB backplane contains a
switch that acts as an interconnect between the CPU modules, memory
modules, I/O riser modules, and the global port module.

1-2 AlphaServer GS80/160/320 Site Preparation
1.1 The Systems
The GS80 is a rack system whereas the GS160 and GS320 are box-based
systems.
1.1.1 GS80 System
The GS80 system is contained in a single cabinet. It is a drawer-based system
consisting of one or two drawers. Each drawer contains one QBB with up to
four CPU modules and up to four memory modules. In a two-drawer system a
distribution board connects the two QBBs through their global ports.
The system cabinet of the GS80 also contains the power supplies and
accommodates one PCI box, a storage shelf, and the OCP (operator control
panel). An expander cabinet can house additional PCI boxes and storage
shelves.
1.1.2 GS160/320 System
The GS160/320 system consists of a power cabinet and one system cabinet
(GS160) or two system cabinets (GS320), depending on the configuration. The
power cabinet contains the power supplies, the I/O components—the PCI boxes
and storage units—and the OCP. The system cabinets house the system boxes
that carry interconnect modules as well as CPU and memory modules.
The system cabinet can be configured with one or two system boxes. The first
system box is located in the lower cavity of the cabinet and the second system
box is inserted in the upper cavity. A fully configured system consists of a
power cabinet and two system cabinets—system cabinet 1 and system cabinet
2—each system cabinet containing two system boxes.
In a single system box system a distribution board interfaces the two QBBs
directly through their global ports. In configurations with more than one
system box a hierarchical switch replaces the distribution board and adds a
second level switch to route information between the system boxes.
Additional PCI boxes and storage shelves can be accommodated in expander
cabinets that can be attached to either side of the system.
