Chapter 1: Introduction; Data Domain System Types - Data Domain DD580 System Hardware Manual

Introduction
The main differences between Data Domain systems are the throughput and the amount of data
storage capacity. Data Domain Gateway systems store data on external disk arrays through a Fibre
Channel connection.

Data Domain System Types

Data Domain systems have model numbers. The gateway version of a Data Domain system has the
same model number as the non-gateway version, but with the suffix g.
Data Domain Systems belong to one of the following sets. Every model in each set uses the same
motherboard and chassis. Installation, interface locations, and PCI slots are different for each set.

Domain Expansion Shelf Hardware Guide.
Table 1 on page 12 lists the capacities of the Data Domain systems. Data Domain system internal
indexes and other product components use variable amounts of storage, depending on the type of
data and the sizes of files. If you send different data sets to otherwise identical systems, one system
may, over time, have room for more or less actual backup data than another.
Note Data Domain system commands compute and display amounts of disk space or data as
decimal multiples of certain powers of two (2
of disk space = 7 x 2
as base 2 calculation.
