CHAPTER 1

General Information

This chapter provides general information about Avamar terminology, an overview of

installation features for the Avamar Data Store (ADS), and a high-level road map of the

installation.

Topics in this chapter include:

lImportant terms and concepts...............................................................................10

lInformation for customers..................................................................................... 13

lAvamar 7.x installation features overview..............................................................14

General Information 9

Important terms and concepts

This section provides a list of terms you can use to familiarize yourself with the Avamar

family of hardware. Some of these terms, since they refer to multi-node Avamar systems,

are not used anywhere else in this guide.

Nodes

The primary building block in any Avamar system is a node. Each node is a self-

contained, rack-mountable, network-addressable server that runs Avamar software on

the Linux operating system. All Avamar nodes are Domain Name System (DNS) clients.

Note

The term "server" in the previous definition is used in the typical industry context (that is,

a computer that provides services to other computers or devices). However, for the

remainder of this guide, unless otherwise specified, the term "server" is used to refer to a

single node or multi-node Avamar system. The term "node" is used to refer to the

individual computer/storage platforms that make up an Avamar server.

All nodes run the Linux operating system and use RAID data protection. Nodes have 2, 6,

8, or 12 hard drives, depending on node type and storage capacity. The primary

differences between node types are:

lThe amount of internal data storage (if any)

lHow internal data storage is configured and allocated (that is, RAID level, number of

logical units [LUNs] and so forth)

lThe Avamar application software that is installed on each node type

Utility node

In scalable multi-node Avamar servers, a single utility node provides essential internal

services for the server (for example, administrator server, replication, external

authentication, network time protocol [NTP], and Web access). Because utility nodes are

dedicated to running these essential services, they cannot be used to store backups.

Storage nodes

The remaining nodes in scalable multi-node Avamar servers are storage nodes, which

store the actual backups. There are three storage node models, the primary difference

being the amount of usable storage available: the M600, M1200, and M2400. They are

also offered as single node Avamar servers.

Single-node servers

A single-node Avamar server, whose installation is described in this guide, combines all

the features and functions of utility and storage nodes in a single node. In addition to the

three storage nodes that were mentioned previously, EMC offers another model for

single-node server usage: the Avamar Business Edition (S2400).

Extended retention media access node

The media access node exports backup data from an Avamar server to a tape library

(physical or virtual) for long-term retention purposes. It has a 10GbE port and an HBA port
