DSView 3 software hub server

A DSView 3 software hub server is responsible for maintaining the master copy of the DSView 3 software system database. Only one server in a DSView 3 software system can be configured as the hub server. Spoke servers in a DSView 3 software system perform database replication with the hub server. The DSView 3 software hub server acts as the traffic cop for database replication between itself and all of the other servers in a DSView 3 software system.

The DSView 3 software hub server and a spoke server offer the same software functionality to a user. The distinction of hub or spoke only has to do with the database replication role the server plays and not with the software functionality the server offers to the user.

The DSView 3 management software versions of the spoke server and hub server must match in order to register the spoke server. For example, you may not register a spoke server running DSView 3 version 3.1 with a hub server running DSView 3 software version 3.2.

DSView 3 software spoke server

A DSView 3 software spoke server is responsible for initiating database replication with the hub server. A spoke server sends its database changes to the hub server and receives database changes from it.

The DSView 3 software hub server and a spoke server offer the same software functionality to a user. The distinction of hub or spoke only has to do with the database replication role the server plays and not with the software functionality the server offers to the user.

The DSView 3 management software versions of the spoke server and hub server must match in order to register the spoke server. For example, you may not register a spoke server running DSView 3 software version 3.1 with a hub server running DSView 3 software version 3.2.

DSView 3 software system

A DSView 3 software system includes all the components required to provide DSView 3 software functionality, including the DSView 3 server, DSView 3 software client, managed appliances and target devices.

An SNMP manager and external authentication servers, which are optional components and outside the DSView 3 software system, may also be added to provide additional functionality.

Embedded appliance

Embedded appliances include IBM ASM RSA II, DRAC 4, HP iLO and NEC IPF embedded appliances.

Encryption

Encryption is the translation of data into a secret code. Encryption is the most effective way to achieve data security. To read an encrypted file, you must have access to a secret key or password that enables you to decrypt the file. Unencrypted data is called plain text. Encrypted data is referred to as cipher text.

There are two main types of encryption: asymmetric (also called public-key encryption) and symmetric.
