About Enterprise Vault services in building blocks configurations

In a building blocks configuration, each Enterprise Vault server operates as a discrete unit providing the following Enterprise Vault functionality for a particular set of users:

  • Archiving and retrieval of data. Each building blocks server includes a Directory service and the required archiving tasks and services.

  • Storage of data. Each building blocks server includes a local Storage service. The storage and index files must be stored on a file system that is shared with the associated building blocks servers.

  • Web access. Each building blocks server includes the Web Access application, which provides users with an interface to search and retrieve archived items. This can only be accessed correctly if there is a non-specific URL in the site properties, for example, /EnterpriseVault

The failover functionality of building blocks (Update Service Locations) passes the duties of the failed server to another building blocks server. If a required service or task does not yet exist on the new active server, then Update Service Locations creates it.

The building blocks system also contains a number of shared system components. These include the following:

  • SQL databases for directory and archive data. These are typically deployed on a dedicated SQL server, allowing the inherent scalability and high availability features of SQL to be fully exploited.

  • Centralized storage. Vault store partition data and index locations are shared by each of the building blocks servers.

A building block server may or may not include an Indexing service, depending on the indexing configuration used. The following indexing configurations are supported in building blocks:

  • Both the active and failover servers are Index Servers that belong to the same Index Server Group.

  • Both the active and failover servers are ungrouped Index Servers.

  • Neither the active nor failover servers host an Indexing service.

  • The active server is an ungrouped Index Server, and the failover server does not host an Indexing service. On failover, an ungrouped Indexing service is created on the failover computer.

Note:

If the active server hosts an Indexing service, then the failover server must have an Enterprise Vault server cache configured.

For an introduction to Index Servers, Index Server Groups and Enterprise Vault building blocks, see Introduction and Planning.

The planning of building block configurations is beyond the scope of this manual. Contact your Symantec solution provider if you need a highly-available installation of Enterprise Vault.
