Veritas Enterprise Vault™ Installing and Configuring

Consider what sort of sharing regime you require before you start archiving. There are limits to what you can change:

• You can change a vault store's sharing level, but the change does not act retrospectively. For example, if you change a vault store's sharing level from 'share within group' to 'share within vault store', any items already shared within the vault store group remain so.

• You cannot move a vault store to another vault store group unless all of the following circumstances apply:

  • You previously upgraded to Enterprise Vault 8.0.

  • The vault store is one that Enterprise Vault upgraded to Enterprise Vault 8.0, or one that you created in the Default Upgrade Group.

  • The vault store's sharing level is "No sharing" and has never been changed.

When deciding how to set up single instance storage, consider the following:

• You may need to keep parts of your organization separated with information barriers, also known as "Chinese walls". For example, a datacenter may be required by law or by company policy to keep information separate between its investment, retail, and mergers and acquisitions groups, to avoid conflicts of interest.

  You may want to create a separate vault store group for each organizational group in which information must be isolated.

• Network connectivity between the appropriate computers must be sufficient to provide acceptable storage and retrieval times. As a minimum we recommend that you limit single instance storage to an environment in which the connections support the expected response time of a 100 Mbps switched Ethernet LAN.

  The Enterprise Vault server whose Storage service manages a vault store must have adequate connectivity with the following:

  • The computers that host the vault store partitions for the vault stores that are within the vault store's sharing boundary.

  • The computer that hosts the vault store group's fingerprint database.

  The slower the connection speeds between these computers, the longer it takes Enterprise Vault to archive and retrieve the shared items.

  If your organization spans several widely-dispersed geographical locations it may be appropriate to create separate vault store groups for each location. Remember to locate the fingerprint databases locally.

  Enterprise Vault provides a connectivity test to estimate connection speeds across sample network connections. The relevant wizards prompt you to run the connectivity test when you create a new vault store group or partition, or when you configure sharing. The connectivity test can help you create a sharing regime with an acceptable level of performance. To assess performance, the connectivity test measures the average round-trip time for a number of ping requests. If you have disabled ping in your environment, use your own tools to decide if the performance is acceptable. We recommend a round-trip time of one millisecond or less.

  If the test results indicate poor connectivity, consider modifying the sharing boundaries or changing the location of your computers to improve connection speeds. If you are willing to accept poorer performance, you can choose to accept poor connectivity test results.

• When you create a vault store group, configure its fingerprint database appropriately for the projected sharing requirements.
