When using Centera storage, customer may experience poor Storage Expiry performance

Problem

When using Centera storage, customers may experience poor Storage Expiry performance.

Solution

Warning: Incorrect use of the Windows registry editor may prevent the operating system from functioning properly. Great care should be taken when making changes to a Windows registry. Registry modifications should only be carried-out by persons experienced in the use of the registry editor application. It is recommended that a complete backup of the registry and workstation be made prior to making any registry changes.

In the case of Centera partitions, configuring multiple threads improves the performance of storage expiry.

In Enterprise Vault 12.3 and later, you can use the following settings in the Enterprise Vault Administration Console to customize storage expiry processing:

• Maximum vault stores for concurrent storage expiry processing
• Number of threads per vault store for storage expiry processing

These settings are in the properties of the Enterprise Vault server that hosts a storage service. In Computer properties, click the Advanced tab, and list the settings for Storage to view the settings. The settings apply to storage expiry on NTFS and Centera partitions.

In Enterprise Vault 12.2 and earlier, you can use the following registry key to control the number of threads. Note that this registry setting is ignored in Enterprise Vault 12.3 and later releases.
