In order to improve performance, an Enterprise Vault server that retrieves files from an EMC Celerra device requires a location to use for temporary files.
Before you add the first volume on a Celerra device you must specify a folder that is local to the Enterprise Vault server that can be used for caching temporary files.
To specify a cache location
In the Administration Console, expand the Enterprise Vault site until the Enterprise Vault Servers container is visible.
Right-click the server that will archive from the Celerra and, on the shortcut menu, click Properties.
Under Cache Location, enter an existing path on the server that can be used to cache files retrieved from the Celerra.
