Mapping Vault Groups to Cache Groups
The Cache To Vault Map page is used to map Vault Groups to Cache Groups in a VVI. Before you can
map Vault Groups to Cache Groups, you must create them. For more information, see the “Configuring
Cache Groups” section on page 4-65 and the “Configuring Vault Groups” section on page 4-61.
Note The Cache To Vault Map page only displays on the VVIM and is available only when Vault Groups and
VVI are both enabled. For more information, see the “Bulk Configuration” section on page F-5 and the
“Virtual Video Infrastructure” section on page F-7.
To map Vault Groups to Cache Groups, do the following:
Step 1 Choose Configure > Array Level > Cache To Vault Map. The Cache To Vault Map page is displayed.
Step 2 From the Cache Group drop-down list, choose a Cache Group and click Select. All available Vault
Groups are displayed. By default, all preferences are set to None.
Step 3 Choose the preference setting for each Vault Group. Following are the possible preferences:
• High—First preference as a source for cache-fill requests.
• Medium—Second preference as a source for cache-fill requests.
• Low—Lowest preference as a source for cache-fill requests.
• None—Do not use this Vault Group as a cache-fill source.
Groups with the same preference level are considered equally as a cache-fill source. At least one Vault
Group must have a preference higher than None.
Step 4 Click Submit.
