Mapping Cache Groups to Cache Groups
The Cache To Cache Map page is used to map Cache Groups to Cache Groups in a VVI. Before you can
map Cache Groups to Cache Groups, you must create them. For more information, see the “Configuring
Cache Groups” section on page 4-65.
Note The Cache To Cache Map page only displays on the VVIM. For more information, see the “Virtual Video
Infrastructure” section on page F-7.
To map Cache Groups to Cache Groups, do the following:
Step 1 Choose Configure > Array Level > Cache To Cache Map. The Cache To Cache Map page is displayed.
Step 2 From the Cache Group drop-down list, choose a Cache Group and click Select. All available Cache
Groups are displayed.
Step 3 Choose the preference setting for each Cache 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 Cache Group as a cache-fill source.
Groups with the same preference level are considered equally as a cache-fill source. At least one Cache
Group must have a preference higher than None.
Step 4 Click Submit.
