Storage groups can be used to automatically replicate Packages and AppStacks and distribute Writable Volumes across multiple datastores. You can configure storage groups by using the App Volumes Manager.

You can specify a group of datastores that contain the same application packages or AppStacks and by using the vCenter, App Volumes replicates the .vmdk files across the datastores for redundancy and scalability.

Some of the attributes for the group, such as template location and distribution strategy, only apply when using the group for distributing Writable Volumes. The distribution strategy setting controls how Writable Volumes are distributed across the group.

Note: AppStacks and Writable Volumes (2. x) can be created only by using App Volumes Agent 2. x and uploading the appropriate templates. Any information related to these volumes can be viewed only when the VOLUMES (2.X) tab is visible in the App Volumes Manager UI. If you have installed the latest version of App Volumes Manager and want to explore App Volumes 2. x, see Perform App Volumes 2.x Management Tasks.

Procedure

  1. Click INFRASTRUCTURE > Storage Groups > Create Storage Group
    You can directly select the storage to add or specify a name prefix to automatically add new matching storage.
  2. Provide the following information:
    Option Description
    Group Name Name for the storage group.
    Automation
    • Select Automatically Import AppStacks and Packages
    • Select Automatically Replicate AppStacks and Packages

    The Automatically Import AppStacks and Packages option can be used to control the automatic import of new AppStacks and Packages found in the storage locations. This option does not change the import behavior of AppStacks and Packages that are replicated within the same App Volumes Manager instance. In this scenario, the volumes are always imported after replication.

    Distribution Strategy Select how you want the files to be distributed:
    • Spread - Distribute files evenly across all the storage locations. When a file is created, the storage with the most available space is selected.
    • Round-robin - Distribute files by sequentially using the storage locations. When a file is created, the storage with the oldest used time is selected.
    Template Storage Select a storage location from the drop-down menu.
    Storage Selection
    • Direct - select from the list of storage options that are displayed.
    • Automatic - You can specify a storage name prefix to filter the options. Leave the Storage Name Prefix box blank to see all storage options.
  3. Select a prefix for the storage name. Leave it blank to see all possible storage locations.
    This field is visible only for Automatic storage selection.
  4. To create a group for a specific location, select a storage location.
  5. Click Create.
  6. A list of locations that was selected is displayed. Confirm the operation and click Create..
