Object policy
Use the object policy page of the management interface to add, modify, and delete object policies.
Object policies are used to determine how to manage objects that go to TS7700 from an external host, such as a DS8000 as part of transparent cloud tiering (TCT). TS7700 currently allows the capability to set up copy policies for object redundancy across a TS7700 grid.
Object policies are grid scope and pertain to how an object is managed for each cluster in the grid. You can set up object policies for every object-enabled cluster in the grid by accessing this page from one of those clusters. The maximum number of object policies that can exist on a TS7700 grid is 256. If a policy does not exist on TS7700 that is object-enabled, the default object policy is used. A default object policy can be modified but cannot be deleted.
The following table describes the columns in the object policy page:
Column name | Description |
---|---|
Name | Name of an object policy. The object policy name must adhere to the following rules:
|
Description | Description of an object policy. The maximum length for this field is 280 characters. |
Object Store | Number of object stores currently assigned to a policy. |
Replication
Replication settings define how object copies are managed within a TS7700 grid. Each object-enabled cluster can be uniquely set to manage object replication differently.
The following table describes the fields in the Replication tab:
Fields | Description |
---|---|
Cluster | For each object-enabled cluster in the grid, a set of copy modes are selected. An object PUT
operation that targets the cluster follows the copy policies that are described in this
column. For instance, an object PUT operation that targets TS7700 cluster 0 performs the copy operation to itself if the cluster requires a copy, and to the other object-enabled clusters in the grid based on the policy settings configured for the target cluster. |
Copy mode | Copy mode is used when an object PUT operation is received by a cluster. It determines how
the copy is handled throughout the grid. The following are the valid types of copy mode:
