3. Select the check box for each optimized duplication target you want to duplicate the storage server to.
When the storage server is duplicated, its data will be sent to all selected targets.
4. Under Logical Storage Unit, select the type of LSU to add to the new storage server:
Available Capacity
Quantum DXi6900 User's Guide
Enter the name of the storage server.
Caution: Do not use an underscore ( _ ) in the name of the storage
server.
Note: OST storage server names are not case-sensitive. For
example, if you create a storage server named ost1, you cannot
create another storage server named OST1 because the system
considers the names to be the same.
(Optional) Enter a brief description of the storage server.
Enter the maximum number of connections allowed to the storage server
(3 to 65536)
Quantum recommends setting Max Connections to 300.
Select the check box to enable optimized duplication during OST ingest.
Concurrent Optimized Duplication is disabled by default. If enabled, as
data is written to the storage server, it is simultaneously replicated to the
target DXi. When optimized duplication or Automatic Image Replication
subsequently occurs, the operation is more efficient because a portion of
the required data has already been replicated to the target storage server.
Note: To configure the target DXi, see
on page 270.
Note: When Concurrent Optimized Duplication is enabled, all data on
the storage server is duplicated, not just the specified images.
(Recommended for best performance) Select this option to add an LSU that
uses the available capacity on the system.
You cannot add an available capacity LSU to a storage server that already
contains an LSU. Also, if you add an available capacity LSU to a storage
server, you cannot add additional LSUs to that same storage server.
Note: After you add an LSU that uses the Available Capacity option,
you cannot change the LSU to use the Specific Capacity option.
Instead, you must delete the LSU, then add a new LSU and choose the
Specific Capacity option (see
Adding a Replication Target
Deleting an LSU on page 261).
