10.4 OST Configuration
Description (Optional) Enter a brief description of the storage server.
Max
Connections Enter the maximum number of connections allowed to the storage server
(3 to 65536)
Fujitsu Technology Solutions recommends setting Max Connections to
300.
Enable
Concurrent
Optimized
Duplication 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 ETERNUS CS800. 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.
To configure the target ETERNUS CS800,
When Concurrent Optimized Duplication is enabled, all data on the
storage server is duplicated, not just the specified images.
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 (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.
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 "Deleting a Storage Server" on page
251 ).
