polling. A backup job may generate more than one data stream if the data can be read in parallel. For
example, a policy that is backing up A, B, C, and D drives of a Windows system can generate four data
streams in parallel.
Adding an LSU
Add an LSU to a storage server to present the storage capacity of the DXi4700 as an LSU that is compatible
with backup applications that support OST. You can add an LSU with a specific capacity, or you can add an
LSU that uses the available capacity of the DXi4700.
Note: You must create a storage server before you can add an LSU (see
page 236).
To add an LSU to a storage server:
