Note: Click a column heading to sort the rows in the table by that
column. Click the column heading again to reverse the sort
order.
Note: The connections of a storage server that are used equals the
data streams plus one for each LSU 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 a Storage Server
Add a storage server to present the storage capacity of the DXi4701 as
LSUs that are compatible with backup applications that support OST.
You can add up to 100 storage servers. When adding a storage server,
you must also add an LSU to the storage server. (For more information
about LSUs, see LSU on page 273.)
Note: Data on storage servers is always deduplicated.
