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 ETERNUS CS800 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 251 .)
