Backup applications generally create a small number of additional files during a backup job in
order to store configuration details and catalog entries. Some of these small files will generally be
updated throughout the backup process and, in most instances, these files will be below the
deduplication threshold. So, there is also a maximum number of open files that are the same size
or smaller than the deduplication threshold that are allowed per appliance.
Across the whole HP StoreOnce Backup System the number of simultaneously open files is as
follows:

Maximum number of users per CIFS share
The maximum number of users that may be configured when using “user” or AD authentication for
access to a CIFS share is 50. This maximum is the total number of users per CIFS server and also
the maximum that can be allocated access to any single CIFS share
Different users may access single NAS shares simultaneously, however, a file within a share may
only be opened by one user at a time.
Maximum number of hosts per NFS share (G3 and G2 products only)
The maximum number of host systems that may be configured to access an NFS share is 50.
This maximum is the total number of hosts per NFS server and also the maximum that can be
allocated access to any single NAS share. A file within a share may only be opened by one user
at a time.
18 NAS shares
