Table 19 Throughput totals and active sessions (continued) Field Description deduplication). These are aggregate numbers. The throughput numbers should correlate with those shown on the graphs on the Activity page. Active Sessions The right-hand column shows the number of jobs of each type that are running. NOTE: Different backup applications can use different terminology for data transfers. From a Catalyst perspective, if data is being moved between the HP StoreOnce Backup system and a media or application server, this is a data job. If the transfer is between two HP StoreOnce Backup systems, this is a Catalyst Copy job. For Copy jobs the HP StoreOnce Backup system is responsible for all data movement (although the process is initiated by the backup application software). For data jobs the backup application is responsible for the data movement. • Data Jobs running shows how many active Catalyst backup connections (for read or write) are currently active. The HP StoreOnce Backup system has the following data connections available, which are shared across all interfaces (VTL, NAS and Catalyst) and include any being used for inbound replication or inbound Catalyst Copies. HP StoreOnce VSA: 16 • Outbound copy jobs use a separate set of streams. The maximum is: HP StoreOnce VSA: 4 • Inbound copy jobs share the same pool as Data Jobs. • Client command connections are limited as follows, this number should never stay near the maximum level for any period of time. StoreOnce VSA: 8 If the copy job numbers are high (close to the maximum), no user action is required. Copy activities happen under the control of the StoreOnce Backup system and it will optimize the queuing and running of jobs based on the resources available. If the Data job count starts getting high, the HP StoreOnce Backup system is being loaded quite heavily. You may see jobs failing to start or running slowly (although the aggregate performance across the many jobs should still be high) due to insufficient resources being available. NOTE: The maximum data jobs value is not guaranteed in all cases. In some situations, such as when heavily loaded, the actual maximum may be less (based on resources available to the box at that time). StoreOnce Catalyst Settings tab The StoreOnce Catalyst Settings tab is used to view the settings that apply to Catalyst functions and jobs for all nodes on the HP StoreOnce Backup system. Users with an Admin login may also edit these settings. IMPORTANT: You must first enable Client Access Permission Checking on this page, if you wish to assign permissions when you subsequently configure clients and stores. (If you do not set permissions, all clients will be able to access all stores.) StoreOnce Catalyst page 83

Table 19 Throughput totals and active sessions

Description
Field
deduplication). These are aggregate numbers. The throughput numbers should correlate with
those shown on the graphs on the Activity page.
The right-hand column shows the number of jobs of each type that are running.
Active Sessions
NOTE:
Different backup applications can use different terminology for data transfers. From
a Catalyst perspective, if data is being moved between the HP StoreOnce Backup system and
a media or application server, this is a data job. If the transfer is between two HP StoreOnce
Backup systems, this is a Catalyst Copy job. For Copy jobs the HP StoreOnce Backup system
is responsible for all data movement (although the process is initiated by the backup application
software). For data jobs the backup application is responsible for the data movement.
•
Data Jobs running
shows how many active Catalyst backup connections (for read or write)
are currently active.
The HP StoreOnce Backup system has the following data connections available, which are
shared across all interfaces (VTL, NAS and Catalyst) and include any being used for inbound
replication or inbound Catalyst Copies.
HP StoreOnce VSA: 16
•
Outbound copy jobs
use a separate set of streams. The maximum is:
HP StoreOnce VSA: 4
•
Inbound copy jobs
share the same pool as Data Jobs.
•
Client command connections
are limited as follows, this number should never stay near the
maximum level for any period of time.
StoreOnce VSA: 8
If the copy job numbers are high (close to the maximum), no user action is required. Copy
activities happen under the control of the StoreOnce Backup system and it will optimize the
queuing and running of jobs based on the resources available. If the Data job count starts
getting high, the HP StoreOnce Backup system is being loaded quite heavily. You may see
jobs failing to start or running slowly (although the aggregate performance across the many
jobs should still be high) due to insufficient resources being available.
NOTE:
The maximum data jobs value is not guaranteed in all cases. In some situations, such
as when heavily loaded, the actual maximum may be less (based on resources available to
the box at that time).
StoreOnce Catalyst Settings tab
The StoreOnce Catalyst Settings tab is used to view the settings that apply to Catalyst functions
and jobs for all nodes on the HP StoreOnce Backup system. Users with an Admin login may also
edit these settings.
IMPORTANT:
You must first enable
Client Access Permission Checking
on this page, if you wish
to assign permissions when you subsequently configure clients and stores. (If you do not set
permissions, all clients will be able to access all stores.)
