About SAN Headquarters
SAN Headquarters (SAN HQ) is a performance-monitoring tool that enables you to monitor multiple PS Series groups from a single
graphical user interface (GUI).
SAN HQ gathers and formats conguration and performance data into easy-to-view charts and graphs. Analyzing this data can help
you improve performance and more eectively allocate group resources.
SAN HQ allows to you deploy Dell SupportAssist for diagnostic data collection on a weekly basis, on-demand as needed, or when
critical events occur. Diagnostic data collections are automatically uploaded to Dell Technical Support for analysis, unless you disable
automatic uploads. In that case, the data is encrypted and stored locally.
By default, Group Manager displays an Action alarm in the Alarms and Operations panel in the lower part of the window whenever
SAN HQ is not monitoring the group.
Using SAN HQ, you can:
Quickly be informed of problems related to hardware, capacity, and performance
Improve performance by identifying performance bottlenecks
Obtain comprehensive information about group performance based on latency, IOPS, I/O rate, I/O size, and other data. Using
95th percentile reporting, remove the top 5 percent of spikes in data for a more accurate picture of your storage performance.
View real-time data for group member or volume I/O and save the results for future analysis
From a single SAN HQ client, monitor group performance data from multiple servers
Determine how the group is performing, relative to a typical I/O workload of small, random I/O operations. This information can
help you determine if a group has reached its full capabilities, or whether you can increase the group workload with no impact on
performance.
Display performance-based load-balancing data for the group (the default), for all pools on the group, or for all members in the
group.
For a selected group, pool, or member, apply dierent RAID policies and analyze the performance benets
View events, audits, and group alerts
More eectively allocate group resources by identifying underutilized resources
Enable multiple individuals to access and monitor the same performance data
Preserve group performance data for later analysis by creating archives
Create customized reports of group performance data
Export group performance data to a spreadsheet
Specify favorite views
Visualize synchronous replication volumes and NAS containers
Display space consumed by recoverable volumes in the recovery bin
Display space available for snapshot borrowing
See the number of Ethernet ports with active and inactive data center bridging (DCB), and the number of ports incompatible
with DCB

User’s Guide.
Manage SAN Headquarters Action Alarm
In Group Manager, the SAN Headquarters (SAN HQ) section of the Group Conguration General panel lists servers from which SAN
HQ is currently monitoring or had previously monitored the group.
By default, if no SAN HQ server is currently monitoring the group, the Alarms and Operations panel at the bottom of the Group
Manager GUI displays an Action alarm.
To hide the alarm and congure Group Manager to never display a SAN HQ monitoring alarm in the future:
