6 Analyzing Dell PS Series Storage with SAN Headquarters | TR1050
1 SAN Headquarters overview
SAN Headquarters (SAN HQ) is a client/server application that runs on Microsoft
®
Windows Server
®
. It monitors one or
more PS Series groups and uses SNMP to query the groups. SAN HQ collects data over time and stores it on the server
for retrieval and analysis. The client connects to the SAN HQ server, formats and displays the data in the graphical user
interface (GUI). Analyzing this data can assist in making decisions to improve performance, reliability, and allocation of
resources.
In addition, SupportAssist is included with SAN HQ to provide diagnostic collection, upload, and analysis of PS Series
arrays.
SAN HQ provides the following functions:
Performance
• Improve performance by identifying bottlenecks.
• Obtain comprehensive information about group performance based on latency, IOPS, I/O rate, I/O size, and
other data.
• View real-time data for group member or volume I/O and save the results for future analysis.
• Quickly be informed of hardware-, capacity-, and performance-related problems.
• Monitor group performance data from multiple servers from a single SAN HQ Client.
Operations
• Allow multiple administrators to access and monitor the same performance data.
• Configure the SAN HQ Server to send SNMP notifications to an SNMP management console.
• Display Dell customer support cases created from SupportAssist diagnostic uploads and traditional support
calls.
• Launch the Dell Storage Update Manager tool to update controller firmware, disk-drive firmware, and
language packs.
• Obtain an automatic weekly update of the SAN HQ local repository, including newly supported disks and
hardware, used for estimated IOPS calculations. This local repository is also used to verify member
configuration and disk-drive support. You can also choose to update the local repository manually at any time.
• View 512 byte or 4 Kb disk sector size for each disk per member and for each volume in the group.
• Display space consumed by recoverable volumes in the recovery bin.
• Report delegated space for replication allocated by a secondary group to a primary group in multiple pools.
