Chapter 1: DXi Advanced Reporting Introduction
About DXi Advanced Reporting
Extension to DXi
Remote Management
DXi Advanced Reporting is an extension to the DXi remote management
interface.
With DXi Advanced Reporting, you can view an array of performance
statistics for a DXi system and see how those statistics change over time.
This lets you identify trends or determine when a problem began.
By showing you how various operations affect performance, DXi
Advanced Reporting also helps you optimize the network ecosystem
and business procedures for backup, recovery, and replication.
On Demand ReportsDXi Advanced Reporting runs on a DXi system and continually works in
the background to log performance data.
To view logged data, use DXi Advanced Reporting's graphical reports.
Reports are available on demand through a Web-based interface. You
can check up-to-the-minute system status or view data for any time
period since data logging began.
DXi Advanced Reporting reports let you view and work with a wealth of
performance and system statistics, such as:
• Capacity utilization
• Ethernet and Fibre Channel activity
• Data and system disk activity
•CPU load
• Data deduplication, replication, and space reclamation activities
Each report includes one or more graphs. Use the report tools to zoom
in on a graph to see just the time period you want to see, or zoom out
to see data for a longer time period.
No matter what time period you select, all of the graphs in the report
stay in sync. In addition, DXi Advanced Reporting maintains the current
time period when you select a new report. This lets you compare
performance data between graphs in the same report or between
different reports. For example, you can see how CPU load is affected
during deduplication or space reclamation activities.
Historical DataDXi Advanced Reporting maintains approximately six years of logged
data, so you can view historical reports for any time period since
logging began—up to six years in the past.
DXi Advanced Reporting's historical record lets you compare current
performance to past performance. It also lets you see the effect of any
recent changes to system and network configuration or business
processes.
Logging Database
DXi Advanced Reporting records performance data in the logging
database. The database resides on the DXi system where DXi Advanced
Reporting is running.
See the following sections for more information about the logging
database:
• Round Robin Database
• Database Resolution
Round Robin DatabaseThe DXi Advanced Reporting logging database is a round robin style
database with a small, fixed size.
The database never grows larger than the fixed size. As new logging
data is added to the database, older data is overwritten as necessary,
thereby maintaining the fixed size. As a result, the logging database has
a negligible impact on storage capacity on the DXi system.
Database ResolutionThe logging database records performance data at two second intervals.
DXi Advanced Reporting aggregates this data over time to maintain
different resolutions for different time periods. The database resolution
is finer (more granular) for recent events and becomes coarser (less
granular) as you go back in time.
Ta bl e 1 lists the database resolutions that are maintained in the logging
database for each time period.

Performance Impact
DXi Advanced Reporting logging has a negligible impact on the
operation and performance of a DXi system.
• Most data is captured once every two seconds with a typical loop
time of only 2ms per capture.
• Total disk capacity used is limited to 2GB for the logging database.
• Disk contention is rare, and if it occurs DXi Advanced Reporting
logging has lower priority compared to system needs.
This chapter describes how to install DXi Advanced Reporting on a
Quantum DXi system and contains the following sections:
• Verifying Version Compatibility
• Setting the Date and Time
• Obtaining DXi Advanced Reporting
• Installing DXi Advanced Reporting
Verifying Version Compatibility
Before you install DXi Advanced Reporting, make sure the system
software running on the DXi is a compatible version. Look at the Home
page of the DXi remote management pages to see what version of the
DXi software is installed on the system. The software version number
appears under System Details on the Home page.
The following DXi software versions are compatible with DXi Advanced
Reporting:
• DXi2500-D - Software version 1.1.1.4_25 or higher
• DXi4500, DXi6500, and DXi7500 - Software version 1.2.1 or higher
Quantum DXi Advanced Reporting User’s Guide7
Chapter 2: DXi Advanced Reporting Installation
Setting the Date and Time
• DXi3500 and DXi5500 - Software version 1.7.3.1 or higher
If the DXi system is running an older software version, you must update
it to a compatible version before installing DXi Advanced Reporting.
Note: For help accessing the DXi remote management pages, or for
information about updating the DXi system software, see the
User’s Guide for your DXi system.
Setting the Date and Time
Because data in the DXi Advanced Reporting database is time sensitive,
it is important that the date and time are correctly set on the DXi system
prior to installing DXi Advanced Reporting.
If the date and time are not correct on the DXi system, it will be difficult
to correlate DXi Advanced Reporting data with replication activity or to
associate problems with events in the customer ecosystem. For example,
the Replication report might show a problem starting at 6:00p.m., but
because the time on the DXi system was not correct, it will not be clear
that the problem is actually associated with congestion on the network
that began at 5:00p.m.
To make sure the time and date are always correct, configure the DXi
system to use an NTP (Network Time Protocol) server. For help with this
task, see the User’s Guide for your DXi system.
Caution: Not all Windows time servers offer NTP services. If a time
server does support the NTP protocol, you cannot use it as
a time source for DXi system. However, in this case, a third
party NTP application for Windows should work correctly.
