Clariion Performance

Can you provide more information about what specific details you need?  For Solaris, iostat has a vast array of detail, on every version of Solaris.  My preference is iostat -xMnz 1, which reports extended statistics every second, including I/O queue length (wait), active I/Os and so forth.

Thanks, i'll try iostat.

I was thinking of tools at the array level.

Clariion has a performance tool called Navisphere Analyzer (or Unisphere Analyzer if you it is running FLARE 30+).  In order to use Analyzer it must be licensed, and data logging enabled.  You can launch Analyzer right from Navisphere Manager and do real-time analysis or open archives of data to look at hours or days at one time.   Analyzer is somewhat clunky sometimes but extremely powerful for a midrange storage system.

If you don't have a license, you can still log data, (FLARE22 and higher I believe) and EMC pre-sales or Support can look at the data.  Pre-sales does a good job of helping give you an overview of what's going on, while support can diagnose performance problems.

Performance metrics with EMC gear can be a little interesting.  I look at performance metrics or monitoring in two different distinct ways.

1) Performance Trending & Performance Analysis - This is historical in nature and is best used for capacity planning or after incident performance analysis.  NaviSphere Analyzer is great for that.

2) Performance Alerting & Monitoring - This is for when you want to know about issues when they are issues, or ahead of the fact.  NaviSphere Analyzer is very bad for that.  For something like that look at Solarwinds Storage Profiler or Manage Engine OpStor (my favorite).
