Netapp

I have spent a lot of time with various vendors support departments; and I have to say, Netapp has one of the best support departments.  If I call Netapp at 2:00 AM on a Sunday morning, I can get someone on the phone right away.  My one complaint is that I cannot open a ticket via E-Mail.  Fortunately that is not a big hurdle to cross.

When you are working with Netapp support you can either open a ticket over the phone or via the Now website.  If you do not have a NOW login, I would recommend getting one.  The NOW site is what will give you access to Netapp Documentation, Updates for your Filer, performance metrics from your Filer, and access to the support Portal.

When troubleshooting performance issues on a Netapp storage system, Perfstat is a very useful utility.  There are other ways to get performance statistics, but they are not quite as detailed.

The perfstat file at first glance can be rather daunting.  Perfstat files get very large, very fast, and may scare away the faint at heart.  But, if you spend a little time looking them over, they start to make some sense.

For the purpose of this article I am going to focus on three areas which will help you to pinpoint the performance problem you be experiencing on your SAN; these areas are Disk, CPU, and Network.
