Has anyone ever used the Performance Advisor in the NetApp Management Console to troubleshoot performance issues? If so, I'm particularly interested in anyone's comments on these two items:
Network Errors - one of the results indicated "following ifnet objects has violated Network Errors - (list of interfaces). Check the network." Talk about a nondescript error. Anyone have an idea of what this error means?
Atime Updates - this one is a lot more straightforward. The advisor recommends setting the no_atime_update option to on to improve performance. My understanding is that this option simply provides the last access time of a file, such as what you would see when viewing the properties of a file in Windows. My question is: is there any downside to turning this on? Is this option better suited to a certain type of volume, such as NFS (used as a Vmware datastore), iSCSI, and/or CIFS?
