I have been a user of STOR2RRD since ~2012 I think. It is a brilliant tool to gather historical performance information on your IBM San Volume Controller based storage (Storwize, SVC, etc).
However, I was looking for a new version few days ago and saw that they have added support for HP 3PAR. They also added support for some HDS storage as well as NetApp. So now, if you cannot cough up dough for [insert your best-of-breed storage management tool here] you might have a cool alternative there 🙂
Of course, this is no replacement for IBM’s TPC products but if you are looking for a single tool to gather performance statistics for your storage arrays and your Brocade fabrics, look no further. This is a very valuable tool to use in daily operations.
