Storage Analytics, Monitoring and Reporting, SRM..... Whats the difference?

Hi Guys,

Over the past year, we've seen a couple of capacity/performance monitoring/reporting/trending released for the VNX.

I tried to do my research on what the difference is between Storage Analytics Suite, Monitoring and Reporting and Storage Resource Management, but i find them overlapping in ALOT of things.

All of them seem to provide:

- Capacity Monitoring

- Performance Monitoring

- Trending

How do i choose between those products? Its getting very confusing.

Thanks
