It seems ProSphere is much, much, much more limited than ECC, specifically in terms of host and the ability to report on hosts. I prefer the ProSphere interface, but that's where it ends. I want ECC level reporting and alerting available in ProSphere. We use ECC to monitor file system capacity/usage, and that isn't available in ProSphere. Isn't monitoring the actual USED capacity or your storage, as based by host/user usage a significant portion of storage management?
