I like that you can easily get an overview over your entire infrastructure - no need for separate dashboards or programs anymore! Easy access from everywhere in my workstation (also mobile!) makes it great working with this system all day long, even when not physically located at our main office.
The price seems quite high compared to some other enterprise solutions available today but so far we haven't noticed any major drawbacks nor disadvantages using them as part of our HyperConVERGE solution. We are primarily looking into security related issues within data centers more than anything else currently; however they solve many problems by centralizing control points such us logfiles which was previously scattered throughout multiple systems & databases across several locations in different cloud environments/infrastructures around Europe - solving one issue while creating new ones.
