The ease of use, quick deployment times (even with my limited technical skills). It has been easy to integrate our Cisco UCS B-series servers into this solution as well which was not possible previously using other DCI solutions we used in previous environments at that time! Not much dislike but I wish there were more options available when it comes down selecting what hardware components need installed within each chassis or rack so you don't have too many different configuration screens/options etc - would be great if they could add some sorta "check all" button like option where everything gets checked automatically? This makes life easier by only having one screen per system instead requiring multiple configs across several systems from another product line such as HPE Procurve Network Manager Control Center / NMC CTM software suite. We are able solve issues around network connectivity between devices via VPN tunnels without.
