ACI is currently outpacing NSX by about 2:1



The most recent customer figures for the two leading SDN offerings – Cisco’s ACI and VMware’s NSX – indicate that ACI is currently outpacing NSX by about 2:1. Cisco just announced its 1,000th ACI customer while VMware is currently holding fast to the 700+ NSX customer figure announced last summer.

While the figures themselves are not quite 2:1, the trajectory should reflect that NSX began shipping eight to 10 months before ACI, which started shipping in August 2014. So ACI is adding about 71 customers per month vs. 29-32 for NSX.
