Second, it’s no a secret that the same rocket scientist created both the Cisco UCS and ACI object models. That said, the UCS PowerTool has been around for years and offers PowerShell modules that can be used to manage, operate, and automate Cisco UCS environments. As you may have guessed the Cisco ACI PowerTool is the same thing, but used to manage and automate Cisco ACI fabrics using PowerShell.

Faster speeds were fine for 4G, but 5G brings SDN into play.
Cisco network engineers might not be familiar with the multi-vendor sFlow technology since it is a relatively new addition to Cisco products. The article, Cisco adds sFlow support, describes some of the key features of sFlow and contrasts them to Cisco NetFlow.Nexus 9000 switches can be operated in NX-OS mode or ACI mode:
