思科ACS的性能总结

ACS Performance & Scale

思科ACS目前还能支持的可能就是ACS5.8版本了，该版本也将于2020年停止支持，关于ACS信息会逐步退出大家的视野。该文档是Cisco论坛thomas在2016年总结的。个人感觉非常有用。

ACS Hardware Platforms

VMs must have the equivalent of the hardware platforms or better.

VM resources must be dedicated to ACS and not shared with other VMs.

ACS TACACS+ Performance

SNS-34xx and 35xx appliance performance was done with ACS 5.8 patch 1 as a dedicated authentication node.

Recommend dedicating resources for VM performance equivalent to hardware.
