tacacs performance sizing maximun 2.6

[mpeeters]

I am engaged with a SP opportunity for tacacs AAA with command tracking (accounting) for 1 M devices for later calender 2019. I understand that ise 2.6 may not support this many devices. Looking for the current max.

deployment will be vm based. large vm for the pan (P/S) and M&T (P/S).  34 med vm for psn ( tacacs only).

what are the max devices (nads) per deployment ?

What is the max peak and sustained TPS for the deployment.

Thx
