What is the ideal number of VS(s) I can run on 23k and 15k appliances? Each VS will run NGTX.
It will depend what will run through those VSes
And what is the reason to have VSX in first place.
I think I have seen and heard anything from handful to hundreds.
Everyone has own agenda with VSX, so really depends on your requirements
If I remember correctly the total load of a 15K or 23K device would be around the 90% of the normal max load when using VSX, however when you use a VSLS cluster, you can spread the load over the members, so when you have 3 members, you could run a total of 180% out of the 300% available (compared to a single unit) when you take into account that you need to be able to cover 1 of the boxes failing. So each would run at 60% load.
