Number of PSN node and pxGrid Node in Large ISE Deployment

[SaintEvn]

Hi,

In Large Cisco ISE Deployment , all the personas are dedicated and it can support 2 PAN nodes , 2 MnT nodes and up to 50 PSN nodes. So a total of 54 nodes.

It also said that it can support up to 4 pxGrid nodes.
What I want know is if I used 4 pxGrid in my deployment , the total number of PSN supported will become 46 right? Because 4 nodes from the PSN will be used as pxGrid? 

Thank you so much!

That is correct, If you were to deploy 4x PXG, you would want to stay under 46x PSN persona nodes.
