[ISE2.2] Disk size planning for keeping all profiling data

[masyamad]

I'm estimating how much disk space will be needed to keep all endpoint profiling data with ISE2.2 PSN-only node.

According to ISE old guide, 100GB is minimum space for PSN-only node.

But even if I add more disk space into PSN, the additional disk will not be used for endpoint DB.

Does it mean 100GB(or 200GB, it's recommended) is surely enough to keep all endpoint profiling data(including non-significant attribute) for the maximum 1,500,000 endpoint?

* I saw the number 1,500,000 in another community site article.

Please reference the current Install Guide.   References to ISE 1.2 is like asking about requirements on Windows 95.  ;-)

Minimum and recommended disk for PSN is 200GB.  This is sufficient to store entire endpoint DB of 1.5M endpoints.

Thanks for the info. The reason I attached older guide is that the footnote(Additional....to support local logging) disappeared on recent guides. Anyway I understand minimum disk is sufficient for 1.5M endpoints. My target version is actually 2.2. The minimum is also 200GB. Thanks!
