[gpfsug-discuss] Encryption - guidelines, performance penalties?

[Oesterlin, Robert]

There are a number of good guides and Redbooks out from IBM that talk about the implementation of encryption in a Spectrum Scale (GPFS) cluster. What I’m looking for are other white papers, guidelines, reference material on the sizing considerations. For instance, what’s the performance overhead on an NSD server? If I have a well running cluster today, and I start using encryption, will my NSD servers need to be changed? (more of then, more CPU, etc)

And references material or practical experience welcome.
