I was at the IBM Spectrum Scale UK User group presenting over IBM Spectrum Scale security features. It is always interesting to see passionate customers advocating our product & giving direct feedback on the features which we take it very seriously. Here is the detail agenda of the UK Spectrum Scale User group : http://www.spectrumscale.org/ssug17/
