/SM590000Volumes with encrypted data have a low compression ratio, and are not good candidates 
for compression. This observation is true for data that is encrypted by the host. Real-time 
Compression can provide satisfactory results for volumes encrypted by Storwize V7000, 
because compression is performed before encryption.
3.19.5  Performance monitoring
Performance monitoring must be a part of the overall IT environment. For the Storwize V7000 
and other IBM storage subsystems, the official IBM tool to collect performance statistics and 
provide a performance report is IBM Spectrum Control. 
For more information about using IBM Spectrum Control to monitor your storage subsystem, 
see this website.
Also, see IBM Spectrum Family: IBM Spectrum Control Standard Edition, SG24-8321.
