GLYPH<SM590000> Volumes 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 3.20 Storage Insights 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. Storage Insights is an integral part of the monitoring and ensuring continued availability of the  Storwize V7000. Available at no charge, cloud-based IBM Storage Insights provides a single dashboard that  gives you a clear view of all your IBM block storage. You can make better decisions by seeing  trends in performance and capacity.  Storage health information enables you to focus on areas needing attention and when IBM  support is needed, Storage Insights simplifies uploading logs, speeds resolution with online  configuration data, and provides an overview of open tickets all in one place. Storage Insights includes the following features: GLYPH<SM590000> A unified view of IBM systems: – Provides a single pane of glass tosee all your systems characteristics. – See all of your IBM storage inventory. – Provides a live event feed so you know, up to the second, what is going on with your  storage and enables you to act quickly. GLYPH<SM590000> Storage IBM Insightfi collects telemetry data and call home data and provides. GLYPH<SM590000> Overall storage monitoring looking at: – The overall health of the system. – Monitor the configuration to see whether it meets the best practices.  – System resource management; that is, is the system being overly taxed and provide  proactive recommendations to fix it. GLYPH<SM590000> Storage Insights provides advanced customer service with an event filter to that allows: – The ability for you and support to view supp ort tickets and open and close them and to  track trends.  – Auto log collection capability to allow you tocollect the logs and send to IBM before  support start looking into the problem. This feature can save as much as 50% of the  time to resolve the case. Up to the second system reporting of capacity and performance. Chapter 3. Planning  83
