1 Combining Flash with Predictive Analytics to Reduce Business Risk Nick Triantos MES Fall September 2017

2 Business Impact is Severe Apps Data

3 Endless Fire-fighting with Lost Nights and Weekends Reacting to unexpected problems Trying to interpret dozens of graphs and logs Calling vendor support adds to the frustration High stress, wasted time, and business impact

4 Don t Settle on the Way It Has Been Cloud Based Analytics Rich Telemetry Global Learning FUTURE TODAY

5 Collecting and Analyzing Millions of Sensors per Second Cloud based Predictive Analytics VM/Container/DB Compute Network Storage Cross-Stack Telemetry Global Learning

6 Overcoming Complexity and Eliminating Anxiety Predicts and prevents problems Global visibility and learning Support you actually like 86% Issues automatically opened and solved > % Measured availability 54% Cases solved outside of storage

7 Overview of InfoSight Capabilities

8 Latency Performance Prescriptive Insights Beyond Monitoring Monitoring Creates Questions InfoSight Gives Answers Should I be concerned? Is this indicative of a problem? What s causing it? How do I fix it? Health severity indicators Correlated performance factors Clear recommendations When latency is more impactful

9 Correlates Data and Solves Problems Beyond Storage Root cause performance issues VM/Container/DB Pinpoint noisy neighbor VMs Compute Network Storage Repurpose underutilized hosts Avoid unnecessary upgrades

10 Latency (ms) Diagnoses Abnormal Latency with VMVision From Jan 24, 2017 To March 20, Latency Host 0.3 Network 0.13 Storage 0.24 Latency Spike Monday, March 6, Jan 30 Jan 4 Feb 7 Feb 11 Feb 15 Feb 19 Feb 22 Feb 26 Feb 1 Mar 4 Mar 7 Mar 10 Mar 14 Mar 16 Mar Host Network Storage Nimble VMVision

11 Latency (ms) Diagnoses Abnormal Latency with VMVision From Jan 24, 2017 To March 20, Latency Host 0.3 Network 0.13 Storage 0.24 Latency Spike Monday, March 6, Jan 30 Jan 4 Feb 7 Feb 11 Feb 15 Feb 19 Feb 22 Feb 26 Feb 1 Mar 4 Mar 7 Mar 10 Mar 14 Mar 16 Mar Host Network Storage Datastore: esxi289-1x I/O Total: 5,278,000 Avg Latency: 23.31msec VDI Sharepoint

12 Takes the Guess Work Out of Planning Predicts Upgrade Needs! Likely to exceed threshold: Sept 25 Predictive Analytics Answers: How has my data usage trended? When am I going to run out of capacity? Sizes Infrastructure Based on Applications Application Oracle Database What s the right SKU that I need for Oracle? What if I ran these apps...on the same array? Oracle data (GB) 1600 Apply CompressionArray Quantity Yes Percent reads AF AF Recommendation R Recommended R Recommended AF T Not Recommended

13 See Once, Prevent for All: Blacklist Updates Associated with Known Problems Customer A P v Customer B v Current OS: Release Update Path = Blacklisted Every array has a customized update path based on its unique configuration Every update available is safe and free of known problems

14 InfoSight Prevented 600 Systems from experiencing performance Issue! Issue: Simultaneous performance hit across all applications Impact Diagnostics Prevention 10x lower throughput higher latency, system unusable Illegal handling of SCSI response caused performance to drop. Nimble created a workaround until the vendor fixed the bug. 600 systems that would have experienced the issue were blacklisted

15 InfoSight points to faulty Server NIC! Issue: Strange latency behavior Impact Intermittent high Latency thru specific path Diagnostics End-to-End Correlational analysis shows high number of packet retransmits Prevention Replacing Server NIC Resolves issue

16 InfoSight Even Finds and Solves Security Vulnerabilities! Issue: Customers provisioning arrays on public IP addresses Impact Diagnostics Prevention Malicious cyber attack, DOS, Data theft (IP, Personal data, etc.) Automated ethical hacking techniques proactively identify at-risk systems daily 100 customers have been found with this vulnerability and are now protected
