3 Who is SIOS? Founded in 1999 Formerly SteelEye Technology Headquarters in San Mateo, CA Offices across the US, UK and Japan Recognized Experts in Application Availability Thought Leaders in Machine Learning based IT Analytics Partners are Industry Leaders 2016 SIOS Technology Corp.

4 Moving SQL Server to Virtual Environments Save Money o Server consolidation o Improved resource utilization o Improved staff resource utilization (easier management) Improve Flexibility o Add, move, remove VMs quickly, easily as needed Continue to Meet Stringent Service Levels o Performance, Efficiency, Reliability, and Capacity Utilization 2016 SIOS Technology Corp. All rights reserved. 4

5 Challenges Faced by IT Meeting Strict Service Levels for Business Critical Applications Complex infrastructures with interdependent objects Host CPU and memory often maximized Continuously moving VMs from host to host VM sprawl VDI and more Tier 1 apps virtualized Significant I/O contention Latency sensitive applications suffer Unhappy, unproductive end users of business critical applications 2016 SIOS Technology Corp. All rights reserved. 5

6 Challenges faced by IT Traditional Tools Fall Short Limited Visibility into Operating Status Across the Infrastructure Tools designed for standalone hosts or individual infrastructure silos (Network, Application, CPU, Host) Threshold based Tools are Limited Measure one quality in one object (CPU utilization) cannot reflect behavior of interrelated objects Create Alert Storms that Inundate Administrators Root Cause of Performance Issues is Unclear 2016 SIOS Technology Corp. All rights reserved. 6

7 SQL Administrators vs Infrastructure Administrators Fingerpointing Among Domain Experts What is the Root Cause of the Performance Issue? Who has responsibility for fixing it? How do you resolve the issue? Communication and Collaboration: Application Administrator / DBA Network Administrator Infrastructure Administrator 2016 SIOS Technology Corp. All rights reserved. 7

8 What is Needed? Single View Across the Infrastructure Performance and Other Issues Identified, Prioritized Root Cause of Issues Identified Specific Recommendations for Resolving Issues Provided Ease of Use Resulting in: Improved Communication Across Job Functions Faster, More Accurate Issue Resolution 2016 SIOS Technology Corp.

9 SIOS iq Next Generation IT Operations Analytics for SQL on VMware

10 Your First Stop for Answers to VMware Infrastructure Questions Machine Learning Based IT Operations Analytics Solution What is the status of my operations across the infrastructure? Will I meet my SQL Server SLAs? Is the root cause of my performance issue in the infrastructure or in the application? How do I resolve performance issues? Did I solve my recent performance problem or just move it? Are we wasting virtual resources? How much capacity will we need next quarter? Next year? How should I configure host based caching, all flash arrays or hybrid storage for maximum benefit? 2016 SIOS Technology Corp. All rights reserved. 10

11 What are Next Generation IT Analytics? Legacy Tools Manual Configuration: Requires configuration & continual adjustment Threshold based Rules: Limited insight into operations causing alert storms Reactive: Reports current events that IT must react to Provides Data: IT left to analyze multiple sources SIOS iq Machine Learning Analytics Self Configuring: Requires minimal configuration self adjusting Self Learning: Automatically learns delivering only meaningful issues Proactive, Preventative: Predictive analytics identifies impending issues Provides Intelligence: Deep analytical understanding with recommendations 2016 SIOS Technology Corp. All rights reserved. 11

12 Topological Behavior Analysis & Machine Learning Automatically learns relationships and behavior patterns to uncover hidden interactions that underlie the root cause of issues Multi dimensional behavior Analysis Of Related Measurements (Latency and IOPS for example) Transforms Data into a Topology Map Measures and analyzes interrelated objects Learns behavior of interrelated objects. Identifies anomalies Derives root cause and recommendations 2016 SIOS Technology Corp. All rights reserved. 12

13 Integrated View Across Infrastructure and Application 2016 SIOS Technology Corp. All rights reserved. 13

14 New Integration: SIOS iq & SQL Sentry Performance Advisor Machine Learning Analytics AND MS SQL Server Platform Deep Insight SQL Sentry Performance Advisor comprehensive performance monitoring and event management platform SIOS iq machine learning analytics solution learns infrastructure behaviors SIOS Technology Corp.

22 Biggest Challenge in High Availability Scaling performance as workload increases Increasing IO throughput Increasing IOPS Making it go faster 2016 SIOS Technology Corp. All rights reserved. 22

23 Traditional Options More spindles Faster spindles More spindles Faster spindles More spindles Faster spindles Complains that it isn t getting any faster 2016 SIOS Technology Corp. All rights reserved. 23

24 More Isn t Always Better SAN storage isn t cheap Array s can only hold so many disks Adding disks has other costs Power Cooling Rack space Networks can only pass data so quickly Cost benefit ratio may not be there 2016 SIOS Technology Corp. All rights reserved. 24

25 How To Go Faster? PCI based flash drive Not like USB drives, faster Directly attached to the PCI bus PCI express 3 bus speeds are up to 256 Gbit/s (31.5 Gbytes/s) Bottleneck becomes how fast SQL server can process the IO 2016 SIOS Technology Corp. All rights reserved. 25

26 Flash Isn t Perfect PCI based flash drives don t have a good native high availability option This is due to the fact that they are locally installed Needs to be supported by Microsoft Needs to be Cluster aware 2016 SIOS Technology Corp. All rights reserved. 26
