1 1 Storage Performance Validation December 2014 Your Name Your title

2 2 Your Storage Challenges How to balance cost, risk, time to market?  Constant pressure to lower storage infrastructure costs  Need to quickly evaluate, deploy and de- risk new products & technologies  Need to rapidly roll out new infrastructure to support the business units Implement change without compromising performance and availability

3 3 Legacy Approaches to Your Challenges Over-provision storage infrastructure Blindly trust vendor specs & claims Validate with freeware load testing “Test in production & pray” “Our vendor will fix any problems” “Racks of servers/VMs & scripting”

4 4 Problems with Current Approaches Over- provisioning Trust vendor “best guess” Performance validation w/ freeware tools  Storage is ~40% of today’s IT infrastructure budget & growing  Wastes CAPEX  Vendors don’t have the data related to your workloads  Vendors can’t identify your performance limits; it’s your SLA  No scaling to production levels  No realistic scenarios  80% of time on setup; 20% on testing  Slows time to market

5 5 Who is Load DynamiX? Leader in storage performance validation Mission Provide actionable insight into storage infrastructure behavior to assure performance & optimize cost Product Suite  Software: Load DynamiX Enterprise  Hardware: LDX load generation appliance ;; Award Winning Technology

7 7 Technology Vendors IT Organizations Load DynamiX: The performance validation standard for both Vendors and IT organizations

8 8  Optimize Storage Investment Eliminate over/under-provisioning by aligning your workload requirements to deployment decisions  Mitigate Risk Identify issues before deployment by testing at extreme scale and worst-case conditions  Innovate with Confidence Adopt the latest storage technologies without the fear of unpredictable performance  Improve Lab & Engineering Efficiency Make better engineering decisions and reduce testing costs Benefits of Using Load DynamiX “If you can’t validate technology before it’s deployed into production, then you’re flying blind.” Julia Palmer, Performance Engineering Manager

9 9 Why IT Organizations Use Load DynamiX To Introduce Change with Confidence Technology Evaluation Product Evaluation Configuration Optimization Change Validation What technology is best for our business? Flash, Hybrids, NFSv4, FCoE, OpenStack, Ceph,... Which vendor and/or which product is best for each of our workloads / multiple workloads? Which mix of SSD vs. HDD is best for workloads? Benefits of tiering, caching, proper queue depth settings? Will patches, firmware and OS updates degrade performance, cause outages, or fix issues? Storage Validation Life Cycle Pre-Production Staging Validation Benchmark before going live and verify all connections, configurations and ports? More efficient testing enables full life cycle testing
