5. The Industry Challenge…...the “perfect storm”

6. I/O The Virtualization Challenge 1.The SAN has lacked any real I/O systems-level performance –Original FC spec was designed for 32 “storage channels” –Not designed as a “network” –Lacks self-health, diagnostics and transparency to the I/O FC Fabric There’s a “perfect storm” happening in data management today… Servers & Virtual Machines Storage Arrays SAN Cloud

7. Servers & Virtual Machines 1.The SAN has lacked any real I/O systems-level performance 2.Data growth at an unprecedented rate (average 30-60% CAGR) –A 200TB shop in ‘05 growing 50% is now 1PB & will be about 8 PB in 5 years –A net-new 7 PB of storage; how much will it cost, and where will it be deployed? There’s a “perfect storm” happening in data management today… SAN Cloud The Virtualization Challenge

8. 1.The SAN has been a “black box”, lacking any real I/O systems-level performance, so it’s heavily over-provisioned as a result 2.Data growth at an unprecedented rate (average 30-60% CAGR) 3.More “abstraction” being added –Further limits I/O visibility –Challenges performance –Slows deployment of cloud infrastructures There’s a “perfect storm” happening in data management today… Virtual Server Cloud SAN Cloud Storage Virtualization Cloud The Virtualization Challenge

9. Common Large-scale SAN Challenges Explaining/avoiding application outages & slowdowns Identifying SAN problems Identifying physical layer problems Reducing vendor finger- pointing Tracking SLAs & compliance Over-provisioning and consolidation Storage tiering Environmental costs (avoiding new data centers) Capacity planning Containing rising costs of storage/SAN w/ flat budget

10. Explaining/avoiding application outages & slowdowns Increasing server consolidation ratios Reducing vendor finger- pointing Tracking SLAs & compliance I/O subsystem troubleshooting Deploying Tier 1 mission critical applications Showing adherence to performance standards Isolating workload peaks that cause resource conflicts and bottlenecks Common Virtual Infrastructure Challenges

11. The primary virtual infrastructure challenge We have found greater than 90 percent of the VMware-related performance issues encountered by our customers are due to the storage tier. Scott Drummonds, Performance Specialist VMware

12. Virtual Server Market Share 2008-2012 ~ 55M vms~ 10M vms

13. Process and Tech Standard Phase “VM 1st” Policy Heavy-Use Phase Mission Critical More than just Servers Light-Use Phase “Virtualization-Lite” Pilot Phase Play TIME NUMBER OF VMs Are You Here? Phases of VMware Infrastructure Stuck due to: Lack of “know-how” Lack of Tier 1 app confidence Lack of client virtualization maturity Stuck due to: Lack of “know-how” Lack of Tier 1 app confidence Lack of client virtualization maturity Why Do Customers STOP Here?? VISIBILITY….of I/O Why Do Customers STOP Here?? VISIBILITY….of I/O

14. Identify / fix physical & virtual infrastructure problems before they occur Ensure no loss of revenue/ productivity Reduce Risk Optimize IT asset utilization and personnel Reduce Costs Tier 1 apps meet performance SLAs I mprove Performance What is needed… C reate “Predictability”

15. ProbeV Identifies low overall SAN utilization via real-time dashboard Identifies individual port utilization Enables verification of historical utilization trends to verify loads over time Enables intelligent load balancing to avoid expensive purchases Avoiding Over-provisioning of Links 90% of ports used less than 10%

16. Improving SAN Utilization and Mitigating Risk SAN utilization < 2% Some links hitting 100% Traffic on ISL’s causing contention SFP low-light levels & flopping HBA’s causing CRC issues Categorization Summary Count% of Links Balanced122869% Passive855% Active855% Imbalanced22813% Single (not redundant)1438% ProbeV Software Audit

17. Record and play back metric recordings of intermittent problems before they build up and disrupt the SAN Faster Troubleshooting & Root Cause Analysis ProbeFCX Continuously monitors and filters in real-time Calculates statistics based on measuring all fibre channel frame traffic Automatically notifies staff based on exceeded policy thresholds Real-time root-cause analysis

18. Avoiding Performance Problems ProbeFCX Identifies potential application slow-down causes Recommends corrective action before the slowdown Enables fixes before application owner is aware of the problem Provides visibility into Queue depths, CRC errors, physical link errors, protocol errors, code violations, etc

19. Optimizing Application Performance ProbeFCX Measures all network statistics Proactively alerts administrator based on policies Enables real-time tuning for maximum performance

20. Expanding VMware to Mission-critical Applications ProbeVM Monitors CPU, memory & SAN utilization and I/O response time Identifies performance bottlenecks & recommends vMotion transfers Enables “what if” load balancing simulations Proves consolidation ratios can be improved w/out performance degradation OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP OS APP
