2. Emulex LightPulse®LPe16000B-series Gen 5 Fibre Channel HBAs The Best HBA for Virtualization, Cloud, Databases, and Big I/O Applications

3. What is Gen 5 Fibre Channel? • Speed-based naming changed to generational-based naming • Includes new protocol services & features, not just bandwidth improvement • Emulex Gen 5 includes adapters running multiple speeds • 16GFC/8GFC/4GFC • Maintains backward compatibility to previous FC generations 1Gb Fibre Channel 2Gb Fibre Channel 4Gb Fibre Channel 8Gb Fibre Channel Gen 5 Fibre Channel Gen 6 Fibre Channel 16Gb 32Gb Gen 1 Gen 2 Gen 3 Gen 4 • Advanced features • Multi-speed • 16GFC/8GFC/4GFC Gen 5 = Advanced Features Plus Multi-protocolAdapters Running Multiple Speeds

4. Gen 5 Addresses Today’s Data Center Challenges Virtualization & Cloud Flash/Cache Databases • Maximize VM density • Enable mission-critical and big I/O application SLAs • Eliminate I/O bottlenecks • Avoid I/O bottlenecks for expensive app acceleration investments • Fabric optimization for new distributed flash use cases like vMotion • Enable data growth and peak workloads • Fastest response time drives competitiveness • Optimize for virtualization and flash cache FC is the Most Trusted Fabric for the Enterprise SAN

5. IT Mandate: From Storage Capacity/Utilization to Application Performance $/GB $/IOPS Focused on Storage Capacity Virtualization/Cloud/Web Need Application Performance &Quality of Service Disk & Traditional Fabric Flash Tiers & Optimized Fabric • Traditional disk arrays and fabrics have helped solve storage capacity problem • Near-zero space snapshots • Automatic de-duplication of redundant data • High-performance dual-parity RAID systems • Data cloning techniques • Application performance/SLAs are now the focus • Flash tiers + new Intel servers means fabric I/O is now the bottleneck • Shared/distributed storage use cases like vMotion, HA/DR, & clustered apps require fabric optimization • Requires faster data access- operational latency and IOPS for app response time • Mixed virtualization/cloud workloads and mission critical apps demand QoS, latency,data integrity

6. Emulex Gen 5 LPe16000-Series Accelerates Application Performance vs. LPe12000-series 8GFC Up to Up to 41% 33% Faster workload completion for Microsoft SQLServer More Transactions per Second for Microsoft SQLServer (100-400 users) Database Applications Data Warehousing Workload Virtualization / Cloud Exchange Workload Up to Up to 3x 75% Better throughput for VMware ESXi IOPS for Exchange-like workload Up to

7. To Get 25%-45% Better Application Performance You Could… Spend hundreds ofthousands of dollars Spend a few hundred dollars/server on Gen 5 HBAs OR • More servers • More software licenses • More power • Increased IT management costs • Simple plug and play performance upgrade • Compatible with 4GFC/8GFC infrastructure • No additional management costs/ complexity Gen 5 HBAs Deliver The BiggestPerformance Improvement Per Dollar

8. Emulex Gen 5 Simplicity 50% 4x Reduction in the number of ports & cabling requiredin a server Better IOPS performanceper watt Consolidation Power Efficiency Superior SAN Diagnostics Streamlined Management Less time to install and manage vs. other HBAs; with no re-boot upgrades 50% 100% Confidence with comprehensive troubleshooting and SAN optimization

10. Ethernet und Latenzen

11. Next Generation networking with EmulexSkyhawk Software Defined Convergence Platform

12. High Performance Networking Skyhawk RoCE RoCE is IB Over Existing Network Infrastructure What is Remote Direct Memory Management (RDMA)? • Ability to remotely manage memory enabling server to server data movement directly between application memory without any CPU involvement • A mechanism to provide this efficient data transfer with very low latencies on Ethernet • Basically IB Over Ethernet (with PFC, etc.) • Classic Ethernet is a Best Effort Protocol What is RDMA over Converged Ethernet (RoCE)? • Delivers low latency for performance-critical and transaction intensive applications • Better OPEX vs. Infiniband infrastructure which is requires a unique fabric which is difficult to deploy and manage Benefits of Skyhawk-R with RoCE
