Virtual Servers Breakthrough solutions to data center issues: Consolidation, cost reduction Rapid provisioning Continuity of service Massive market success: All FORTUNE 100 have virtual servers in production or evaluation 7,000 users at VMworld November 2006 Virtualzed servers: 6% of all servers now, 18-20% in 2008, 40% in 2010 (IDC) VMware dominates current shipments. Microsoft investing heavily (Longhorn, Novell announcement, etc). Strong synergy with Fibre Channel Continuity of service and consolidation require shared networked storage Over 80% of VMware servers are FC connected About 2/3 of VMware FC connections through Emulex

LightPulse Virtual HBA Technology What is Virtual HBA technology? Enables an HBA to present multiple ports (WWPN) to the fabric Implements the ANSI T11 N-Port ID Virtualization standard. What are Virtual HBAs useful for? Manage virtual machine connectivity like physical machine connectivity: VM-level fabric zoning, LUN masking/mapping VM-level fabric guaranteed bandwidth (QOS), diagnostics, statistics, and chargeback Move/recover SAN–attached configurations seamlessly HBA Fabric switch Arrays And LUNs Arrays And LUNs Virtual port

Emulex Leadership on virtual HBAs Thought leadership: Pioneered the concept with IBM ( ) Detailed usage with leading end users ( ) Educated industry analysts, press, major vendors Public demonstrations: Emulex-VMware demonstration October 2005 Additional demos with Intel dual-core technology, Xen Open Source, etc. No other vendor has demonstrated virtual ports on VMware as yet Product availability: Emulex 4 gigabit HBAs include LightPulse Virtual HBA technology now Linux driver for open community use: September 2006 Windows driver, general availability: November 2006 VMware driver, general availability: first half 2007

VMPilot: virtual connectivity made easy A solution for Microsoft Virtual Server Simple Wizard creates SAN-connected virtual machines with Virtual HBA Ports and unique LUNs Single command to migrate VMs with their Vport No more storage/fabric reconfiguration Availability: First public demonstration at Microsoft Tech-Ed (November 2006) General release planned for Q1, 2007 Utilizes standard driver for Windows 2003, 4GB adapters and firmware Deployment and management solutions for VMware, Linux, Xen, Solaris are being built jointly by Emulex and an ecosystem of value- add partners Virtual HBAs ABC Virtual Server SAN Virtual HBAs Server 1 out of resources !
