2. Agenda Introduction Virtualization at Presenter firms Virtualization Basics Planning and Design Best Practices Barriers to Virtualization Other Virtualization Opportunities (Desktops/Applications) Lessons Learned The Future of Virtualization A word from the event Sponsor Q&A

3. Virtualization at Presenter firms Bracewell & Giuliani LLP Data Centers (Primary and Secondary) are running ESX 3.0.3 with Virtual Center and VMotion configuration. Primary Data Center - HP Proliant DL585s (Quad Dual Core AMD processors with 32GB of RAM). FC SAN HP EVA 6000 4GB Fabric. Cisco GB Switching environment Catalyst 4500 series. Secondary Data Center - HP Proliant BL25s (Dual Dual Core AMD processors with 12GB of RAM). FC SAN HP EVA 6000 2GB Fabric. Cisco GB Switching environment Catalyst 4500 series. 25:1 Ratio – DC's, File/Print, DM, Elite, Citrix, IIS/SharePoint, and others. Satellite offices are running ESX 3.0.3. HP Proliant DL385 G2 Dual Dual-Core processors with 8GB of RAM. FC and iSCSI connected SAN HP MSA 1500 (cs and i) 2GB Fabric. 4:1 Ratio – DC, File/Print, DM Cache, Security (IP Cameras)

4. Virtualization at Presenter firms Vinson & Elkins LLP Centralized Two node Peer Data site utilizing a Flat Network Blade Servers with dual Quad core Intel Processors and 32 GB RAM running Windows Server 2008 with Hyper-V Storage provided by a fiber channel connected Dell/EMC SAN VM to Host ratio determined by monitored resource utilization (Planned between 1:1 up to 15:1 Host to guests) Staged deployment Plan Standard application servers (In Production) Clustering / Replication Implementation (Testing / POC) FC attached and Mission Critical systems (Planned)

5. Virtualization at Presenter firms Baker Botts L.L.P. Data Centers (primary and backup) is running ESX 3.5 with Virtual Center including DRS, HA & Vmotion. Data Center Virtualization on Blades with SAN connected (FC) storage for Guests. Each Server has two Dual Core processors and 36 GB RAM. ESX runs on local Disk but all Guests on SAN What is virtualized? - Original goal was everything but SQL/Exchange. (Now we have some SQL/Exchange Virtualized) Virtualization Ratios: 16 Physical servers hosting 150+ servers. (Note: Includes "headroom" for failover) Separate DMZ VMWare farm Local & International Offices operating on 2 node MS Virtual Server Cluster

6. Virtualization Basics What is Virtualization? Why go virtual? Hardware benefits. Maintenance, Patching and capacity management. Disaster Recovery / High Availability. Why Not?

7. Planning and Design Best Practices Ask for vendor resources – Calculators, Planners and roadmaps. Monitoring / Management – Worth the effort before you migrate. Find the Hardware sweet spot. Start small, Get comfortable. P2V – Use the tools, they really work…..but have a backup. Cross department support. Networks, storage and applications Test, Test, Test. Virtual Server Policy.

8. Barriers to Virtualization Myths and Reality Need Myth – Under-utilization and space constraints are the only reasons for virtualization. Reality – Has become a best practice for hardware/software life cycle management, high availability, and disaster recovery. Technology Maturity Myth - Not a mature enough technology to deploy in a production environment. Reality – Has been around since the 60's (think mainframe) and on the x86 platform for nearly a decade. ESX, XenServer, and Hyper-V are each on at least the second generation of their respective platforms. Vendor Support Myth - Few vendors will support their application on a virtual server. Reality – More vendors supporting applications on hypervisors. Many are packaging their application as a virtual appliance. Microsoft's virtualization support policy has increased adoption (KB897615).

9. Barriers to Virtualization Myths and Reality I/O Intensive Applications Myth –SQL and Exchange should not be virtualized. Reality – Mission Critical applications are prime candidates for virtualization. Review system requirements and performance first. Some cases merit a 1:1 ratio. In-house Skill set Myth – Developing engineers and administrators takes too long and costs too much. Reality – Virtualization is available on common OS, storage, and networking platforms. Training, certification tracks, publications, and technical sites are readily available for the major vendors. Costs Myth – The initial cost will be too much. Reality – Most hypervisors now offer a free platform. Microsoft licensing provides reduction in cost using Enterprise or Data Center. Hardware can be re-used.

10. Other Virtualization Opportunities (Desktops/Applications) Desktop Virtualization Why – Reduce cost of management (deployment, patch management, security), extend hardware lifecycle, provide seamless user interface, mobility How – Session Based Computing (SBC), OS Streaming, True Client Virtualization, PC Blade Barriers – Graphics, local devices, initial investment, in-house skill set Application Virtualization Why – Reduce cost of management (deployment, patch management, security), application isolation, license management How – SBC, Application Streaming, Portable Applications, Barriers – Graphics, application packaging, OS integrated applications, in- house skill set

11. Lessons Learned Non Technical Understand your RPO's/RTO's and SLA's (Availability and DR Expectations) Vendor and Stakeholder (Internal) support Technical I/O Constraints Backup and restore challenges Storage performance to ensure IOPS for app needs (SQL, Exchange, etc.) More Hardware Level Virtualization - even if 1 to 1. VMDK's vs. RDM (Raw Disk) Too much Engineering is a good thing - and include Networking, Storage, OS Experts et al. Learn Command line utilities Processor choices are important Don't forget the "headroom" Security challenges

12. The Future of Virtualization Hardware Level Virtualization cost is almost $0 Cost is in functionality/management components Move towards higher density CPU servers Convergence of Network and Storage Fabric "ParaVirtualization" More Virtual Appliances Virtualization is well beyond "hardware virtualization" Desktop Virtualization Software Virtualization Virtualization/Cloud Computing/IaaS Beware the term "Virtual"
