2 Agenda Trends in irtualized Data Centers FCoE CNA Compatibility with FC IO irtualization with FCoE CNAs FCoE Phased Deployment Software FCoE v/s FCoE CNA Deployment obility and QoS with FCoE CNA Brief Case Study of FCoE Deployment February

3 Drivers for irtualization IDC survey suggests virtualization driven by 4 key factors Server consolidation Business continuity Test and development Resource pooling and sharing leading to dynamic provisioning Industry experiencing rapid growth of virtualization WW Software Revenue Forecast February Source: IDC irtualization Tracker Survey, 2008

4 irtualized Data Center Trends ulti-core CPUs allow bigger and multiple workloads, increase server consolidation irtual achine IO Performance near Physical achine requiring more bandwidth per server (IO irtualization, Hardware assists, Offloads) Reduced Hardware Components reduces Power and Cooling cost (Nearly 60% of data center cost comes from Power and Cooling) Simplified anagement and Dynamic Provisioning February

5 FCoE Overview It is just Fibre Channel encapsulated in Ethernet FC frames are not modified enroute FCoE Goal FCoE Packet: Enable Server I/O Consolidation and FC Frame: FC Header Network Convergence Payload S O F Ethernet Header FCoE Header FC Header Payload CRC E O F February

6 FCoE CNA Software Compatibility FC and NIC Driver odel Operating System FCoE and NIC Driver odel Operating System Network Stack NIC Driver Storage Stack Network Stack Reliability from field proven driver stack 100% FC Driver application transparency NIC Driver Investment protection and smooth transition Storage Stack FC/FCoE FCoE Driver February

7 Operating System view of FCoE CNA Storage Ethernet February

8 FCoE CNA anagement Compatibility Deploy common SAN practices such as FC zoning, LUN masking, etc. Transparent Layer 2 FCoE to FC address mapping Reuse proven SAN & LAN management practices Reuse familiar SAN & LAN management tools Build failover Reuse solutions in-house SAN & using LAN admin multi-pathing expertise software Same driver interface as FC Troubleshoot LAN/SAN issues Unique AC address or Ethertype for FCoE data traffic February

10 FCoE Phased Deployment TODAY: Dual adapters and networks for LAN and SAN PHASE 1: CNA reduces power, enables efficient use of real estate in blades NO NEED for infrastructure overhaul; deploy in phases NO NEED for rip and replace; use existing PHASE LAN 2: Converged & SAN Network NO NEED for two convergence technologies; consolidates one network fits ALL resources while coexisting with current networks PHASE 3: Simplified data center with Server and Network Consolidation reduces IT cost February

12 Why not Software FCoE? Performance disclaimer from FCoE Initiator Functional Specification * : This is a software FCoE solution, there are code paths which are CPU intensive (e.g. FC-CRC calculation). Depending on the CPU power, when I/O traffic through the FCoE ports is heavy, CPU utilization could go very high. * - Source: Solaris Open Storage FCoE Initiator Functional Specification, v1.00, Jul 30, 2008 February

13 QoS Configuration with FCoE CNA 10Gb CEE FCoE SAN LAN SAN and LAN bandwidth allocation using ETS vwwn1/npi1 vwwn2/npi2 Enhanced Transmission Selection (ETS) protocol allows bandwidth percentage allocation across FCoE SAN and Networking traffic Further, FC level QoS can be configured for the bandwidth allocated at FC level February

17 Cost per server Cost Savings from FCoE CNA deployment Component FC and Ethernet FCoE Cable $300 $200 FC HBA (2-port) $1200-1GbE NIC (2-port) $800-10GbE FCoE CNA (2-port) - $1800 FC switch $2400-1GbE switch $ FCoE switch - $4000 Total $7500 $6000 Total Cost (26 servers) $ $ % February

18 What to look for when you buy FCoE CNA? Full FCoE protocol offload Full 10GbEE NIC functionality with stateless offloads Certified across Operating Systems and Platforms Single ASIC solution with low power dissipation Leveraged from years of FC expertise and field proven drivers and management apps End-to-end ecosystem support February
