1 Integrating 16Gb Fibre Channel and 10GbE Technologies with Current Infrastructure

2 Agenda Benefits of Converging Fibre Channel and Ethernet Why Separate Networks, Separate Technologies Enabling Convergence Lossless Ethernet Convergence one-wire network Implementing Convergence Fabric Freedom (16 Gb FC and 10Gb Ethernet) Key takeaways Q & A 2

3 Benefits to customers who implement converged networks? 70% of IT budgets are being consumed by operating costs Lower CAPEX and OPEX: 3 The number of adapters, switch ports and cables is greatly reduced Lower power, space and cooling requirements Standardize on one underlying networking technology Lower management overhead and improve operations efficiency Reduce hardware spares inventory requirements

4 Benefits to customers who implement converged networks? No need to rip and replace Protect investments in existing infrastructure: Integrates with existing LAN and SAN infrastructure, tools and training Maintains existing provisioning and process tasks for SAN eco-system Retain enterprise-proven Fibre Channel drivers 4

5 Benefits to customers who implement converged networks? Prepare for the Cloud Improve IT agility and service delivery capabilities: 5 Select appropriate protocol based upon application/business requirements Leverage virtualization-based high availability solutions Provides the underlying foundation for service-oriented, Utility-based computing

6 Traditional Data Centers: Why separate networks? Different application requirements => Different operating environments => Different technologies 10GbE LAN IP/Ethernet 8/16Gb FC SAN Fibre Channel Data Network Storage Network 6

7 Traditional Data Centers: Data Network Operating Environment 10GbE LAN IP/Ethernet Data Network operating environment (TCP/IP): Legacy: Early Internet low speed, errors common , File transfers, Web Browsing less delay sensitive Congestion/Packet Loss/Retransmission normal operation Handled by TCP/IP no facility in Ethernet, not needed 7

8 Traditional Data Centers: Storage Network Operating Environment 8/16Gb FC SAN Fibre Channel Storage Network operating environment (Fibre Channel): Legacy: SCSI - host to peripheral (disk) locally attached Lost packets meant something broken BSOD level problem SCSI assumes no packet loss recovery is an exception (failure) FC network provides access control to avoid congestion, loss 8

9 Evolution of the Data Center: Lossless Ethernet Business case for Lossless Ethernet: IP/Ethernet is everywhere deployment is ubiquitous Internet Protocol is the foundation for the Internet and the World Wide Web LAN, WAN, VoIP, IP Video, Mobile The convergence of Voice and Data has already happened Economic advantages Drives convergence to one infrastructure 9

10 Evolution of the Data Center: Lossless Ethernet operation Protect Avoid congestion, loss of lossless traffic Identify Drop non-lossless traffic When congestion in the network does happen, drop the other traffic, not the lossless service traffic 4 1 Determine which traffic needs lossless service Eg. FCoE and iscsi storage Control Reserve 3 2 Limit the amount of lossless traffic on the network Don t overrun the reserved bandwidth Avoids congestion and lost packets in 'lossless' priority traffic Specify bandwidth for lossless service Ensure that there is always some bandwidth dedicated to lossless service traffic

11 Evolution of the Data Center: Data Center Bridging Manage the flow of traffic on the network Avoid congestion and the risk of packet loss DCB Enhanced Ethernet implements (Data Center Bridging IEEE working group): Enhanced Transmission Selection (ETS: 802.1Qaz) traffic classification Priority-based Flow Control (PFC: 802.1Qbb) access control per traffic class Congestion Notification (CN: 802.1Qau) congestion monitoring and management Data Center Bridging exchange (DCBX: 802.1Qaz) DCB capabilities management 11

FCoE edge to 8Gb FC SAN II. Add 16Gb FC SAN - Trigger: PCI-e 3.0 servers (Romley) III. Add FCoE ToR (Eth and iscsi connections) a) Converging to one-wire network b) Retire 8Gb SAN FCoE 10GbE FCoE Storage 1Gb/10GbE LAN IP/Ethernet Data Network 10Gb FCoE 16Gb FC iscsi NICs CNAs HBAs Existing infrastructure w/ separate Data and Storage Networks (NICs and HBAs) E- port or TR Storage Network 16 Gb FC 8Gb FC SAN Fibre Channel 10GbE iscsi 10GbE NAS Add CNAs and Converged Switching to infrastructure Add Inter Switch Link to existing 8Gb FC SAN either Full Fabric or Transparent Routing connection When ready, add 16Gb FC storage to Converged Network When ready, add FCoE TOR switch capability to Converged Network FC Storage iscsi Storage NAS Storage 12

13 Conclusion Key Takeaways Network Convergence, along with Virtualization of the server, network and storage infrastructure are driving the next gen data center toward a service-based, cloud-enabled computing model Network Convergence Lowers CAPEX and OPEX Transitions can be done in phases FlexPort-based Fabric Freedom is a key enabler protect investments and future proof the infrastructure Improves IT agility and service delivery capabilities I/O efficiency is a key element Exploding I/O bandwidth requirements, expect 100 X increase in 72 months Protect CPU utilization with protocol offloads Lower capital and operating expenditures Data center computing is in the process of moving to the cloud and network convergence using enhanced Ethernet is an enabling technology 13
