Benefits to customers who<br />
implement converged networks?<br />
70% of IT budgets are being consumed by operating costs<br />
Lower CAPEX <strong>and</strong> OPEX:<br />
3<br />
• The number of adapters, switch ports <strong>and</strong> cables is greatly reduced<br />
• Lower power, space <strong>and</strong> cooling requirements<br />
• St<strong>and</strong>ardize on one underlying networking technology<br />
• Lower management overhead <strong>and</strong> improve operations efficiency<br />
• Reduce hardware spares inventory requirements
Benefits to customers who<br />
implement converged networks?<br />
No need to “rip <strong>and</strong> replace”<br />
Protect investments in existing infrastructure:<br />
• Integrates <strong>with</strong> existing LAN <strong>and</strong> SAN infrastructure, tools <strong>and</strong> training<br />
• Maintains existing provisioning <strong>and</strong> process tasks for SAN eco-system<br />
• Retain enterprise-proven <strong>Fibre</strong> <strong>Channel</strong> drivers<br />

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

Traditional Data Centers:<br />
Data Network Operating Environment<br />
<strong>10GbE</strong><br />
LAN<br />
IP/Ethernet<br />
Data Network operating environment (TCP/IP):<br />
• Legacy: Early Internet – low speed, errors common<br />
• Email, File transfers, Web Browsing – less delay sensitive<br />
• Congestion/Packet Loss/Retransmission – normal operation<br />
• H<strong>and</strong>led by TCP/IP – no facility in Ethernet, not needed<br />

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

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

Evolution of the Data Center:<br />
Lossless Ethernet operation<br />
Protect<br />
Avoid congestion, loss of ‘lossless’ traffic<br />
Identify<br />
Drop non-lossless traffic<br />
• When congestion in the network<br />
does happen, drop the other<br />
traffic, not the lossless service<br />
traffic<br />
4<br />
1<br />
Determine which traffic needs<br />
lossless service<br />
• Eg. FCoE <strong>and</strong> iSCSI storage<br />
Control<br />
Reserve<br />
3<br />
2<br />
Limit the amount of ‘lossless’<br />
traffic on the network<br />
• Don’t overrun the reserved b<strong>and</strong>width<br />
• Avoids congestion <strong>and</strong> lost packets in<br />
'lossless' priority traffic<br />
Specify b<strong>and</strong>width for lossless<br />
service<br />
• Ensure that there is always some<br />
b<strong>and</strong>width dedicated to lossless service<br />
traffic
Evolution of the Data Center:<br />
Data Center Bridging<br />
Manage the flow of traffic on the network<br />
Avoid congestion <strong>and</strong> the risk of packet loss<br />
DCB<br />
Enhanced Ethernet implements (Data Center Bridging – IEEE 802.1 working group):<br />
• Enhanced Transmission Selection (ETS: 802.1Qaz) – traffic classification<br />
• Priority-based Flow Control (PFC: 802.1Qbb) – access control per traffic class<br />
• Congestion Notification (CN: 802.1Qau) – congestion monitoring <strong>and</strong> management<br />
• Data Center Bridging eXchange (DCBX: 802.1Qaz) – DCB capabilities management<br />

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