Agenda
Virtualized Data Center Trends
FCoE Overview
FCoE Value Proposition
FCoE Deployment
VM Mobility with FCoE
Cost saving with FCoE – An example

Drivers for Virtualization
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

Virtualized Data Center Trends
Multi-Core CPUs allow bigger and multiple workloads, increase server
consolidation
Virtual Machine IO Performance near Physical Machine requiring more bandwidth
per server
(IO Virtualization, Hardware assists, Offloads)
Reduced Hardware Components reduces Power and Cooling cost
(Nearly 60% of data center cost comes from Power and Cooling)
Simplified Management and Dynamic Provisioning

Accelerating Technology Adoption
Server consolidation and blade server deployments promote
Higher bandwidth through pass-through or blade switch
FCoE convergence technology adoption
Need for higher bandwidth accelerating introduction of standards

FCoE Management Compatibility
Deploy common SAN practices such as FC zoning, LUN masking, etc.
Transparent Layer 2 FCoE to FC address mapping
Build failover solutions using multi-pathing software
Same driver interface as FC
Troubleshoot LAN/SAN issues
Unique “Ethertype” for FCoE data traffic

Reuse proven SAN & LAN management practices
Reuse familiar SAN & LAN management tools
Reuse in-house SAN & LAN admin expertise

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
PHASE 2: Converged Network consolidates network resources while coexisting with current networks
PHASE 3: Simplified data center with Server and Network Consolidation reduces IT cost
NO NEED for infrastructure overhaul; deploy in phases
NO NEED for rip and replace; use existing LAN & SAN
NO NEED for two convergence technologies; one fits ALL

FCoE Deployment with VLAN
Simplify deployment with independent VLANs:
Configure FCoE on a dedicated VLAN
Configure TCP/IP networking on one or more other VLANs
Zoning for FCoE traffic can be configured within the FCoE VLAN
FC Zoning maps to Ethernet ACLs

SAN and LAN bandwidth allocation using ETS
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

ETS Overview
Traffic requiring similar behavior classified into Priority Groups
Each Priority Group allocated Bandwidth as a % of available link bandwidth
Up to 8 traffic priorities allowed within a Priority Group
Defined by 802.1Q Priority field
ETS allows seamless coexistence of SAN and LAN traffic on the Converged Enhanced Ethernet

FCoE Fabric
FCoE supports N-port ID Virtualization similar to FC
FC zoning configuration migrated with NPIV
All other Virtual Port properties migrated to new host along with NPIV
