Virtual Machine GranularityIntroducing VN‐Link

Problems:

VN‐Link:• Extends network to the VM • Consistent services • Coordinated, coherent management

VMotion

• VMotion may move VMs across physical ports—policy must follow 

• Impossible to view or apply policy to locally switched traffic

• Cannot correlate traffic on physical links—from multiple VMs

• Mapping of FC Frames over Ethernet

• Enables FC to Run on a Lossless Ethernet Network

• Fewer Cables• Both block I/O & Ethernet 

traffic co‐exist on same cable

• Fewer adapters needed

• Overall less power

• Interoperates with existing SAN’s• Management SAN’s 

remains constant

• No Gateway

Cisco Unified Computing System

Unified Fabric

• Wire once, low latency FC and Ethernet

• Virtualization aware • Dramatic reduction in adapters, switches, pass thru modules

Industry Standard Servers• Blade Form Factor• Intel Xeon Processor 5500

series.• More than double the

memory capacity of competing systems

Virtualized Services

• Fine-grained control, portability, and visibility of network, compute, and storage attributes• Increased Processor Efficiency with Hypervisor Bypass

Up to 30% fewer components, switches, cabling, and management modules to purchase, manage, power, and cool

Up to 30% lower memory and SW licensing costs via Cisco Extended Memory Technology

Up to 10% better processor performance via Cisco Hypervisor Bypass Technology

Automated Provisioning

• Embedded single point of management and provisioning• Visibility and control across technology silos• Ongoing management and compliance

Up to 90% greater administrator efficiency, with faster changes and fewer incidents
