Datacenter Becomes an Efficient and Resilient Private Cloud

Shared pools of resources Self-optimizing Fault tolerant

• Self-protecting• Automated • Desktop or Server Workloads


Cloud Computing is the Logical Extension of Virtualization

Virtualized DatacentersSecure Private Cloud

Cost savings through server consolidation Even more cost savings

vSphere availability features as one primary way to lure applications into the virtualized environment.

vSphere private clouds and vClouds promise enterprise-grade QoS that makes it safe for those apps to be run in them

Rapid VM provisioning has given IT departments a way to be more agile and more responsive to business needs.

Clouds give you VMs as fast as you can type in your credit card number (within reason).

Virtualization increases end user choice and flexibility by abstracting away the underlying hardware, OS etc.

Cloud federation promises a way to extend that choice to infrastructure that sits outside your own premises and on someone else’s balance sheet, while still allowing you to maintain the same security posture


Fibre Channel over EthernetTechnology Components

Fibre Channel Over Ethernet (FCoE)

Ethernet is a “best-effort” network– Packets may be dropped– Packets may be delivered out of order– Transmission Control Protocol (TCP) used

to reassemble packets in correct order

Data Center Bridging (aka “lossless Ethernet”)– The “bridge to somewhere” – pause-based

link between nodes– Provides reliability and low latency required

for FCoE support


Feature Benefit Standards

Priority-based Flow Control (PFC)

Enables lossless Ethernet – manages I/O between initiator and target on a multi-

protocol Ethernet linkIEEE 802.1Qbb

Quality of Service (QoS) Supports 8 priorities for network traffic IEEE 802.1p

Enhanced Transmission Selection (ETS)

Allocate bandwidth to IP, iSCSI and FCoE traffic – managed with OneCommand

ManagerIEEE 802.1Qaz

Data Center Bridging Capability Exchange

(DCBX)

Extends DCB network by exchanging Ethernet parameters between DCB

switches IEEE 802.1ab

IEEE Data Center Bridging Standards


Fibre Channel over Ethernet• Relies on DCB to provide lossless transmissions with

low latency• Encapsulates complete Fibre Channel frames within

an Ethernet frame

Virtualization Smoothes Migration

• FCoE can be “bolt-on”, or you can upgrade non-disruptively with vMotion

• vMotion shifts resources allowing servers to maintain connectivity

• Reduces downtime risk

Beyond the Access Layer

• Creating flexibility and agility throughout

• Can you borrow Ethernet bandwidth to give to Fibre Channel?

• With FCoE, you can!

In Summary

• Server Virtualization increases demands for SAN & LAN

• Opportunities to consolidate networks along with servers– Technologies and standards are mature– Savings are real– Products are there

• You can get there from where you are today– Not just for green-field data centers– Gradual transitions reduce risk– Server virtualization smoothes the

transition
