• Cost

• Speed

• Technologies

Remaining/upcoming challenges• Speed : 40G and 100G• Latency : cut-through techniques and Silicon

improvements• Lossless : CEE (2011)• High availability : loop avoidance techniques

TRILL is a proposed standard – proprietary techniques in the meantime

• Server virtualisationApps spread across multiple nodes : low latency/high speed/very large domain

Security/Mgmt/Troubleshooting virtual switches & vNICs : VEPA

Workload mobility : detect/log/adapt configuration/follow the VM

Ability to plum any subnet to any server in any rack : very large domain

10Gb growth at the edge brings new topology approaches

• 10G low-cost connectivity will evolve repeatedly for the next 3 years• Home-runs directly to core switches carry huge optics cost with 10G• Using TOR/Pod-based switches greatly reduces 10G costs

10G Home run approach (up to $4k more per server!)10G Pod-based (6600) approach

• Automated, policy-based provisioning of network and server resources

• Formalizes common data center workflow activities without organizational disruption

• Eases compliance and troubleshooting in a virtualized, complex environment

• Works with multivendor environments (servers and networks)

Network Team•Provide appropriate connectivity, security, bandwidth•Network level resiliency, load balancing, firewall

Server Team•Provide hardware resources, virtualization, backup and restore •Typically owns application deployment

Storage Team•Provide appropriate storage for application directly or server•RAID and resiliency / backup settings

Compliance Team•Crucial to large DC or specific ‘production’ environments (FSI etc)•Ensures compliance to security, asset management, or regulatory standards

• Manual, reactive, ‘discovery-based’ processes between IT Tech teams• As application provisioning and change volume increases these processes do not scale• Troubleshooting becomes difficult with no centralized information for an application’s total infrastructure requirements

Typically, network elements are plumbed statically with standard configurations

Then servers are applied to the plumbingvia their own element management. Customizing

network config and server config together is still manual.
