Hp has all the ingredients for software defined networking, almost - Magnesium Ferro Silicon

"We see thecontrol plane as something that goes beyond just that and obviouslywe see the control plane as very important part of the network andof CI. It's very important." Converged Infrastructure is HP's strategy to create virtual pools of server , storage and networking resources to run business operations. SDN orchestration is pretty much all set, and again, it reachesbeyond just the networking infrastructure. Mayer said HP's VirtualApplication Network, which she discussed in her Interop keynote address this week , is an example of SDN orchestration.

"We already have quite a bit of orchestration, not just innetworking but in the larger enterprise group - with CloudSystemMatrix capabilities," she said. "Our Intelligent Management Centerhas integration with CloudSystem Matrix." "One of the benefits of HP, for networking and for servers andstorage, is that we can orchestrate everything in theinfrastructure and automate an awful lot more than othercompetitors or other vendors can. We can do integratedorchestration across all of our products." Mayer added that acceptance of HP's new 5900 top-of-rack 10G data center switch has been positive globally. The 24- to 48-port switch with40G uplinks debuted last fall, filling what had been a significantgap in HP's data center switching portfolio.

Gillai said the 5900 will soon receive software enhancements thatenable it to "operate in an interesting fashion" with HP servers. "We have bigger plans for some of the features that will be on thatplatform, in terms of how we continue evolving our ConvergedInfrastructure," he said, without going into specifics, thoughsuggesting that HP's Virtual Connect technology could be an exampleof how it plays out. Virtual Connect is designed to automate the process of connectingservers to networks and storage. Enterprises can reconfigureconnections to LANs and storage-area networks by, for example,moving workloads or adding and replacing servers on the fly. In the data center core, HP is in no rush to add TRILL to its 12500switch.

TRILL is an IETF specification for multipath Ethernetforwarding in data center and cloud fabric architectures. Seven months ago, HP added the capability to bind four of theswitches together into a single logical unit with its IntelligentResilient Framework (IRF) technology so customers, like DreamWorksAnimation, have been satisfied with that. "We said we were going to implement (TRILL) this year, and thatcontinues to be the plan," Mayer said. "But I would also say thatIRF is pretty extensible and so we just haven't had people turningthis down because we don't have TRILL." The 5900 is also designed to support TRILL.

Also coming, perhaps this year, for the 12500 are 40G Ethernetports. Further down the road are 100G Ethernet links but HP's in nohurry if the demand is not there, even though competitor Huawei is showing a switch at Interop it says is capable of supporting 96100G ports. "We don't need bragging rights for 100G, we have customers," Gillaisaid. "I could use it for a switch interconnect but it's a veryexpensive port for an interconnect."
