HP本周将其开关线刷新，并使用三个新系统和路由器强化其SDN产品组合，以及管理和配置软件扩展。
The new offerings are designed to better meld the physical with the virtual in data centers, SDNs and clouds, territory very hot right now in Ethernet switching. Brocade is rolling out asimilar hardware/software combination，思科，阿雷斯塔，杜松和所有主要的交换竞争对手都是设计软件定义的面料.
HP's is hardware-intensive this time around. In the core, HP unveiled the FlexFabric 12900, 16- and 10-slot chassis that are OpenFlow 1.3-enabled and can support up to 36Tbps of non-blocking fabric switching, according to HP. The 12900 sports up to 768 10G and 256 40G Ethernet ports, with IEEE Data Center Bridging and ANSI以太网上的Fibrechannel.support and in-service software upgradability.
The 12900 also supports industry-defined fabric technologiesTRILL and Shortest Path Bridging，其中替换生成树的多个活动路径拓扑，针对数据中心机架之间的东西流量流动优化。雷竞技电脑网站

12900针对思科的Nexus 7000“F”和“M”开关，以及Juniper's QFabric and EX9200.
In the aggregation layer, HP unveiled the 11908 switch, which is also supports OpenFlow 1.3. The 11908 features a 7.7Tbps non-blocking fabric that can support up to 384 10G and 64 40G Ethernet ports. Like the 12900, the 11908 also supports TRILL and SPB fabrics, FCoE and Data Center Bridging, and in-service software upgrades.
The 11908 is also aimed at Cisco's Nexus 7000 and Juniper's QFabric. HP claims a fourfold increase over Juniper in 10G fabric density -- 24,000 to 6,000 -- and twice that of Cisco.

HP also unveiled a virtual switch to run under server hypervisors. The FlexFabric Virtual Switch 5900v supports the IEEE's Ethernet Virtual Bridging -- a.k.a. "VEPA." -- standard for offloading some switching capabilities from the server to a physical switch. The 5900v is optimized for VMware environments and supports mobility and management of network policies for virtual machines configured through VMware hypervisors.
The new router is called the HSR 6800. It combines routing, firewalling and VPN in a system with a 2Tbps backplane and 420Mpps of routing throughput. It supports 32 10G Ethernet ports and 687 microseconds recovery through HP's Intelligent Resilient Framework virtual chassis capability.
The HSR 6800 is also "40/100-ready," HP says. It will go up against Cisco's ASR 1000 router.
HP also rolled out a software-based router for virtually connecting branches and campuses to the cloud. The Virtualized Services Router is based on HP's Comware 7 software and is intended to be a readily deployable router for enterprises hosted in multitenant clouds.
对于管理，HP的新软件包括其智能管理中心系统的两个应用程序：虚拟应用程序网络资源自动化管理器和IMC SDN Manager。
VAN Resource Manager is a policy-based network automation tool for application service profiles. It is intended to improve service deployment and provisioning accuracy for faster service rollout. HP says it provides policy-driven resource management from access to core.
HP SDN Manager provides configuration, monitoring and policy management for SDN switches and controllers. It provides performance management of SDN controllers, is a single application that can govern both traditional and software-defined networks, the company says.
HP also rolled out three new services to aid customers in deploying virtualized data center and cloud networks. They include IT-to-business network transformation, IPv6 roadmap and data center network troubleshooting services.
HP FlexFabric 12900 switches are expected to be available in October. HP says pricing will be available at that time. The 11908 switch is expected to be available worldwide in June at a starting price of $83,000.
预计Virtual Switch 5900V将于10月份提供。定价当时将可用。HSR 6800路由器系列现已上市，起价为46,000美元。
The Virtualized Services Router series is expected to be available in the second half of 2013. Pricing will be available at that time.
Virtual Application Network Resource Automation Manager and SDN Manager are expected to be available in December 2013. Pricing will be made available at that time, HP says.
