Arista says the 7500E can support more than a million VMs and software-defined automation through the switch's EOS (Extensible Operating System). Through EOS, the 7500E supports Aristas DANZ data analysis application for traffic visibility and tap-aggregation; RAIL (Rapid Automated Indicator of Link-Loss), for rapid convergence in big data analytics and Hadoop applications; VM Tracer, for network wide workload mobility; and Health Tracer, for switch-level diagnostics and traceability of key performance indicators.
The 7500E series switches and line cards are available now. List prices start at $99,995 for the switch and $10,000 per 100G port, $2,200 per 40G, and under $600 per 10G port.
Arista will have to fend off HP, which refreshed its switch line and fortified its SDN portfolio with three new systems and a router, along with management and provisioning software extensions.
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 FibreChannel over Ethernet support and in-service software upgradability.
The 12900 also supports industry-defined fabric technologies TRILL and Shortest Path Bridging, which replace Spanning Tree with a multiple active path topology optimized for east-west traffic flows between data center racks.
The 12900 is aimed at Cisco's Nexus 7000 F and M switches, and 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 Junipers 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, aka 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 420Mbps 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.
Analysts say HP's launch shows progress from the company in data center switching, and in its 4-year-old 3Com acquisition. "These are behemoths of switches, and [they] certainly give HP a product advantage," says Zeus Kerravala, principal analyst at ZK Research. "Also, the support for TRILL, SPB and DCB I thought was interesting as customers do not have to choose."
Still, there might be some gaps for HP to fill, Kerravala notes.
