Arista solutions range from OVSDB and Openstack integration to BGP EVPN in conjunction with EOS CloudVision®, a platform for network-wide workload orchestration and work ow automation. The 7280R3 builds on the deep bu er wire-speed gateway with EVPN/VXLAN for layer-2 and layer-3 stretch within data center as well as DCI use cases. The 7280R3 is the perfect solution for transit gateway between EVPN domains connected over MPLS. 7280R3 Deterministic Network Performance The Arista 7280R3 Series uses a deep bu er virtual output queue (VOQ) architecture that eliminates head-of-line (HOL) blocking and virtually eliminates packet drops even in the most congested network scenarios. An advanced tra c scheduler fairly allocates bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, xed priority, or hybrid schemes. As a result, the Arista 7280R3 can handle the most demanding data center requirements with ease, including mixed tra c loads of real-time, multicast, and storage tra c while still delivering low latency. 7280R3 Series | Technical Speci cations Algorithmic ACLs Algorithmic ACLs combine both software and hardware to enable more exible and scalable solutions for access control, policy based forwarding and network telemetry. Combining general purpose memory with advanced software algorithms delivers higher scale, performance and e ciency with lower power and is more cost e ective than traditional solutions. Algorithmic ACLs leverage e cient packet matching algorithms that in turn enables ow matching for access control, policy and visibility. The net bene ts are a high performance policy engine with both increased functionality and scale in a cost and power e cient solution. Algorithmic ACLs are available on the 7280R3 and 7280R3K Series of products. · Enables IPv4 and IPv6 access control at the same scale · L4 rule ranges are programmed e ciently without expansion or reduced capacity · Multiple actions can be performed on a single packet or ow · User de ned lters allow exible packet classi cation based on o sets for custom actions · Supports rich policy with consistent semantics that would exhaust classical resources Inband Network Telemetry Inband network telemetry, or INT, is a standards approach to providing deep visibility into tra c in real-time, with no impact on switch performance. INT provides per- ow monitoring of tra c drops, latency, congestion and the network path. INT information can be exported in IPFIX or sFlow formats to a management system or collector such as Arista CloudVision, for predictive analytics and deep forensics to measure latency per device and across the network, trace packets and reconstruct path topology as well as detecting hotspots. Inband Network Telemetry is available on the 7280R3 and 7280R3K Series of products, with the ability to originate, pass and terminate, along with mirroring to external collectors. 7280R3 Accelerated sFlow SFlow is a powerful tool used commonly by network operators for advanced network telemetry, capacity planning, security analysis and quality of experience monitoring. Traditional sFlow utilizes a system CPU for processing samples of hundreds of thousands of ows. In modern high performance systems guaranteed high rate sampling requires the capability to both sample and process packet rates of billions of packets per second. With the 7280R3 Series Accelerated sFlow feature the sampling and processing of ow samples into sFlow datagrams is handled via integrated sFlow engines capable of supporting 1:500 sampling rates on full wire speed systems or higher rates with selective sampling based on triggers and lters. All sFlow v5 information is included in the sFlow records ensuring consistent integration with existing standard sFlow collection and analysis tools and no loss of information.
