7010X Series | Platform Overview

Out of Band Networks

The 7010X provides for the consistent application of access controls, network security features, virtualization and remote monitoring

features to protect access to both dedicated management interfaces and restrict access to authorized users of out-of-band networks.

Intelligent Platform Management Interfaces (IPMI) on servers provide a standard interface for complete system management including

startup, management, maintenance and shutdown over standard Ethernet networks. Access to the IPMI ports allows for privileged

access and full control of the server. The Arista 7010X with EOS provides rich features that are applied to both the management

networks and the production data center networks consistently across the range of Arista 7000 Series switches and routers.

Dynamic Buffer Allocation

The Arista 7010X switches forward packets with a consistent low latency of under 3 microseconds. Upon congestion, the packets are

buffered in an intelligent fully shared packet memory that has a total size of 4MB for burst absorption. Unlike other architectures that

have fixed per-port packet memory, the 7010X Series use dynamic thresholds to allocate packet memory based on traffic class, queue

depth and quality of service policy ensuring a fair allocation to all ports of both lossy and lossless classes. Buffer utilization, occupancy

and thresholds are all visible with Arista LANZ and can be exported to monitoring tools to identify hotspots and measure latency at the

device and end to end.

Maximum Flexibility for Scale Out Network Designs

Scale out network designs enable solutions to start small and evolve over time. A simple two-way design can grow as far as 64-way

without significant changes to the architecture. The Arista 7010X Series include enhancements for flexible scale-out designs:

• 64-way ECMP and MLAG to provide scalable designs and balance traffic evenly across large scale 2 tier leaf-spine designs

• Equal and Unequal Cost Multi-Pathing (UCMP) for flexible traffic balancing in large scale multi-tier topologies

• Comprehensive L2 and L3 forwarding table resources for more design choice

• Wide choice of dense 1G/10G/25G interfaces for multi-speed flexibility

• Support for standards based IEEE 25GbE for simple and cost effective migration from 10G to 25G

• VXLAN routing, bridging and gateway capability for physical to virtualization communication in next generation data center designs

• DANZ, sFlow and multi-port mirroring to detect micro-burst congestion and provide network wide visibility and monitoring

• Hitless speed changes to eliminate down-time when implementing speed changes on any ports.

• PTP support for for advanced visibility and monitoring.

Smart System Upgrade *

Smart System Upgrade is a network application designed to address one of the most complicated and challenging tasks facing data

center administrators - network infrastructure maintenance. Changes to the underlying network infrastructure can affect large numbers

of devices and cause significant outages. SSU provides a fully customizable suite of features that tightly couples data center

infrastructure to technology partners allowing for intelligent insertion and removal, programmable updates to software releases and

open integration with application and infrastructure elements.

Virtualization

The foundation for Arista's Network Virtualization solutions is VXLAN, an open IETF specification designed to standardize an overlay

encapsulation protocol. Arista solutions range from OVSDB and Openstack integration to BGP EVPN in conjunction with EOS

CloudVision®, a platform for network-wide workload orchestration and workflow automation. The 7010X builds on the wire-speed

gateway with EVPN/VXLAN for layer-2 and layer-3 stretch within data centers and make integration of non-VXLAN aware devices

including servers, firewalls and load-balancers seamless.

Precise Data Analysis

Arista Latency Analyzer (LANZ) is an integrated feature of EOS. LANZ provides precise real-time monitoring of micro-burst and

congestion events before they impact applications, with the ability to identify the sources and capture affected traffic for analysis.

Advanced analytics are provided with features like buffer monitoring with configurable thresholds, in-band path and latency

monitoring, event driven trace packets and granular time stamping.
