Arista EOS

The Arista 7280E runs the same Arista EOS software as all Arista products, simplifying network administration. Arista EOS is a modular switch operating system with a unique state-sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multiprocess state-sharing architecture provides the foundation for in-service software updates and self-healing resiliency. 

With Arista EOS, advanced monitoring and automation capabilities such as Zero Touch Provisioning, VMTracer, and Linux-based tools can be run natively on the switch with the powerful quad-core x86 CPU subsystem.

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 evolve without significant changes to the architecture. The Arista 7280E includes enhancements that allow for flexible scale-out designs:

• 128-way ECMP and 128-way MLAG to provide scalable designs and balance traffic evenly across large scale two-tier leaf-spine designs
• VOQ architecture and deep packet buffering to eliminate head of line blocking
• Flexible allocation of L2 and L3 forwarding table resources for more design choice
• Wide choice of dense 10/40/100 Gb ports for single port multispeed flexibility
• VXLAN routing, bridging, and gateway for physical to virtualization communication to enable next generation data center designs
• LANZ, DANZ, PTP, sFlow, and multiport mirroring to detect micro-burst congestion and provide network-wide visibility
• ACL scalability with up to 12K entries per forwarding engine and 36K ACL entries per module

Arista leaf-spine two-tier network architecture

Software-defined networking

Arista Software-Defined Cloud Networking (SDCN), combines the principles that have made cloud computing the unstoppable force that it is: automation, self-service provisioning, and linear scaling of both performance and economics coupled with the trend in software-defined networking that delivers: network virtualization, custom programmability, simplified architectures, and lower capital expenditure. This combination creates a best-in-class software foundation for maximizing the value of the network to both the enterprise and service provider data center. A new architecture for the most mission-critical location within the IT infrastructure that simplifies management and provisioning, speeds up service delivery, lowers costs, and creates opportunities for competitive differentiation, while putting control and visibility back in the hands of the network and systems administrators.

Enhanced features for high-performance networks

The Arista 7280E delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high-performance environments, with solutions for data monitoring, precise timing, and next-generation virtualization.

Precise data analysis

Arista Latency Analyzer (LANZ) and precision Data Analyzer (DANZ) are integrated features of EOS. DANZ provides a solution to monitoring and visibility challenges at 10/40/100 Gbps, giving IT operations the ability to proactively deliver feedback on congestion events, filter, replicate, aggregate, and capture traffic without affecting production performance. 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.

Precision timing (IEEE 1588)

The IEEE 1588 Precision Time Protocol enables building and maintaining an accurate timing solution that delivers highly accurate precision-time synchronization to sub-microsecond accuracy to applications within existing network infrastructure with no need to invest in and deploy a separate timing network. Arista's 7280E series hardware-assisted Precision Time Protocol solution provides a high- performance and robust mechanism for accurate in-band time distribution to servers, routers, and other switches.

Audio Video Bridging (AVB)

Audio Video Bridging (AVB) standards allow professional media to be reliably transported over an Ethernet network with the benefits of a packet-based infrastructure; greatly simplified cabling, great flexibility in signal routing and processing, and the advantage of extremely low costs due to the ubiquitous nature of Ethernet. The 7280E incorporates EOS support for IEEE AVB specifications for precise synchronization, traffic shaping, admission control, and device identification.

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7280E builds on the valuable tools already provided by the Arista VM Tracer suite to integrate directly into encapsulated environments. Offering a wire-speed gateway between VXLAN and traditional L2/3 environments, the 7280E makes integration of non-VXLAN aware devices including servers, firewalls and load-balancers seamless and provides the ability to leverage VXLAN as a standards-based L2 extension technology for non-MPLS environments.

Arista Event Management (AEM)

Simplifying the overall operations, AEM provides the tools to customize alerts and actions. AEM is a powerful and flexible set of tools to automate tasks and customize the behavior of EOS and the operation of the overall data center switching infrastructure. AEM allows operators to fully utilize the intelligence within EOS to respond to real-time events, automate routine tasks, and automate actions based on changing network conditions.

Flexible combination of 10/40/100 G

The 7280E delivers unprecedented levels of buffering, scale, and availability with high-density 10GbE interfaces and a choice of uplink interfaces as shown on the right from top to bottom:

Arista 7280E Flexible Port Combinations

• 7280SE-72: 2 MXP ports for 2 x 100 G, 6 x 40 G or 24 x 10 G
• 7280SE-68: 2 QSFP100 ports for 2 x 100 G, 2 x 40 G or 8 x 10 G
• 7280SE-64: 4 QSFP+ ports for 4 x 40 G or 16 x 10 G

Embedded optics combined with MPO interfaces provide a multispeed-port (MXP) capability that increases system density with a choice of 10/40/100 G interfaces. MXP ports support a mix and match option of 12 x 10 G, 3 x 40 G, or 1 x 100 G per port. With support for up to 400 m over multimode fiber MXP ports provide high-density and seamless migration from 10GbE to 100GbE without replacing transceivers or lowering system capacity.

QSFP100 ports enable a wide range of standards based 100G and 40G optics for both single and multimode fiber for distances up to 40km. Each interface can be configured independently for either 40G or 100G, or a 4x10G mode using breakout cables or optics.

QSFP+ ports enable the widest choice of copper, multimode, and single-mode optics with both 10GbE and 40GbE options using both duplex and parallel technology that reach up to 40km.

Deep buffers and deterministic network performance

The Arista 7280E series uses a deep buffer 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 traffic scheduler fairly allocates bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, fixed priority, or hybrid schemes including 802.1Qaz ETS. As a result, the Arista 7280E can handle the most demanding data center requirements with ease, including mixed traffic loads of real-time, multicast, and storage traffic while still delivering low latency.

High availability

The Arista 7280E switches were designed for high availability and simple provisioning from a software and hardware perspective. Key high availability features include:

1 + 1 hot-swappable power supplies and four N + 1 hot-swappable fans

Color coded PSU's and fans

Live software patching

Self-healing software with stateful fault repair (SFR)

Smart System Upgrade (SSU)
