Arista EOS

The Arista 750 series 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 multi-process 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 and Linux-based tools can be run natively on the x86 CPU subsystem.

Model Overview

A choice of two Arista 750 Series systems and a range of PoE line cards (1G, 2.5G, 5G, 10G) provides flexibility for a wide range of campus design options. The 750 Series 8-slot system delivers up to 384 ports, and each line card provides 48 ports, all with PoE. Speed and capacity options allow for cost-effective future-proofing. Campus networks demand high availability, and the 750 system offers active-standby resiliency with fully independent control plane & data plane. Redundant switch cards and supervisors are combined with SSO. Active/standby switch cards enable hitless communication with Campus Spines & Splines. Complementing management & control plane redundancy, the 750 Series uses non-blocking, hot-swappable switch cards for end users and devices.

The 750 Series enables fully loaded 60W 802.3bt deployments for the latest WiFi 6 Access Points and other demanding applications. The 750 Series can also tunnel WiFi traffic directly using standards-based VXLAN, eliminating the need for expensive and proprietary Wireless anchor controllers.

Cognitive Power Management

Arista leverages state-of-the-art switch and power management technology to deliver enhanced power delivery options supporting the latest PoE standards, more efficiently and reliably than standard PoE delivery. This allows administrators to support more IoT and WiFi devices cost-effectively. Dynamic PoE management enhances power budgeting and allocation features to help economize power allocation to powered devices (PD) connected to each switch, dynamically allocating PoE power based on priority settings. Concurrent PoE leverages power supply load sharing and power allocation to all ports, allowing customers to share power within a system and utilize allocated but unused power to power more PoE devices. Continuous PoE provides power to the powered device (PD) connected to PoE ports even when the system is reloading, avoiding downtime and loss of service. CloudVision monitoring controls and reports instantaneous and peak power utilization levels in real-time with persistent logging, enabling administrators to accurately monitor and report service levels and infrastructure power demands.

750 Series Systems

The 750 Series are wirespeed, high-density 1G to 10G Modular PoE systems architected for today's needs and for many years to come. Delivered in a choice of 2 compact systems, the 750 Series 5-slot system supports up to 5 line cards and 2 management modules in just 7 rack units, while the 750 Series 8-slot model allows up to 8 line cards, also with dual management modules for high availability, in just 10 Rack Units.

750 Series Switch Cards

The 750 Series leverages a dedicated centralized switch architecture that provides high throughput, consistent low latency with low jitter, and high scale. The switch card runs the dataplane for all forwarding, with the management plane and control plane on the separate Supervisor module. With redundant switch cards, failover from active to standby occurs without a control plane change, increasing system reliability. Switch cards are hot-swappable and accessed from the system rear, avoiding any impact to network cabling during maintenance. The switch card provides up to 1.6Tbps of switching, 160K MAC addresses, and 160K IPv4 hosts, supporting the needs of the largest enterprises, with a fully shared 32MB packet buffer that accommodates traffic bursts and manages speed changes, as well as all packet processing for L2 and L3 forwarding, QoS, security policy enforcement, VXLAN, and EVPN segmentation.

Supervisor Modules

The 750 Series Supervisor module is a high-performance module common to both the 5-slot and 8-slot systems. It features a quad-core CPU, 16GB of memory, and an integrated 120GB SSD to run the 750 Series control plane and management plane. Each supervisor module includes high-performance uplinks with a choice of 10/25G SFP ports or 40/100G QSFP ports, supporting a wide range of optics and cables, including multi-rate and bidi, to facilitate easy integration to existing networks and allow for migration to 25G and 100G performance as needs evolve, with no change to existing fiber cabling. The Supervisor module uplinks are all active, even in a dual supervisor deployment, with no disabled ports. Uplinks also continue to be available during supervisor switchover or software upgrades with SSU. With dual supervisors, the aggregate uplinks can support 400Gbps of capacity for the most demanding wired and wireless access requirements. Additional local storage can be connected to the Supervisor module USB port, with a choice of SFP and RJ45 ports for Ethernet management.

Line Card Modules

The 750 Series line cards support a variety of interface speed and PoE combinations. The line cards all connect to the centralized switch cards, which perform the packet processing. Mixing and matching modules provides flexibility and pay-as-you-grow capacity. All traffic, even within a set of ports on a single line card, is handled by the high-capacity switch cards, ensuring feature consistency with a single set of logical resources and fully shared packet buffers.

All 750 Series line cards deliver PoE with a choice of 1G, mGig, and 10G-T. Up to 60W of 802.3bt PoE is supported with cognitive power management on all ports to dynamically manage power allocations and increase power efficiency based on detection of end-device state and network flows. The line cards support interfaces from 10Mbps to 10G, allowing connectivity for a broad range of devices.

• CCS 750 Series 48 Port 1G PoE linecard: 48 ports nonblocking, 10/100/1000 RJ45, 30W on all ports, MACsec on all ports.
• CCS 750 Series 48 Port mGig PoE linecard: 48 ports nonblocking, 100/1000/2.5G RJ45, 60W on all ports, MACsec on all ports.

Integrated MACsec Security *

The 750 Series supports encryption on all ports for dataplane security using industry-standard MACsec encryption that avoids common threats, including snooping, in a zero-trust environment. Every line card access port and supervisor uplink port supports 256-bit MACsec encryption to secure communications between MACsec-capable devices, including Arista's MACsec-capable WiFi access points, and to the network campus core. MACsec is a separately licensed feature for each system.

* Not currently supported in EOS

Power and Cooling

The 750 Series leverages a set of high-efficiency 3.3kW power supplies for both system power and PoE power. Load sharing and redundancy at both the power supply (N+1) and power source (N+N) level ensures the system is fully resilient to common failure modes. With up to 10 platinum-efficiency rated power supplies in a single system, the 750 Series is optimized for modern campus environments. Each power supply can operate on either 200-240V or 100-120V inputs.

With as few as two power supplies, the system is redundant. As additional power supplies are added, the system delivers up to 60W of PoE on all ports. The intelligent power management ensures the system prioritizes power to critical resources at all times, even during SW upgrades or reloads.

The 750 Series fan modules deliver cooling to the entire system and are incorporated into the switch cards, with an efficient front-to-rear airflow, common with the 720 Series fixed PoE switches. The compact design with integrated fans allows the 750 Series to occupy just 10U and 7U respectively. Fan modules are individually removable, providing support for simple servicing with hot-swap operation and no risk of system shutdown during maintenance windows. The 750 Series system has multiple temperature sensors monitoring critical resources and both inlet and exhaust air temperature. Fan speeds are dynamically adjusted by EOS to optimize system operation and reduce noise. The compact design of the 750 Series allows it to be installed in small wiring closets in both 2-post and 4-post racks, with front, center, or rear mounting options. Convenient handles are provided for use during installation and to simplify future moves, adds, and changes.

High Availability

The 750 Series enables highly available and reliable networks. The reliability model is based on dual redundant elements at all parts of the system, with centralized switch cards connected to the line cards, featuring no midplane or backplane, using direct orthogonal connections for higher performance. A fully shared buffer for all PoE and uplink ports eliminates oversubscription and inter-chip links. Dual switch cards, dual supervisor modules, and redundant connections between all parts of the control plane and the data plane complete the resilient architecture. The control plane and data plane are kept separate to further improve reliability; the switch card is dedicated to the data plane, and the management and control planes run on the supervisor modules' x86 CPU.

Telemetry

Network telemetry for unified edge with FlowTracker support, native in the Arista 750 Series, delivers real-time updates for all device state, performance statistics, and application flows. This supports Artificial Intelligence and Machine Learning mechanisms that reduce operational expense, decrease mean time to resolution, and enhance the network's ability to integrate wired and wireless telemetry, improving security and segmentation policies.

CloudVision

CloudVision is Arista's management plane solution for simplifying network operations. Built on a modern state-streaming architecture, CloudVision is a multi-function software platform that enables a suite of capabilities for automated provisioning, change control, continuous compliance, real-time telemetry, predictive analytics, and third-party management plane orchestration. As a multi-domain solution, CloudVision serves as a single management platform across data center, campus, WiFi, multi-cloud, and routing interconnect use-cases. The same CloudVision software is offered as an on-prem appliance (virtual or physical) as well as CloudVision as-a-Service, which is an Arista-managed SaaS solution.

Cognitive Segmentation

The 750 Series supports industry-standard 802.1X authentication schemes and interoperates with leading authentication solutions. Authorized users and devices can be automatically segmented into assigned 802.1Q or EVPN VXLAN segmented networks, facilitating infrastructure and data security. Wire-speed Layer 3 VRF segmentation is also supported, giving administrators additional flexibility for supporting the most sophisticated campus use cases. The 750 Series switches also assist administrators with WiFi segmentation by providing hardware-based VXLAN de-encapsulation of tunneled WiFi traffic.

Campus Overlay Scale

The 750 series switches utilize advanced virtualization features to provide hundreds of segmented networks to thousands of users and devices. In addition to 4K 802.1Q VLANs for uplinks, the 750 Series delivers 16K (port, VLAN) combinations for downlinks and 16.7 million VXLAN overlay networks with CVX and EVPN control plane support. The combination of virtualization scale plus the Layer 2 and Layer 3 hardware scale of the 750 series ensures administrators can implement large, segmented, and secure campus networks with the ability to scale in the future.

EOS Licensing

Arista 750 Series with EOS and CloudVision are designed to provide flexibility in the choice of appropriate feature functionality and in the software consumption model. The base feature set of Arista EOS comes bundled with Arista products and systems. A set of feature licenses are available to enable additional functionality in advanced feature sets. The traditional licensing procurement model employs a perpetual term for the right to use the feature, set at a fixed price.
