Arista DCS-7508 Data Center Switch Chassis 7500E-SUP 4x PWR-2900AC 6x 7508E-FM In Good Condition, Full Working Order Tested 2 Year Warranty Includes 2-Post Rack Mount Centre Brackets (No Screws Included) Included:
Overview: Designed for large virtualized data centers and cloud networks the Arista 7500 Series modular switches are the industry’s highest performance data center switches, available in a compact 7RU (4-slot) or 11RU (8-slot) they combine scalable L2 and L3 resources with advanced features for network monitoring, precision timing, network virtualization to deliver scalable and deterministic network performance for mission critical data centers, enterprise and HPC environments. The Arista 7500E is the second generation of the 7500 Series and delivers seamless upgrades ensuring investment protection of first generation fabrics, line cards and common equipment while setting a new standard for performance, density, reliability, and power efficiency. The Arista 7500E Series offers over 30Tbps of total capacity for 1,152 ports of 10GbE or 288 ports of 40GbE and support for 96 ports of wire-speed 100GbE with a broad choice of interface types that support flexible combinations of 10G, 40G and 100G modes on a single port. With front-to-rear airflow, redundant and hot swappable supervisor, power, fabric and cooling modules the system is purpose built for data centers. The 7500E Series is energy efficient with typical power consumption of under 4 watts per port for a fully loaded chassis. All of these attributes make the Arista 7500E an ideal platform for building reliable, low latency, resilient and highly scalable data center networks. Description: 7500 Chassis - 8-slot and 4-slot The 7500 chassis provides room for two supervisor modules, four or eight line card modules, four power supply modules, and six fabric modules. The 7504 chassis fits into 7 rack units while the 7508 chassis fits into 11U of a standard data center rack. Supervisor and line card modules plug in from the front, while the fabric and power supply modules are inserted from the rear. The midplane is completely passive and provides control plane connectivity to each of the fabric and line card modules. The system design is optimized for data center deployments with front-to-rear airflow. 7500E Supervisor Module The supervisor modules for the 7500 series run Arista Extensible Operating System (EOS) and handle all control plane and management functions of the system. One supervisor module is needed to run the system and a second can be added for stateful 1+1 redundancy. Each supervisor module takes up only a half slot resulting in very efficient use of space and a higher density design. The quad-core x86 CPU with 16GB of DRAM and an optional SSD provides the control plane performance needed to run an advanced data center switch scaling to over 1,000 physical ports and thousands of virtual ports. A pulse per second clock input port enables synchronizing with an external source to improve the accuracy of monitoring tools. 7500E Fabric Module At the heart of the 7500E series is the fabric. It interconnects all line cards in a non-blocking architecture irrespective of the traffic pattern providing a full 5.12 Tbps per fabric module. Each line card module connects to the fabric with multiple links and data packets are spread across the links to fully utilize the fabric capacity. Unlike hash-based selection of fabric links, the 7500E architecture provides 100% efficient connectivity from any port to any other port with no drops. The fabric modules are always active-active, provide N+1 redundancy and can be hotswapped with zero performance degradation. The Fabric Modules for the 7508E and the 7504E are different based on the size of the chassis and both integrate a fan assembly for flexible and redundant cooling. 7500E Power Supply Module The 7500E series switches are equipped with four 2900W AC power supplies. The power supplies are 2+2 grid redundant and hot-swappable. The power supplies are gold climate saver rated and have an efficiency of over 90% with single stage conversion to the internal 12V DC voltage. Compatible Line Cards:
