A PICS Telecom 101 on the CAB-AC-20A-SG-C20-4M from the Arista 7800R3 Series.
The Arista 7800R3 Series of purpose built modular switches deliver the industry’s highest performance scaling to 460 Tbps of system throughput to meet the needs of the largest scale data centers. They combine scalable L2 and L3 resources and high density with advanced features for network monitoring, precision timing and network virtualization to deliver scalable and deterministic network performance while simplifying designs and reducing OpEx.
PICS Telecom offers the largest inventory of new and used multi-vendor telecom network products and data equipment. Providing critical spares and services to over 2000 customers in over 100 countries. All equipment provided is thoroughly tested to ensure it is in excellent working condition and is backed by PICS’ comprehensive warranty.
The 7800R3 Series offers architectural consistency to the 7500R and 7280R Series that ensures long term investment protection with support for deterministic fair delivery, flexible scale and open programmability building on evolution of the Arista R-Series delivered by the 7500 and 7280 Series.
The 7800R systems can accommodate any combination of the 7800R3 and 7800R3A line cards providing a choice of density, scale and speed, with all options including support for FlexRoute, Accelerated sFlow and Algorithmic ACLs.
The Arista 7800R3 lowers total cost of ownership as it is designed to be efficient with power per port as low as 25W per 100G port which combined with front to rear cooling to optimize the data center environment produces the most reliable, dense and power efficient modular switch.
The Arista 7800R 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, #xed priority, or hybrid schemes. As a result, the Arista 7800R 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.
