The Arista 7050 series 40G switches oﬀer wire speed layer 2/3/4 performance with 16 ports of 40GbE or 64 ports of 10GbE in a compact 1RU chassis. The 7050Q-16 switch oﬀers 16 QSFP+ interfaces and an additional 8 SFP+ ports shared with 2 QSFP+ ports for flexible support of 10GbE short and long reach interfaces.
Each QSFP+ supports wire speed 40GbE and can also operate as four independent 10GbE ports to provide a total of 64 10GbE ports. The Arista 7050Q oﬀers latency of 800 ns in cut-through mode, and a shared 9 MB packet buﬀer pool that is allocated dynamically to ports that are congested. With typical power consumption of less than 3 watts per 10G port, the 7050Q 40G switches provide industry leading power eﬃciency for the data center. An optional built-in SSD supports advanced logging, data captures and other enhanced services directly on the switch.
The 7050Q switch shares a common architecture with other members of the Arista 7050 Series providing a consistent level of performance, scale and resilience. The 7050Q delivers line rate 40GbE performance enabling scale out of Leaf-Spine designs with 40GbE links between the tiers and direct connection to 40Gb servers and storage devices. The Arista 7050Q-16 provides scalability improvements in dense leaf and spine architectures with support for 40GbE for link aggregation and a reduction in link serialization delays.
The Arista 7050Q switches run the same Arista EOS software as all Arista products, simplifying network administration. With Arista EOS, advanced monitoring and automation capabilities such as Zero Touch Provisioning, VM Tracer and Linux based tools can be run natively on the switch.
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. Several Linux based tools can be run directly on the switch, running on a powerful dual-core x86 CPU subsystem.
