The Arista 7250QX-64 is a key component of the Arista portfolio of data center switches. The Arista 7250QX-64 fixed configuration switch shares common features with the Arista 7050 and 7300 X-Series of purpose built 10/40GbE switches, with wire speed layer 2/3/4 performance combined with low latency and advanced features for software defined cloud networking.
Increased adoption of 10 Gigabit Ethernet servers coupled with applications using higher bandwidth is accelerating the need for dense 10 and 40 Gigabit Ethernet switching. The 7250X Series supports a flexible combination of 10G and 40G in a compact form factor that allows customers to design both large leaf and spine networks to accommodate both east-west traﬃc patterns and support the requirement for low latency and power eﬃciency in dense servers farms.
With 64 QSFP+ ports the 7250QX-64 is a dense 40GbE system that can support a flexible combination of up to 64x 40GbE or 256 x 10GbE of wire speed performance in a 2RU system. The Arista 7250QX-64 combines low latency, and a shared packet buﬀer pool of 12MB per group of ports that is allocated dynamically to ports that are congested.
Combining 40GbE density and industry leading power eﬃciency with typical power consumption under 14W per 40GbE port the 7250QX-64 is ideal for both middle or end of row leaf or collapsed spine tiers with airflow choices for back to front, or front to back. An optional built-in SSD supports advanced logging, data captures and other services directly on the switch.
Combined with Arista EOS the 7250QX-64 delivers advanced features for big data, cloud, virtualized and traditional designs.
The Arista 7250QX-64 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, VMTracer and Linux based tools can be run natively on the switch with the powerful x86 CPU subsystem.
