Description
Model Overview
The 7260QX-64 is a 2RU system with 64 fixed ports of 40GbE QSFP+ in a power efficient system with overall throughput of 5.12Tbps and up to 3.3Bpps of forwarding at both layer 2 and layer 3.
The Arista 7260QX switches offer low latency from 550ns in cut-through mode, and a shared 16 MB packet buffer pool that is allocated dynamically to ports that are congested. Consistent features to the 7060CX and 7260CX combined with low power and high 40GbE density means the 7260QX is optimized for 40GbE top of rack and spine tiers, high density storage and financial trading systems. All members of the 7060X and 7260X Series provide 2 SFP+ ports that enhance the 40GbE and 100GbE capacity and allow direct 10GbE and 1GbE connections using a comprehensive range of transceivers and cables.
Overview
Increased adoption of high performance servers coupled with applications using higher bandwidth is accelerating the need for dense 40 and 100 Gigabit Ethernet switching in both leaf and spine tiers of modern networks. The Arista 7060X and 7260X Series are purpose built high performance, high density, fixed configuration, data center switches with wire speed layer 2 and layer 3 features, combined with advanced features for software defined cloud networking and emerging requirements. The Arista 7060X and 7260X are key components of the Arista portfolio of data center switches delivering a rich choice of interface speed and density allowing customers to seamlessly evolve from existing 10GbE and 40GbE to 25GbE, 50GbE and 100GbE.
The 7060CX-32S and 7260CX-64 support a flexible combination of speeds including 10G, 25G, 40G and 100G in compact form factors that allows customers to design networks to accommodate the myriad different applications and east-west traffic patterns found in modern data centers whilst providing investment protection.
The 7260QX Series are purpose built high density and low power 40GbE systems that enable cost effective solutions with flexible and scalable resources for layer 2 and layer 3 designs.
Combined with Arista EOS both the 7060X and 7260X Series deliver advanced features for cloud, big data, virtualized and traditional data centers.
Arista EOS
The Arista 7060X and 7260X run 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.
