Switch Arista DCS-7260CX3-64E-R

The ARISTA 7260 series switches are highly productive network equipment designed for modern data processing centers and cloud architectures, where high bandwidth, tuning flexibility and minimal delay are critically important.. These are Date Center devices that maintain data rate of 25, 40, 50 and 100 gigabits per second on each port. Thanks to this, one switch is able to replace a few less powerful solutions by optimizing network infrastructure and reducing energy consumption.

A specific model from the Arista 7260 line is equipped with up to 64 ports QSFP, Each of which can operate at 100G speeds or be divided with a Breakout cable into four separate channels on 25G. Thus, the total number of logical ports can reach 256 when using all physical interfaces as a branch. This is especially important in the conditions of flexible switching of a large number of servers, storage systems or other networks with high traffic density.

The total bandwidth of the device reaches 12.8 therabs per second that allows you to process huge data streams without the appearance of "narrow places». Built -in 22 megabytes buffering system dynamically distributes the memory between port. This is especially true for real -time programs as well as for virtualized media >by the audible behavior of traffic.

One of the key technical parameters of this series is ultra -delay. Depending on the model and configuration, the delayed packet transmission from the port to the port is less than 3 microseconds. This makes equipment suitable even for such demanding tasks as processing financial transactions, systemic integration of industrial IOT devices and support of critical services.

The switch is built -in high -performance controller with the volume. This provides reliable storage of logs, configurations and updates, and also allows to start complex network services without the need to connect external equipment. Under the control of the device is a corporate operating system Arista EOS, which is characterized by high stability, a wide command set, and configuration automation capabilities through API and third -party control systems such as Ansible or Puppet.

Physical performance of the switch includes the intellectual cooling system with the ability to choose the direction of air flow (forward or backward), which is convenient when installing racks with different ventilation types. Supports hot swapping of power supplies and fans, allowing maintenance without stopping the network.

The switch is compatible with a wide range of optical and copper modules — QSFP+, QSFP28, as well as with straight and active cables DAC and AOC. This ensures the versatility of using different types of networks: from hyperconvertent infrastructure to main transmission channels between distant Date Centers.
