Arista: Datacenter Fixed Switches with 400 G port Speed

Arista introduces 400GbE Leaf and Spine solutions for hyper scale cloud and I/O rigorous infrastructure. With the help of Arista’s 7060X4 Series data center switch which are high density and power effective fixed configuration you can get the throughput of 400GbE on ports.

With a demand of industry standard OSFP or QSFP-DD interfaces arista deliver a adaptable solution for the biggest hyper scale cloud and IO rigorous infrastructure. with reliable low latency collective with established visibility, traffic composition and automation descriptions.

The Arista’s 7060X4 Series bring wire speed layer 2 and layer 3 with stretchy resources, vigorous traffic management and load balancing features.

You can have 32 ports of 400GbE in fixed Arista which is 1RU model i.e. 7060PX4-32 and 7060DX4-32 maintenance a stretchy demand of port speeds from 128 x 100G to 32 x 400G, with each port associate a wide choice of optics and cables.

As we discussed, there are two models which Arista come up with the high port density of 400 Gb is 7060PX4-32 and 7060DX4-32. Now the question is what is the difference between these two switches. Let’s have a view on the difference between these switches.

Well although most of the features are the same like both support 32 number of ports with 400 Gb OSPF or QSFP-DD. If you would like to have 100 G of the ports you can get maximum of 128 ports of 100 G on both the switches. Making the use of the 50 G ports in the switch you can get maximum of 144 ports of 50 G on both the switches. Both switches will give you the L2/L3 throughput of 12.8 Tbps and latency of 700 Nano seconds.

Both these switches support AC and DC power supplies. Total buffer size of 64 Mbps on both the switches. These switches support maximum MAC table size of 72K and V4/V6 host of 80K. The maximum IPv4 route prefixes are 480K and IPv6 route prefixes up to 300K.

Both the switches support Multicast with LAG and ECMP. The difference is the power drawn, The Arista 7060PX4-32 will draw 640 W of power while Arista 7060DX4-32 will draw 690 W of power. The other difference is Arista 7060PX4-32 uses OSFP as 400 G SFP standards for 32 ports while Arista 7060DX4-32 uses QSFP-DD as 400 G SFP standards for 32 ports.

Arista comes in the league of the 400 G datacenter switching portfolio while Cisco, HP, Juniper and Huawei will soon come up in the competition with the 400 G port speed on the datacenter portfolio.
