It\u2019s fair to say that there has never been a bigger driver of network evolution than the cloud. The reason for this is the cloud is a fundamentally different kind of compute paradigm, as it enables applications, data and architecture changes to be done seemingly instantly. Cloud-native infrastructure is what enables mobile app developers to roll out new versions daily if they so choose.\nThe cloud is network-centric\nAnother fact about the cloud is that it is a network-centric compute model, so a poorly performing network leads to equally poorly performing applications. A lack of network agility means DevOps teams need to sit around twiddling their thumbs while network operations make changes to the network.\u00a0\n\nThis has been the driving force behind Arista\u2019s software-first approach since the company launched many years ago. It\u2019s EOS operating system was designed to be portable, so the company has been able to deliver a consistent set of features through different silicon releases without disrupting the operational processes of the networking team.\nOften organizations will hold off upgrading the network because their vendor made a major change to the OS, requiring scripts, tools, and management systems to be updated. But Arista has maintained a single OS across all its products.\nNew Arista switches leverage latest Broadcom silicon\nArista recently announced two new series of switches that increase scale and performance of the network while maintaining operational consistency.\nThe Arista 7050X3 and 7260X3 series are fixed form factor, leaf-and-spine products that use the Broadcom Trident 3 and Tomahawk 2 silicon.\nThe 7050 is more of a general-purpose switch and geared for enterprises that are running highly virtualized and\/or containerized data centers. The series comes in two flavors \u2014 one switch has 48 25 Gig-E ports with 12 100 Gig-E uplinks, and the other offers 32 100 Gig-E ports. It\u2019s optimized for complex layer 2 \/ layer 3 processing and tunnel encapsulation\/decapuslation, and it is an ideal product to implement security policies required at the server point of entry into the network.\nThe 7260 is suited for cloud providers or very large enterprises that have similar requirements and has a whopping 64 100 Gig-E ports in 2 RU form factor. It\u2019s designed to be a data center leaf-and-spine switch and is optimized for simple layer 3 processing and tunnel transit.\nThese new switches are also double the capacity of the previous generation, 7060X and 7050X.\n Arista\nNew features in Arista's\u00a07050X3 and 7260X3\u00a0switches\nWhile the operational model for Arista products remains consistent from switch to switch, the company is always adding new features to its products. This release was no different. Innovations in the 7050X3 and 7260X3 include:\n\nIntelligent buffering and congestion-aware automated load balancing for consistent network performance\nPath and latency monitoring with advanced packet tracing to find problems faster\nNetwork segmentation, including segment routing and full VXLAN support for tunnel encapsulation\nHigh availability with hitless software upgrades, speed changes, and flexible services with zero downtime\nUp to 12.8 Tbps and 4.2Bpps of packet forwarding\n\nThe new X3 series maintains the consistency of EOS but adds a wide range of features made available in the new Broadcom silicon. Arista customers can leverage the programmability of the platforms to run their own extensions to deliver unique capabilities. This provides the benefits of software without having to maintain a custom operating system.\nArista certainly isn\u2019t for everyone. But for customers that require leading-edge performance combined with programmability and agility, the company has provided a consistent drumbeat of new products leveraging the latest silicon.
