Arista Unveils Industry’s First Leaf Switch With 100GbE Uplinks

Arista Networks (NYSE: ANET) today announced the 7280E Series fixed leaf switches, along with monitoring and automation enhancements to Arista EOS®, continuing the evolution of software driven cloud networking. This new family of switches with its ultra-deep packet buffers and 100GbE uplinks enhance application performance, while providing resiliency, programmability and visibility into the network.

EOS Smart System Upgrade (SSU), now available for both Spine and Leaf switches, allows enterprises to perform hitless software upgrade across the entire network. Automation via EOS eliminates planned downtime and allows for 24x7x365, cloud-like uptime for in-house applications.

Optimal for Storage and Big Data

The 7280E Series extends the Arista leaf switch portfolio with a 1000x increase in packet memory, compared to typical switches in top-of-rack applications. This ability to handle network congestion results in a low loss network for critical workloads such as IP Storage, Big Data and streaming video. The same EOS binary image runs across all Arista products and includes support for VXLAN, LANZ, DANZ and Arista Tracers on these new platforms, lowering the certification and overall Opex for enterprises.

“The eBay storage environment is network intensive and requires switches that are architected for these unique requirements,” said Russ McElroy, Senior Manager of eBay Marketplaces and PayPal. “The Arista 7280E 10/40/100GbE systems have ultra-deep buffers and are optimized for intensive workloads such as storage.”

TAP Aggregation and Visibility

Arista Data Analyzer (DANZ) feature set that provides real-time monitoring capabilities, is now available on the 7500E modular spine switches, providing visibility at 10/40/100GbE speeds at terabit capacity. New features in EOS include a Tap Aggregation Manager, Deep Packet Inspection (DPI) and advanced traffic steering that allows network operators to precisely select the flows that need monitoring.

Additionally, the addition of OpenFlow 1.3 support for the 7500E enables research centers and universities to deploy 100GbE networks interconnecting to Internet2 for bulk data transfers.

Universal Optics reduce fiber need by 75%

Other announcements include a standards compliant universal optic that enables 40GbE over a single pair of either multi-mode or single-mode fiber, enabling seamless and cost-effective migration from 10 to 40GbE. The Universal QSFP optics have a reach of 150m over multi-mode fiber and 500m over single mode fiber, and can also interoperate with IEEE LR4 based devices.


The Arista 7280E switches are in customer trials now with general availability in August 2014. The Universal 40GbE transceiver is orderable now. SSU feature set for 7050X leaf switches is available in beta releases now and generally available by late 2014.

There are many considerations when moving applications from on-premise to cloud. It is critical to understand the benefits and also challenges of this migration. A successful migration will result in lower Total Cost of Ownership, yet offer the same or higher level of robustness. Migration to cloud shifts computing resources from your data center, which can yield significant advantages provided that the cloud vendor an offer enterprise-grade quality for your application.
The web app is agile. The REST API is agile. The testing and planning are agile. But alas, data infrastructures certainly are not. Once an application matures, changing the shape or indexing scheme of data often forces at best a top down planning exercise and at worst includes schema changes that force downtime. The time has come for a new approach that fundamentally advances the agility of distributed data infrastructures. Come learn about a new solution to the problems faced by software organ...

You have your devices and your data, but what about the rest of your Internet of Things story? Two popular classes of technologies that nicely handle the Big Data analytics for Internet of Things are Apache Hadoop and NoSQL. Hadoop is designed for parallelizing analytical work across many servers and is ideal for the massive data volumes you create with IoT devices. NoSQL databases such as Apache HBase are ideal for storing and retrieving IoT data as “time series data.”
In recent years, at least 40% of companies using cloud applications have experienced data loss. One of the best prevention against cloud data loss is backing up your cloud data. In his General Session at 17th Cloud Expo, Bryan Forrester, Senior Vice President of Sales at eFolder, will present how organizations can use eFolder Cloudfinder to automate backups of cloud application data. He will also demonstrate how easy it is to search and restore cloud application data using Cloudfinder.
