Ethernet networks have evolved significantly since their inception back in the 1980s, with many generational changes to where we are today. Networks are orders of magnitude faster with 10Gbps line rate switching as the norm. Moreover, today’s Ethernet networks offer sub-microsecond switch latency, traffic scaling and load balancing across redundant interfaces, and are reducing the management complexities with state-driven architecture and open interfaces for managing hundreds of switches through global, yet highly secured interfaces. Software Driven Cloud Networking (SDCN) is a term often used when a controller external to the forwarding logic and the actual switch itself programs the network devices to alter or enhance the flow of traffic.
This paper provides an overview of SAN and NAS storage solutions, highlights the ubiquitous role of 10 Gigabit Ethernet in these solutions, and illustrates how Arista's 7000 series of switches directly address this market.
Networks designed in the late 90s primarily addressed static applications and email. The future of cloud networking optimizes the following variables: guaranteed performance, low latency and any-to-any communication patterns. Arista’s switching architectures and expanded 7000 family are designed to deliver the optimized cloud networking solution.
The combination of virtualization and cloud computing creates a computing paradigm that requires careful network considerations. A cloud network must support the abstraction of virtualization services from specific physical servers.
The drive for scalable and efficient cloud networks has led to 10Gb Ethernet as the interface of choice for simultaneously transporting data, storage and compute information over a common Ethernet cloud. Multiple classes of applications, rely on latency-optimized architectures for ultra fast response times.
Arista Networks and PacketLight Networks have jointly developed and tested a set of solutions that leverage Arista’s market leading 100GbE port density and the PacketLight Networks PL-1000GM and PL-1000T. These solutions deliver a series of cost effective and scalable distance extension and media conversion solutions.
Arista Networks and MRV have jointly developed and tested a set of solutions that leverages Arista switches’ market leading 100GbE port density and MRV's market leading Optical Transport series to deliver cost effective and efficient distance extension and media conversion solutions. Interoperability testing was performed with a MRV LambdaDriver 400L.
With the introduction of the Arista 7300 Series switches, Arista provides the flexibility to further collapse network layers with the introduction of the single-tier Spline™ (combined Spine/Leaf) network design.
The Arista 7250X and 7300 series are purpose built 10GbE/40GbE data center switches in four flexible energy efficient form factors, designed specifically to offer increased performance, scalability and density, without making any compromises to system availability, reliability or functionality.
While many customers will perform product testing this whitepaper provides a series of detailed performance testing results achieved with the Arista 7050X, 7250X and 7300 Series that reduces the need for customers and partners to dedicate their own testing time to validating the performance of these Arista Networks switches.
