This partnership will provide our customers with proven networking solutions that are superior to legacy alternatives and that complement HPE compute, storage, virtualization, and cloud offerings.  

The Arista 7050QX switches are members of the Arista 7050X Series and key components of the Arista portfolio of data center switches. Arista 7050X Series switches are purpose built 10/40GbE data center switches in compact and energy efficient form factors with wire speed Layer 2 and Layer 3 features, combined with advanced features for software-defined cloud networking. 

Increased adoption of 10 gigabit Ethernet servers, coupled with applications using higher bandwidth, is accelerating the need for dense 10- and 40-gigabit Ethernet switching. The 7050QX Series supports a flexible combination of 10G and 40G in a highly compact form factor that allows customers to design large leaf and spine networks to accommodate east-west traffic patterns found in modern data centers, high performance compute, and Big Data environments. 

Featuring 32 QSFP+ ports in a 1RU form factor, the switches deliver feature-rich Layer 2 and Layer 3 wire speed performance, with an overall throughput of 2.56 Tbps. For configuration flexibility, all models support up to 32x 40GbE ports, or 24 QSFP+ ports can be used as 4x10GbE for a 96x10GbE and 8x 40GbE system. In addition, the 7050QX-32S and 7050QX2-32S feature four SFP+ ports that are internally shared with the first QSFP+ port for directly connecting 10GbE and 1GbE interfaces. The Arista 7050QX switches offer low latency from 550ns in cut-through mode, and a shared packet buffer pool that is allocated dynamically to ports that are congested. With typical power consumption of less than 5 watts per 40GbE port, the 7050QX Series provides industry leading power efficiency. An optional built-in SSD supports advanced logging, data captures, and other services directly on the switch.

Combined with Arista EOS, the 7050QX Series delivers advanced features for Big Data, cloud, and virtualized and traditional designs.

Arista EOS

The Arista 7050X runs the same Arista EOS software as all Arista products, simplifying network administration. Arista EOS is a modular switch operating system with a unique state sharing architecture that cleanly separates switch state from protocol processing and application logic. Built on top of a standard Linux® kernel, all EOS processes run in their own protected memory space and exchange state through an in-memory database. This multi-process state sharing architecture provides the foundation for in-service software updates and self-healing resiliency.

With Arista EOS, advanced monitoring and automation capabilities such as zero touch provisioning, VM Tracer, and Linux based tools can run natively on the switch with the powerful x86 CPU subsystem..

High Availability

The Arista 7050X Series switches were designed for high availability from both a software and hardware perspective. Key high-availability features include:

• 1+1 hot-swappable power supplies and four N+1 hot-swap fans
• Color coded PSUs and fans
• Live software patching
• Self-healing software with stateful fault repair (SFR)
• Smart System Upgrade (SSU) and Accelerated Software Update (ASU)
• Up to 64 10GbE or 40GbE ports per link aggregation group (LAG)
• Multi-chassis LAG for active/active L2 multi-pathing
• Up to 128-way ECMP routing for load balancing and redundancy

Dynamic buffer allocation

In cut-through mode, the Arista 7050QX switches forward packets with a latency of 550 nanoseconds to 650 nanoseconds. Upon congestion, the packets are buffered in shared packet memory that has a total size of 12 MB. Unlike other architectures that have fixed per-port packet memory, the 7050QX Series switches use dynamic buffer allocation (DBA) to allocate up to 6.7 MB of packet memory to a single port for lossless forwarding. The 7050QX2-32S has an optimized 16 MB buffer for more demanding environments.

Scaling data center performance

The Arista 7050QX Series delivers line rate switching at Layer 2 and Layer 3 to enable faster and simpler network designs for data centers, which dramatically lowers network capital and operational expenses. When used in conjunction with the Arista 7000 Series of fixed and modular switches, it allows networks to scale to over 110,000 10G servers in low‑latency two‑tier networks that provide predictable and consistent application performance. The flexibility of the L2 and L3 multi-path design options, combined with support for open standards, provides maximum flexibility, scalability, and network-wide virtualization. Arista EOS advanced features provide control and visibility with a single point of management.

Maximum flexibility for scale-out network designs

Scale-out network designs enable solutions to start small and evolve over time. A simple two way design can grow as large as 64-way without significant changes to the architecture. The Arista 7050QX includes enhancements that allow for flexible scale-out designs:

Up to 128-way ECMP and 64-way MLAG provide scalable designs and balance traffic evenly across large-scale two-tier leaf-spine designs

Custom hash algorithms for efficient hashing, persistent hashing, and custom lookups for tunneled protocols.

Flexible allocation of L2 and L3 forwarding table resources for more design choice

Wide choice of dense 10G/40G ports for single-port multi-speed flexibility

VXLAN routing, bridging, and gateway for physical-to-virtualization communication to enable next-generation data center designs

DANZ, sFlow, and multi-port mirroring to detect micro-burst congestion and provide network wide visibility and monitoring 

Software-defined networking

Arista Software Defined Cloud Networking (SDCN) combines the principles that have made cloud computing the unstoppable force that it is-automation, self-service provisioning, and linear scaling of both performance and economics-with the trend in software defined networking that delivers: network virtualization, custom programmability, simplified architectures, and lower CAPEX. This combination creates a proven software foundation for raising the value of the network for both the enterprise and service provider data center. This new architecture for the most mission-critical location within the IT infrastructure simplifies management and provisioning, speeds up service delivery, lowers costs, and creates opportunities for competitive differentiation, while putting control and visibility back in the hands of the network and systems administrators. 

Smart System Upgrade

Smart System Upgrade is a network application designed to address one of the most complicated and challenging tasks facing data center administrators: network infrastructure maintenance. Changes to the underlying network infrastructure can affect large numbers of devices and cause significant outages. SSU provides a fully customizable suite of features that tightly couples data center infrastructure to technology partners, allowing for intelligent insertion and removal, programmable updates to software releases, and open integration with application and infrastructure elements. 

Advanced Event Management (AEM)

Simplifying the overall operations, AEM provides the tools to customize alerts and actions. AEM is a powerful and flexible set of tools to automate tasks and customize the behavior of EOS and the operation of the overall data center switching infrastructure. AEM allows operators to fully utilize the intelligence within EOS to respond to real-time events, automate routine tasks, and automate actions based on changing network conditions.

Enhanced features for high-performance networks

The Arista 7050QX delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high-performance environments, with solutions for data monitoring and next-generation virtualization.

Precise data analysis

Arista Latency Analyzer (LANZ) is an integrated feature of EOS. LANZ provides precise real‑time monitoring of micro-burst and congestion events before they impact applications, with the ability to identify the sources and capture affected traffic for analysis.

Virtualization

Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. The 7050QX builds on the valuable tools already provided by the Arista VM Tracer suite to integrate directly into encapsulated environments. Offering a wire-speed gateway between VXLAN and traditional L2/L3 environments, the 7050QX makes integration of non-VXLAN aware devices-including servers, firewalls, and load-balancers-seamless and provides the ability to leverage VXLAN as a standards-based L2 extension technology for non-MPLS environments.

Unified forwarding table

Cloud network scalability is directly impacted by the size of a switch’s forwarding tables. In many systems, a one-size-fits-all approach is adopted using discrete fixed-size tables for each of the common types of forwarding entry. The Arista 7050QX leverages a common unified forwarding table for the L2 MAC, L3 routing, L3 host and IP multicast forwarding entries, which can be partitioned per entry type. The ideal size of each partition varies depending on the network deployment scenario. The flexibility of the UFT, coupled with the range of predefined configuration profiles available on the 7050QX, ensures optimal resource allocation for all network topologies and network virtualization technologies.
