Description: Arista 7050QX-32S - Switch - L3 - managed - 32 x 40 Gigabit QSFP+ + 4 x SFP+ - rack-mountable
Mfr Part #: JH579A
The Arista 7050QX-32S is a purpose built compact and energy efficient data center switch 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. It 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 switch delivers feature rich speed performance with an overall throughput of 2.56 Tbps. For configuration flexibility it supports up to 32x 40GbE ports. The Arista 7050QX-32S offers low latency from 550ns in cut-through mode, and a shared 12 MB 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 switch provides impressive power efficiency.

- LANZ for microburst detection
- DANZ Advanced Mirroring & Tap Aggregation for improved visibility
- Self-configure and recover from USB
- Toolless rails for simple installation
- Leverage Linux tools with no limitations
- Dynamic buffer allocation
In cut-through mode, the Arista 7050QX-32S switch forwards 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 MBytes. Unlike other architectures that have fixed per-port packet memory, the Arista 7050QX-32S uses Dynamic Buffer Allocation (DBA) to allocate up to 6.7MB of packet memory to a single port for lossless forwarding.
- Scaling data center performance
The Arista 7050QX-32S delivers line rate switching at layer 2 and layer 3 to enable faster and simpler network designs for data centers that dramatically lowers the network capital and operational expenses. 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 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 far as 64-way without significant changes to the architecture. The Arista 7050QX-32S includes enhancements that allow for flexible scale-out designs: 64-way ECMP and 64-way MLAG to provide scalable designs and balance traffic evenly across large scale 2 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.
- Enhanced features for high performance networks
The Arista 7050QX-32S 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.
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN. Offering a wire-speed gateway between VXLAN and traditional L2/3 environments, the 7050QX-32S 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 switches 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 7050QX-32S 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 pre-defined configuration profiles available on the 7050QX-32S ensures optimal resource allocation for all network topologies and network virtualization technologies.
