Description

The Arista DCS-7050SX2-72Q-F is a high-performance 1RU data center switch delivering 48x 10GbE SFP+ ports and 6x 40GbE QSFP+ uplinks with 1.44Tbps switching capacity and ultra-low 550ns latency. Powered by Arista EOS, it provides wire-speed Layer 2 and Layer 3 forwarding with advanced features including VXLAN routing, 128-way ECMP, 64-way MLAG, and dynamic buffer allocation. Ideal for cloud data centers, high-performance computing, and enterprise leaf-spine architectures requiring scalable, low-latency connectivity.

Features

Wire-speed Layer 2 and Layer 3 forwarding with non-blocking architecture
- 128-way ECMP (Equal-Cost Multi-Path) routing for scalable leaf-spine designs
- 64-way MLAG (Multi-Chassis Link Aggregation) for redundancy and load balancing
- VXLAN routing, bridging, and gateway support for network virtualization
- Dynamic Buffer Allocation (DBA) with 16MB shared packet memory
- Advanced QoS with 8 hardware queues per port, traffic classification, marking, and shaping
- Comprehensive Layer 2 protocols: STP, RSTP, MSTP, RPVST+, and LACP
- IPv4 and IPv6 unicast and multicast routing support
- MACsec (802.1AE) encryption for secure Layer 2 communication
- Access Control Lists (ACLs) for Layer 2 to Layer 4 traffic filtering
- Arista Latency Analyzer (LANZ) for real-time micro-burst congestion monitoring
- sFlow and DANZ (Data ANalyZer) for deep packet inspection and network visibility
- Zero-Touch Provisioning (ZTP) for automated deployment and configuration
- Hot-swappable dual redundant power supplies and N+1 fan redundancy
- OpenFlow, DirectFlow, and eAPI support for Software Defined Networking (SDN)
- VM Tracer integration for VMware vSphere environments
- IEEE 1588 PTP (Precision Time Protocol) for time synchronization
- Jumbo frames support up to 9216 bytes
- 4096 VLANs and Q-in-Q (802.1Q tunneling) support

FAQs

Q: Can the 40GbE QSFP+ ports be used as 10GbE connections?
A: Yes, each of the 6 QSFP+ ports can be configured as four independent 10GbE ports using breakout cables, providing up to 72 total 10GbE ports for maximum flexibility in network design.

Q: What Layer 3 routing protocols are supported?
A: The DCS-7050SX2-72Q-F supports comprehensive Layer 3 routing protocols including OSPF, OSPFv3, BGP, MP-BGP, IS-IS, and RIPv2, along with VRF for network segmentation and up to 128-way ECMP for load balancing.

Q: Does this switch support network virtualization technologies?
A: Yes, the switch provides hardware-accelerated VXLAN routing, bridging, and gateway functionality, enabling seamless integration between VXLAN and traditional Layer 2/Layer 3 environments for modern cloud and virtualized data center deployments.

Q: What is the typical power consumption per port?
A: The switch has typical power consumption of less than 2 watts per 10GbE port, making it highly energy-efficient for high-density data center deployments. Total system power consumption is approximately 280W depending on configuration.

Q: Is the switch suitable for high-frequency trading or latency-sensitive applications?
A: Yes, with ultra-low latency of 550 nanoseconds in cut-through mode and wire-speed forwarding capabilities, the DCS-7050SX2-72Q-F is ideally suited for latency-sensitive applications such as financial trading, high-performance computing, and real-time analytics.
