Overview:
The Arista 7150S series represents the industry's leading ultra low latency 1RU 1/10/40GbE layer 2/3/4 wire speed switch family, offering a unique combination of performance, advanced functionality and extensive onboard resources.
Designed to suit the requirements of demanding environments such as ultra low latency financial ECNs, HPC clusters and cloud data centers, the class-leading deterministic latency from 350ns is coupled with a set of advanced tools for monitoring and controlling mission critical environments.
| Feature | Benefits |
|---|---|
| Wire-speed Low Latency Network Address Translation | Reduce NAT latency by 10s of microseconds vs traditional high latency solutions |
| IEEE 1588 Precision Time Protocol (Boundary and Transparent modes) | Provides hardware-based timing for accurate inband time distribution with nanosecond accuracy |
| Integrated High Precision Oscillator | Ensures highly accurate timing with extended holdover |
| Latency and Application Analysis LANZ | Detect, capture, stream microbursts and transient congestion at microsecond rates |
| Advanced Multi-port Mirroring Suite | Avoid costly SPAN/TAP aggregators with in-switch capturing, filtering and time-stamping |
| Wire-speed VXLAN Gateway | Enabling next generation Data Center virtualization |
| AgilePorts | Adapt from 10G to 40G without costly upgrades |
Arista EOS
The Arista 7150S 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, VMTracer and Linux based tools can be run natively on the switch with the powerful dual-core x86 CPU subsystem.

Benefits:
Deterministic, Ultra Low Latency
The Arista 7150S is optimized for ultra low latency, cut-through forwarding. It offers the same low latency characteristics at all packet sizes. The latency remains consistent even when features such as L3, ACL, QoS, Multicast, Port Mirroring, LANZ+ and Time-Stamping are enabled. The 7150S also supports cut-through mode at 100Mb and 1GbE speeds at low latency for legacy connections.
Dynamic Buffer Allocation
The Arista 7150S forwards packets at an ultra low latency of 350 nanoseconds from any port to any other port. However when a microburst or transient in-cast condition causes contention of an egress interface, packets must be buffered. The 7150S’ global packet memory is dynamically allocated on demand to congested interfaces, avoiding packet loss.
Enhanced Features for High Performance Networks
The Arista 7150S delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high performance environments, with solutions for network address translation, precise timing and next-generation virtualization.
Low-Latency Address Translation
The Arista 7150S includes support for line rate NAT while still delivering latency of under 1 microsecond. Latency and performance sensitive environments can take advantage of NAT to resolve addressing challenges such as masking internal addresses and translating overlapping ranges to avoid conflicts without penalty.
Monitoring, Analysis and Forensics
Arista’s enhanced LANZ microburst and latency analysis enables the monitor of even the slightest transient congestion at microsecond granularity. Data affected by congestion is captured and verbose logs are written locally and streamed in real time to external tools over an open protocol buffer encoded format. Event Monitoring complements LANZ with protocol-layer captures, providing a forensic history of network adds, moves and changes. The combination of Arista’s Advanced Mirroring Suite and the ability to time-stamp every packet in hardware with features such as sFlow, delivers unmatched instrumentation of network behavior and performance. Optimized to support pro-active capacity planning and pre-empt issues, the 7150 is uniquely equipped to root-cause network anomalies.
Precision Timing (IEEE 1588)
Arista’s hardware derived Precision Time Protocol solution provides a robust mechanism for accurate in-band time distribution in high performance environments. Offering both Boundary and Transparent Clock modes, the versatile 7150S enables timing networks to scale independently of Grand Master capacity, maintaining accuracy approaching that of a dedicated out-of-band platform. Uniquely, the 7150S employs a High Precision Oscillator for consistent timekeeping. With disciplined stability measured in single-digit picoseconds and 24 hr holdover of single-digit nanoseconds, the optional clock module ensures exceptional determinism in timing operations.
Virtualization
Supporting next-generation virtualized data centers requires tight integration with orchestration tools and emerging encapsulation technologies such as VXLAN and NVGRE. The 7150S builds on the valuable tools already provided by the Arista VMTracer suite to integrate directly into encapsulated environments. Offering a true, wire-speed, low latency gateway between VXLAN and traditional L2/3 environments, the 7150S 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.
AgilePorts Enable Flexible Deployment
AgilePorts deliver complete flexibility in connectivity - each SFP+ interface is capable of supporting 100M-10G over a variety of media, including DWDM with distances up to 80km. The AgilePorts feature also enables groups of adjacent SFP+ ports to be configured for 40Gb operation using 10Gb transceivers and cables providing maximum port flexibility and a seamless migration from 10Gb to 40Gb.
High Availability
The Arista 7150S switches were designed for high availability and simple provisioning from both a software and hardware perspective. Key high availability features include:
- 1+1 hot-swap power supplies and four N+1 hot-swap fans
- Color coded PSUs and fans - common to Arista 1RU devices
- EOS Zero Touch Provisioning (ZTP)
- Self healing software with Stateful Fault Repair (SFR)
- Live software patching
- 32-way MLAG and ECMP routing for all-active L2 and L3
