Overview:

The Arista 7050 series 10/40G switches offer wire speed layer 2/3/4 performance with 52 or 64 ports of 10GbE in a compact 1RU chassis. The 7050S-64 switch offers 48 SFP+ and 4 QSFP+ interfaces while the 7050S-52 switch offers 52 SFP+ interfaces. Each QSFP+ 40GbE port can also operate as four independent 10GbE ports to provide a total of 64 10GbE ports in the 7050S-64 model. The Arista 7050S offers a latency of 800 to 1200 ns in cut-through mode, and a shared 9 MB packet buffer pool that is allocated dynamically to ports that are congested. With a typical power consumption of less than 2 watts/port with twinax copper cables, and less than 3 watts/port with SFP/QSFP lasers, the 7050S 10Gb switches provide industry leading power efficiency for the data center. An optional built-in SSD supports advanced logging, data captures and other services directly on the switch.

Arista EOS

The Arista 7050S switches run the same Arista EOS software as all Arista products, simplifying network administration. With Arista EOS, advanced monitoring and automation capabilities such as Zero Touch Provisioning, VM Tracer and Linux based tools can be run natively on the switch.

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. Several Linux based tools can be run directly on the switch, running on a powerful dual-core x86 CPU subsystem.

Benefits:

High Availability

Arista 7050S-64 Rear View: Front-to-rear airfow model, Arista 7050S-64 Rear View: Rear-to-front airfow model

The Arista 7050 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 PSU’s and fans - common to Arista 1RU devices
Live software patching
Self healing software with Stateful Fault Repair (SFR)
Up to 16 10GbE ports per link aggregation group (LAG)
Multi-chassis LAG for active/active L2 multipathing
32-way ECMP routing for load balancing and redundancy

Dynamic Buffer Allocation

Arista 7050S: Latency through SFP+ ports

In cut-through mode, the Arista 7050 10Gb switches forward packets with a latency of 800 to 1350 nanoseconds. Upon congestion, the packets are buffered in shared packet memory that has a total size of 9 MBytes. Unlike other architectures that have fixed per-port packet memory, the 7050 switches use Dynamic Buffer Allocation (DBA) to allocate up to 5MB of packet memory to a single port for lossless forwarding.

Provisioning Tools and Built-in Storage

The 7050 series switches offer advanced capabilities for network provisioning. With ZTP, the switch can be automatically provisioned through a centralized management system with a dynamically generated configuration and preferred boot image. A built-in 50GB SSD is available as an option from the factory. The integrated storage allows for a whole new family of applications that can be run from the network itself. This includes having the switch be a PXE boot server, store syslogs for audit and compliance right on the switch, capturing and saving data packets via tcpdump and Linux based services such as DHCP and Precision Time Protocol (PTP).
