Overview:

The Arista 7050 series 1/10GBase-T switches offer wire speed layer 2/3/4 performance with a choice of 36, 52 or 64 ports of 10GbE in a compact 1RU chassis. The Arista 7050T switches include 32 and 48 port models with auto-negotiating 100Mb/1Gb/10GBase-T ports with standard RJ45 interfaces and a choice of either 4 40GbE QSFP+ interfaces or 4 10GbE SFP+ ports. The QSFP+ interfaces can operate as either a 40GbE port or as four independent 10GbE ports to provide a total of 64 10GbE ports in the 7050T-64 model. Positioned for data center server access and high performance workstations the 7050T switches offer backwards compatibility with existing standard Gigabit Ethernet cabling and investment protection for migration to 10 Gigabit Ethernet keeping costs down while offering an easy evolution.

The Arista 7050T switches offers flexible support for triple speed 100Mb, 1Gb and 10Gb Ethernet together with a shared 9 MB packet buffer pool that is allocated dynamically to ports that are congested. With a typical power consumption of less than 6 watts/port the 7050T Series provides industry leading power efficiency for the data center. An optional built-in SSD supports advanced logging, data captures and other enhanced services directly on the switch.

Arista EOS

The Arista 7050T 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

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

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)

1000Base-T and 10GBase-T Cabling Distances

* Performance of 10GBASE-T over Cat5e cabling is not specified in the standard. Actual performance is based on loss characteristics of cabling and panels.

Dynamic Buffer Allocation

In cut-through mode, the Arista 7050 10GBase-T switches forward packets with a low latency of under 3 microseconds. 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).
