7170 Series | Use Cases

Intelligent Packet Buffers

The Arista 7170 Series switches offer up to 22 MB of unified packet buffer that is shared dynamically across all ports. The packet buffer

can be allocated programmatically across multiple classes of applications to optimize performance for custom applications along with

standard data center applications designed to avoid congestion from micro-bursts or fan-in packets. Unlike architectures with small per-

port packet memory, or small shared memory pools the 7170 Series use a scheme to allocate memory intelligently based on a

combination of traffic class, queue depth and quality of service policy ensuring fair allocation to all ports. Buffer utilization, occupancy

and thresholds are all visible with Arista LANZ and can be exported to monitoring tools for detailed analysis.

Software Defined Cloud Networks

Arista Software Defined Cloud Networking (SDCN), combines the principles that have made cloud computing the unstoppable force

that it is: automation, self service provisioning, and linear scaling of both performance and economics coupled with the trend in

Software Defined Networking that delivers: network virtualization, custom programmability, simplified architectures, and lower capital

expenditure. This combination creates a best-in-class software foundation for maximizing the value of the network to both the

enterprise and service provider data center. A new architecture for the most mission-critical location within the IT infrastructure that

simplifies management and provisioning, speeds up service delivery, lowers costs and creates opportunities for competitive

differentiation, while putting control and visibility back in the hands of the network and systems administrators.

Smart System Upgrade

Smart System Upgrade is a network application designed to address one of the most complicated and challenging tasks facing data

center administrators - network infrastructure maintenance. Changes to the underlying network infrastructure can affect large numbers

of devices and cause significant outages. SSU provides a fully customizable suite of features that tightly couples data center

infrastructure to technology partners allowing for intelligent insertion and removal, programmable updates to software releases and

open integration with application and infrastructure elements.

CloudVision

CloudVision is a network-wide approach for workload orchestration and workflow automation as a turnkey solution for Cloud

Networking. CloudVision extends the EOS publish subscribe architectural approach across the network for state, topology, monitoring

and visibility. This enables enterprises to move to cloud-class automation without needing any significant internal development.

Advanced Event Management (AEM)

Advanced Event Management (AEM), a sub-system of Arista EOS, is a powerful and flexible tool to automate tasks and customize the

behavior of EOS and the operation of the overall data center switching infrastructure. Simplifying the overall operations, AEM provides

the tools to customize alerts and actions. AEM allows operators to fully utilize the intelligence within EOS to respond to real-time events,

automate routine tasks, and automate actions based on changing network conditions.

AlgoMatch TM

AlgoMatch is a unique Arista innovation for modern cloud networks, combining both software and hardware to enable more flexible

and scalable solutions for access control, policy based forwarding and network telemetry. By combining general purpose memory with

with advanced software algorithms AlgoMatch delivers higher scale, performance and efficiency with lower power and is more cost

effective than traditional solutions. AlgoMatch provides a more efficient packet matching algorithm that in turn enables flow matching

for access control, policy and visibility. The net benefits are a high performance policy engine with both increased functionality and

scale in a cost and power efficient solution.

•

AlgoMatch enables IPv4 and IPv6 access control at the same scale

•

L4 rule ranges are programmed efficiently without expansion or reduced capacity

•

Multiple actions can be performed on a single packet or flow

•

User defined filters allow flexible packet classification based on offsets for custom actions

•

Supports rich policy with consistent semantics that would exhaust classical resources

* Not currently supported in EOS
