Dell EMC PowerScale scale-out NAS nodes use InfiniBand switches as the private network for the back-end, This white paper provides a demonstration of the Dell networking Layer 3 leaf-spine requirement using OS10 EE release 10. It was originally implemented in data centers to overcome the limitations of the three-tier architecture, where we have more east-west traffic than north-south traffic flow. The solution in this document describes a leaf-spine back-end network architecture with Dell EMC switches and a PowerScale cluster which can scale up to 252 nodes. At a high level, the Layer 2 Leaf Spine (L2LS) is a 2-Tier topology comprised of spine and leaf switches. Figure 7.

At a high level the Layer 3 Leaf Spine (L3LS) is simply a collapsed 2-Tier topology comprised of spine and leaf switches. This document provides multiple examples for deploying the architecture. This simple design, when The spine and leaf architecture describes the way in which the switches are interconnected. S5232 switch as leaf and spine Z9100 switch as leaf and spine Z9264 switch as leaf and spine Z9264 switch as spine and Z9100 or S5232 as leaf The information presented is only for one side of the back-end network. Figure 2. It is primarily a physical layer architecture. Dell Technologies recommends using a leaf-spine network in the data center with leaf switches configured as VLT peers. 44 with switches model (S5248F-ON & Z9264F-ON), CLI command, validation, and the provides use case examples in BGP and OSPF protocols Mar 26, 2015 · However these problems can be solved by taking a leaf and spine architecture approach. Feb 21, 2021 · This document provides examples for using Dell EMC Networking switches at both the leaf and spine layers and examples with Cisco Nexus switches at the spine layer. The distinguishing feature, compared to the more traditional tiered model, is that every spine switch has a physical connection to every leaf switch. A spine-leaf architecture helps data center networks reduce network latency and hop count and improve network efficiency. e. 2. The primary reason for this is cable reach, where many hosts are located across floors or across buildings; however, due to the high pricing of fiber cables and the limitations of cable distances, it is not ideal in some situations to build a full-mesh two tier Clos fabric. Leaf and spine architecture, also known as Clos architecture, is a network design approach that eliminates bottlenecks and enhances data center scalability. Spine and Leaf Architecture is a two-layer, full-mesh topology composed of a leaf layer and a spine layer, with the leaf and spine switches. Leaf spine network deployments can have a minimum of two leaf switches and one spine switch. A leaf spine network architecture is highly scalable and redundant.
