12. Target Applications
Building 1: High Availability (HA) Top-of-Rack
• For midsize server installations, two half-width M4300
10GbE models can be paired in a single rack space for
redundant top-of-rack
• Management unit hitless failover and nonstop forwarding
ensure no single point of failure for servers and storage
Building 2: Edge Ring Stack
• Common for intermediate distribution frames (IDF) in
K-12, stacking topologies simplify deployments at the edge
• Management unit hitless failover and nonstop forwarding
ensures continuous uptime for clients across the stack
Building 3: Spine and Leaf Stack
• For typical collapsed core installations, with a variety
of 1G and 10G access ports in branch offices, server
rooms
• Spine and leaf architectures deliver highest performance
with every leaf switch (1G) connecting to every spine
switch (10G) for a fully non-blocking deployment
• With management unit hitless failover and nonstop
forwarding, leaf switches keep forwarding L2 and L3 traffic
in and out, while backup spine unit guarantees connectivity
to the core

14. What is Spine and Leaf?
Traditional 3 Tier Model = Spanning Tree Based
Network
Spine-Leaf Based Network = Non-Blocking
Links for More Optimal Traffic
Core
Distribution
Access
Access = Leaf switches
Core / Aggregation = Spine switches
- In 3 Tier model, many links are in “blocked” mode due to STP, hence East West traffic at the access – predominant in DC – is slower
- In Spine/Leaf model, all links are active for optimal traffic in ultimately line-rate topologies
- In Spine/Leaf model, >2x increase in network availability
