Scaling Virtual Server EnvironmentsChallenges Today

Layer 2: only 1 active path

STP disables other paths

Not “virtualization optimized”

Add Virtual Machines

Add additional GbE connections

Move to 10 GbE for simplicity and more performance

Uplinks are stressed; need more connections in LAG


connections in LAG

Increase utilization using MSTP (spanning tree per VLAN)

Increases complexity

Creates multiple single-path networks; limits sphere of mobility

Link failure

STP reconvergence – network is down

Broadcast storms stress network

Layer 3 as an alternative

Greater complexity; higher cost

VM mobility limited to rack

�

Imagine if…

• There was no requirement for STP in Layer 2 networks

• All paths in the networks were utilized with traffic automatically distributed

• Link failure did not result in a temporary outage and paths were always deterministic

• The network provided low latency, lossless transmission and could

Virtual Machine MobilityChallenges Today

Limited sphere of mobility

STP limits flexibility to a minimized, defined tree of switches

L3 limits mobility to a single rack

VM migration can break network/application access
