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
© 2010 Brocade Communications Systems, Inc. 16
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
