Why can’t we get there ?
12/2/2010© 2010 Brocade Communications Systems, Inc. Company Proprietary Information 35
Challenges of Current Data Center Networks
• Layer 2 performance, scalability, reliability• Limitations of Spanning Tree Protocol (STP)
• Scaling virtual server environments
• Virtual machine mobility• Must run in Layer 2; IP address stays the
same• Enforce the same policies and permissions
• Infrastructure complexity• Lots of switches to manage• Layer 3 protocols to the edge
• Management overhead• High operational costs
Must Be Solved for Virtualized Data Centers
Challenges
12/2/2010© 2010 Brocade Communications Systems, Inc. Company Proprietary Information 36
Scaling Virtual Server EnvironmentsChallenges Today
Layer 2: Only one active path
• STP disables other paths
• Not “virtualization-optimized”
Add virtual machines
• Add 1 GbE connections
• Move to 10 GbE for simplicity and higher performance
• Uplinks are stressed; need more 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
12/2/2010© 2010 Brocade Communications Systems, Inc. Company Proprietary Information 37
Cumbersome Virtual Machine MobilityChallenges Today
Limited sphere of mobility
• STP limits flexibility to a minimized, defined tree of switches
• Layer 3 limits mobility to a single rack
VM migration can break network/application access
• Port setting information must be identical at destination
Map services (VLANs, QoS, security) to all physical ports
• Eases mobility but undermines network and security best practices
Distributed Virtual Switch
• Addresses configuration needs but consumes server resources and is still restricted by physical limits
Limited insight into where VMs are running
• VMs exist anywhere in the cluster

Today: Before Unified I/OToday:
Parallel SAN and LAN Potentially less optimal use of
networks Four or more connections per server:
– Higher adapter and cabling costs– Adds cap-ex and op-ex– Each connection adds potential points
of failure in the fabric
Slower server provisioning Additional redundancy due to
separate physical infrastructures Separate management realms Ethernet

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 carry both IP and storage traffic, without compromise
