Building Next Generation Data Center
Networks
Some Key Design Considerations
Performance & Scalability
•Linear Scale to meet growing elasticity
demands of today’s virtualized Data Center
environments
•Multiple Layer 3 Gateways for optimal Layer 3
forwarding with for HA, Resiliency and Network
Scaling
•Multiple Layer 2 Paths with Active-Active
capability to support growing east-west
bandwidth
•Efficient Load Balancing on LAG channel
member links for perfect load distribution
•Low Latency (Fewer hops) for predictable and
better Application Performance

Scaling Virtual Server Environments
Technical Challenges Today
Layer 2: only 1 active path
STP disables other paths
40% of Links Not Used
Increase utilization using MSTP
(spanning tree per VLAN)
Increases complexity
Creates multiple single-path networks; limits
sphere of mobility
Poor application response during
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

TRILL-Based Networking
Transparent Interconnection of Lots of Links
Layer 2: multiple active paths
• TRILL calculates multiple routes
100% of links used
ECMP handles even distribution
• ASIC-level frame-based load balancing
Link failure
• Within a trunk triggers no reconvergence
• Total path failure has very quick recovery
TOR Layer 3 complexity NOT needed
• Simple flat Layer 2 networks
• Fast low-latency switching in hardware

Ethernet Fabrics
A New Network Architecture
• Classic architectures often require three tiers
in the physical network
• STP disables links in the fabric to prevent
loops, limiting network utilization
• Each switch has to be managed individually
© 2010 Brocade Communications Systems, Inc.
• Fabric architectures flatten and seamlessly
scale out the Layer 2 network at the edge
• All links in the VCS fabric are active and it is
managed as one
• Switches in the VCS fabric are managed at one

What is Network Virtualization?
A framework for overlaying virtualized Layer 2
networks over Layer 3 networks
Why Do Network Virtualization?
• Network isolation for security, multi-tenancy
• Deliver workload-specific network services
• Better VM mobility, virtual asset utilization
