Major Drivers in Network Evolution

• Convergence of Traffic Types,

“D-V3-S”• deliver information to any device

on any network at any time

• On-demand availability of resources

• Manage Costs with a "pay as you grow" model

• Lower Entry Costs and TCO

• Increased / Strategic Use of Virtualization

• Bandwidth Escalation

• Superior Desktop Performance

• Ubiquitous Security

• Prevent Business Disruptions

the need to accommodate modern technical challenges

Transition to Private Cloud Architectures

• Private cloud architectures • Simplify infrastructure

• Become more agile

• Realize CapEx and OpEx savings

• Brocade fabric-based solutions lead the industry• Essential foundation for cloud-optimized

networks

• Simple, flat, and high-performance

• Highly resilient and scalable networks

• Full benefits of virtualization in private clouds

• Open and Partner centric

Scaling Virtual EnvironmentsChallenges Today

Use Layer 2 for SimplicityOnly ONE active pathSTP disables other pathsNot “virtualization optimized”

More Virtual Machines create NeedAdd more GbE connectionsUpgrade to 10 GbE Use LAG Groups

Upgrade to MSTP (STA per VLAN)Increases complexityCreates multiple single-path networks; limits sphere of mobility

Link failures expose weaknessSTP reconvergence – network is downBroadcast storms stress network

Layer 3 as an alternative? (Trade Offs)Greater complexity; higher cost

VM mobility limited to rack

FABRIC ARCHITECTURE

CLASSIC HIERARCHICAL

ETHERNET ARCHITECTURE

Brocade MLXeCiscoJuniper

• 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• Designed for Client-Server, North-South Traffic Flows

• 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 as one• VCS offers distributed intelligence throughout the fabric

• New services can be added dynamically• Best suited for the new East-West Traffic requirements

Flatter, faster, lower latency

Massive, linear scalability

• VDX is configured with vCenter access information and credentials

• VDX performs discovery of virtual infrastructure assets

• Based on discovered assets VDX will automatically configure corresponding objects:

• Port-profiles and VLAN creation

• MAC address association to port-profiles

• Port, LAGs, vLAGs are put into profile mode automatically based on ESX host connectivity

• VCS network is ready for Virtual Machine movements
