Agenda Cloud-driven “New IP” has taken position across Enterprise Architectures

• How we do networking across the industry is changing— The “New IP”

• Platforms for SDN underlay

• Ethernet Fabrics—The underlying platforms for New IP

• SDN technologies from hardware to orchestration

The Importance of the Intelligent Underlay

• Reliable Infrastructure

• High performance with low latency

• Convergence-ready for storage

• Elimination of manual tasks

• Application aware

Physical / Virtual Network Independence The physical foundation for virtual networks


High risk of downtime and productivity losses

Resiliency Unmatched uptime and high productivity

Automated network build-out: low

operational costs

Maximize ROI: maximize link and

port utilization

Virtual Networks

Simplicity

Efficiency Wasted capital budget: over-provisioning

Physical network complexity: high operational costs

Service Fabric (VLAN 10 VF 5010)

Transport Fabric (VLAN 10,20,30 VF 5030)

VF: Per Port, Per VLAN, Per Mac

Within VCS Fabric domain

Use Cases

• Enterprise Private Cloud: Virtual Fabric per department, Business Unit & Company

• Service Provider Public Cloud: Virtual Fabric per Customer

VCS—Evolutionary Architecture Seamless Integration with Classic Network Topology

• Intro VCS in a POD • Flat layer 2 • Co-exist with legacy access

switches

• Scale Out VCS • Co-exist with legacy access/

aggregation

• Fully deployed fabric • Core-Edge Solution • Legacy network support

VDX Auto NAS—Block Storage Feature


• All the nodes in the fabric will auto prioritize NAS Storage traffic over other traffic types (NFS, SMB/CIFS)

• Ability to monitor IP Storage traffic through ACL Counters

• Functionality:

‒ Specify the IP Address of the NAS Head

‒ All the traffic destined to and originated from NAS Head will be prioritized in the Fabric

VCS Fabrics & SDN Controller integration

• Faster, more elegant integration with in-house and third-party management and orchestration tools

– Robust REST API, fully documented YANG model, and tools for developers

– Simpler to write and maintain network applications using the fabric-level API

– DevOps integration for Puppet and Python scripting

• Efficient orchestration integration without loss of administrative control

– Fabric- and node-level programmability and troubleshooting

– Supports Brocade Vyatta SDN Controller and third-party OpenDaylight-compliant controllers through OpenFlow 1.3

• Self-tuning fabric in response to management-level changes

Ethernet Fabrics Conclusion


• A flexible “Underlay” in the Data Center that can transport any I/O & optimized for SDN technologies is critical for ensuring scalability and viability

• The new Cloud optimized Data Center will require less manual configuration and simpler architectures to reduce costs, stream-line provisioning, change management, and enable application efficiencies

• Brocade VCS Ethernet Fabrics Transform the Data Center allowing Integrators and Providers to Leverage the Benefits of New IP Technologies
