Clos Concepts: L2 Clos network with Brocade VDX © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. 6 L2 Links SPINE LEAF • Manage all fabric switches as a single logical device • No blocking links and no need for Spanning Tree • Multipathing at layers 1 to 3 • Zero-touch provisioning & Self-forming trunks TRILL-based Ethernet fabric
- 7. Clos Concepts: L3 Clos network with Brocade VDX © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. 7 L3 Links SPINE LEAF • Zero-touch provisioning and deployment mechanisms (standards based) ‒ DHCP and TFTP • Management through Netconf/REST and DevOps integration • Layer 2 Extension mechanisms through native VXLAN support IP Routing protocols like BGP and OSPF
- 8. Choices for datacenter infrastructure © 2015 BROCADE COMMUNICATIONS SYSTEMS, INC. 8 L3 Clos • Smaller team to manage the infrastructure • Embedded automation required for OpEx savings • Larger team to manage the infrastructure • Tool chains in place for automation and orchestration • Network infrastructure scalable to very large deployments L2 Clos with Brocade VCS L3 Clos with Brocade VDX Both VCS and L3 Clos deployments use the same VDX hardware and Brocade NOS software!
