Network layer The VxBlock System 1000 network layer consists of switches responsible for management, routing, and storage communication. The following figure shows the high level architecture of the VxBlock System 1000 with layer 3 uplinks and OSPF: Child TopicsData network routing topologyThe VxBlock System 1000 supports a Layer 3 routing protocol-based uplink topology or a Layer 2 uplink topology. Management network layerThe management network layer of the VxBlock System 1000 includes at least one pair of Cisco Nexus 31108TC-V Management Switches. Data plane network layer The data plane network layer carries all production network traffic that flows through the VxBlock System 1000. Storage network layerTwo Cisco MDS switches or directors make up separate fabrics to provide connectivity between the compute and storage layer. Cisco MDS 9148S Multilayer Fabric Switch The Cisco MDS 9148S Multilayer Fabric Switch provides 12 to 48 line-rate ports for nonblocking, 16 Gbps throughput. Cisco MDS 9148T Multilayer Fabric Switch The Cisco MDS 9148T Multilayer Fabric Switch provides 24 to 48 line-rate ports for nonblocking, 32 Gbps throughput. Cisco MDS 9396S 16G Multilayer Fabric Switch The Cisco MDS 9396S 16G Multilayer Fabric Switches provide 48 to 96 line-rate ports for nonblocking, 16 Gbps throughput. Cisco MDS 9396T 32G Multilayer Fabric Switch The Cisco MDS 9396T 32G Multilayer Fabric Switches provide 48 to 96 line-rate ports for nonblocking, 16 Gbps throughput. Cisco MDS 9706 and 9710 Multilayer DirectorsCisco MDS 9706 and 9710 Multilayer Directors are modular directors that provide greater scalability than the fixed SAN switches.
