Type 3: Medium Distributed Core Fabric
With a Type 3: Medium Distributed Core design, the Z9000 spines connect to the S4810 leaves at a fixed 40 GbE line rate
as shown in the following figure. The maximum number of leaves is based on the maximum number of ports on the spine,
32 ports for the Z9000. The maximum number of spines is 16 and the maximum number of leaves is 32, as shown in the
following illustration. This illustration shows a networking system architecture in a data center are a distributed core
fabric containing a set of ToRs to which servers, storage devices, and network appliances (such as load balancers or
network security appliances) are connected. You can run application services, network services, and network security
services either on physical machines or virtual machines.
Figure 6. Type 3: Medium Distributed Core Fabric Design
Use the Type 3: Medium Distributed Core design when:
• You require a fabric interlink bandwidth between the spines and leaves at a 40 GbE line rate.
• The current and future planned uplinks and downlinks on the leaves for your distributed core fabric is less than
or equal to 1536 ports.
• The leaves act as a switch or ToR-leaf switch. Within the ToR, the protocol can be either VLAN or VLAN and
LAG.
Each Z9000 spine for the Type 3: Medium Distributed Core design has the following:
• Six hundred and forty Gigabit of interlink maximum capacity to the spine (16 x 40 Gig)
• Six hundred and forty 10 Gig Ethernet ports for WAN connectivity
Each S4810 leaf for the Type 3: Medium Distributed Core design has the following:
• One hundred and sixty Gigabit of interlink maximum capacity to the spine (4x 40 Gig)
• Forty–eight 10 Gig Ethernet ports for WAN connectivity
