Figure 7. Type 3: Medium Distributed Core Fabric Design

Use the Type 3: Medium Distributed Core design when:

• You require a fabric interlink (fabric links) bandwidth between the spines and leaves at a 40 Gb 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 (S6000 spine) for the Type 3: Medium Distributed Core design has the following:

• Six hundred and forty Gigabit of interlink (fabric links) 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 (fabric links) maximum capacity to the spine (4x 40 Gig)

• Forty–eight 10 Gig Ethernet ports for WAN connectivity

Type 4: Small Distributed Core Fabric

Use the Type 4: Small Distributed Core design when:

• You require a fabric interlink (fabric links) bandwidth between the spines and leaves of 10 Gb.

• The current and future planned uplinks and downlinks on the leaves for your core is less than or equal to 960 ports.

• The maximum port count for a Type 4: Small Distributed Core fabric with an OS ratio of 3:1 is 768. For an OS ratio of

5:1, the maximum port count is 896.

• The leaves act as a switch or ToR-leaf switch. Within the ToR, the downlink protocol can be either VLAN or VLAN

and LAG.
