Type 1: Extra Large Distributed Core Fabric
With a Type 1: Extra Large Distributed Core fabric design, the Z9000 or S6000 spines connect to the
Z9000 or S6000 leaves at a fixed 40 GB line rate. The maximum number of leaves is based on the
maximum number of ports on the spine (for example, 32 ports for the Z9000, as shown in the following
figure).
