Two Management Models for Unified Fabrics

NX-OS and DCNM

Single teamIntegrated rolesAnyone does anything

Role-Based Access Control (RBAC), Virtual Device Contexts (VDCs) are key

Separate teamsSeparate rolesWell-defined hand-offs

Run all the storage traffic that you can on it

If you like it then you ought to put a SAN on it”
