A hypotheticalTCO Example
1000 Servers, with 10% annual growth rate
2 1GbE LOMs & 4 1GbE NICs
2 8Gb FC HBAs per server
Access LAN max. oversubscription: 4:1
Edge SAN max. oversubscription: 4:1
Core LAN max. oversubscription: 1:1
Core SAN max. oversubscription: 1:1
5 year time frame
Cost of power: $.10 kwh
Power Use Efficiency (PUE) 2.5 (industry standard)
NICs: $200, HBAs: $740, CNAs: $750

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
