Sales Pitch

Cisco Unified Computing System is a cohesive integrated computing system that unifies computing, storage access ,virtualization and the network all of this which Streamlines data center resources to reduce total cost of ownership Scales service delivery to increase business agility Radically reduces the number of devices requiring setup, management, power, cooling, and cabling

Wire once for bandwidth, not connectivity

All links can be active all the time

10 GE 10 GE has enough bandwidth Merging example2 x 1 GE Ethernet NIC 1 x 4 Gbps FC (really 3.2 Gbps) Total 5.2 Gbps over a 10 Gbps link

Most CNAs are dual-ported for HA20 Gbps usable bandwidth per server with a single CNA
