Data Center Deployment
The switch is designed for high-availability data center environments with a high 
40G port density and switching capacity. The switch includes redundant, hot-
swappable, load-sharing AC PSUs, and a hot-swappable multiple-fan fan trays 
where the direction of the cooling airflow can be set to either port-to-power or 
power-to-port options. Meeting the network scaling requirements of enterprise 
and cloud data centers, the switch can be deployed as a top-of-rack switch or as 
part of a distributed spine network, providing full line-rate switching at Layer 2 or 
Layer 3 across all ports.
Figure 3:  Cloud Data Center Deployment
In many data center configurations, Ethernet connections link servers and data 
networks, and Fibre Channel connections link servers to storage networks. This 
switch enables the creation of a converged network, which supersedes Fibre 
Channel and employs lossless Ethernet connections between FCOE storage, 
servers, and other data network switches.
