.
The convergence of Ethernet and Fibre Channel with FCoE provides the same level of connectivity as
previous technologies, but requires the following:
50% fewer switches in each server rack—Only two FCoE ToR switches, compared with four (two
network and two Fibre Channel) switches per rack
50% fewer adapters per server
75% fewer cable connections
Less power consumption
For more information about FCoE switches, see:
"B-series switches and fabric
"C-series Fibre Channel and FCoE switches and fabric
For more information about configuring FCoE SANs, see the HP StorageWorks Fibre Channel Over
Ethernet Application Note, available at http://www.hp.com/go/sdgmanuals.

Data availability

SAN data availability depends on the reliability of the SAN fabric, servers, and storage systems
during routine operations. The data availability level required for your SAN environment is based on:
Administrative requirements (for example, backup schedules, operating procedures, and staffing)
Protection level for applications or data
