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 rules ” on page 93
• “ C-series Fibre Channel and FCoE switches and fabric rules ” on page 135
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
