FCoE
FCoE allows Fibre Channel protocol to be transferred over Ethernet. FCoE
preserves existing Fibre Channel infrastructure and capital investments. The
following FCoE features are supported:
 Full stateful hardware FCoE offload
 Receiver classification of FCoE and FCoE initialization protocol (FIP)
frames. FIP is used to establish and maintain connections.
 Receiver CRC offload
 Transmitter CRC offload
 Dedicated queue set for Fibre Channel traffic
 Data center bridging (DCB) provides lossless behavior with priority flow
control (PFC)
 DCB allocates a share of link bandwidth to FCoE traffic with enhanced
transmission selection (ETS)
 Supports Technical Committee T11 Fibre Channel - Link Services (FC-LS)
specification; N_Port ID virtualization (NPIV) on Linux and Windows
Power Management
The adapter speed setting will link at the configured speed for WoL when the
system is powered down.
Adaptive Interrupt Frequency
The adapter driver intelligently adjusts host interrupt frequency based on traffic
conditions to increase overall application throughput. When traffic is light, the
adapter driver interrupts the host for each received packet, minimizing latency.
When traffic is heavy, the adapter issues one host interrupt for multiple,
back-to-back incoming packets, preserving host CPU cycles.
NOTE
Dell
®
supports WoL on only one adapter in the system at a time.
For specific systems, see your system documentation for WoL support.
