FCoE protocols supported

Ethernet jumbo frames
The basic assumption underlying FCoE is that TCP/IP is not required in a local data center network
and the necessary functions can be provided with Enhanced Ethernet. The purpose of an
“enhanced” Ethernet is to provide reliable, lossless transport for the encapsulated Fibre Channel
traffic. Enhanced Ethernet provides support for jumbo Ethernet frames and in-order frame delivery.
The Fabric OS FCoE 10 Gbps converged network adapter supports jumbo packets of up to 9 KB,
compared to the original 1,518-byte maximum transmission unit (MTU) for Ethernet. The frame size
increase allows the same amount of data to be transferred with less effort.
FCoE protocols supported
The Fabric OS FCoE converged network adapter supports two layers of protocols: Ethernet link layer
and FCoE layer.
Ethernet link layer protocols supported
The following protocols support the Ethernet link layer:
•
802.1q (VLAN)
•
802.1Qaz (Enhanced Transmission Selection)
•
802.1Qbb (priority-based flow control)
•
802.3ad (link aggregation)
•
802.3ae (10 Gb Ethernet)
•
802.1p (priority encoding)
•
IEEE 1149.1 (JTAG) for manufacturing debug and diagnostics
•
IPv4 specification (RFC 793/768)
•
IPv6 specification (RFC 2460)
•
TCP/UDP specification (RFC 793/768)
•
ARP specification (RFC 826)
•
RSS with support for IPV4TCP, IPV4, IPV6TCP, IPV6 hash types
•
HDS (Header-data split)
FCoE protocols
The following protocols support Fibre Channel over Ethernet:
•
FIP (FC-BB5 compliant):
-
Support for FIP Discovery protocol for dynamic FCF discovery and FCoE link management
-
Support for FPMA and SPMA type FIP fabric login
•
Support for Initiator mode only (FCP-3 compliant in Initiator mode)
•
SCSI protection information support
•
IP-over-FC
•
NPIV support
