This glossary defines terms, abbreviations, and acronyms that apply directly to Intel® Ethernet FCoE.
TERMS | DEFINITIONS |
---|---|
ARP | Address Resolution Protocol |
Boot Targets | The server-side system in an FCoE SAN configuration. The FCoE Boot Target system hosts the FCoE target drives which are accessed by an FCoE Boot initiator. |
CEE | Converged Enhanced Ethernet |
Data Link Interface | Interface to the chip at the MAC layer. |
DCB | Data Center Bridging |
DCBX | DCB Exchange Protocol |
DDP | Direct Data Placement |
Descriptor Queues | Descriptor queues are used by software to submit work requests like send and receive and get completion status. |
DLL | Dynamic Linked Libraries |
DPT | Diamond Peak Technology |
ETS | Enhanced Transmission Selection |
FC | Fibre Channel |
FCF | Fibre Channel Forwarder |
FCoE | Fibre Channel over Ethernet |
HBA | Host Bus Adapter |
IPC | Inter Process Communication |
IRP | IO Request Packet |
iSCSI | Internet SCSI |
LLDP | Link Layer Discovery Protocol, IEEE802.1AB |
LUN | Logical Unit Number (LUN) is the identifier of a device which is being addressed by protocols such as Fibre Channel and iSCSI |
MPA | Marker Based PDU Alignment. This protocol runs on top of TCP and provides framing and data integrity. |
Native OS Stack | OS stack that represents a particular function implemented purely in software (e.g., native OS TCP/IP stack, native OS iSCSI stack). |
Native TCP/IP Stack | TCP/IP stack implemented in software and provided as part of the operating system. |
NFS | Network File System |
NIC | Network Interface Controller |
ODM | Offload Device Manager |
Offload Stack | Components that make up the offload stack |
OPS | Offload Protocol Switch |
Packet Buffers | Packet buffers are hardware FIFOs that either receive or transmit packets. Each packet buffer can be associated with one or more traffic classes |
PCI | Peripheral Components Interface |
PDU | Protocol Data Unit |
PFC | Priority Flow Control |
Raw Packet Driver | Standard Ethernet MAC driver. |
RDMA | Remote Direct Memory Access |
RDMAC | RDMA Consortium |
RSS | Receive Side Scaling is a mechanism for hardware to distribute receive packets to queues that are associated with a specific processor core and thereby distributing the processing load. |
RX | Receive |
SAN | Storage Area Network |
SCSI | Small Computer System Interface |
SNMP | Simple Network Management Protocol |
TLV | Type Length Value |
Transport Interface | Interface to the chip at the transport layer. |
TX | Transmit |
ULP | Upper Layer Protocol |
VBD | Virtual Bus Driver. Driver that exposes two virtual physical Devices on a single physical device and enables sharing of LAN and SAN traffic on a common Ethernet port. |
VFT | Virtual Fabric Tagging is a Fibre Channel defined extended frame header. |
VMDq | Virtual Machine Device Queues |
VLAN | Virtual LAN (VLAN) is a group of hosts with a common set of requirements that communicate as if they were attached to the same broadcast domain, regardless of their physical location. |
VT | Vanderpool Technology, also known as Virtualization. VT is an Intel-wide effort to support multiple virtual platforms on a single physical platform. This requires both software and hardware support to implement efficiently. |
