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. |
