Glossary

cloud computing

Cloud computing provides a user with a virtual machine which is based on shared resources and services.

ES2 ML2 Mechanism Driver

See Oracle Ethernet Switch ML2 Mechanism Driver.

ES2

ES2 refers to an Oracle Ethernet Switch, such as the Oracle Switch ES2-72 and Oracle Switch ES2-64.

interface

OpenStack supports these interfaces:

• OpenStack UI, also known as Horizon

• OpenStack CLI

• OpenStack Rest API

L2

L2 (Level 2) is one of seven levels in the OSI mode of the communications functions of a computing system. The model divides communication functions into seven abstract layers. Level 2 is the data link layer that links two directly connected nodes in a local area network (LAN).

mechanism driver

Each networking mechanism is managed by an ML2 MechanismDriver. The MechanismDriver is responsible for taking the information established by the TypeDriver and ensuring that it is properly applied given the specific networking mechanisms that have been enabled.

ML2

Modular layer 2. See OpenStack Neutron ML2 plugin.

OFM

Oracle Fabric Manager is a GUI that manages and provisions virtual I/O.

OpenStack

OpenStack is a free, open-source, cloud-computing software platform. The technology consists of a series of software modules that control pools of processing, storage, and networking resources.

OpenStack Neutron

OpenStack Neutron is the module for managing networks and IP addresses for OpenStack cloud-computing software.

OpenStack Neutron ML2 plugin

The OpenStack Neutron Modular Layer 2 (ML2) plugin is a framework allowing OpenStack Neutron to simultaneously use different industry-standard Layer-2 solutions, including OpenvSwitch, linuxbridge, and HyperV L2.

Oracle Ethernet Switch ML2 Mechanism Driver

The Oracle Ethernet Switch ML2 Mechanism Driver allows OpenStack installations to configure network connectivity for Oracle VMs on Oracle Ethernet Switches

Oracle Virtual Networking ML2 Mechanism Driver for OpenStack Neutron

This is an incompatible version of mechanism driver and is used only for installations of OpenStack on Oracle Virtual Networking (OVN) systems. This document deals with the Oracle Ethernet Switch ML2 Mechanism Driver for OpenStack Neutron instead of the OVN version.

To install OpenStack on OVM systems, refer to the Oracle Virtual Networking ML2 MechanismDriver for OpenStack Neutron Installation Guide.

OSI model

Open Systems Interconnection model.

OVM

OVM is Oracle Virtual Machine (VM)

OVS

OVS is OpenvSwitch agent, a part of the OpenStack software.

Plug-in

An OpenStack plugin is a module that is designed to be easily replaced by a module that you have customized to investigate and test new software concepts.

tenant network

A tenant network is a VLAN network for an Oracle VM that is connected to an Oracle Ethernet Switch.

type driver

Each available network type is managed by an ML2 TypeDriver. TypeDrivers maintain any needed type-specific network state, and perform provider network validation and tenant network allocation.

VLAN

Virtual local area network (LAN).

VM

VM is a virtual machine, a virtual computer composed of processing power and memory supplied by a physical server. A single server can provision a relatively large number of VMs with high-speed access to networks and VLANs, virtual storage, a shared printer, and other resources.
