The arrow symbol ⇒ indicates a reference to another entry.
2 Terms
2.1 A-E
| Ansible playbook | Ansible playbooks are used to orchestrate the deployment of Ericsson components after the deployment of OpenStack core components. | |
| Atlas | Atlas is a set of management tools, that provides a web-based user interface to CEE services, and application life cycle management. Atlas is based on existing open source OpenStack components, Horizon and Heat. Atlas is connected to the CIC’s northbound interface and has no connectivity to the internal control networks. From CEE point of view, Atlas is a single VM, running in each region, without High Availability, and enables management of multiple CEE regions. Cloud Manager can centrally manage the infrastructure through the Atlas northbound interface and also directly the network infrastructure that is not managed by CEE, for example, DC-GW and DC-FW. | |
| CIC | Cloud Infrastructure Controller. The CIC domain. See vCIC. | |
| CLI | Command-Line Interface. A text-based user interface for management, as opposed to a GUI. Conveniences like command history, command completion, and context-sensitive help are provided. | |
| Cobbler | Fuel component, provisioning service. | |
| Compute | Compute provides compute capabilities to virtual applications. | |
| Compute host | A physical host dedicated to run compute nodes. | |
| Compute node | A node that runs the compute daemon, a VM instance that provides a wide range of services such as a web service and analytics. | |
| CSC | Cloud SDN Controller. The CSC provides an overlaid network connectivity for virtual or physical network functions within a data center. Service providers can use this product to set up logical overlay networks within the data center, automating network service provisioning and optimizing the use of their data center compute and networking investments. CSC is integrated with vCIC and consequently there are three instances of CSC in the CEE. CSC is based on ODL. | |
| CSS | Cloud SDN Switch. Cloud SDN Switch release 4. | |
| DC-GW | Data Center Gateway. Connectivity from the data center internal networks to data center external networks is realized through DC-GW. DC-GW acts as a gateway to the external networks. DC-GW in the datacenter resolves the local Ethernet connectivity to either an L2 or L3 VPN across the external networks, either through simple encapsulation, or interworking of encapsulations. DC-GW can provide both L2 and L3 connectivity to the enterprise VPN or private datacenter and L3 connectivity to the public internet, or virtualized L2 connectivity between cloud physical sites, that is, other data centers. Also, L3 VPN for data plane and control plane can be extended over DC-GW. | |
| DM-MPIO | Linux Device Mapper iSCSI multipath. | |
| enclosure | See shelf. | |
| ephemeral storage | Non-persistent block storage. | |
2.2 F-K
| Fuel | Fuel is an open source component for OpenStack software life cycle management, adding installation, update, and equipment management support for a CEE instance. | |
| HAProxy | Service used to provide a single north-bound IP address from the CIC cluster. | |
| host | A physical unit referring to the hardware, the operating system, or the hypervisor. | |
| host OS | An operating system running on a physical processor. | |
| hostname | A label assigned to a device on a computer network. | |
| Identity Service | Provide identity, token, catalog, and policy services. | |
| kickstart | Computer used to install CEE. | |
2.3 L-P
| LIA | Light Installation Agent. LIA is installed on each dedicated ScaleIO server and compute host with SDC. It enables the performance of various maintenance operations. | |
| ML2 | Modular Layer 2. The Modular Layer 2 plugin for Neutron in OpenStack. | |
| Nailgun | Python-based main Fuel component. Nailgun implements REST APIs and the deployment of data management, and manages the configuration data necessary for deployment. | |
| node | A logical device or operational unit in the network. | |
| object storage | Replicated storage of files. Only used internally, not exposed as a service to tenants. | |
| PCI |
Peripheral Component Interconnect. The format
is "DDDD:BB:SS.F" where:
| |
| playbook | See Ansible playbook. | |
| pod | A pre-integrated building block of HW and SW components. | |
| Puppet | The deployment service used to install OpenStack core components. | |
2.4 Q-T
| QSFP+ | Quad Small Form-factor Pluggable transceiver. QSPF+ supports data transfers up to 40Gb/s. | |
| region | A discrete OpenStack environment with dedicated API endpoints, that typically shares only the Identity Service with other regions. | |
| ScaleIO | Distributed storage solution from EMC2. | |
| SDC | ScaleIO Data Client. SDC is a lightweight device driver that exposes ScaleIO volumes as block devices to the application residing on the compute host. | |
| SDS | ScaleIO Data Server. SDS manages the capacity of a dedicated ScaleIO server. | |
| shelf | Describes placement in a cabinet. Also called subrack or enclosure. | |
| stratum | Level defining the distance from the network reference clock. A lower stratum value implies a more reliable time source. | |
| subrack | See shelf. | |
| Telemetry | Collect measurements about the use of the physical and virtual resources comprising deployed clouds. | |
| ToR | Top of Rack. Top of Rack switch (deprecated term, replaced by "traffic switch" or "physical switch"). | |
2.5 U-Z
| Units of measurement |
Due to conflicting standards
JESD100B.01 and ISO/IEC 80000:13 and colloquial use, OpenStack and
3PP documentation uses the K, M and G prefixes inconsistently. Also,
the host and guest OSs and individual OpenStack components use units
of measurement and prefixes inconsistently. To conform to relevant
3PP and OpenStack documentation, the units of measurement and prefixes
are used in the following manner in CEE documents:
Deviation from the definition described in this term is indicated in the affected document.
| |
| vCIC | Virtual Cloud Infrastructure Controller. The vCIC provides the infrastructure for running a cloud environment on supported hardware configurations. | |
| vCIC host | Physical host running a vCIC node. | |
| vFuel | vFuel is an Ericsson component based on Fuel, running as a VM, providing the runtime environment for Fuel services. | |
| VLAN | Virtual LAN. A logical LAN that is implemented on a physical LAN and carries a subset of the traffic, interconnecting a group of stations, so that they can communicate directly with each other, but not with stations on other VLANs. VLANs are used for traffic separation and efficient decoupling of broadcast domains. The separation of traffic in a VLAN is based on categorization of packets. In their headers, the packets on the LAN contain a VLAN identifier, which is unique to each VLAN. | |
| VNX | Family of central storage solutions from EMC2. | |
| VXLAN | Virtual eXtensible Local Area Network. VXLAN is a network virtualization technology that creates an overlay network by encapsulating the Ethernet packets of the customer into IP packets on the DC network infrastructure. VXLAN tunnels refer to VXLAN traffic between VTEPs, which are typically carried over an IPv4 network. VXLAN tunnels need to be created between the VTEPs. The VXLAN tunnels can be created through OVSDB, as typically used by CSC. | |
