C

Capture

The process of scanning an image of a source server and saving the data into an archive format in the image depot.

Captured Image

An archived form of an image. A captured image is identified with a name assigned by DynaCenter.

Component

A reusable packaged collection of files that is distributed by DynaCenter to a target server during the deploy process.

Component Archive

A packaged collection of files that must be converted into a component before DynaCenter can distribute it to target servers as part of the image deploy process.

Content Files

Content files are supplemental files, scripts, patches, etc. that you deploy in a component to customize your deployed image.

Control Files

Control files store attributes and metadata for component content files. DynaCenter creates .filelist and .info.xml when it builds a component and places these control files in the directory above the root in the component directory.

Control Script

Script run by DynaCenter to allow for special processing during the deploy process.

D

Deploy

The process of moving a captured image from the image depot to a target server.

Deployed Image

An image that has been moved onto a target server.

Deployed Server

A server that has been provisioned with an image; a target server becomes a deployed server after the migration completes successfully.

Destination Subnet

The subnet where the source server is being migrated to (for example, your production subnet).

I

Image

A complete software image (OS, applications, data) that can be booted and run on a server.

Image Depot

Storage container for captured images. The depot must be routable to the MWS and to servers being managed by DynaCenter. There can be more than one depot.

M

Migrate

The process of capturing an image of a source server and deploying that image to a target server.

Note: The DynaCenter migration operation significantly reduces the time to migrate a server by combining the capture and deploy operations into a single operation.

MWS

The Management Workstation (MWS) runs DynaCenter and in some configurations serves as NAS for the image depot.

P

Profile

Settings that can be used to specify the storage to be captured for a server and that can replace the default configuration already in the image for deployment.

R

Repository

NAS-based storage location known to DynaCenter that holds metadata for images, files that are part of software components, and other data necessary for provisioning and manipulating images.

S

Server

A physical or virtual server capable of running software images.

Software Component

See Component.

Source Server

A server that is managed by DynaCenter for the purpose of migrating the server image.

Note: The terms source server and managed server are used interchangeably.

Storage Server

Any device that contains storage. Storage servers will typically be NAS or SAN devices that are large enough to store many captured images. The MWS functions as storage server that contains at least a repository of software components.

T

Target Server

A server that is managed by DynaCenter for the purpose of migrating a server image.
