Device A device refers to a device managed by HPDM, such as a thin client.
Package A package is comprised of a description file and a folder that contains payload files. The
package name is identical to the folder name, which can be any legal string.
The name of the description file follows the convention PackageName-
ChecksumString.desc. The checksum is computed from all payload files in alphabetical
sequence of filename or folder name with depth-first traversal.
PXE PXE (Preboot eXecution Environment) is a network protocol used to start up computers using a
network interface that is independent of data storage devices or installed operating systems.
HPDM utilizes PXE to execute device image extraction and distribution. PXE is an optional
imaging mechanism best used for remote system recovery.
Rule A rule enables you to automate the execution of tasks. Each rule has three parts:
Filter—Defines which devices the rule applies to
Trigger—Defines when the rule is executed
Template—Defines what operation should be performed on the devices
Task A task is the scheduled action that execute task templates to a device or group of devices. A
task is comprised of a template, an execution schedule, and a list of target devices.
Task template A task template (or template) is an XML files that define the configuration changes or software
updates that administrators want the devices to perform. HPDM provides a variety of built-in
task templates for managing devices.
Task templates can be imported or exported by using tools in the HPDM Console. New task
templates can be downloaded from the HP FTP site and then imported into your HPDM Server.
Template sequence A template sequence (or sequence) is a special kind of task template that enables you to
connect several templates together and send them out for execution in one task.
Write filter A write filter provides the ability to write-protect a run-time image. By redirecting all write
requests to either a separate disk partition or RAM, a write filter allows the run-time image to
maintain the appearance of a writable run-time image. Additionally, a write filter provides the
ability to deploy a run-time image onto read-only media, such as a CD-ROM.
