Network File System | The |
(NFS) | for accessing files on an HSM file system from a remote machine, particularly a Linux client. |
offline file | A file whose contents were migrated to one or more FSE media (according to the number of |
| copies defined), and then removed from the HSM file system. The header and extended |
| attributes of an offline file are left intact and remain on the HSM file system. An offline file |
| becomes online at an FSE user's request, when its contents are recalled from the FSE media. |
offline medium | An FSE medium which is temporarily put out of operation and physically removed from the FSE |
| library. |
online file | A file on an HSM file system that is ready to be used by an application. A file is online |
| immediately after it is stored on the HSM file system, regardless of whether it was newly created |
| or recalled from FSE media. An online file becomes offline when it is released. |
online medium | An FSE medium that is physically present in the FSE library and which does not have its status |
| set to unusable. |
ordinary LAN | A network, usually a company LAN, to which systems are attached using their primary network |
| adapters. |
ordinary LAN | A connection between parts of the FSE implementation which uses ordinary LAN for |
connection | communication purposes. |
package | A package with FSE software that will be installed to an FSE implementation. |
(FSE package) |
|
partition | A configurable entity used by the FSE implementation to split the storage and configure it |
(FSE partition) | according to user requirements. Each FSE partition is related to a single HSM file system and |
| one or more FSE media pools. It has its own policies, File System Catalog, and Hierarchical |
| Storage Management Database. |
Partition Manager | An FSE daemon (service) that executes and controls the migration, release, and recall processes |
(PM) | for a single FSE partition, according to the policies defined in the FSE partition configuration |
| file. The Partition Manager process name is |
performance disk | A disk with a high throughput which stores HSM file systems. Depending on the location of a |
| particular HSM file system, it needs to be locally mounted either on the consolidated FSE system |
| or on an external FSE client. |
primary storage | A logical volume (disk partition) used to store the HSM file system. |

|
private network | A dedicated network to which systems are attached using their secondary network adapters. |
private network | A connection between parts of the FSE implementation which uses private network for |
connection | communication purposes. |
process | A process running on an FSE implementation that performs |
(FSE process) |
|
recall policy | A rule by which recall jobs for files on an HSM file system are conducted. Since recall is started |
| either implicitly or explicitly on an FSE user's request, the only configurable parameter specifies |
| the maximum time the user should wait for the file to become online. This parameter is defined |
| in the FSE partition configuration file. Each FSE partition has its own recall policy. |
recall retention time | A period of time during which a recalled file is kept online before it is released again. See also |
