About Hitatchi Content Platform

A FileNet P8 fixed storage area can use Hitachi Content Platform 3.x as the fixed content device for storing content element files. The content elements can belong to documents from different object stores, and these objects stores can belong to different Filenet P8 domains. As with all other fixed storage areas, the content element files for a document are initially placed in an associated staging area. The files are later migrated to the Hitachi device when you check in the document.

The content element files on the Hitachi device are stored in a directory tree that has a structure like a file store directory tree. Using the Hitachi Namespace browser, you must manually create the base directory that contains the root directory for the directory tree. The directory tree is created automatically by the fixed content provider (FCP). The FCP is the Content Engine component that migrates the content element files to the Hitachi device. The FCP specifies the directory path and name for a file as part of an HTTP PUT operation when placing the file on the device. For information about FCP configuraiton parameters, see Vendor and configuration parameters (Hitachi Content Platform). The configuration parameters include a Directory Structure parameter that determines the depth and size of the content directory tree.

RESTRICTION The maximum size for a content element file that Content Engine can store on the Hitachi device is 2 GB. If the size of a content element file exceeds this maximum, the following error is generated when you attempt to check in the parent Document object: CONTENT_FXCA_CONTENT_EXCEEDS_MAX_SIZE.

A Hitachi device has a feature that allows separate versions of the same file to be created. Content Engine does not use this feature because content element files are treated as immutable.

Content element file names

The following name is an example of the way that Content identifies content element files on the Hitachi device:

FN{921D7DFF-1E2C-4096-9683-0BDCE9069CB3}{C165C546-B24B-4fd0-BE7D-84522319C80D}-0

The name consists of the following parts (with the part from the example shown in parentheses):

Retention periods

The content retention period is implemented as a date that the retention period expires such as 2036-10-19 12:56:01. A document and the content element files for the document can be deleted after the retention expiration date. The following objects and files have an associated content retention expiration date:

When a document is checked in, Content Engine sets the retention expiration date for the document and the content element files for the document. The date is based on the following storage area retention period settings:

Content element file data scrubbing

Data scrubbing is the activity of making the contents of a deleted file unreadable and unrecoverable by writing over the contents of the file. For staging area files, data scrubbing occurs in accordance with your selected delete method for the storage area. For Hitachi device files, when the storage area delete method is PURGE or DESTROY, Content Engine enables shredding for a file before deleting the file. File shredding is Hitachi terminology for data scrubbing. For information about file shredding, see the Hitachi documentation. For information about the storage area delete methods, see Storage area properties (Configuration tab).
