Retention for the Hitachi fixed content device

The fixed storage areas that are associated with a Hitachi fixed content device can operate in aligned or non-aligned retention mode. In both retention modes, Content Platform Engine manages retention. In the aligned retention mode, the fixed content device can provide an extra layer of retention protection.

Retention in aligned mode

In the aligned retention mode, the fixed content device applies the retention settings that you set by using Content Platform Engine. The fixed content device prevents other applications from deleting content that you set for retention.

The following table maps Content Platform Engine content-retention settings to the corresponding Hitachi device content-retention settings.

Content Platform Engine object retention setting	Hitachi object content retention setting
Not set	Deletion allowed (0)
Permanent	Deletion prohibited (-1)
Indefinite	Initial unspecified (-2)
Date value	Specific date value

Retention in unaligned mode

In the non-aligned retention mode, Content Platform Engine applies retention, but the fixed content device does not provide extra, device-level protection of the content. It is possible that another application that uses the fixed content device might delete content that you set for retention.
