Methods, systems, and computer program products for identifying and enforcing software feature limits across different hardware platforms, software releases, and tiers are disclosed. According to one method, a feature limit data structure is stored on the hardware platform. Each entry in the feature limit data structure is indexed by at least a software program identifier, a software release level identifier, and a feature name. When software is initialized, its release level is determined. A feature limit manager separate from the software being initialized is invoked. At least the software program identifier, the release level, and the feature identifier are provided as input to the feature limit manager. The feature limit manager provides a feature limit value. The feature limit value is stored and the software uses the feature limit value to enforce the feature limit during execution.

A method, system, or computer program product for controlling access to software component features is disclosed. There are three available states for selectable component features. The three available states, of which one is selected, are: (i) enabled access to the selected software component features for users and other software component features on a data storage system, (ii) enabled access to the selected software component features by other software component features on a data storage system, or (iii) disabled access to the software component features.

A method allows point-in-time viewing of session data for multiple sessions being stored on a disk. Session bits are set for the session data in memory which points to the data at any particular point in time, and this can be done for multiple sessions. In order to make the session data persistent, separate session bits are stored in a portion of a disk reserved for such session bits. Thus, in the event of failure where session bits which are stored in volatile memory such as RAM, are lost, the duplicate copy set in the non-volatile memory can be used to recreate the session once the failure is corrected.
