|SI-13 (1) Transferring Component Responsibilities || |
The organization takes information system components out of service by transferring component responsibilities to substitute components no later than Assignment: organization-defined fraction or percentage of mean time to failure.
|SI-13 (2) Time Limit On Process Execution Without Supervision || |
Withdrawn: Incorporated into SI-7 (16).
|SI-13 (3) Manual Transfer Between Components || |
The organization manually initiates transfers between active and standby information system components Assignment: organization-defined frequency if the mean time to failure exceeds Assignment: organization-defined time period.
|SI-13 (4) Standby Component Installation / Notification || |
Automatic or manual transfer of components from standby to active mode can occur, for example, upon detection of component failures.
The organization, if information system component failures are detected: SI-13 (4)(a)
Ensures that the standby components are successfully and transparently installed within Assignment: organization-defined time period; and SI-13 (4)(b)
Selection (one or more): activates Assignment: organization-defined alarm; automatically shuts down the information system.
|SI-13 (5) Failover Capability || |
Failover refers to the automatic switchover to an alternate information system upon the failure of the primary information system. Failover capability includes, for example, incorporating mirrored information system operations at alternate processing sites or periodic data mirroring at regular intervals defined by recovery time periods of organizations.
The organization provides Selection: real-time; near real-time Assignment: organization-defined failover capability for the information system.
