Abstract
A storage system is protected from tampering of software executed by the storage system. The storage system includes a first storage controller and a second storage controller. The first storage controller includes a first input and output controller configured to input and output host data, and a first management controller. The second storage controller includes a second input and output controller configured to input and output host data, and a second management controller. The first management controller is configured to store a backup of software of at least one of the second storage controller or the first input and output controller. A copy of tampered software of the at least one is stored. The tampered software of the at least one is recovered by the backup.
Claims8
A storage system comprising:
- a first storage controller;
- and
- a second storage controller, wherein
- the first storage controller includes a first input and output controller configured to input and output host data, and a first management controller,
- the second storage controller includes a second input and output controller configured to input and output host data, and a second management controller,
- the first management controller is configured to store a backup of software of at least one of the second storage controller or the first input and output controller,
- a copy of tampered software of the at least one is stored, and
- the tampered software of the at least one is recovered by the backup.
A method for inspecting tampering of software in a storage system, wherein
- the storage system includes
- a first storage controller, and
- a second storage controller,
- the first storage controller includes a first input and output controller configured to input and output host data, and a first management controller,
- the second storage controller includes a second input and output controller configured to input and output host data, and a second management controller,
- the first management controller is configured to store a backup of software of at least one of the second storage controller or the first input and output controller, and
- the method comprises:
- by the storage system,
- inspecting the software of the at least one;
- storing a copy of the software of the at least one in which tampering is detected by the inspection;
- and
- recovering the tampered software of the at least one by the backup.
