Abstract: A server that monitors errors experienced by disk drives is disclosed. The server comprises an application stored in a memory; when executed by a processor sends a request to disk drives for a count of errors experienced by the disk drives. The application sends the request at a pre-defined time period. The application sends requests at multiple time periods. The application records the count of errors experienced by the disk drives, wherein the application records previous errors that have occurred on the disk drives over multiple time periods. The application determines an acceleration of errors experienced by the disk drives, wherein an acceleration of errors is a rate of change of the count of errors per the pre-defined time period. The application determines the acceleration of errors experienced by the disk drives. The application initiates corrective actions for at least one of the disk drives.

Abstract: A system for controlling access to a server computer comprising a server computer with a memory; an application residing in the memory of the server computer that, when executed by the computer, provides a first user with access to a primary-level session of the server computer, based on a first access key; provides the first user with a root-level session of the server computer, based on a second access key; prevents a second user from accessing the root from the primary level, while the root-level session of the first user is active; provides the second user with real-time observation of the actions taking place in the session of the first user; permits the first user and the second user to communicate with one another in real-time, during the root-level session; and logs the activity of root-level session.
