Abstract

Disclosed is a new security mode for a dense server environment. An authorized person will place a server chassis which is populated with multiple server blades in a secure mode. Using the provided utility, the authorized person will define events and actions to take once an event is detected in the server blade chassis. The utility provides the authorized user with a very flexible tool to implement a security policy which can satisfy most if not all business security needs.

Blade Chassis with Tampering Protection

        A Blade Center Chassis can contain up to 14 individual blade processors. Depending on the software environment of the chassis the blades can be operating independently or as partitioned groups or clusters. When operating in groups, the operating environment typically will accommodate the failure of an individual blade and continue processing in a degraded fashion. The maintenance module (MM) will more than likely also detect the failed blade and send an alert to a predesignated destination so that appropriate actions can be taken. This type of error recovery is satisfactory in a typical business organization.

     However, if a server blade is removed from the chassis without permission, this type of recovery can mask or mislead the administrator into letting typical error recovery takeover until the blade can be physically removed and replaced which may be a long period of time as the chassis may be physically located at a remote site and the degraded performance may be satisfactory to allow work to continue. This may be unsatisfactory for certain applications such as in a secure facility. This invention adds a level protection until the administrator can get out to replace the missing blade(s) and recover from the unauthorized action.

     In order to help contain or limit damage when an unauthorized removal or insertion event occurs, a new security mode will be added to the Blade Center (TM) Chassis. The system owner or administrator will use a utility provided and executed on the maintenance module. When the utility is invoked, the administrator will place the chassis into a secure mode by installing a new passwor...
