Appl. No.:

10/693710

Inventors:

Viswanath Krishnamurthy - Sunnyvale CA, US
Daniel Delfatti - Belmont CA, US

Assignee:

Sun Microsystems, Inc. - Santa Clara CA

International Classification:

G06F 11/00

US Classification:

713320, 713321, 713322, 713323, 713324, 714 6, 714 11, 714 13

Abstract:

A system and method is provided to allow a computer network system to keep a device in a powered off state over a power cycle. A service processor stores the power state information or power mask corresponding to the field replaceable unit (FRU) slots in a non-volatile storage location. As a result, after the system has been powered off and on, the power mask information is retained. Accordingly, a hotswap controller may then retrieve the power mask from storage to determine whether a given FRU should be powered on or kept in a powered off state. Depending on the power mask, the service processor will not power on the FRU if the power mask indicates that the device should remain in a powered off state. A management entity may update the power mask information depending on predetermined parameters or the condition of the FRU. As a result, a power mask may be maintained for several power cycles to keep a device in a powered off state.

International Classification:

G06F 11/00

US Classification:

714 47, 714 7, 714 13

Abstract:

A method for operating a system comprising multiple resources. The method comprises identifying for each resource a set of one or more failure risks for that resource. For each identified failure risk, a likelihood of failure is combined with an expected resolution time to provide a risk weight for the identified failure risk. For each resource, the risk weights for each failure risk are accumulated to provide an accumulated risk weight for the resource. A resource manager provisions workload across the multiple resources based on the accumulated risk weights for each resource.

International Classification:

G06F 9/46

US Classification:

718100, 718102, 718104

Abstract:

One embodiment of the invention provides a method for performing a service operation on a computer system. The method includes submitting a request for performing a service operation on the computer system and providing an estimated duration of the service operation. The service operation is expected to render one or more resources of the computer system unavailable for the duration of the service operation. It is therefore determined whether or not to accept the requested service operation based on planned usage of the one or more resources for the duration of the service operation.

US Classification:

710300000

Abstract:

The present invention relates to a management agent that can be ran on any operating system. More specifically, the management agent of the present invention is implemented with a set of application program interfaces (APIs) that allows the management agent to be independent of operating systems. The APIs makes the management agent portable across multiple operating systems. In an embodiment of the present invention, a Compact Peripheral Component Interconnect (CPCI) computer system includes a CPCI chassis, a circuit board located within the CPCI chassis, a first central processing unit (CPU) card coupled with the circuit board. The CPCI computer system also includes a second CPU card coupled with the circuit board, a first management agent located within said first CPU card, and a second management agent located within said second CPU card. The first and second CPU cards each respectively has a first operating system and a second operating system. The first management agent provides a local management service for the first CPU card and a system-wide management service for the first and second CPU cards. The second management agent provides a local management service for the second CPU card. In addition, a management interface is coupled with the first and second CPU cards. A network interface is coupled with the management agent for allowing the first and second management agents to interface with the first and second operating systems via the management interface. The first management agent systemically provides the system-wide management service for the first and second CPU cards with the first and second operating systems via the management interface. The second management agent may also provides a management information about the second CPU card to the first management agent via the management interface and the first management agent uses this management information to provide the system-wide management service.
