Abstract: A configuration manager federated bean is provided for each host computer in the three-tiered management system. The configuration manager federated bean for a host computer is contacted by federated beans that manage each of the data services when a data service starts and stops using a data storage volume associated with the host computer. The configuration manager bean maintains persistent configuration information for each data service. In one embodiment, configuration manager beans can operate in a clustered environment where several beans store configuration information in a single storage area. Each of the beans implements an arbitration protocol so that only one bean writes to the storage area at any given time.

Abstract: Provided is a method and an apparatus for allocating contiguous chunks of physical address space. Specifically, the contiguous chunks are homogenized by allocating kernel pages from kernel page free lists and user pages from a user page free list. The kernel page free lists are a nonrelocatable kernel page free list and relocatable kernel page free list. The user page free list has free pages that populate the relocatable kernel page free list. Each page that populates the relocatable kernel page free list includes an identifier such that the identifier permits the addition of the page to the relocatable kernel page free list. By providing three types of page free lists, satisfied requests for free pages from the page free lists create contiguous chunks of physical address space.

Abstract: One embodiment of the present invention provides a system that supports compatibility testing of functionality provided through an Application Programming Interface (API) on a computing device. During operation, the system loads a client testing module on the computing device. The system also loads a remote testing module on a server. Once the client testing module and the remote testing module have been loaded, the system identifies a communication protocol that is available between the computing device and the server, and configures a communication-protocol-specific portion of the client testing module to communicate with the remote testing module through the available communication protocol. The system then compatibility tests the functionality provided through the API on the computing device. During this compatibility testing, certain portions of the test execute within the client testing module while other portions of the test execute within the remote testing module.

Abstract: A method and mechanism for observation, testing, and diagnosis with scan chains. A device under test is configured to support scan chains. The device includes multiple blocks, each of which are configured to be individually tested with separate scan chains. Each block is configured to recirculate the scan output of its block back into its scan chain during the cycles in which it is not being directly scanned out of the chip. As the scan clock is pulsed N cycles and another block of the chip is scanned out, the recirculated state of the block will shift within the block N positions. By keeping track of the scan chain lengths of each of the blocks in the chip, and the order in which they are scanned, a determination may be made as to which element of the scan chain will be shifted out of the next block to be scanned.

Abstract: A technique for actively shielding a signal such that a signal driver of the signal only participates in discharge events is provided. Because the signal driver only participates in discharge events, the signal driver is non-interacting with respect to other driver devices. Shield wires are set such that an active transition on the signal causes a discharge of capacitance between the signal and the shield wires.
