  • Patent number: 9779027
    Abstract: Aspects of the present disclosure disclose systems and methods for managing a level-two persistent cache. In various aspects, a solid-state drive is employed as a level-two cache to expand the capacity of existing caches. In particular, any data that is scheduled to be evicted or otherwise removed from a level-one cache is stored in the level-two cache with corresponding metadata in a manner that is quickly retrievable. The data contained within the level-two cache is managing using a cache list that manages and/or maintains data chunk entries added to the level-two cache based on a temporal access of the data chunk.

  • Patent number: 9424314
    Abstract: Implementations of the present disclosure involve a system and/or method for joining read requests for the same data block sent to a storage appliance. The system and method is configured to receive the first read request for the data block at an I/O layer of the storage appliance. The I/O layer is configured to manage obtaining data blocks from one or more storage devices on the storage appliance. The system and method may then receive a second read request for the data block at the I/O layer of the storage appliance. The first and second read request may then be joined at I/O layer and only a single copy of the data block is returned to a cache in response to the first and second read requests.

  • Patent number: 8935481
    Abstract: Aspects of the present disclosure disclose systems and methods for managing a level-two persistent cache. In various aspects, a solid-state drive is employed as a level-two cache to expand the capacity of existing caches. Any data stored in the level-two cache may be stored in a particular version or format of data known as “raw” data, in contrast to storing the data in a “cooked” version, as is typically stored in a level-one cache.

  • Patent number: 7555541
    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.

  • Patent number: 7152104
    Abstract: Dedicated federated beans monitor an event service in a data services management system and sends human-readable messages to people involved in the administration of management services in order to inform the administrators that an event they are interested in has occurred. In one embodiment, the beans each contain a category list indicating which events are of interest to the administrators and the beans cooperate with each other to insure that the category lists in the beans are synchronized. In another embodiment, the federated bean composes and forwards e-mail messages to administrators. In still another embodiment, the federated bean also monitors and reports messages posted to a logging service.

  • Patent number: 7054890
    Abstract: A three-tiered data imaging system is used on a distributed computer system comprising hosts connected by a network. The lowest tier comprises management facade software running on each machine that converts a platform-dependent interface written with low-level kernel routines that actually implement the data imaging system to platform-independent method calls. The middle tier is a set of federated Java beans that communicate with each other, with the management facades and with the upper tier of the system. The upper tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. In one embodiment, the federated Java beans can run on any machine in the system and communicate, via the network. A data imaging management facade runs on selected hosts and at least one data imaging bean also runs on those hosts.

  • Patent number: 6996587
    Abstract: Data volumes on local hosts are discovered and managed by federated Java beans that run on each host. The Java beans form part of a three-tiered data services management. The lowest tier comprises management facade software running on each machine that converts platform-dependent interface written with the low-level kernel routines to platform-independent method calls. The middle tier is a set of federated Java beans that communicate with the management facades and with the upper tier of the system. The upper tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. The federated beans can configure and control data volumes with either a SCSI terminal emulation interface or a storage volume interface and use a logical disk aggregator to present all volumes available on a local host as a single “logical volume” in which all information regarding the various volumes is presented in a uniform manner.

  • Patent number: 6931427
    Abstract: A dedicated service finder runs on each host on which data management services run. This service finder caches handles that allow clients to manage the corresponding service and keeps track of other hosts that are also running the service finder. In one embodiment, the service finder registers itself with an existing lookup service so that a client can perform a single lookup for the service finder and then obtain other services from it. Accordingly, only a single lookup is required to obtain all the services running on a specific host. In accordance with another embodiment, the service finder monitors events generated by existing lookup services that occur when other service finders register with the lookup services. In this manner, the service finder can maintain a list of other hosts that have service finders running on them. This arrangement allows a client that has located one service finder to retrieve from that service finder information concerning other hosts and data services running on those hosts.

  • Patent number: 6772178
    Abstract: A three-tiered data replication management system is used on a distributed computer system connected by a network. The lowest tier comprises management facade software running on each machine that converts a platform-dependent interface written in low-level kernel routines that actually perform the data replication to platform-independent method calls. The middle tier is a set of federated Java beans, which communicate with each other, with the management facades, and with the upper tier of the system. The upper tier of the inventive system comprises presentation programs that can be directly manipulated by management personnel to view and control the system. The federated Java beans can run on any machine in the system and communicate via the network. A data replication bean runs on each host and at least one such bean communicates directly with a management interface that is controlled by a user.
