    摘要: A method begins by a requesting entity issuing a rebuild request regarding an encoded data slice to at least some of a set of distributed storage (DS) units. In response to the rebuild request, the method continues with each of at least some of the DS units of the set of DS units generating a partial slice corresponding to the encoded data slice to be rebuilt based on one of a set of encoded data slices stored by the respective DS unit to produce an array of partial slices. The method continues with the at least some of the DS units encrypting the array of partial slices using a set of encryption keys to produce an array of encrypted partial slices. The method continues with the requesting entity rebuilding the encoded data slice from the array of encrypted partial slices.

    摘要: A distributed storage system comprising: an infrastructure layer including interconnected computer nodes, wherein: each one of the interconnected computer nodes comprising processing resources configured to execute a Unified Distributed Storage Platform (UDSP) agent configured to: receive a task having assignments, calculating grades for assignments such that each grade is indicative of a suitability to execute assignments while meeting at least one Service Level Specification (SLS) requirement. The grade is calculated based on storage related resources parameters data. The task is routed to a more suitable computer node based on the calculated grades. The updated infrastructure layer is created in response to adding interconnected computer nodes and executing assignments of following tasks or routing the following tasks to a more suitable computer node based on the calculated grades.

    摘要: A multi-cloud data replication method includes providing a data replication cluster comprising at least a first host node and at least a first online storage cloud. The first host node is connected to the first online storage cloud via a network and comprises a server, a cloud array application and a local cache. The local cache comprises a buffer and a first storage volume comprising data cached in one or more buffer blocks of the local cache's buffer. Next, requesting authorization to perform cache flush of the cached first storage volume data to the first online storage cloud. Upon receiving approval of the authorization, encrypting the cached first storage volume data in each of the one or more buffer blocks with a data private key. Next, assigning metadata comprising at lest a unique identifier to each of the one or more buffer blocks and then encrypting the metadata with a metadata private key. Next, transmitting the one or more buffer blocks with the encrypted first storage volume data to the first online cloud storage. Next, creating a sequence of updates of the metadata, encrypting the sequence with the metadata private key and then transmitting the sequence of metadata updates to the first online storage cloud.

    摘要: Disclosed are apparatus and methods for facilitating caching in a storage area network (SAN). In general, data transfer traffic between one or more hosts and one or more memory portions in one or more storage device(s) is redirected to one or more cache modules. One or more network devices (e.g., switches) of the SAN can be configured to redirect data transfer for a particular memory portion of one or more storage device(s) to a particular cache module. As needed, data transfer traffic for any number of memory portions and storage devices can be identified for or removed from being redirected to a particular cache module. Also, any number of cache modules can be utilized for receiving redirected traffic so that such redirected traffic is divided among such cache modules in any suitable proportion for enhanced flexibility.
