摘要： A data storage system having protocol controller for converting packets between PCIE format used by a storage processor and Rapid IO format used by a packet switching network. The controller includes a PCIE end point for transferring atomic operation (DSA) requests, a data pipe section having a plurality of data pipes for passing user data; and a message engine section for passing messages among the plurality of storage processors. An acceleration path controller bypasses a DSA buffer in the absence of congestion on the network. Packets fed to the PCIE end point include an address portion having code indicating an atomic operation. An encoder converts the code from a PCIE format into the same atomic operation in SRIO format. Each one of a plurality of CPUs is adapted to perform a second DSA request during execution of a first DSA request.

摘要： A storage system and method is provided including physical storage devices controlled by storage control devices constituting a storage control layer operatively coupled to the physical storage devices and hosts. The storage control layer includes a first virtual layer interfacing with the hosts, operable to represent a logical address space available to said hosts and characterized by an Internal Virtual Address Space (IVAS); a second virtual layer characterized by a Physical Virtual Address Space (PVAS), interfacing with the physical storage devices, and operable to represent an available storage space; and an allocation module operatively coupled to the first and second virtual layers and providing mapping between IVAP and PVAS. Each address in PVAS is configured to have a corresponding address in IVAS. The allocation module facilitates management of IVAS and PVAS, enabling separation of a process of deleting certain logical object into processes performing changes in IVAS and PVAS, respectively.

摘要： A method of migrating data from a source storage resource to a destination storage resource involves selecting a source volume in the source storage resource; configuring in the destination storage resource a destination volume corresponding to the source volume and having the same properties; and redirecting I/O requests from an application running on a host to the destination volume instead of the source volume, whilst migrating data stored in the source volume to the destination volume. A storage system is operable as a destination storage system for migrating data from a source storage system, including means for configuring a destination volume corresponding to a source volume in the source storage system and a migration module having a non-transitory computer useable medium and operable to initiate read requests addressed to the source volume thereby enabling a background process of migrating data stored in the source volume to the destination volume.

摘要： A mass storage system and method incorporates a cache memory or a cache management module which handles dirty data using an access-based promotion replacement process through consistency checkpoints. The consistency checkpoints are associated with a global number of snapshots generated in the storage system. The consistency checkpoints are organized within the sequence of dirty data in an invariable order corresponding to storage volumes with the generated snapshots, such that, responsive to destaging a consistency checkpoint the global number of generated snapshots are recorded and then read during recovery of the failed storage system.

摘要： In a data storage system having a drive I/O command queue associated with a data storage device, contiguous I/O requests of at least a predetermined size may be processed in a pipeline mode of operation by issuing to the command queue a plurality of contiguous I/O request portions, each comprising a portion of the I/O request, so that a next one of the I/O request portions is in the command queue before the data storage system completes a current I/O request portion. The data storage device may implement I/O reordering based on data location and contain at least two device I/O command queues or, alternatively, may not implement such reordering and contain a single command queue. In one embodiment, a performance parameter of the data storage system, such as the bandwidth requirement for the contiguous I/O request, is monitored and the size of subsequent I/O request portions and/or the state of the pipeline mode of operation are adjusted accordingly. With this arrangement, large contiguous I/O requests can be executed at a higher bandwidth, without adversely impacting other I/O requests for the same device.
