Abstract: A system that includes a plurality of nodes configured to execute storage transactions. The nodes include a first node and a plurality of other nodes. The storage transactions are grouped into transaction sets that are to be executed in a predetermined order that ensures that dependencies between the transactions are observed. A cluster sequencer that resides on the first node is configured to increment a sequence number that identifies an active transaction set of the transaction sets and send the sequence number from the first node to the plurality of other nodes. Upon receipt of the sequence number, each one of the plurality of other nodes begins executing the transactions of the active transaction set without waiting for confirmation that all of the plurality of other nodes have the same sequence number.

Abstract: A port processor to receive a read command in a target port. In response, use the target to process a data transfer that includes use of memory for the read transfer allocated by a storage array controller prior to receipt of the read command by the target port or while processing the data transfer and selectively mark such memory as repurposable. The port processor to receive a write command in the target port. In response to receipt of the write command, use the target to process a data transfer for the initiator associated with the write operation, wherein the process includes use of memory that the storage array controller pre-allocated or allocated based on receipt of the read command by the target port for the transfer to the storage array controller and marked as repurposable.

Abstract: Example implementations relate to determining lengths of acknowledgment delays for input/output (I/O) commands. In example implementations, a length of an acknowledgment delay for a respective I/O command may be based on cache availability, and activity level of a drive at which the respective I/O command is directed, after the respective I/O command has been executed. Acknowledgments for respective I/O commands may be transmitted after respective periods of time equal to respective lengths of acknowledgment delays have elapsed.

Abstract: A system that includes a storage drive and a controller communicatively coupled to the storage drive. The storage drive includes a first region of storage space that is mapped to a virtual volume and at least a second region of storage space reserved for over-provisioning operations. The controller is to unmap an operable portion of the first region of storage space in response to aging of the storage drive so that the unmapped portion can be used for over-provisioning operations.

Abstract: Example embodiments relate to a mesh topology storage cluster with art array based manager. The mesh topology storage may include a first pair of controller nodes to access a first storage volume, and a second pair of controller nodes to access a second storage volume. The mesh topology storage may include an array based manager (ABM) associated with the first pair of controller nodes to monitor paths to the first storage volume via the first pair of controller nodes and to monitor paths to the second storage volume via the second pair of controller nodes. The mesh topology storage may include a passive component associated with the second pair of controller nodes to route ABM-type communications of the second pair of controller nodes to the ABM.
