Abstract: An example system includes an enclosure having a plurality of small computer system interface (SCSI) drives partitioned into a first zone including a first SCSI drive of the plurality of SCSI drives and a second zone including a second SCSI drive of the plurality of SCSI drives. The system includes a plurality of communication ports having a first port through which the first zone communicates; and a second port through which the second zone communicates. The system includes a management node configured to interact with the first SCSI drive in a first server as a first Internet SCSI (iSCSI) drive, and with the second SCSI drive in a second server as a second iSCSI drive.

Abstract: Example object storage systems, bookkeeping engines, and methods provide quota-based access control for control entities, such as accounts, users, and buckets. An object data store is configured to enable control entities to access data objects associated with each control entity. Quota thresholds and usage values are determined for control entities and used to determine a quota status. Quota status is used to determine data object access response based on the requesting control entities.

Abstract: These methods, systems, and other aspects can provide for adaptive distribution/re-distribution of data processing tasks. An example method may create, by a processor in a first node, a status object for a data processing task and assign, by the processor in the first node, the data processing task to a worker of a second node. Further, after a first period of time, the method may query, by the processor in the first node, the status object for a task status of the assigned data processing task reported by the second node. The task status reflects a status of execution of the assigned data processing task by the second node. The method determines, by the processor in the first node, to reassign the assigned data processing task based on a received task status reported by the second node, and reassign, by the processor in the first node, the assigned task.
