Abstract: A distributed storage system node is disclosed. The distributed storage system node may include at least one storage device, which may act as the primary replica for data subject to an Input/Output (I/O) request. A cost analyzer may calculate a local estimated time required to complete the I/O request at the primary replica, and a remote estimated time required to complete the I/O request at a secondary replica of the data. An I/O redirector may direct the I/O request to either the primary replica or the secondary replica based on the local estimated time required and the one remote estimated time required.

Abstract: Example object storage systems, bookkeeping engines, and methods provide quota enforcement 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 associated with requesting control entities are determined. Object usage values corresponding to the quota thresholds are determined. Data object access requests are denied responsive to object usage values exceeding quota thresholds for the requesting control entities.

Abstract: Various embodiments for implementing a switched direct attached shared storage architecture as disclosed herein include: providing a plurality of compute nodes, each compute node having integrated compute capabilities, data storage, and a network interface controller (Host NIC), the plurality of compute nodes being in data communication with each other via a local area network, the plurality of compute nodes each including distributed storage processing software resident thereon; providing a plurality of physical data storage devices in data communication with a storage controller; and enabling data communications in a data store switch fabric between the plurality of compute nodes and the plurality of physical data storage devices via the Host NIC and the storage controller, the data store switch fabric encapsulating data requests from the plurality of compute nodes into data frames for transport to corresponding physical data storage devices.

Abstract: A distributed storage system can include a storage node (125, 130, 135). The storage node (125, 130, 135) can include a Solid State Drive (SSD) or other storage device that employs garbage collection (140, 145, 150, 155, 160, 165, 225, 230), a device garbage collection monitor (205), a garbage collection coordinator (210), an Input/Output (I/O) redirector (215), and an I/O resynchronizer (220). The device garbage collection monitor (205) can determine whether any storage devices (140, 145, 150, 155, 160, 165, 225, 230) need to perform garbage collection. The garbage collection coordinator (210) can schedule when the storage device (140, 145, 150, 155, 160, 165, 225, 230) can perform garbage collection. The I/O redirector (215) can redirect read requests (905) and write requests (1005) away from the storage device (140, 145, 150, 155, 160, 165, 225, 230) when it is performing garbage collection.
