Abstract: One or more techniques and/or systems are provided for performing host side deduplication. Host side deduplication may be performed upon writeable data within a write request received at a host computing device configured to access data stored by a storage server. The host side deduplication may be performed at the host computing device to determine whether the writeable data is already stored by the storage server based upon querying a host side cache comprising data stored by a storage server and/or a data structure comprising unique signatures of data stored by the storage server. If the writeable data is stored by the storage server, then a deduplication notification excluding the writeable data may be sent to the storage server, otherwise a write command comprising the writeable data may be sent. Accordingly, unnecessary network traffic of redundant data already stored by the storage server may be reduced.

Abstract: Systems and methods herein obtain snapshots of one or more applications, while having minimal impact on performance of the applications. Embodiments may involve obtaining snapshots of modified application data within a node without disturbing the operations of the application. Systems may be configured to leverage the fast characteristics of local storage devices while utilizing the advantages provided by the remote storage of data. One or more applications may be preconfigured to record data modifications in one or more associated application state storages located on local memory. Further, one or more systems may operate in the background to identify modifications made to the associated application state storages and to determine an appropriate moment to take one or more snapshots of the stored data and transfer the one or more snapshots to one or more remote locations to be stored. Several factors may be used to determine when an appropriate moment has occurred.

Abstract: Systems and methods for efficiently using solid-state devices are provided. Some embodiments provide for a data processing system that uses a non-volatile solid state device as a circular log, with the goal of aligning data access patterns to the underlying, hidden device implementation, in order to maximize performance. In addition, metadata can be interspersed with data in order to align data access patterns to the underlying device implementation. Multiple input/output (I/O) buffers can also be used to pipeline insertions of metadata and data into a linear log. The observed queuing behavior of the multiple I/O buffers can be used to determine when the utilization of the storage device is approaching saturation (e.g., in order to predict excessively-long response times). Then, the I/O load on the storage device may be shed when utilization approaches saturation. As a result, the overall response time of the system is improved.
