A synchronous destage process is used to move data from shared global memory to back-end storage resources. The synchronous destage process is implemented using a client-server model between a data service layer (client) and back-end disk array of a storage system (server). The data service layer initiates a synchronous destage operation by requesting that the back-end disk array move data from one or more slots of global memory to back-end storage resources. The back-end disk array services the request and notifies the data service layer of the status of the destage operation, e.g. a destage success or destage failure. If the destage operation is a success, the data service layer updates metadata to identify the location of the data on back-end storage resources. If the destage operation is not successful, the data service layer re-initiates the destage process by issuing a subsequent destage request to the back-end disk array.

Aspects of the present disclosure relate to data cache management. In embodiments, a logical block address (LBA) bucket is established with at least one logical LBA group. Additionally, at least one LBA group is associated with two or more distinctly sized cache slots based on an input/output (IO) workload received by the storage array. Further, the association includes binding the two or more distinctly sized cache slots with at least one LBA group and mapping the bound distinctly sized cache slots in a searchable data structure. Furthermore, the searchable data structure identifies relationships between slot pointers and key metadata.

Aspects of the present disclosure relate to data cache management. In embodiments, a storage array's memory is provisioned with cache memory, wherein the cache memory includes one or more sets of distinctly sized cache slots. Additionally, a logical storage volume (LSV) is established with at least one logical block address (LBA) group. Further, at least one of the LSV's LBA groups is associated with two or more distinctly sized cache slots based on an input/output (IO) workload received by the storage array.

Embodiments of the present disclosure relate to managing communications between slices on a storage device engine. Shared slice memory of a storage device engine is provisioned for use by each slice of the storage device engine. The shared slice memory is a portion of total storage device engine memory. Each slice's access to the shared memory portion is controlled.

The embodiments disclosed herein utilize fluorescence polarization based preliminary screen to identify a putative set of Cas inhibitors from an initial set of candidate inhibitors. The primary screening assay is followed by secondary screening assay to validate the putative set of inhibitors selected by the preliminary screen. In some embodiments, the present disclosure includes compositions and methods are provided for the inhibition of the function of RNA guided endonucleases, including the identification and use of such inhibitors.

The system, devices, and methods disclosed herein relate to data ratio reduction technology adapted to reduce storage costs by weeding out duplicative data write operations. The techniques and systems disclosed achieve deduplication benefits by reducing the size of hash values stored hash tables used to compare unwritten data blocks to data that has already been written and stored somewhere in physical storage. The data deduplication systems, methods, and products facilitate deduplication at the block level as well as for misaligned data chunks within data blocks, that is an unwritten data block that has been stored sequentially in two different physical locations. The deduplication teachings herein are amenable to varying data block sizes as well as data chunk sizes within blocks. Our embodiments enhance computer performance by substantially reducing computational speeds and storage requirements attendant to deduplication systems using larger hash table data sizes.

A computer device may include logic configured to provide a centralized library for descriptive programming and other types of object descriptions to a testing script engine. The descriptive programming library may store test object descriptions for test objects associated with an application under testing. The logic may be further configured to provide a unification layer over all the object description types and to provide inheritance among the objects at the unification layer. The logic may be further configured to store a test object description, associated with a test object, in the descriptive programming library; identify a reference to the test object in a descriptive programming statement associated with the testing script engine; access the stored test object description in the descriptive programming library based on the identified reference to the test object; and identify an application object, associated with the application under testing, based on the stored test object description.
