摘要： A field programmable gate array (FPGA), that includes a trusted FPGA logic, an untrusted FPGA logic and a monitor; wherein the monitor is configured to monitor the untrusted FPGA logic and prevent the untrusted FPGA logic from violating predefined constrains imposed on an operation of the untrusted FPGA logic; wherein the predefined constraints are stored in a memory region of the FPGA that is not accessible to the untrusted FPGA logic.

摘要： A system and a method of managing storage of cached data objects on a non-volatile memory (NVM) computer storage media including at least one NVM storage device, by at least one processor, may include: receiving one or more data objects having respective Time to Live (TTL) values; storing the one or more data objects and respective TTL values at one or more physical block addresses (PBAs) of the storage media; and performing a garbage collection (GC) process on one or more PBAs of the storage media based on at least one TTL value stored at a PBA of the storage media.

摘要： A computer-based system and method for providing a distributed write buffer in a storage system, including: obtaining a write request at a primary storage server to store data associated with the write request in a non-volatile storage of the primary storage server; and storing the data associated with the write request in a persistent memory of the primary storage server or in a persistent memory of an auxiliary storage server based on presence of persistent memory space in the primary storage server. The write request may be acknowledged by the primary storage server after storing the data associated with the write request in the persistent memory of the primary storage server or in the persistent memory of the auxiliary storage server.

摘要： A method and a system for accelerating computer data garbage collection (GC) on a non-volatile memory (NVM) computer storage device may include: monitoring, by a processor, a data validity parameter of at least one physical write unit (PWU), where the PWU may include a plurality of physical data pages of the NVM device; sending at least one GC command from the processor to an accelerator associated with the NVM device, based on the monitored data validity parameter; copying, by the accelerator, a plurality of data-objects stored on at least one first PWU, to a read address space comprised within the accelerator; copying valid data-objects from the read address space to a write address space comprised within the accelerator until the amount of data in the write address space exceeds a predefined threshold; and storing, by the accelerator, the data content in at least one second PWU in the NVM media.

摘要： In a storage system including a first tier and a second tier a method includes: storing access statistics per object; obtaining a request to perform a write operation; calculating a recency factor to the first object based on the access statistics; and writing the first object to one of the first tier and the second tier, depending on the recency factor. Performing garbage collection process on the second tier may include: reading metadata of an object stored in the second tier; determining whether the object is valid based on the metadata; if the object is invalid, discarding the object; and if the second object is valid: calculating a recency factor for the object based on the access statistics of the object; and moving the object to the first tier or leaving the object in the second tier, depending on the recency factor of the second object.

摘要： computer-based system and method for selecting a write unit size for a block storage device, includes performing a plurality of sequences of I/O operations to the block storage device, each sequence having a write unit size from a plurality of write unit sizes; collecting performance metrics of the sequences of I/O operations; and selecting the write unit size for the block storage device from the plurality of write unit sizes based on the performance metrics. In some cases, preconditioning is performed prior to performing the plurality of sequences of I/O operations by emptying the block storage device; and writing data to the block storage device to fill the block storage device above a predetermined level.
