Abstract:
A block of a storage device of a plurality of storage devices is allocated for storage of data, wherein the allocation comprises identifying a nonce associated with the block of the storage device. An erase command for the block is transmitted to the storage device, the erase command comprising the nonce, wherein the storage device is to erase the block upon determining that the nonce matches a corresponding nonce stored locally at the storage device.
