摘要： Provided are a computer program product, system, and method for dynamically increasing capacity of a storage device. For address mappings, each addressing mapping indicates a storage device block address for a host block address and a compressed block size indicating a number of blocks storing compressed data for data written to the host block address starting at the storage device block address. Write data for a write request to a host block address is compressed to produce compressed data. A block size of the compressed data is less than request block size of the write data for the write request. Indication is made in the address mapping for the host block address of a storage device address at which to start storing the compressed data in the storage device and the compressed block size. The compressed data is sent to the storage device to write at the storage device block address.

摘要： Methods and apparatus related to efficient Solid State Drive (SSD) data compression scheme and layout are described. In one embodiment, logic, coupled to non-volatile memory, receives data (e.g., from a host) and compresses the data to generate compressed data prior to storage of the compressed data in the non-volatile memory. The compressed data includes a compressed version of the data, size of the compressed data, common meta information, and final meta information. Other embodiments are also disclosed and claimed.

摘要： Techniques and mechanisms to efficiently cache data based on compression of such data. The technologies of the present disclosure include cache systems, methods, and computer readable media to support operations performed with data that is compressed prior to being written as a cache line in a cache memory. In some embodiments, a cache controller determines the size of compressed data to be stored as a cache line. The cache controller identifies a logical block address (LBA) range to cache the compressed data, where such identifying is based on the size of the compressed data and on reference information describing multiple LBA ranges of the cache memory. One or more such LBA ranges are of different respective sizes. In other embodiments, LBA ranges of the cache memory concurrently store respective compressed cache lines, wherein the LBA ranges and are of different respective sizes.
