Abstract: Provided are a computer program product, system and method for determining adjustments to the spare space in a storage device unavailable to a user based on a current consumption profile of a storage device. A current write amplification is based on storage writes to a media at a storage device and host writes from a host to the storage device. An adjustment to the current write amplification is determined to produce an adjusted write amplification based on an estimated lifespan of the storage device, a maximum storage writes for the storage device, and the storage writes at the storage device since the storage device was powered-on. A determination is made to an adjustment to spare space based on the adjusted write amplification. The spare space and the free space available to the user are reconfigured to adjust the spare space by the determined adjustment to the spare space.

Abstract: An apparatus is described. The apparatus includes peer-to-peer intelligence to be integrated into a mass storage system having a cache and a backing store. The peer-to-peer intelligence is to move data between the cache and backing store without the data passing through main memory.

Abstract: Provided are an apparatus and method for persisting blocks of data and metadata in a non-volatile memory (NVM) cache. A non-volatile memory (NVM) cache caches blocks of data from the storage of the first block size and metadata for each of the cached blocks of data indicating a status of the cached block of data, including whether the block of data is modified or unmodified, and a location in the storage where the block of data is stored. The non-volatile memory has blocks of a second block size greater than the first block size, wherein one of the blocks in the non-volatile memory stores the block of data from the storage and the metadata for the block of data. A cache manager writes the block of data and the metadata for the block of data to one of the blocks in the non-volatile memory cache and writes the block of data in one of the blocks in the non-volatile memory cache to the storage.
