5 The SPDK "reduce" block compression scheme is based on using SSDs for storing compressed blocks of
6 storage and persistent memory for metadata. This metadata includes mappings of logical blocks
7 requested by a user to the compressed blocks on SSD. The scheme described in this document
14 This scheme only describes how compressed blocks are stored on an SSD and the metadata for tracking
15 those compressed blocks. It relies on the higher-software module to perform the compression

21 disk. The phrase "compressed blocks of storage" includes these uncompressed blocks.)
27 lowest-numbered blocks available on the backing storage device. This will ensure that when this
28 algorithm is used on a thin-provisioned backing storage device, blocks will not be allocated until
47 much the chunk was able to be compressed. The blocks on disk associated with a chunk are stored in…
117 * Allocate 2 blocks (0 and 1) from the free backing IO unit list. Always use the lowest numbered
198 * Allocate blocks 3 and 4 from the free backing IO unit list.
199 * Write the 5KB of data to blocks 3 and 4.
