Abstract: A file system layout apportions an underlying physical volume into one or more virtual volumes of a storage system. The virtual volumes having a file system and one or more files organized as buffer trees, the buffer trees utilizing indirect blocks to point to the data blocks. The indirect block at the level above the data blocks are grouped into compression groups that point to a set of physical volume block number (pvbn) block pointers.

Abstract: Presented herein are methods, non-transitory computer readable media, and devices for writing, allocating, and caching contents of a hard disk drive block on a solid state drive cache in a memory system, without requiring an inode context. The method includes: identifying one or more HDD blocks for caching by a storage server; assigning a physical block number to each identified HDD block; linking the identified HDD blocks to one another; allocating an SSD physical block number for each linked HDD block; and storing the physical block number for each identified HDD block and the physical block number for each corresponding SSD block within a cache map.
