Abstract: A storage architecture of a storage system environment has a storage connector interface configured to exchange data directly between flash storage devices on a server and a storage array of the environment so as to bypass main memory and a system bus of the server. According to one or more embodiments, the storage connector interface includes control logic configured to implement the data exchange in accordance with one of a plurality of operational modes that deploy and synchronize the data on the flash storage devices and the storage array. Advantageously, the storage connector interface obviates latencies and bandwidth consumption associated with prior data exchanges over the main memory and bus, thereby enhancing storage architecture performance.

Abstract: In one embodiment, a flash-optimized, log-structured layer of a file system of a storage input/output (I/O) stack executes on one or more nodes of a cluster. The log-structured layer of the file system provides sequential storage of data and metadata on solid state drives (SSDs) to reduce write amplification, while leveraging variable compression and variable length data features of the storage I/O stack. The data may be organized as an arbitrary number of variable-length extents of one or more host-visible logical units (LUNs). The metadata may include mappings from host-visible logical block address ranges of a LUN to extent keys, as well as mappings of the extent keys to SSD storage locations of the extents. The storage location of an extent on SSD is effectively "virtualized" by its mapped extent key such that relocation of the extent on SSD does not require update to volume layer metadata.
