摘要： The method of operating a storage system includes executing a storage service providing storage of a volume unit to at least one host device, in which the volume includes a first volume and a second volume. The method includes giving a first priority and a second priority lower than the first priority to the first volume and the second volume, respectively, and recovering meta-data for the first volume having the first priority when the storage service is stopped. The method includes starting the storage service using the recovered meta-data for the first volume, and recovering meta-data for the second volume having the second priority.

摘要： A computing system a storage device and a file system. The storage device includes a storage area having flash memory. The file system is configured to divide the storage area into multiple zones, multiple sections and multiple blocks, and to write a log in each block. The file system includes a block allocation module. The block allocation module is configured to allocate a target block, in which a log is to be written, by a continuous block allocation method according to which a block having a continuous address with a most recently selected block is set as the target block. The block allocation module is further configured to find a free section from the multiple sections when it is not possible to allocate the target block by the continuous block allocation method, and to set a block in the found free section as the target block.

摘要： A storage device, a directory entry lookup method for the storage device, and a host running the method can provide a quick directory entry lookup. The host includes an interface for exchanging data with the storage device which stores a multi-level hash table comprising directory entries of each directory, and a file system module receiving a file lookup command designating a target directory and a target filename, calculating a hash value which reflects the target filename and a lookup level, and searching for a directory entry which comprises the target filename in a bucket corresponding to the hash value from among buckets at the lookup level which are included in a multi-level hash table of the target directory. If the search for the directory entry fails, the file system module increases the lookup level and again calculates the hash value and searches for the directory entry for the target filename.

摘要： A host configured to interact with a storage device includes a write-back (WB) cache configured to write data to the storage device, a cache managing module configured to manage the WB cache, and a file system module configured to determine whether live blocks in victim segments among a plurality of segments stored in the storage device are stored in the WB cache, to read the live blocks from the storage device as a consequence of determining that the live blocks are not stored in the WB cache, to load the read live blocks to the WB cache, and to request the cache managing module to set dirty flags for the stored live blocks.
