    Abstract: Writing to storage disks using a differently sized sector format than that of the storage disk require sector edges to be read from sectors of the disks before awrite operation can occur. Write operations consequently incur a penalty by having to pre-read sector edges. A sector-edge cache avoids the performance penalty by storing sector edges obtained from the sectors during previously executed read and write operations. Rather than pre-reading a sector edge from disk during a write operation, an input/output controller can examine the sector-edge cache to determine if each appropriate sector edge is already present and then combine new data with that cached sector edge. RAID-5 implementations, which use a read-modify-write process to perform write operations, benefit from sector caches by reading and caching sector edges during the read phase so that no additional pre-reads are needed during the write phase.

    Abstract: Techniques are presented for sending an application instruction from a hosting digital appliance to a portable medium, where the instruction is structured as one or more units whose size is a first size, or number of bytes. After flushing the contents of a cache, the instruction is written to the cache, where the cache is structured as logical blocks having a size that is a second size that is larger (in terms of number of bytes) than the first size. In writing the instruction (having a command part and, possibly, a data part), the start of the instruction is aligned with one of the logical block boundaries in the cache and the instruction is padded out with dummy data so that it fills an integral number of the cache blocks. When a response from a portable device to an instruction is received at a hosting digital appliance, the cache is similarly flushed prior to receiving the response. The response is then stored to align with a logical block boundary of the cache.

    Abstract: A cache memory is utilized effectively because data redundancy elimination is executed. A controller manages the cache memory by dividing it into a first area and a second area. When receiving a write access request from an access requestor, the controller divides a data block, which is an access target, into a plurality of chunks and searches the first area first and then the storage apparatus based on each chunk. If chunk storage information, indicating that each chunk is stored in the storage apparatus, does not exist in the first area or the storage apparatus, the controller executes chunk storage processing and creates and stores the chunk storage information. If the chunk storage information exists, the controller eliminates the chunk storage processing for storing the chunks. If the chunk storage information does not exist in the first area, the controller stages the chunk storage information from the storage apparatus to the first area on condition that the first area has an unused area.

    Abstract translation: 由于执行了数据冗余消除，因此有效地利用了高速缓冲存储器。 控制器通过将高速缓冲存储器分成第一区域和第二区域来管理高速缓冲存储器。 当从访问请求者接收到写访问请求时，控制器将作为访问目标的数据块划分成多个块，并且首先基于每个块搜索第一区域，然后搜索存储装置。 如果指示每个块存储在存储装置中的块存储信息不存在于第一区域或存储装置中，则控制器执行块存储处理，并创建并存储块存储信息。 如果块存储信息存在，则控制器消除用于存储块的块存储处理。 如果第一区域中不存在块存储信息，则在第一区域具有未使用区域的条件下，控制器将块存储信息从存储装置分级到第一区域。

    Abstract: Provided are a cache management method and a cache device using a sector set. The cache management method includes receiving a write request of predetermined data to be written to a predetermined sector of a storage device, from a host device; determining whether a cache memory is allocated to a sector set including the predetermined sector; selectively allocating the cache memory to the sector set based on the result of determination; and storing the data requested to be written into the cache memory allocated to the sector set. According to the present invention, access speed of a flash memory may be increased by writing data of a whole sector set at a time.
