Abstract: A method and system for retrieving large contiguous data files is provided. The method divides the data during the storage operation such that it spans two or more logical volumes. The data may be stored over the plurality of volumes in any convenient manner such as in the case of two logical volumes, storing the even address data on one device and the odd address data on the other device. During an access request (either a read or a write) a host controller receiving the access request will generate as many access requests as are associated with the storage of the data to associated storage controllers. The storage devices are coupled via separate busses to their respective storage controllers and thus several storage devices may communicate with their associated controllers simultaneously. The data may now be delivered to the host controller from the two or more storage devices simultaneously thus drastically improving data throughput.

Abstract: A method and apparatus are for maintaining a cyclic redundancy check (CRC) byte is described which eliminates additional input/output (I/O) transactions for the case when a write to a partial sector is required while the CRC byte is maintained for an entire sector. The method includes performing an XOR operation between the partial write data and the data it is to displace, and then performing an XOR operation between the old CRC byte associated with the sector and the result of the XOR operation between the partial write data and the data it is to displace.
