Data storage apparatus providing host full duplex operations using half duplex storage devices

摘要

A data storage apparatus includes a command processor that receives write commands and data blocks from a host, the write commands comprising block ID's (BID) corresponding to data blocks; storage resources including semiconductor memory and mass storage; a data manager that selects storage resources and allocates selected resources to block ID's; a translation table to map a storage resource to the allocated block ID, and storage resources that are selected after receipt of the write command. A method is further provided for increasing performance in a storage device comprising a plurality of storage resources, transferring data to a storage resource that is available to transfer the data.

主权项

1. An apparatus configured to couple to a plurality of data storage resources, comprising:
a command processor configured to receive a write command and data blocks from a host computing device; a resource manager configured as a host to the plurality of data storage resources; a data manager coupled to the command processor and to the resource manager and configured to select, after receipt of the write command, one of the plurality of data storage resources according to an availability of the data storage resources to transfer data, the data manager being further configured to issue instructions to the resource manager to allocate the data blocks received from the host to the selected data storage resource; and a translation table configured to map the data blocks to the selected data storage resource.
