Abstract
A storage system includes a storage controller and storage media for reading data from or writing data to the storage media in response to SCSI, NFS, CIFS, or HTTP type read/write requests. The storage controller includes SCSI, NFS, CIFS, and HTTP interface adapters for receiving the read/write requests and effecting the reading of data to or the writing of data to the storage media.
Claims12
A storage system for handling input/output (I/O) requests from a plurality of processors, comprising:
- a storage media including a plurality of disk units;
- a first interface adaptor to be coupled to a first processor of the processor;
- and
- a second interface adaptor to be coupled to a second processor of the processor,
- wherein the first interface adaptor is configured to receive a first block I/O request from the first processor, and
- determine a first logical volume to be accessed by the first processor based on the first block I/O request, the first logical volume being mapped to a first portion of the storage media,
- wherein the second interface adaptor is configured to receive a file I/O request from the second processor, and
- convert the file I/O request to a second block I/O request.
In a storage system with a storage media including a plurality of disk units, a method for handling input/output (I/O) requests from a plurality of processors, comprising:
- when receiving a block I/O request from a first processor of the processors;
- determining a first logical volume to be accessed by the first processor based on the first block I/O request, the first logical volume being mapped to a first portion of the storage media,
- when receiving a file I/O request from a second processor of the processors;
- converting the file I/O request to a second block I/O.
