Input/output request shipping in a storage system with multiple storage controllers |
摘要 |
Systems and methods presented herein provide for input/output shipping between storage controllers in a storage system. One storage system comprises a plurality of logical volumes, a host driver operable to process input/output requests to the logical volumes, and a plurality of storage controllers coupled between the server and the logical volumes. A first of storage controllers is operable to receive an input/output request from the host driver for one of the logical volumes, and transfer a command to a second of the storage controllers to retrieve the data of the input/output request. The second storage controller processes the command from the first storage controller, and retrieves the data associated with the input/output request. |

1. A storage system, comprising:
a plurality of logical volumes; a host driver operable to process input/output requests to the logical volumes; and a plurality of Serial Attached Small Computer System Interface (SAS) storage controllers coupled between a server and the logical volumes and communicatively coupled to one another, wherein a first of the storage controllers is operable to receive a write input/output request from the host driver for one of the logical volumes via a Peripheral Component Interconnect Express (PCIE) bus, and transfer a command to a second of the storage controllers via the PCIE bus to retrieve data of the input/output request from the host driver; wherein the second storage controller processes the command from the first storage controller, retrieves the data of the input/output request from the host driver via the PCIE bus based on the command, and writes the retrieved data to a logical volume of the plurality of logical volumes. |
