Multi-port data storage device capabilities can be provided by a remote host connected to a diskgroup that has a first single port data storage device and a second single port data storage device. Initialization of a first logical volume and a second logical volume in each single port data storage device allows a data access request to be serviced from the remote host with the first logical volume of the first single port data storage device. Data virtualized from the first logical volume of the first single port data storage device to the second volume of the second single port data storage device allows accessing the second volume of the second single port data storage device in response to a request to a data request to the first volume of the first single port data storage device.
A method comprising:
A system comprising a remote host connected to a diskgroup comprising a first single port data storage device and a second single port data storage device, the diskgroup comprising a first controller connected to the first single port data storage device and a second controller connected to the second single port data storage device, each controller comprising a multipath I/O circuitry and a remote data memory access module, each single port data storage device initialized with a first logical volume and a second logical volume by the respective first controller and second controller, the first logical volume of each single port data storage device accessed by the remote data memory access module of a controller of a different single port data storage device to store data to service a data access request from the remote host, the second logical volume of each data storage device configured to accessed by the remote data memory access module of a controller of a different single port data storage device to store data emulated from a different single port data storage device of the diskgroup, the second volume of at least one single port data storage device of the diskgroup accessed by a remote data memory access module in response to data request to the first volume of the first single port data storage device.
