Virtualized ocssds spanning physical ocssd channels

A system comprising:

• a first open-channel solid state drive comprising a first plurality of channels, each of the first plurality of channels comprising a respective plurality of blocks;
• and
• a data server comprising a processing unit to execute program code to cause the data server to:
• associate block addresses of a virtual address space of a first application with block addresses of one or more blocks of a first one of the first plurality of channels and with block addresses of one or more blocks of a second one of the first plurality of channels;
• receive, from the first application, a first I/O call associated with one or more block addresses of the virtual address space;
• determine block addresses of one or more blocks of the first one of the first plurality of channels which are associated with the one or more block addresses of the virtual address space;
• and
• execute the first I/O call on the determined block addresses of one or more blocks of the first one of the first plurality of channels.

A computer-implemented method comprising:

• receiving a request from a first application to create a virtual open-channel solid state drive associated with a first bandwidth and first capacity;
• in response to the request, associating block addresses of a virtual address space of the first application with block addresses of one or more blocks of a first one of a first plurality of channels of a first open-channel solid state drive and with block addresses of one or more blocks of a second one of a second plurality of channels of a second open-channel solid state drive;
• receiving, from the first application, a first I/O call associated with one or more block addresses of the virtual address space;
• determining block addresses of one or more blocks of the first one of the first plurality of channels which are associated with the one or more block addresses of the virtual address space;
• and
• executing the first I/O call on the determined block addresses of one or more blocks of the first one of the first plurality of channels.
