NFSD's pNFS block layout implementation supports the simple block volume type and the base SCSI volume type. These are single-device volumes. The pNFS block layout standard allows other configurations, such as striped blocks. We believe that these other configurations might enable better performance by increasing the number of concurrent I/O operations the client can have in flight per layout.
