[NFS-Ganesha-Devel] Ganesha with GPFS

If we use Ganesha will GPFS , user api will be NFS and we will lose most of GPFS functionalities, like writing into single file parallelly. Is my understanding correct? If so, how can we get parallel write performance on a file with NFS Ganesha? Is my better option is to give up on Ganesha and use Luster/Gluster directly? I need open source code. -alok
