All these third party clusterware vendors sell clusterware along with cluster file systems. If you wanna use their cluster file systems, yes, you need their cluster manager/clusterware to manage the cluster file system. The argument boils down to this: Do you have money to afford their cluster systems? Or do you go with raw/nfs/asm, as oracle recommends?
