What will replace SharedDisk on Netbackup 7.0?

Looking for a solution to a SharedDisk problem I findout under the Netbackup 5.x Best Practices for Disk Layout with Flexible Disk Option on page 4, point 1.2 that SharedDisk will no longer be supported on Netbackup 7.0, what will replace this technology? PureDisk? or just gona get decom? I never liked the way it worked mounting and dismounting LUN's but is there and we need to know what is the next step for this solution.

If any one have any feedback or more recent news all are wellcome.
Regards.
