TSM-VE: Enable the per VM multithread (process multiple vmdk from within a single backup job)

The idea is to be able to process more than one vmdk at a time, within a single VM backup job.
This would help a lot to handle huge virtual machine, by decreasing the overall backup elapsed time (as well as increasing the overall backup performance) when big virtual machine is/are part of a set of VM to be backed up by a datamover instance.
This would be done by adding an option to the datamover where we can specify the max number of vmdk to be processed in parallel, for each VM:
e.g: VMDKMAXPERVM=3
This parameter must be considered carrefuly, and linked to the existing parameter VMLIMITPERDATASTOR and VMLIMITPERHOST to avoid to much I/O against datastore ot ESXi hosts ...

    We understand this requirement and recognize the benefits this would offer. It is in alignment with our current strategy and is being considered for delivery in a future release. This should not be taken as a statement of commitment as plans and intent can change. We will provide an update when this is delivered or if there is a shift in plans.

    Hi,
    Let me update this RFE and specify that this feature would be greatly apprectied by those who are using ProtecTier. Indeed the single stream performance combined with this single thread per VM is big issue when you have to protect big virtual machine (let's say bigger than 300GB ) .
    The per VM multithread feature would allow user to leverage the PT performance when doing backups thourgh multi streams...
    Please carrefully considere this as an important pre requisite , since it is one of the biggest issue we are facing when deploying TSM-VE in VMware environment hosting bigger and bigger VM. LAstely, since the DP for VMware provide MS-SQL and Exchange selfcontains backups, it make even more sense to increase the possible backup speed , again, by backing up multiple VMDK of the same VM at the same time (thus multi thread VM backup )

Paraｌｌel backup in a VM using TSM for VE.

Need parallel backup in a VM to increase the backup performance (throughput). For example, each VMDK has the backup instances. In the current specification. of there is the VMFS snapshot, the input/output performance from the guest OS decreases.
