I've only set this up on a Windows Server 2012 configuration therefore I cannot provide the exact steps on how to set one up in a client environment. That being said, a storage space/pool is essentially a virtual disk that resides on one or multiple physical disks allowing you to accumulate free space. For example if I have multiple servers with free space on their data drives I can then create a storage pool to accumulate this. To allocate this storage pool/space to a user or machine you will need to decide what you wish to do with it. Below are a couple of examples of how:
- Share via Windows Folder Sharing (UNC Path)
- Use iSCSI to use the current ethernet infastructure allowing you to assign the storage pool/space a drive letter to the client machine
- In a server environment you may wish to use it for DFS (Distributed File System) to maintain redundancy
Personally I use my storage pool as an iSCSI drive for which i have partitioned.
You can only use the free space of a non Windows install drive. To my knowledge you cannot overcome this with partitioning.
In relation to your second question, you will only able to use the share as a safepoint backup if it is shared via Windows Folder Sharing. For example: \\computername\share
Also you will need to make sure that the NAS is on the same workgroup as the Windows 8 machine hosting the storage pool otherwise it will not be able to find the share. Hopefully this is what you asking however please correct me if it isn't.
Hope This Helps,
