My 1st Storage Device, SCv2020.

I've been given the go ahead to replace two aging HP servers with 2x Dell SCv2020's and 2x R630's.  The HP's currently host HyperV VM's stored on local storage, my plan is to use the SCv2020's to store the VM's and make them available to the R630's so I can live migrate between hosts.

Having not used this type of device before I was thinking that I would use a group of SSD's for HyperV and then the slower 10K HDD's for general file sharing.  Which it still looks like I can do, but I'm not sure this would make best use of it.

Having setup one of the SCv's for testing the default setup has grouped all the storage in to one large junk (7xSSD, 7x10K's) where I was expecting to have to specify what I wanted.  So my question is could I create a 1.5TB volume for HyperV and another 5TB volume for general file storage and leave the SCv to decide which disks are better suited to which task based on access?  Or something along these lines.

Thanks in advance.
