Storage recommendations for DPM 2016

I am looking for deploying DPM 2016 and want to use StarWind VTL for tape backups like described in this blog:

The problem is that I do not know what storage would be best for DPM 2016.

My backup server has PERC H330 controller with 6x2TB 7.2K SAS disks and 4X800GB SSDs. Basically, I have several options: configure RAID5, RAID6 or Storage Spaces with tiering, like it was proposed here. I searched a lot for advice but want to know more thoughts and arguments for the best solution.

Any advice is appreciated.

Solution 1:

You can absolutely build tiered Storage Spaces with your spinners + flash! In this case hot backups will stay on-site within fastest possible tier (flash initially, offloaded to disks after flash filled with data 100% <- this process is controlled by Windows Storage Spaces' mechanism), and cold backups will find their way to off-site public cloud after threshold value & conditions met <- this one is controller by VTL itself.
