While the greatest focus for Windows Server 2016 Storage Spaces relates to Storage
Spaces Direct, there are other changes outside the improved management through
Server Manager:
The optimization of data between the tiers runs more frequently. In Windows
Server 2012 R2, the optimization runs once a day. In Windows Server 2016, it runs
every four hours, which is visible via the Storage Tiers Optimization scheduled job
trigger properties. This helps the optimization better keep up with workload drift.
Additionally, the optimizer uses prioritization to move the most important data
first (meaning biggest benefit to move between tiers), in case it cannot complete
full optimization in the time allotted.
A new storage health service provides a single point of monitoring for all
components related to Storage Spaces that also automates the recovery processes.Note that Storage Spaces works the same as Windows Server 2012 R2 in terms of
supporting HDD and SSD as the tiers. It is possible to use NVMe with regular Storage
Spaces (but not clustered Storage Spaces, since there is no way to enable shared access
to the PCI Express bus outside of Storage Spaces Direct). However, the NVMe drives
would be treated as one tier, and the other drives as the second tier. For example,
NVMe may make up the performance tier, while SSD makes up the capacity tier.
However, you can’t have a third tier if you have HDDs as well, which is possible in
Storage Spaces Direct; think hottest, hot, and cold data segregation with Storage
Spaces Direct, but just hot and cold with regular Storage Spaces. Additionally, NTFS is
