Windows Server 2012 Storage space Disk Check

How do I check how many disks in the storage pool are being consumed by virtual disks in the storage space?

In Windows Server 2012, storage space refers to striped data that is written to the underlying physical disk. Interleaving represents the amount of data written per column of the stripe. For example, by default, the amount of interleaved data is 256KB.

This means that a virtual disk in the storage pool is divided into 5 column values stored in five physical disks, a staggered 256KB stripe, then the stripe width is 256kb*5 (that is, single make data) equals 1280KB.

This is not important, if the virtual disk is using mirroring, parity, and those columns are being used, the total disk usage will always display the column value. But when you use mirroring and parity, the stripe width value will include both the effect and the mirrored data, so it can reflect the actual data written, like these parity/mirror blocks are included in the stripe area.

Here we can use a few methods to check. It is recommended that you use Windows PowerShell commands. Note that you can see the interleaved value, the NumberOfColumns value, and the Resiliencysettingname value in the Paritylayout value that I'm using in the parity option.
