In the Video, Creating A Storage Space Pool in Windows Server 2012 R2 Essentials Preview, I show how to create a pool with three relatively small hard drive. From that pool I show how to create three 1TB virtual hard disk drives (“HDDs”). Each had different levels of resiliency:
- Simple Resiliency (essentially no resiliency and much like a RAID0)
- 2-Way Mirror Resiliency
- Parity Resiliency
Figure 2 shows the Physical and Logical view of how Storage Spaces works and how it was demonstrated in the video.
Figure 2 -- A Storage Spaces Pool will be created from three physical 150GB HDD's and from that three 1TB Virtual HDD's will be Created
After the Storage Spaces Pool is set up and the Virtual HDDs are created I measured the performance of each Virtual HDD. Before I created the Storage Spaces Pool I had measured the performance of each of the 3 HDDs that would make up the Pool to have a reference to compare to the Virtual HDDs performance.
