Hello folks,
I am happy to share with you that Microsoft just released Storage Spaces Design Consideration Guide and Software-Defined Storage Design Calculator.
Storage Spaces Design Consideration
The Software-Defined Storage Design Calculator (SDS) spreadsheet is to design a storage solution that uses the Storage Spaces and Scale-Out File Server functionality based on Windows Server 2012 R2 along with cost-effective servers and shared serial-attached SCSI (SAS) storage enclosures (JBODs).

This spreadsheet combines prescriptive design workflow and computation with deployment and configuration best practices, empowering users to design a resilient and high-performance software-defined storage solution. The spreadsheet leverages preconfigured solution templates (including small, medium, and large-scale deployments) which can then be adjusted to match specific solution requirements and available hardware available from a Storage Spaces solution vendor.


For detailed information about the Storage Spaces design best practices this spreadsheet uses, see the Software-Defined Storage Design Considerations Guide.
And for background info about Storage Spaces, see the Storage Spaces Overview.
Enjoy!
Cheers,
@Charbel
