Storage Spaces is a feature in Windows Server that allows you to group multiple physical drives into a single logical storage pool. This technology offers flexible storage configurations, redundancy, and scalability — making it ideal for businesses of all sizes.
Redundancy: Protects data from drive failure using mirroring or parity.
Scalability: Easily add more drives to the storage pool.
Cost-Effective: Use inexpensive disks to create resilient storage.
Flexibility: Combine different drive types and sizes in one pool.
Click Start > Server Manager.
Navigate to File and Storage Services > Volumes > Storage Pools.
Under Storage Pools, click Tasks > New Storage Pool.
Choose the available physical disks you want to include.
Assign a name and confirm the storage subsystem.
After the pool is created, click Tasks > New Virtual Disk.
Select the storage pool and define:
Storage layout (Simple, Mirror, or Parity)
Provisioning type (Thin or Fixed)
Size of the virtual disk
After creating the virtual disk, proceed to create a volume.
Assign a drive letter and format it with NTFS or ReFS.
Layout | Use Case | Redundancy | Disk Requirement |
---|---|---|---|
Simple | High performance, no redundancy | ❌ | 1 or more |
Mirror | Protect against 1 or more disk failures | ✅ | 2 or more |
Parity | Balanced storage and redundancy | ✅ | 3 or more |
Always use identical or similar drives for better performance.
Monitor disk health with Windows Admin Center or PowerShell.
Keep backups even if redundancy is enabled — Storage Spaces is not a substitute for full backup solutions.
