Applies To: Windows Server 2012 Essentials, Windows Server 2012 R2, Windows Server 2012 R2 Essentials
This topic applies to a server running Windows Server 2012 Essentials or Windows Server 2012 R2 Essentials, or to a server running Windows Server 2012 R2 Standard or Windows Server 2012 R2 Datacenter with the Windows Server Essentials Experience role installed.
Storage Spaces lets you group disks together in a storage pool. You can then use pool capacity to create storage spaces. Storage spaces are virtual drives that appear on the Hard Drives tab of the Dashboard. You can use storage spaces like any other drive, so it’s easy to work with files on them. When you run low on pool capacity, you can create large storage spaces and add more drives to the storage pool. If you have two or more disks within the storage pool, you can create storage spaces with a two-way mirror that won't be affected by a drive failure—or even the failure of two drives, if you create a three-way mirror storage space.
To create a storage space, all you need is one or more extra drives in addition to the drive on which Windows is installed. These drives can be internal or external hard drives, or solid state drives. You can use a variety of types of drives with Storage Spaces, including USB, SATA, and SAS drives. For step-by-step instructions for creating a storage space, see Create a Storage Space.
|If you configure Storage Spaces on a server running Windows Server 2012 Essentials, you cannot perform a Factory Reset with the Clean Data option. The workaround for this issue is to first remove Storage Spaces and then perform a Factory Reset with the Clean Data option.|
