A mirror space also stripes the data across multiple physical drives. Increases reliability, but reduces capacity. Stores two or three copies of the data across the set of physical disks Suited for high-performance workloads where resiliency is not required or is already provided by the application. Use to host temporary or easily recreated data at a reduced cost. Simple spaces do not protect against disk failure. No resiliency (does not protect from disk failure)ĭo not use to host irreplaceable data. Maximizes disk capacity and increases throughput To plan for the number of physical disks and the desired resiliency type for a stand-alone server deployment, use the following guidelines. If the EnclosureNumber and SlotNumber fields contain values, then the enclosure supports these features. To determine whether the JBOD enclosure supports enclosure and slot identification, run the following Windows PowerShell cmdlet: If you're using a JBOD enclosure, verify with your storage vendor that the enclosure supports Storage Spaces to ensure full functionality Recommended to use Storage Spaces certified enclosures listed on the Windows Server Catalog Storage Spaces is compatible only with HBAs where you can completely disable all RAID functionality. This includes enclosure services that are provided by attached just-a-bunch-of-disks (JBOD) devices. Adapters must not abstract the physical disks, cache data, or obscure any attached devices. If RAID-capable, HBAs must be in non-RAID mode with all RAID functionality disabled Simple host bus adapters (HBAs) that do not support RAID functionality are recommended Storage Spaces is supported on iSCSI and Fibre Channel (FC) controllers as long as the virtual disks created on top of them are non-resilient (Simple with any number of columns). However, it's not optimal to use USB drives in a server environment. Serial Advanced Technology Attachment (SATA) A failover cluster deployment has different prerequisites, such as supported disk bus types, supported resiliency types, and the required minimum number of disks. If you want to learn how to deploy Storage Spaces on a failover cluster, see Deploy a Storage Spaces cluster on Windows Server 2012 R2. For information about these additional parameters, see New-VirtualDisk and the Windows Server storage forum. Through Windows PowerShell, you can set additional parameters such as the number of columns, the interleave value, and which physical disks in the pool to use. When you create a virtual disk through the File and Storage Services user interface, you can configure the resiliency type (simple, mirror, or parity), the provisioning type (thin or fixed), and the size. A storage space appears to the Windows operating system as a regular disk from which you can create formatted volumes. These virtual disks are also referred to as storage spaces. A storage pool enables storage aggregation, elastic capacity expansion, and delegated administration.įrom a storage pool, you can create one or more virtual disks. A storage pool is a collection of physical disks. To create a storage space, you must first create one or more storage pools. For information about how to create a clustered storage space, see Deploy a Storage Spaces cluster on Windows Server 2012 R2. This topic describes how to deploy Storage Spaces on a stand-alone server. Applies to: Windows Server 2022, Windows Server 2019, Windows Server 2016, Windows Server 2012 R2, Windows Server 2012
