Storage Spaces is a feature found in Windows and Windows Server designed to safeguard your data against hard drive failures. It operates similarly to RAID but is developed as a software solution. With Storage Spaces, you can combine three or more drives into a single storage pool, from which you can allocate capacity to create individual Storage Spaces. These spaces typically maintain multiple copies of your data, ensuring that if one drive fails, you still have a secure version of your information. When you find yourself lacking storage capacity, you can easily incorporate additional drives into the existing storage pool. There are four primary implementations of Storage Spaces: on a standard Windows PC, on a stand-alone server with all the storage contained within that server, on a clustered server using Storage Spaces Direct with local storage connected directly to each cluster node, and on a clustered server that utilizes one or more shared SAS storage enclosures encompassing all the drives. This versatility makes it suitable for expanding volumes on Azure Stack HCI and clusters running Windows Server, allowing for flexible and resilient data management. By leveraging these various configurations, users can effectively tailor their storage solutions to meet specific needs.
