Hewlett-Packard's OpenVMS operating system supports RAID 1. The mirrored disks, called a "shadow set", can be in different locations to assist in disaster recovery. Apple's macOS and macOS Server natively support RAID 0, RAID 1, and RAID 1+0, which can be created with Disk Utility or its command-line interface, while RAID 4 and RAID 5 can only be created using the third-party software SoftRAID by OWC, with the driver for SoftRAID access natively included since macOS 13.3. FreeBSD supports RAID 0, RAID 1, RAID 3, and RAID 5, and all nestings via GEOM modules and ccd. Linux's md supports RAID 0, RAID 1, RAID 4, RAID 5, RAID 6, and all nestings. Certain reshaping/resizing/expanding operations are also supported. Microsoft Windows supports RAID 0, RAID 1, and RAID 5 using various software implementations. Logical Disk Manager, introduced with Windows 2000, allows for the creation of RAID 0, RAID 1, and RAID 5 volumes by using dynamic disks, but this was limited only to professional and server editions of Windows until the release of Windows 8. Windows XP can be modified to unlock support for RAID 0, 1, and 5. Windows 8 and Windows Server 2012 introduced a RAID-like feature known as Storage Spaces, which also allows users to specify mirroring, parity, or no redundancy on a folder-by-folder basis. These options are similar to RAID 1 and RAID 5, but are implemented at a higher abstraction level. NetBSD supports RAID 0, 1, 4, and 5 via its software implementation, named RAIDframe. OpenBSD supports RAID 0, 1 and 5 via its software implementation, named softraid.
