 .Sh HISTORY
 RAIDframe is a framework for rapid prototyping of RAID structures
 developed by the folks at the Parallel Data Laboratory at Carnegie
 Mellon University (CMU).
 A more complete description of the internals and functionality of
 RAIDframe is found in the paper "RAIDframe: A Rapid Prototyping Tool
 for RAID Systems", by William V. Courtright II, Garth Gibson, Mark
 Holland, LeAnn Neal Reilly, and Jim Zelenka, and published by the
 Parallel Data Laboratory of Carnegie Mellon University.
 .Pp
 RAIDframe was ported to
 .Nx
 by Greg Oster in 1998, who has maintained it since.
 In 1999, component labels, spares, automatic rebuilding of parity, and
 autoconfiguration of volumes were added.
 In 2000, root on RAID support was added (initially, with no support for
 loading kernels from RAID volumes, which has been added to many ports since.)
 In 2009, support for parity bimap was added, reducing parity resync time
 after a crash.
 In 2010, support for larger the 2TiB and non-512 sector devices was added.
 In 2018, support for 32-bit userland compatibility was added.
 In 2021, support for autoconfiguration from other-endian raid sets was added.
 .Pp
 Support for loading kernels from RAID 1 partitions was added for the
 alpha, pmax and vax ports in 2000, the the sgimips port in 2001,
 the x86 ports in 2003, the arc port in 2005, the landisk, sparc, and
 sparc64 ports in 2006, the cobalt port in 2007, the ofppc port in 2008,
 the bebox port in 2010, the emips port in 2011, and the sandpoint port
 in 2012.
 .Pp
 The
 .Nm
 command first appeared as a program in CMU's RAIDframe v1.1 distribution.
 This version of
 .Nm
 is a complete re-write, and first appeared in
 .Nx 1.4 .
