Geom Raid5

Geom Raid5

geom_raid5 is a storage module created for the FreeBSD operating system. It facilitates RAID5 functionality without the need of a hardware RAID controller.

geom_raid5 allows storage of large amounts of data to be protected against disk failure, while providing good throughput performance. Like other FreeBSD storage modules, geom_raid5 utilizes the GEOM framework. It is built as a kernel loadable module (KLD) which allows it to run inside the FreeBSD kernel. The module can be compiled on FreeBSD release 5 and newer releases. geom_raid5 is also incorporated into FreeNAS, an Operating System dedicated to Network Attached Storage. Its author, Arne Woerner, has released the software under the BSD license, making geom_raid5 OSI-compliant open source software.
