freebsd operating system it is available in freebsd 5 0 and later releases and provides a standardized way to access storage layers geom is modular and allows for geom modules to connect to the framework for example the geom_mirror module provides raid1 or mirroring functionality to the system a number of modules are provided as part of freebsd and others have been developed independently and are distributed via e g github geom was developed for the freebsd project by poul henning kamp and nai labs the security research division of network associates inc under darpa spawar contract n66001 01 c 8035 cboss as part of the darpa chats research program the name symbolizes its impact on disk geometry stacked design edit because of geom s modular design modules can be stacked together to form a chain of geom layers for example on top of the geom_mirror module an encryption module can be added such as geom_eli to provide a mirrored and encrypted volume each module has both consumers and providers a provider is the source of the geom module often a physical hard drive but sometimes a virtualized disk such as a memory disk the geom module in turn provides an output device other geom modules called consumers can use this provider to create a chain of modules connected to each other source geom module output is referred to as provider geom module consumer s for example the geom_mirror module may use as a consumer the following providers dev ada0 dev ada1 while it creates as a provider a new device called dev mirror gm0 at the end of the geom chain often a filesystem is applied to actually use the geom provider for something useful the provider created by geom modules behaves just like a physical hard drive and as such can contain filesystems such as freebsd s native unix file system ufs available modules edit storage modules 1 geom_stripe raid0 geom_mirror raid1 geom_raid supports raid functionality on software raid controllers geom_raid3 raid3 geom_raid5 raid5 not present in current yet geom_concat concatenating also called spanning or jbod geom_vinum legacy volume manager with raid0 1 4 5 support geom_ccd legacy volume manager with raid0 and rudimentary raid1 support encryption and compression modules geom_eli also called geli provides traditional encryption using aes blowfish triple des or camellia algorithms it can support data authentication using md5 sha1 sha256 sha384 sha512 or ripemd160 geom_bde also called gbde leading edge encryption with four cryptographic barriers geom_shsec shared secret encryption module geom_uzip read only zip compressed images filesystem modules geom_label allows providers to have their own name labeled for easy partitioning geom_journal adds journaling support to the unix file system ufs geom_cache adds caching support for increased performance using ram as buffercache disk partitioning geom_flashmap partition parts of e g flash memory using either offsets or context geom_part supports disk partitioning of geom providers geom_part_apm support apple partition map geom_part_bsd supports bsd disklabel geom_part_bsd64 supports the 64 bit variant of bsd disklabels as used by dragonfly bsd geom_part_ebr supports extended boot record geom_part_gpt supports guid partition table geom_part_ldm supports logical disk manager geom_part_mbr supports master boot record geom_part_vtoc8 supports sun solaris vtoc8 disk labels virtualization geom_mountver enables mount verification geom_multipath support multipath i o to underlying disks geom_nop creates a transparent module used for debugging and testing geom_gate creates a virtual disk using network disk back end geom_virstor allows overloading a geom provider by creating a provider larger than its consumer geom_linux_lvm reads linux lvm2 volumes geom_zero creates a dummy provider that absorbs all writes and returns zeros on reads external links edit rhodes tom geom modular disk transformation framework freebsd handbook kamp poul
