The mappings are +implemented in runtime loadable plugins called +mapping targets. + +These mappings can be used to support +arbitrary software RAID solutions on Linux +2.6, such as ATARAID, without the need to have +a special low-level driver as it used to be +with Linux 2.4. This avoids code-redundancy +and reduces error rates. + +Device-mapper runtime mappings (eg, map sector +N of a mapped device onto sector M of another +device) are defined in mapping tables. + +The dmraid application is capable of creating +these for a variety of ATARAID solutions (eg. +Highpoint, NVidia, Promise, VIA). It uses an +abstracted representation of RAID devices and +RAID sets internally to keep properties such +as paths, sizes, offsets into devices and +layout types (e.g., RAID0). RAID sets can be of +arbitrary hierarchical depth in order to +reflect more complex RAID configurations such +as RAID10. + +Because the various vendor specific metadata +formats stored onto ATA devices by the ATARAID +BIOS are all different, metadata format +handlers are used to translate between the +ondisk representation and the internal +abstracted format. + +The mapping tables which need to be loaded +into device-mapper managed devices are derived +from the internal abstracted format. + +My talk will give a device-mapper +architecture/feature overview and elaborate on +the dmraid architecture and how it uses the +device-mapper features to enable access to +ATARAID devices. + + diff --git a/2005/flow-accounting-ols2005/OLS2005/mauelshagen/mauelshagen.tex b/2005/flow-accounting-ols2005/OLS2005/mauelshagen/mauelshagen.tex new file mode 100644 index 0000000..e457e3c --- /dev/null +++ b/2005/flow-accounting-ols2005/OLS2005/mauelshagen/mauelshagen.tex @@ -0,0 +1,100 @@ +% The file must begin with this \documentclass declaration.
