I'm not quite clear what the differences are. The following basic descripitons are from www.lemis.com Plex organizations The manner in which data is mapped to a plex has a significant effect on the utility of the plex. Vinum offers three mappings: concatenated plexes use the complete address space of each subdisk in turn. A striped plex conforms to RAID 0. The address space is taken from each subdisk in turn in stripes of a specified size. This makes for more even loading in many cases. A RAID 5 plex incorporates error recovery: if each subdisk is located on a different physical drive, the plex can continue operation even if any single drive involved in the plex fails. -- Laurence Berland, Stuyvesant HS Debate <><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><><> Windows 98: n. useless extension to a minor patch release for 32-bit extensions and a graphical shell for a 16-bit patch to an 8-bit operating system originally coded for a 4-bit microprocessor, written by a 2-bit company that can't stand for 1 bit of competition. http://stuy.debate.net icq #7434346 aol imer E1101 To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
