At the prices I've seen tossed about, one could purchase twice as many drives and use vinum in a simple mirrored mode. Or better yet, buy a RAID-5 module from Greg Lehey? About 6 months ago when I last looked, big bad 7 or 9 bay SCSI boxes with dual redundant power supplies were under $600US. Or $300 with a single power supply. Add a couple of Adaptec 2940U2W's for $300 each. Or maybe the dual version is available? These days a new MB with built-in Adaptec controller(s) is about the same price as an Adaptec PCI card. Another $200 to be covered with SCSI cables and terminators. Kingston removable trays are about $200 per drive (get the hot swap version, or is this needed or available for LVD?). Kingston is good stuff but expensive, others are less but of unknown quality. You can do without removable trays if you can schedule downtime to replace the bad drive. -- David Kelly N4HHE, dkelly@nospam.hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
