RAID-1 in the strict definition has two disks with the same data. In the modern loose definition it means two or more disks with the same data (maybe 3 disks). There is an option of whether reads go to all disks in a RAID-1 set or to just one disk. Some OSs (such as AIX) make this a tunable. In Linux there is no option, reads go to one disk. So if two programs make read requests at the same time with a software RAID-1 on Linux then (ideally) each disk will receive one request and the result will be that the two requests are satisfied in less time than it would take on a single disk. -- http://www.coker.com.au/selinux/ My NSA Security Enhanced Linux packages http://www.coker.com.au/bonnie++/ Bonnie++ hard drive benchmark http://www.coker.com.au/postal/ Postal SMTP/POP benchmark http://www.coker.com.au/~russell/ My home page -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
