Also, becausedata is duplicated on both drives, a RAID level 1 configuration using two 120-GB hard drivescollectively has a maximum of 120 GB on which to store data.Configuring Your Computer for RAIDAt some point you may want to configure your computer for RAID if you did not select a RAIDconfiguration when you purchased your computer. You must have at least two hard drivesinstalled in your computer to set up a RAID configuration. For instructions on how to install ahard drive, see page 95.You can use one of two methods to configure RAID hard drive volumes. One method uses theIntel® RAID Option ROM utility and is performed before you install the operating system ontothe hard drive. The second method uses the Intel Matrix Storage Manager, or Intel MatrixStorage Console, and this method is performed after you have installed the operating systemand the Intel Matrix Storage Console. Both methods require that you set your computer toRAID-enabled mode before starting any of the RAID configuration procedures in thisdocument.Setting Your Computer to RAID-Enabled Mode1 Enter system setup (see page 128).2 Press the up- and down-arrow keys to highlight Drives, and press .3 Press the up- and down-arrow keys to highlight SATA Operation, and press .hard drive 1segment 1segment 2segment 3hard drive 2segment 4segment 5segment 6segment 1 duplicatedsegment 2 duplicatedsegment 3 duplicatedsegment 4 duplicatedsegment 5 duplicatedsegment 6 duplicatedserial ATA RAIDconfigured forRAID level 1D8659bk0.book Page 20 Thursday, March 10, 2005 10:18 AM
