Create Disk Array Display, RAID 5 ExampleSelect RAID configurationThe Escalade ATA RAID Controller gives you a choice of fourRAID configurations. Select one.• Stripe (RAID 0): maximizes performance and capacity through aprocess called striping. High performance arrays write portionsof a single file across multiple drives. There is no fault tolerance.• Mirror (RAID 1): duplicates or “mirrors” the data on bothdrives. No data will be lost if one of the drives fails.• RAID 10: combines mirroring and striping, providing both faulttolerance and high performance. RAID 10 arrays require aminimum of four drives. Configurations consist of 4, 6, 8, 10or 12 drives.• RAID 5: combines parity data and striping, providing fault toler-ance, high capacity and high storage efficiency. The parity datais distributed across all drives, rather than being concentrated onC r e a t e D i s k A r r a yHelpAlt-F1 Change ValueEnterPrevious/NextNote: Creating an array will overwrite existing data on its drives.Create a disk array from these drives:Port 1 - IBM-DTLA-387815 512 MPort 2 - IBM-DTLA-387815 512 MPort 3 - IBM-DTLA-387815 512 MSelect RAID Configuration:Array's Write Cache State: enableCancelOKCancelEscStripe Size: 64 KBRAID 5
