The Escalade Storage Switch gives you a choice of four RAID con-
figurations. Select one.
• Stripe (RAID 0): maximizes performance and capacity through a
process called striping. High performance arrays write portions
of a single file across multiple drives. There is no fault tolerance.
• Mirror (RAID 1): duplicates or “mirrors” the data on both
drives. No data will be lost if one of the drives fails.
• RAID 10: combines mirroring and striping, providing both fault
tolerance and high performance. RAID 10 arrays require a
minimum of four drives. Configurations consist of 4, 6 or 8
drives.
• RAID 5: combines parity data and striping, providing fault toler-
ance, high capacity and high storage efficiency. The parity data
is distributed across all drives, rather than being concentrated on
