RAID-DP is a standard Data ONTAP? feature that safeguards your data from double disk failure. Integrated with our WAFL? (Write Anywhere File Layout) file system, RAID-DP gives you data protection plus high performance.
RAID-DP is a Double Parity RAID 6 implementation that prevents data loss when two drives fail.
We integrated RAID-DP with the WAFL file system to ensure that the dedicated parity drives don’t become a performance bottleneck. You get protection plus the performance you need for your most demanding applications.
RAID-DP makes SATA disk an option for your enterprise storage. You can use less-expensive SATA without worrying about data loss, and also lower your storage acquisition costs.
