NetApp® RAID-DP® technology, a standard feature of the Data ONTAP® operating system, is a double-parity RAID 6 implementation that prevents data loss when two drives fail.
We integrated RAID-DP with the WAFL® (Write Anywhere File Layout) file system to ensure that the dedicated parity drives don't become a performance bottleneck. You get data protection plus the performance you need for your most demanding applications.
RAID-DP makes SATA disks an option for your enterprise storage. You can use less-expensive SATA disks without worrying about data loss, while lowering your data storage acquisition costs and boosting your storage efficiency.
Create your foundation for storage resiliency with RAID-DP technology. Get the implementation details: NetApp Implementation of RAID-DP for Data Protection PDF (PDF).
