[music] In this video, we will learn a little bit about RAID triple eraser coding, also called RAID tech, which [music] is part of ONAP 9. This feature provides some great benefits. It improves system resiliency up to 100 times against drive failures. It handles up to three simultaneous [music] failures per ray group, and it is based on NetApp patented technology. As a reminder, the RAID technology built into [music] ONAP protects your system against numerous types of disk errors such as bad blocks, lost rights, misdirected rights, and complete [music] disc failures. Now, let's do a simulation of RAID tech. ONTAP stores par information on separate par drives in a RAID group. In this 19 drive simulated rate group, we see par blocks being calculated and stored. This happens automatically as part of every [music] write operation. Rate tech adds anti-dagonal par to the previously existing par types. Let's take a look at one of the [music] most difficult situations. Three drives simultaneously failing. Immediately after the drives [music] fail, RAID tech kicks in to reconstruct the data on one of the drives. It does this through extremely fast and efficient exor operations. Here we have slowed down the simulation to see some of the intermediate steps. Surviving drives [music] are read once and all recovery calculations are done in memory. At this point, ONAP uses the proven RAID DP technology to restore the data on the remaining two drives. And we see that [music] onap has recovered all of the data intact. Ray is a powerful feature that NetApp has introduced with ONAP 9. Upgrade to ONAP 9 today and start enjoying the benefits of RAID tech.
