NetApp HCI Double Helix data protection is a RAID-less data protection solution designed to maintain both data availability and performance regardless of failure condition. Helix data protection is a distributed replication algorithm that spreads at least two redundant copies of data across all drives in the system. This approach allows the system to absorb multiple failures across all levels of the storage solution while ma

If a storage node should go down, NetApp HCI automatically rebuilds redundant data across all remaining nodes in minutes to maintain high availability with minimal impact to performance due to the platforms architecture. The more nodes in the cluster, the faster the activity occurs and the lower the overall impact. No matter where the failure occurs (drive, node, backplane, network or software failure), the recovery process is the same.
