= Dynamic Disk Pools (DDP) is a disk layout type that provides the fastest rebuild time after disk failure on an E-Series system. DDP distributes data, parity, and spare capacity across a pool of disks, instead of using dedicated parity and spare disks. This enables faster and more efficient reconstruction of data in the event of a disk failure, as well as better performance and load balancing. DDP also reduces the risk of data loss due to multiple disk failures, as it can tolerate any number of disk failures up to the pool’s protection level. References = SANtricity OS Dynamic Disk Pools | TR-4652 - NetApp, How to increase priority for disk reconstruction - NetApp Knowledge Base.

 FPolicy is an ONTAP feature that enables this functionality. FPolicy is a file access notification framework that allows external applications to monitor and control file access on ONTAP storage systems1. FPolicy can be used to protect files from ransomware by integrating with third-party solutions that use user behavioral analytics (UBA) to detect abnormal activity andtrigger actions such as creating a Snapshot copy and blocking the AD user access23. FPolicy can also be activated with a single click from BlueXP or ONTAP System Manager to protect against common ransomware extensions4. References = 1: FPolicy overview - NetApp, 2: Prevent ransomware spread with ONTAP automatic ransomware protection, 3: Fighting Ransomware, Part Six: Remediation, 4: Proactive ransomware protection—automated with ONTAP - NetApp.

 FabricPool is an ONTAP feature that tiers inactive data to an object store such as StorageGRID. StorageGRID uses erasure coding to protect data by slicing an object into data fragments and parity fragments, and spreading them across Storage Nodes. To use erasure coding, the storage pool must include three or more sites, or exactly one site. Two sites are not supported. Therefore, the minimum number of sites required to deploy the StorageGRID solution with FabricPool and erasure coding is three. References = Configuring StorageGRID for FabricPool, What erasure-coding schemes are

S3 Object Lock helps you to meet regulatory compliance, privacy, and data protection requirements for your object data. References = Manage objects with S3 Object Lock, Example 7: Compliant ILM policy for S3 Object Lock, NetApp StorageGRID ILM on tape

= Intercluster LIFs are logical interfaces that enable communication between clusters for data replication and caching. The minimum number of intercluster LIFs required on a cluster depends on the number of nodes, the number of IPSpaces, and the network topology. According to the NetApp documentation, the following are the requirements for intercluster LIFs:

• At least one intercluster LIF must be configured on every node in the local cluster, and on every node in the remote cluster. Provisioning intercluster LIFs on only some nodes of the cluster is not supported.
• Each intercluster LIF requires an IP address dedicated for intercluster communication. The IP addresses assigned to intercluster LIFs can reside in the same subnet as data LIFs or in a different subnet.
• Every intercluster LIF on every node of the local cluster should be able to connect to every intercluster LIF on every node of the remote cluster. The cluster peering topology should use full-mesh connectivity. Full-mesh connectivity means that all the Intercluster LIFs of one peer cluster can communicate with all of the Intercluster LIFs of the other peer cluster.

Based on these requirements, the minimum number of intercluster LIFs required on a 4-node cluster is 8, assuming that there is only one IPspace and a full-mesh network topology. This means that each node has one intercluster LIF that can connect to the intercluster LIFs of the other nodes in the same cluster and the remote cluster. If thereare more IPSpaces or a different network topology, the number of intercluster LIFs may vary. References = What is an Intercluster network?, Create intercluster LIFs (Beginning with ONTAP 9.3), Create intercluster interfaces on all nodes (ONTAP 9.2 or earlier)
