= 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.

A hypervisor is a software layer that enables multiple operating systems to run on the same physical hardware by creating virtual machines (VMs) that are isolated from each other. A hypervisor abstracts the operating system from the underlying hardware, allowing for greater flexibility, efficiency, and scalability of the virtualized environment. NetApp supports several hypervisor platforms, such as VMware ESXi, KVM, and Hyper-V, and provides storage solutions that integrate with them. References = Storage virtualization overview, VMware hypervisor and hardware considerations, NetApp HCI Resources

= A Kubernetes cluster is a group of machines that run containerized applications as part of a distributed system. A Kubernetes cluster consists of two types of nodes: worker nodes and master nodes. Worker nodes are the machines that run the actual workloads, such as pods, which are groups of containers. Master nodes are the machines that run the control plane, which is responsible for managing the cluster state, scheduling workloads, and enforcing policies. A cluster must have at least one master node and one or more worker nodes. A cluster can also have multiple master nodes for high availability and load balancing. References = What is Kubernetes Cluster?, Kubernetes Nodes - The Complete Guide, Nodes | Kubernetes

Advanced Disk Partitioning (ADP) is a feature that enables ONTAP to partition a disk into multiple logical units and use them for different purposes. ADP has two main benefits for AFF or FAS systems:

• It optimizes storage capacity by reducing the number of disks required for the root aggregates, which store the system and configuration data. By using ADP, the root aggregate can share the same disk with a data aggregate, which stores the user data. This frees up more disks for data aggregates and increases the usable space for data.
• It reduces RAID parity overhead by creating smaller RAID groups with partitions instead of whole disks. This reduces the amount of parity data that needs to be written and read, which improves the performance and efficiency of the system. References = What are the rules for Advanced Disk Partitioning?, Considerations for automatic drive assignment and ADP systems in ONTAP 9.4 and later, NetApp AFF and Advanced Drive Partition v2, part 1
