NetApp BlueXP observability pricing model is based on the number of managed units (MUs) that you wish to monitor. A managed unit is a logical grouping of resources that can be monitored by Cloud Insights, such as a virtual machine, a Kubernetes pod, a storage volume, or a database instance. The number of managed units is not bound to specific device types, giving you the flexibility to re-deploy in line with your business and infrastructure needs. You can choose from different subscription plans based on the number of managed units and the duration of the contract.

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.

FlexCache is a NetApp technology that will enable the company to prepopulate a subset of the data from their remote factories to their AI Center of Excellence. FlexCache is a feature of NetApp ONTAP that allows you to create a cache volume on a local or remote cluster and populate it with data from a source volume on another cluster. FlexCache enables faster access to data by reducing latency and network bandwidth consumption. FlexCache also allows you to select a subset of data from the source volume to cache, based on your business needs. FlexCache can be used for various use cases, such as AI and machine learning, where you need to access a subset of data from a large data lake for training or inference.

Active IQ Unified Manager is a tool that enables you to define the performance and storage objectives for a workload using Performance Service Levels (PSLs). You can assign a PSL to a workload when initially creating the workload, or afterwards by editing the workload. The management and monitoring of storage resources are based on Service Level Objectives (SLOs), which are defined by service level agreements that are based on required performance and capacity. Active IQ Unified Manager provides a few predefined PSLs, such as Extreme Performance, Performance, and Value, and also allows you to create your own PSLs to meet your needs. You can also apply the PSLs to multiple clusters and workloads to ensure optimal performance and utilization of the underlying resources.

To activate the destination volume for data access, you must quiesce and break the SnapMirror relationship. Quiescing disables future SnapMirror data transfers, and breaking makes the destination volume read-write. This allows you to use the destination volume for disaster recovery purposes.
