BlueXP tiering is a service that extends your data center to the cloud by automatically tiering inactive data from on-premises ONTAP clusters to object storage. This frees valuable space on the cluster for more workloads, without making changes to the application layer. BlueXP tiering can reduce costs in your data center and enables you to switch from a CAPEX model to an OPEX model. BlueXP tiering leverages the capabilities of FabricPool, which is a NetApp Data Fabric technology that enables automated tiering of data to low-cost object storage. Active (hot) data remains on the local tier (on-premises ONTAP aggregates), while inactive (cold) data is moved to the cloud tier — all while preserving ONTAP data efficiencies12. References = Learn about BlueXP tiering, Cloud Tiering: Free up Space on On-Premises Storage Systems

 The provision role is a predefined role for cluster administrators that allows them to create and manage storage resources, such as aggregates, volumes, LUNs, and qtrees. It also allows them to configure and manage networking resources, such as interfaces, ports, routes, and subnets. The provision role has access to all commands under the “storage” and “network” command directories1. References = Predefined roles for cluster administrators - NetApp

= The ONTAP Mediator service and the MetroCluster TieBreaker are two NetApp features that can be used to automate switchover in a MetroCluster IP configuration in the event of a site disaster. The ONTAP Mediator service is a software component that monitors the health and connectivity of the MetroCluster nodes and initiates a switchover when it detects a failure of one site or a network partition between the sites. The MetroCluster TieBreaker is a software component that runs on a third site and acts as a quorum witness for the MetroCluster configuration. The MetroCluster TieBreaker prevents split-brain scenarios and enables automatic switchover when one site becomes unavailable or isolated. References = ONTAP Mediator service overview, [MetroCluster TieBreaker overview], Data protection with automatic unplanned switchover in two-node MetroCluster configurations

 NetApp Storage Encryption (NSE) and NVMe self-encrypting drives (SED) are two NetApp products that offer hardware encryption. Hardware encryption is a method of encrypting data at the disk level using a hardware-accelerated mechanism. NSE requires all drives in an HA pair to be purpose-built, self-encrypting drives. These drives perform the data encryption themselves through a hardware-accelerated mechanism. Because of the hardware acceleration, NSE systems usually outperform NVE systems when encrypting data1. NVMe self-encrypting drives (SED) are a type of NSE drives that use the NVMe protocol to provide high performance and low latency. NVMe SEDs are supported on select NetApp AFF systems2. References = Configure NetApp hardware-based encryption overview, Netapp Encrypts Data at Rest and in Transit, Which hardware platforms support software-based encryption (NVE and NAE …, How does NVE and NAE encrypt data? - NetApp Knowledge Base

= 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.

 NetApp BlueXP backup and recovery supports various object storage services as backup destinations, including IBM Cloud Object Storage and Microsoft Azure Blob.

BlueXP backup and recovery also supports Amazon S3, Google Cloud Storage, NetApp StorageGRID, and NetApp ONTAP S3 as backup destinations. References = BlueXP backup and recovery documentation, Back up on-premises ONTAP to IBM Cloud Object Storage, Back up on-premises ONTAP to Azure Blob

= NetApp Aggregate Encryption (NAE) and NetApp Volume Encryption (NVE) are software-based encryption solutions that protect data at rest on a per-aggregate or per-volume basis, respectively. They use AES 256-bit encryption and support both internal and external key management. They do not require self-encrypting drives (SEDs) or NetApp Storage Encryption (NSE), which are hardware-based encryption solutions that use FIPS 140-2 level 2 validated drives. Onboard Key Manager (OKM) is a built-in tool that serves authentication keys to nodes from the same storage system as the data, but it is not an encryption mechanism by itself. References = NetApp Volume Encryption, Configure NetApp Volume Encryption overview, Storage Encryption & Disk Encryption – Self Encrypting Software | NetApp, How to configure OKM for NVE & Where to Get Encryption Key - NetApp …

 = When provisioning SAN, the host owns the file system. A LUN is a logical unit of storage that is presented to the host as a SCSI device. The host can format the LUN with any file system it supports, such as NTFS, ext4, or XFS. The ONTAP software does not manage the file system on the LUN, but only provides the block-level access to the LUN. The volume is a logical container for one or more LUNs, but it does not own the file system either. References = SAN Concepts, LUNs and Volumes
