32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Cluster quorum

A cluster requires a majority of nodes to be online for quorum; with an even node count, a tiebreaker (mediator or quorum device) breaks ties. Loss of quorum makes the cluster read-only until quorum is restored.

HA pair takeover

In an HA pair, each node monitors its partner. If a node fails, the partner takes over its LIFs and aggregates, keeping data available. Storage failover show verifies takeover readiness.

Cluster LIF

A logical interface on each node that carries intra-cluster traffic such as cluster peering, SnapMirror, and volume moves. Cluster LIFs are not used by clients and must exist on every node.

Node management LIF

The IP address used to administer a node via SSH, ONTAP System Manager, or the ONTAP REST API. It is separate from data LIFs, which serve client traffic on SVMs.

SVM data LIF

A client-facing IP address hosted on an SVM. It has a home node and port and fails over to a partner according to its failover policy, such as system-defined or local-only.

Broadcast domain

A group of ports that share a Layer 2 network. It provides the port pool for creating LIFs and must contain at least one port. IPspaces isolate broadcast domains between SVMs.

IPspace

A network namespace within a cluster. SVMs in different IPspaces can reuse the same IP subnets without conflict, which is useful for multi-tenant environments.

RAID-DP

ONTAP's double-parity RAID, the default for HDD aggregates. It tolerates two simultaneous disk failures and requires at least three disks; a spare disk is needed for reconstruction.

FlexVol volume

A logical container that holds files or LUNs within an aggregate. With guarantee none, it can be thin-provisioned and overcommit aggregate space. Volume show lists size and available space.

FlexGroup volume

A scale-out volume that spans multiple nodes in a cluster. It provides higher capacity and performance than a FlexVol and is created with volume create -style flexgroup.

Qtree

A partition of a FlexVol volume used for quota and security boundaries. Qtrees are created with volume qtree create and listed with volume qtree show.

Snapshot copy

A point-in-time, space-efficient copy of a volume. The snapshot policy defines schedule and retention, and snapshot show lists snapshots per volume.

SnapMirror relationship

A replication link between a source and destination volume or SVM. Its policy (Mirror, Vault, or MirrorAndVault) and type (DP or XDP) define what is replicated and retained.

SnapMirror lag time

The time since the last successful transfer. Snapmirror show displays lag time and last transfer status; high lag indicates replication is behind schedule.

SnapMirror policy

A named set of rules that controls which snapshots are replicated and how long they are retained. Mirror replicates snapshots; Vault retains them; MirrorAndVault does both.

SnapVault relationship

A backup relationship (type XDP, policy Vault) that retains snapshots on the destination for long-term recovery. It is created with snapmirror create -type XDP -policy Vault.

Cloud Backup

An ONTAP feature that sends volume backups to object storage such as AWS S3 or Azure Blob. It is managed via BlueXP or ONTAP System Manager and is distinct from FabricPool tiering.

FabricPool tiering

A tiering policy on an aggregate that moves cold data to object storage. It is configured with storage aggregate object-store create and is not a backup relationship.

SnapMirror Cloud

A replication type that sends ONTAP volume data to object storage. It uses a cloud policy and is verified with snapmirror show and the cloud provider console.

RBAC in ONTAP

Role-based access control assigns roles such as admin, operator, or readonly to users. Security login show lists login methods, roles, and applications for each user.

SVM security style

The permission model enforced on an SVM: unix uses mode bits, ntfs uses NTFS ACLs, and mixed uses both. The style determines which permissions apply to files.

NFS export policy

A set of rules that controls client access to NFS exports. Each rule specifies a client match, access type (ro or rw), and root access. Export-policy rule show lists rules.

NetApp Volume Encryption

NVE encrypts data at rest on a per-volume basis. It is verified with volume show -fields encryption; NAE applies encryption at the aggregate level instead.

ONTAP statistics command

The CLI tool for performance metrics. Statistics show -object volume -instance <vol> -counter read_ops,write_ops,latency displays per-volume metrics for troubleshooting.

QoS policy group

A group that limits or protects workload performance. It is created with qos policy-group create and monitored with qos statistics show, which displays policy-group performance.

EMS event log

ONTAP's event management system log. Event log show lists events; event catalog show explains definitions. Filter with event log show -severity error to find problems.

AutoSupport

A telemetry feature that sends health and configuration data to NetApp. It is verified with system node autosupport show and feeds Active IQ risk recommendations.

Automated Upgrade

ONTAP's rolling upgrade process that keeps the cluster available. Cluster image show lists images; system node image update updates a node; cluster image validate checks compatibility.

ONTAP REST API

An HTTPS/JSON automation interface. Use /api/version to check supported versions and /api/private/cli for CLI-equivalent endpoints. Authenticate with basic or certificate auth.

BlueXP

NetApp's cloud management console for on-premises and cloud ONTAP. It manages Cloud Volumes ONTAP, Cloud Backup, and FabricPool, and reports backup lag and errors.

Cloud Volumes ONTAP

ONTAP running in a public cloud such as AWS, Azure, or GCP. It is managed through BlueXP and verified with the cloud provider console and cluster show.

Volume move

A nondisruptive operation that relocates a volume to another aggregate. It is started with volume move start and monitored with volume move show; the destination needs free space.
