Smart Tier requires access and secret keys to authenticate with the target storage tier, which can be Nutanix Objects or any S3-compatible storage service. The access and secret keys are generated by the target storage service and must be provided when configuring Smart Tier3. Reference: Nutanix Files Administration Guide3

Before upgrading Objects Manager, the administrator must upgrade AOS to the latest version. AOS is the core operating system that runs on each node in a Nutanix cluster and provides the foundation for Objects Manager and Objects service. Upgrading AOS will ensure compatibility and stability for Objects components. Reference: Nutanix Objects Administration Guide, Acropolis Operating System Upgrade Guide

The most likely cause for this issue is that the file server resides on a single node cluster. A distributed share is a type of SMB share or NFS export that distributes the hosting of top-level directories across multiple FSVMs, which improves load balancing and performance. A distributed share cannot be created on a single node cluster, because there is only one FSVM available. A distributed share requires at least two nodes in the cluster to distribute the directories. Therefore, the option to use distributed share/export type instead of standard is not present when creating a share on a single node cluster.

The Data Lens feature that maximizes the available file server space by moving cold data from the file server to an object store is Smart Tier. Smart Tier is a feature that allows administrators to tier data from Files to cloud storage based on file age, file size, and file type. Smart Tier can help reduce the storage cost and optimize the performance of Files. Smart Tier can move cold data, which is data that has not been accessed or modified for a long time, from the file server to an object store, such as AWS Standard or Azure Blob, and free up the file server space for hot data, which is data that is frequently accessed or modified.

The scenario that is causing the alert and needs to be addressed to allow the entities to be protected is that one or more VMs or Volume Groups belonging to the Consistency Group may have been deleted. A Consistency Group is a logical grouping of VMs or Volume Groups that are protected together by a Protection Policy. A Protection Policy is a set of rules that defines how often snapshots are taken, how long they are retained, and where they are replicated for disaster recovery purposes.

If one or more VMs or Volume Groups belonging to the Consistency Group are deleted, the Protection Policy will fail to protect them and generate an alert with the code AI303551 – VolumeGroupProtectionFailed.

The two steps that are required for enabling Data Lens are:

In Prism, enable Pulse health monitoring: Pulse is a feature that collects diagnostic and usage information from Nutanix clusters and services and sends it to Nutanix for analysis and support purposes. Pulse health monitoring is a feature that monitors the health status of Nutanix clusters and services and sends alerts to Nutanix if any issues are detected. To enable Data Lens, Pulse health monitoring must be enabled in Prism Element or Prism Central.

Configure the Data Services IP in Prism Central: Data Services IP is an IP address that is used for communication between Prism Central and Data Lens. Data Services IP must be configured in Prism Central before enabling Data Lens for any file server. Data Services IP must be routable from both Prism Central and Data Lens.

The primary criteria that should be considered for performance-sensitive application shares with sequential I/O is throughput. Throughput is a measure of how much data can be transferred or processed in a given time period. Throughput is usually expressed in megabytes per second (MB/s) or gigabytes per second (GB/s). Sequential I/O is a type of I/O pattern where data is read or written in a sequential order, such as streaming media, backup, or archive applications. Sequential I/O typically requires high throughput to transfer large amounts of data quickly and efficiently. Reference: Nutanix Files Administration Guide, page 25; Nutanix Files Solution Guide, page 10

Nutanix Volumes allows administrators to provision a volume group with one or more volumes that can be attached to multiple VMs or physical servers via iSCSI. This enables the creation of a Microsoft Server Failover Cluster that uses shared storage for a critical application. The volume group can be attached to VMs running on an AHV-hosted cluster and bare metal servers for maximum resiliency1.

The Files Console Dashboard View provides an overview of the Files cluster performance and usage, including the following graphs:

Storage Used: Shows the total storage used by the Files cluster, including data, metadata, and snapshots.

Open Connections: Shows the number of active SMB and NFS connections to the Files cluster.

Number of Files: Shows the number of files stored in the Files cluster, excluding snapshots.

Top Shares by Current Capacity: Shows the top five shares by current capacity usage in the Files cluster.

Top Shares by Current Connections: Shows the top five shares by current connection count in the Files cluster2. Reference: Nutanix Files Administration Guide2
