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

The organization is deploying a Nutanix cluster to provide block storage services (via iSCSI), CIFS shares, and NFS exports (via Nutanix Files). Nutanix Volumes, part of Nutanix UnifiedILON Storage (NUS), is used to provide block storage to physical servers via iSCSI. The security policy requires separate networks:
* Management traffic on VLAN 500 (10.10.50.0/24).
* iSCSI traffic on VLAN 510 (10.10.51.0/24).
* Files traffic on VLAN 520 (10.10.52.0/24).
To ensure iSCSI traffic uses VLAN 510 and is accessible by physical servers, the cluster must be configured to route iSCSI traffic over the correct network.
The Data Services IP is the key configuration for iSCSI traffic in a Nutanix cluster. By setting this IP to an address on VLAN 510 (e.g., 10.10.51.x), the administrator ensures that iSCSI traffic is routed over the correct network. Physical servers can then connect to this IP to access block storage via iSCSI. This configuration is done in Prism Element under the cluster's iSCSI settings.
Exact Extract from Nutanix Documentation:
From the Nutanix Volumes Administration Guide (available on the Nutanix Portal):
"To enable iSCSI traffic for Nutanix Volumes, configure the Data Services IP in Prism Element. This IP address is used by external hosts (e.g., physical servers) to connect to the cluster for block storage access.
Assign the Data Services IP to the appropriate VLAN for iSCSI traffic (e.g., VLAN 510) to ensure network isolation and accessibility."

Smart Tiering is a feature that allows Files to tier data across different storage tiers based on the file size and access frequency. Smart Tiering supports files with a minimum size of 64 KiB and a maximum size of 5 TiB2. Reference: Nutanix Files Administration Guide2

Data Lens is a feature that provides insights into the data stored in Files, such as file types, sizes, owners, permissions, and access patterns. Data Lens allows administrators to create reports on various aspects of their data and schedule them to run automatically on a weekly basis. Reference: Nutanix Data Lens Administration Guide

The administrator can achieve this request by deleting and recreating a new Objects store with the updated name. Objects is a feature that allows users to create and manage object storage clusters on a Nutanix cluster.
Objects clusters can provide S3-compatible access to buckets and objects for various applications and users.
Objects clusters can be created and configured in Prism Central. However, once an Objects cluster is created, its name cannot be changed or edited. Therefore, the only way to change the name of an Objects cluster is to delete the existing cluster and create a new cluster with the updated name.
