To address space constraints on a Nutanix Files instance in a cluster where compression is already enabled and data cannot be deleted, the administrator should useSmart Tiering. Smart Tiering, enabled through Nutanix Data Lens, allows the administrator to tier infrequently accessed (cold) data from the Nutanix Files instance to a secondary storage tier, such as a cloud-based object store (e.g., AWS S3), thereby freeing up space on the primary cluster without deleting data.
TheNutanix Unified Storage Administration (NUSA)course explains that “Smart Tiering, managed via Nutanix Data Lens, enables Nutanix Files to offload cold data to a secondary storage tier, such as cloud storage, to alleviate space constraints while maintaining data accessibility.” This feature uses lifecycle policies to identify data that has not been accessed for a specified period and moves it to a cost-effective tier, reducing the storage footprint on the primary cluster.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “Smart Tiering is an effective solution for managing space constraints in Nutanix Files by tiering cold data to external storage, such as AWS S3, while keeping the data accessible to users through a unified namespace.” This approach is ideal for the scenario, as it addresses the space issue without requiring data deletion, and it works even when compression is already enabled.
The other options are incorrect:
Smart DR: Smart DR is a disaster recovery feature for Nutanix Files that replicates data between sites for failover and recovery. It does not reduce space usage on the primary cluster, as it creates a copy of the data on the secondary site.
Object Replication: Object Replication is a feature of Nutanix Objects, not Nutanix Files, and it focuses on replicating object store buckets, not file shares, to another site.
Smart Sync: Smart Sync is not a Nutanix feature; it may refer to third-party tools or unrelated functionalities and is not applicable here.
The NUSA course documentation emphasizes that “Smart Tiering with Nutanix Data Lens provides a seamless way to manage space constraints in Nutanix Files by offloading cold data to secondary storage, ensuring efficient use of primary cluster resources.”
