Nutanix Updated NCP-US-6.5 Exam Questions and Answers by matias

Volumes is a feature that allows users to create and manage block storage devices (volume groups) on a Nutanix cluster. Volume groups can be accessed by external hosts using the iSCSI protocol. To ensure maximum performance, throughput, and redundancy for Oracle RAC on Linux implementation, while using the native method for securing workloads, the recommended configuration is to use Volumes with MPIO (Multipath I/O) and a single vDisk (virtual disk). MPIO is a technique that allows multiple paths between an iSCSI initiator and an iSCSI target, which improves performance and availability. A single vDisk is a logical unit number (LUN) that can be assigned to multiple hosts in a volume group, which simplifies management and reduces overhead. References: Nutanix Volumes Administration Guide, page 13; Nutanix Volumes Best Practices Guide

Data Lens is a feature that provides insights into the data stored in Files across multiple sites, including different geographical locations. Data Lens allows administrators to monitor usage, performance, capacity, and growth trends for all Files deployments globally. Data Lens also provides reports on file types, sizes, owners, permissions, and access patterns3.

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. References: Nutanix Files Administration Guide, page 33; Nutanix Files Solution Guide, page 8

A single-node cluster cannot support a Distributed Share because it can only host one FSVM, whereas Distributed Shares require at least three FSVMs for distribution and high availability. This limitation causes the “Use Distributed Share/Export type instead of Standard” option to be absent when creating a share, as the cluster does not meet the minimum requirements.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“Distributed Shares require a minimum of three FSVMs to ensure scalability and high availability, which typically requires a cluster with at least three nodes. On a single-node cluster, only Standard Shares are supported, and the option to create a Distributed Share will not be available in the Files Console.”

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. References: Nutanix Files Administration Guide2
