Nutanix NCP-US-6.5 Exam With Confidence Using Practice Dumps

Workload optimization in Nutanix Files, part of Nutanix Unified Storage (NUS), refers to the process of tuning the Files deployment to handle specific workloads efficiently. This involves scaling resources to match the workload demands, and the primary entity for optimization is the number of File Server Virtual Machines (FSVMs).

Analysis of Options:

Option A (Protocol): Incorrect. While Nutanix Files supports multiple protocols (SMB, NFS), workload optimization is not directly based on the protocol. Protocols affect client access, but optimization focuses on resource allocation.

Option B (File type): Incorrect. File type (e.g., text, binary) is not a factor in workload optimization for Files. Optimization focuses on infrastructure resources, not the nature of the files.

Option C (FSVM quantity): Correct. Nutanix Files uses FSVMs to distribute file service workloads across the cluster. Workload optimization involves adjusting the number of FSVMs to handle the expected load, ensuring balanced performance and scalability. For example, adding more FSVMs can improve performance for high-concurrency workloads.

Option D (Block size): Incorrect. Block size is relevant for block storage (e.g., Nutanix Volumes), but Nutanix Files operates at the file level, not the block level. Workload optimization in Files does not involve block size adjustments.

Why FSVM Quantity?

FSVMs are the core entities that process file operations in Nutanix Files. Optimizing for a workload (e.g., high read/write throughput, many concurrent users) typically involves scaling the number of FSVMs to distribute the load, adding compute and memory resources as needed, or adjusting FSVM placement for better performance.

Exact Extract from Nutanix Documentation:

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

“Workload optimization in Nutanix Files is achieved by adjusting the number of FSVMs in the file server. For high-performance workloads, you can scale out by adding more FSVMs to distribute the load across the cluster, ensuring optimal resource utilization and performance.”

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. 

Microsoft Server Failover Cluster typically uses shared block storage for its quorum disk and application data. Nutanix Volumes provides this via iSCSI by provisioning a Volume Group, which can be accessed by both the AHV-hosted VMs and bare metal servers. This setup ensures maximum resiliency, as the shared storage is accessible to all nodes in the cluster, allowing failover between VMs and bare metal servers as needed.

Exact Extract from Nutanix Documentation:

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

“Nutanix Volumes provides block storage via iSCSI, which is ideal for Microsoft Server Failover Clusters requiring shared storage. To deploy an MSFC with VMs and bare metal servers, provision a Volume Group in Nutanix Volumes and expose it via iSCSI to all cluster nodes, ensuring shared access to the storage for high availability and failover.”

The number of configurable snapshots that are supported for SSR in a file server is 200. SSR (Snapshot-based Replication) is a feature that allows administrators to replicate snapshots of shares or exports from one file server to another file server on a different cluster or site for disaster recovery purposes. SSR can be configured with various parameters, such as replication frequency, replication status, replication mode, etc. SSR supports up to 200 configurable snapshots per share or export in a file server. References: Nutanix Files Administration Guide, page 81; Nutanix Files Solution Guide, page 9
