Actual exam question for Nutanix's NCP-MCI-6.5 exam
Question #: 24
Topic #: 4
[All NCP-MCI-6.5 Questions]

An administrator needs to deploy an application with a large amount of data connected via Nutanix volumes.

Which two actions should the administrator take when designing the Volume Group? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: A, B

According to the Nutanix Volumes - Recommendations And Best Practices web search result3, two actions that the administrator should take when designing the Volume Group are:

Distribute workload across multiple virtual disks: Use multiple disks rather than a single large disk for an application. Consider using a minimum of one disk per Nutanix node to distribute the workload across all nodes in a cluster. Multiple disks per Nutanix node may also improve an application's performance. For performance-intensive environments, we recommend using between four and eight disks per CVM for a given workload.

Enable RSS (Receive Side Scaling): Receive-side scaling (RSS) allows the system to use multiple CPUs for network activity. With RSS enabled, multiple CPU cores process network traffic, preventing a single CPU core from becoming a bottleneck. Enabling RSS within hosts can be beneficial for heavy iSCSI workloads. For VMs running in ESXi environments, RSS requires VMXNET3 VNICs. For Hyper-V environments, enable VMQ to take full advantage of Virtual RSS.

Using multiple subnets for iSCSI traffic could also help in optimizing data transfer.

I also believe enabling thick provisioning on the Volume Group(s) is important for performance.

Yes, that would help balance the data load effectively.

I think we should distribute workload across multiple virtual disks.
