Nutanix Files, part of Nutanix Unified Storage (NUS), uses File Server Virtual Machines (FSVMs) to manage file services. A four-node FSVM deployment means four FSVMs are deployed, typically one per node in a four-node cluster. Nutanix Files requires two networks for FSVMs:
* Client Network: Used for client-facing communication (e.g., SMB, NFS access).
* Storage Network: Used for internal communication with the Nutanix cluster's storage pool.
Each FSVM requires one IP address on each network, as established in Question 1.
Analysis of Options:
* Option A (Four available IP addresses on the Client network): Correct. In a four-node FSVM deployment, each FSVM requires one IP address on the Client network for client communication (e.g., SMB, NFS). With four FSVMs, this means four IP addresses are needed on the Client network, one for each FSVM.
* Option B (Four available IP addresses on the Storage network): Correct. Each FSVM also requires one IP address on the Storage network for internal communication with the Nutanix cluster's storage pool. For four FSVMs, this means four IP addresses are needed on the Storage network, one for each FSVM.
* Option C (Five available IP addresses on the Storage network): Incorrect. Only four IP addresses are needed on the Storage network for a four-node FSVM deployment-one per FSVM. A fifth IP address is not required, as there is no additional entity (e.g., a virtual IP) needed for the Storage network in this context.
* Option D (Five available IP addresses on the Client network): Incorrect. Similarly, only four IP addresses are needed on the Client network for the four FSVMs. A fifth IP address might be needed in other scenarios (e.g., a virtual IP for load balancing in some configurations), but for a standard four- node FSVM deployment, four IPs suffice, as established in Question 1.
Selected Requirements:
* A: Four IP addresses on the Client network are required, one for each of the four FSVMs.
* B: Four IP addresses on the Storage network are required, one for each of the four FSVMs.
Why These Requirements?
Each FSVM in a Nutanix Files deployment requires one IP address on the Client network for client access and one on the Storage network for internal storage communication. For a four-node FSVM deployment, this translates to exactly four IP addresses on each network, matching the number of FSVMs.
