The Simulator for VM Rightsizing Card Deck in HPE CloudPhysics evaluates actual VM utilization against provisioned resources. It identifies under- and overprovisioned VMs, providing insights into reclaimable resources and accurate sizing recommendations. This directly helps plan server and storage upgrades.

Distractors:

A: Storage Space Management focuses on datastore usage trends, not provisioning mismatches.

B: Reclaimable VMware vDisk Space identifies unused storage, not CPU/RAM sizing.

D: Infrastructure Planning helps plan new builds but doesn't directly analyze current over/under provisioning.

Key Concept: VM Rightsizing = CloudPhysics tool for over/under provisioning analysis.

Rationale for Correct Answe r:

For HPC and AI/ML workloads, NFS over RDMA (Remote Direct Memory Access) provides significantly lower latency and reduced CPU overhead compared to standard NFS over TCP. This allows direct memory-to-memory data transfers between storage and compute nodes, bypassing the kernel network stack. In VAST Data (underpinning GreenLake for File Storage), NFS over RDMA is explicitly supported to accelerate shared dataset access in HPC and AI environments.

Distractors:

A: Standard NFS introduces more latency due to kernel TCP/IP stack overhead.

C: RoCE (RDMA over Converged Ethernet) is a transport layer technology --- useful, but the protocol chosen for the file system must be NFS over RDMA, not just RoCE.

D: iSER (iSCSI Extensions for RDMA) enhances iSCSI block storage, not NFS file workloads.

Key Concept: NFS over RDMA for HPC/AI shared datasets.

For competitive or 3rd-party (non-HPE) environments like Dell + VMware, HPE CloudPhysics is the correct tool. The Observer VM is deployed into vCenter to gather real-world workload metrics (CPU, memory, storage I/O). These analytics can then be used for SimpliVity HCI sizing.

Distractors:

A: NinjaOnline SimpliVity Sizer requires input metrics, but it cannot directly collect from 3rd-party environments.

B: InfoSight sizing applies to HPE arrays, not competitive storage.

D: InfoSight for SimpliVity only monitors existing HPE SimpliVity clusters.

Key Concept: CloudPhysics Observer gathers competitive workload metrics feeds into SimpliVity sizing.

Rationale for Correct Answe r:

The SAF (Storage Assessment Framework) requires engineers to manually email the collected assessment data to HPE for processing. This is different from fully automated tools like CloudPhysics or Backup assessments that integrate directly with portals. This distinction is important for new engineers performing customer assessments.

Distractors:

A: Backup assessments are usually tool-driven (StoreOnce, RMC, etc.) and automated.

C: Non-HPE assessments are outside scope and not part of HPE standard process.

D: CloudPhysics is fully automated and cloud-based --- no manual email required.

Key Concept: SAF = requires manual email submission to HPE.
