HPE Storage Architect Sample Questions:

1. A Storage Architect is evaluating an HPE GreenLake for File Storage deployment supporting a genomics research environment.
Requirements:
12 PB dataset
Linux compute nodes
POSIX semantics
Multi-GB/s throughput
Minimal application modification
Which THREE statements accurately support the recommended architecture? (Choose 3.)

A) Fibre Channel storage is mandatory for all workloads exceeding one petabyte
B) NFS over RDMA can provide POSIX-compliant access while reducing traditional networking overhead
C) RDMA-capable networking can improve throughput efficiency and reduce CPU consumption
D) Object storage APIs are required for POSIX-compliant applications
E) Existing applications can continue utilizing standard file system interfaces

2. A Storage Administrator proposes the following QoS configuration.
Array Sustainable Performance: 180,000 IOPS
Configured Minimum Guarantees:
Oracle RAC: 75,000
SAP HANA: 60,000
SQL Production: 55,000
VDI: 30,000
Which THREE conclusions are valid? (Choose 3.)

A) The QoS design should be revised before implementation
B) Thin provisioning compensates for oversubscribed performance guarantees
C) The array automatically creates additional performance resources during saturation events
D) SLA violations may occur during periods of contention
E) Configured minimum guarantees exceed sustainable platform capability

3. An Infrastructure Capacity Planner is forecasting the 3-year growth for an environment backed by an HPE Alletra 5000 hybrid array.
[Growth Forecast Requirements]
Requirement 1: Database random read I/O will increase by 40% next year (Compute/Cache bound).
Requirement 2: Archive file storage capacity will increase by 200 TB next year (Disk bound).
What is the fundamental architectural advantage of the Alletra 5000/6000 "Scale-to-Fit" design when addressing these highly asymmetrical growth requirements, compared to a traditional monolithic or hyperconverged scale-out architecture?

A) It requires the planner to mathematically balance the CPU-to-Disk ratio, mandating that for every
200 TB of capacity added, a new pair of symmetrically matched controller nodes must be purchased
B) The architecture automatically virtualizes the connected host RAM to satisfy Requirement 1, relying solely on standard JBOD enclosures to satisfy Requirement 2
C) It allows non-disruptive, independent scaling of compute (upgrading the controller heads), read cache (installing more SSDs), or total capacity (adding HDD expansion shelves) precisely matching the specific bottleneck without forcing unnecessary hardware purchases
D) The array relies on a dedicated Storage Area Network (SAN) routing protocol to migrate active workloads to older, retired storage arrays, avoiding physical expansion entirely

4. A Customer Success Manager is reviewing a Data Ops Manager dashboard with a client. The client is confused because the dashboard shows a massive discrepancy between two capacity metrics on their HPE Alletra array.
[Data Ops Manager - Capacity Overview]
Total Logical Space Provisioned: 150 TB
Total Physical Space Consumed: 25 TB
The client asks: "If I have provisioned 150 TB of volumes to my VMware hosts, how is it physically possible that the array only shows 25 TB of actual disk space being used?" Which core architectural feature of modern HPE storage arrays natively creates this mathematical discrepancy, and how should the Customer Success Manager explain it?

A) The VMware ESXi hosts have crashed and temporarily lost their Fibre Channel zoning, causing the array to logically unmount the volumes and report the physical space as unconsumed
B) The array utilizes background automated tiering, moving 125 TB of cold data to an external S3 object bucket that is not tracked by the local Data Ops Manager dashboard
C) The array uses Thin Provisioning and Inline Data Reduction (Deduplication and Compression); the hosts believe they have 150 TB of space (Logical), but because the data is highly compressible, deduplicated, and largely empty (zeroes), it only occupies 25 TB of actual flash media (Physical)
D) The Data Ops Manager only displays physical capacity consumed by the active array controller (Node 0); the remaining 125 TB is safely stored on the standby controller (Node 1) and will not appear in the dashboard until a failover occurs

5. A Storage Architect is reviewing a proposed QoS design.
Array Sustainable Performance:
160,000 IOPS
Configured Minimum Guarantees:
Oracle RAC: 70,000
SAP HANA: 50,000
SQL Production: 45,000
VDI: 25,000
Which THREE conclusions are correct? (Choose 3.)

A) The QoS design should be revised before implementation
B) Thin provisioning compensates for oversubscribed performance guarantees
C) The configured guarantees exceed sustainable platform capability
D) The storage platform automatically creates additional performance resources during saturation events
E) SLA violations may occur during periods of contention
