A Storage Administrator is restructuring the QoS policies for a multi-tenant service provider environment hosted on an HPE Primera array. The architect wants to ensure strict performance SLAs are met for all premium tenants while preventing the array from becoming oversubscribed.
[Proposed QoS Policy Configuration]
Total Array Capacity Limit: 100,000 IOPS (Based on sizing)
Tenant A (Premium): Min IOPS = 40,000
Tenant B (Premium): Min IOPS = 40,000
Tenant C (Premium): Min IOPS = 30,000
Tenant D (Standard): Min IOPS = NONE, Max IOPS = 10,000
Which TWO architectural anti-patterns will result from implementing this specific QoS configuration? (Choose 2.)

• A. The configuration will fail validation because QoS policies are restricted to managing bandwidth (MB/s) and cannot be applied directly to IOPS metrics on HPE Primera arrays
• B. During periods of heavy utilization, the array controllers will be forced to arbitrary throttle one or more Premium tenants, causing them to breach their guaranteed 40,000 IOPS SLAs
• C. The combined Minimum IOPS guarantees (110,000) mathematically exceed the physical capabilities of the array (100,000), creating an impossible SLA scenario during peak contention
• D. Tenant D's configuration violates multi-tenancy design because Standard tier workloads must strictly utilize fixed latency targets rather than IOPS caps
• E. Setting the Max IOPS limit for Tenant D to exactly 10,000 will permanently disable the array's automated tiering engine for that specific volume set

A Data Protection Specialist is configuring multi-tenant QoS policies using the HPE Alletra CLI.
The goal is to strictly throttle a "noisy neighbor" DevTest environment to protect the mission- critical Prod environment.
[Proposed QoS CLI Configuration]
Target Workload: DevTest_Tenant (Consists of 50 individual volumes)
Protected Workload: Prod_Tenant (Consists of 20 individual volumes)
Constraint: Ensure DevTest never consumes more than 15,000 IOPS combined.
Which THREE architectural principles must the specialist apply when implementing these QoS policies to ensure success without causing systemic oversubscription? (Select all that apply.)

• A. Setting a Minimum IOPS guarantee on the Prod_Tenant Volume Set ensures that during severe global controller saturation, the array will preferentially delay the DevTest I/O to mathematically protect the guaranteed performance floor of the Prod workload
• B. The storage arrays require the host servers to utilize specialized NVMe-oF Host Bus Adapters to interpret the QoS throttling flags; standard Fibre Channel HBAs will ignore the limits
• C. When configuring Minimum IOPS guarantees for critical workloads, the specialist must ensure the sum of all configured minimums never exceeds the realistically sustainable physical performance capability of the underlying storage media to prevent an unresolvable SLA breach
• D. The specialist must immediately disable the array's inline deduplication engine, as inline cryptographic hashing algorithms calculate I/O at unpredictable intervals that inherently violate strict QoS IOPS caps
• E. The QoS maximum limits (Max IOPS) should be applied to the Volume Set (VVset) containing all
  50 DevTest volumes, rather than applying individual 300 IOPS limits to each volume, to allow dynamic resource sharing among the DevTest servers while enforcing the aggregate 15,000 IOPS ceiling

A Cloud Storage Operations Analyst is investigating an InfoSight wellness alert for an HPE Primera array. The customer reports that their nightly batch processing jobs are taking twice as long as normal, though no hardware has failed.
[InfoSight Wellness Alert - Performance Anomaly]
Array: Primera_Prod_DC1
Symptom: Read Latency Deviation
Normal Baseline: 1.5ms
Current 7-Day Average: 8.5ms
Signature Match: "Noisy Neighbor Contention - Snapshot Over-retention"
Root Cause Detail: Volume 'Dev_DB_Clone' has 45 unexpired snapshots spanning 60 days, causing severe metadata fragmentation and backend read penalties on the shared disk group.
Which TWO actions should the analyst recommend based on this proactive telemetry diagnostic?
(Choose 2.)

• A. Disable the HPE InfoSight telemetry agent on the Primera array to stop the continuous background scanning that is causing the read latency spikes
• B. Provision additional host bus adapters (HBAs) to the servers running the nightly batch processing jobs to force the I/O through the bottleneck faster
• C. Execute a mass deletion of the outdated snapshots on the 'Dev_DB_Clone' volume to immediately relieve the metadata fragmentation and restore read performance
• D. Implement an automated snapshot retention policy that strictly expires and purges Dev/Test clones after a maximum of 7 days to prevent future recurrence
• E. Immediately replace the backend physical disk drives in the affected disk group, as 8.5ms latency proves mechanical platter degradation

A Storage Procurement Specialist is reviewing an HPE InfoSight wellness report for a recently deployed entry-level all-NVMe storage array. The customer purchased top-tier PCIe Gen4 NVMe drives (rated at 7,000 MB/s read throughput), but the array is capping out at half that speed per drive.
[InfoSight Wellness Report - Hardware Bottleneck]
Component: Drive Enclosure 01, Slots 1-12
Drive Type: 3.84TB U.2 NVMe SSD (PCIe Gen4 x4)
Observed Peak Drive Throughput: ~3,400 MB/s per drive
Root Cause: Backplane Interface Negotiation Downgrade
Based on the telemetry provided, what is the specific architectural hardware limitation causing the drives to operate at half their rated throughput?

• A. The U.2 NVMe drives are configured in a single-port mode, immediately halving their available throughput to the storage controllers
• B. The array's internal drive backplane is only physically wired or negotiated for PCIe Gen3, restricting the Gen4 x4 drives to a maximum theoretical bandwidth of roughly 4 GB/s
• C. The storage array's internal SAS expander is artificially throttling the NVMe drives to match the
  12Gbps speed limit of the adjacent legacy SAS drives
• D. The drives lack the mandatory Advanced Data Services E-LTU license required to unlock the full Gen4 PCIe bandwidth capabilities
