NEW QUESTION # 54
An HPE Partner is sizing an Alletra MP B10000 array for a customer using the HPE Ninja Sizer online tool.
When tuning the solution, the partner is not getting the best read and write performance from the array.
Use your cursor to place a + where the partner can click in the web GUI to begin to determine how to correct this Issue and appropriately size the solution for the customer.
Answer:
Explanation:
Explanation:
Performance Estimation
The HPE Ninja Sizer is a vital tool for storage architects to model the "Performance vs. Capacity" trade-offs of the HPE Alletra MP B10000 disaggregated architecture. In this scenario, the current configuration (as shown in the exhibit) consists of 4 nodes and 1 JBOF (with 8 drives of 15.36TB each).
To address poor read/write performance in Ninja Sizer, the partner must analyze the Performance Estimation pane. By clicking the chart/graph icon in the bottom right of the summary dashboard, the tool opens a detailed breakdown of the IOPS, throughput, and latency limits for the selected hardware. In a disaggregated shared-everything (DASE) architecture like the Alletra MP, performance is a direct function of the "node-to- drive" ratio. A configuration with only 8 drives (as seen in image_6491d0.png) may be "disk-bound," meaning the controllers have more compute power than the backend drive count can support in parallel.
By accessing the performance details, the partner can see if the bottleneck is at the node level (CPU/Cores) or the drive level (Flash bandwidth). To "correct this issue" and optimize the sizing, the partner would typically need to increase the drive count within the JBOF to allow for more parallel I/O streams or add additional JBOFs to scale the backend bandwidth. The Ninja Sizer provides real-time feedback; as the partner adds more
15.36TB drives, they will see the Performance Estimation bars move from yellow/red toward green, indicating an appropriately balanced solution that meets the customer's latency and throughput SLAs.
NEW QUESTION # 55
A customer wants to encrypt all drives without noticeable performance impact. Which option should be recommended?
Answer: A
Explanation:
Self-Encrypting Drives perform encryption directly in hardware, minimizing performance overhead while protecting data at rest. Software-based methods may impact CPU performance. Jumbo frames and LACP address networking, not encryption.
NEW QUESTION # 56
A storage administrator wants to set up NAS replication between two HPE StoreOnce appliances. A corresponding NAS library was created between the two systems, primary and secondary, where the secondary will receive the replicated information. When the administrator tries to create the NAS mapping on the primary StoreOnce solution, the administrator is presented with an error stating they do not have permission. What should the administrator do to solve this issue?
Answer: B
Explanation:
In the context of HPE StoreOnce Catalyst and NAS replication, security is governed by a bi-directional trust or permission-based handshake. When configuring replication between two StoreOnce appliances, the
"Target" (Secondary) system acts as the gatekeeper. The error described occurs because the primary system is attempting to push data or create a mapping to a destination that has not authorized it.
According to the HPE StoreOnce documentation regarding Replication Permissions, the secondary appliance must explicitly grant permission to the source appliance before any mapping or data transfer can occur. This is a security measure designed to prevent unauthorized data ingestion or "rogue" replication tasks from consuming storage resources on the target system. To resolve the permission error, the administrator must log into the Secondary StoreOnce appliance (the target) and navigate to the replication settings. There, they must add the Primary StoreOnce appliance as an authorized "source" by specifying its network address (FQDN or IP) and providing the necessary credentials (username and password) that the primary system will use to authenticate.
Unlike simpler protocols where a "Public Access" setting (Option B) might exist, HPE StoreOnce requires a defined relationship for NAS and Catalyst replication to ensure data integrity and multi-tenancy security.
Option A refers to token-based authentication, which is more common in modern cloud-native Alletra environments via DSCC, but not the standard for legacy StoreOnce NAS replication. Options D is incorrect because the permission must be granted at the receiving end, not the sending end. Once the secondary system has the primary's details stored in its Replication Permissions list, the primary appliance will be able to successfully "discover" the target libraries and establish the mapping without further permission errors.
NEW QUESTION # 57
A customer wants predictive analytics to identify storage issues before users notice them. Which HPE feature delivers this capability?
Answer: A
Explanation:
HPE InfoSight uses AI-driven predictive analytics to identify anomalies, recommend remediation, and prevent outages proactively. iLO manages servers, SSH provides remote access, and REST APIs allow automation but do not provide predictive intelligence.
