問題 #16
A customer needs block storage for SAP HANA requiring certified performance and high availability. Which HPE platform is most suitable?
答案：D
問題 #17
Refer to the exhibit.
A company is implementing a disaster recovery solution. The Asynchronous Remote Copy feature has been implemented between the HPE AUetra 9000 arrays at both sites. The customer Is interested in providing a disaster recovery (DR) solution that allows for business connectivity of their VMware VMs.
Which VMware solution should the company implement?
答案：D
解題說明：
To provide automated orchestration and business continuity for VMware virtual machines in a disaster recovery scenario, the industry-standard solution integrated with HPE storage is VMware Live Site Recovery (formerly known as VMware Site Recovery Manager or SRM).
When a customer utilizes Asynchronous Remote Copy on HPE Alletra 9000 arrays, the storage layer handles the data replication between the production and recovery sites. However, the storage array alone cannot automate the re-registration of virtual machines, the mapping of network port groups, or the specific power-on sequencing required for complex applications at the secondary site. VMware Live Site Recovery serves as the orchestration engine that bridges this gap. It works in conjunction with a Storage Replication Adapter (SRA) provided by HPE. The HPE SRA allows the VMware software to communicate directly with the Alletra 9000 arrays to initiate tasks such as promoting recovery volumes to a read-write state, taking temporary snapshots for DR testing, and automating the "failover" and "failback" workflows.
As shown in the exhibit (image_6601ef.jpg), a complete solution requires an SRM appliance and a vCenter appliance at both the production and recovery sites. This architecture ensures that even if the primary site is completely lost, the recovery site has all the necessary metadata and orchestration instructions to bring the business-critical VMs online with minimal manual intervention. Option A (Lifecycle Management) is for patching and updates, Option D (Storage DRS) is for load balancing within a cluster, and Option C refers to operational monitoring rather than disaster recovery orchestration. For a customer already invested in Alletra
9000 Remote Copy, VMware Live Site Recovery is the "Better Together" choice for achieving low Recovery Time Objectives (RTO).
問題 #18
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?
答案：A
解題說明：
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.
問題 #19
A customer has a diverse NoSQL big data and data analytics workload implementation. This workload runs on bare-metal servers to achieve the most efficient performance. The customer requires a new storage solution to meet their growing data needs. Which solution will be best for the customer?
答案：C
解題說明：
For workloads like NoSQL databases (e.g., MongoDB, Cassandra), Big Data analytics (e.g., Hadoop, Spark), and high-throughput data lakes, the primary performance bottleneck is often the latency and bandwidth between the compute and the storage media. When a customer specifies they are running on bare-metal servers to achieve "most efficient performance," they are looking for a solution that minimizes the overhead of hypervisors and provides direct, high-speed access to storage. The HPE Alletra Storage Server 4000 series, and specifically the Alletra 4110, is purposefully engineered for this "Data-First" server-based storage market. The Alletra 4110 is a
1U, all-NVMe ultra-dense storage server that supports dual 4th or 5th Gen Intel Xeon Scalable processors and PCIe Gen5 throughput. Unlike traditional storage arrays that connect via a SAN, the Alletra 4110 functions as high-performance Software-Defined Storage (SDS) infrastructure. It is designed to run the application and the data storage on the same high-density nodes, or to act as a high-speed storage tier for bare-metal clusters.
問題 #20
A customer currently has an HPE Alletra 9000 with data reduction on all volumes and plans to migrate to an HPE Alletra MP B10000. Which formula should be used to size the new solution?
答案：A
解題說明：
When sizing a migration from a highly efficient array like the HPE Alletra 9000 (or Primera) to the next-generation HPE Alletra MP B10000, storage architects must account for the difference between the "Written Capacity" (what the host thinks it has stored) and the "Consumed Capacity" (the physical space used after data reduction).
The standard best practice for an HPE Master ASE when performing these migrations is to Size to consumption multiplied by 1.25. This "1.25 factor" (representing a 25% overhead) is the recommended safety margin used in sizing tools like HPE NinjaStars and the HPE Cloud Physics assessment reports. This 25% buffer is designed to cover several critical architectural requirements:
System Metadata and Overhead: Both the Alletra 9000 and Alletra MP require physical capacity to store internal metadata, map tables, and the structures required for their respective data reduction engines. Snapshot Reserve: While snapshots are thin and pointer-based, they still consume physical space as data changes over time. The 1.25 multiplier ensures there is enough
"headroom" for typical snapshot retention policies.
Data Reduction Parity: Data reduction ratios (deduplication and compression) can fluctuate based on the specific workload. Sizing exactly to current consumption without a buffer risks an out-of- space condition if the new array's reduction engine handles a specific block pattern slightly differently during the initial ingest.
Operational Performance: SSD-based arrays perform best when they are not "packed" to 100% capacity, as the garbage collection and wear-leveling processes require free blocks to operate efficiently.
