39. Frage
An administrator wants to build a scale-out solution using two HPE Alletra 6000 storage arrays. Only the first array has been initialized. Use your cursor to place a + where the administrator can add the second uninitialized array to the first storage array.
Antwort:
Begründung:
Explanation:
Hardware
To expand a single-array configuration into a multi-array scale-out cluster (known as an HPE Nimble/Alletra
6000 Group), the administrator must navigate to the physical resource management section of the interface.
In the HPE Alletra 6000 and legacy Nimble Storage UI, this is located under the Hardware tab in the primary navigation menu.
Once the administrator clicks on Hardware, the system displays the "Arrays" view. If a second, uninitialized Alletra 6000 array is physically connected to the same network and has been discovered by the management software (via the Discovery protocol), it will appear in a list of "Discovered Arrays" or within the main hardware pane with an option to be added to the current group. By selecting the uninitialized array and clicking the add/plus icon within that specific Hardware sub-menu, the administrator triggers the group expansion process. This process non-disruptively integrates the new array's controllers and capacity into the existing management plane, allowing for seamless data migration and performance scaling across the member arrays.
The exhibit provided (image_64b359.png) currently shows the Data Protection sub-tab under the Manage menu. This area is dedicated to managing volume collections, snapshots, and replication partners rather than hardware membership. To perform the hardware-level task of adding a new physical node to the cluster, the administrator must first move away from the "Manage" view and select Hardware. This architectural separation ensures that logical data management tasks are distinct from physical infrastructure scaling. Once the second array is added, the "Manage" view will then reflect the combined resources of both arrays, allowing for group-wide volumes that can span the performance and capacity of the entire scale-out solution.

A company is going to upgrade a SAP HANA solution. The company is looking for competitive bids, and only SAP HANA hardware that is certified should be included in a bid. When building the bid, what must you first determine before you can right-size the solution with the appropriate HPE hardware?
Antwort: C
Begründung:
Sizing a storage solution for SAP HANA is fundamentally different from sizing general-purpose virtualization workloads. SAP HANA is an in-memory database, but it has extremely strict requirements for the underlying persistent storage layer to ensure data integrity during savepoints and log writes. SAP enforces these requirements through the SAP HANA Tailored Data Center Integration (TDI) program.
To begin the sizing process and ensure the solution will pass the SAP Hardware Configuration Check Tool (HWCCT) or the newer SAP HANA System Check, a storage architect must first determine the required IOPS rate, specifically for the /hana/data and /hana/log volumes. SAP provides specific KPIs for latency and throughput that must be met. For instance, the log volume requires extremely low-latency writes to handle the sequential redo logs, while the data volume requires high-throughput (MB/s) and specific IOPS to handle asynchronous savepoints.
While the number of nodes (Option C) and replication features (Option D) are important for the overall architecture, they do not dictate the "right-sizing" of the storage performance tier in the same way the IOPS and throughput requirements do. If the storage cannot meet the SAP-certified IOPS and latency thresholds, the entire solution will be unsupported, regardless of how many nodes are present. By identifying the IOPS and throughput needs first, the architect can determine if the customer requires an All-Flash Alletra 9000 or if an Alletra MP configuration with specific drive counts is necessary to provide the required "parallelism" to hit SAP's performance targets.
41. Frage
A customer purchased an HPE GreenLake for File Storage solution and implemented the replication feature.
Which statement is correct regarding this feature?
Antwort: C
Begründung:
HPE GreenLake for File Storage is built upon a disaggregated, shared-everything (DASE) architecture powered by VAST Data software. The replication mechanism in this environment is fundamentally different from traditional block-based replication. Instead of replicating entire volumes or LUNs, HPE GreenLake for File Storage performs replication at the directory level.
According to the HPE GreenLake for File Storage Administrator Guide, the system utilizes a snapshot- based asynchronous replication engine. This allows for highly flexible topologies, including N:1 (fan-in) and
1:N (fan-out) configurations, which are essential for modern distributed data environments and centralized backup strategies. Because the solution is file-based, it leverages "Views" (or shares) that point to specific directory paths. Protection policies and snapshot schedules are applied directly to these paths, ensuring that only the specific datasets required for disaster recovery are replicated.
Option B is a common point of confusion; while the system is inherently "reduction-aware" and uses similarity-based data reduction (deduplication and compression) to save space on the physical media, the replication process itself focuses on the metadata and unique data blocks associated with the directory-level snapshots. Option A is incorrect because, in an asynchronous replication relationship, the destination is typically Read-Only until a failover or clone operation is initiated. Option D is incorrect as the management of protected paths follows strict pairing rules to prevent configuration conflicts. Thus, the support for flexible fan-in/fan-out topologies and granular directory-level protection (Option C) is the defining characteristic of this enterprise file solution.
42. Frage
An administrator needs to create an FCIP trunk connection between two data centers to interconnect their Brocade fibre data fabrics. Refer to the exhibit.
Based on this configuration, which statement is correct?
Antwort: A
Begründung:
In a Brocade FCIP (Fibre Channel over IP) environment, an extension trunk (or tunnel) can be composed of multiple circuits to provide both increased bandwidth and high availability. The operational state of these circuits--whether they are active or standby--is determined by the Metric assigned to each individual circuit.
According to the Brocade Fabric OS Extension Configuration Guide, all circuits within a tunnel or trunk have a metric of either 0 or 1.
Metric 0: This is the default value and indicates an with Metric 0, they will operate in an active- active active circuit. If multiple circuits are configured mode, and the load will be balanced across them. Metric 1: This indicates a standby (or passive) circuit. Standby circuits with Metric 1 are not used for data transmission unless all Metric 0 circuits within that tunnel/failover group fail. In the provided exhibit, there is a single VE_Port (Virtual E_Port) trunking three individual IP circuits:
ge0 is configured with Metric 0 (Active).
ge1 is configured with Metric 0 (Active).
ge2 is configured with Metric 1 (Standby).
Therefore, this is a valid configuration where the system will utilize the two Metric 0 circuits (ge0 and ge1) simultaneously for data traffic, providing an active-active load-balanced connection. The third circuit (ge2) will remain in a standby state, only becoming active to maintain the link if both primary circuits go offline.
43. Frage
A customer is concerned about the long distances between their data centers and significant latencies that might exist between the SAN fabrics at the two data centers. Since SCSI write operations can involve multiple handshake messages between the target and initiator, which Brocade feature should be used to double the recommended distance, but maintain the same latency as a shorter haul link?
Antwort: C
Begründung:
Standard SCSI write operations are inherently sensitive to distance because they require multiple round-trip handshakes before data is actually transmitted. A typical write involves: 1) the Command, 2) a Transfer Ready (XFER_RDY) response from the target, 3) the Data, and 4) the Status. In a long-distance SAN, each of these round trips adds significant "latency wait time," severely degrading performance as distance increases.
To solve this, Brocade (HPE B-series) utilizes a protocol optimization feature known as FastWrite. FastWrite works by creating a Proxy Target (PT) local to the initiator host and a Proxy Initiator (PI) local to the target storage device. When the host issues a SCSI write command, the local Brocade switch (acting as the Proxy Target) immediately sends the XFER_RDY back to the host without waiting for the signal to travel across the long-distance link. This allows the host to send the data segment immediately.
By eliminating the need for every handshake message to traverse the distance multiple times, FastWrite significantly reduces the aggregate latency felt by the application. Architecturally, this enables customers to extend their SAN fabrics over double the distance (and often much further) while maintaining performance comparable to a significantly shorter link. This is critical for asynchronous replication and remote copy applications that issue large I/O blocks. Option C (Write Acceleration) is a generic term often used by other vendors, while FastWrite is the specific, validated Brocade feature name used in HPE Master ASE documentation for this protocol optimization.
