HPE2-T37 Questions and Answers

When utilizing 25Gb connectivity for all HPE Synergy compute nodes, the maximum number of frames that can form a single logical enclosure is 3. This limitation is due to the bandwidth and port constraints associated with 25Gb interconnect modules. Logical enclosures define the management and networking domains within the Synergy infrastructure, and adhering to these limits ensures optimal performance and reliability.

A key characteristic of the RoCE (RDMA over Converged Ethernet) network type is that it must be a tagged network. RoCE requires VLAN tagging to segregate traffic and ensure proper delivery of RDMA services over Ethernet networks. Tagging facilitates the identification and handling of RoCE traffic by the network infrastructure.

Option C (Correct): RoCE networks require VLAN tagging to function correctly.

Option A: Quality of Service (QoS) is important for performance but is not enabled by default.

Option B: RoCE networks are not inherently private; they can be configured according to requirements.

Option D: Smart Link is not necessarily enabled for RoCE networks by default.

In HPE OneView, you can configure the iLO Federation Group parameter using a server profile. This setting allows you to assign the server's iLO to a specific federation group, enabling features like group power control and firmware updates across multiple servers. By configuring this parameter within the server profile, you ensure consistent iLO settings across all servers that use that profile.

Option A (Correct): iLO Federation Group can be set in the server profile to organize iLOs into groups for collective management.

Option B: The iLO firmware repository is managed separately and is not configured via server profiles.

Option C: Active Directory integration is a global setting configured at the appliance level, not per server profile.

Option D: Access to the remote console is managed via iLO user permissions, not directly through server profiles.

Your customer can obtain the PowerShell Library for HPE OneView by downloading it from the Microsoft PowerShell Gallery. The library is publicly available and can be installed using standard PowerShell commands. This allows users to automate and script HPE OneView operations, enhancing efficiency and integration with existing workflows.

Installation Command:

Install-Module -Name HPOneView.XXX

(Replace 'XXX' with the specific version number)

If the desired CPG (Common Provisioning Group) is not available when creating a volume in HPE OneView, you should verify that the CPG was imported as a managed storage pool. In HPE OneView:

Managed Storage Pools: Only storage pools (CPGs) that have been imported and are managed by HPE OneView will be available for provisioning volumes.

Importing Storage Pools: You need to manually import the specific CPG as a managed storage pool within HPE OneView to make it selectable during volume creation.

Steps to Resolve:

Navigate to Storage Systems in HPE OneView.

Select the HPE Primera array in question.

Go to Storage Pools and verify if the CPG is listed.

If not, use the Add Storage Pool option to import the CPG as a managed pool.

The HPE OneView appliance can be deployed to KVM, in addition to VMware ESXi and Microsoft Hyper-V. HPE provides support for deploying the OneView virtual appliance on KVM hypervisors, allowing customers with KVM environments to use OneView for managing their infrastructure.

Option A (Correct): KVM is a supported hypervisor for HPE OneView appliance deployment.

Option B: Incorrect, as KVM is supported.

Option C/D: Workarounds like nested virtualization are unnecessary since KVM is supported.

From the HPE OneView interface, you can grow a volume provisioned on an external array. This action allows administrators to increase the capacity of existing volumes to meet growing storage requirements without disrupting services. The ability to grow volumes is contingent on the support of the underlying storage system and available capacity.

To visualize the rack system and the Aruba top-of-rack switches in HPE OneView, the customer should define the switches as unmanaged devices manually. By adding the Aruba switches as unmanaged devices, they become part of the rack layout within HPE OneView, allowing for a comprehensive visual representation of the physical infrastructure.

Option A (Correct): Manually adding switches as unmanaged devices includes them in rack visualizations.

Option B: HPE OneView does not automatically discover and add third-party switches via hardware discovery.

Option C: Unless specifically supported, Aruba switches cannot be added as managed devices.

Option D: Monitored devices require SNMP support and integration, which may not be available for these switches.

The server profile template feature available only for HPE Synergy compute nodes is the Firmware and drivers update options integrated with the HPE Image Streamer. This allows for:

Stateless Computing: Deploy both firmware and operating system images rapidly.

Driver Management: Simultaneous management of firmware and drivers through server profiles.

Unique to HPE Synergy:

HPE Image Streamer: Exclusive to HPE Synergy, enabling deployment of OS images along with firmware updates.

Enhanced Server Profiles: Include the ability to define the complete software stack in the server profile template.

When the HPE OneView appliance is rebooted or offline, it does not affect the managed resources. Servers, storage systems, and networking devices continue to operate normally. The appliance serves as a management interface, and its availability is not required for the ongoing operation of the infrastructure. However, management tasks cannot be performed until the appliance is back online.

Option A: The appliance being offline does not impact network or storage traffic.

Option B: Servers are not placed into maintenance mode automatically.

Option D: The iLO processors remain accessible directly; the appliance's status does not affect iLO accessibility.

Networks

To configure Quality of Service (QoS) on HPE Synergy frames equipped with HPE Virtual Connect SE 700Gb F32 Modules, you use the Logical Interconnect Group in HPE OneView. The Logical Interconnect Group (LIG) serves as a template that defines the networking configurations for interconnect modules, including QoS settings, network uplinks, and stacking.

Option B (Correct): QoS settings are defined within the Logical Interconnect Group, ensuring consistent network configurations across multiple enclosures.

Option A: Fabric Manager is not an HPE OneView object used for this purpose.

Option C: Logical Enclosure represents a collection of enclosures but does not define QoS settings.

Option D: Enclosure Group defines the physical configuration but not the network-specific QoS settings.

Virtual Connect will pass through all tagged packets without modification, and it will be the responsibility of the teaming software to strip/add tags.
