HP HPE2-K45 Dumps Questions Answers

The best way to migrate virtual machines from the existing infrastructure to HPE SimpliVity is to share HPE SimpliVity datastores with standard ESXi hosts, and migrate the virtual machines using VMware vSphere® Storage vMotion®1. This method allows the virtual machines to be moved to the HPE SimpliVity datastores without any downtime or impact on the performance. The HPE SimpliVity datastores are automatically created and managed by the HPE SimpliVity Virtual Controller, and they can be shared with any ESXi host that is in the same vCenter Server® as the HPE SimpliVity cluster2. Connecting VMFS datastores holding the virtual machine files to HPE SimpliVity nodes, and migrating the virtual machines (option A) is not a supported method, as the HPE SimpliVity nodes do not have direct access to the VMFS datastores, and they can only use the HPE SimpliVity datastores3. Mapping VMFS datastores holding the virtual machine files as an RDM to HPE SimpliVity nodes, and migrating the virtual machines (option C) is not a supported method, as the HPE SimpliVity nodes do not support RDM devices, and they can only use the HPE SimpliVity datastores4. Adding ESXi system to the HPE SimpliVity cluster, and migrating the virtual machines to HPE SimpliVity datastores (option D) is not a recommended method, as it requires the ESXi system to be converted to an HPE SimpliVity node, which involves installing the HPE OmniStack software and the HPE SimpliVity Virtual Controller, and reconfiguring the network settings. This method may cause downtime and data loss, and it is only advised for specific scenarios, such as replacing a failed node or expanding the cluster. References:

The correct answer is A. All VMs on the node restart in a node where the replica resides. This is because HPE SimpliVity uses a replication factor (RF) of 2 or 3 to ensure that each virtual machine (VM) has one or two copies of its data on different nodes in the cluster. If an HPE OmniStack Virtual Controller (VC) fails, the VMs on that node lose access to their primary data, but they can still access their replica data on another node. The vSphere HA feature detects the VC failure and restarts the VMs on the node where the replica resides, ensuring data availability and continuity1.

The other options are not correct. Option B is incorrect because HPE SimpliVity Intelligent Workload Optimizer (IWO) is a feature that balances the VMs across the cluster based on CPU and memory utilization, not on VC failures2. Option C is incorrect because the IP address of the VC does not fail over to another node, but remains associated with the failed node. The VMs on the failed node are restarted on another node with a different VC IP address3. Option D is incorrect because the VMs on the node do not go on standby mode, but are restarted on another node to resume their operations.

The Persistent Storage layer is the lowest layer of the HPE SimpliVity Data Visualization Platform. It is responsible for storing and tracking all data and metadata on the HPE SimpliVity nodes. It uses a distributed file system that spans across all nodes in a cluster, and provides high availability, scalability, and performance. The Persistent Storage layer also integrates with the HPE OmniStack Accelerator Card, which enables accelerated data efficiency, global unified management, and built-in data protection12. References: HPE SimpliVity Data Virtualization Platform technical white paper, SimpliVity Data Virtualization Platform Architecture - YouTube
