HPE2-K45 Exam Dumps - HPE Technical Certification Questions and Answers

The Intelligent Workload Optimizer is a feature of HPE SimpliVity that automatically balances the virtual machine workloads across the nodes in a cluster, based on the CPU, memory, and storage utilization1. This feature helps to improve the performance and efficiency of the cluster, and to avoid hotspots and bottlenecks. The Intelligent Workload Optimizer can be configured to run periodically or on demand, and it can also take into account the affinity and anti-affinity rules for the virtual machines2. The Resource Balancer (option A) is a feature of HPE SimpliVity that automatically balances the storage capacity across the nodes in a cluster, based on the free space and deduplication ratio3. This feature helps to optimize the storage utilization and availability of the cluster, and to avoid capacity issues and data loss. The Resource Balancer does not balance the virtual machine workloads or the I/O traffic. The Management Virtual Appliance (option B) is a component of HPE SimpliVity that provides the management interface and functionality for the cluster, such as backup, restore, clone, move, and federation operations4. The Management Virtual Appliance does not balance the virtual machine workloads or the I/O traffic. The Arbiter (option C) is a component of HPE SimpliVity that provides the quorum service for the cluster, ensuring data consistency and availability in the event of a node or site failure5. The Arbiter does not balance the virtual machine workloads or the I/O traffic. References:

According to the HPE SimpliVity Administration Guide1, one of the possible solutions to avoid the potential problem of CPU intensive applications impacting the performance of other virtual machines is to deploy the CPU intensive virtual machines on HPE SimpliVity, and configure for them CPU affinity parameter. This parameter allows you to specify which physical CPU cores are used by a virtual machine, and thus isolate the CPU intensive workloads from the rest of the virtual machines. This way, you can still leverage the HPE SimpliVity features, such as data efficiency, backup and restore, and federation management, for these virtual machines. The other options are not correct because:

• Presenting HPE SimpliVity datastores to external ESXi system that will house the CPU intensive virtual machines is not a recommended solution, as it will reduce the data efficiency and availability benefits of HPE SimpliVity, and introduce additional complexity and overhead in managing the external ESXi system1.
• Adding an external ESXi cluster to HPE SimpliVity Federation, and enabling Intelligent Workload Optimizer is not a recommended solution, as it will require additional hardware and software costs, and may not guarantee the optimal performance of the CPU intensive virtual machines, as the Intelligent Workload Optimizer is based on heuristics and not on strict rules2.
• Adding an external ESXi system to HPE SimpliVity cluster, and enabling DRS functionality for CPU intensive virtual machines is not a recommended solution, as it will violate the HPE SimpliVity cluster requirements, and may cause issues with the HPE SimpliVity federation and data protection features1. References: 1: HPE SimpliVity Administration Guide (A00019350ENW), pages 23, 25, 28, 32, 342: HPE SimpliVity Intelligent Workload Optimizer User Guide (A00019354ENW), pages 5, 7, 9.
