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:
