Load Balanced Volume GroupsLoad Balanced Volume Groups
AHV hosts support load balancing of vDisks in a volume group for user VMs. Load balancing of vDisks in a volume group enables IO-intensive VMs to utilize resources such as the CPU and memory of multiple Controller VMs (CVMs). vDisks belonging to a volume group are distributed across the CVMs in a cluster thereby improving […]
Scale out Prism CentralScale out Prism Central
In AOS 5.6 you can expand Prism Central from a single VM to three VMs, increasing the capacity and resiliency of Prism Central. If Prism Central is just a single VM currently, you can expand it to three VMs. This increases both the capacity and resiliency of Prism Central (at the cost of maintaining two […]
