AOS supports the replacement of existing drives by larger drives when they become available. Nutanix facilitates these upgrades.
Empty drive slots in Cisco and Dell hardware models can be filled with additional physical disks when needed.

AOS 5.1 introduced general availability (GA) support for hot plugging virtual memory and vCPU on VMs that run on top of the AHV hypervisor from within the Self-Service Portal only. This means that the memory allocation and the number of CPUs on VMs can be increased while the VMs are powered on. However, the number of cores per CPU socket cannot be increased while the VMs are powered on.

AOS 5.11 with Foundation 4.4 and later introduces support for up to 120 Tebibytes (TiB) of storage per node. For these larger capacity nodes, each Controller VM requires a minimum of 36GB of host memory.
