You can remove Flash Accel software from ESXi hosts and virtual machines when you no longer need it. You can also remove the Flash Accel Management Console from the ESXi host.
Uninstalling Flash Accel software from hosts or VMs on which caching is still being performed is not recommended. You should disable caching on all devices before uninstalling the Flash Accel software.
You can uninstall the Flash Accel Management Console virtual machine from the ESX server when you no longer plan to use Flash Accel to provide caching to the ESXi servers in the vCenter domain.
