Hi Allessandro,

To achieve this you would probably have to:

- Set  global setting “host.capacityType.to.order.clusters” to RAM (default is 
CPU)
- Set *cluster setting* “cluster.memory.allocated.capacity.disablethreshold” to 
0.90.
- You may also want to review cluster settings 
cluster.cpu.allocated.capacity.disablethreshold, 
cluster.cpu.allocated.capacity.notificationthreshold and 
cluster.memory.allocated.capacity.notificationthreshold.

Hope this helps.

    Hi guys,
    just a question about host allocation.
    My infrastructure is based on CS 4.5 and XS 6.5, host allocation is
    "random" but I see that CS allocate hosts to completely fill the RAM.
    I've some hosts with 148 GB RAM usable and 148 GB used, completely filled.
    This obviously means that XS will swap to HD and instances performance is
    reduced...
    How can I tell to CS to allocate the hosts up to 90% its RAM?
    
    Thank you!
