My question is, I have the possibility to setting up fault tolerance for my cluster vsphere 4 but not for single virtual machine but in the cluster level?
example I have configuration to HA and DRS in the cluster edit menu, but i don't have any that define fault tolerance.
FT is for guests, while HA is for ESX(i) Hosts. FT is business continuance, while with HA you get quick recovery of your guests, but there is a downtime of power down, power up.
there is a recommendation of 4FT vm per host due to the 1Gbps and only 1vCPU can be FT. Therefore you cant do a global FT.
I would recommend you to read this - http://communities.vmware.com/blogs/vmroyale/2009/05/18/vmware-fault-tolerance-requirements-and-limi...
