If many snapshots are requested for VMs on a single host, this can lead to problems with too many snapshot jobs overwhelming the resources of the host."

By using this setting, the administrator can better ensure that snapshot jobs do not time out and hypervisor hosts do not experience performance issues due to hosts being overloaded with too many snapshot requests."

If a given host has more snapshot requests, the additional requests are placed in a waiting queue. No new snapshot jobs will start until the number of currently executing snapshot jobs falls below the configured limit."
