- `MaxGCEPDVolumeCount`: Ensure that the number of attached GCE PersistentDisk volumes does not exceed a maximum value (by default, 16, which is the maximum GCE allows -- see [GCE's documentation](https://cloud.google.com/compute/docs/disks/persistent-disks#limits_for_predefined_machine_types)). The maximum value can be controlled by setting the `KUBE_MAX_PD_VOLS` environment variable.
- `CheckNodeMemoryPressure`: Check if a pod can be scheduled on a node reporting memory pressure condition. Currently, no ``BestEffort`` should be placed on a node under memory pressure as it gets automatically evicted by kubelet.
The details of the above predicates can be found in [plugin/pkg/scheduler/algorithm/predicates/predicates.go](http://releases.k8s.io/v1.4.0-alpha.0/plugin/pkg/scheduler/algorithm/predicates/predicates.go). All predicates mentioned above can be used in combination to perform a sophisticated filtering policy. Kubernetes uses some, but not all, of these predicates by default. You can see which ones are used by default in [plugin/pkg/scheduler/algorithmprovider/defaults/defaults.go](http://releases.k8s.io/v1.4.0-alpha.0/plugin/pkg/scheduler/algorithmprovider/defaults/defaults.go).

- `ImageLocalityPriority`: Nodes are prioritized based on locality of images requested by a pod. Nodes with larger size of already-installed packages required by the pod will be preferred over nodes with no already-installed packages required by the pod or a small total size of already-installed packages required by the pod.
- `NodeAffinityPriority`: (Kubernetes v1.2) Implements `preferredDuringSchedulingIgnoredDuringExecution` node affinity; see [here](../user-guide/node-selection/) for more details.
