ndb cluster data node ulimit settings

In an NDB cluster setup on a VM environment, we have configured management node, data node and sql node in a single node, with 2 servers in cluster.

So both nodes have management node, data node and sql node components.
What should be the value for "max locked memory". It's 64KB by default on most Linux systems; of course, this is very small for a data node.

Whats the implication of setting it to "unlimited" in an NDB cluster environment? Whats the use of this parameter?

NDB Server version: 5.6.29-ndb-7.4.11-cluster-commercial-advanced-log
Storage provisioned through Oracle VM
OS: RHEL 6.5
