Methods of managing loads on a plurality of secondary data servers whose workflows are controlled by a primary control server

A method of managing workflow loads on a plurality of secondary data servers whose workflows are controlled by a primary control server, the method comprising:

• initially directing workflow to only a first data server of the plurality of secondary data servers;
• monitoring an arrival rate of workflow to the first data server;
• after a first predetermined minimum load level of work to the first data server has been reached, continue directing work to the first data server until a first predetermined maximum load level of work to the first data server is reached;
• and
• directing workflow from the first data server to a second data server of the plurality of secondary data servers after the first predetermined maximum load level of work to the first data server is reached and the arrival rate of workflow to the first data server exceeds a first predetermined arrival rate value.

A method of managing workflow loads on a plurality of secondary data servers whose workflows are controlled by a primary control server, the method comprising:

• initially directing workflow to only a first data server of a plurality of secondary data servers;
• monitoring a queue depth value associated with workflow of an application-specific service provided by the first data server;
• comparing the queue depth value of the first data server with a first predetermined minimum queue depth threshold value which is stored in memory;
• and
• directing workflow from the first data server to an idle second data server of the plurality of secondary data servers when the queue depth value associated with workflow of the application-specific service provided by the first data server exceeds the first predetermined minimum queue depth threshold value.
