Abstract: Failover of blade servers in a data center, including powering off by a system management server a failing blade server, the failing blade server characterized by a machine type, the failing blade server mapped to remote computer boot storage administered through a Storage Management Initiative-Specification (‘SMI-S’) provider; identifying, by the system management server by use of the SMI-S provider from a pool of standby blade servers, a replacement blade server; remapping by the system management server through the SMI-S provider the remote computer boot storage of the failing blade server to the replacement blade server; and powering on the replacement blade server by the system management server.

Abstract: Applying firmware updates to servers in a data center, the servers including one or more active servers and a standby server, each server mapped to separate remote computer boot storage, including applying the firmware updates to the standby server; selecting an active server for firmware updating; powering off the selected active server by the system management server; remapping the standby server to the remote computer boot storage for the selected active server; rebooting the standby server from the remote computer boot storage for the selected active server, designating the standby server as an active server; remapping the selected active server to the remote computer boot storage formerly mapped to the standby server; and rebooting the selected active server from the remote boot storage formerly mapped to the standby server, designating the selected active server as a standby server.

Abstract: A control system for controlling the location of the nucleate-boiling region in a fluid heated steam generator comprises means for measuring the temperature gradient (change in temperature per unit length) of the heating fluid along the steam generator; means for determining a control variable in accordance with a predetermined function of temperature gradients and for generating a control signal in response thereto; and means for adjusting the feedwater flow rate in accordance with the control signal.
