| − | xCAT can be used to manage virtual servers spanning across multiple z/VM partitions. The xCAT management node (MN) runs on any Linux virtual server. It manages each z/VM partition using a System z hardware control point (zHCP) running on a privileged Linux virtual server. The zHCP interfaces with z/VM systems management API (SMAPI), directory manager (DirMaint), and control program layer (CP) to manage the z/VM partition. It utilizes a C socket interface to communicate with the SMAPI layer and VMCP Linux module to communicate with the CP layer.
