Abstract

A computer implemented method for sharing physical memory among logical partitions. A computer reserves physical memory of a Central Electronic Complex (CEC) for communication within the CEC as a shared memory pool. The computer creates a first logical partition using resources of the CEC that are not reserved as the shared memory pool. The computer creates a second logical partition using resources of the CEC that are not reserved as the shared memory pool. The computer creates a virtual local area network (VLAN) having at least two addresses within the CEC. The computer allocates a portion of the shared memory to the VLAN as the shared memory pool.
