Abstract

A METHOD, COMPUTER PROGRAM PRODUCT, AND DISTRIBUTED DATA PROCESSING SYSTEM FOR SUPPORTING RNIC (RDMA ENABLED NIC) SWITCHOVER AND SWITCHBACK ARE PROVIDED. USING THE MECHANISM PROVIDED IN THE PRESENT INVENTION WHEN A PLANNED OR UNPLANNED OUTAGE OCCURS ON A PRIMARY RNIC, ALL OUTSTANDING CONNECTIONS ARE SWITCHED OVER TO AN ALTERNATE RNIC , AND THE ALTERNATE RNIC CONTINUES COMMUNICATION PROCESSING. ADDITIONALLY,USING THE MECHANISM PROVIDED IN THE PRESENT INVENTION, CONNECTIONS CAN ALSO BE SWITCHED BACK.(FIGURE 1)
