Hi All, The $Subject came about as part of a comparision exercise between the best possible solutions for a HA cluster that span across at the very least two geographical sites. For example, in a two node cluster (Active-Passive): Node 1 (N1) located in DataCenter A (DCA) and node 2 (N2) located in DataCenter B ( DCB). The distance between DCA & DCB is < 200 miles. The nodes will connect to an DMX800 via 2 HBAs using Brocade-FCSwitches in DCA N1 runs all the services while N2 is the back-up. Is the $Subject supported by RH ?
