Power. HA on AIX with DLPAR cost savings example U. S. example actual results may vary by country • Power. HA and AIX are priced per processor core (license only the cores being used in the cluster) • Taking advantage of the DLPAR technology in the example topology: – Assume 770 cluster, 7 AIX and 7 Power. HA – Power. HA price: 5, 000/core = $35, 000…. . 75, 000 – 35, 000 = savings: $40, 000 – AIX price: 2145/core + 530/core = 2675/core = $40, 125 – $21, 400…. . savings: $18, 725 – Total savings…. $58, 725 © Copyright IBM Corporation 2014
