Table 1. Host hardware
System Operating System Number of CPUs Memory in GB Network Architecture
Oracle RAC node1 SLES 10 SP2 Two or three, dedicated 16
  • One 1 Gb OSA
  • One HiperSockets™ or 10 Gb OSA
 z10™ LPAR
Oracle RAC node2 SLES 10 SP2 Two or three, dedicated 16
  • One 1 Gb OSA
  • One HiperSockets or 10 Gb OSA
 z10 LPAR
The IBM® System z10® had these features.
  • Two LPARs, each with
    • Two or three processors, dedicated
    • 16 GB of memory
    • HiperSockets connection
    • One OSA Express3 1 Gb Ethernet
    • One OSA Express3 10 Gb Ethernet
  • Eight FICON® Express® 4 (4 GB), shared
  • ECKD™ disk devices (DASD) on IBM System Storage® DS8000
    • 16 ranks are spread across the logical configuration of the control unit to avoid congestion.
    • The storage server is connected to the IBM System z® with eight FICON paths.
