LDoms and the PCIe Slots Overview

LDom configurations supported on SuperCluster M6-32 have the following characteristics:

• One to four LDoms on one or two DCUs

• Each LDom can be one of the following types:

  • Database Domain (dedicated domain)

  • Application Domain running Oracle Solaris 10 (dedicated domain)

  • Application Domain running Oracle Solaris 11 (dedicated domain)

  • Root Domain

Each DCU in the compute server has sixteen PCIe slots. The following cards are installed in certain PCIe slots and are used to connect to these networks:

• One quad-port 1GbE NIC – Used to connect to the management network

• Four IB HCAs – Used to connect to the private IB network

Each DCU also has four EMS cards, each with two 10GbE ports, which are used to connect to the 10GbE client access network.

The PCIe slots and EMSs used for each configuration varies, depending on the type and number of LDoms that are used for that configuration.
