1.2 Hardware Components of Exalogic

The Exalogic machines consist of compute nodes, a storage appliance, and InfiniBand and Ethernet networking components. The number of these components in each machine varies based on the hardware configuration.

Note:

The hardware components listed in this chapter are for Exalogic machines shipped from the factory.

You can connect up to eight Exalogic machines, or a combination of Exalogic and Exadata on the same InfiniBand fabric, without the need for any external switches.

Note:

If more than eight racks of Exalogic or Exadata are required to be connected on the same InfiniBand fabric, Oracle offers a choice of several high-capacity datacenter switches, which allow the creation of Exalogic clouds consisting of hundreds of racks and tens of thousands of processors.

1.2.1 PDUs in Exalogic

Each Exalogic rack contains two redundant PDUs that are available in both high and low voltage options. The available PDU options can be found in the data sheets available at the following location:

Note:

When you upgrade to a full rack, you must upgrade to a three-phase 24 kVA PDU.

1.2.2 Spares Kit for Exalogic

The Exalogic machine includes a spares kit containing additional parts and accessories (cables, for example) that Oracle Services personnel will use to replace non-working and broken parts quickly. When Oracle Services personnel visit your site for repairing and replacing hardware, you should make the spares kit available to them. Note that any parts used by Oracle Service personnel from the spares kit will be replenished by Oracle.

1.2.3 Pre-cabling for Exalogic X4-2 and newer Machines

The eighth-, quarter-, and half-rack X4-2 and newer machines are pre-cabled with a complete set (equivalent in number to a full rack) of InfiniBand (92), Ethernet (42), and power cables. All the cables are connected to the appropriate switches and routed to the correct rack-unit location. The unconnected ends of the cables are tied off to lacer bars. At a later time, if the machine is upgraded to a larger rack, the filler panels and lacer bars are removed, the X4-2 and newer servers are installed with rack rails and cable-management arms, and the cables (power, InfiniBand, and Ethernet) are connected to the newly installed compute nodes.
