Uplinks

Learn about uplink requirements for Exadata Cloud at Customer.

An Oracle Cloud at Customer environment with Exadata Cloud at Customer has the following uplink requirements.

• To support the Oracle cloud management network, there is a requirement to connect the Ethernet switch in the Exadata Cloud at Customer rack to the Cloud Control Plane, which is in turn connected to the Oracle Advanced Support Gateway.

• The physical network connections for the client network and the backup network are all concentrated through a pair of top-of-rack switches. Depending on your overall Exadata Cloud at Customer configuration, the top-of-rack switches may reside in one or more Exadata Cloud at Customer racks, or in the Cloud Control Plane rack.

  As a minimum, you require uplinks to connect the Cloud Control Plane top-of-rack switches to your corporate network. However, depending on your configuration, you may also choose to configure additional uplinks from the Exadata Cloud at Customer top-of-rack switches to your corporate network. Additional uplinks provide greater redundancy and can protect against some types of network failures. Additional uplinks also provide greater network bandwidth between your corporate network and your Exadata Cloud at Customer environment.

  For each set of uplinks, Oracle recommends at least two physical connections; that is, at least one link from each top-of-rack switch to your corporate network. However, for greater resilience and increased bandwidth, Oracle recommends 4 uplinks to connect the top-of-rack switches to a pair of customer-supplied network switches. In this configuration, the connections are to be arranged so that each top-of-rack switch is connected to both customer switches, and each customer switch is connected to both top-of-rack switches. Oracle recommends this arrangement to ensure that no single point of failure exists in the physical network, and also to provide sufficient network bandwidth for network-intensive applications.
