2.1 Network Requirements

Learn about the network requirements for OPCM.

10 GbE Network Requirements

The following table shows the minimum network requirements to install an Oracle Public Cloud Machine machine:

Table 2-1 OPCM 10 GbE Network Requirements.

Network Requirement Description
Data center network services

  • DNS entries for all physical components on eth-admin and control VM’s EoIB-management.

  • NTP server.

  • Gateway.
Minimum 10 GbE uplinks to your data center

At least 2 uplinks for EoIB (Ethernet over InfiniBand) infrastructure service and client access networks.
External access service network VLANs

  • EoIB-OMS (minimum /24, tagged VLAN). For communication between EMCC (Enterprise Manager Cloud Control) OMS and EM (Enterprise Manager) agents, Control virtual machines (VMs), and Guest VMs.

  • EoIB-management (minimum /26, tagged VLAN). For accessing IaaS API and VNC consoles of instances and for PaaS Engines.

  • EoIB-public (minimum /26, tagged VLAN). For communication with Integration Cloud Service (ICS) instances and for external routing of VMs and Virtual IPs (VIP).

  • EoIB-dbaccess (tagged VLAN). For accessing the external database for ICS. This network is required only if you subscribe to ICS. See Other Requirements for more information.
External access client VLANs

  • Minimum: 1 VLAN for tenant access ( /24, tagged VLAN).

  • Recommendation: 1 VLAN per tenant for isolation.
Maximum 10 GbE network drops

  • For OPCM model 1080: 32

  • For model 576: 16

  • For model 288: 16
Minimum 10 GbE network drops

  • For OPCM model 1080: 4

  • For model 576: 2

  • For model 288: 2
Ethernet devices

10 Gb Ethernet switch, router, or NIC device that supports: SFP+ 10G-Base-SR Module, XFP 10G-Base-SR Module, or QSFP Optical Module.

Connect the network drops to multiple 10GbE switches to ensure no single point of failure exists in the physical routing.

The number of network connections from the gateway ports to the data center switches depend upon customer application throughput and network isolation requirements.
IP addresses

OPCM requires a large number of host names and IP addresses for the initial configuration. The number of IP addresses required for a particular network, such as the management network, depends on the type of system. In addition, all IP addresses must be statically assigned and not dynamically assigned (DHCP).

Oracle technical representatives work with you to gather all the information needed for the network configuration, including host names and IP addresses used for the installation. Configure the new IP addresses in your existing networks only after you have completed to work on the configuration information with an Oracle representative.

1 GbE Network Requirements

Table 2-2 OPCM 1 GbE Network Requirements.

Network Requirement Description
1 GbE network drops

1 network drop. If you require a redundant connection, Oracle can work with you for an additional network drop.

All OPCM physical components connect to the internal Cisco switch that provides connectivity to your 1GbE management network for managing physical components and dom0.
1GbE management subnet

  • Recommended minimum /24.

  • This network allows connectivity to the Ethernet management interface on OPCM physical components, such as compute nodes, storage nodes, their ILOMs, network switches, and power distribution units as well as the privileged control VMs.
