Networking Requirements
The Undercloud requires a minimum of two networks: a provisioning network and an external network. The RHEL-OSP Director uses the provisioning network to provision and manage the Overcloud nodes. The external network is used to remotely connect to all the nodes.
Note | For detailed information about networking requirements, see the Red Hat Enterprise Linux OpenStack Platform 7 Director Installation and Usage |
Note | The Virtual Supervisor Module (VSM) management interface is not supported on the provisioning interface. |
Overcloud Node Requirements
Overcloud node requirements include identifying requirements for Compute nodes and Controller nodes. This section describes Overcloud requirements for Cisco Nexus 1000V for KVM.
Note | For detailed information about Overcloud requirements, see the Red Hat Enterprise Linux OpenStack Platform 7 Director Installation and Usage |
Compute Node Requirements
The compute nodes host the virtual machine instances launched in the virtual environment.
| Component | Minimum Requirement |
|---|---|
|
Processor |
64-bit x86 processor with support for the Intel 64 or AMD 64 CPU extensions. |
|
RAM |
6 GB |
|
Hard disk |
40 GB |
|
NIC |
2 x 1 Gbps NICs |
Note | Ensure that Intelligent Platform Management Interface (IPMI) functionality is enabled on each compute node. Refer to your server configuration manual for information on how to enable IPMI on the server. |
Note | For detailed information about compute node requirements, see the Red Hat Enterprise Linux OpenStack Platform 7 Director Installation and Usage |
