B.2. Services Configuration Settings

The following table outlines the options available in the Services Configuration step of creating a new deployment.

Table B.2. Services Configuration Settings

Service Option Description  
Neutron Tenant Network Type The type of network used for tenant networks. You can choose from the following options:
  • VXLAN Segmentation: Virtual extensible LAN. A network layout that extends the functionality of a VLAN by providing a larger network segment ID range and other features.
  • GRE Segmentation: Generic routing encapsulation segmentation. A network layout in which tunnels are used to segregate and carry network traffic over individual tenant networks.
  • VLAN Segmentation: A network layout in which multiple isolated networks are defined. If you choose this option, you must also specify the tenant VLAN range.
  • Flat: A simple network layout in which all instances are members of the same network.
 
  Core Plugin Type
The core network plugin. You can choose from the following options:

ML2 Core Plugin

The modular layer 2 plugin. If you select this plugin, you can select the following ML2 mechanism drivers:
  • Open vSwitch: A software-defined networking virtual switch designed to supersede the heritage Linux software bridge. Open vSwitch provides switching services to virtualized networks with support for industry-standard NetFlow, OpenFlow, and sFlow.
  • L2 Population: Enables horizontal scaling of broadcast, multicast, and unicast traffic on large overlay networks. L2 population implements a partial mesh for ARP resolution and MAC learning traffic whereby this traffic is sent only to the necessary agent by encapsulating it as a targeted unicast.
    Note that if this this item is enabled, the installer sets the Layer 3 HA Configuration (l3_ha) to false. This is due to incompatibility to having l3_ha and l2pop enabled.
  • Cisco Nexus: Enables configuration of Cisco Nexus switches. If you select this option, you must enter the Switch Hostname, Switch IP Address, Switch Login, Switch Password, SSH Port, and Port Mappings. You can add additional switches by clicking Add Another Switch.

N1KV Core Plugin

The Cisco 1000v plugin. If you select this plugin, you must also specify the details of a virtual supervisor module:
  • VSM IP: The IP address of the virtual supervisor module.
  • VSM Password: A password with which to authenticate with the virtual supervisor module.
 
Nova Tenant Network Type
  • Flat with DHCP: A simple network layout in which all instances are members of the same network, and the DHCP service is also provided.
  • VLAN: A network layout in which multiple isolated networks are defined. If you choose this option, you must also specify the tenant VLAN range.
 
  Floating IP range for external network A range of IP addresses to be used for external networks. Ranges must be entered using CIDR notation. For example, XX.XX.XX.0/24.  
  Fixed IP range for tenant networks A range of IP addresses to be used for tenant networks. Ranges must be entered using CIDR notation. For example, XX.XX.XX.0/24.  
Glance Choose Driver Backend The driver to use for back-end storage of images. You can choose from the following options:
  • Local File: The local file system. This option is only available in deployments without high availability.
  • Ceph: Ceph storage.
  • NFS: Network file system storage. If you select this option, you must also specify the NFS address in the network path text field.
 
Cinder Choose Driver Backend The volume driver to use for back-end storage. You can choose from the following options:
  • LVM: Logical volume manager storage. This option is only available for deployments without high availability.
  • NFS: Network file system storage. If you select this option, you must also specify the NFS address in the NFS URI text field.
  • Ceph: Ceph storage.
  • EqualLogic: For EqualLogic storage attached network systems. If you select this option, you must also specify the details of the storage attached network, including the SAN IP Addr, SAN Login, SAN Password, Pool, and Group.
  • NetApp for NetApp storage systems. If you select this option, you must also specify the details of at least one storage system. The options for these fields change depending on what you choose for the Storage Family, and Storage Protocol. You can add additional storage systems by clicking the Add Another NetApp Storage System.
