<para>For both conserving network resources and ensuring that
|
|
network administrators understand the needs for networks and
|
|
public IP addresses for accessing the APIs and VMs as
|
|
necessary, this section offers recommendations and required
|
|
minimum sizes. Throughput of at least 1000 Mbps is suggested.
|
|
This walkthrough shows network configurations for a single
|
|
server.</para>
|
|
<para>For OpenStack Compute, networking is configured on
|
|
multi-node installations between the physical machines on
|
|
a single subnet. For networking between virtual machine
|
|
instances, three network options are available: flat,
|
|
DHCP, and VLAN. Two NICs (Network Interface Cards) are
|
|
recommended on the server running nova-network.</para>
|
|
<para>Management Network (RFC1918 IP Range, not publicly
|
|
routable): This network is utilized for all inter-server
|
|
communications within the cloud infrastructure. Recommended
|
|
size: 255 IPs (CIDR /24)</para>
|
|
<para>Public Network (Publicly routable IP range): This network is
|
|
utilized for providing Public IP accessibility to the API
|
|
endpoints within the cloud infrastructure. Minimum size: 8 IPs
|
|
(CIDR /29)</para>
|
|
<para>VM Network (RFC1918 IP Range, not publicly routable): This
|
|
network is utilized for providing primary IP addresses to the
|
|
cloud instances. Recommended size: 1024 IPs (CIDR /22)</para>
|
|
<para>Floating IP network (Publicly routable IP Range): This
|
|
network is utilized for providing Public IP accessibility to
|
|
selected cloud instances. Minimum size: 16 IPs (CIDR
|
|
/28)</para></section>
