<para>For both conserving network resources and ensuring that
|
|
network administrators understand the needs for networks and
|
|
public IP addresses for providing access to the APIs and storage
|
|
network as necessary, this section offers recommendations and
|
|
required minimum sizes. Throughput of at least 1000 Mbps is
|
|
suggested.</para>

<para>This guide describes the following networks:<itemizedlist>

<para>A mandatory public network. Connects to the proxy

server.</para>

<para>A mandatory storage network. Not accessible from outside

the cluster. All nodes connect to this network.</para>

<para>An optional replication network. Not accessible from

storage nodes. Must be configured in the Ring.</para>

<para>By default, all of the OpenStack Object Storage services, as

|
well as the rsync daemon on the storage nodes, are configured to
|
|
listen on their <literal>STORAGE_LOCAL_NET</literal> IP
|
|
addresses.</para>
|
|
<para>If you configure a replication network in the Ring, the
|
|
Account, Container and Object servers listen on both the
|
|
<literal>STORAGE_LOCAL_NET</literal> and
|
|
<literal>STORAGE_REPLICATION_NET</literal> IP addresses. The

rsync daemon only listens on the

<literal>STORAGE_REPLICATION_NET</literal> IP address.</para>
