<title>Configure vCenter data stores for the Image Service back
end</title>
<?dbhtml stop-chunking?>
<para>To use vCenter data stores for the Image Service back end,
you must update the <filename>glance-api.conf</filename> file,
as follows:</para>
<itemizedlist>
<listitem>
<para>Add data store parameters to the <literal>VMware
Datastore Store Options</literal> section.</para>
</listitem>
<listitem>
<para>Specify vSphere as the back end.</para>
</listitem>
</itemizedlist>
<note>
<para>You must configure any configured Image Service data
stores for the Compute service.</para>
</note>
<para>You can specify vCenter data stores directly by using the
data store name or Storage Policy Based Management (SPBM),
which requires vCenter Server 5.5 or later. For details, see
<xref linkend="glance-backend-DS"/>. <note>
<para>If you intend to use multiple data stores for the
back end, use the SPBM feature.</para>

<para>In the <literal>DEFAULT</literal> section, set the
<parameter>default_store</parameter> parameter to
<userinput>vsphere</userinput>, as shown in this code
sample:</para>

<title>Configure vCenter data stores for the back end</title>
<para>You can specify a vCenter data store for the back end by
setting the <parameter>vmware_datastore_name</parameter>
parameter value to the vCenter name of the data store.
This configuration limits the back end to a single data
store.</para>
<para>Alternatively, you can specify a SPBM policy, which can
comprise multiple vCenter data stores. Both approaches are
described.</para>

<para>SPBM requires vCenter Server 5.5 or later.</para>
