|
|
<para>The SolidFire Cluster is a high performance all SSD iSCSI
|
|
storage device that provides massive scale out capability and
|
|
extreme fault tolerance. A key feature of the SolidFire
|
|
cluster is the ability to set and modify during operation
|
|
specific QoS levels on a volume for volume basis. The
|
|
SolidFire cluster offers this along with de-duplication,
|
|
compression, and an architecture that takes full advantage of
|
|
SSDs.</para>
|
|
<para>To configure the use of a SolidFire cluster with Block
|
|
Storage, modify your <filename>cinder.conf</filename> file as
|
|
follows:</para>
|
|
<programlisting language="ini">volume_driver = cinder.volume.drivers.solidfire.SolidFireDriver
|
|
san_ip = 172.17.1.182 # the address of your MVIP
|
|
san_login = sfadmin # your cluster admin login
|
|
san_password = sfpassword # your cluster admin password
|
|
sf_account_prefix = '' # prefix for tenant account creation on solidfire cluster (see warning below)</programlisting>
|
|
<warning>
|
|
<para>The SolidFire driver creates a unique account prefixed
|
|
with
|
|
<literal>$cinder-volume-service-hostname-$tenant-id</literal>
|
|
on the SolidFire cluster for each tenant that accesses the
|
|
cluster through the Volume API. Unfortunately, this
|
|
account formation results in issues for High Availability
|
|
(HA) installations and installations where the <systemitem
|
|
class="service">cinder-volume</systemitem> service can
|
|
move to a new node. HA installations can return an
|
|
<errortext>Account Not Found</errortext> error because
|
|
the call to the SolidFire cluster is not always going to
|
|
be sent from the same node. In installations where the
|
|
<systemitem class="service">cinder-volume</systemitem>
|
|
service moves to a new node, the same issue can occur when
|
|
you perform operations on existing volumes, such as clone,
|
|
extend, delete, and so on.</para>
|
|
</warning>
|
|
<note>
|
|
<para>Set the <option>sf_account_prefix</option> option to an empty string ('') in the
|
|
<filename>cinder.conf</filename> file. This setting results in unique accounts being
|
|
created on the SolidFire cluster, but the accounts are prefixed with the
|
|
<systemitem>tenant-id</systemitem> or any unique identifier that you choose and are
|
|
independent of the host where the <systemitem class="service">cinder-volume</systemitem>
|
|
service resides.</para>
