<title>Oracle ZFSSA iSCSI Driver</title>
<para>Oracle ZFS Storage Appliances (ZFSSAs) provide advanced software to protect data, speed tuning and
troubleshooting, and deliver high performance and high availability.
Through the Oracle ZFSSA iSCSI Driver, OpenStack Block Storage can use an Oracle ZFSSA as a block storage resource.
The driver enables you to create iSCSI volumes that an OpenStack Block Storage server can allocate to any virtual machine running on a compute host.
The Oracle ZFSSA iSCSI Driver, version <literal>1.0.0</literal>, supports ZFSSA software release <literal>2013.1.2.0</literal> and later.
