-  <para>You can access gluster volumes in  multiple ways. You can use Gluster Native Client method for high concurrency, performance and transparent failover in GNU/Linux clients. You can also use NFS v3 to access gluster volumes. Extensive testing has be done on GNU/Linux clients and NFS implementation in other operating system, such as  FreeBSD, and Mac OS X, as well as Windows 7 (Professional and Up) and Windows Server 2003. Other NFS client implementations may work with gluster NFS server.</para>
-  <para>You can use CIFS to  access volumes when using Microsoft Windows as well as SAMBA clients. For this access method, Samba packages need to be present on the client side. </para>
