Hi Carlo,

It's possible by setting up two clusters;
one serves SSD and another does SATA.
For this, you can run two sheep daemons per server.

First, see slides below about installation (pp.14-15):

Then, if you use libvirt, configure your virtual disk(s) like below.
Please make sure to use appropriate PORT_NUMBER:

 <disk type="network">
  <driver name="qemu" type="raw"/>
   <source protocol="sheepdog" name="${VOLUME_NAME}">
    <host name="localhost" port="${PORT_NUMBER}"/>
  <target dev="vda" bus="virtio"/>

Best regards,

Takashi Menjo <menjo.takashi at lab.ntt.co.jp>
