<div class="moz-cite-prefix">Indeed. There is room for improvement :
should the 2 disks be RAID1 or parts of the same VG, as said ?<br>
<br>
As it is recommended hardware, it would be interesting to know
which kind of setup with 2 SATA disks is optimal ?<br>
<br>
Of course, it does depend a lot of the usage : if you need to boot
from volume, I would say having 2 physical PVs is better, but if
you need to store critical data, then the RAID one is fine.<br>

Hi everyone !
<div><br>
</div>
<div>I found these ones in the documentation :
"Volume storage: two disks with 2 TB (SATA)
for volumes attached to the compute nodes".
And I don't understand this sentence. Someone
can explain to me this sentence, please ?</div>

<div>Thanks !</div>
