Subject RE: CLoudStack and OpenFiler2.99
Date Thu, 20 Sep 2012 15:54:35 GMT
On the management server you could do tagged interfaces (VLAN) on the same NIC, but on your
hosts I would recommend using 1 NIC for storage and 1 NIC for management and guest traffic.

For your VLAN question.  You can put both VLANs on the same interface if
you want, but I recommend that you keep management and storage traffic on
separate NICs for performance reasons. ==> on the* Management server* NICs
same ? I separate also to the *Host *NICs  ?
