<p>Hello everyone,<br />we are using pacemaker on a 2-Nodes cluster with an qnap-NAS as iscsi and its working well.</p><p>For more power we bought 10GB-Nics for the Server and a 2x10GB Card for the NAS. </p><p> </p><p>How could we use this hardware without using an 10GB switch?</p><p>First try was to use the Port Trunking "Active Backup" on the NAS. This is working if i pullout the cable, then the other NIC is going active and the cluster can use the second port and second node.</p><p>I think the other Port Tunking-options are also not for our scenario (Balance-rr,Balance XOR,Broadcast,IEEE 802.3ad,Balance-tlb,Balance-alb) Maybe we could Broadcast a try?<br /></p><p> </p><p>The other Idea is to use different IP-Adresses for the iscsi-Ressources on the nodes. But this seems also very complex?</p><p> </p><p>Do you think its possible or does we need a 10GB Switch, this would cost a little bit and is one more Hardware which could be damage.</p><p> </p><p>Thanks in advance</p><p>Alex</p><p> </p><p> </p><p>Alexunil Ltd.<br />Kettelerstr. 16<br />85375 Neufahrn b.
