Hello guys,<br>
<br>
'Coz DRBD nodes sync data all through the GigE network(normal topology).<br>
Does it make sense that use Infiniband hardware replace GigE as the<br>
inter-connection link for DRBD nodes to have outstanding performance boost?<br>

We use IPoIB, it's a performance hit, over verbs, but much better then GigE.<div><br>

We have deployed a 4 nodes Oracle RAC Cluster 1 years ago with HP's<br>
infiniband products and gained big performance improvement. This encourage<br>
us to think of this day-and-day cheaper hardware solution for a faster DRBD<br>
cluster.<br>

With all of the Infiniband parts on ebay, or even the cost new it is worth it.<br>
