Hello List,
i am very new to ovirt. I am setting up a 2 Node Cluster with GlusterFS Sync Replication.
I was about to buy a 2-Port Intel Gbit nic for each host which is about 150Eur each.
However, for a little extra of 180Eur you get a 10GBit Infiniband - MCX311A-XCAT.
I would like to have quick opinions on this.
Should i pay a little more and then get 10MBit instead of 2GBit bonded?
Infiniband is good for GlusterFS / storage connection but never never never never ever use it as a vm network - believe me it's a nightmare. So you would direct connect your 2 nodes as otherwise you would have to buy an Infiniband switch as well (btw I'm not sure if direct connect is possible, but I guess it is). Keep in mind that Infiniband cables aren't cheap, too. Why don't you go for 10Gbit/s Ethernet?
Thanks, michel
