Thanks for your thoughts. The problem is, most of the data is transmitted from a couple apps to a couple systems. The chance of a hash collision (i.e., most of the data going out the same interface anyway) is quite high. On Solaris, I just created two physical interfaces each with their own IP, and bound the apps to the appropriate interfaces. This worked great. Imagine my surprise when I discovered this doesn’t work on Linux and my crash course on weak host models.Interesting that no one commented on my thought to just do the bonding at the guest level (and use balance-alb) instead of at the hypervisor level. Some ESXi experts I have talked to say this is actually the preferred method with ESXi and not to do it at the hypervisor level, as the VM knows better than VMware.Or is the bonding mode issue with balance-alb/tlb more with the Linux TCP stack itself and not with oVirt and VDSM?On Dec 30, 2014, at 4:34 AM, Nikolai Sednev <nsednev@redhat.com> wrote:_______________________________________________Mode 2 will do the job the best way for you in case of static LAG supported only at the switch's side, I'd advise using of xmit_hash_policy layer3+4, so you'll get better distribution for your DC.
Thanks in advance.Best regards,

This switch is more of an office switch and only supports part of the
802.3ad standard:
PowerConnect* *2824Scalable from small workgroups to dense access solutions, the 2824
offers 24-port flexibility plus two combo small?form?factor
pluggable (SFP) ports for connecting the switch to other networking
equipment located beyond the 100 m distance limitations of copper
cabling.Industry-standard link aggregation adhering to IEEE 802.3ad
standards (static support only, LACP not supported)
So the only way to have some kind of bonding without buying more
expensive switches, is using balance-rr (mode=0), balance-xor (mode=2)
or broadcast (modes=3).

Sorry, no mode 0. So only mode 2 or 3 for your environment....Kind regards,JorickMet vriendelijke groet, With kind regards,Jorick AstregoNetbulae Virtualization Experts----------------Tel: 053 20 30 270 info@netbulae.eu Staalsteden 4-3A KvK 08198180
