Re: [ovirt-users] 1. Re: ??: bond mode balance-alb (Jorick Astrego)

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?

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). >> I just tested mode 4, and the LACP with Fedora 20 appears to not be >> compatible with the LAG mode on my Dell 2824. >> >> Would there be any issues with bringing two NICS into the VM and doing >> balance-alb at the guest level? >> Kind regards, Jorick Astrego Met vriendelijke groet, With kind regards, Jorick Astrego Netbulae Virtualization Experts ---------------- Tel: 053 20 30 270 info(a)netbulae.eu Staalsteden 4-3A KvK 08198180 Fax: 053 20 30 271 www.netbulae.eu 7547 TA Enschede BTW NL821234584B01 ---------------- -------------- next part -------------- An HTML attachment was scrubbed...
