And now I've read the second part of your post where you want higher bandwidth. Linux bonding mode 0 (balance-rr) is able to give you aggregate bandwidth to the total sum of your interfaces (i.e.: bonding over 4x 1GbE interfaces will give you 4gbit/s). There are some caveats with certain switches, however. The "smarter" the switch, often the more problems you'll have (managed switches sometimes don't like seeing MAC addresses moving quickly between physical ports). If that's the case, your switch should support some sort of IEEE 802.1ax or IEEE 802.3ad features, in which cache if you hash on receiving MAC (instead of receiving IP), you'll get the same aggregate bandwidth result. You can use bonding mode 4 on the Linux nodes to then allow the switch to set these modes. If you're using unmanaged switches however, then bonding mode 0 (balance-rr) is what you're after. -Dan ---------------- Dan Mons R&D SysAdmin Unbreaker of broken things Cutting Edge http://cuttingedge.com.au On 13 January 2014 08:52, Dan Mons <dmons@xxxxxxxxxxxxxxxxxx> wrote: > I've configured all of my Gluster nodes to use standard Linux Ethernet bonding. > > We've got Myricom PCI-E 10GBE cards with two NICs per card, bonded > with the balance-xor (mode 2) option.
