NIC bonding

[fjdhdhcyfhf]

Im just rebuilding my computers and backing up my data etc. Iv used bonding on debian in the past and Im looking at bonding in ubuntu server, but then I came across teaming from redhat. Anyone used teaming?

[Electronics Wizardy]

Teaming = bonding

 

There are different ways of setting it up(fail over and higher speed being the main ones)

 

 

[KuJoe]

This is new to me, I use bonding on all of my CentOS servers but now I'm building up some CentOS VMs to test out teaming. I'm not too interested in the features but the CPU usage compared to bonding is impressive considering lower CPU utilization is more beneficial to me.

 

A nice link with nice tables: http://rhelblog.redhat.com/2014/06/23/team-driver/

Do you mean its the same bonding driver found in Debian but Redhat just calls it teaming?

No, teaming and bonding are different. I thought they were the same thing also until I searched for it. Looks like RedHat even has a script for me to migrate from bonding to teaming if I find it worth it.

That is not correct. Bonding != Teaming. I thought so also but it's a completely different driver and feature set.

If the reduced CPU translated to lower power it would be beneficial to me. My server just serves up files, doesn't do anything special like multimedia streaming

so no need for bonding or teaming then.

Technically different implementations, in the software sense, of the same thing with Teaming being the newer and better implementation.

let me know how that goes. iv got about two days to do some reading before my new CAT cables arrive. Ill prob be running three or four NICs direct between my computers, depending on what speed I can get out of my hard drives

[KuJoe]

I only use bonding on my servers in case a switch or a NIC dies.

 

Also I just noticed I was looking at the chart wrong, the CPU utilization between bonding and teaming isn't that big.

yes there is need. theres more to computers than 4k cat videos

If you can let us know what you need the network capacity for we can give you better advice. I don't utilize more than 1Gbps of bandwidth at a time so I don't use LACP, just the failover function of bonding.

but you can't use it if you don't have more than one network connection

I don't think I'll be testing teaming now after reading the chart correctly. There isn't much performance improvement and the CPU utilization is within a few percent so with so many cores I won't see a big difference on my end. No point in me making a project and scheduling a bunch of changes over a few % and Mbps.

i want it as fast as it can go. backups, virtual machine storage. Iv also got a very large copy of wikipedia xml files for experimenting on. Iv pretty much outsourced my mechanical drive requirements to reduce noise and also keep my data in a safe place from thieves.

what? i lost you man. Im not connecting my server to the internet. i filled all the PCI slots with gigabit NICs for local LAN

Does your switch support LACP and have a backplane capable of more than 1Gbps? How many devices will be accessing the server at one time? Are you using SSD caching or anything like that? What kind of RAID setup will you have and are all the drives SATA III 7200 RPM or will you have some slower drives?

Thanks I dont need help with that stuff and I think you will understand i really dont want to publish my setup publicly. I was just wondering about teaming. I keep landing on bonding driver setup when I search for it

As long as you're aware that bonding/teaming will not improve your network performance for single threaded connections. I'd hate to see you go through all of this work and not get any performance improvements out of it.

Are you using SSD caching

How much difference does SSD cacheing make on a RAID array? I have an old spare 60Gb SSD lying around. Do you think it would be appropriate to use a five year old SSD as a cache? its from my old laptop and last time i did a SMART check it reported something like 13months of total use. Iv been using it in a USB adapter infrequently for over a year so I dont think its super old
