Dear members,
I would like to use two switches for make high-availability network connection for my nfs
storge.
Unfortunately, these switches does not support 802.3.ad lacp, (really I can't stack
them) but I've read about mode-alb and mode-tlb bonding modes.
I know,these modes are available in ovirt, but how is work that? Also how is safe? Are
there for HA or for load balance?
I've read some forums, where does not recommended these modes to use in ovirt. What is
the truths?
I would like to use only for storage-traffic, it will be separated from other network
traffic. I have two 10Gbe switches and two 10Gbe ports in my nodes.
Thanks in advance,
R
Tibor

Hello
If you have 10Gb ports you hardly need to use these aggregation in order
to have more bandwidth. 10Gb is enough for A LOT of things. Just use
bonding mode=1 (active/backup) if your switches don't support stacking.
Doing mode-tlb and alb is not always straight forward as mode 1 or mode 4.

No personal experience, but I would stay with what offcial docs say
https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.1/...
As you are writing about NFS storage, mode 5 and 6 should be supported
(non-virtual machine (bridgeless) networks)
Do you have any pointer about no-go recommendations?

Look here:
https://www.ovirt.org/documentation/admin-guide/chap-Logical_Networks/#bo...
"Important: Modes 1, 2, 3, and 4 support both virtual machine (bridged) and
non-virtual machine (bridgeless) network types. Modes 0, 5 and 6 support
non-virtual machine (bridgeless) networks only.¨
So both tlb (mode 5) or alb (mode 6) are fine only if you use them just for
the storage access but not for VMs.
Thanks in advance,
R

Thanks for the answers.=20
In this case the only question is: what is better for me? Mode 5 or 6?=20
In which modes how is fast the switching?=20
Until now I've use 802.3ad lacp on our old cluster. I did some tests and it=
was very fast. I know it is not same, but mode 5 or 6 how is safe?=20

Hi,
If you're looking at a simple ha bonding setup, why not using active-backup
(mode 1)?
We're using it in almost all our setups and switches toin backup interface
in 100ms when a link down is detected (Setting miimon=100).
Doesn't aggregate bandwidth but is a very good solution for high
availability whwn you can't configure lacp or a portchannel on switch side.

Hi,
Thanks for the answers.
In this case the only question is: what is better for me? Mode 5 or 6?
In which modes how is fast the switching?
Until now I've use 802.3ad lacp on our old cluster. I did some tests and
it was very fast. I know it is not same, but mode 5 or 6 how is safe?
Thanks

Tibor

Look here:
https://www.ovirt.org/documentation/admin-guide/
chap-Logical_Networks/#bonds-1
"Important: Modes 1, 2, 3, and 4 support both virtual machine (bridged)
and non-virtual machine (bridgeless) network types. Modes 0, 5 and 6
support non-virtual machine (bridgeless) networks only.¨
So both tlb (mode 5) or alb (mode 6) are fine only if you use them just
for the storage access but not for VMs.

Dear Luca,=20
Sorry for the very late reply..=20
I want to try out now your mentions.=20
Should I make an interconnect the two switches in active/backup mode?=20
Thanks!=20

Hi Demeter,
i don't know how the switch setup is done here, but as far as i know
they aren't stacked through interconnect.

Dear Luca,
Sorry for the very late reply..
I want to try out now your mentions.
Should I make an interconnect the two switches in active/backup mode?
Thanks!

Hi,
If you're looking at a simple ha bonding setup, why not using active-backup
(mode 1)?
We're using it in almost all our setups and switches toin backup interface
in 100ms when a link down is detected (Setting miimon=100).
Doesn't aggregate bandwidth but is a very good solution for high
availability whwn you can't configure lacp or a portchannel on switch side.

Dear Luca,
I've created a config with two 16 port 10GBe switches,those does not connected to each
other.
I have 4 hosts and 1 storage host. I don't know why, but I can't ping from all of
host to all of hosts.
For example I can ping from .1 to .2 but not .3! From .3 I can ping .4 but don't .1
:)
I don't know the cables how is connected to the switch, but I'm sure every host
connected to switches whit two inferface (one-to-one)
Thanks!
Regards,
Tibor
