Slow Replicas | Different VLANS | ESXi

[edelucas]

Hi people; we used a VLAN for management (esxi) and another VLAN for VM Network; Replicas take to much time with a rate to low. When we used the same vlan replizas were very fast. Any light at the end of the tunel?
The scenario is simple; to esxis hosts. The nics of the esxis are in trunk mode (in the switch) and we split them via port groups in the esxi networking for the different vlans.
Thanks for all.

HI,

What is the bottleneck reported for this job in both cases?

Thanks!

Hi and thanks; for differents vlan it says "source" and dont pass over 3MB/s. The Veeam proxy is localed in a different vlan (vm network) instead the vlan for management.

Hi Erick!

I would say that network configuration might be a bottleneck as long as proxy reads data in network mode.

When we used the same vlan replizas were very fast.

Looks like this test is illustrative enough. Any chance to setup a dedicated proxy in the same vlan?

By the way, you may want to consider a usage of Virtual Appliance mode if you have a virtual proxy.
Processing rate of reading data from source in this mode doesn't depend on network configuration.

Thanks!

But do you recommend the proxy in the same management vlan? I can do the test

[edelucas]

Well this is the config that we have:
ESX1

VSwitch0
Management Network (VLAN A)
Active nics (1,4)
Standby nics (2,3)

VM Network (VLAN B) -> where proxy vm is located and 3 more vms
Active nics (2,3)
Standby nics (1,4)

The same for the second host.

switch#1
P1-> esx1 nic1
P2-> esx1 nic2
P3-> esx2 nic3
P4-> esx2 nic4

switch#2
P1-> esx2 nic1
P2-> esx2 nic2
P3-> esx1 nic3
P4-> esx1 nic4

Both switches are stacked

Thanks for all...

Hi Erick!

I thought the test was already done because you said that replications were fast when the same vlan was used.
Anyway, let's do this test.

Don't forget about the possibility to use other transport modes such as for example Virtual Appliance, read speed might be significantly faster.

Thanks!
