Sanity Check Performance SD-WAN

[squidgy]

Hello All

We've just moved our DR site to another branch, connected on SD-WAN to our head office both on upgraded 200/200 Mbps links.

We're investigating somewhat lower performance doing data backups and wanted to check what we should be expecting.

Checking the mx sizing guide for the MX64

Max site-to-site
VPN throughput 100 Mbps

Can someone confirm for me this is the SD-WAN limit per site? Assuming it is I need a higher tier mx?

Our backups are running at around 5MBs fyi - it could be a veeam issue of course.

100 Mbps should be perfectly reachable depending on the type of traffic. 5 Mbps instead of 100 seems very odd though.

Have you checked for duplex mismatches within that environment?

Hi Thanks for responding.

it was 5MBs not 5Mbps sorry I changed the nomenclature. 

i'll take a look but they're all set to auto-negotiate.

is 100 the max pipe we can expect on SD-WAN on MX64?

Yes 100Mb/12MB is the rated tunnel throughput . 

[squidgy]

right ok... 

bad practice I know, but checking everything (we have no traffic shaping) we're getting around half of the speed on the CBT backup in veeam. 

At least now I know the target we should be after. 

Ok so the branch mx is connected to a MS switch. I can see the duplex is auto 1Gbs. looks fine.

The source mx connected to a catalyst, that's also 1Gbps full duplex.

I don't think it's a duplexing issue but can see why you suggested it. 

is there anything else I can check?

@squidgy : Yes it supports 100 Mbps of course, For back on Veeam, can you tell me what bottle neck tooltip tell you on Veeam ?

[squidgy]

Inderdeep.

Bottleneck is network. 

We run a veeam proxy at both sites as per best practice.

You can do some iperf test between 2 locations to see what throughput you can get/expect.

@ww  that’s a great suggestion I’ll do that tomorrow or Monday. Thanks.
