Genesys and VMWare

[JeffreyT]

Hello everyone,

I'm currently integrating a 8.1 Genesys environment in HA mode on a VMWare platform. So far the only information I had was found in the Genesys documentation known as "Hardware Sizing Guide", which only points out general information such as :
[list]
[li]ESX version[/li]
[li]CPU overhead in regard to physical servers[/li]
[li]...[/li]
[/list]

Our customer is using ESX Clusters and performs VMotion and VEEAM backups on a regular basis. It seems that some of these operations have very bad side effects on the Genesys environment causing some unecessary switchovers and in some case unexpected application crashes (ConfigServer & UCS are the most problematic issues).

Would anyone know of information stating what can and what can be done on VMWare when hosting Genesys software ? I know, this is a very general topic, but I'm trying to start from what was documented on Genesys Sizing Guide ;-)

Thanks for reading, and for your help if you have any information.

Cordially
Jeffrey

Had a similar issue with a customer. The problem was that VMWare did a 1sec link lost and that was enough for Genesys to switchover (as designed).
They did a different approach on Genesys VMwares and we also asked them to do that only when we did a change on the machines as what is really important are the DBs backup. You can restore a VMWare with same components of any date and will work.

Thank you for this quick answer.
This was exactly what my suggestion to the customer was (very logical in deed).

Also I agree with fact that switchovers are normals in such cases, what is problematic however is that some of the components crashes in this switchover.
Not all of course, but I'm having difficulties with ConfigServer & UCS at this time...

However, our customer is now challenging the fact that Genesys on VMWare is really supported.
I'm trying to find written information which could be a sort of "Best Practice Guide" in this sort of environment.

Crashing? Urmmm I also did had issues with URS but due a bug on the application itself.
It is supported by VMWare (works) but never says nothing about that specific method of doing a backup. I do know VMWare gave an alternative method which is totally transparent for high critical applications. It is up to VMWare to propose a solution, not Genesys side...as VMWare can vary on a lot of architectures...

Hi Jeffrey,

It is not exactly what you're looking for but it might be helpful - Technical Paper / Running Genesys Inbound Voice Routing with VMware vMotion and HA on vSphere 4.1 and vSphere 5.0 ([url=http://www.vmware.com/resources/techresources/10253]http://www.vmware.com/resources/techresources/10253[/url])

I'd look at your VMWare set up.

I run a large SaaS model Genesys 8.1 platform with hundreds of VMWare guests and have never had an application crash or switch over due to VM's moving around.
