[cisco-voip] Vmware Supported by Cisco...Thoughts??

I think VMWare (especially the ESX verison) has definate advantages, even in a production environment. As far as I know the underlying OS is as transparent as it can get to the client O/S and application. There are many educational institutions which are experimenting with this sort of datacentre. I'm not sure the single point of failure argument stands either, from what I gather, setting up two ESX servers with shared data stores is quite fault tolerant. Then again, I'm sure we'd all get at least two VMware servers, seperating our pubs and subs equally.

I think Cisco should at least investigate a version of CallManager, et al, for the lab so that we can effectively and effeciently build our labs to properly support our deployments. There are many institutions which lease their servers so when they replace them they don't have anything to migrate to the lab.

Then again, I've been waiting a long time for CSCdr03425 to be fixed, so I doubt VMware support is going to be done anytime soon. ;)

  I am not privy to any discussions in Cisco regarding vmware but I can give you my opinion on why vmware is not supported today. I am also not aware of any discussions for future support and would guess that it is not on the roadmap. Even if we were to open up support just for demo/lab purposes we would end up with customers deploying in a production environment and expecting support when things don't work as expected.

  For us to support vmware we would need to verify the operation and performance of each version of CallManager (possibly including Service Releases and Engineering Specials) on vmware. This would, at a minimum, double our testing effort which would cause major delays in getting product and updates out for our customers. In addition we would need to create design guidelines for using vmware which would have an impact on product release timeframes. 

  From a TAC support perspective; vmware would increase the complexity of troubleshooting operational and performance issues. Currently we support the CallManager OS. Adding vmware to the mix would greatly increase the complexity of now having to look at vmware and the host server's OS as potential issues.

  Since we don't test vmware we can't provide nor guarantee any sort of performance levels for running CallManager on vmware. I would highly recommend NOT using vmware in a production environment.

  Again this is just my opinion and not official word from Cisco :-)

    Thanks for the response Kevin.  Other than for the obvious reason I stated earlier.  Why is everyone on this site installing 4.1.3 and etc. on Vmware if it is not supported?  When will Cisco support Vmware?

    Cisco does not support VMWare for CallManager, etc. The only Cisco supported installations are the ones described in the docs on CCO.

      Let's take this communication in another direction…  This is very interesting to read all the comments and questions about Vmware.  When we purchased our environment from Cisco.  We had problems with TAC support after the install because our environment was not standard in their opinion.  I have two questions: 

      1. Does Cisco support the Vmware environment?  

      2. And if so, what are the parameters for support and guidance? 

      3. And, what products do they support, e.g. Windows? 

      This could save us $$ when it comes to replacing servers! 

      Thanks.
