Fault tolerance

[Former Member]

Hi support,

there is an oss note certifying the use of fault tolerance vSphere 4.1 in production environment?

I have read the best practices for its use with MSCS, but I find no note

Thanks a lot

Hello,

unfortunately, we did not mention the use of VMware Fault Tolerance (FT) in an SAP Note so far. But it is supported.

The use case for FT is quite limited as FT only support Virtual Machines with 1 vCPU. In an SAP environment, we recommend using FT for the SAP System Central Services (SCS / ASCS). See the [SAP HA Best Practices Guide|http://www.vmware.com/resources/techresources/10031]. Note: this is not about using FT in connection with MSCS (which is not supported afaik), but rather descirbing alternatives.

Kind regards,

Hello Matthias,

I can't find the document http://www.vmware.com/resources/techresources/10031

Is it possible to have it?

Thanks and regards

There are two documents, but they are quite old. I'd ask VMware for an update.
