Is anyone running in this configuration? I am working to get a lab ESXi 5.1 environment up and running to try this configuration myself but this probably won't happen for about 2 weeks. Hopefully I can get a confirmation in that time.
I contacted Tech Support and this was the response I received:
Hello xxxx,
My name is Nathan xxxx and I have been assigned to your case. The best I have been able to find regarding supported versions of ESXi is the following:
https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ve-supportedhypervisormatrix-1-0-0.html
It will get updated as new versions are officially supported. Depending on the changes in the ESXi versions, 5.1 may work without any changes, but according to our documentation it is not yet officially supported. I was not able to find a timeline when it will be officially supported. You might try our sales department and see if they have an information that I otherwise do not have access to.
Please let me know if you have any further questions regarding this case and I will do my best to answer them. I hope you have a great day.
Best regards,
-Nathan
