Hi Ophir,
I had inquired previously about such functionality for ESXi 5 and referenced this Mellanox link - http://ir.mellanox.com/releasedetail.cfm?ReleaseID=601497
There are also other documents based on ESXi 4 that has the same functionality, but also includes screenshots - http://www.mellanox.com/related-docs/prod_software/IB_OFED_for_VI_3_5_and%20vSphere_4_installation_guide_1_30.pdf
I have yet been able to get this functionality to work in ESXi5. Do you know if it does work? Thank you.
Matt
