I have a small Mellanox SAN for an ESXi lab. I've been running ESXi 5.1 on it, so I decided to experiment with 5.5 and 6.0 to get experience. When I went to the drivers at http://www.mellanox.com/page/products_dyn?product_family=36 it said:
NOTE: To obtain the driver for ESXi 5.X v1.8.2.4, please contact support@mellanox.com.
So, I contacted support, and got this reply:
According to our records, we could not locate any valid contract for you.
How does one get the drivers legitimately without a support contract for noncommercial purposes?
