GPU Tesla K20 on SL390?

[ajdser]

I have a SL390 server with a GPU Tesla M2090.
Now I plan to purchase a GPU Tesla K20 to install this server.
However, I read in the HP documentation that the SL390 does not support the K20.
I would to know if this is just a recommendation of HP or is there some technical limitation (and what is) that prevents K20 working in SL390.
Thanks.

Review section “Supported Servers and Workstation Blades” in the  NVIDIA Tesla GPU Modules for HP ProLiant Servers QuickSpecs which indicate that this GPU is only supported by  HP ProLiant SL250s Gen8 Server and HP ProLiant SL270s Gen8 Server series. Link to the GPU’s QuickSpecs:

The HP ProLiant SL390 G7 Server series does not support this GPU.

Vijayasarathy, thanks for your answer.
And you know why the SL390 does not support GPU K20?
I do not understand what the technical reason that prevents K20 work in SL390, mas I would like to know what the reason is.
Thank you in advance a possible explanation.
