[Ocfs2-users] Quantifying OCFS2 network traffic...

[Peter W. Morreale]

Hi all,

I'm trying to understand and quantify network traffic for a 32 node high
performance OCFS2 installation.   Part of what I'm doing is attempting
to size the network hardware requirements.  To do this I need some help
understanding the kinds and amounts of traffic generated during "normal"
use.  

Once populated, the system will have a very high READ to WRITE op ratio.
I need to optimize OCFS2 (both hard/software-wise) for this use.

Conceptually, it would seem that DLM would be responsible for most of
the network traffic associated with ocfs2.  Correct?  Is DLM traffic the
same for a READ as for a WRITE?

Does ofcs2 itself send messages for reads and/or writes in normal use?  

Any metrics known relating IO size to network traffic?  Guesses? 

If I'm using a 10GigE network, would I have a need for adding another
NIC and bonding?   

Thanks,
-PWM
