Alfonso,
You are correct in the fact that the *architecture* of a Lustre file system greatly
influences the performance - both good and bad.
That said, the MGS is very low in terms of resources used or required. So, rather than
thinking of splitting the MGS and MDS in terms of performance, it is better to think of
splitting them in terms of overall functionality within the Lustre file system - and in
that regard (features, etc.) it is better to have the MGS on one node and the MDS on
another node.
As for architecting to get a high level of performance, please see:

Subject: [HPDD-discuss] performance split mds mgs
Hello,
I must implement a new lustre file system and optimize it to get a high level of
performance. I wonder: can I get more performance, If I split the MDS and the MGS in two
different machines?
Thanks!!!
