Ocfs2 devel - May 2016 - OCFS2 benchmark questions

Hello Joseph, Junxiao and All,

I got some benchmark related questions, but due to hardware limitation in our
local lab, we have not enough information to answer the questions.
Could you help to look at the questions, if you ever did the related testings in
your sites.
1) How many nodes can OCFS2 cluster scale out to? theoretically, the answer is
32. but who ever did the testing with the maximum number of nodes? second, too
many nodes will impact the performance, or not?

2) Who can help to share OCFS2 benchmark information/data in the physical
environment? e.g. node hardware information, back-end storage information, IO
read/write data, IOPS/IO throughput. etc.


Thanks
Gang

The limit is 255, but we didn't advise using more than 32 nodes. More
nodes impact performance for sure.

Thanks,
Junxiao.
