Hello Tarkeshwar,

GlusterFS uses file level and range locks based on the operation. 

With the description you have given below, Gluster definitely seems to be the 
right choice for your workload. I recommend that you should try a proof of 
concept with Gluster under your application work load to experience the 
benefits. 

You can always reach out to GlusterFS community (this mailing list) for any 
queries and help regarding the same. 

Regards
Nagaprasad.

Hello Tarakeshwar,

Firstly, welcome to the Gluster community.  

Please visit 
http://www.gluster.org/community/documentation/index.php/GlusterFS_General_FAQ, 
which answers some of your queries about GlusterFS capabilities.
If you could share with us the nature of I/O workload your application is 
generating, the performance need of your application, type of client access 
(NFS, CIFS etc.,) 
that users of your application need etc, we will be in a better position to 
guide.

Nagaprasad

Hi all, 
We have a product which is written in c++ on Red hat. 
In production our customers using our product with Veritas cluster file system 
for HA and as sharded storage(EMC). 
Initially this product was run on only single node. In our last release we make 
it Scalable(more than one nodes). 
Due to excessive locking(CFS) we are not getting the performance. 
Can you please suggest Gluster will resolve our problem as it is distributed 
file system. 
is Gluster POSIX complined? 
Can we use it in Production? Pls suggest. 
If any other file system please suggest. 
Regards 
Tarkeshwar

Hi Nagaprasad,

Thanks for reply.


*Nature of I/O workload your application is generating:*
It is very high. Our product woking on files. It is collecting data(multi
process and multi threaded) from remote nodes and then processing it and
then it sending it to remote locations.
our Execution engine runs the processing busines logic. So huge no of
open,read,write,rename calls in the our code per second.

recently we made it scalable as well, so our business logic runs
horigontally from multiple nodes. we are collecting it in common directory
and reading it from same directory for processing.

We are using Veritas cluster file system. It is locking on directory level.
Since same directory accessed from multiple nodes. There is a delay in
processing. further it reducess performance drastically.

For improving performance we made some changes in our application by
breaking the direcotories for collection and processing.
By this we got performance improvement.

We feel if we change our file system we will get more improvement. Please
suggest.


Regards
Tarkeshwar
