<br>
Firstly, welcome to the Gluster community.<br>
<br>
Please visit <a href="http://www.gluster.org/community/documentation/index.php/GlusterFS_General_FAQ" rel="noreferrer" target="_blank">http://www.gluster.org/community/documentation/index.php/GlusterFS_General_FAQ</a>, which answers some of your queries about GlusterFS capabilities.<br>
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.,)<br>
that users of your application need etc, we will be in a better position to guide.<br>
<br>

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