How many OST's are behind that OSS? How many MDT's behind the MDS?

Hmm. That is an odd one from a quick thought... However, IF you are planning on growing and adding OSSes/OSTs, this is not a bad way to get started and used to how everything works. It is basically a single stripe storage. If you are not planning on growing, I would lean towards gluster on 2 boxes. I do that often, actually. A single MDS/OSS has zero redundancy, unless something is being done at harware level and that would help in availability. NFS is quite viable too, but you would be splitting the available storage on 2 boxes.

The vendor has proposed only 1 MDS and 1 OSS as a solution. The query we have is that is this configuration enough , or we need more OSS? The MDS and OSS server are identical with regards to RAM (64 GB) and HDD (300GB) Thanks Majid _______________________________________________ lustre-discuss mailing list lustre-discuss@lists.lustre.org<mailto:lustre-discuss@lists.lustre.org>http://lists.lustre.org/listinfo.cgi/lustre-discuss-lustre.org
