Linux clustered filesyetems, GFS, etc.
Posted on 2006-05-15
I have the following dillema:
I have to connect 15 RedHat enterprise servers to storage device using ISCSI. Because files from this storage device will be simultaneously accessed from many servers, I have to use some mechanism for the file locking and sharing. I know that I can use GFS or NFS, but NFS is not an option due a to a slow performnace. GFS is a good option, but it's expensive - 2200$/server. I could you open source version of GFS for free, but I am not sure if I want to do that in production environment.
Could you recommend any other free/commercially available products or standard Linux toold , I could use for this setup?
Have anyone tried to use OpenSource GFS in production, any issues ?
What about EVMS ? Is it just a management tool, or it also can help me in my situation and provide file locking and sharing facilities ?
One more thing: we have a relatively limited budget and can't afford to spend more than 500$/server
Thanks a lot.
