[ogfs-users]ogfs over firewire

Hi all

We currently have a small cluster (10 pc) for rather small compilation jobs. We actually use NFS, and the performance is very bad: the jobs are waiting for data to be fetched from NFS, and the remote cpu utilization ratio is less than 5%.

That’s why I thought about a low cost solution: OGFS over firewire. I was compiling the kernel with ogfs and firewire driver, then I could see in the firewire driver sources that there is a limitation with oxford firewire to ide bridges: it allows only 4 concurrent logins with the oxford 911, and LaCie told me that the firewire800 drives using oxford 922 are limited to 2 nodes connected to it. Oxford chipset are used on a vast majority of firewire drives.

Has anybody tried ogfs with about 10 to 20 nodes connected to a firewire drive?

Anybody knows a firewire drive with no such limitation ?

I would like to have up to 40 nodes connected. Do you think that OGFS would perform better than lustre or coda?

Thanks for your help.
