Multiple Disks

Hi,

We are configurerinf an application setup where in we need very large file system. We have four controllers and in each set there are 18 GB X 5 disks. We are using VXVM software for disk partitioning. We used to create many small size partitions for this purpose. WHat Happens if we create one big volume? In this case if one controller fails what happens? Is there any performance improvement? Can you post the procedure how to do this please.

Thanks,

Sreeram.
