We are running a qmail/vpopmail 'cluster' with the backend storage shared via NFS from a Solaris 8 system. Our mail system delivers approximately 400K messages a day on a disk system that has 30 10K drives in a RAID 10 setup. This has worked fine for us for a few years, but we are now finding that the system's performance may not be able to accomodate future growth for much longer.
I was wondering if anyone is experiencing this same problem, and what different approaches are being used to solve it. Thanks in advance, Duane Wylie
