No. What it means is that the largest single volume in your diskpool can be 1TB. You could have, say, 30 volumes @ 500GB per volume, making a total storage pool size of 15TB. Every two volumes would be in their own filesystem. If you're using a disk farm as your primary storage pool, fault tolerance is strongly recommended. RAID0 and RAID1+0 would be more expensive; RAID5 might make more sense, as long as you were using a proper monitoring system (properly set up) to watch the health of your disks. Are you using CACHE=YES in your proposed disk solution? -- Mark Stapleton ([EMAIL PROTECTED]) Berbee Information Networks
