Hi, We have plans to build a 30TB aprox. data storage using a set of SAN boxes configured as RAID 5, our understanding is that using LVM2 with Red Hat 4 and our 64 bit AMD opteron processors shall allow us to do that. Our concern is to know in advance if our approach is wrong or even better if somebody else has been successfully taking the same road. Documentation tells us that the limit is in the order of the 8 Exabytes (8TB for IA-32) but this not enough as this is a go / no go decision. Thanks for any help or pointer to a similar rig. Cesar O. Pablo PS: By the way, we already discovered that the max. physical partition cannot exceed 2TB with our Hardware.
