There are issues about how you partition a giant hard drive like that. I forget just how many partitions your allowed but it is small compared to the size. I guess your the IT expert and you have REAL Experience to back your support for LVM.
Umm, AIUI the standard way of partitioning drives has no limit on the number of extended partitions one may create.
Uhm, not exactly. You get up to four primary partitions, one of which can be an extended partition. Inside that extended partition you can have as many "logical" partitions as you wish.
That is indeed my understanding. What one gets is essentially a linked list of Logical Volumes (correct terminology, but in the present context confusing, so I avoided it). The Logical Volumes have disc addresses which must be contained within the range of disc addresses as that specified in the PT entry corresponding to the extended partition. There is no essential limit to the number of Logical Volumes, though there may be only up to one extended partition. Floppy discs may have only one Volume. Primary Partitions have up to one Volume per partition. An Extended Partition has a number of Volumes which is limited only by the space necessary to contain the BPB and overhead per Volume. Otherwise, one may place as many Logical Volumes as one wishes within the Extended Partition.
