man lvm中关于lvm限制的一段，理解上真困难，哪为帮我翻译一下

Currently up to 99 volume groups with a grand total of 256 logical vol-
       umes can be created. The limit for the logical volumes is not caused by
       the LVM but by Linux 8 bit device minor numbers.

       This  means that you can have 99 volume groups with 1-3 logical volumes
       each or on the other hand 1 volume group with up to 256 logical volumes
       or anything in between these extreme examples.

       Depending  on  the  physical extent size specified at volume group cre-
       ation time (see vgcreate(8) ), logical volumes of between a maximum  of
       512  Megabytes  and 1 Petabyte can be created.  Actual Linux kernels on
       IA32 limit these lvm possibilities to a maximum of 2 Terabytes per log-
       ical  and per physical volume as well. This enables you to have as much
       as 256 Terabytes under LVM control with all possible 128 scsi disk sub-
       systems.  You can have up to 65534 logical extents (on IA32) in a logi-
       cal volume at the cost of 1 Megabyte in kernel memory.   Physical  vol-
       umes can have up to 65534 physical extents.
