EVMS does not place any limitations on the number of segments that can be 
created on a single disk. However, the Linux partitioning code (and probably 
fdisk), do have limitations. An IDE disk can only have 63 partitions, and a 
SCSI disk can only have 15 partitions.

If you are only using the /dev/evms/[hs]d??? devices, then you won't need to 
worry about the Linux limitations. However, if you intend to create the 
segments in EVMS and then go back to using the Linux partitioning code 
(/dev/[hs]d??? ) in the future, you will need to abide by the above 
limitations.
