A NetWare volume is the highest level in the NetWare file system. It consists of up to 32 segments, which NetWare automatically numbers from 0 to 31. When you create a volume, the volume consists of one segment that is the size you specify. To increase the size of the volume, you add additional segments to the volume. The size of the volume increases by the size of the segments that you add.
NetWare volumes on a PC server can spread across multiple disks.
