1.1.1 What Happens When You Mount a Traditional Volume

When you boot a NetWare server, each Traditional volume is mounted, meaning the following:
As the Traditional volume is mounted, the FAT and DET fill cache buffers in the server memory.
The more files and directories in the volume, the longer it takes to mount. If a Traditional volume
fails to mount, it might be because you have run out of server memory.

1.1.2 Traditional Volume Objects in eDirectory

In Novell eDirectory
are leaf objects that represent a physical volume or logical volume on the network.
The Volume object's properties contains the following information:

1.2 Traditional Volume Segments

A Traditional volume can use space from up to 32 logical or physical devices. The volume can grow
up to 1 TB in total size for all segments combined. Each segment of space is taken from a NetWare
partition. The segments of space are automatically carved by the management tools when you create
the volume.
The advantage of distributing a volume's segments across multiple server disks is that different parts
of the same volume can be read from or written to concurrently, which speeds up disk I/O.
Because of hardware restrictions, a hard drive can contain up to four NetWare partitions, or three
NetWare partitions and one DOS partition. (The hard drive that contains the sys: volume also
contains a DOS partition.)
Each NetWare partition can contain up to eight Traditional volume segments. Thus, a single server
disk can contain up to 32 volume segments (4 NetWare partitions with 8 segments each). A single
NetWare partition can contain up to eight Traditional NetWare volumes, each with a single volume
segment.

The volume becomes visible to the operating system.
The volume's File Allocation Table (FAT) is loaded into memory.
A single block of data in the file takes up one entry in the FAT. Because of this, volumes with a
smaller block size require more server memory to mount and manage, and it takes longer to
mount the volume. However, if most of your files are small, a large block size wastes disk
space.
The volume's directory entry table (DET) is loaded into the server memory.
