Chapter 4 Disk Configurations
Your storage system supports the following types of disk configurations:
Linear —A linear configuration is similar to using multiple hard disks in a
regular computer. Each disk is an independent entity, and the data on it is
self-contained. You can add or remove the disks without affecting the other
disks. All the available disk space is used for data.
If your storage system has only one disk, you must use a linear
configuration. However, you can use a linear configuration for two, three, or
four disks as well.
RAID 0
—Instead of writing all the data to one disk in a linear fashion, some
bytes are written to one disk, and other bytes are written to another.
Performance is faster because reading and writing activities can occur on
multiple disks simultaneously. All the available disk space is used for data.
For RAID 0, your storage system must have at least two disks. However,
you can use RAID 0 with three or four disks as well, and the disks can be
any size.
