D-20 Understanding Drive Arrays

Disk Drive Upgrades

Additional storage space may be obtained with the same number of physical
drives in a fault-tolerant configuration by replacing these drives with others of
higher capacity. By replacing the drives one at a time, the data on the new
drive is recreated from redundant information on the remaining drives. After
each new drive has been rebuilt, the next can be replaced. After all drives
have been replaced and rebuilt, the additional capacity on each drive can be
utilized by adding a new logical drive. Array Configuration Utility will
automatically recognize the unused space and guide you through the
procedures to make use of it.
