The controller named Smart Array 6400 Controller (if present) is used for all
externally SCSI attached storage.
Caution: On the Smart Array 5i controller there are two logical drives pre-configured
under Array A. These two logical drives are configured for the NAS operating system and
should not be altered.
Express Configuration
Select Express Configuration to be asked a few simple questions and allow the
controller to be configured automatically. The Express Configuration is the easiest
and fastest way to configure a controller and will provide the most reasonable
configuration possible.
Configuration Wizards
Select Configuration Wizards to configure a controller through a series of wizards,
which provides a guide through the configuration process. Choosing Configuration
Wizards is not the fastest or easiest way to configure a controller, but it does offer
more control over the configuration and provides for a more individualistic setup.
Standard Configuration (default)
Select Standard Configuration to quickly configure a controller. Choosing
Standard Configuration is the fastest way to configure a controller but requires an
intermediate to advanced level of knowledge concerning storage. The Standard
Configuration path offers the least amount of help or step-by-step guides and does not
provide a FAQ panel, assuming the user knows exactly what they would like to
accomplish and are very familiar with the concepts required to complete the task.
The default method is the standard configuration method. The steps that follow are for
creating an array using the standard configuration mode.
The Fault tolerance level depends on the amount of disks selected when the array was
created. A minimum of two disks is required for a RAID 0+1 configuration, three disks for
a RAID 5 configuration, and four disks for a RAID 5 ADG configuration.
