6-4 Compaq TaskSmart N2400 Administration Guide
Drive Arrays and Smart Array Controllers
Array Configuration Utility
The TaskSmart N2400 appliance can have as many as 56 physical drives in up
to four external storage enclosures. The drives are arranged in RAID array set
groups of up to 14 drives. Drive arrays distribute data across a series of hard
drives to unite them into one or more higher performance logical drives.
Distributing the data across multiple drives allows the data to be read and
written faster. Additionally, arrays can protect against data loss using a
number of protection schemes. The Array Configuration Utility (ACU) is used
to configure and expand data storage. The ACU is an easy-to-use graphical
interface for setting up drive arrays and fault tolerance, and adding storage.
Features of ACU
Graphical representation of drive array configurations
Wizards that help optimize array configuration
Express or custom initial configuration
Online spare (hot spare) configuration
Separate fault-tolerant configuration on a logical drive basis
