Chapter 8:
Configuring a Second HDD for RAID
Introduction
This chapter discusses how to add a second hard drive and configure a RAID system
using the
Intel® Rapid Storage Technology .
Note:
For information about how to install disk images on a system that is already
configured as a RAID system see the I nstalling Disk Images on a RAID System chapter.
The Intel® Rapid Storage Technology provides new levels of protection, performance, and
upgradeability for the 7616 platform. Whether using one or two hard drives you can
take advantage of enhanced performance and lower power consumption. When using
two drives you can have additional protection against data loss in the event of hard
drive failure.
Valuable digital memories are protected against a hard drive failure when the system is
configured for one of the fault-tolerant RAID levels:
RAID 1 or RAID 5 . By seamlessly
storing copies of data on one or more additional hard drives, any hard drive can fail
without data loss or system downtime. When the failed drive is removed and a
replacement hard drive is installed, data fault tolerance is easily restored.
Configuring a RAID System
RAID systems can be installed on the RealPOS 72
XRT
if the 7416-F266 Dual 2.5" Hard
Disk Drives feature is present, which contains two 250 GB SATA hard disk drives. This
feature is also available in kit form (7403-K266) to upgrade terminals that are not
configured with the dual drives feature.
