Maintaining the JATP400 RAID Array
Redundant array of inexpensive disk (RAID) is a method of storing large amounts of application data
used for data redundancy, performance improvement, or both. There are different RAID levels designed
to increase data reliability and I/O performance.
The key concepts in RAID are:
• Mirroring—Copy data to more than one disk
• Striping—Split data across more than one disk
• Error correction—Redundant data storage to detect and resolve problems
The JATP400 appliance ships with hot-swappable hard disks to offer component redundancy. The
JATP400 appliance uses the RAID6 configuration. In RAID6, drives are duplicated for fault tolerance.
Replacing a Hard Drive on the JATP400 Appliance
To replace a hard drive from a driver carrier on the JATP400 appliance:
1. To remove a hard disk carrier:
a. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap
to one of the ESD points on the chassis.
b. Press the eject button on the right side of the disk slot to release the hard drive. See
