Preface

This manual describes how to maintain the hardware for PS5000 storage arrays.
Each array contains hot-swappable power supply and cooling modules, eight or
sixteen RAID-protected disks, and single or dual hot-swappable control modules.
With one or more PS Series arrays, you can create a PS Series group—a self-
managing, iSCSI storage area network (SAN) that is affordable and easy to use,
regardless of scale.

Audience

This manual is designed for the administrators responsible for maintaining
PS5000 hardware. Administrators are not required to have extensive network or
storage system experience. However, it may be useful to understand:
• Basic networking concepts
• Current network environment
• User disk storage requirements
• RAID configurations
• Disk storage management
Note: Although this manual provides examples of using PS Series arrays in some
common network configurations, detailed information about setting up a
network is beyond its scope.

Organization

This manual is organized as follows:
• Chapter 1, Basic Storage Array Information, describes the array front and
back panels, how to interpret LEDs, how to use an electrostatic wrist strap,
and how to shut down and restart an array.
• Chapter 2, Maintaining Disks, describes how to install and remove disks.
• Chapter 3, Maintaining Control Modules, describes how to install and
maintain control modules and replace the compact flash card. It also describes
the best way to connect network cables to control modules for high
performance and availability.
• Chapter 4, Maintaining Power Supply and Cooling Modules, describes how to
install and remove one of the modules that provides both power and cooling.
