2 Installation
Setup
The installation of your DEU disk array subsystem is
essentially a three-step process: the subsystem is setup
and its components installed, the cabling is completed
based on the supported configurations, and the array is
then configured.
The DEU is designed with an open architecture that
allows for many possible combinations of cabling
schemes. Due to the inherent limitations of sampling
all of the possible configurations, we will provide a few
of the most typical cabling schemes and implementation
of the configuration modules.
Additional configurations are available through the use
of Ultra Extender or Differential Converter Option
cards. Refer to Appendix D for information specific to
each card and configuration.
This chapter is divided into two sections: Setup and
Cabling Configuration. The Setup section provides the
instructions for assembling the rack-mount subsystem,
and installing the hardware components (controllers,
disk drives, power supplies, etc.,) for both rack-mount
and deskside tower-based subsystems.
The Cabling Configuration section contains samples of
cabling schemes and configuration modules. If your
desired configuration is not shown in the samples, refer
to the example most similar and follow the cabling
topology schemes expanding the example to fit your
needs.
When configuring the array, refer to the Ultra S2S
RAID Controller User’s Guide provided with your
controller.
If you are setting up a rack-mount subsystem continue
with “Rack-Mount Subsystem Assembly” described later
in this guide, otherwise skip to “Component
Installation” also described later in this guide.
