Storage Array Add-Ons and Upgrades
This chapter explains how to install add-on storage devices
1
and upgrade storage
arrays.
"Add-ons" are storage devices installed in an existing storage array without
changing its basic configuration. For example, you can add two RA90 disk drives
to the SA600–FA storage array, creating an SA600–HA storage array, without
moving existing storage devices or cables.
"Upgrading" a storage array involves changing the configuration by installing
enclosures in a storage array that previously had no enclosures. For example,
you can add SA7x enclosures to an SA600 storage array, creating an SA650.
During this procedure, storage devices already installed may have to be moved
and the SDI cables and power cords rerouted.
Add-ons can include one or more of the following devices:
• RA9x disk drives
• SA7x enclosures
• ESE50 solid state disk drive
• TA8x7 tape storage subsystem
The term "storage devices" is the collective name for all of these devices.
Specifically, this chapter explains how to perform the following:
• Unpack storage devices upon delivery and pack them for shipment or storage.
• Use a Digital-approved lifting device to install enclosures and large disk
drives.
• Install RA9x disk drives in the SA600/SA800, SA650/SA850, and SA900
storage arrays.
• Install ESE50 solid state disk drives in the SA900 storage array.
• Install SA7x enclosures in the SA550, SA650, SA850, and SA900 storage
arrays.
• Install TA8x7 storage subsystems in SA900 storage arrays.
• Upgrade an SA600 or SA800 storage array to an SA650 or SA850 storage
array.

Instructions for installing RA82 disk drives are contained in the SA482 Storage Array
User Guide.
