14 Capacity Upgrade

Introduction

The Capacity Upgrade Kit increases the storage capacity of your HP D2D4112 Backup System. The
Capacity Upgrade Kit is installed on rails as a separate shelf immediately above or below the HP
D2D4112. Shelf is used as a term within the D2D Web Management Interface to identify the 12–disk
physical storage space provided by the HP D2D Backup System (Shelf 0) and the Capacity Upgrade
Kit (Shelf 1). This is also displayed pictorially on the Summary page of the Web Management Interface.
The following example shows the Summary screen when the HP D2D Backup System has a single
shelf with 12 disks.
The following example shows the Summary screen after the Capacity Upgrade Kit has been installed
and the HP D2D Backup System has two shelves with 24 disks.
