that requires replicating; two have two libraries each. This means that 8 libraries are required on the
Target Appliance in the Data Center.

• Each HP D2D400x Source Appliance can support up to 16 Source Appliances. Each library on the
Target Appliance may be mapped to a maximum of 4 libraries on each Source Appliance. In other
words, up to four Source Libraries may be mapped into a single HP D2D 4000 Target Library.
• Each HP D2D41xx Source Appliance can support up to 24 Source Appliances. Each library on the
Target Appliance may be mapped to a maximum of 4 libraries on each Source Appliance. In other
words, up to four Source Libraries may be mapped into a single HP D2D 4100 Target Library.
For example: a research establishment has 5 remote sites, and a total of 10 Source Appliances. The
HP D2D400x or 41xx Series Target Appliance at the Data Center can easily support all 10 Source
Appliances.
• Remote Site 1 and Remote Site 4 each have one D2D Appliance and are running 4 projects. They
have con fi gured a Source Library for each project on their HP D2D. Each set of 4 libraries can be
mapped to a single library on the Target Appliance at the Data Center. The ability to replicate slots
from up to 4 libraries on Source Appliances into a single Target Library on a Target Appliance allows
for some additional level of data deduplication across the backed up data; for example, common
operating system fi les.
• Remote Site 2 has two D2D Appliances, each with two Source Libraries. We can map the slot
mapping collections from those libraries into a single HP D2D 400x Series Target Library. . Source
Appliances 3, 4, 5 and 6 each have one library;
• Remote Site 3 has two D2D Appliances, one with three Source Libraries and the other with one
Source Library. Again, we can map the slot mapping collections from those libraries into a single
HP D2D 400x Series Target Library.
• Remote Site 5 has four D2D Appliances, each with one Source Library. We can map the slot mapping
collections from those libraries into a single HP D2D 400x Series Target Library.
