HP StoreOnce B6000 Series Manual page 28

NOTE: The following example illustrates how an HP D2D4000/4100 or 4300 Series Appliance
at the Data Center can easily support 20 libraries. However, if NAS shares were being used, only
the HP D2D4100 and 4300 Series would be able to support all 20 NAS shares, because of the
one-to-one mapping.
Remote Site 1 and Remote Site 4 each have one D2D Appliance and are running 4 projects.
They have configured 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 files.
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 4xxx series Target 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 4xxx 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 4xxx series Target Library.
