D2D Defined

The entry level D2D100 series Backup System meets the needs of small businesses as a low-cost
solution that does not incorporate deduplication technology. The D2D2500 is well suited for remote
and branch offices and small IT environments, while the more powerful D2D4000 and D2D4100 are
designed for medium-sized companies and small data centers. The D2D2500, D2D4000 and
D2D4100 products include HP Dynamic deduplication, which provides low cost and flexibility to
meet the needs of smaller IT environments.
All HP D2D products are are RAID disk-based backup devices using serial ATA drives. All D2D devices
include iSCSI virtual library interfaces over LAN, and the D2D4000/4100 have the option of adding
a Fibre Channel interface to broaden connectivity. The D2D emulates a variety of physical tape
libraries including the tape drives and cartridges inside the libraries. D2D accommodates mixed
IT-platform and backup-application environments. For more insight into mixed-IT solutions and
environment analysis, visit the HP StorageWorks Enterprise Backup Solutions web site:

The virtual tape solution uses disk storage to simulate a tape library. That is, a virtual library simulates
libraries with tape drives and slots as if they were physical devices. Backup servers see the virtual
libraries as physical libraries. Because you can create many more virtual libraries and drives than
you have physical tape drives, many more SAN-based backups can run concurrently from the
application servers, reducing the aggregate backup window. After the backups are complete, the
tape-offload feature or the data protection software can migrate backup data from the virtual media
to physical tape for off-site disaster protection or long-term archival. This migration to physical tape
can happen outside of the backup window at whatever time you determine will work optimally with
your backup environment. The deduplication-enabled replication feature also provides the ability to
create a second off-site copy in another D2D via a TCP/IP link.
