The standalone DDP series consists of the DDP12D, DDP16D, DDP24D, DDP48D and DDP48DF base systems

standaloneDDP series The standalone DDPs are modular Ethernet SAN Shared Storage Servers (2U, 3U, 4U and 8U) in a box with built in metadata controller.
Enterprise HD and SSD packs can be configured in Raid 5 or 6.
The DDP is called hybrid when both HD and SSD packs are installed. Both HD and SSD packs can be of different capacity. DDPs can come partly populated so that additional HD and or SSD packs can be added later. DDP48DF base system is required for very high bandwidths.


series DDP standalone

DDP conceptionally works with one virtual volume/Filesystem which holds folders with volume properties, so called Folder Volumes. Data itself is stored in Data Locations. Quota can be assigned to Folder Volumes to manage capacity. Also Data Locations can be assigned to Folder Volumes. When balanced is selected incoming media is distributed over Data Locations.
SSD Caching off or on plus cache mode are also properties of Folder Volumes.

With one SSD pack SSD Caching is possible thus eliminating seek time.
An SSD pack can be from 4 to 32 TB. The cache results in a large increase in performance. To increase bandwidth further load balancing is available. When storage is added later, data will be redistributed automatically.
With an EX card installed in the DDP additional storage arrays such as DDP16EX, DDDP24EX and DDP60EXR base systems can be added on the fly, also with automated data redistribution. With the upcoming V5 software other DDPs can be integrated on the fly as well. This results in Linear Scaling both in capacity and bandwidth. One DDP functions as master but with Parallel Data Access from to all DDPs.

DDP storage or complete DDPs can be added without users noticing.
There is no need for the administrator to make changes via the web interface, when Folder Volumes are set to balanced and caching. One web interface, one volume with folders and Folder Volumes: One Namespace.

All standalone DDPs use hardware Raid technology with redundant power supplies. Optionally 1GbE, 10GbE and 40/100 GbE ports can be added.

Additional Raid cards can be added when expanding the DDP with DDP16EX or DDP60EX JBODs.
SAS cards can also be added when using the DDP with LTO tape devices.
The supported operating systems are OSX, Windows and Linux. In order to guarantee the highest performance, an iSCSI initiator and AVFS client driver must be installed on each desktop. For clients wishing to use DDP as an NAS, no drivers are required.
