The scalable redundant DDP series are modular Ethernet SAN Shared Storage Servers.
For high bandwidths DDPHeadF instead of DDPHead is required. These storage arrays can be lled with HDs and SSDs with various capacities. The DDP consists of one or two DDP Heads who act as the metadata controller and up to 20 units of non-redundant 16EX and 24EX or fully redundant 16EXR, 24EXR or 60EXR storage arrays.

The DDP consists of one or two DDP Heads who act as the metadata controller and up to 20 units of non-redundant 16EX and 24EX or fully redundant 16EXR, 24EXR or 60EXR storage arrays.

With 20 x DDP60EXR and 10TB HDs the total capacity can be 12 PB. A setup consisting of two Heads 16EXR, 24EXR and/or DDP60EXRs is fully redundant, fully hot swappable with no single point of failure. The realistic, typical use case bandwidth when the DDP Heads are used active-active can be 12 GB/s. The storage arrays can be lled with combinations of HD and SSD packs of various capacities, con gured as RAID5 or RAID6. They can be partly populated and further populated at later date.

When an SSD pack is installed SSD caching can be used thus eliminating seek time resulting in a large increase in performance. To increase bandwidth further load balancing is used. When storage is added at a later date the data will be redistributed automatically. Storage arrays such as DDP16EX, DDDP24EX and  DDP60EXR base systems can be added on the fl y again with automated data redistribution. DDPs can also be added on the f y as well (upcoming V5software) resulting in both linear scaling in capacity and bandwidth to 120GB/s and 120 PB.

DDP conceptionally works with one virtual volume/fi lesystem which holds folders with volume properties, so called Folder Volumes, the metadata. Data is stored in Data Locations, the data. Quota can be assigned to Folder Volumes to manage capacity. Also Data Locations can be assigned to Folder Volumes. When balanced is selected, incoming data is distributed. When an SSD pack is purchased also caching can be assigned to Folder Volumes. Storage, any DDP storage or DDPs themselves, can be added without users noticing and for the administrator without having to make changes in the web interface. For administrators who wish full control the Storage Manager page in the web interface is available.
