Specifications
The hybrid DDP series consists of the DDP12D, DDP16D, DDP24D and DDP24DF base systems.
The DDP base systems are modular Ethernet SAN Shared Storage Servers with the file system and metadata management build in.
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.
The specifications and models are shown below.
DDP Example Configurations
Some configured DDP examples are listed below. This is just to give an idea. DDPs can be configured almost any way imaginable.
SSD8 pack of 1TB SSDs
Most examples are configured with an SSD pack as cache plus spindles as a larger storage pool. Having an SSD cache is great for postproduction studios working for clients who may come up with different audio track count, video and film format requirements. No matter these requirement the total bandwidth given is always at your disposal. We tried to show this in the table.
This is because SSDs can be compared to memory. The preferred method here is that editors ingest, copy, play out and edit to and from the cache with file duplication automatically to the spindles. When a file is no longer in the cache it is taken from the spindles. Spindle performance is optimized as well. When two or more HD8 packs are installed files can be balanced between these packs partly averaging out the spindle seek time problem.
For situations with a lower then 1GB/s bandwidth requirement an SSD4 pack is sufficient.
Between 1 and 2,5 GB/s an SSD8 pack is needed.
Beyond 2,5 GB/s multiple SSD packs are required.
The pack capacity must be large enough so that the materials of active projects can fit in.
A cache is not the solution for everything. When a company plans to ingest much more data than the SSD capacity has available ingesting directly to the spindles would be a better choice. In that case caching can be from spindles to SSD.
In another situation the cache could be used only for audio or DPX with video predominantly using spindles.
Of course any other combination of SSD and HD packs and cards can be selected.
Such configured DDP tailored to the studio requirements can be used immediately. DDPs can be ordered partly populated so that additional HD and or SSD packs can be added later.
To find out which DDP would fulfill certain requirements just email us.
Values in the table are minimum values.
With SSD the number of streams of any format can be obtained by dividing 2000 (SSD bandwidth) by the bandwidth of your format.
For HD these values depend on audio, video and film formats used.
Single File System
No matter what storage configuration is chosen
Quota Management
Capacity is managed by quota
Increased Security
The DDP uses HTTPS and two factor authentication via the web interface
DDP EX Storage Arrays Specifications
When a DDP is full and additional capacity is needed or a DDP with only HD packs was ordered and now an SSD pack as cache is required a DDP16EX, DDP24EX, miniDDP24EX and DDP78EXR can be connected after installing an EX card in the DDP first.
To setup a scale out cluster to increase bandwidth beyond 6 GB/s and capacity beyond 1 PB another DDP can be integrated as well.
See the table below for the specifications and options.
