DVS presents own SAN solution (17/9/2004)
At IBC DVS is launching its own SAN storage solution: "DVS-SAN" (Storage Area Network). It consists of fiber channel disk arrays with an optimized RAID controller. With this addition to its product line-up DVS fulfills the need of post-production companies, whose workflows are based on central storage. DVS-SAN has been developed to cater for the real-time transfer of film 2K and HD video sequences requiring high data-rate and data-access capabilities.
The advantage for post-production companies in using SAN technology is that several workstations can access the same data concurrently. For example: while one workstation is writing to the DVS-SAN, another can start working with the data, even before all the data has been transferred.
The workstations connected to the DVS-SAN Ð for example the CLIPSTER editing system or the Pronto2K disk recorder Ð can play concurrently video clips in film 2K resolution, RGB, 10 bit at 24p in real time. Data rates of 306 MB/sec (2.4 Gbit/sec) per data stream are achieved. Depending upon the configuration, up to three concurrent and independent data streams (up to 7.2 Gbit/sec) can be transferred. DVS-SAN, of course, works with products from other manufacturers, too.
The maximum storage capacity of a real-time DVS-SAN is many tens of terabytes. Such a system can store several complete feature films in film 2K resolution.
DVS-SAN is built with standard 19" racking. A minimum of 2 x 3U storage units is required. This corresponds to between 2.3 and 9.6 terabytes Ð more than six hours of 2K material. The capacity can be increased as required by adding storage units.
