JBOD storage extension, up to 44× 3.5“ SATA/SAS hard disk drives, 1× cable SFF-8088, 2× power supply units, without HDDs, rack-mount housing 
The JBOD storage extension must be installed in a robust 4RU rack-mount housing with black front panel and have two high-performance and redundant power supply modules. The best-tuned components must be designed for optimum operation in conjunction with the manufacturer's recording systems. An external SFF-8088 connection cable with 12 Gbps must be included in the scope of delivery.
The JBOD storage extension must have a total of 44 removable frames for 3.5" hard disks drives on the front and rear side. Depending on the equipment of the recording system used, the storage expansion must be able to be equipped with SATA or SAS hard disks.
The JBOD storage extension must build its own RAID system that is controlled by the RAID controller of the recording system. In full configuration, it must be possible to realize a storage capacity of at least 800 TB in total with two RAID 6 volumes.
If necessary, the available storage capacity must be doubled by connecting another memory expansion of the same design. The manufacturer must recommend hard drives that are approved for the workstation after long-term tests.
The storage extension must be designed with a robust 4RU rack-mount housing for commercial and industrial indoor use with 24/7/365 continuous operation.
