DSA e ￣ series represents Bosch's next generation of iSCSI

 digital video disk array. The top platform specially designed for the security field can meet the most demanding digital video storage application requirements in the field, and can manage the increasing number of digital video data. As high-definition IP cameras and encoders enter the monitoring market, the main challenge for this application is the growing demand for high bandwidth and low complexity of the storage infrastructure. The new DSA e ￣ series solves this problem. System overview DSA e ￣ series is based on a 2U controller unit with 12 internal SAS (Serial Attached SCSI) enterprise class hard disks (nearline SAS) of 3.5 "size and rotating speed of 7.2k. For large capacity, extreme performance requirements, the controller unit can be used as standard simplex controller configuration and dual simplex controller configuration. The storage system is a high-performance solution with super flexible design, which is very suitable for a wide range of video monitoring requirements. Its balanced performance is designed to support high bandwidth and I / O intensive workloads. The disk shelf option of DSA e ￣ series is equipped with a standard 2U expansion unit with 12 SAS Enterprise hard disks of 3.5-inch size and 7.2k speed, and a high-density 4U expansion unit with 60 SAS Enterprise hard disks of 3.5-inch size and 7.2k speed, which allow custom configuration to be optimized for any environment. Furthermore, the fully redundant I / O paths, advanced protection features and extensive diagnostic capabilities of DSA e ￣ series bring high levels of availability, integrity and security. Basic function DSA e ￣ series is a co brand e2600 series launched by NetApp. It's a scalable network storage solution that provides superior security, highly "out of the box" scalability, trustworthy data protection, and simplified management for all your video data. NetApp pioneered the development of the iSCSI protocol a few years ago and created the next-generation e2600 family of high-end products for the physical security market. The DSA e ￣ series for simplex controller configuration allows up to seven disk shelf expansion units (12 hard disks per expansion shelf) to be connected to a simplex controller base unit. In a dual simplex controller configuration, you can connect up to three high-density shelf expansion units (60 hard disks on each expansion shelf) to a dual controller base unit. It is a fully functional raid protected disk array, which can provide raid ￣ 5 Protection for environments requiring high capacity and raid ￣ 6 protection for environments requiring high availability. Raid protection is based on hardware raid implementation to achieve maximum system performance. If the system will work with multiple shelf expansion units, RAID-6 is highly recommended. Superior reliability and availability DSA e ￣ series maintains the security and availability of your data through redundant hot swap power supplies and fans, and prevents double disk failures and single bit errors during raid reconstruction with high-performance raid ￣ 6. With more than 20 years of storage development experience, DSA e ￣ series is based on a field proven design designed to provide high reliability and availability. Its redundant components, automatic path fail over, and online management keep your organization up and running 24 hours a year.
