DSA E2800 represents the next generation of DSA E-Series, the iSCSI-based digital video disk arrays by Bosch. They are state-of-the-art platforms designed for the security industries most demanding digital video storage applications to manage relentlessly growing digital video data. Since HD and recently UHD (4K) IP cameras and encoders have entered the surveillance market, the ever growing need for high bandwidth and low complexity of the storage infrastructure are the main challenges. The next generation DSA E2800 disk arrays are the answer to it.System overviewDSA E2800 is based on one 2U controller unit with 12 internal 3.5", 7.2 K, NL-SAS (Serial Attached SCSI), enterprise HDDs (Nearline SAS).The controller unit is available as a standard single controller configuration and as a dual controller configuration for high availability requirements.This storage system is a high-performance solution designed with robust flexibility that makes it a great fit for wide-ranging video surveillance requirements. Its balanced performance is designed for supporting high bandwidth and I/O intensive workloads.The DSA E2800 disk shelf option with a standard 12- bay expansion unit with 12 x 3.5", 7.2 K, NL-SAS, enterprise HDD (2U) enables custom configurations that can be optimized for any standard mid- to enterprise-environments.And the DSA E2800 fully redundant I/O paths, advanced protection features, and extensive diagnostic capabilities deliver high levels of availability, integrity, and security.FunctionsDSA E2800 is the co-branded E2800 series from NetApp. It is a scale-up network storage solution that provides security, highest "in-the-box" scalability, peace-of-mind data protection, and simplified management of all your video data. NetApp pioneered the iSCSI protocol years ago and offers with the new E2800 product line a high-end product for the video surveillance market.DSA E2800 in single or dual controller configuration allows connecting up to seven 12-bay expansion units (12 x HDDs per expansion shelf) to one single or dual controller base unit.It is a fully featured RAID/DDP protected disk array which provides RAID-5 protection for capacity-oriented environments and RAID-6/DDP protection for availability-oriented environments. The RAID and DDP (Dynamic Disk Pools) protection is based on a hardware implementation which ensures highest system performance.High reliability and availabilityDSA E2800 keeps your data safe and available with redundant hot-swappable power supplies and fans, and protects from double-disk failure and single bit errors during rebuilds with high performance RAID-6 or DDP.With over 20 years of storage development experience, DSA E-Series is based on a field-proven design architected to provide high reliability and availability. Its redundant components, automated path failover, and online administration keep organizations productive 24 x 7 x 365.Further high-availability features include: Automatic drive failover and detection and rebuild if using global hot spare drives Data cache with battery backup and de-stage to flash SANtricity proactive drive health monitoring identifies problem drives before they create issues
