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 System overviewDSA E2800 is based on a 4U dual controller unit with 60 internal 3.5", 7.2 K, NL-SAS (Serial Attached SCSI), enterprise HDDs (Nearline SAS) for high-capacity and extreme performance 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 fully redundant I/O paths, advanced protection features, and extensive diagnostic capabilities deliver high levels of availability, integrity, and security. Functions DSA 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. DSA E2800 60-bay dual controller configuration allows connecting up to two 60-bay expansion units (60 x HDDs per expansion shelf) connected to one dual controller base unit.It is a fully featured hardware RAID/DDP protected disk array which provides RAID-5 protection for capacity-oriented environments and RAID-6/DDP protection for availability-oriented environments. High reliability and availability DSA 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.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 Monitoring Full SNMP support with MIB-II and NetApp custom MIBs is provided. In case of component failures SNMP, e-mail alert notifications will be generated. Additionally, an event monitor for sending alert notifications to a central major event log is available. If the device is connected to the Internet/Intranet automatically generated AutoSupport messages can be sent, which helps to prevent issues before they occur.
