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 overview
DSA 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.
uScale-up network storage solution: controller unit with 60 internal HDDs expandable via state-of-the- art SAS interface-connected expansion units
uConfigurable hardware-based RAID/DDP protection (RAID 5, RAID 6 or DDP) for highest system performance
uRedundant hot-swappable power supplies and cooling fans
uTwo 10 Gigabit Ethernet ports for highest speed iSCSI connectivity
uFully modular design for ease of service and protected by NetApp services, including a 3 years next business day on-site support
The DSA E2800 disk shelf option with a high density 60-bay expansion unit with 60 x 3.5”, 7.2 K, NL-SAS, enterprise HDD (4U) enables custom configurations that can be optimized for any standard midto 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.
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. NetApp pioneered the iSCSI protocol years ago and offers with the new E2800 product line a high-end product for the video surveillance market.
2 | DSA E-Series (E2800 60-bay)
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 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 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.
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
Monitoring
Full SNMP support with MIB II and NetApp custom MIBs supported. 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. AutoSupport enhances customer service, speeds problem resolution, and helps prevent issues. It automatically sends alerts based on either eventbased or time-based (weekly, daily, other) criteria to provide faster and better customer service, keeping your systems up and running longer.
Management
NetApp SANtricity storage management software combines robustness and ease of use. Full-time storage administrators appreciate the extensive configuration flexibility which allows optimal performance tuning and complete control over data placement. Part-time system administrators love the intuitive interface and wizards designed to simplify their tasks. With its dynamic capabilities, SANtricity software supports on-the-fly expansion, reconfiguration, and maintenance without interrupting storage system I/O.

Installation/configuration notes
Bosch provides the necessary software tools for an initial setup of the storage in a video surveillance environment. In addition, the system provides web based configuration and a powerful Command Line Interface (CLI) which is fully remote accessible by SSH (Secure Shell).
DSA E Series offers per controller a serial console connector and 2 dedicated Ethernet management ports for management access, 2 x 10 Gigabit Ethernet iSCSI host ports, and 2 additional optical iSCSI ports. Each port must be configured with a separate IP address; the 4 iSCSI ports are separated access paths to the storage system and represent an individual iSCSI target each.
In dual controller systems the iSCSI ports with the same number are tied together for redundancy purpose, while one of the ports is a fall-back path for an iSCSI port on the other controller.
