DSA E Series represents the next generation of iSCSI 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 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 new
DSA E Series is the answer to it.
System overview
DSA E Series is based on one 2U controller unit with 12 internal 3.5”, 7.2 K, SAS (Serial Attached SCSI), enterprise HDDs (Nearline SAS).
The controller unit is available as a standard Simplex Controller configuration and as a Dual Simplex Controller configuration 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-out network storage solution: controller unit with 12 internal HDDs with up to 192 HDDs via state-of-the-art SAS interface-connected expansion units
uConfigurable hardware-based RAID protection (RAID 5 or RAID 6) 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
The DSA E Series’ disk shelf option with a standard 2U expansion unit with 12 x 3.5”, 7.2 K, SAS, enterprise HDD and a high-density 4U expansion unit with 60 x 3.5”, 7.2 K, SAS, enterprise HDD enable custom configurations that can be optimized for any environment.
And the DSA E Series’ fully redundant I/O paths, advanced protection features, and extensive diagnostic capabilities deliver high levels of availability, integrity, and security.
Functions
DSA E Series is the co-branded E2600 series from NetApp. It is a scale-out 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 E2600 product line a high-end product for the physical security market.
DSA E Series in Simplex Controller configuration allows connecting up to seven disk shelf expansion units (12 x HDDs per expansion shelf) to one Single Controller base unit.

In Dual Simplex Controller configuration up to three high-density shelf expansion units (60 x HDDs per expansion shelf) to one Dual Controller base unit may be connected. But note: The capacity must be equally assigned to each controller of the Dual Controller system.
It is a fully featured RAID protected disk array which provides RAID 5 protection for capacity-oriented environments and RAID 6 protection for availabilityoriented environments. The RAID protection is based on a hardware RAID implementation for highest system performance. RAID 6 is highly recommended if the system will be used with a larger number of disk shelf expansion units.
High reliability and availability
DSA E Series keeps your data safe and available with redundant hot-swappable power and fans, and protection from double-disk failure and single bit errors during RAID rebuilds with high performance RAID 6.
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 using global hot spare drives
•Mirrored data cache with battery backup and destage 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.
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. SANtricity software is available as 32 bit and 64 bit Microsoft OS installation package.

Installation/configuration notes
Installable on 32-bit and 64-bit Windows Clients, SANtricity storage management software provides easy central management of all DSA E Series arrays available within one network. There is no additional software necessary to be installed on peripheral devices. In addition, the system provides 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 two dedicated Ethernet management ports for management access and 2 x 10 Gigabit Ethernet iSCSI host ports. Each port must be configured with a separate IP address; the two iSCSI host ports are separated access paths to the storage system and represent an individual iSCSI target each.
