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.
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 availability-
oriented 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.
