u Scale-up network storage solution: controller unit
with 12 internal HDDs with up to 192 HDDs via
state-of-the-art SAS interface-connected expansion
units
DSA E2700 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 E2700 is the answer to it.
System overview
DSA E2700 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 Simplex
Controller configuration and as a Dual Simplex
Controller configuration for high-capacity and extreme
performance requirements.
u Configurable hardware-based RAID protection
(RAID‑5 or RAID‑6) for highest system performance
u Redundant hot-swappable power supplies and
cooling fans
u Two 10 Gigabit Ethernet ports for highest speed
iSCSI connectivity
u Fully modular design for ease of service and
protected by NetApp services, including a 3 years
next business day on-site support
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 E2700 disk shelf option with a standard 12bay expansion unit with 12 x 3.5”, 7.2 K, NL-SAS,
enterprise HDD (2U) and a high-density 60-bay
expansion unit with 60 x 3.5”, 7.2 K, NL-SAS,
enterprise HDD (4U) enable custom configurations
that can be optimized for any standard mid- to
enterprise-environments.
And the DSA E2700 fully redundant I/O paths,
advanced protection features, and extensive
diagnostic capabilities deliver high levels of
availability, integrity, and security.
Functions
DSA E2700 is the co-branded E2700 series from
NetApp. It is a scale-up network storage solution that
provides security, highest “in-the-box” scalability,
2 | DSA E-Series 4TB (E2700)
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
E2700 product line a high-end product for the video
surveillance market.
DSA E2700 in Simplex/Dual Simplex Controller
configuration allows connecting up to seven 12-bay
expansion units (12 x HDDs per expansion shelf) to
one single/dual controller base unit.
Note: This is only valid for 12-bay expansion units with
two ESM modules.
The Dual Simplex Controller configuration allows up to
three 60-bay expansion units (60 x HDDs per
expansion shelf) connected to one dual controller
base unit. Connecting the 60-bay expansion unit to a
single controller unit is not supported.
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 E2700 keeps your data safe and available with
redundant hot-swappable power supplies 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 E2700 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 DSA E2700 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 event-based
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. The software is available as 32‑bit
and 64‑bit Microsoft OS installation package (available
on the Bosch product catalogue).

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.
