The DSDA iSCSI series represent the second generation of
Bosch Digital Video Disk Arrays and are designed for the
security industries most demanding digital video storage
applications to manage the relentlessly growing digital
video data.
Functions
The DSA‑N2B20 is the co-branded FAS Series FAS 2020
from NetApp which provides a scale-out network storage
solution that provides security, high “in-the-box”
scalability, peace-of-mind data protection, and simplified
management of all your video data. NetApp’s FAS Series
are based on a 15‑year enterprise proven and well tested
OS—Data ONTAP. NetApp pioneered the iSCSI protocol
years ago and remains the market leader.
Designed as a scale-out system, the DSA‑N2B20 allows
connecting up to four disk shelf expansion units to one
base unit. The base unit provides a maximum of 12 x 1 TB
SATA‑II hard disk drives and each disk shelf expansion
unit will provide a maximum of 14 x 1 TB hard disk drives.
The DSA‑N2B20 is a fully featured RAID protected disk
array which provides RAID‑4 protection for capacity-
oriented environments and RAID‑DP protection for
availability oriented environments. RAID‑DP (Double
Parity) is a form of RAID‑6 without any performance
penalty. RAID-DP is strongly recommended if the system
will be used with disk shelf expansion units.
High Reliability and Availability
With redundant hot-swap power and cooling, dual Gigabit
Ethernet ports, NVRAM, and protection from double-disk
failure and single bit errors during RAID rebuilds with
RAID‑DP, the DSA‑N2B20 keeps your data safe and
available.
Monitoring
Full SNMP support with agents compatible with SNMP
version 1 as well as MIB‑II and NetApp custom MIBs
supported. In case of component failures SNMP, e-mails
(Autosupport Mails) or HTTP (HTTPS) messages will be
generated.
Features
The intelligent combination of battery backed up
nonvolatile RAM (NVRAM), the NetApp RAID‑DP
technology and the Write Anywhere File Layout (WAFL) all
contribute to data reliability and recoverability and
provide superior system performance.
The RAID‑4 or the RAID‑DP protection allows for capacity
expansion on the fly, with no RAID rebuilt or interruption
to users. This is getting more and more important as HDD
capacities are getting bigger and bigger.
All Bosch NetApp systems come with a 3 years Next
Business Day Parts Delivery warranty and with a 3 years
software warranty.
Installation/Configuration Notes
Central management is provided by a Web GUI
administration tool. 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 either by
telnet, ssh or rsh. The co-branded Bosch NetApp
DSA‑N2B20 comes with the Data ONTAP 7.3.1P1D9 OS
version.
The DSA‑N2B20 provides a maximum bandwidth of
250 Mbps with a maximum of 128 concurrent iSCSI
connections.
