Functions
The DSA‑N2B50 is the co-branded FAS Series FAS 2050
from NetApp which provides 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’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‑N2B50 allows
connecting up to six disk shelf expansion units to one
base unit. The base unit provides a maximum of 20 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‑N2B50 is a fully featured RAID protected disk
array which provides advanced RAID‑DP protection for
highest data availability. RAID‑DP (Double Parity) is a form
of RAID‑6 without any performance penalty.

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‑N2B50 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‑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.

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 DSA-N2B50 provides a maximum bandwidth of
300 Mbps with a maximum of 128 concurrent iSCSI
connections.
The net capacity available is shown in the following table.
