DSN-4000 Series
iSCSI SAN Array
Expansion Options
The DSN-4100 and DSN-4200 primary arrays each support 16 internal SAS/SATA hard
drives and with the addition of up to four DSN-4000 expansion arrays, can scale to a
total of 240TB
2
of raw storage capacity using 3TB
2
drives.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-4000 series combines both networking and storage
functions into a single specialized Application Specific Integrated Circuit (ASIC). This
SoC combines 10Gbps iSCSI, TCP & IP offload, 12 embedded processors and storage
virtualization firmware onto a single chip. The tight integration of these functions
eliminates interoperability, timing and support issues found in competitive products
that offer a “discrete implementation” wherein various components are selected
separately, then assembled.
RAID support
D-Link’s xStack Storage iSCSI SAN arrays support RAID level 0, 1, 1+0 and 5 configurations
(striped sets, mirrored sets, striped mirrored sets and parity sets) for data protection
and performance.
D-Link’s xStack Storage iSCSI SAN arrays support S.M.A.R.T. disk diagnostics, and non-
destructive data migration to prevent disk failure.
Embedded Centralized Storage Management
The embedded, user-friendly IP-SAN Device Manager (IDM) provides a comprehensive
console for system management. Boasting a rich set of management features, this suite
of utilities allows monitoring and control of the SAN array via the Storage Management
Initiative-Specification (SMI-S) command set. With a secure server, users can remotely
configure and monitor their SAN arrays over the Internet.
Advanced Management Features
The DSN-4000 series also provides an advanced set of features for efficient management
and optimal storage performance.
For the fastest RAID performance offered in the industry, D-Link’s adaptive cache
management provides write coalescing and multi-stream read-ahead on a volume
basis, optimizing cache utilization and performance in an application dependent
manner. Volatile cache data protection is afforded via an on-board battery supporting
cache memory for a minimum of 72 hours. A write-back or write-through cache
memory policy can be selected manually or automatically, depending on the status of
the battery’s charge.
The DSN-4000 series supports jumbo frames and VLAN tagging to segregate traffic
into isolated zones for secure access, improving network throughput and reducing
CPU overhead.
