read-ahead on a volume basis, optimizing cache
utilization and performance in an application-dependant
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-3000 series supports jumbo frames and
VLAN tagging to segregate traffic into isolated zones
for secure access, improving network throughput
and reducing CPU overhead.
D-Link's volume virtualization technology utilizes
the concept of storage extents, which are the
fundamental building blocks used to enable features
such as RAID, online capacity expansion, volume
reconfiguration and migration. Each disk drive can
contain multiple and divergent RAID configurations

instead of requiring dedication to a single RAID set.
This technology allows for the support of mixed
disk drive capacities for volume creation. Volume
capacity expansion, volume configuration, and RAID
level migration are performed online with minimal
impact to users. Users can quickly deploy a SAN
using inexpensive SATA disk drives and simply add
more drives as needed.
Micro rebuilds provide protection against
unresponsive SATA commands by forcing a response
within a preset time limit.
An iSCSI SAN array can prove to be a valuable tool
to supplement a network storage foundation.
Whether providing a low-cost block-based solution
for data backup and recovery, replacement of Direct
Attached Storage (DAS) or providing a nearline
storage solution, the DSN-3000 series may provide
the performance and functionality needed.
