Chapter 1 Overview
1.1 Features
D-Link DSN-6000 series IP SAN storage provides non-stop service with a high degree of
fault tolerance by using D-Link RAID technology and advanced array management
features.
DSN-6110/6120 IP SAN storage connects to the host system by iSCSI interface. It can
be configured to numerous RAID level. The IP SAN storage provides reliable data
protection for servers by using RAID 6. The RAID 6 allows two HDD failures without any
impact on the existing data. Data can be recovered from the existing data and parity
drives. (Data can be recovered from the rest drives.)

Snapshot-on-the-box is a fully usable copy of a defined collection of data that contains
an image of the data as it appeared at the point in time, which means a point-in-time data
replication. It provides consistent and instant copies of data volumes without any system
downtime. Snapshot-on-the-box can keep up to 32 snapshots for one logical volume.
Rollback feature is provided for restoring the previous-snapshot data easily while
continuously using the volume for further data access. The data access which includes
read / write is working as usual without any impact to end users. The "on-the-box" implies
that it does not require any proprietary agents installed at host side. The snapshot is taken
at target side. It will not consume any host CPU time thus the server is dedicated to the
specific or other application. The snapshot copies can be taken manually or by schedule
every hour or every day, depends on the modification.
D-Link IP SAN storage is the most cost-effective disk array system with completely
integrated high-performance and data-protection capabilities which meet or exceed the
highest industry standards, and the best data solution for small / medium business
(SMB) and enterprise users.
