Area Network (SAN) Arrays
(DSN-3200 & DSN-3400) provide a reliable network data
storage solution for customers in entry-level and SMB
segments. Utilizing a 10Gbit iSCSI System-on-a-Chip (SoC)
solution that can handle over 80,000 I/Os per second and
capable of supporting 30TB raw capacity using 2TB hard
drives (and even higher capacity hard drives as they are
introduced), the DSN-3000 Arrays can easily be implemented
as nearline storage to supplement your primary IP network
storage solution or used as a basic backup and recovery
device. This evolutionary advancement in performance
is a testament to the tightly integrated xStack Storage
architecture and is a sharp contrast to the discrete
implementation of competing products.
iSCSI for IP Networks
SAN has been traditionally reserved for Fibre Channel
networks until the recent introduction of iSCSI extended
this powerful yet simple centralized backend (behind
server-based) storage system to IP networks. By utilizing
existing Ethernet technology, the cost associated with
separate host bus adapters and the per-Gigabyte cost for
storage is signifi cantly reduced. IP SANs based on iSCSI
technology can leverage existing and familiar Ethernet
standards to provide speeds of up to 1160 MB/s bandwidth
(DSN-3400).
A Choice of Host Interfaces – 1GbE or 10GbE
The DSN-3200 implements eight 1GbE ports and supports
IEEE 802.3ad Link Aggregation Groups (LAG) for full offl oad
capability so that all eight ports can be grouped together,
totaling up to 850MB/s bandwidth, for increased throughput
and redundancy.
The DSN-3400 implements the industry’s fi rst built-in, fully
integrated 10GbE interface in the XStack Storage cost
effective solution. Providing up to 1160MB/s bandwidth,
it offers a high performance alternative to 4Gbps Fibre
Channel.
System-on-a-Chip (SoC) Implementation
By utilizing a SoC design, the DSN-3000 Series SAN Arrays
combine both networking and storage functions into a single
specialized Application Specifi c Integrated Circuit (ASIC). The
SoC solution combines 10Gbps iSCSI, TCP & IP offl oad, embedded
processors, and a storage virtualization fi rmware stack onto a
single chip. The tight integration of these functions eliminates
interoperability, timing, and support issues found in competitive
products that offer “discrete implementation” wherein a chassis,
a main motherboard, a RAID storage controller, iSCSI software
or controller, network interface cards, and operating system
software are picked separately and then assembled. The
DSN-3000 line outperforms these discrete implementations
and does so at a lower price point, while delivering mission
critical data quickly with state-of-the-art reliability.
RAID for Effi ciency
The DSN-3000 Series SAN Array platform features 15 hot
swappable Serial ATA (SATA) disk drive bays supporting 30TB
raw capacity using 2TB hard drives (and even higher capacity
hard drives as they are introduced) in RAID level 0, 1, 1+0
and 5 confi gurations. You can quickly deploy a SAN using
inexpensive SATA disk drives, and depending on your growing
storage needs, you can simply add more drives as you go.
Embedded Centralized Storage Management
The embedded, user-friendly IP-SAN Device Manager (IDM)
provides comprehensive network storage management. Boasting
a rich set of management features, this suite of utilities allows
monitoring and control of your SAN via the SMI-S (Storage
Management Initiative) command set. Combined with an
embedded secure server, users will be able to remotely confi gure
and monitor their SAN storage subsystems.
