DSN-5000 series Hardware Reference Guide 1
Chapter 1 Introduction
The xStack Storage DSN-5000 series storage system is an intelligent, high-performance multiple
Gigabit Ethernet storage solution designed for businesses that want to improve the reliability,
availability, serviceability, and performance of their storage systems. It provides a range of
benefits and features from its ability to use familiar, proven, and widespread networking
technologies like IP and Ethernet for storage solutions.
The DSN-5000 series storage system is highly scalable. To add more storage capacity, simply
connect up to six additional expansion arrays to the DSN-5210-10 or DSN-5410-10 primary arrays
for up to 84 drives, or up to three additional expansion arrays to the DSN-5110-10 for up to 48
drives. This plug-and-play approach to storage expansion enables you to form a scalable
enterprise storage grid of many drives quickly and easily.
Based on an Internet Protocol-Storage Area Network (IP-SAN) architecture, the DSN-5000 series
primary array is built around an iSCSI RAID processor System-On-A-Chip and has the following
features:

Up to 12 internal Serial Attached SCSI (SAS) or Serial Advanced Technical Attachment (SATA)
drives per chassis, for a total of up to 84 drives per system (when additional DSN-5000-10
expansion arrays are connected) for the DSN-5210-10 and DSN-5410-10 arrays, or up to 48
drives per system for the DSN-5110-10 array.
The DSN-5110-10. DSN-5210-10, DSN-5410-10 and DSN-5000-10 units can all
support SATA hard drives when a single controller is used. However, the use
of SAS hard drives is recommended, and required for High Availability (HA)
operation.

Support for redundant controllers for High Availability (HA). For HA operation, a second
controller must be installed. The DSN-5110-10 will require the DSN-510 controller, the DSN-
5210-10 will require the DSN-520 controller and the DSN-5410-10 will require the DSN-540
controller. Please see previous note for SAS drive requirement.
 Up to 4GB of system memory (512MB standard)

Up to 4 GB of buffer (cache) memory:
1GB standard on the DSN-5110-10
2GB standard on the DSN-5210-10
2GB standard on the DSN-5410-10

iSCSI Ethernet Connectors:
Four 1-Gigabit RJ-45 connectors for the DSN-5110-10
Eight 1-Gigabit RJ-45 connectors for the DSN-5210-10
One 10-Gigabit Optical connector for the DSN-5410-10
 A 10/100/1000 Mbps Ethernet management port
 Two expansion connectors for attaching up to:
Three additional expansion arrays for the DSN-5110-10;
Six additional expansion arrays for the DSN-5210-10;
Six additional expansion arrays for the DSN-5410-10
