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

2 Chapter 1 Introduction
 A 115.2 Kbps RS-232-C stereo mini-jack diagnostic port for troubleshooting purposes
Complete configuration and management of the storage system are available through the
intuitive, graphical-based xStack Storage Management Center software.

High Availability (HA) Note: A system using a single controller (DSN-5110-10,
DSN-5210-10 or DSN-5410-10) and its expansion array(s) may use SAS or SATA
drives. A system using dual controllers for High Availability operation (DSN-
510 for the 5110-10, DSN-520 for the 5210-10 or DSN-540 for the 5410-10)
requires SAS drives be used in both the primary array and any expansion
array(s).
If you anticipate upgrading to HA with the addition of a second controller,
then it is recommended you install SAS drives.

1.3 System Overview
Figure 1-1 shows a typical DSN-5000 series storage system (primary array DSN-5110-10, DSN-5210-10
or DSN-5410-10) configuration in a Storage Area Network (SAN). The SAN shown is an Ethernet
network used solely for exchanging data between the customer's host servers and the DSN-5000
series storage system. The Ethernet bandwidth used by the servers exchanging data with the DSN-
5000 series storage system can be very high. Using a separate Ethernet network to act as a SAN
keeps that data from interfering with the customer's existing LAN and improves security.
Figure 1-1. Example of aDSN-5000 series Storage System Configuration
When equipped with dual controllers, the DSN-5000 series primary array provides High
Availability (HA) with automatic failover to the redundant controller. When a failure occurs on
the primary controller, the Management Port and all of the iSCSI data ports will be automatically
redirected to the equivalent ports on the redundant controller, without any interruption to your
host server applications. To accomplish the redirection of network traffic on those ports, a
network switch must be used between the host server(s) and both of the controllers found in the
DSN-5000 series primary array prior to system startup to allow the automatic re-direction of the
network connections to the redundant controller when a failure occurs on the primary controller.
For example, the Management Port network connection on both controllers must be connected to
the same network switch. Similarly, Data Port 0 on both controllers must also be connected to
the same network switch, and so on.
A Field Upgrade Kit is available to add a redundant controller (DSN-510 for the 5110-10, DSN-520
for the 5210-10 or DSN-540 for the 5410-10) to any existing single-controller system. Similarly, a
Field Upgrade Kit is available to add a second I/O Module to the DSN-5000-10 expansion array
(The expansion array with a single I/O module is the DSN-5000-10. An additional I/O module for
the DSN-5000-10 is the DSN-500), which is required when the DSN-5110-10, 5210-10 or 5410-10
system is equipped with dual controllers.
To clarify: DSN-5110-10, DSN-5210-10 or DSN-5410-10 systems all have a single controller. For
additional storage array expansion, each would require a DSN-5000-10 expansion array which
itself has a single I/O module. A single external SAS to mini-SAS cable (provided with the DSN-
5000-10) will then connect the controller in the DSN-5110-10, DSN-5210-10 or DSN-5410-10 to the
I/O module in the DSN-5000-10.

DSN-5000 seriesHardwareReference Guide 7
A DSN-5110-10 with dual controllers (an additional controller DSN-510 is inserted in the second bay),
a DSN-5210-10 with dual controllers (an additional controller DSN-520 is inserted in the second bay)
or a DSN-5410-10 with dual controllers (an additional controller DSN-540 is inserted in the second
bay) will require a DSN-5000-10 expansion array with two I/O modules (an additional I/O module
DSN-500 is inserted in the second bay of the DSN-5000-10). An additional SAS to mini-SAS cable
(provided with the DSN-500) will connect the second controller in the DSN-5110-10, DSN-5210-10 or
DSN-5410-10 to the second I/O module (DSN-500) installed in the DSN-5000-10 expansion array. You
will now have dual redundancy between the DSN-5110-10, DSN-5210-10 or DSN-5410-10 and the DSN-
5000-10 expansion array.
