1.1 Models
The xStack Storage DSN-5000 series storage array is available in various models. The models
differ according to the speed and host network interface. Table 1-1 lists the xStack Storage
DSN-5000 series array models.

Model Description
DSN-5210 (single controller) System
DSN-520 (additional controller)
Number of host network connections: Eight RJ-45 ports
Speed: 1 Gbps
Maximum number of internal SAS drives: 12
System memory: 512 MB
Buffer (cache) memory: 2 GB
Single or Dual controllers are allowed
A DSN-520 controller is installed in the empty bay of the DSN-5210 for High Availability
DSN-5410 (single controller) System
DSN-540 (additional controller)
Number of host network connections: One optical XFP transceiver host network connection
- XFP transceiver sold separately
Speed: 10 Gbps
Maximum number of internal SAS drives: 12
System memory: 512 MB
Buffer (cache) memory: 2 GB
Single or Dual controllers are allowed
A DSN-540 controller is installed in the empty bay of the DSN-5410 for High Availability
- XFP transceiver sold separately
DSN-5000 (single I/O module) Expansion
DSN-500 (additional I/O module)
This is an expansion array with a single I/O module that is used with a DSN-5210 or DSN-5410
Maximum number of SAS drives: 12
Each I/O module provides two SAS expansion ports
Single or Dual I/O modules are allowed
A DSN-500 I/O module is installed in the empty bay of the DSN-5000 for High Availability
High Availability (HA) Note: A system using a single controller (DSN-5210 or
DSN-5410) and its expansion array(s) may use SAS or SATA drives. A system
using dual controllers for High Availability operation (DSN-520 for the 5210
or DSN-540 for the 5410) 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.
