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 one or two additional expansion arrays to the xStack Storage primary array. This
plug-and-play approach to storage expansion enables you to form a scalable enterprise
storage grid of up to 36 drives and up to 36 terabytes using 1TB drives quickly and easily
(larger drives supported as they become available).
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) per chassis and up to 36 drives per system.
The DSN-5210, DSN-5410 and DSN-5000 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-5210 will require the DSN-520 controller and the
DSN-5410 will require the DSN-540 controller. Please see previous note for SAS drive
requirement.
512MB of system memory
2 GB of buffer (cache) memory
Eight GbE iSCSI connectors (DSN-5210) or one 10 Gigabit Ethernet iSCSI connector (DSN-
5410)
A 10/100/1000 Mbps Ethernet management port
Two expansion connectors for attaching up to two additional expansion arrays
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.
