About this Guide
USO RESTRITO
This user guide explains how to install, configure, and use the DataDirect Networks
StorageScaler 2460 enclosure.
This user guide assumes that you are familiar with Serial Attached SCSI (SAS), Serial ATA
(SATA) technology, computer hardware, data storage, and network administration
terminology and tasks.
Terminology Used in this Guide
Because this user guide provides information that can be used to manage one or more
SS2460 enclosures in a variety of configurations, the generic term “storage space” is used to
refer to the controller, disk drives, and enclosures being used together for data storage.
Many of the terms and concepts referred to in this user guide are known to computer users
by multiple names. In this user guide, this terminology is used:
• I/O Controller (also known as an I/O module, or controller)
• Disk drive (also known as hard disk, hard drive, or hard disk drive)
• HBA (also known as Host Bus Adapter or SAS/SATA Adapter)

Introduction
1.5 SAS I/O Controllers
The StorageScaler 2460 enclosure contains one or two SAS I/O controllers, which are
installed on the back of the enclosure. In the case of a single I/O controller system, the
controller is installed in Slot A (Figure 2).

Each controller has three SAS ports (Figure 4):
• Use the input ports (HOST 1 and HOST 2) to connect to the host systems.
• Use the expansion port (EXP) to connect to another StorageScaler 2460 enclosure. See
Section 1.8 for more information.
• When using the StorageScaler 2460 in a zoned configuration, the three SAS ports are
assigned drives specifically to separate host computers. Please refer to Appendix B for
supported zoned configurations.
Each controller also has eleven status LEDs, as described in Section 3.2, Monitoring the
Controllers.
To remove a controller from the enclosure, follow the instructions in Section 4.2.
1.6 Disk Drives and Drive Carriers
The StorageScaler 2460 enclosure supports up to 24 SAS or SATA disk drives. For disk drive
requirements, see Section 1.2. Disk drives are hot-swappable.
Each disk drive is mounted in a drive carrier (Figure 5) with a push-button lever for quick
installation and removal.

NOTE :
NOTE :
Each drive carrier has three LEDs, which indicate status as described in Section 3.3,
Monitoring the Disk Drives.
To maintain proper airflow and cooling inside the enclosure, drive slots (Figure 6) cannot be
left empty. Blank drive carriers are available to fill empty drive slots.
A disk drive must not be removed from its drive carrier. A disk drive removed
from its carrier is not covered by the hardware warranty.
All SATA disk drives installed in a dual-controller system require the use of a
2:1 SATA MUX assembly. Please contact your DataDirect Networks sales
representative to obtain the MUX cards.
1.7 Advanced Power and Cooling (APC) Units
Each SS2460 enclosure is equipped with two APC units (Figure 7) located on the back of the
enclosure.
The cooling fans in each APC unit run on separate circuits from the power supply.

1.8 Connection and Configuration Options
Introduction
This section describes the different connection options for your SS2460 enclosure.
NOTE :
Unless otherwise noted, the enclosures in all these configurations support
SAS or SATA disk drives, but not a combination of both.
1.8.1 Basic Configuration–Single Controller System
Connect your SS2460 enclosure to a SAS/SATA HBA or SAS/SATA RAID card in a single host
system (Figure 8).
As your storage space requirements change, you can upgrade and expand this basic
