Understanding RAID
RAID is an acronym for Redundant Array of Independent Disks. A RAID system consists of an
array of multiple independent hard disk drives that provide high performance and fault tolerance.
The RAID controller implements several levels of the Berkeley RAID technology. An
appropriate RAID level is selected when the volume sets are defined or created. This decision is
based on disk capacity, data availability (fault tolerance or redundancy) and disk performance.
The RAID controller makes the RAID implementation and the disks physical configuration
transparent to the host operating system. This means that the host operating system drivers and
software utilities are not affected, regardless of the RAID level selected. Correct installation of
the disk array and the controller requires a proper understanding
of RAID technology and the concepts.
RAID 0
RAID 0, also referred to as striping, writes stripes of data across multiple disk drives. RAID 0
does not provide any data redundancy, but does offer the best high-speed data throughput. RAID
0 breaks up data into smaller blocks and then writes a block to each drive in the array. Disk
striping enhances performance because multiple drives are accessed simultaneously; but the
reliability of RAID Level 0 is less than any of its member disk drives due to its lack of
redundancy.
RAID 1
RAID 1 also known as “disk mirroring”, means that data written to one disk drive is
simultaneously written to a second disk drive. Read performance may be enhanced if the array
controller can simultaneously access both members of a mirrored pair. During writes, there will
however, be a minor performance penalty when compared to writing to a single disk as two
writes must occur (one to each disk drive). If one drive fails, all data (and software applications)
is preserved on the other drive. RAID 1 offers extremely high data reliability, but at the cost of
doubling the required data storage capacity.
SAFEStor User Guide
Page 3
RAID 0+1
RAID 0+1 is a combination of RAID 0 and RAID 1, combining stripping with disk mirroring.
RAID Level 0+1 combines the fast performance of Level 0 with the data redundancy of Level 1.
In this configuration, data is distributed across several disk drives, similar to Level 0, which are
then duplicated to another set of drives for data protection.
RAID 3
RAID 3 provides disk striping and data redundancy though the use of a dedicated parity drive.
RAID 3 breaks up data into smaller blocks, calculates parity by performing an exclusive-or
operation on the blocks, and then writes the blocks to all but one drive in the array. The parity
data created during the exclusive-or operation is then written to the remaining drive in the array.
If a drive fails, data on the failed drive can be recovered using the information on the parity
drive. RAID 3 is the best choice for applications that require very fast data transfer rates or large
data transfers.
SAFEStor User Guide
Page 4
RAID 5
In RAID 5, the parity information is written to all of the drives in the array rather than being
concentrated on a dedicated parity disk. If one drive in the array fails, the parity information can
be used to reconstruct the missing data from that drive. All drives in the array can read and write
data at the same time, greatly increasing the performance of the RAID system.
RAID 6
RAID 6 extends a RAID 5 array by using dual distributed parity. Data and parity is striped at
block level across all member drives, just like in RAID 5. However, two sets of parity are
calculated and written across all the drives. When a disk fails, the data is recovered from the
remaining disks. RAID 6 provides the ultimate level of fault tolerance and can sustain two
simultaneous drive failures without downtime or data loss.
RAID 6 offers a perfect solution for mission-critical data.

Chapter 2 – Initial Setup and Installation
This Chapter describes the installation and set up of the SAFEStor storage enclosure. Important
safety details are described along with the environmental and electrical precautions that must be
taken. The location of components within the enclosure is also shown.
Please read this chapter carefully before attempting to install or operate the unit.
Safety Statements
The following safety requirements must be understood before you install or operate the
SAFEStor Subsystem.
Warning: Disconnect all power supply inlets before opening the XRX series storage
enclosure for maintenance.
Caution: Do not place the enclosure on an uneven or unstable work surface.
Caution: Do not place or drop objects onto the enclosure and do not force any foreign
objects into it.
Caution: Do not expose the SAFEStor series storage enclosure to extreme
temperatures (below 5 ºC or above 30 ºC) or to direct sunlight.
Caution: Allow disk drives and power supplies to reach ambient room temperature
before applying power to the enclosure.
Unpacking
When you receive the unit, visually inspect the exterior of thepackaging for any signs of damage.
If any damage is found, you should inform your distributor. Once the packaging is opened, the
contents should be checked against the enclosed Packing List. If any items are missing or
damaged you should contact your distributor immediately.
CAUTION: Allow disk drives and power supplies to reach room ambient temperature
before applying power to the enclosure.
Environmental Considerations
This section outlines the environmental factors that must be considered when choosing a suitable
location to install the storage enclosure.
Temperature
The operating temperature of the storage enclosure is between 5oC and 30oC. However, it is not
recommended that the enclosure be continuously run at these extreme temperatures.
Consideration should therefore be give to ensure that the room ambient temperatureis compatible
with these specifications.
SAFEStor User Guide
Page 6
Air Flow
To ensure that internal heat build up is properly dissipated into the surrounding environment, the
enclosure should be positioned such that no air vents are blocked or obstructed in any way.
Failure to ensure this can lead to heat build up in the enclosure and damage to the components.
Electrical Considerations
You must ensure that the required current does not exceed the rating of the power source. This
includes cabling, power distribution units, filters and any other devices through which the main
current flows. Surge currents must be catered for. Disk drives may consume twice the amount of
current at start-up time as they do during steady state operation.
Installing a Disk Drive
Warning: Disconnect the power supply inlets before opening the storage enclosure for
maintenance.
Caution: Do not place or drop objects onto the enclosure and do not force any foreign
objects into it.
Caution: Allow disk drives and power supplies to reach ambient room temperature
before applying power to the enclosure.
To install a Disk Drive in the storage enclosure, follow the procedure below:
1. Orient the Disk Drive carrier so that the LED indicator is at the bottom.
2. With the locking lever fully open, gentlyslide the Disk Drive carrier into the desired slot
on the front of the enclosure.
3. When the Disk Drive carrier is in all the way, slowly close the locking lever until it
‘clicks’ into place.
Locating Components
The SAFEStor family uses dual external 180W power supplies which plug into the rear of the
unit. The following pictures show where the components are located within the enclosures.

Chapter 3 – Initial Configuration
This Chapter describes how to install the hardware and how to connect to and access the RAID
Controller.
Attaching the SCSI Cables to XRX-2PSQX-651-U4
There are two SCSI ports on the rear of the XRX-2PSQX-651-U4 enclosure. Attach the SCSI
cable (or 2 cables if required) to the SCSI ports.
NOTE: If only one SCSI cable is connected to the enclosure, you must install a SCSI
terminator.
Attaching the Fibre Channel Cables to
XRX-2PSQX-652-FC
There are two Fibre channel SFP Ports on the rear of the XRX-2PSQX-652-FC enclosure at the
rear of the unit. Insert the SFP adapters and then attach the FC cabling to these ports.
Accessing the RAID Controller
Following the hardware installation, the RAID subsystem disk drives must be configured and the
volume sets initialized, before they are ready to use. This is carried out using one of the
following methods:
•
VT100 terminal connected through the RAID subsystem serial port.
•
Firmware-embedded TCP/IP & web browser-based RAID manager via the 10/100
Ethernet LAN port.
The embedded RAID manager provides complete control and management of the RAID
subsystem, eliminating the need for additional hardware or software.
NOTE: The RAID subsystem must only be accessed through one method at a time.
VT100 terminal (via serial port)
The serial port located at the rear of the unit can be used in VT100 mode. The interface cable
provided connects the RS232 port to a PC. The embedded RAID management interface can
access the array through the RS-232 port. You can attach a VT-100 compatible terminal or a PC
running a VT-100 terminal emulation program to the serial port to access the text-based Set-up
Menu.
RAID subsystem RS-232C Port Configuration
To ensure proper communications between the RAID subsystem and VT-100 Terminal
Emulation program, use the following communication settings:
SAFEStor User Guide
Page 12
Connection Null-modem cable
Baud Rate 115,200
Data bits 8
Stop 1
Flow Control None
By connecting a VT100 terminal, or a PC operating in an equivalent terminal emulation mode,
all RAID subsystem monitoring, configuration and administration functions can be carried out.
There is a wide variety of Terminal Emulation packages available, such as Hyperterm. Open the
Terminal Emulator of your choice and configure the Settings of the Terminal port as shown in
the Terminal Requirements table above.
When the VT100 Terminal set-up is complete, you can press the " X " key (on your Terminal) to
link the RAID subsystem and Terminal together. The disk array Monitor Utility screen is
displayed on your VT100 Terminal.
Please refer to Chapter 5 to continue with the configuration of the unit using the VT-100
terminal software.
Web browser -based RAID manager
Firmware-embedded web browser RAID manager is a HTTP–based application, which utilizes
the browser installed on your operating system. You can use the Ethernet LAN port (see Chapter
2 for location of components) to configure the subsystem without any additional software or
drivers.
You can manage the RAID subsystem remotely without adding any user specific software
(platform independent) via standard web browsers connected directly to the 10/100 Ethernet
RJ45 LAN port.
To configure the RAID subsystem on a local or remote machine, you need to know its IP
Address. The IP address is detailed on the Product Documentation and Quality Sheet provided
with the unit.
To launch the TCP/IP & Web Browser-based RAID manager, enter:
http://[IP Address]
NOTE: You must be logged-in as administrator with local admin rights on the workstation to
remotely configure RAID subsystem. The user name and password are case sensitive. The
default values are:
User Name: “admin”
Password: “0000”
SAFEStor User Guide
