Terminology

RAID

Redundant Array of Independent Disks. There are different RAID levels with

different degrees of data protection, data availability, and performance.

JBOD

“Just a Bunch Of Disks”. JBOD needs at least one hard drive.

Physical Disk. Belongs to the member disk of one specific RAID group.

RAID Group. A collection of removable media. One RG consists of a set of

VDs and owns one RAID level attribute.

Virtual Disk. Each RG could be divided into several VDs. The VDs from one

RG have the same RAID level, but may have different volume capacity.

LUN

Logical Unit Number. A unique identifier for a SCSI device which enables

computers to differentiate among separate SCSI devices.

GUI

Graphical User Interface.

RAID cell

The number of subgroups of PDs in an RG.

Dedicated Spare disk. A spare disk dedicated to one specific RG and is used

when another disk in the RG fails.

Global Spare disk. A spare disk that is shared among all RGs and is used

when another disk in an RG fails.

WWN

World Wide Name. A unique identifier that identifies a particular PD.

CHAP

Challenge Handshake Authentication Protocol. An optional security

mechanism to control access to RTX through its iSCSI data ports.

iSNS

Internet Storage Name Service. This protocol allows automated discovery,

management, and configuration of iSCSI devices on a TCP/IP network.

The main circuit boards of the HDD carriers are susceptible to static electricity. Proper grounding is

strongly recommended to prevent electrical damage to the enclosure or other connected devices, including the computer host. Avoid all dramatic movement, tapping on the unit, and vibration.

Avoid placing the HDD carriers close to magnetic devices, high voltage devices, or near a heat

source. This includes any place where the product will be subject to direct sunlight. Do NOT allow water to make contact with the carrier or receiving frame.

Before starting any type of hardware installation, ensure that all power switches have been turned off

and all power cords have been disconnected to prevent personal injury and damage to the hardware.

To avoid overheating, RTX should be operated in a well-ventilat ed ar ea and in suc h a way that

sufficient airflow is maintained across the controller chips.

RAID

Use only hard drives that are in perfect condition. Avoid using drives that have ever developed bad

sectors during previous usage. This could lead to possible device failure or loss of data.

RTX supports SATA hard drives of various specifications and different capacities. However, we

recommend using drives of the same brand and type for optimal performance. If drives of different capacities are used in a RAID, the capacity of the smallest drive will determine how much of each drive is used. The additional capacity on the larger drives will not be used by the RAID.

RAID level 0 will allow you to use the full combined capacity of the drives, and offers the best data

transfer speeds. However, RAID 0 offers no protection for the data. If one drive fails in a RAID 0, the data on all of the drives is irretrievably lost. Before creating a RAID, investigate the various RAID types and choose the one that is best for your needs.

Always back up data before switching RAID types. Switching RAID types will destroy current

data. You must reformat your drives afterwards.

A RAID (Redundant Array of Independent Disks) is an array of multiple hard drives that are combined in a way that provides faster performance and/or data safety. Your RTX unit is capable of creating and managing several different varieties of RAID. You may choose your preferred RAID level based on factors such as disk capacity, desired data safety, and desired performance.

3.1 Summary of RAID Levels

RTX supports RAID Levels 0, 1, 3, 5, 6, 0+1, 10, 30, 50, 60, & JBOD. RAID Level 5 is most commonly used by those seeking an optimal balance of speed and data safety.

4 Introduction to iSCSI

4.1 What is iSCSI?

iSCSI is a technology that allows a data storage device to be accessed over a TCP/IP network using SCSI protocols. When your computer’s OS receives a request for data access, it generates a SCSI command and then sends an IP packet across a network or direct Ethernet connection. A software utility known as an iSCSI initiator is used to generate the SCSI commands. Such a utility must be installed on the computer before it can access an iSCSI storage device (See Section 8 for installation instructions).

4.2 What is the Benefit of iSCSI?

An iSCSI storage device can be placed anywhere throughout a network, so the device can reside at a great distance from the computer which accesses it. It is also a very fast connection when used on a gigabit network, achieving speeds of 100 megabytes (MB)/sec or more. The connection it uses (RJ45— standard Ethernet port) is commonly found on desktop and laptop computers, so there is no need to purchase potentially expensive host bus adapters to provide a connection.

4.3 What is iSCSI Not?

iSCSI storage devices are not Network Attached Storage (NAS) devices. They have no built-in server capabilities and therefore cannot be accessed by more than one computer at a time. Multiple computers can only access the data if the iSCSI device is first attached to a single computer which is then set up as a server.

5 Installation Steps

5.1 Hard Drive Installation

a) Pull the ejection handle on the TrayFree bay to open the bay door. b) Insert a bare SATA hard drive into the bay. Make sure it is label-side up with the SATA connection on

the drive inserted first.

c) Shut the bay door. d) You can optionally secure each bay door. Doing so is not necessary to operate RTX.

• For RTX410 and RTX610, Insert an RTX Key into its key lock and turn it 90 degrees clockwise.

• For RTX801-IR, use the Lock Tool to slide the lock to the “locked” position.

Sticker Card

Use the stickers on the provided sticker card to label each drive. This will prevent the drives from getting mixed up when they are removed from the bays.

5.2 Operating RTX

a) Connect RTX to a computer or network using the included Ethern et cable. Plug one cable into the “CH-

1” port. You can optionally plug a second cable into the “CH-2” port. The purpose of having multiple iSCSI channels is to provide redundancy/failover and increased performance.

b) Connect RTX to a power outlet with the included power cord. c) Install the hard drives into RTX (See Section 5.1). d) Flip the power switch on the rear of the unit to turn on RTX. e) If you have not yet configured RTX for access, refer to Sections 6, 7, and 8. Section 6 will tell you how

to connect RTX to your network or computer. Section 7 contains instructions for accessing the GUI and

creating a usable RAID set. Section 8 contains instructions on how to access RTX through an iSCSI initiator.

f) Format the drive. When a hard drive is first used with RTX, or when a RAID set has been created and the user connects to RTX through an iSCSI initiator, it will show up as a blank, unallocated drive. You’ll need to format the drive in RTX before you can use it See Section 9 for instructions on how to format the drive with Mac or Windows operating s ystem s . Note that formatting a drive will erase all data on the

drive, so be sure to back up your data b efore installing the hard drives into this enclosure and before beginning this operation.

5.3 Recovering from a Failed RAID

If one hard drive of a RAID set with data redundancy has failed or has been unplugged or removed, then the status of the RAID Group will report that the RAID is degraded and RTX will automatically search for a spare disk to rebuild the RAID. If none are found, RTX will search for a global spare disk. If neither is found, it will wait for the user to remove the failed hard drive and insert a working replacement.

6 Network Configuration

6.1 Connecting RTX to Your Network or Computer

a) Plug an Ethernet cable into the Config GUI port on the rear of RTX. b) Connect the other end of the Ethernet cable to your network. This usually means plugging it into a

router or hub. In an office environment, you may have a network jack built into your office wall. If a network connection is not available, you can connect the Ethernet cable directly to an RJ45 (Ethernet) port on your computer.

c) Connect the power cable to the rear of RTX and to a grounded electrical outlet. d) Turn on RTX’s power using the switch on the rear panel.

6.2 Using the LCD to Configure the Config GUI Port

RTX has both an LCD interface and a GUI. The LCD interface has only basic functionality and is mainly used to configure the IP address of the Config GUI port. Once the Config GUI has been configured, the GUI can be used to fully configure RTX.

6.2.1 Navigating the LCD menu

Use the four function keys, ▲ (Up), ▼ (Down), ESC (Escape) and ENT (Enter) to manipulate the LCD interface. After pressing ENT (Enter) key, you can use the ▲ (Up) and ▼ (Down) keys to select a function. If there is an alarm or error message, the LCD will display the related information.

6.2.4 Instructions for Differi n g Network Connection Types

DHCP-Enabled Network

On DHCP networks, a new IP address is dynamically assigned to RTX’s Config GUI port as soon as the network detects it. You can determine this address by checking the LCD interface on the front of RTX. It will appear in this format: xxx.xxx.xxx.xxx. Simply type this IP address into a web browser on your computer. This will access RTX’s GUI, which you will use to configure the unit.

Static Network a) Check your computer’s IP address, subnet mask, and gateway. Mac users can find this

information in System Preferences  Network.

To do this in Windows, open Network and Sharing Center in the Control Panel (Also called “View Network Status and Tasks” under the “Network and Internet” category). On the left pane, select “Change adapter settings”. Right-click on your network (likely called Local Area Connection) and select Properties. On the new window that opens, select “Internet Protocol Version 4 (TCP/IPv4)” and click the Properties button. Your computer’s IP address, subnet mask, and gateway will be displayed.

b) On the RTX LCD interface, press ENT and then scroll up or down to Change IP Setting. Press ENT.

c) Scroll up or down to find Static. Press ENT.

d) Change the IP address to closely match what your computer is using. Or, if you are on a

business network, have your IT administrator assign you an IP address. The IP address you select must NOT be in use by another device.

For example, if your computer's IP address is 192.168.0.9, you might change the RTX’s IP to

192.168.0.7. On smaller networks, each of the first three octets must be the identical to your computer’s IP address! When changing the IP address you'll notice that a box flashes over the digit to be changed. While the digit is selected, press ▲ (Up) or ▼ (Down) to change it. Press ENT to move to the next digit.

e) After the IP address is set, enter the subnet mask address exactly as it is shown on your computer’s TCP/IP settings.

f) Next, enter the gateway address exactly as it is shown on your computer’s TCP/IP settings.

g) Confirm the settings change. To confirm, press ▲ (Up) for “yes” and then press ENT again.

h) Type the RTX’s new IP address into a web browser on your computer. This will access the

RTX’s GUI, which you will use to configure the unit.

Direct Connection to a Computer

The instructions are similar to those for a static network (see above), except that your computer will not have an IP address assigned if it’s not a part of a network. Since RTX and your computer must have similar IP addresses, you will assign an IP address to your computer based upon the default IP address of RTX.

a) Check RTX’s LCD to find out the IP address of the Config GUI configuration port. It will appear

After making changes

in this format: xxx.xxx.xxx.xxx.

b) Next, change your computer’s IP address so that all but the last three digits match RTX ’s address. For example, if RTX’s IP address is 169.254.12.62, you might assign your computer the number 169.254.12.63 (assuming no other computer on the network is already using that number). The process of changing your computer’s IP address varies depending on its operating system.

Mac users can go to System Preferences  Network.

For modern Windows operating systems, open Network and Sharing Center in the Control Panel (Also called “View Network Status and Tasks” under the “Network and Internet” category). On the left pane, select “Change adapter settings”. Right-click on your network (likely called Local Area Connection) and select Properties. On the new window that opens, select “Internet Protocol Version 4 (TCP/IPv4)” and click the Properties button. By default, your computer is probably set to receive a new IP address automatically. Change the setting to manual configuration and then type in the IP address.

c) Using the same process as the previous step, change the computer’s Subnet Mask setting to match RTX’s Subnet Mask setting.

d) Finally, use RTX’s LCD interface to change RTX ’s Gateway setting. It should match the IP address you assigned to your computer. When changing the gateway address you'll notice that a box flashes over the digit to be changed. While the digit is selected, press ▲ (Up) or ▼ (Down) to change it. Press ENT to move to the next digit. After the gateway address is set, press ENT all the way to the end and confirm the settings change. To confirm, press ▲ (Up) for “yes” and then press ENT again.

e) Launch a web browser and type RTX’s IP address into the URL bar, as if it were a website. This will access RTX’s GUI, which you will use to configure the unit.

The tables below show example settings. The first table shows the type of settings that will appear by default. The next table shows how the settings might look after you’ve made changes.

RTX Computer

Connecting From Home to Office

RTX can also be used over the Internet. If you are connecting to an RTX at your office from home, you will need to contact your IT administrator to set up a VPN client in order to log in to the office network. Once you have logged in to the office network, you can access RTX just as if you were actually at your office (see instructions for DHCP-enabled Network, Static Network, or Direct Connection to a Computer, depending on how your office network is configured).

7 Using the GUI

You will use the web browser-based GUI to set up a RAID and create logical volumes on RTX. After setting up access to the GUI and accessing it through a web browser (see Section 6.2 for instructions),

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 10 -

CRU

the GUI’s main page should load, displaying a picture of RTX with several options to the left. When you click on any option, you will be prompted for a username and password. The default administrator username is "admin" and the default password is "1234."

7.1 GUI Indicators

The top right hand corner of the GUI window displays several indicators.

RAID light: Green indicates that the RAID is working properly. Red indicates a RAID error. If no

RAID is set up, the light will remain green.

Temperature light: Green indicates normal. Red indicates abnormal system temperature and

probable overheating.

Voltage light: Green indicates normal. Red indicates abnormal voltage status like a power surge

or a bad power supply.

Fan light: Green indicates that the fan is working properly. Red indicates a malfunctioning fan that

needs to be replaced. (only applies to RTX610-IR and 801-IR).

7.3 Manually Creating a Usable RAID Set

Use these sets of instructions to create a usable RAID set. To quickly create a RAID 0, 1, 3, 5, 6, or 0+1 set using the Volume Creation Wizard, see Section 7.6.1.

7.3.1 Manually Creating a RAID Group

To manually create a usable RAID set, you will first need to create a new RAID Group.

a) Click the “Create” button at the bottom of the page to open the RAID Group creation screen.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 12 -

CRU

b) Enter a name for the new RAID Group in the first field, and then select your desired RAID type or

JBOD from the dropdown box. CRU-DataPort recommends RAID 5 for maximum performance, capacity, and security. For more information on RAID, see Section 3. Click “Select PD” to select the drives that will be added to the RAID Group.

Note: Drives must be marked as Free Disks before they can be added to a RAID Group. To set drives to Free Disks, see Section 7.7.2, subsection “Modifying Physical Disks”.

c) All available Free Disks will be displayed. Check the drives that you wish to add to the RAID

Group, then click “Confirm”.

d) The selected Physical Disks will now be displayed in the RAID Group creation screen. Enable or

Disable Write Cache, Standby, Readahead, and Command Queuing based on your needs. Most RAID Groups will be fine with the default settings. Then click “Next” to proceed to the confirmation screen.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 13 -

CRU

e) On the confirmation screen, verify that the RAID level is correct and all of the disks you selected

are displayed under “RAID PD slot”, then click “Confirm” to create the RAID Group.

f) The RAID Group will now display on the main RAID Group screen. To finish manually creating a

usable RAID set, a Virtual Disk still must be created and a Logical Unit must be attached. Go to the next section, “Manually Creating a Virtual Disk”.

If you opted to create JBOD drives, skip to Section 8.3.3, “Manually Attaching a Logical Unit” as Virtual Disks have already been created for each JBOD drive.

7.3.2 Manually Creating a Virtual Disk

After a RAID Group has been created, you can create associated Virtual Disks. You must create at least one Virtual Disk to access the drives of RTX with a computer.

a) Click the “Create” button at the bottom of the page to open the Virtual Disk creation screen.

b) You will see the screen below. Fill in the information and then click “Confirm”. Each field is

explained below the picture.

RTX410/610/801-IR User Manual A9-468-0005 REV 1.0 - 14 -

CRU

Name

Enter a name for the Virtual Disk.

RG Name

Choose the RAID Group to which the Virtual Disk will be added.

Capacity

Enter the capacity of the Virtual Disk. The default uses the maximum capacity of the associated RAID Group. If you wish to create multiple Vir tual Disks on the selected RAID Group, you will need to reduce the capacity below the maximum so that there is space left on the RAID Group for additional Virtu al D is ks.

Stripe height (KB)

Determines how RTX organizes the RAID. Normally the default option is preferred.

Block size

Determines the minimum file size for files that will be stored on the Virtual Disk. Higher block sizes can result in more wasted space if many small files are saved to the drive, but are necessary to take advantage of high capacity RAIDs. If you are creating a Virtual Disk over

2TB in size for use with MacOS 10.4.x or older, or for use with Windows XP, you must increase the block size to 4096KB to take advantage of the full capacity of the Virtual Disk.

Read/Write

Allows selection of cache type. Normally the default option is preferred.

Priority

Determines the priority that RTX will give to RAID activities (rebuild and initialization) versus priority given to file transfers. “High prior ity” will result in slower file transfers during initialization, but provide for faster initialization.

BG Rate

Background Task Priority. The higher the number, the more priority will be given to background input/output.
