reduce the chance of ESD damage.

Preparing the Mounting Bay

Caution: To avoid personal injury or damage to the server or tape
drive, ensure that the server is disconnected from the main power supply while you install the drive.
1 Assemble the necessary tools and materials:
• Phillips screwdriver
• Your server manuals (for reference during installation)
2 Perform a normal system shutdown and turn off the server and any
connected peripherals.
3 Remove the cover and front panel from the server, as detailed in
your server’s documentation.
As you work inside the server, you may have to disconnect other signal cables or power cables from other devices to maneuver the new drive into place. If you have to do this, make a note of their position and connections so you can put them back correctly later.

4 You are now ready to install your tape drive.

Attaching Mounting Hardware

If your server requires special rails or other hardware to install the tape drive, mount them on the tape drive now. If your server does not require special mounting hardware, proceed to Installing the Tape Drive
Caution: Static electricity can damage electronic components.
Always wear an antistatic wrist strap if one is available. If not, after you have disconnected power from the server and removed the cover, touch a bare metal part of the chassis. Similarly, touch a bare metal part of the drive before installing it.
Note: If mounting hardware is supplied with your tape drive, it may
not be exactly the same as shown in the illustrations.
Chapter 2 Installing Internal Tape Drives
Attaching Mounting Hardware
.
Different models of server require different mounting methods. The server may also incorporate a locking mechanism to hold the tape drive in place.
Please check your server documentation to ascertain the correct method of mounting and to check whether mounting hardware is provided with the server.

Mounting Rails Some servers require mounting rails. These may be metal or plastic rails

attached to the filler panel of the server's drive bay.
1 Use a regular Phillips screwdriver to attach the appropriate rails. Use
M3 screws 5 mm (0.2 in).
Ensure you have the M3 screws. The rails may be attached to the filler panel by screws of a different thread/size type and these should not be used. If in doubt, refer to your server documentation.
Quantum DAT 320 User’s Guide 10
Chapter 2 Installing Internal Tape Drives Installing the Tape Drive
Mounting Screws
Other server models only require the use of special locating screws with no mounting rail.
1 Use a screwdriver to attach the appropriate screws. You may need
Figure 3 Attaching Mounting Screws
to purchase the M3 screws separately. Position the screws (see
Figure 3
).
2 Attach the appropriate mounting hardware. Refer to the
manufacturer’s documentation for instructions.
• If you are installing on a server that requires a tray, place the tape drive in the tray.
• If you are installing in a server that requires mounting rails, fasten the rails to the tape drive.
• Some servers have snap-on mounting rails attached to the filler panel. These can be removed and attached to the tape drive with screws.

Installing the Tape Drive

Slide the tape drive into the open bay aligning the tray or rails with the slots in the bay (see Figure 4
11 Quantum DAT 320 User’s Guide
).
Figure 4 Installing the Tape Drive
Chapter 2 Installing Internal Tape Drives

Attaching USB Cable

If your server does not use mounting hardware, check that the holes in the chassis are aligned with the holes in the side of the tape drive.
Do not secure the drive at this point because you may have to move the drive to get the cables into place.

Using the Appropriate Media

The Quantum DAT 320 drive uses data-grade cartridges, which comply with ANSI specifications listed in the “3.81 mm Helical-Scan Digital Computer Tape Cartridge for Information Interchange,” ANSI X3B5/89-156 standard.
Quantum DAT 320 User’s Guide 24
Chapter 4 Operating Your Tape Drive WORM Cartridges
Table 3 Matching Drives with the Media They Support
Quantum recommends using Quantum DAT 320 cartridges:

WORM Cartridges

The Quantum DAT 320 tape drive includes support for both rewriteable and Write-Once, Read-Many (WORM) data cartridges. WORM cartridges provide for an enhanced level of data security against accidental or malicious alteration of data on the tape cartridge. The WORM data cartridge can be appended to maximize the full capacity of the tape cartridge, but the user will be unable to erase or overwrite data on the cartridge. Any attempt to modify a WORM cartridge to enable writing over existing data will result in the media becoming permanently write­protected. It should still be readable in a WORM drive, depending upon the severity of the tampering, but no further appended backups will be possible.

DAT 160 155 meters
• DAT 320 media cartridge part number:MR-D7MQN-xx
• DAT 320 cleaning cartridge part number: MR-D7CQN-xx
In order to use these cartridges, your backup software application needs to support DAT 320 WORM cartridges. Please check with your software vendor to be sure.

DAT 320 Tape Drives and Encryption

Your DAT 320 tape drive includes hardware capable of performing data encryption at full speed while writing data, and decrypting when reading. Encryption is the process of changing data into a form that
25 Quantum DAT 320 User’s Guide
Chapter 4 Operating Your Tape Drive
DAT 320 Tape Drives and Encryption
cannot be read until it is deciphered, protecting the data from unauthorized access and use. DAT 320 tape drives use the strongest version of the industry-standard AES encrypting algorithm to protect your data (IEEE P1619.1-2007 compliant GCM-128-AES-256).
To make use of this feature you need:
• A backup application that supports hardware encryption
• DAT 320 GB media; no hardware encryption will be performed when writing earlier generations of tape

When should I use encryption?

How do I enable encryption?

When will I be asked to enter the key?

Your company policy will determine when you need to use encryption. For example, it may be mandatory for company confidential and financial data, but not for personal data. Company policy will also define how encryption keys should be generated and managed. Backup applications that support encryption will generate a key for you or allow you to enter a key manually.
Note: Encryption with keys that are generated directly from
passwords or passphrases may be less secure than encryption using truly random keys. Your application should explain the options and methods that are available. Please refer to your application's user documentation for more information.
Hardware encryption is turned off by default and is switched on by settings in your backup application, where you also generate and supply the encryption key. Your backup application must support hardware encryption for this feature to work.
Encryption is primarily designed to protect the media once it is offline and to prevent it being accessed from another machine. You will be able to read and append the encrypted media without being prompted for a key as long as it is being accessed by the machine and application that first encrypted it.
There are two main instances when you will need to know the key:
• If you try to import the media to another machine or another instance of the backup application
Quantum DAT 320 User’s Guide 26
Chapter 4 Operating Your Tape Drive Handling Cartridges
• If you are recovering your system after a disaster

What happens if I don't remember the key?

Does encryption affect tape drive performance?

Does the tape drive encrypt media in an earlier format?

If you are unable to supply the key when requested to do so, neither you nor Quantum Support will be able to access the encrypted data.
This guarantees the security of your data, but also means that you must be careful in the management of the encryption key used to generate the tape.
Caution: You should keep a record or backup of your encryption
keys and store them in a secure place separate from the computer running the backup software.
Hardware encryption can be used with or without compression and without speed or capacity penalties.
No. Encryption is supported only on DAT 320 GB media.
DAT 320 GB tapes encrypted on DAT 320 tape drives can be read on any compatible DAT 320 tape drive that supports hardware encryption.
DAT 320 tape drives can read DAT 160 GB media and write DAT 160 GB media, but hardware encryption is not supported on these formats.

Problems with Cartridges

If you experience any problems using Quantum branded cartridges, check:
• The cartridge case is intact and that it contains no splits, cracks or damage.
• The cartridge has been stored at the correct temperature and humidity. This prevents condensation. See the insert included with the tape cartridge for storage conditions.
• The write-protect switch is fully operational. It should move from side to side with a positive click.

The Cartridge is Jammed
Chapter 5 Troubleshooting
Problems with Cartridges
If the cartridge is jammed or the backup application is unable to eject it, you can force eject the cartridge. Once the cartridge is successfully ejected, it is good practice to upgrade the firmware. If the failure occurs regularly, contact customer service at www.quantum.com/
ServiceandSupport/Index.aspx.
1 Either press and hold the Eject button on the front of the tape drive
for at least 15 seconds. Or press the Eject button three times within 5 minutes.
2 Wait for the cartridge to be ejected. The drive waits until 35 seconds
have passed from the time of the first press, to give the normal eject procedure a chance to proceed. After this period, it immediately releases the tape and ejects the cartridge, regardless of what operation it was performing. It is important that you allow sufficient time for the drive to complete this process. If you interrupt it, you may damage the media or the tape drive. The drive is then reset as though you had turned the power off and then on again.
You may lose data if you force eject a cartridge. The tape may also become unreadable because an EOD (End of Data) mark may not be properly written.

USB Configuration Guide

USB in Quantum DAT Devices

The Quantum DAT tape drive is a USB 2.0 logo certified device. It supports the high-speed USB transfer rate with a theoretical maximum transfer of over 50 MB/s. (The actual backup rate will be less. This is defined by the transfer rate of the tape drive and the compressibility of the data.)
To benefit from the high-speed performance of the USB 2.0 interface, the USB Quantum DAT tape drive should be connected to its host system via a USB 2.0 port. Any USB hubs between the tape drive and the system port should also be USB 2.0 compliant.
Appendix B
To maximize tape drive performance, minimize the use of other USB devices when using the USB tape drive.

USB Terminology

The Universal Serial Bus, USB, is a communication interface where an intelligent host controls all the network activity. A command from the host to a particular device is broadcast to all devices on the network. A device waits for a command addressed to itself and then responds as requested.
Quantum DAT 320 User’s Guide 44
Appendix B USB Configuration Guide USB Terminology
The host determines how much of the overall USB network bandwidth a given device can use at any time. Any given USB network has only one host.
Hubs act as command repeaters and multipliers. This allows many devices to be supported by one host. A host command can arrive at the upstream port of the hub and be transmitted via the downstream ports to many other device and hubs. (Likewise, device commands arriving at a downstream port are also repeated upstream.) There is a special hub called a root hub. The root hub’s upstream port is connected directly to the host. All USB systems have a root hub. This is why a system typically has more than one USB port. All the USB ports on the system are connected to the host system via the root hub.
USB devices are not treated equally by the host.
• Periodic devices, which consist of interrupt and isochronous devices, are given a higher priority than bulk transfer devices.
• Interrupt devices, such as keyboards and mice, typically send brief but important input information to the system.
• Isochronous devices, such as web cameras, typically require timely transmission of data, such as a video stream.
• Bulk transfer, such as printers and CD-ROM, must receive or transmit 100% accurate data. But how fast or often the data is transmitted is not as important as the accuracy of the data.
The host will give network bandwidth priority to periodic devices and will share any remaining bandwidth equally among any active bulk transfer devices.
USB supports many types of devices and three data transfer rates, low speed, full speed, and high speed. (A keyboard does not need to transfer data to the system at the same speed as a cable modem.)
The transfer speed capabilities of a device are often referred to by the USB specification revision in which the transfer rate was defined. Therefore a USB 2.0 Hub will support high, full and low speed, but a USB 1.1 hub will only support full and low speed.
The USB specification was developed and is maintained by the USB organization. The USB organization also conducts a certification program. The USB organization will issue the USB logo to a device, which has passed a series of tests that verify the device has correctly implemented the USB interface, as defined by the USB specification. There are many types of USB logos depending on which features of the
45 Quantum DAT 320 User’s Guide
USB specification a device supports. A USB 2.0 logo-ed device correctly supports high, full, and low speed data transfer.

Setting Up a USB Network

USB is very user friendly. The interface automatically assigns addresses to devices; you simply need to connect a USB device to a USB port on a system using a USB cable. If you have many USB devices or need to place a device away from your system, you may place up to a maximum of five USB hubs between the device and host system and connect them with additional cables.
If you are using a high-speed (USB 2.0) device, make sure that the USB host at the system and all the hubs between the device and host support high-speed (USB 2.0) transfer.
When using a bulk transfer device, such as a tape drive, do not use other USB devices that will place restrictions on the USB bandwidth available to the bulk transfer device.
Appendix B USB Configuration Guide
Setting Up a USB Network
If several USB device requiring large amounts of the USB network bandwidth are to operate simultaneously, an additional host must be added to the system. Each device must then be placed into the separate networks starting at the different hosts. An additional host is typically a new USB HBA, which plugs into the host system’s PCI slot, creating a new USB host that resides on the network.
Note: If several USB adapters are placed into a system, demands on
the bandwidth of the system bus will constrain the USB devices’ performance.
Always use USB logo-ed components in your USB network. This is the best and easiest method to ensure reliable operation.

USB Cables

USB cables are available in a variety of lengths. The maximum cable length is 5 meters. If you need to place a USB device further than 5 meters from the system, you must use a hub.
Do not use USB cable extenders or couples. These are not recognized or approved by the USB organization. The USB specification does not allow their use and they are likely to reduce the reliability of the USB network or cause it not to work completely.
Internal and external USB devices use the same USB cables.
