How do I connect the drive to my server?

LTO—5 and LTO-4 tape drives are available with a SAS or FC interface.

The LTO-4 internal tape drive is also available with a SCSI interface.

Interface specifications and requirements for Fibre Channel drives

The Fibre Channel tape drive can be connected directly to the server with

a host bus adapter (HBA) or through a storage area network (SAN).

Table 1-1 FC drive interface speeds

Supported speedsLTO generation

1 Gb, 2 Gb, 4 GbLTO-4

2 Gb, 4 Gb, 8 GbLTO-5

If you plan to connect the tape drive directly to the server, you will need a 2

Gb or 4 Gb Fibre Channel HBA. A 4 Gb HBA is recommended for all

supported drive types due to performance requirements. Check http://

www.tandbergdata.com to verify that your HBA is supported on your server

and qualified for the tape rrive. A 1 or 2 Gb HBA might result in performance

degradation when backing up highly compressible data.

In a SAN installation, all switches between the host and the tape drive must

be of the appropriate type. A 1 or 2 Gb switch in the path may result in

performance degradation. Configure zoning so only the backup servers may

access the tape drive.

Interface specifications and requirements for SAS drives

Table 1-2 SAS drive interface speeds

Supported speedsLTO generation

1.5 Gb, 3 GbLTO-4

1.5 Gb, 3 Gb, 6 GbLTO-5

High quality SAS cables rated at the transfer rate of

the SAS components are required. Always verify that

Caution

the SAS cable you are using is rated for the data

transfer speed of the interface of your components.

SAS cables described as "equalized" may not support

6 Gb/s data rates and should not be used with LTO-5

1019

Chapter 1–Before you start

tape drives unless these cables are verified for 6

Gb/s data rates. For optimum performance, only use

cables of the length specified as qualified for your

products.

Interface specifications and requirements for SCSI drives

Use an LVDS-compatible ribbon cable to connect the tape drive to a spare

68-pin, high density (HD), wide SCSI connector on the host server. The

cable must be terminated. The following guidelines apply:

• For optimum performance the drive should be the only device on the

SCSI bus.

• Always terminate the SCSI bus.

• Do not attach the drive to the same SCSI bus as your disk drive or to a

RAID controller (unless you are connecting to a server with a Smart Array

6i RAID controller).

You will need a properly installed and configured SCSI host bus adapter

(HBA) or a built-in SCSI controller on your server and a suitably-rated SCSI

cable.

Always refer to http://www.tandbergdata.com to ensure

that you are connecting to a supported HBA running the

recommended firmware version.

Note:

Why is the SCSI bus type important?

The SCSI bus type determines the speed at which data can be transferred

between devices on the bus and the maximum length of cable that can be

used. The drives support a burst transfer rate of 160 MB/sec. To benefit

from this level of performance, it is important to ensure that the drives are

connected to a SCSI bus of a similar or higher specification. This means

that you need:

• An Ultra160 or Ultra320 SCSI bus. If you attach the drive to a lower

specification SCSI bus, it will still work but data will not be transferred

as quickly.

• LVD-rated SCSI cabling and terminators. The LVD interface enables

the data to be transferred at the drive's maximum rate.

The drives are not compatible with high voltage differential

(HVD) SCSI devices.

Your LTO tape drive

Power specifications

Power for the LTO-5 SAS internal tape drive is supplied through the SAS

cable. For all earlier models of LTO SAS tape drive and for all SCSI and FC

tape drives, a separate power cable is required, see http://

www.tandbergdata.com.

For a detailed product specification, please refer to http://

www.tandbergdata.com.

Drivers

The manufacturer's Tape driver is suitable for use in most applications, but

refer also to the documentation of your software application to ensure you

are using the recommended driver.

On Windows systems, we strongly recommend that you use the installer

package supplied by your manufacturer to install the drivers. Updates to the

drivers may be provided from time to time on http://www.tandbergdata.com.

We recommend that these are installed after using the installer package.

On Linux and UNIX operating systems, drivers are included with the operating

system and should be loaded automatically. To upgrade drivers we

recommend that you patch to the latest version of the operating system.

Backup software

For optimum performance it is important to use a backup application that is

appropriate for your system's configuration. In a direct attach configuration,

where the tape drive is attached to a standalone server, you can use backup

software that is designed for a single server environment. In network

configurations you will need backup software that supports enterprise

environments.

Further details about suitable products can be found on http://

www.tandbergdata.com. It is important to check for software compatibility

and install any recommended upgrades.

Certain backup applications require you to use their own

Tape driver instead of the manufacturer's Tape driver.

Enabling encryption

The LTO-5 and LTO–4 tape drive includes hardware capable of performing

data encryption while writing and data decryption while reading, both at full

speed. This is only possible with Ultrium 3 TB and 1.6 TB media, respectively.

See also “LTO-5 and LTO-4 tape drives and encryption” on page 55.

If you wish to make use of the encryption capability, you must enable this

feature via the backup software application. Refer to your supplier to find

out which applications support this advanced data protection capability.

Installing an internal LTO

tape drive

If you are installing an external LTO tape drive, please refer to

“Installing an external tape drive” on page 37.

Always refer to http://www.tandbergdata.com to find out

which HBAs and cables are appropriate for your

combination of server and tape drive.

Note:

• “Prepare mounting bay” on page 19

• “Attach mounting hardware” on page 21

• “Install drive” on page 22

• “Connect SAS and power cables to an LTO-5 tape drive” on page 24

Prepare mounting bay

You need one industry-standard, 5¼-inch, half-heightfull-height bay in which

to install the LTO tape drive.

To avoid personal injury or damage to the server or

tape drive, ensure that the server is disconnected

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.

1. Assemble the necessary tools and materials:

• Phillips screwdriver

• Flat-bladed screwdriver (if your server uses slotted screws)

• Torx screwdriver (if your server uses torx screws)

• 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.
