HP StorageWorks DAT models

This guide describes how to install and operate the following HP StorageWorks DAT rackmount tape drive models:

•HPStorageWorksDAT72

•HPStorageWorksDAT40

Which operating systems are supported?

HP StorageWorks DAT drives can be connected to servers running under Windows®, NetWare, UNIX, Tru64 and Linux. Refer to the “HP StorageWorks Tape Software Compatibility” topic on our World Wide Web site ( information about the operating system versions that are supported.

Which rackmount systems can I use?

HP StorageWorks DAT removable tape drives are used in conjunction with the HP Tape Array 5300 system, which can be used with both full-height and half-height tape drives. It will hold up to four HP StorageWorks DAT tape drives. The tape array is designed to be installed into HP, IBM and other compatible 19” rackmount systems. It must be properly installed and configured. Refer to your tape array documentation for further details.

Airflow requirements

www.hp.com/go/connect) for more

The HP Tape Array 5300 is designed to provide adequate airflow for up to four half-height or up to two full-height tape drives. As long as the tape array is fully populated, it will provide adequate airflow for your HP StorageWorks DAT tape drives. If you have unused bays in the tape array, you must install the blanking plates provided with the tape array. This ensures that there is adequate airflow to the drives. See the documentation with the tape array for details on installing blanking plates.

You should ensure that ventilation is adequate at the front and rear of the tape array.

How do I connect the drive to my server?

The following guidelines apply:

• For optimum performance the drive should be the only device on the SCSI bus.

• If you daisy-chain devices, make sure that devices are of the same SCSI type and that each device on the same SCSI bus has a unique SCSI ID and is terminated appropriately. Do not daisy-chain more than two devices on the same SCSI bus (for example, two LVD Wide Ultra drives).

• Always terminate the SCSI bus.

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

The individual tape drives are connected to their host server via the high density LVD/SE SCSI connectors on the back of the tape array. They do not require any SCSI cables to plug into the tape array. However, suitably-rated cabling and terminators are required to connect the tape array with the SCSI host. You will need a properly installed and configured SCSI host bus

adapter (HBA) or a built-in SCSI controller on your SCSI host with a spare low voltage differential (LVD) SCSI port and LVDS-compatible cables and terminators. See “Checking the SCSI connection” on page 9.

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 40 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 Ultra Wide, Ultra2 Wide, Ultra3 (160) or Ultra4 (320) SCSI bus. Ultra Wide SCSI

supports the maximum bus speed of 40 MB per second, Ultra2, Ultra3 and Ultra4 SCSI exceeds this.

• LVD-rated SCSI cabling and terminators. The LVD interface enables the data to be

transferred at the drive's maximum rate and provides a maximum cable length of 12 meters.

If you attach the drive to a lower specification SCSI bus, it may still work but data will not be transferred as quickly and you will need to use shorter cable lengths.

Note The drives are not compatible with high voltage differential (HVD) SCSI devices.

How can I check the SCSI bus type and SCSI ID?

For many operating systems, you can install HP Library & Tape Tools from www.hp.com/

support/tapetools

configuration (see page 29). This will provide information about the SCSI bus and the SCSI IDs in use. See also the SCSI topic in the electronic User’s Guide on the HP StorageWorks Tape CD-ROM for other ways of checking the SCSI bus type.

and run the “Install Check” to check your server’s current SCSI

Do I need additional items for installation?

• You will need to order the correct size SCSI cables and terminators to suit the particular configuration of your tape array. Cable and terminator options are listed at the HP tape array support web site: local HP sales office. Refer to your tape array’s Getting Started Guide for details of how to install SCSI cables and terminators on the rear panel of the tape array. The latest version of this document can also be downloaded from

• If you do not have a spare, suitably rated SCSI connector on your server, you must install a new HBA (also known as a SCSI card). This should be of an Ultra Wide or higher SCSI specification. We recommend that a 64-bit Ultra 3 (160) HBA is used. You will need to purchase and install the new HBA into an unused, 64-bit PCI expansion slot within your server before installing your tape drive. (The kit can also be installed in a 32-bit PCI expansion slot, but performance may be degraded.)

Backup software and drivers

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. HP, Veritas, Legato, Yosemite and Computer Associates all provide suitable products. Further details about these and other products that may be appropriate can be found on our connectivity web site.

Checking the SCSI connection

Use the following questions to help you check your SCSI connection. Many users can use HP Library & Tape Tools to check the SCSI bus type, see page 29. If you answer ‘Yes’ to all these questions, you are ready to install your tape drive. If you answer ‘No’, you will probably need to purchase and install additional items. For compatibility and product details, go to

www.hp.com/go/connect.

1 Is there a spare SCSI port on

your server?

Yes

2 Is the SCSI bus type correct

for the SCSI specification of the drive?

Yes

3 Will the drive be the only

device on the bus? This is the recommended configuration. Do not connect to a RAID controller or the same SCSI bus as your disk drive.

Yes

4 You are ready to install the

drive.

Purchase and install one of the recommended HBAs into an unused 64-bit PCI expansion slot. (The HBA can also be installed in a 32bit PCI expansion slot, but performance may be degraded.)

See table below. If the SCSI bus differs from the recommended specification for the drive, performance of either the drive or the bus may be impaired. Consider replacing your card with one of the recommended HBAs.

If you have an Ultra HBA, performance may be impaired. Consider installing (if you have a spare PCI slot) or replacing your card with an Ultra 2, Ultra 3 (160) or Ultra 4 (320) HBA.
