Introduction

This chapter provides a product overview of the StorageWorks 8505 8mm Cartridge Tape Drive, outlines

its features, and describes the formats it can read and write.

1.1 Product Overview

The StorageWorks 8505 8mm Cartridge Tape Drive (Figure 1–1) is an enhanced 8mm

digital helical-scan cartridge tape drive, which is packaged in an industry standard

5.25-inch half-height form factor. The half-height size allows for ease of integration

across a multitude of platforms.

Figure 1-1 StorageWorks 8505 8mm Cartridge Tape Drive

1.2 StorageWorks Packaging Options for the Cartridge Tape Drive

The. StorageWorks 8505 8mm Cartridge Tape Drive is available as three packaging

options as follows:

• SWXTE-AA (Figure 1–1)

• SWXTE-AB (Figure 1–2)

• SWXTE-AC (Figure1–3)

Figures 1–1, 1–3, and 1–4 show the packaging options. (Chapter 2 provides information

about installing and configuring the options.)

StorageWorks 8505 8mm Cartridge Tape Drive

1–2 Order Number: EK–STWCT–UG. E01

Option SWXTE-AA is a configuration in which one or two 8mm tape drives is installed

in a device carrier, and the device is subsequently placed in a StorageWorks drive

expansion unit. Figure 1–2 shows one tape drive installed in a device carrier.

Figure 1–2 Option SWXTE-AA: One Tape Drive in a Device Carrier

NOTE

The expression

StorageWorks Building Block,

SBB

, is used

in StorageWorks documentation to refer to a device, such as

tape or disk drive, that is installed in a device carrier.

Option SWXTE-AB is a configuration in which a second 8mm tape drive is installed in a

device carrier. Note that the device carrier is shipped to you with both drives already

installed if options SWXTE-AA and SWXTE-AB are ordered at the same time. If option

SWXTE-AB is ordered after you already have option SWXTE-AA, the second drive is

installed in the top half of the device carrier as shown in Figure 1–3.

1.3 Support for Four Data Formats

The StorageWorks 8505 8mm Cartridge Tape Drive can read and write data in four

formats:

• EXB-8500c (compressed) format

• EXB-8500 format

• EXB-8200c (compressed) format

• EXB-8200 format

When writing in its default EXB-8500c (compressed) format, the 8mm tape drive

implements a powerful algorithm that enables it to compress user data at ratios of 2:1 or

greater. Assuming an average compression efficiency of 2:1, the tape can store up to

10 GBytes of data on a single 8mm data cartridge.

NOTE

The actual compression ratio achieved depends on the type of

data to be compressed. This guide assumes an average

compression efficiency of 2:1.

When writing in the non-compressed EXB-8500 format, the tape drive can store up to

5.0 GBytes of data on a single 8mm data cartridge.

When writing in the EXB-8200c (compressed) format, the tape drive can store up to

5.0 GBytes of data on a single 8mm data cartridge, assuming an average compression

efficiency of 2:1

When writing in the non-compressed EXB-8200 format, the tape drive can store up to

2.5 GBytes of data on a single 8mm data cartridge. Refer to Appendix B and C of this

guide for detailed data format information for your specific operating environment.

Table 1–1 lists the read and write compatibilty of several data formats with several 8mm

tape drives. Note that devices with names beginning "EXB" are produced by EXABYTE

Corporation; devices with names beginning "TKZ" are produced by Digital Equipment

Corporation. In the table, SWXTE represents all three packaging options of the

StorageWorks 8mm Cartridge Tape Drive.

1.4 Support for Partitioned Tapes

Some operating systems provide support for tape partitions. With these systems, the tape

drive can read and write tapes containing either one or two partitions. Partitions provide

an efficient way to maintain a directory on a tape without the risk of overwriting data

when updating the directory. For additional information, refer to the operating manuals

that support your system.

1.5 Enhanced Performance

Assuming an average 2:1 compression ratio, the tape drive can achieve a sustained

transfer rate of approximately 1 MByte per second when writing in EXB-8500c format.

The maximum SCSI data transfer rate is up to 5.0 MBytes/second for a synchronous

burst and up to 2.5 MBytes/second for an asynchronous burst. (Achievement of these

performance numbers is dependent on the system configuration into which this tape drive

is installed).

Data interchange is maintained through full read and write compatibility with the

EXB-8500c, EXB-8500, EXB-8205, EXB-8200, and EXB-8200SX 8mm Cartridge Tape

Drives.

1.6 Intelligent Data Compression

When writing in its default EXB-8500c format, the tape drive uses the established

Improved Data Recording Capability (IDRC) algorithm. Licensed from IBM, this

algorithm is a de facto standard in mainframe environments. It uses the EXABYTE

Compression Integrity Check™ feature to ensure that data is accurately compressed and

decompressed into the original form sent by the host computer.

The compression algorithm is completely contained in an EXABYTE proprietary

integrated circuit. When data compression is enabled by the user, the tape drive invokes

the compression algorithm intelligently, constantly monitoring the compression ratio to

determine whether compressing the data will actually decrease the size of the data set.

When compression is turned on, the tape drive sends compressed data to tape only when

it benefits the user's storage capacity and throughput.

1.7 Sophisticated Error Correction Procedures

The tape drive performs on-board error correction code (ECC) and error-recovery

procedures, along with full read-after-write verification to ensure data integrity. The

drive also contains a logical-block-CRC (cyclic redundancy check) feature. By adding

two bytes of CRC data to every logical block on a compressed format tape, the drive can

check that user data is compressed and decompressed accurately.

1.8 Additional Features

The tape drive contains a single-ended SCSI controller. Additional features include

SCSI-2 compatibility, synchronous data transfer, an integrated 1-MByte speed-matching

buffer, full disconnect/reconnect arbitration support, and logical block packing. The tape

drive is an easily integrated solution to your journalizing, archiving, data interchange,

software distribution, imaging, data acquisition, and backup/restore needs.

Installation and Initial Power ON

This chapter refers you to the installation document you need. It also provides the steps you should follow

for the initial power on of the StorageWorks 8505 8mm Cartridge Tape Drive.

2.1 Unpacking the StorageWorks 8505 8mm Cartridge Tape Drive

CAUTION

If the current environment differs from the storage

environment by 15° or more, allow the Cartridge Tape Drive to

acclimate to the current environment for at least 12 hours.

The cartridge tape drive's packaging is designed to protect the drive from potentially

damaging condensation. If the drive has not acclimated in its packaging for at least 12

hours, serious damage to the device can occur.

Unpack and inspect the contents of your shipment. In addition to this guide, it should

contain the following items:

• One SWXTA-AA 10 GB, 8mm helical-scan cassette tape drive

• One 8mm cassette tape

• One head-cleaning cassette

• StorageWorks SBB user's guide

Also, check the contents for damaged components. Notify your vendor immediately if

any items are damaged. Keep all boxes and packing material for reshipment.

2.2 Installation Documents

The 8mm Cartridge Tape Drive is available as three different options. The following list

shows the option numbers and gives the title of the documents that describe installation

or configuration for that option.

• SWXTE-AA: This option number identifies a configuration in which one or two

cartridge tape drives is installed in a device carrier, and the device carrier is

subsequently placed in a StorageWorks deskside (or larger) storage expansion unit.

For instructions on installing or replacing the drive in the device carrier, refer to the

document titled StorageWorks Building Blocks User's Guide. For instructions on

placing the device carrier in a deskside storage expansion unit, refer to the document

titled StorageWorks Expansion Storage Pedestal User's Guide.
