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.)
Order Number: EK–STWCT–UG. E01 1–1
StorageWorks 8505 8mm Cartridge Tape Drive
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 in StorageWorks documentation to refer to a device, such as tape or disk drive, that is installed in a device carrier.
StorageWorks Building Block, or SBB
, is used
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.
The actual compression ratio achieved depends on the type of data to be compressed. This guide assumes an average compression efficiency of 2:1.
NOTE
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.
Chapter 1 Introduction
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.
