Alex,

I was looking at an eBay listing a while back that was titled "DIGITAL
DEC TLZ06-AA 8GB EXTERNAL TAPE DRIVE", this description is incorrect based
upon description?

I would say the description the posted is incorrect. One could 'market' the
aforementioned device as 4GB (albeit compressed) or 2GB (uncompressed), the
bolder marketer may simply say 4GB. I believe however, that marketing a
TLZ06-AA as 8GB would be incorrect.

However for any legal matters, or definitive statements on the matter, I
would recommend you undertake your own independent research.

TLZ06 Cassette Tape Drive Product

Description

1.1 OverviewThe TLZ06 cassette tape drive provides you with high capacity, off-line data
storage. Depending on the 4 mm data cassette tape used, the unit can
typicallystore:

Tape Type (see NOTE 1.) No Compression CompressionTLZ04-CA (60 m) 1.3 GB 2.6 GB

TLZ06-CA (90 m) 2.0 GB 4.0 GB (see NOTE 2.)


------------------------------------------------------------

NOTE
------------------------------------------------------------


1. The TLZ06 is compatible with TLZ04 (60 m) cassette tapes in thenoncompressed
mode only.2. The 4.0 GB measurement is typical for a 2-to-1 data compression
ratio, but the actual ratio is dependent on the data.------------------------------------------------------------


The maximum time to backup (read or write) on a TLZ06 cassette tape in acontinual
(streaming) mode is system dependent. The efficient use of streamingmode
is determined by your operating system. Please refer to your systemsoftware
documentation.

TLZ06 Cassette Tape Drive Product Description 1-1



1.1.1 System SupportAs of this printing, the TLZ06 drive is supported by VAXstation systems and
DECstation systems. Your particular system must have a standard SCSI(small
computer system interconnect) port, or a KZQSA (Q-bus to SCSIadapter).

VAXstation systems can use the VMS or ULTRIX operating systems.DECstation
systems use the ULTRIX operating system. Consult with yourDigital
sales support person for operating systems supporting this device.

1.2 Design FeaturesThe TLZ06 cassette tape drive uses state of the art technology. The TLZ06
cassette tape drive's design incorporates both digital data storage (DDS)
anddigital
audio tape (DAT) recording technologies.

1.2.1 What is Digital Audio Tape (DAT)?Digital audio tape (DAT), such as TLZ06 cassettes, takes advantage of the
TLZ06 tape drive's helical scan technology. This technology allows data tobe
stored diagonally on tape. As such, DAT allows more data to be stored ontape.
Also, DAT recording minimizes ``crosstalk,'' providing you with more dataintegrity.

1.2.2 What is Digital Data Storage (DDS)?Digital data storage (DDS) uses a recording format that supports the use of
digital audio tape for computer applications. The DDS/DAT format allowsyou
to back up 2 gigabytes of data in approximately 3 hours minimum withno
operator intervention. In addition, this format has three levels of errorcorrection,
which ensures high data integrity.


------------------------------------------------------------

NOTE
------------------------------------------------------------


Use of Non-DDS media may result in degraded drive performance andis
not recommended by Digital Equipment Corporation.------------------------------------------------------------

Installing the Tabletop Drives

2.1 GeneralThis chapter shows you how to install the TLZ06-DA tabletop cassette tape
drive or TLZ6L-DA tabletop auto loader on systems with an external SCSIconnector.
Read the following sections to complete the installation.

2.2 Shut Down, Halt, and Power Off the SystemIf you are installing a TLZ06-DA tabletop cassette tape drive or TLZ6L-DA
tabletop auto loader on a running system, have your system manager performthe
following steps:1. Shut down the operating system.

2. Halt the system.3. Set all system power switches off.

Installing the Tabletop Drives 2-1



2.3 Selecting the SCSI AddressTo familiarize yourself with the TLZ06 drive:

1. Refer to Figure 1-1 for the location of the buttons, switches, and
connectorson
the tabletop drives.2. Note that all connections are made at the rear of the drive.

Your system uses a SCSI ID switch (Figure 1-1) to identify, or address, thedrive.
The SCSI ID is factory set at 5. If you are installing the drive on asystem
that is already using SCSI ID 5, use any available SCSI ID. (You mayhave
to consult your system manager.)To set/change the SCSI address:

1. Locate the SCSI address switch at the rear of the drive.2. Select the SCSI address for the drive:

· TLZ06-DA -- Press the + or - button until the desired address (0through
7) appears in the window.· TLZ6L-DA -- Set the switches according to Table 3-1.


------------------------------------------------------------

NOTE
------------------------------------------------------------


If you are installing any other drive variant, refer to Chapter 3.Turn off all power before connecting the cables and the terminator.

The drive must be turned off and then on for switch settings to takeeffect,
or a SCSI bus reset must be received.------------------------------------------------------------


2-2 Installing the Tabletop Drives



The tabletop drives provide two SCSI connectors to allow daisy chaining.Either
connector can connect to the host computer or any SCSI device in adaisy
chain.· If the tabletop is the last drive in the chain, a single interface cable
isattached
to one connector and a SCSI terminator (PN 12-30552-01) isinstalled
in the other connector.· If the drive is within the chain, the interface cable from the preceding
device is connected in one connector; an interface cable is also connectedfrom
the other connector to the following device.


------------------------------------------------------------

NOTE
------------------------------------------------------------


Make sure that the last SCSI device on the bus is terminated correctly.------------------------------------------------------------


2.4 Connecting a SCSI Signal Cable -- Drive to SystemIf you are connecting a TLZ06-DA drive or TLZ6L-DA auto loader
directly to your system, you should use the SCSI signal cable suppliedas
part of your system installation kit.If you do not have this cable, contact your Digital sales representative.
Youshould
use a cable supplied by Digital Equipment Corporation. Failure to doso
can result in degraded performance of your tabletop drive.To connect a SCSI cable -- drive to system -- perform the following:

1. Connect one end of the cable to the system SCSI connector.2. Connect the other end of the SCSI signal cable to either SCSI connector
onthe
rear of the TLZ06-DA drive or TLZ6L-DA auto loader.3. Secure the SCSI cable by snapping the wire cable clamps (on either side
ofthe
SCSI connector) into place.4. Connect the SCSI terminator to the other SCSI connector on the rear of
the TLZ06-DA drive or TLZ6L-DA auto loader.5. Secure the terminator by snapping the wire cable clamps (on either side
ofthe
SCSI connector) into place.

Installing the Tabletop Drives 2-3



2.5 Adding Another Tabletop Drive -- Drive to DriveIf you have one SCSI device already connected to your system, you can
connectthe
TLZ06-DA drive or TLZ6L-DA auto loader to that device. For drive todrive

Preventive Maintenance and Problem

Solving

This chapter describes preventive maintenance and problem solving for theTLZ06
cassette tape drive. Preventive maintenance involves periodic headcleaning.
Problem solving is described in Table 6-1.Statistics show that over 90% of drive-related problems are associated with
themedia.
Therefore, Digital Equipment Corporation strongly recommends thatyou
follow the instructions for handling cassette tapes and cleaning the headsof
the drive.

6.1 Cleaning the HeadsThis section shows you how to perform TLZ06 head cleaning. The heads are
the components that physically read and write data to and from the media (inthis
case, a cassette tape).Digital Equipment Corporation recommends that you perform the
head cleaning procedure about every 2 weeks, or after every 50 hoursof
drive usage.Under normal conditions, it should not be necessary to exceed this
cleaning schedule. If a particular data cassette causes problems, trychanging
to another data cassette.

Preventive Maintenance and Problem Solving 6-1




------------------------------------------------------------

CAUTION
------------------------------------------------------------


Never attempt to clean the heads in a manner other than describedherein.
Doing so will void the product warranty.------------------------------------------------------------


To clean the heads, use the head cleaning cassette as follows:1. Press the power switch ON to apply power to the drive.

2. Insert the head cleaning cassette (PN TLZ04-HA) into the drive.3. With the head cleaning cassette inserted, the drive automatically
executes head cleaning. The drive ejects the head cleaning cassetteafter
approximately 30 seconds.4. Locate the card enclosed with the head cleaning cassette. Place a check
mark on the card every time you use the head cleaning cassette.Under normal conditions, the head cleaning cassette is used for about
25 cleanings. Additional cassettes are available from your Digital salesrepresentative
or DECdirect.If the head cleaning cassette has been overused, both the Cassette and
the Write-Protect LEDs will flash. Press the eject button to remove thecleaning
cassette. No cleaning action will have occurred.

Enabling/Disabling Data Compression

Under ULTRIX and VMS

B.1 ULTRIX TLZ06 Compression and NoncompressionModes

The default mode for the TLZ06 tape drive is noncompression mode. To usethe
TLZ06 tape drive in compression mode, specify the device as:/dev/rmt?h or /dev/rmt?m

To use the TLZ06 tape drive in noncompression mode, specify the device as:/dev/rmt?1 or /dev/rmt?a

B.2 ULTRIX DUMP UtilityThe parameters that should be used when running the DUMP utility on a
TLZ06 tape drive in compressed and noncompressed mode are as follows:Noncompressed Mode:

density = 61000 effective tape length (with 90 meter tape) = 57440Example:
dump Odsf 61000 57440/dev/rmt?1/dev/rrz0gCompressed Mode:

density = 61000 effective tape length (with 90 meter tape) = 57440 compression
(which, for most cases is 2)Example:
dump Odsf 61000 114880/dev/rmt?h/dev/rrz0g

Alex,

Do you know if the BA353 StorageWorks model of either the DEC TLZ06 or
TLZ07 can be adapted to fit into any other type of external enclosure?
Can the drive be removed from the StorageWorks bracket or is the drive
faceplate integrated with the bracket? Reason I am is asking is that I
have seen several BA353 StorageWorks enclosures up for sale that have a
drive included, because of existing space issues on and around my desk I
was thinking of pulling the drive and installing it into a smaller single
bay enclosure.

Thanks again... - Jim

I'm sure it would work in any StorageWorks unit supporting that size SBB's
(Storage Building Blocks), the BA353 (often referred to as a Pizza Box) is
pretty much the smallest external unit you will that supports them. Most
others such as the BA356, BA350, BA346, et al are much larger.

The only other unit that is perhaps smaller than the BA353 is the BA362
(Height 10.5", Width 7", Depth 12.67"), which supports 2 SBB's rather than 3
in the BA353.

I have over the years, removed many disc drives from their SBB's, and
subsequent installed them inside various VAXen and Alpha's, that procedure
has always been successful.

I have not however done this with a SBB mounted TLZ06/TLZ07, but it should
be possible, although you would need to pay specific attention to
connectors, termination, type of SCSI controller in your target hardware
(single ended , differential, fast, wide, narrow, ultra) etc etc
