The DELL™ PowerVault™ 110T LTO drive combines capacity and performance
with reliability and low cost of ownership, making it the ideal choice for network
backup. With a combination of data compression and compaction, the DELL PowerVault
110T LTO drive offers a formatted cartridge capacity of 100GB (200GB assuming
a 2:1 compression ratio) and a sustained user data transfer rate of 15MB/s (up
to 30MB/s with 2:1 compression). The capacity you realize in practice depends
on the data set, which affects the actual compression ratio.
The DELL PowerVault 110T LTO drive is a 5.25-inch, full-height form factor,
and uses 200GB tape cartridges (assuming 2:1 compression), as specified in the
LTO ULTRIUM standard. These are single-reel cartridges that match your drive's
format and are optimized for high capacity, throughput and reliability.
* Assumes 2:1 compression ratio. The capacity you realize in practice depends
on the data set, which affects the actual compression ratio.
SCSI Bus Interface
DELL PowerVault 110T LTO drives
are Ultra2 wide SCSI devices designed to operate on a low voltage differential
SCSI bus (LVD) with a burst transfer rate of 80 MB/sec. Do not use the drive
on a single-ended SCSI bus as performance is restricted. Do not use on the same
bus as other single-ended devices as this will switch the LVD host adapter into
single-ended mode and restrict performance.
Your computer must have a properly installed and configured
SCSI host adapter or a SCSI controller on the motherboard (SCSI-2 or SCSI-3
compliant) with driver software that supports the PowerVault 110T LTO drive.
We recommend that a dedicated host bus adapter is used for the tape drive.Check
the server documentation for the specification of any built-in SCSI channels.
Do not connect to a RAID controller channel; these are for disk drives only.
Consult your supplier for details.
You need backup software that supports the DELL PowerVault
110T LTO drive. As a general rule, native backup applications (such as NTBackup
and tar) do not provide the required data streaming rate to get the full performance
of your DELL PowerVault 110T LTO drive. We recommend using a backup application,
which provides better memory management as well as other useful features, such
as TapeAlert. Computer Associates, Veritas, Legato and Tivoli all provide suitable
products that have been tested with DELL PowerVault 110T LTO drives, as listed
below:
Computer Associates™
ArcServe™ for Windows NT, Windows 2000, Novell® NetWare®
VERITAS®
Backup Exec™ for Windows NT, Windows 2000, Novell® NetWare®
Netbackup for Windows NT
Legato™
Networker
Tivoli™
ADSM for Windows NT
Suitable backup applications will include driver software
that establishes the interface between the tape drive and the software. Applications
usually recognize tape drives by their manufacturers' internal part number rather
than their model number, so check the table below for the appropriate reference.

The front panel (See Figure 1) of your DELL
PowerVault 110T LTO drive has four lights (LEDs) as shown below.
Figure 2.Ready LED (green, top light)
This LED (see Figure 2) is the Power On/Activity
LED.
On: the drive is ready for use. It is powered
up but not doing anything. Off: the drive power is off or there was a failure during self-test. Flashing:the drive is busy. For example: it is carrying out Write,
Read, Self Test or firmware download.
Figure 3.Drive Error LED (amber, second
light)
This LED (see Figure 3) is to indicate a Drive
Error.
Off: no fault has been detected. Flashing: the drive has suffered an unrecoverable hardware failure.
A power cycle or a successful tape load will turn off the LED, but if the hardware
fault is still present it will come on again if the same operation is performed.
Power cycling an internal drive should be considered a last option - it is recommended
to try resetting the drive using the reset button
first.
Figure 4.Tape Error LED (amber, third
light)
This LED (see Figure 4) is to indicate a Tape Error.
Off: no fault has been detected. Flashing: the tape currently in the drive is faulty. This LED
could come on for a number of reasons, but they all relate to the tape being
in error in some way, such as unreadable cartridge memory or unsupported tape.
Do not use the cartridge; replace it. The LED will go out when a tape load is
started.
Figure 5.Use Cleaning Cartridge LED (amber,
bottom light)
This LED (see Figure 5) indicates when a cleaning
tape should be used. See also "Cleaning".
On: cleaning cartridge is being used. The Ready
light will also flash. Off: the drive does not require cleaning. Flashing: the drive needs cleaning. The light will continue to
flash if the drive is power cycled, and will only go out after a supported cleaning
tape has been used.
The rear panel (see Figure 6) of
your DELL PowerVault 110T LTO drive (external
models only) has two additional lights (LEDs) as shown below.
Figure 7.Act TERM (termination active)
This LED (see Figure 7) indicates active SCSI termination.
On: the drive enclosure is providing active termination
on the SCSI bus. Off: the drive enclosure is not providing active termination (there is
another device or terminator attached to the SCSI-OUT connector)
Figure 8.Fan/PWR Fault (fault with the
fan or power supply)
This LED (see Figure 8) indicates a fan or power
supply fault.
Off: no fault has been detected. On: a fault with the fan or power supply has been detected.
