Data security
Environment
Components connected to the Library can interfere with its function. Being a data-
handling device, a functional error may lead to data loss. The Library environment
consists of the place of location, the mains power provided, the host computer and
cables.
· The place of location must be dust free and meet the requirements of
temperature and humidity mentioned in the technical specification of the unit.
· Mains power must be stable in the range mentioned in the technical
specification of the unit. The electrical grounding must meet the regulations of
your county.
· the host computer must provide the appropriate interface for the Library. The
physical interface of the library is TCP/IP (RJ45) or TCP/IP (RJ45) and SAS
(SFF-8088 mini-SAS).
For direct attached systems the host computer must be equipped with a SAS Host Bus
Adapter (HBA):
For PCI-E systems: LSI SAS 3801e
For PCI-X systems: LSI SAS 3801x
The host computer must meet the requirements of the operation system it runs, its
Library control software and all driver applications both base upon.
Further it must provide the data transfer capacity for the Library drives.
· All cables used for the Library and the host PC must be state of the art.
For reliable usage you must also keep to the following rules.
0SU('AX_!
Avoid connecting the Library to a different mains power circuit than the host PC.
Potential differences and interference can reduce software stability and data security.
CAUTION:
Never plug cables onor off a running system.
Connecting or disconnecting power cables during operation results in crashing software.
Changes to data cable connections in a running system can further damage the Library
or host PC data interfaces.

!

Media
It is strongly recommended to use media specified in the media compatibility list of the
drive manufacturer. If unsure which drives are equipped in your Library, you can read
out the drive information by your host computers operation system tools.
For the most current information regarding media compatibility, reliability and pricing
please contact your HIT sales partner or the HIT office in your country.
Maintenance
HIT libraries are designed for use in office environments without excessive dust. In
such environments HIT libraries have no need for scheduled maintenance. For setups
under deviating conditions and recommended measures please contact your HIT office.
Unit safety requirement
Transportation
CAUTION:
Whenever the unit has to be transported, the magazines must be removed. Leaving the
magazine inside the Library during transport could lead to displaced slots, which can
block sensors.
If the unit was transported with mounted magazine(s) anyway, you should check all
slots before you start up.
See also chapter!“Magazine!installation”.!

Power cable connection
WARNING:
· Make sure, the unit is switched off at its main power switch near the built
in power plug (not just the standby switch on the front panel).
· To prevent a diversion ofpotentials, the unit should be connected to the
same power circuit as the host PC.
!!
If the Library is connected to a different power circuit with different electrical ground
potential, an equalizing current can flow trough your data cable. Interface devices can
be damaged in the host PC and the Library. If the potential difference has alternating or
high frequency elements, the data transfer can be affected, resulting in unstable
operation.
Data cable connection
WARNING:
Data cables should never be connected to working devices. There is an increased risk
to damage one or both interfaces at the end of the connection cable, if the unit is
powered on.

Type of unit
General
All NETZON libraries are standard SCSI media changer devices.
The SCSI standard describes a set of standardized elements and commands for the
operation of changer units.
The mechanical main features are the
· picker system: the mechanism for handling 120mm optical media
· the 35-slot magazine, which allows bulk handling of media
inside and outside of the Library.
Technology
NETZON libraries use point-to-point SATA/SAS cabling with an external or internal host
PC. Libraries provide a combined data transfer rate of the drives installed.
NETZON libraries transfer host PC commands to the robotics controller by iSCSI. This
means, the SCSI commands for the robotics and its answers are encapsulated in
TCP/IP packets and sent on a separate LAN connection.
Naming
The HMS media changer type designation consists of the form factor of
the device and the maximum number of media it can handle.
The total media number is a multiple of the slot number of a single magazine.

Operation principles
SCSI elements
Netzon HMS media changers comply with the SCSI standard. The SCSI standard
describes the standard elements of a media changer:
SCSI standard element
Library element
storage elements
magazine slots
transport elements
lift and picker
import/export element
mail slot
data transfer elements
optical drives for 120mm media
A standard SCSI media changer like the NETZON libraries has two or more status
options for every element. The most important ones in normal operation are full and
empty - each element position in the Library may or may not hold a medium. Thus
certain moves inside the Library are allowed: the content of a full element can be taken
to an empty element.
The changers internal control provides the basic logic to handle media, it can prevent
wrong moves instructed by the host PC and quit them with an error message. It cannot
correct them or initialize own moves apart from very few exceptions.
Command transfer
Robotics: command transfer through LAN interface
Drives: command and data transfer through S-ATA/SAS interface
Compared with the data transfer rate from/to the drives during read/write, minimal
transfer capacities are used for the control of the media changer.

!
13 of 54!
Element status
0SU('AX_!
This chapter is important to understand the function of your media changer system.
There are three element status situations to consider:
· the physical media status in the Library
· the media status in the memory of the Library controller
· the media status in the memory of the host computer software
Your system runs flawlessly as long as these three statuses are synchronous. As soon
as there any differences, inevitably trouble will occur.
A library must rescan each of its elements after each uncontrolled condition.
Uncontrolled conditions are:
· uncontrolled power off
· removed magazine
· manual interaction
Recovery from an uncontrolled state requires a full library rescan initialized by the PC
software. The rescan will synchronizes both, the library and the host PC software
memory. It is strongly recommended not to cancel such an element rescan.
Importing/exporting media
XA('0F_!
During full operation media added to or removed from the library should utilize the mail
slot. The mail slot has sensors to recognize the presence of a medium. It communicates
with Library controller the medium status and keeps the element status of the Library
controller memory current.
libraries have additional sensors for the magazinesand the front door to
allow a managed magazine import/export. If the door is opened, the lift will move the
picker mechanism to its home position immediately. On multi magazine Libraries the
exchange of multiple magazines at one time is supported. After inserting a magazine
again and closing the door a rescan of the affected magazine(s) will be performed.
Libraries are operational with partial population of magazines
Drives, Data transfer elements
A major advantage of media changers is the wide range of supported
drive types. libraries must be operated only with drives certified by
Netzon. For a complete list of certified drives and compatible media please contact your

!
14 of 54!
HIT office.
On customers demandnew drives can be certified. HIT can adopt most standard form
factor PC drives to their media changers. The drives must meet quality requirements
regarding tray construction, interface type and reliability.
!
XA('0F_!
Application range
There are several main purposes for a HIT media changer system; the usable features
depend largely on the library management software.
The most important are:
- Support of secure long-term data storage on industry standard media written in
standard UDF file format utilizing standard optical drives.
- Network based archiving and file sharing
- direct access to data stored on 120mm media
- support of offline data storage in 35 slot media magazines with RFID identifier

!
15 of 54!
Magazine
The magazine is a central elementof HIT libraries; it integrates 35 slots of the library.
Mounted in the library it providesdirect media access for the media changer mechanism.
It can be locked andremoved from the library as a whole, providing safe storage of
media in unchanged sort order. Having a RFID labelfor immediate re-recognition in the
library, the HIT magazine can expand the storage capacity of a library system by large
amounts of database managed offline media.
Picker mechanism
The HIT media changer mechanism is structured in three basic functional units:
- the lift mechanism for vertical transport in the 1035/2105 type libraries and for
vertical and horizontal transport in the 3xxx type libraries.
- the picker mechanism for opening the magazine slot and positioning the catch
mechanism.
- the catch mechanism, that can hold and release media for transportation.
The picker mechanism is the central element of the media transport, connecting the
libraries storage-, catch- and lift elements. During vertical lift movements the tab for the
horizontal slot movement travels behind the individual slot tabs. According to software
commands it can be positioned at each magazine slot and pull it out. After media
exchange a slot is pushed back into the magazine. The tab for the horizontal movement

!

then is back in a position to allow vertical movement of the lift.
The picture shows a magazine slot partly pulled out by the picker.
With the slot open, the whole Picker unit including the catch mechanism is lowered,
diving the catcher into the open medium center.
The left picture shows the picker attached to the horizontal and vertical actuators, the

Host software
A HIT library is operated by SCSI commands. Library management software presents a
user interface for library administration and a client interface for file access.
The library management software defines the usable features of a library. There are 2
concepts for presenting the library to a user:
- File system presentation
The library is presented as a drive letter or network share. Media or groups of media
are presented as data volumes with transparent read/write access.
- Tiered file system (HSM type)
The library is part of a tiered file system structure with rule based file migration
between storage devices. The client will have no actual view of the library the library
is rather presented as a transparent extension of a primary storage device.
Drive configuration
Your HIT library is shipped to order with variousoptical drives.
The only inevitable feature of these drives is the 120mm media form factor and the
necessity of a tray that must comply with the usage of the HIT catch mechanism.
HIT libraries ship with certified drives only. For integration of specific drives please
contact your HIT sales office. HIT will provide a list of certified drives on request.
The type and number of drives in a library should be defined according to their purpose,
the libraries user access frequency, the designated data throughput and its limitations by
the host PC.
HIT libraries are available with the following drive configurations:
- HMS1035: 1 or 2 drives
- HMS2105: 2 or 4 drives
- HMS3350: 2, 4 or 6 drives, 8 drive option for units without NAS or printer
- HMS3560: 2, 4, 6 or 8 drives
