xIBM TotalStorage IP Storage 200i Models 110 and 210 Installation Guide
Chapter 1. General Information
This chapter provides an overview of the IBM®TotalStorage™IP Storage 200i and
iSCSI clients, and lists the standard and optional features and hardware
specifications for Models 110 and 210.
IBM IP Storage 200i
The IBM TotalStorage IP Storage 200i consists of the IBM 4125 IP Storage Models
110 and 210. These models are designed for workgroups, departments, and
solution providers that have storage area network requirements across
heterogeneous Microsoft
clients). It includes preloaded code and offers virtually “Plug and Play” IP-based
storage.
Model 110 is a tower unit that requires only power and network connections for
setup. A conversion kit is available to convert Model 110 for rack mounting. The
Model 210 can be mounted in a 5U rack drawer. In addition to power and network
interfaces, the Model 210 has external SCSI connections for up to three storage
units for a total rack requirement of 14U.
For additional storage, a Model EXP (also known as a storage unit) can be
attached to the Model 210 to increase its storage capacity. Each storage unit
supports up to 14 Ultra160 SCSI hard disk drives. It delivers fast, high-volume data
transfer, retrieval, and storage functions across multiple drives.
®
Windows NT®, Windows®2000, and Linux clients (iSCSI
iSCSI clients
The iSCSI clients allow Microsoft Windows NT, Windows 2000, and Linux
computers to access storage over an IP network. The iSCSI client, as an iSCSI
initiator, issues SCSI commands to the IP Storage 200i according to the
IETF-defined protocol for IP storage.
When the iSCSI client is successfully connected to the IP Storage 200i, any disks
assigned to the iSCSI client appear as a physical disk. Operations normally
performed on a physical SCSI disk can be performed on an iSCSI disk.
Note: You cannot boot from an iSCSI disk; instead, the iSCSI disk is used for
storage after the computer is booted.
You can download the iSCSI client code from the following Web site:
Note: You cannot mix drives
with different sizes in the
Models 110 and 210. You
can, however, mix drives with
different sizes in the storage
unit Model EXP.

Chapter 2. Installation procedures29
Service Ethernet port
Your appliance has an integrated 10/100 Ethernet controller. This controller provides
an interface for connecting to 10-Mbps or 100-Mbps networks and provides
full-duplex (FDX) capability, which enables simultaneous transmission and reception
of data on the Ethernet local area network (LAN).
Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the
network be Category 5 or higher.
Configuring the Service Ethernet controller: When you connect your appliance
to the network, the Service Ethernet controller automatically detects the
data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the Service
Ethernet controller to operate at the appropriate rate. That is, the Ethernet controller
will adjust to the network data rate, whether the data rate is standard Ethernet
(10BASE-T), Fast Ethernet (100BASE-TX), half-duplex (HDX), or full-duplex (FDX).
The controller supports HDX and FDX modes at both speeds.
The Service Ethernet controller is a PCI Plug and Play device. You do not need to
set any jumpers or configure the controller for your operating system before you
use the Service Ethernet controller.
Failover for redundant Ethernet: The Serivice Ethernet adapter does not support
a failover function.

General safety
Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the machines during and after
maintenance.
v When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
Appendix C. Safety notices51
3. Use a slow lifting force. Never move suddenly or twist when you attempt to
lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes
the strain from the muscles in your back. Do not attempt to lift any objects
that weigh more than 16 kg (35 lb.) or objects that you think are too heavy for
you.
v Do not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
v Before you start the machine, ensure that other service representatives and the
customer’s personnel are not in a hazardous position.
v Place removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
v Keep your tool case away from walk areas so that other people will not trip over
it.
v Do not wear loose clothing that can be trapped in the moving parts of a machine.
Ensure that your sleeves are fastened or rolled up above your elbows. If your
hair is long, fasten it.
v Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Remember: Metal objects are good electrical conductors.
v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,
attaching springs, using solvents, or working in any other conditions that might be
hazardous to your eyes.
v After service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
v Reinstall all covers correctly before returning the machine to the customer.
Electrical safety
Caution:
Electrical current from power, telephone, and communication cables can be
hazardous. To avoid personal injury or equipment damage, disconnect the
attached power cords, telecommunication systems, networks, and modems
before you open the appliance covers, unless instructed otherwise in the
installation and configuration procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have
handles covered with a soft material that does not insulate you when
working with live electrical currents.
Many customers have, near their equipment, rubber floor mats that
contain small conductive fibers to decrease electrostatic discharges. Do
not use this type of mat to protect yourself from electrical shock.
52IBM TotalStorage IP Storage 200i Models 110 and 210 Installation Guide
v Find the room emergency power-off (EPO) switch, disconnecting switch, or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
v Before you start to work on the machine, unplug the power cord. If you cannot
unplug it, ask the customer to power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
v If you need to work on a machine that has exposed electrical circuits, observe
the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if
necessary.
– Use only one hand when working with powered-on electrical equipment; keep
the other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By
observing the above rule, you may prevent a current from passing through
your body.
– When using testers, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you
from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages;
these instructions are in the safety sections of maintenance information. Use
extreme care when measuring high voltages.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition.
v Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from a circuit. First, check that
it has been powered-off.
v Always look carefully for possible hazards in your work area. Examples of these
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.
v Do not touch live electrical circuits with the reflective surface of a plastic dental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
v Do not service the following parts with the power on when they are removed from
their normal operating places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
– Similar units
This practice ensures correct grounding of the units.
v If an electrical accident occurs:
– Use caution; do not become a victim yourself.
Appendix C. Safety notices53
– Switch off power.
– Send another person to get medical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe
conditions on these products. Each machine, as it was designed and built, had
required safety items installed to protect users and service personnel from injury.
This guide addresses only those items. However, good judgment should be used to
identify potential safety hazards due to attachment of non-IBM features or options
not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard could be and whether you can continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
v Electrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock).
v Explosive hazards, such as a damaged CRT face or bulging capacitor
v Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks
with the power off, and the power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Power-off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external ground
pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts
listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur when
there is a difference in charge between objects. Protect against ESD damage by
equalizing the charge so that the machine, the part, the work mat, and the person
handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted
here.
54IBM TotalStorage IP Storage 200i Models 110 and 210 Installation Guide
2. Make sure that the ESD protective devices you use have been certified (ISO
9000) as fully effective.
When handling ESD-sensitive parts:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to eliminate static on your body.
v Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
v Use the black side of a grounded work mat to provide a static-free work surface.
The mat is especially useful when handling ESD-sensitive devices.
v Select a grounding system, such as those listed below, to provide protection that
meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– Use an ESD common ground or reference point when working on a
double-insulated or battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the AC plug on AC-operated computers.
Grounding (earthing) requirements
Electrical grounding (earthing) of the computer is required for operator safety and
correct system function. Proper grounding of the electrical outlet can be verified by
a certified electrician.

Numerics
10BASE2. The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using RG 58 A/U and RG
58 C/U coaxial cable and BNC connectors. 10BASE2 is sometimes called thin Ethernet or thinnet.
10BASE5. The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using a 50-ohm coaxial
cable with Type N connectors over a distance of up to 500 m (1640 ft) without using repeaters. 10BASE5 is
sometimes called thick Ethernet or thicknet.
10BASE-FL. The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using optical fiber.
10BASE-T. The IEEE 802.3 Ethernet standard that supports a transmission rate of 10 Mbps using two twisted-pair
wires (Category 3 telephone wiring). 10BASE-T is the most widely deployed 10-Mbps Ethernet transmission protocol in
use today.

wires (Category 5 telephone wiring).
A
access control. In computer security, the process of ensuring that the resources of a computer system can be
accessed only by authorized users in authorized ways.
access control list (ACL). (1) In computer security, a collection of all access rights for one object. (2) In computer
security, a list associated with an object that identifies all the subjects that can access the object and their access
rights; for example, a list associated with a file that identifies users who can access the file and identifies their access
rights to that file.
accessory. An IBM designation for a separately orderable part that (a) has no type number, (b) is for purchase only,
and (c) does not receive normal IBM maintenance.
active-backup. A type of bond group that provides high availability. Two or more ports are combined under a logical
bond group with one link active and the other link or links left idle. The idle links are ready to take over in the event
that the currently active link fails. See bond group.
active dispatcher node. The engine within a load-balancing group that functions as the load balancer for that group.
Because each NAS engine can have multiple physical and bonded interfaces, there can be more than one
load-balancing engine per set of engines. Each load-balancing engine acts as an active backup for another
load-balancing engine within that set. Alternatively, there can be only one active load-balancing engine per set of
engines and one passive backup (standby) load-balancing engine.
actual data transfer rate. The average number of bits, characters, or blocks per unit of time transferred from a data
source and received by a data sink.
adapter address. The hexadecimal digits that identify an adapter.
adaptive cut-through switching. A mode of operation for LAN switches in which they will automatically alternate
between cut-through switching and store-and-forward switching depending on user-configurable, per port, error-rate
thresholds.
advertise. To pass routing reachability information along from one router to another.
all-routes broadcast frame. A frame that has bits in the routing information field set to indicate that the frame is to
be sent to all LAN segments in the network (across all bridges, even if multiple paths allow multiple copies of the
frame to arrive at some LAN segments). The destination address is not examined and plays no role in bridge routing.
all-stations broadcast frame. A frame whose destination address bits are set to all ones. All stations on any LAN
segment on which the frame appears will copy it. The routing information, not the destination address, determines
which LAN segments the frame appears on. All-stations broadcasting is independent of all-routes broadcasting; the
two can be done simultaneously or one at a time.
alternate adapter. In a personal computer that is used on a LAN and that supports installation of two network
adapters, the adapter that uses alternate (not standard or default) mapping between adapter-shared RAM, adapter
ROM, and designated computer memory segments. The alternate adapter is usually designated as adapter 1 in
configuration parameters. Contrast with primary adapter.
alternate memory mapping. The mapping between adapter-shared RAM, adapter ROM, and the designated
computer memory segments for an alternate network adapter.
ASM (see advanced system management).
assigned disk. A disk that is mapped to a logical drive.
asynchronous. A class of data transmission service whereby all requests for service contend for a pool of
dynamically allocated ring bandwidth and response time.
asynchronous data transfer. A physical transfer of data to or from a device that occurs without a regular or
predictable time relationship following execution of an I/O request. Contrast with synchronous data transfer.
asynchronous transfer mode (ATM). A transfer mode in which the information is organized into cells; it is
asynchronous in the sense that the recurrence of cells containing information from an individual user is not necessarily
periodic. ATM is specified in international standards such as ATM Forum UNI 3.1.
asynchronous transmission. A method of transmission in which the time intervals between characters do not have
to be equal. Start and stop bits are added to coordinate the transfer of characters.
ATM (see asynchronous transfer mode).
attach. To make a device a part of a network logically. Not to be confused with connect, which implies physically
connecting a device to a network. Contrast with connect.
attachment. A port or a pair of ports, optionally including an associated optical bypass, that are managed as a
functional unit. A dual attachment includes two ports: a port A, and a port B. A single attachment includes a Port S.
attachment feature. (1) The circuitry by which some host processors or controllers are connected to a LAN access
unit or connection point. (2) A feature that can be added to enhance the capability, storage capacity, or performance of
a product, but is not essential for its basic work; for example, an adapter that allows a device to attach to a network.
attachment unit interface (AUI). Also known as thick Ethernet, thicknet or 10BASE5. This type of Ethernet
connector has a 15-pin D type connector.
58IBM TotalStorage IP Storage 200i Models 110 and 210 Installation Guide
attention (ATTN). An occurrence external to an operation that could cause an interruption of the operation.
AUI (see attachment unit interface).
authentication. In computer security, verification of the identity of a user or the user’s eligibility to access an object.
auto-removal. The removal of a device from data-passing activity without human intervention. This action is
accomplished by the adapter in the device, and can be initiated by a network management program.
B

coaxial cables, by matching the electrical characteristics of the cables.
bandwidth aggregation. The ability to establish more than one communication channel per connection.
bandwidth augmentation. The ability to add another communication channel to an already existing communication
channel.
bandwidth-distance product. The parameter specified for bulk fiber that defines the distance that a signal at a
defined frequency can be transmitted with a specified loss, usually half the power at zero frequency. Use of a fiber
with a bandwidth-distance product of 500 MHz-km would support 250 MHz for a distance of 2 km.
baseband LAN. A local area network in which data are encoded and transmitted without modulation of a carrier (T).
Basic Input/Output System. The personal computer code that controls basic hardware operations, such as
interactions with diskette drives, hard disk drives, and the keyboard.
baud. (1) A unit of signaling speed equal to the number of discrete conditions or signal events per second; for
example, one baud equals one-half dot cycle per second in Morse code, one bit per second in a train of binary
signals, and one 3-bit value per second in a train of signals each of which can assume one of eight different states
(A). Contrast with bits per second. (2) In asynchronous transmission, the unit of modulation rate corresponding to one
unit interval per second; that is, if the duration of the unit interval is 20 milliseconds, the modulation rate is 50 baud.
BIOS (see Basic Input/Output System).
bit-time. (1) The time required to transmit 1 bit on the network. For example, the IBM PC Network bit-time equals
500 nanoseconds (ns). (2) The reciprocal of the line data rate (or network data transfer rate).
bits per second (bps). The rate at which bits are transmitted per second. Contrast with baud.
block delay time. The time delay permitted for received frames to be assembled into blocks for retransmission.
bond group. A logical collection of two or more physical ports (on a per engine basis only) that becomes one
interface on the network. You can create two kinds of bond groups in the NAS appliance: aggregated links (see link
aggregration) and active-backup.
bonded interface (see bond group).
bonding. The act of combining two or more physical ports to create one logical network interface with one
associated IP address. Bonding can improve performance by either increasing bandwidth (see link aggregation) or
providing port backup (see active-backup).
bootstrap. (1) A sequence of instructions whose execution causes additional instructions to be loaded and executed
until the complete computer program is in storage (T). (2) A technique or device designed to bring itself into a desired
state by means of its own action, for example, a machine routine whose first few instructions are sufficient to bring the
rest of itself into the computer from an input device (A).
bps (see bits per second).
broadcast frame. A frame that is simultaneously transmitted to more than one destination. A broadcast frame is
forwarded by all bridges, unless otherwise restricted.
IBM Glossary of Storage Networking Terms59
broadcast topology. A network topology in which all attaching devices are capable of receiving a signal transmitted
by any other attaching device on the network.
buffer storage. (1) A special-purpose storage or storage area allowing, through temporary storage, the data transfer
between two functional units having different transfer characteristics. A buffer storage is used between

store-and-forward. A mode of operation for a LAN switch in which it completely checks every frame before
forwarding, so customers can use the switch to isolate erroneous frames generated on one segment so they do not
traverse the switch onto another segment.
STP (see shielded twisted pair).
SVN (see switched virtual network).
switched LAN. A LAN that has a dedicated connection for each user whereby the full bandwidth is available to the
workstation.
switched virtual networks (SVN). A comprehensive approach for building and managing switched-based networks.
It combines the virtues of LAN switching, bridging, routing, ATM switching and other switched services.
synchronous data transfer. A physical transfer of data to or from a device that has a predictable time relationship
with the execution of an I/O request.
synchronous transmission. A method of transmission in which characters are synchronized by the transmission of
initial sync characters and a common clock signal.
T
tape device. A collection of tape units that come from one model type and serial number (such as all the LUNs of a
tape library).
tape unit. A tape drive or a robotics controller that is visible over a storage network. A tape unit is a member of a
single storage network (of 1 to n fabrics), but can have 1 to n equivalent paths.
target. A collection of logical units that are directly addressable on the network. The target corresponds to the server
in a client-server model.
TCP (see Transmission Control Protocol).
TCP/IP (see Transmission Control Protocol/Internet Protocol).
Telnet. In the Internet suite of protocols, a protocol that provides remote terminal connection service. It allows users
of one host to log on to a remote host and interact as directly attached terminal users of that host.
IBM Glossary of Storage Networking Terms71
timeout. A time interval that is allotted for certain operations to occur, for example, a response to polling or
addressing before system operation is interrupted and must be restarted.
Tivoli Storage Manager (TSM). A client/server product that provides storage management and data access services
in a heterogeneous environment.
Transmission Control Protocol (TCP). In TCP/IP, a host-to-host protocol that provides transmission in an internet
environment. TCP assumes Internet Protocol (IP) is the underlying protocol.
Transmission Control Protocol/Internet Protocol (TCP/IP). The Transmission Control Protocol and the Internet
Protocol, which together provide reliable end-to-end connections between applications over interconnected networks of
different types.
True Image data view. A data view that allows the file to be restored in the event of accidental deletion. It consists
of ‘point-in-time’ images that provide a near-instant virtual copy of an entire storage volume.
TSM (see Tivoli Storage Manager).
twinaxial cable. A three-conductor cable with the two inner conductors serving to carry the signal energy, and the
outer conductor serving as ground. The three conductors are insulated from each other.
U
universal serial bus (USB). A serial interface standard for telephony and multimedia connections to personal
computers.
unshielded twisted pair (UTP). A cable medium with one or more pairs of twisted insulated copper conductors
bound in a single plastic sheath.
USB (see universal serial bus).
V
VLAN (see virtual local area network).
VLU. Volume logical unit.
VLUN (see virtual logical unit).
virtual connection. A connection set up between two points that appears to the user to be available as a dedicated
connection. This phantom connection can be maintained indefinitely or can be ended at will. The three states of a
virtual connection are up, down or suspended.
virtual local area network (VLAN). A logical association of switch ports based upon a set of rules or criteria such as
MAC addresses, protocols, network address, or multicast address. This permits resegmentation of the LAN without
requiring physical rearrangement.
virtual logical unit (VLUN). A subset of a logical drive.
virtual port. Logical construct that corresponds to a logical adapter for a switched network port. A virtual port
organizes outgoing switched logical links by specifying incoming call acceptance criteria, by dynamically building and
relating logical adapters with selected hardware adapter ports, and by specifying adapter-related data link control
(DLC) profiles for use with those logical adapters.
VNI. Virtual network interface.
volume. (1) Unit of storage on disk, tape, or other data recording media. (2) A logical disk visible to the appliance
over a storage network. A member of a single storage network of 1 to n fabrics. It can have 1 to n path groups of 1 to
n equivalent paths.

W
Windows Internet Name Service (WINS). Program that provides a distributed database for registering and querying
dynamic NetBIOS names to IP address mapping in a routed network environment.*
WINS (see Windows Internet Naming Service).
Windows networking. Networking file-system protocol for the Windows operating system.
X
Xmodem. A public-domain asynchronous data link control (DLC) protocol that provides packet numbering and
checksum error control for the transfer of binary files.
