Chapter 1. Introduction
Chapter 1. INTRODUCTION
This chapter provides a brief introduction of Array Definition and RAID concept.
11..11 A
Arrrraayy D
Deeffiinniittiioonn
1.1.1 Raid Set
A Raid Set is a group of disks containing one or more volume sets. It has the
following features in the RAID subsystem:
1. Up to sixteen Raid Sets are supported per RAID subsystem controller.
2. From one to twelve/sixteen/twenty four (depend on Model) drives can be
included in an individual Raid Set.
3. It is impossible to have multiple Raid Sets on the same disks.
A Volume Set must be created either on an existing raid set or on a group of
available individual disks (disks that are not yet a part of a raid set). If there are
pre-existing raid sets with available capacity and enough disks for specified
RAID level desired, then the volume set will be created in the existing raid set of
the user’s choice. If physical disks of different capacity are grouped together in a
raid set, then the capacity of the smallest disk will become the effective capacity
of all the disks in the raid set.
1.1.2 Volume Set
A Volume Set is seen by the host system as a single logical device. It is
organized in a RAID level with one or more physical disks. RAID level refers to
the level of data performance and protection of a Volume Set. A Volume Set
capacity can consume all or a portion of the disk capacity available in a Raid Set.
Multiple Volume Sets can exist on a group of disks in a Raid Set. Additional
Volume Sets created in a specified Raid Set will reside on all the physical disks
in the Raid Set. Thus each Volume Set on the Raid Set will have its data spread
evenly across all the disks in the Raid Set.
1. Volume Sets of different RAID levels may coexist on the same Raid Set.
2. The maximum addressable size of a single volume set can be exceeded than
2 TB (64-bit LBA, firmware define support up to 512TB, for Windows block
size set to 4KB can support up to 16TB).
3. Up to sixteen volume sets can be created in a raid set.
In the illustration below, Volume 1 can be assigned a RAID 5 level of
operation while Volume 0 might be assigned a RAID 0+1 level of operation.

1.1.3 Instant Availability/Background Initialization
RAID 0 and RAID 1 volume set can be used immediately after the creation. But
the RAID 3, 5, 6, and X0 volume sets must be initialized to generate the parity. In
the Normal Initialization, the initialization proceeds as a background task, the
volume set is fully accessible for system reads and writes. The operating
system can instantly access to the newly created arrays without requiring a
reboot and waiting the initialization complete. Furthermore, the RAID volume
set is also protected against a single disk failure while initializing. In Fast
initialization, the initialization process must be completed before the volume set
is ready for system accesses.
1.1.4 Array Roaming
The RAID subsystem stores configuration information both in NVRAM and on
the disk drives. This way it can protect the configuration settings in case of a
disk drive or controller failure. Array roaming allows the administrators the ability
to move a completely raid set to another system without losing RAID
configuration and data on that raid set. If a server fails to work, the raid set disk
drives can be moved to another server and inserted in any order.
1.1.5 Online Capacity Expansion
Online Capacity Expansion makes it possible to add one or more physical drives
to a volume set, while the server is in operation, eliminating the need to store
and restore after reconfiguring the raid set. When disks are added to a raid set,
unused capacity is added to the end of the raid set. Data on the existing volume
sets residing on that raid set is redistributed evenly across all the disks. A
contiguous block of unused capacity is made available on the raid set. The
unused capacity can create additional volume set. The expansion process is
illustrated in the following figure.
2
Chapter 1. Introduction
Before Array Expansion
Free Space = 40GB
Volume 1 = 40GB (D: )
Volume 0 = 40GB (C: )
Disk0 40GB
Disk1 40GB
Disk2 40GB
Array-A 120GB
The RAID subsystem controller redistributes the original volume set over the
original and newly added disks, using the same fault-tolerance configuration.
The unused capacity on the expanded raid set can then be used to create an
additional volume set, with a different fault tolerance setting if user needs to
change.
After Array Expansion (Adding One Disk)
Free Space = 80GB
Volume 1 = 40GB (D: )
Volume 0 = 40GB (C: )
Disk0 40GB
Disk1 40GB
Disk2 40GB
Disk3 40GB
Array-A 160GB
1.1.6 Online RAID Level and Stripe Size Migration
User can migrate both the RAID level and stripe size of an existing volume set,
while the server is online and the volume set is in use. Online RAID level/stripe
size migration can prove helpful during performance tuning activities as well as
in the event where those additional physical disks are added to the RAID
subsystem. Before the invention of RAID level and stripe size migration,
changing the RAID level and stripe size of a RAID system meant backing up all
data in the disk array, re-creating disk array configuration with new RAID level
and stripe size, and then restoring data back into RAID system. For example, in
a system using two drives in RAID level 1, you could add capacity and retain
fault tolerance by adding one drive. With the addition of third disk, you have the
option of adding this disk to your existing RAID logical drive and migrating from
RAID level 1 to 5. The result would be parity fault tolerance and double the
available capacity without taking the system off.
1.1.7 Hot Spares
A hot spare drive is an unused online available drive, which is prepared for
3
Software Operation Manual
replacing the failure disk drive. In a RAID level 1, 1E, 3, 5, 6, X0 RAID set, any
unused online available drive installed but not belonging to a RAID set can
define as a hot spare drive. Hot spares permit you to replace failed drives
without powering down the system. When RAID subsystem detects a SAS (or
SATA) drive failure, the system will automatically and transparently rebuild using
the hot spare drives. The raid set will be reconfigured and rebuilt in the
background, while the RAID subsystem continues to handle system request.
During the automatic rebuild process, system activity will continue as normal,
however, the system performance and fault tolerance will be affected.
The hot spare must have at least the same capacity as the
drive it replaces.
1.1.8 Hot-Swap Disk Drive Support
The RAID subsystem is built with the protection circuit to support the
replacement of SAS (or SATA) hard disk drives without having to shut down or
reboot the system. The removable hard drive tray can deliver “hot swappable”,
fault-tolerant RAID solutions at prices much less than the cost of conventional
SCSI hard disk RAID subsystems. We provide this feature for subsystems to
provide the advanced fault tolerant RAID protection and “online” drive
replacement.
1.1.9 Hot-Swap Disk Rebuild
A Hot-Swap function can be used to rebuild disk drives in arrays with data
redundancy such as RAID level 1, 1E, 3, 5, 6, and X0. If a hot spare is not
available, the failed disk drive must be replaced with a new disk drive so that the
data on the failed drive can be rebuilt. If a hot spare is available, the rebuild
starts automatically when a drive fails. The RAID subsystem automatically and
transparently rebuilds failed drives in the background with user-definable
rebuild rates. The RAID subsystem will automatically restart the system and the
rebuild if the system is shut down or powered off abnormally during a
reconstruction procedure condition. When a disk is Hot Swap, although the
system is functionally operational, the system may no longer be fault tolerant.
Fault tolerance will be lost until the removed drive is replaced and the rebuild
operation is completed.

RAID is an acronym for Redundant Array of Independent Disks. It is an array of
multiple independent hard disk drives that provide high performance and fault
tolerance. The RAID subsystem controller implements several levels of the
Berkeley RAID technology. An appropriate RAID level is selected when the
volume sets are defined or created. This decision is based on disk capacity,
data availability (fault tolerance or redundancy), and disk performance. The
following are the RAID levels which are supported in the RAID subsystem.
The RAID subsystem controller makes the RAID implementation and the disks’
physical configuration transparent to the host operating system. This means
that the host operating system drivers and software utilities are not affected,
regardless of the RAID level selected. Correct installation of the disk array and
the controller requires a proper understanding of RAID technology and the
concepts.
1.2.1 RAID 0
RAID 0, also referred to as striping, writes stripping of data across multiple disk
drives instead of just one disk drive. RAID 0 does not provide any data
redundancy, but does offer the best high-speed data throughput. RAID 0 breaks
up data into smaller blocks and then writes a block to each drive in the array.
Disk striping enhances performance because multiple drives are accessed
simultaneously; but the reliability of RAID Level 0 is less than any of its member
disk drives due to its lack of redundancy.
5
Software Operation Manual
1.2.2 RAID 1
RAID 1 also known as “disk mirroring”, data written to one disk drive is
simultaneously written to another disk drive. Read performance may be
enhanced if the array controller can parallel accesses both members of a
mirrored pair. During writes, there will be a minor performance penalty when
compared to writing to a single disk. If one drive fails, all data (and software
applications) are preserved on the other drive. RAID 1 offers extremely high
data reliability, but at the cost is doubling the required data storage capacity.
1.2.3 RAID 1E
RAID 1E (available only on CineRaid8 Series) has been traditionally implemented using
an even number of disks; some hybrids can use an odd number of disks as well.
Illustration is an example of a hybrid RAID 1E array comprised of five disks; A, B, C, D
and E. In this configuration, each strip is mirrored on an adjacent disk with wrap-around.
In fact this scheme - or a slightly modified version of it - is often referred to as RAID 1E
and was originally proposed by IBM. When the number of disks comprising a RAID 1E is
even, the striping pattern is identical to that of a traditional RAID 1E, with each disk being
mirrored by exactly one other unique disk. Therefore, all the characteristics for a
traditional RAID 1E apply to a RAID 1E when the latter has an even number of disks.
RAID 1E offers a little more flexibility in choosing the number of disks that can be used to
constitute an array. The number can be even or odd.
6
Chapter 1. Introduction
1.2.4 RAID 3
RAID 3 provides disk striping and complete data redundancy through a
dedicated parity drive. RAID 3 breaks up data into smaller blocks, calculates
parity by performing an exclusive-or on the blocks, and then writes the blocks to
all but one drive in the array. The parity data created during the exclusive-or is
then written to the last drive in the array. If a single drive fails, data is still
available by computing the exclusive-or of the contents in the corresponding
strips of the surviving member disk. RAID-3 is best for applications that require
very fast data- transfer rates or long data blocks
7
Software Operation Manual
1.2.5 RAID 5
RAID 5 is sometimes called striping with parity at block level. In RAID 5, the
parity information is written to all of the drives in the subsystems rather than
concentrated on a dedicated parity disk. If one drive in the system fails, the
parity information can be used to reconstruct the data from that drive. All drives
in the array system can be used to seek operation at the same time, greatly
increasing the performance of the RAID system.
1.2.6 RAID 6
A RAID 6 array is essentially an extension of a RAID 5 array with a second
independent distributed parity scheme. Data and parity are striped on a block
level across multiple array members, just like in RAID 5, and a second set of
parity is calculated and written across all the drives. As larger disk arrays are
considered, it is desirable to use stronger codes that can tolerate multiple disk
failure. When a disk fails in a parity protected disk array, recovering the contents
of the failed disk requires successful reading on the contents of all no-failed
disks. RAID 6 provides an extremely high fault tolerance, and can sustain two
simultaneous drive failures without downtime or data loss. This is a perfect
solution when data is mission-critical.
8
Chapter 1. Introduction
1.2.7 RAID X0
RAID level-X0 (available only on CineRaid8 Series) refers to RAID level- 10, 30,
50 and 60. RAID X0 is a combination of multiple RAID x volume sets with RAID
0 (striping). Striping helps to increase capacity and performance without adding
disks to each RAID x array. The operating system uses the spanned volume in
the same way as a regular volume. Up to one drive in each sub-volume (RAID 1,
3 or 5) may fail without loss of data. Up to two drives in each sub-volume (RAID
6) may fail without loss of data.
The following illustration is an example of a RAID level-X0 logical drive.
RAID level-X0 allows more physical drives in an array. The benefits of doing so
9
Software Operation Manual
are larger volume sets, increased performance, and increased reliability.
RAID level-30 50 and 60 can support up to eight sub-Volumes.
If the volume is RAID level-30, 50, or 60, you cannot change
the volume to another RAID level. If the volume is RAID
level-0, 1, 1E, 3, 5, or 6, you cannot change the volume to
RAID level-30, 50, or 60.
1.2.8 Summary of RAID Levels
RAID subsystem supports RAID Levels 0, 1, 1E, 3, 5, 6, 30, 50 and 60. The

After the hardware installation, the SAS (or SATA) disk drives installed to the
RAID must be configured and the volume set units initialized before they are
ready to use. This can be accomplished by one of the following methods:
•
Front panel touch-control keypad
•
Remote utility connected through the controller’s serial port (VT-100 or
Hyper terminal)
•
Using HTTP Proxy through the controller’s serial port to access web
browser-based RAID manager in Windows and Linux system.
•
Firmware-embedded TCP/IP & web browser-based RAID manager via the
controller’s 10/100 Ethernet LAN port.
Those user interfaces can access the built-in configuration and administration
utility that resides in the controller’s firmware. They provide complete control
and management of the controller and disk arrays, eliminating the need for
additional hardware or software.
Note
The RAID subsystem allows only one method to access menus at a
time.

The front panel keypad and liquid crystal display (LCD) is the primary user
interface for the RAID subsystem. All configuration and management of the
RAID and its properly connected disk arrays can be performed from this
interface.
The front panel keypad and LCD are connected to the RAID subsystem to
access the built-in configuration and administration utility that resides in the
controller’s firmware. Complete control and management of the array’s physical
drives and logical units can be performed from the front panel, requiring no
additional hardware or software drivers for that purpose.

Chapter 2. Configuration Methods
This Chapter provides, in quick reference form, procedures that use the built-in
LCD panel to configure and operate the controller.
A touch-control keypad and a liquid crystal display (LCD) mounted on the front
panel of the RAID subsystem is the primary operational interface and monitor
display for the disk array controller. This user interface controls all configuration
and management functions for the RAID subsystem controller and for all SAS
(or SATA) disk array subsystems to which it is properly connected.
The LCD provides a system of screens with areas for information, status
indication, or menus. The LCD screen displays up to two lines at a time of menu
items or other information.

A volume set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a Volume Set. A Volume Set capacity can consume all
or a portion of the disk capacity available in a Raid Set. Multiple Volume Sets can
exist on a group of disks in a Raid Set. Additional Volume Sets created in a specified
Raid Set will reside on all the physical disks in the Raid Set. Thus each Volume Set on
the Raid Set will have its data spread evenly across all the disks in the Raid Set.

complete the create volume set function.
3.7.3.1.1 Capacity
The maximum volume size is default in the first setting. Enter the appropriate volume
size to fit your application. The capacity can also increase or decrease by the UP and
DOWN arrow keys. Each volume set has a selected capacity which is less than or
equal to the total capacity of the raid set on which it resides.
3.7.3.1.2 Raid Level
RAID subsystem can support raid level 0, 1, 1E (0+1), 3, 5, 6, 30, 50, and 60.
3.7.3.1.3 Strip Size
This parameter sets the size of the segment written to each disk in a RAID 0, 1, 1E
(0+1), 5, 6, 50 or 60 logical drives. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32
KB, 64 KB, or 128 KB.
A larger stripe size produces better-read performance, especially if your computer
does mostly sequential reads. However, if you are sure that your computer does
random reads more often, select a small stripe size.
3.7.3.1.4 Volume Name
The default volume name will always appear as Volume Set. #. You can rename the
volume set name as long as it does not exceed the 15 characters limit.

A volume set is seen by the host system as a single logical device. It is organized in a
RAID level with one or more physical disks. RAID level refers to the level of data
performance and protection of a volume set. A volume set capacity can consume all
or a portion of the disk capacity available in a raid set. Multiple volume sets can exist
on a group of disks in a raid set. Additional volume sets created in a specified raid set
will reside on all the physical disks in the raid set. Thus each volume set on the raid
set will have its data spread evenly across all the disks in the raid set.
4.9.1 Create Volume Set
The following is the volume set features for the CineRaid SAS/SATA RAID
1. Volume sets of different RAID levels may coexist on the same raid set.
2. Up to 16 volume sets can be created in a raid set.
3. The maximum addressable size of a single volume set can be exceeded than 2 TB
(64-bit LBA, firmware define support up to 512TB, for Windows block size set to
4KB can support up to 16TB).
To create volume set from raid set system, move the cursor bar to the main menu and
click on the Create Volume Set link. The Select the Raid Set to Create on It screen

4.9.1.4 Strip Size:
This parameter sets the size of the stripe written to each disk in a RAID 0, 1, 1E (0+1),
5, 6, 50 or 60 logical drives. You can set the stripe size to 4 KB, 8 KB, 16 KB, 32 KB,
64 KB, or 128 KB.
A larger stripe size produces better-read performance, especially if your computer
does mostly sequential reads. However, if you are sure that your computer does
random reads more often, select a small stripe size.

HDD for example, the actual size read by the controller maybe 40.55GB. This
function “capacity truncation” can be used to trim down the capacity to 40.00
GB. This function is useful because in the future the 40.55HDD might go bad, and
the user can’t locate another 40GB drive which contains 40.55GB in the actual

that you want to configure the Fiber Channel parameter.
Make sure to check "Confirm The Operation" then click "Submit" button for change to
come into effect.
4.11.2.2 Channel Speed
Each FC Channel can be configured as 2Gbps, 4Gbps, 8Gbps or use "Auto" option
for auto speed negotiation between 2Gb / 4Gb / 8Gb. The controller default is "Auto",
which should be adequate under most conditions. The Channel Speed setting takes
effect for the next connection. That means a link down or bus reset should be applied
for the change to take effect. The current connection speed is shown at the end of the
row. You have to click the "Fiber Channel Config" link again from the Menu Frame to
refresh display of current speed.
4.11.2.3 Channel Topology
Each FC Channel can be configured as Auto, Loop, Point-to-Point, or Fabric
Topology. The controller default is "Auto" topology, which takes precedence of Loop
topology. Firmware restart is needed for any topology change to take effect. The

current connection topology is shown at the end of the row. You have to click the
"Fiber Channel Config" link again from the Menu Frame to refresh display of current
topology. Note that current topology is shown as "None" when no successful
connection is made for the channel.
4.11.2.4 Hard Loop ID
This setting is effective only under Loop topology. When enabled, you can manually
set the Loop ID in the range from 0 to 125. Make sure this hard assigned ID is not
conflicted with any other devices on the same loop; otherwise the channel will be
disabled. It is good to disable the hard loop ID and let the loop itself auto arrange the
Loop ID.
4.11.3 Ethernet Config
Use this feature to set the controller’s Ethernet port configuration. Customer doesn’t
need to create a reserved space on the arrays before the Ethernet port and HTTP
service are working. The firmware-embedded Web Browser-based RAID manager
can access it from any standard internet browser or from any host computer either
directly connected or via a LAN or WAN with no software or patches required.
DHCP (Dynamic Host Configuration Protocol) is a protocol that lets network
administrators manage centrally and automate the assignment of IP (Internet
Protocol) configurations on a computer network. When using the Internet's set of
protocols (TCP/IP), in order for a computer system to communicate to another
computer system it needs a unique IP address. Without DHCP, the IP address must
be entered manually at each computer system. DHCP lets a network administrator
supervise and distribute IP addresses from a central point. The purpose of DHCP is to
provide the automatic (dynamic) allocation of IP client configurations for a specific
time period (called a lease period) and to eliminate the work necessary to administer
a large IP network.

For example:
It is rarely that the actual size of the Hard Drive is a whole number. Let’s take a
40GB HDD for example, the actual size read by the controller maybe
40.55GB. This function “capacity truncation” can be used to trim down the
capacity to 40.00 GB. This function is useful because in the future the
40.55HDD might go bad, and the user can’t locate another 40GB drive which
contains 40.55GB in the actual capacity, then that particular user will have to
buy another drive with bigger capacity to rebuild the raid volume.

5.5.7.1 DHCP Function
DHCP (Dynamic Host Configuration Protocol) is a protocol that lets network
administrators manage centrally and automate the assignment of IP (Internet
Protocol) configurations on a computer network. When using the Internet's set
of protocols (TCP/IP), in order for a computer system to communicate to
another computer system it needs a unique IP address. Without DHCP, the IP
address must be entered manually at each computer system. DHCP lets a
network administrator supervise and distribute IP addresses from a central point.
The purpose of DHCP is to provide the automatic (dynamic) allocation of IP
client configurations for a specific time period (called a lease period) and to
eliminate the work necessary to administer a large IP network.
To manually configure the IP address of the controller, move the cursor bar to
the Main menu Ethernet Configuration Function item and then press the Enter
key. The Ethernet Configuration menu appears on the screen. Move the cursor
bar to DHCP Function item, then press Enter key to show the DHCP setting.
Select the “Disabled’ or ‘Enabled” option to enable or disable the DHCP

Software Operation Manual
5.5.7.2 Local IP address
If you intend to set up your client computers manually, make sure that the
assigned IP address is in the same range of your default router address and that
it is unique to your private network. However we would highly recommend that if
you have a network of computers and the option to assign your TCP/IP client
configurations automatically, please do. An IP address allocation scheme will
reduce the time it takes to set-up client computers and eliminate the possibilities
of administrative errors.
To manually configure the IP address of the controller, move the cursor bar to
the Main menu Ethernet Configuration Function item and then press the Enter
key. The Ethernet Configuration menu appears on the screen. Move the cursor
bar to Local IP Address item, then press Enter key to show the default address

6.1.2 Multipath I/O & No single point of failure
Multipath I/O is a I/O path fault tolerance and performance enhancement
technique, which requires more than one physical I/O path between the host
server and its corresponding storage devices. I/O path redundancy provides the
data protection with multiple I/O paths between the host server and the
corresponding storage subsystems.
6.1.3 Configuration & connectivity
Redundant RAID subsystem implements ALAU (Asymmetric Logical Unit
Access) algorithm which allows Volume Sets to be accessed by only one
controller when both controllers are on-line. The controller, which controls the
Volume Sets, is the preferred controller and another controller is for standby. For
example, Volume Set #000 is controlled by controller A, and the redundant
RAID subsystem allows host server access Volume Set #000 only through
controller A. Controller B would take over the data I/O if controller A fails. Figure
1 shows the standard connectivity for a single volume.
138
Chapter 6. Redundant Storage Subsystem & Multipathing I/O
Figure 1
Redundant RAID subsystem default assigns even Volume Sets to controller A
and odd Volumes Sets to controller B. For example, controller A is the preferred
controller for Volume Set #000 and controller B is the preferred controller for
Volume Set #001 and so on.
The method to configure RAID Sets is the same with the single controller
subsystem, such as creating RAID Sets, creating volume sets and etc. To
ensure the I/O redundancy, both two controllers must be connected to the host
server. Physical connectivity of redundant RAID subsystem is described at

Fiber Channel is a set of standards under the auspices of ANSI (American
National Standards Institute). Fiber Channel combines the best features from
SCSI bus and IP protocols into a single standard interface, including
high-performance data transfer (up to 800 MB per second), low error rates,
multiple connection topologies, scalability, and more. It retains the SCSI
command-set functionality, but uses a Fiber Channel controller instead of a
SCSI controller to provide the network interface for data transmission. In today's
fast-moving computer environments, Fiber Channel is the serial data transfer
protocol choice for high-speed transportation of large volumes of information
between workstation, server, mass storage subsystems, and peripherals.
Physically, the Fiber Channel can be an interconnection of multiple
communication points, called N_Ports. The port itself only manages the
connection between itself and another such end-port which, which could either
be part of a switched network, referred to as a Fabric in FC terminology, or a
point-to-point link. The fundamental elements of a Fiber Channel Network are
Port and node. So a node can be a computer system, storage device, or
Hub/Switch.
This chapter describes the Fiber-specific functions available in the Fiber
channel RAID controller. Optional functions have been implemented for Fiber
channel operation only available in the Web browser-based RAID manager. The
LCD and VT-100 can’t configure the options available for Fiber channel RAID
controller.
TThhrreeee w
waayyss ttoo ccoonnnneecctt ((FFC

A topology defines the interconnection scheme. It defines the number of devices
that can be connected. Fiber Channel supports three different logical or physical
arrangements (topologies) for connecting the devices into a network:
* Point-to-Point
* Arbitrated Loop (AL)
* Switched (Fabric)
The physical connection between devices varies from one topology to another.
In all of these topologies, a transmitter node in one device sends information to
176
Appendix B. Fiber Operation
a receiver node in another device. Fiber Channel networks can use any
combination of point-to-point, arbitrated loop (FC_AL), and switched fabric
topologies to provide a variety of device sharing options.
Point-to-point
A point-to-point topology consists of two and only two devices connected by
N_ports of which are connected directly. In this topology, the transmit Fiber of
one device connects to the receiver Fiber of the other device and vice versa.
The connection is not shared with any other devices. Simplicity and use of the
full data transfer rate make this Point-to-point topology an ideal extension to the
standard SCSI bus interface. The point-to-point topology extends SCSI
connectivity from a server to a peripheral device over longer distances
Arbitrated Loop
The arbitrated loop (FC_AL) topology provides a relatively simple method of
connecting and sharing resources. This topology allows up to 126 devices or
nodes in a single, continuous loop or ring. The loop is constructed by
daisy-chaining the transmit and receive cables from one device to the next or by
using a hub or switch to create a virtual loop. The loop can be self-contained or
incorporated as an element in a larger network. Increasing the number of
devices on the loop can reduce the overall performance of the loop because the
amount of time each device can use the loop is reduced. The ports in an
arbitrated loop are referred as L-Ports.
Switched Fabric
A switched fabric a term is used in a Fiber channel to describe the generic
switching or routing structure that delivers a frame to a destination based on the
destination address in the frame header. It can be used to connect up to 16
million nodes, each of which is identified by a unique, world-wide name.
In a switched fabric, each data frame is transferred over a virtual point-to-point
connection. There can be any number of full-bandwidth transfers occurring
through the switch. Devices do not have to arbitrate for control of the network;
each device can use the full available bandwidth.
A fabric topology contains one or more switches connecting the ports in the FC
network. The benefit of this topology is that many devices (approximately 2-24)
can be connected. A port on a Fabric switch is called an F-Port (Fabric Port).
Fabric switches can function as an alias server, Multicast server, broadcast
server, quality of service facilitator and directory server as well.

The following elements are the connectivity of storages and Server components
using the Fiber channel technology.
Cables and connectors
There are different types of cables of varies lengths for use in a Fiber Channel
configuration. Two types of cables are supported: Copper and optical (fiber).
Copper cables are used for short distances and transfer data up to 30 meters
per link. Fiber cables come in two distinct types: Multi-Mode fiber (MMF) for
short distances (up to 2km), and Single-Mode Fiber (SMF) for longer distances
(up to 10 kilometers). The controller default supports two SFP connectors.
Fiber Channel Adapter
Fiber Channel Adapter is devices that connect to a workstation, or server and
control the electrical protocol for communications.
Hubs
Fiber Channel hubs are used to connect up to 126 nodes into a logical loop. All
connected nodes share the bandwidth of this one logical loop. Each port on a
hub contains a Port Bypass Circuit (PBC) to automatically open and close the
loop to support hot plug ability.
Switched Fabric
Switched fabric is the highest performing device available for interconnecting
large numbers of devices, increasing bandwidth, reducing congestion and
providing aggregate throughput. .
Each device connected to a port on the switch, enabling an on-demand
connection to every connected device. Each node on a Switched fabric uses an
aggregate throughput data path to send or receive data

SNMP, an IP-based protocol, has a set of commands for getting the status of
target devices. The SNMP management platform is called the SNMP manager,
and the managed devices have the SNMP agent loaded. Management data is
organized in a hierarchical data structure called the management Information
Base (MIB). These MIBs are defined and sanctioned by various industry
associations. The objective is for all vendors to create products in compliance
with these MIBs so that inter-vendor interoperability can be achieved. If a
vendor wishes to include additional device information that is not specified in a
standard MIB, then that is usually done through MIB extensions.

Before the manager application accesses the RAID controller, user needs to
integrate the MIB into the management application’s database of events and
status indicator codes. This process is known as compiling the MIB into the
application. This process is highly vendor-specific and should be well-covered
in the User’s Guide of your SNMP application. Ensure the compilation process
successfully integrates the contents of the XXXX.MIB file into the traps
database.

Depending upon the SNMP management application used, the MIB must be
