Vixel InSpeed™ SAN Storage Switch Model 375 for use in Fibre Channel applications in typical
entry-level Storage Area Networks (SANs).

OVERVIEW

The Vixel InSpeed™ SAN Storage Switch Model 375 is designed for entry-level Storage Area
Networks (SANs), which provide the following advantages over direct attached storage:

• Greater application availability

• Higher performance between servers and storage devices

• Improved storage asset utilization

• Lower storage management and support costs

• Incremental scalability to keep up with difficult to estimate storage growth

This switch is ideal for storage pooling and consolidation, high-performance shared tape library

INSPEED™ TECHNOLOGY

Vixel’s InSpeed™ technology is an advanced switching architecture that couples a non-blocking
crossbar switch with a uniqu e swi tch po rt log ic a nd per-por t SE RDES . T his re sults in the indu stry’s
highest density Fibre Channel switch on a chip (SOC). The port logic is based on Fibre
Channel-Arbitrated Loop (FC-AL), an ANSI standard (X3T11) designed to provide shared
bandwidth over low-cost media.

This architecture enables the sw itch’s router to send data directly fro m one port to another,
allowing for multiple, simultan eous conversations betw een ports—eff ectively multiply ing
bandwidth. InSpeed™ provides the same performance as complex fabric switches that support
FC-SW2. InSpeed™ can even exceed fabric switch performance in entry-level SAN environments,
where the overhead associated with longer name addressing and services is not beneficial.

SWITCH APPLICATIONS

The Vixel InSpeed™ SAN Storage Switch Model 375 is ideal for consolidation and shared storage
pooling, high-performance shared tape library backup and recovery, server clustering, and
streaming rich media applications. The following sections provide examples of these applications.

Storage Consolidation and Shared Storage Pooling

In this configuration, the switch enables multiple hosts to share single or multiple storage
systems. This application replaces direct-attached configurations that require multiple storage
systems to be attache d to separate s ervers, which ofte n resu lts in diffi cult t o ma nage mu ltipl e
systems and trapped, unused storage islands (storage cannot be shared with other servers).

Benefits include:

• Improved incremental scalability–connect up to 20 hosts and/or other storage devices,
including tape libraries, to a single switch.

• Lower storage management support costs.

• Improved capacity utilization that enables effective use of both servers and storage.

For larger system environments, multiple switches can be connected and Automatic Tr unking can
be used to keep performance and availability at high levels. As a best practice when using
multiple switches, co nnect s ervers and th eir rel ated s torage devi ces t hrough the sa me s witch to
optimize performance.

IN THE FUTURE OF STORAGE 4

Figure 1-2 depicts a sample multiple switch storage consolidation configuration in which multiple
servers communicate with storage devices an d zoning is incorpo rated. The zoning i n Figure 1-2
might be set up to configure a multiple operating sy stem environment. For example, Z one 1 mi ght
be Windows-based, Zone 2 might be Linux-based, and Zone 3 might be Unix-based. Zoning can
also be used to improve security by masking storage devices or fil es. For example, a finance
department could secu re f inancia l files from view ing by th e engineering department, wh ich in turn
could secure engineering files from viewing by the finance department.

Tape Library Consolidation

Another switch application is the consolidation of multiple tape libraries attached to individual
servers into a single library for all servers for backup and restore purposes.

Benefits include:

• Improved cost effectiveness.

• Improved availability for performing system backups:

• Of f-LAN System Backups o ften reduce the amount of time it takes backups (and
recovery) to occur because SANs run at higher performance bandwidth than LANs.

• Server-less backups enable applications to remain fully active during backup and
recovery processes, when combined wit h the appropriate backu p software
solution.

Figure 1-3 depicts a sample tape library consolidation configuration.

Figure 1-3: Before consolidation, backup and restore
data must travel on the LAN, congesting traffic and
operating at slow speeds.

After consolidation, backup and
restore data travels on the high speed
SAN separate from LAN traffic.

Rich Media

For rich media applications, the switch provides improved storage and file sharing from a single
storage pool for multiple workstations.

Figure 1-4 depicts a sample rich media configuration.

Server Clustering

In this configuration, the switch helps deliver improved application availability when combined
with a server clustering software solutio n, like Microsoft Clu ster Server or Veritas Cluster Server.
This prevents system downtime in case of failure to one of the application servers.

Figure 1-5 depicts a sample server clustering configuration.

SFP COMPATIBILITY

SFPs are “hot-pl uggable” into the swit ch, which a llows host com pute rs, s ervers, and storage
devices to be added dynamically without requiring power removal from the switch or any
connected devices.

The switch supports Small Form-Factor Pluggable (SFP) modules that comply with the SFP
specification as produced by the MSA consortium and have passed Vixel’s qualification testing.

The following manufacturers of 1-2Gb optical, shortwave SFPs are recommended:

• Finisar

•JDS Uniphase

Contact a customer service representative to request the certified part numbers for these
vendors.

Installing an SFP

If the Chan ge N oti fica ti on on In serti on pol icy i s e nab led, pl ug gin g a n SF P int o t he swi tch will
automatically send an F7 Initialization notification to indicate the device is ready to begin
initialization.

To insert an SFP:

1. Remove dust covers or plugs from the SFPs, if provided.

2. Slide the SFP into the port, ensuring correct polarity, until the latch clicks into place.

Removing an SFP

To extract an SFP:

Determine what kind of extraction mechanism the SFP has and remove the SFP as follows:

If the SFP has a removal tag, remove the cable from the SFP and then pull the removal tag
outward and toward the side of the SFP with the tag.

If the SFP has a small plastic slider on the top or bottom, remove the cable from the SFP and
then push in the slider and hold while pulling out the SFP.

If the SFP has a bale (small metal clasp), remove the cable from the SFP and then unlatch,
pivot, and pull the bale.

Attaching a Device to the Switch

To attach a device:

1. Make sure that the device is FC-AL compatible.

2. Attach a cable to the device.

3. Attach the other end of the cable to an SFP.

4. Make sure that the device and switch are o perational and set to the same sp eed.

Caution: Forcing an SFP into a port may damage the SFP and/or port.

BOOTING THE SWITCH AND SAN

The following procedure is recommended when booting the switch and SAN. Before powering on
the switch and SAN, read the Release Notes, included with the switch contents, to determine any
modifications that may be required for a specific installation.

To boot the switch and SAN:

1. Power on the storage devices (such as JBODs, tape libraries, and RAIDs).

2. Insert the plug end of the switch’s power cord to a properly grounded power source.

3. Insert the power cord’s IEC connector end into the switch’s power receptacle.
The switch powers on a nd runs Power-On Self-Test (POST) diagn ostics t o verif y the

fundamental integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then,
excluding the Ethernet Link, Power Supply/Fan Module, and Power LEDs, the LEDs turn off
(LEDs extinguish). Once the switch is op erational, the LEDs display curre nt status as
described in “Switch LEDs” on page 9.

4. Power on any other switches connected to the SAN.

5. For certain applications, switch configuration must be completed befo re continuing with
the next step. For information regarding switch configuration, see Chapter 3: Switch
Management.

6. After all switches have initialized, power on the hosts.
The network initializes.

7. Check all port LEDs.
The SAN should be fully operational at this point. However, it is appropriate to ensure

proper discovery has taken place and all required devices are participating in the network.
Some host bus adapters may provide this level of functionality or it might be resident in
the application software on the host operating system.

Note: The power cord’s IEC connector plug serves as the switch’s disconnect device.

To cycle power to the switch, remove and reconnect the switch’s power cord.

Note: FC-AL compatible nodes must perform initialization procedures upo n power-up

in order to func tion pro perly. It is the responsib ility of the Fib re C hanne l dr iver
software on FC-AL nodes to perfor m this initia lizatio n.

POWER SUPPLY/FAN MODULE REPLACEMENT

The Vixel InSpeed™ SAN Storage Swit ch Model 375 has hot -sw appable power supply/fan modules
for high availability. A power supply/fan module consists of an individual power supply and a fan
bank consisting of three fans.

The switch can run on one functi oning pow e r su pply/fan module indefinitely, as long as the faulty
power supply/fan module remains installed in the switch and there are at least two fans
operational in each module’s fan bank. If the power supply/fan module is removed from the
switch, the switch will continue to operate normally for approximately 20-30 minutes. Non­functional modules should be immediately replaced to maintain high availability.

To remove an old power supply/fan module:

1. Have the new power supply/fan module clo se to the switch fo r quick inser tion. (This st ep
ensures that the pr ocedu re takes no lon ger t han n ecessa ry—the sw itch can only o perate
with one power supply/fan module installed for approximately 20-30 minutes.)

2. Unplug the power cord from the faulty module’s power receptacle.

3. Slide the safety latch over the power receptacle to expose the thumb screw.

4. Loosen the two thumb screws. No tools are required.

5. Pull the unscrewed power supply/fan module out of the switch’s module bay using the
module’s handl e.

To insert a new power supply/fan module:

1. Align the power supply/fan module with the module bay o pening. Ensu re th e warnin g label
is facing up war ds o n t h e mo du le.

2. Carefully slide the module into the opening. Ensure the module is seated firmly in the
module bay (the module should be flush with the switch’s face).

3. Tighten the two thumb screws. No tools are required.

4. Slide the safety latch over the thumb screw (uncovering the power receptacle).

5. Plug the power cord into the module’s module power receptacle.

Note: Keeping spar e power su pply/ fan mod ules (Part N umbe r 60131 9) in stoc k is highl y

recommended. Con tact a sale s represe ntative for fur ther infor mation.

Note: The alternate power supply/fan module should remain powered on while the

faulty module is removed and replaced to guarantee switch availability.

WARNING

To avoid an electrical hazard, never apply power to the power
supply/fan module while the module is removed from the switch.

Note: When using a screwdriver to tighte n the thum b scre ws, ens ure t he thu mb

screws are secure but not overtightened. Overtightening the thumb screws may
damage the screws or the module.

CHAPTER 3SWITCH MANAGEMENT

This chapter is divided into three sections providing information on how to manage and monitor
the switch:

• Getting Started – Describes how to configure the network interface, use the Web
Manager, and perform a basic initia l set up of the s witc h.

• Managing the Switch - Describes how to configure the switch and port settings, manage
firmware versi ons a nd conf igurat ion f iles, set sw itch t hres hold s, and confi gure O ne-Ste p

• Monitoring the Switch – Describes how to view switch information, the event log, port
information, and port diagnostics.

The switch incorporates two distinct interfaces for managing and monitoring purposes:

• The Web Manager interface provides an intuitive graphical user interface that enables
users to quickly check swit ch status or modify switch setti ngs in a visual envi ronment.

• The Command Line Interface (CLI) provides flexi bility and additional fu nctionality f or
advanced users.

Both of these interfaces provide nearly identical functionality; however, for the purposes of this
guide, the Web Manager interface is used for switch and port configuration unless otherwise
noted.

For a list of CLI commands, see Appendix B: CLI Quick Reference on page 63. For additional

Web Manager. Once the switch’s network settings are configured, use the Web Manager to
perform a quick switch setup.

Configuring the Network Interface

Before using the Web Manager, ensure the switch’s ethernet network parameter settings are
correct for the network co nfiguration. The switch shi ps with the fo llowing de fault IP settings:

• IP Address: 169.254.10.10

• Netmask: 255.255.0.0

• Gateway: 0.0.0.0

To adjust these settings to open the Web Manage r, connect to the switch using the provided serial
interface cable and follow the instructions below.

To connect through a serial interface:

1. Attach one end of the included RS-232 null modem cable to the computer’s DB-9 serial
port and attach the other end to the switch’s DB-9 serial port.

2. Open a terminal session through a serial terminal emulation program (such as
HyperTer minal®) with the appropriate serial port (for example, COM1) and the following
serial port parameters:

• Bits per second: 19200

• Data bits: 8

•Parity: None

•Stop bits: 1

• Flow control: None

3. If using HyperTerminal, press E

NTER to receive a prompt.

If using the tip command on a UNIX workstation, do the following:

a. View the /etc/remote file and create an alias similar to Hardware but with the

serial port parameters above. (Suggested name: Switch)

b. Use the tip command to establish a connection through the created alias, for

example tip switch. (For more information, see the tip command M anual page.)

4. Type the password at the prompt and press E

NTER. (The default password is password.)

5. From the serial terminal emulation program, type config network ip and press E

NTER.

The switch’s current IP parameters are displayed with a prompt for entering the IP
address.

6. Change the IP address and press E

NTER.

7. Use the mask and gateway commands to change the su bnet mask and default gateway
respectively.

8. Type save and press E

NTER.

9. Type root reset and press E

NTER.

10. Type y and press E

NTER to reset the switch.

11. Attach the computer to the switch’s 10/100 ethernet connector by doing one of the
following:

• Attach an ethernet RJ-45 cross-over cable directly between the computer and the
switch.

• Attach two ethernet RJ-45 twisted pair cables from the computer and the switch
into an opera tiona l et her net pa tch p anel o r hub.

Default Smart Settings

There are several default Smart Settings available on the switch. These default Smart Settings
were defined by Fibre Channel storage experts to ensure the switch is optimally configured for
performance and stability.

The default Smart Settings cannot be modified or deleted, but these settings can be used as
templates for creating custom Smart Settings.

Initiator or Target

This Smart Setting is the default se tting for all switch ports from the factory. This setting offers no
change protection and all settings are set to their default values. Initiators and targets can be
connected to ports that are set to this Smart Setting.

This is the recommended Smart Setting for setups with targets and initiators connected to a
single switch.

Initiator with Stealth

This Smart Setting is used when connecting a host device to the port. When a port is set to this
Smart Setting, change notifications are not sent from the initiator to other devices, but change
notifications are re ceived by the init iator.

This Smart Setting is appropriate for embedded storage controllers and external Host Bus
Adaptors (HBAs) or servers wit h installed HB As.

Target with Stealth

This Smart Setting is used when connecting embedded storage devices, like JBODs, SBODs, tape
drives, or external RAID systems (J BODs, SBODs, or tape libraries). Whe n a port is set to this
Smart Setting, change notificatio ns are sent to other devi ces, but change noti fications are not
received by the target.

Fabric Connection

This Smart Setting is used when connecting a port to a Fabric switch. Only one connection from
the Vixel InSpee d™ SAN Storag e Switch Mo del 375 t o a Fabric switch is valid .

Tree Cascade

This Smart Setting is used when connecting two or more switches together in a tree
configuration. Up to four tree cascades are supported between switches. See “Cascading
Switches” on page 44 for additional information.

String Cascade

This Smart Setting is used when connecting two or more switches together in a string
configuration. Up to four string cascades are supported between two switches. See “Cascading
Switches” on page 44 for additional information.

Before selecting a cascade optio n, consider t he following:

• Cascade ports of like number should be connected together. For example, connect port 1
of Switch A to port 1 of Swi tch B, connec t po rt 2 of Switch B to port 2 of Swi tch C, and s o
on.

• Cascade port numbers must be lower than non-cascade port numbers (for example,
Initiator or Target ports). Therefore, select cascade types before selecting these non ­cascade types.

• A maximum of three switches may be connected using string cascades.

Note: Changing the Smart Setti ng of a port may affe ct th e perf orm ance or b ehavior of t he

system. Depending on the implem entation, some Sm art Setting s are more ap propria te
than others.

VIXEL INSPEED™ SAN STORAG E SWIT C H MODEL 375 CHAPTER 3 SWITCH MANAGEMENT
USER’S GUIDE

EMBEDDED

IN THE FUTURE OF STORAGE 31

This policy takes precedence over all other policies. When this policy is
disabled, no additional policies are operational, and as long as a port
transmits a signal of the correct freque ncy and amplitude, the port wil l
be allowed in the zone .

Port Test Before Insertion This policy ensures a device on a port is a valid, standards-compliant

participant befo re allow ing the dev ice to be ins erted in to a zone. Th e
device must meet a ll of the FC-AL require ments along with go ing
through a complete change notification cycle. During the change
notification cycle, the device becomes the Initialization Master (IM)
and goes through the change notification phases. Once the change
notification cycle is compl ete, the device can be inserted. This process
ensures a bad de vice is not allow ed into the zo ne.

Setting Description

Port Control Th e me thod for c ontr olling a por t. Op tio ns inclu de:

• auto – the default setting. The switch will automatically insert a port
based on policy settings. This prevents the insertion of incompatible
ports, which may cause disruption.

• bypass – removes a port from the network. Use this mode to keep a
device out of an initialization cycle when troubleshooting.

• extLoopb ack – re moves a port f rom the network and ro utes the
port's receive signal back through the port's transmitter. Us e this
mode to isolate a specific zone for trou bleshooting or to test a
transceiver’s circuitry and attached media from the n ode end.

• insert – allows ports whose transceivers cannot derive a valid clock
or "K" character (Ordered Set) to join a zone. Use this mode
cautiously – devices without valid characters may put bad data into
a zone, causing the zone to go down.

Bypass on Clock Delta The switch determines the relative freq uency of the signal bein g

received by a port to the internal switch clock. The result of this
test allows the dete rmina tion of h ow f ar a part in fre quency the
switch’s clock is in relation to the clock of the received signal – the
clock delta. If the clock delta exceeds a set threshold, the switch is
notified and the port may be bypassed if necessary. Typically, clock
drift is slow enough to a llow the re moval and repla cem ent of a

One-Step Zoning

Zoning allows ports to be divided into multiple virtual zones (or work groups), similar to Virtual
Local Area Networking (VLAN). By separating activity on the network, zoning also eliminates
change notification propagation (change notifications that occur within one zone cannot
propagate to other zone s.)

Use zoning to:

• Separate different operating system environments.

• Temporarily block or grant access during backup or other tasks.

• Consolidate equipment logically.

• Designate closed user groups for increa sed security.

• Separate test or maintenance areas from prod uct ion a reas .

Zone configuration settings are available on the Web Manager’s One-Step Zoning page. The page
is arranged as a grid of check boxes for placing ports in appropriate zones. Ports are listed across
the top of th e gr id. Zone s are listed down the left side. Similar to other Web Manager pages, the
port color represents the current port status.

To view the One-Step Zoning page:

Click Advanced Functions > One-Step Zoning.

The switch is capable of up to twelve zones. Initially, all ports reside in Zone 0. However, a port
will clear from Zone 0 whenever it is selected and placed in another zone.

The color of each zone indicates its stat us. See the descri ptions in the fo llowing tabl e:

Color Description

Down (red) One or more port s h a ve been s el ected , zo nin g has be en ac ti vated, but

hardware has caused a failure.

Single-Switch Zoning

The simplest zoning configuration is to place each port into a single zone, so that zones are
separate from each other as shown in Figure 3-13.

In Figure 3-13, zone 1 includes ports 1, 3, and 4, while zone 2 includes ports 2 and 5. Devices on
ports 1, 3, and 4 have direct access to each other and devices on ports 2 and 5 have direct access
to each other; however, devices 1, 3, and 4 ar e separated from devices 2 and 5.

Caution: Clearing the Zoning A ctive check box will de activate all zones , which may

degrade system performance or compromise security.

Adding Devices to Multiple Zones

In the previous example, each host only communicates with the devices in the same zone as the
host. However, there may be situations in which hosts in separate zones need to share devices.
When this situation occurs, use overlapping zones to share the devices between the hosts. Figure
3-15 depicts this type of zoning configuration.

In Figure 3-15, zone 1 includes ports 1, 3, and 4, while zone 2 includes ports 2, 4 and 5. Port 4 is
in both zones. Devices on ports 1, 3, an d 4 have direct acce s s t o ea ch oth er an d devi ce s on po rt s
2, 4, and 5 have direct access to each other, but devices 1 and 3 are separated from devices 2
and 5. The device on port 4 has direct access to all the devices on ports 1, 2, 3, and 5.

To add storage devices to multiple zones:

1. Select the appropriate zones for each port.

2. Ensure the Zoning Active check box is selected.

Multiple Switch Zoning

Zones can be configured across multiple switches using a similar procedure to a single switch.
However, multiple-switch zoning requires some coordination between the switches. Building on
the example for ports in multiple zones, move the devices onto two switches and have the zones
stretch between the two, as in Figure 3-17.

In Figure 3-17, zone 1 includes ports 2, 4, 5, and cascade port 1, while zone 2 includes ports 3, 5,
6, and cascade port 1. Ports 1 (cascade port) and 5 are in both zones.

To configure multiple-switch zoning, do the following for each switch:

1. Plan which ports should belong in each zone.

2. From the One-Step Zoning page, select the appropriate ports for each zone.

3. Ensure the Zoning Active check box is selected for both switches.

4. After making changes, click Submit.

AL_PA Zoning

Another zoning configuration is AL_PA zoning, which enables users to specify that certain devices
only communicate with one another. AL_PA zoning is only accessible through the Command Line
Interface (CLI). Refer to the InSpeed Storage Switch CLI Reference Guide for additional
information.

Recovering a Bad Zone Automatically

Bad zone recovery policy automa tically reco vers tr affic if a device has brought down the zone. The
zone state is monitored continuously. If ports are inserted into a zone, but the zone state never
transitions to the Zone Up or Zone Active state after a set period of time (Hold Time), all devices
in the pertinent zone are bypassed and then allowed to reinsert. There is a secondary timeout,
the Bad Zone Recovery Delay Time, that can also be configured. The Bad Zone Recovery Delay
Time causes a delay before ports are allowed to reinsert, which prevents a high "thrashing" level
of port insertions and de-insertions and ensures that some devic es can reset. The Bad Zone
Recovery Hold Time and Delay Time threshold settings are available on the Advanced Functions
Switch Thresholds page.

When this policy is enabled with the associated PTBI policy, the device causing a zone to go down
is not allowed back into the zone due to the PTBI policy, which allows the system to return to
normal operation. The combination of the Bad Zone Recovery and PTBI policies has resulted in
significant improvements to SAN availability.

To activate bad zone recovery:

1. Click Advanced Functions > One-Step Zoning.

2. Under Bad Zone Recovery, select the check boxes for the appropriate zones.

3. Click Submit.

Caution: Clearing the Zoning Active check box will deactivate all zones, wh ich m ay

Connecting Ports Through Hard Zoning

A Hard Zone can be used to add a separate 126 AL_PAs that operate in isolation from any other
zone. A Hard Zone disables switching functionality and creates a shared con nection between the
ports in a zone topology, splitting the switch into multiple unique FC-AL zones. When Har d Zoning
is enabled, all switch zones must be Hard Zones. A combination of Hard Zones and regular zones
on a single switch is not allowed.

The advantages of Hard Zoning include:

• Each Hard Zone contains 126 available AL_PAs.

• The switch can be configured to contain up to eleven isolated Hard Zones.

The limitations of Hard Zoning include:

• 2 Gb of shared bandwidth over the entire Hard Zone.

• Ports in a Hard Zone cannot use the Stealth Intelligent Change Manager.

• Automatic Trunking and route blocking are not allowed in a Hard Zone.

• Ports in a Hard Zone cannot be set to a string or tree cascade configuration.

• Device AL_PAs on a port in a Hard Zone cannot be displayed.

The Hard Zone setting is available on the One-Step Zoning page. To view the page, click

Advanced Functions > One-Step Zoning.

To set up Hard Zoning:

1. Determine which ports will reside in each Hard Zone and ensure the ports are in only one
Hard Zone.

2. Under Hard Zone, select the check boxes for the appropriate zon es.

3. Click Submit.

Caution: Do not set a Hard Zone for ports in mu ltiple zones or share ports that have the Hard Zone

Cascading Switches

When multiple switches are connected, the connecting links between the switches are referred to
as "cascades". There are two distinct cas cade configuratio ns to consider wh en configuring
networks for optimal performance and connectivity: string cascades and tree cascades.

String Cascades

A string cascade connects multiple switches (up to three switches maximum) together in a "daisy­chained" configuration. When one device requests access to another device, the request is sent to
each switch in the casca de befo re device acc ess is granted. This arbitration meth od pro mote s
fairness between the switches. However, when compared to tree cascades, string cascades offer
less performance due to the increased latency between the switches.

When configuring a switch port for a stri ng cascade, use the St ring Cascade S mart Setting. To
reduce contention and improve performance between in itiato r tr affic and tar get traffic when using
a string cascade configuration, connect the ports of each switch togeth er using the same Strin g
Cascade Smart Settings. For example, in Figure 3-20 the three switches are connected through
two string cascades using the String Cascade - Trunk 1 and String Cascade - Trunk 2 Smart
Settings. This creates two dedicated paths through which initiators and targets can communicate.

Tree Cascades

Tree cascades provide the best performance (lowest latency) configuration. A tree cascade
consists of a root swit ch con nected to addi tional swit ches ( up to 8 s witches maximu m). W hen a
device on a switch requests access to another device, the request is sent the particular switch for
that device. The limitation to the tree cascade configuration is the random nature of devices
gaining access to one anot her, as fairness is not used for tree cascades.

When configuring a port for a tree cascade, use the Tree Cascade Smart Setting.

Automatic Trunking

Multiple links between switches are called “trunks”. Trunks provide higher bandwidth across
cascaded switches for systems inco rporating multiple initi ators. Each tru nk can improve system
throughput and provide “failover” capability. A maximum of 4 trunks between each switch is
supported. Trunking is performed automatically when ports are configured properly. Figure 3-22 is
an example of Automatic Trunking.

Each trunk is part of a trunk group. A trunk group consists of two or more cascades between two
switches. There can only be one trunk group between two switches. Each trunk group c ontains a
primary trunk. All traffic flows through the primary trunk on a switch unless specified otherwise
using the Load Balancing feature. The primary trunk is always the lowest numbered port of any
trunk group.

If the primary trunk fails, the secondary trunk automatically becomes the primary trunk unless
otherwise configured. Multiple cascades also enable switch configuration for better performance
through load balancing (see “Load Balancing” on page 46).

The Automatic Trunking page enables users to configure trunking by defining trunk groups and
assigning ports to those groups. The Automatic Trunking feature is available when one or more
ports are assigned a String or Tree Cascade Smart Setting.

To configure Automatic Trunking:

1. Click Advanced Functions > Automatic Trunking.
The Automatic Trunking page appears.

2. Select a trunk group for each port by clicking the appropriate Trunk Group option.

3. When finished making changes, click Submit.

IN THE FUTURE OF STORAGE 46

Load Balancing

Load balancing builds on the Automatic Trunking functionality by specify ing the path t hat the data
uses to flow between multiple switches. Users can manage the switch’s aggregate bandwidth by
manually distributing traffic across multiple casca de ports as shown below. A cascade port is a
port that is attached to another switch of the same type and configured as a String or Tree
Cascade Smart Setting on the Port Smart Settings page. All data flows through the primary
cascade, unless the switch is confi gured differe ntly.

In Figure 3-24, host 1 uses cascade port 1, while host 2 uses cascade port 2. All traffic will use
the lowest numbered (primary) cascade port by default but ports may be configured to use other
cascades.

Load balancing configuration settings are available on the Web Manager’s Load Balancing page.
Before implementing load balancing on the switch, the au tomatic trunki ng settings must be
configur ed. Se e “Aut om ati c Trunking” on pa ge 45 for a ddi ti on al i nfo rm ati on .

To view the Load Balancing page:

Click Advanced Functions > Load Balancing.

Note: Cascade ports must be properly configured before load balancing will work.

Note: When tape drives or ta pe librarie s a re inclu de d in m ul tiple swi tch c on figurat ions

incorporating m ult iple trun ks, place th e tap e d rive o r ta pe library a nd a ny de vic es t hat
access those devices on the secondary (duplicate) trunk, not the primary trunk.

The page is arranged as a grid of check boxes for assigning ports to cascades ("Trunk Groups").

Load Indicators

The Load Balancing page incorporates two sets of visual indicators for measuring traffic:

• Port Load Indicators–the horizontal bars on the right side of the page that display the
current load for each port.

• Trunk Load Indicators–the vertical bars at the bottom of the page that display the current
load for each trunk group.

These bars indicate the amount of traffic across a trunk or port. The size of the bars increase in
correlation to the amount of traffic and, as a bar’s size increases, can iden tify a specific tr unk or
port that is overloaded. If overloading occurs, move one or more ports to a different trunk in the
group.

To change the load balancing settings:

1. Click a Trunk Group option to place a port into a specific trunk group.

2. Continue to assign ports to trunk groups as necessary.

3. When finished, click Submit.

Fairness and Prioritization

The concept of "f airness" is based on the principl e of e nsuri ng f air device a ccess and
communication across all dev ices i n a storage sy stem. The swit ch in corporates fai rness and
prioritization through Vixel’s InSpeed technology and Automatic Trunking and Load Balancing
functionality. In cooperation with each other, these features ensure even and equal access
through multiple links fairly–effectively multiplying bandwidth.

Device prioritization can be achieved using Load Balancing and assigning only a specific device
port to a particular cascade. This ensures a specific device will always have a dedicated trunk.

Port Utilization and Health

Port utilization measures the amount of traffic passing into a port over a period of time. For
example, if an initiator is transm itting data to a tar get, the initiato r port displa ys a port utilization
value (%) while the target port does not. If the same initiator is receiving data from the target,
the target port displays a port utilization value (%) while the initiator port displays does not.

This part of the web page displays each port number, the port’s current health status, and a
vertical bar indicating the port utilization.

A port number is displayed in one of three colors depending on the port’s current health:

Port utilization is measured by a vertical bar that moves upwards as utilization increases. The
vertical bar has the three distinct levels of utilization:

Power Supply #1 OK (green)–the po wer su pply unit is working pr operly.

Not Present (yello w)–the po wer su pply/fa n modu le has been removed.
Fault (red)–the power supp ly unit ha s stoppe d operatin g. Verify that the
power sup ply/f an modu le is p rope rly se ated in the sw itch.

Power Supply #2 OK (green)–the po wer su pply unit is working pr operly.

Not Present (yello w)–the po wer su pply/fa n modu le has been removed.
Fault (red)–the power supp ly unit ha s stoppe d operatin g. Verify that the
power sup ply/f an modu le is p rope rly se ated in the sw itch.

Tip: Rolling the mouse cu rsor over the port num be r dis play s the cur ren t po rt s tate .

port, and attach the other end to the switch’s DB-9 serial port.

2. Open a terminal session through a serial terminal emulation program (such as
HyperTer minal®) with the appropriate serial port (for example, COM1) and the following
serial port parameters:

• Bits per second: 19200

• Data bits: 8

•Parity: None

•Stop bits: 1

• Flow control: None

3. If using HyperTerminal, press E

NTER to receive a prompt.

4. If using the tip command on a UNIX workstation, do the following:

APPENDIX E Glossary

AL_PA or Arbitrated
Loop Physical Address

A one-byte valu e used t o i denti fy a por t in a n Ar bi trated Lo op to po logy. The
value of the AL_PA correspo nds to bits 7:0 of the 24-bit Native Addr ess
Identifier.

Arbitration The process of selecting one respondent from a group requesting service at

the same time.

Close (CLS) An Arbitrated Loop protocol used to terminate a loop circuit.
Current Fill Word The fill word that the Loop Port State Machine uses when a fill word is to be

transmitted.

Duplex Cable Two fibers in one cable suitable for duplex transmission.
Fiber Optics Light transmission through optical fibers for communication or signaling
Fibre Channel Fi bre Channel is a data transfer interface technology that maps several

common transp ort proto cols in cludi ng IP an d SCSI , al low ing it to me rge
high-speed I/O and netwo rking fun ction ality in a sing le conne ctivity
technology. Fibre channel is an open standard as defined by ANSI and OSI
standards and operates over copper and fiber optic cabling at distances of up
to 10 Kilomete rs. It is un ique in its su ppo rt of mult ipl e inte rop erable
topologies inclu d ing point-to-point, ar bit rated-loop and switchin g and it offers
several qualities of s ervi ce for n etwor k op timiz at ion. W ith its large pa cket
sizes, Fibre Channel is ide al for storage, video, graphic and mass data tr ansf er
applications.

LED Light-Emitting Diode. A s tatus indicat or on a switch.
Gb/s Gigabits per secon d.
Node An entity with one or mo re N _Ports or NL_Ports.
Open (OPN) An Arbitrated Loop protocol used to e stabl ish a loop circ uit.
Protocol A data transmission convention which may include timing, control, formatting,

error detection wit h cor rectio n and d ata repre senta tion .

SCSI Small Computer System Interface. Standard interface for storage modules.
SFP Small Form-Factor Pluggable transceiver. These transceivers are fully

compliant with FC- PI and MSA st andar ds and occ upy less than half the board
space of the existing GBIC products.

Topology The logical and/or physical arrangement of stations on a network. Fibre

Channel topologies include point -to-po int, Arbitrated Loop, a nd switche d
fabric.

Transceiver A device that converts one form of signaling to another for both transmission

and reception. SFPs and GBICs are transceivers.
