OVERVIEW
The InSpeed Model 350 Embedded Storage Switch is a 12-port, non-blocking switch designed for storage system suppliers who want to improve the reliability, availability, and serviceability (RAS) and performance of their systems.
Enclosed in a 1U, half-rack form factor enclosure, the switch is built around the InSpeed SOC 320 and is controlled by firmware loaded into the on-board Flash.
The switch is designed as a central interconnect following the ANSI FC-AL standard. Devices are connected to the switch through Small Form-factor Pluggable (SFP) transceivers and cables. Each attached node has 1 or 2 Gigabits per second (Gb/s) of Fibre Channel bandwidth. The switch operates at full switching bandwidth that reaches wire speeds of 4 Gb/s per port and up to 48 Gb/s of aggregate bandwidth.
Complete switch configuration and management is available through the intuitive, graphical-based Web Manager interface. A variety of network configurations are easily established using the switch’s Port Smart Settings, One-Step Zoning, Automatic Trunking, and Load Balancing features. In addition, the switch features granular change notification management, retained system configuration parameters, and a Command Line Interface (CLI) for advanced users.

• Half-rack, 1U size for easy installation (optional 19" rack-mounting kits available).
• Fibre Channel ANSI Standards Compliance
INSPEED™ TECHNOLOGY
InSpeed technology is an advanced switching architecture that couples a non-blocking crossbar switch with a unique switch port logic and per-port SERDES. This results in the industry’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 switch’s router to send data directly from one port to another, allowing for multiple, simultaneous conversations between ports – effectively multiplying bandwidth. InSpeed™ provides the same performance as complex fabric switches that support FC-SW2.
SWITCH APPLICATIONS
The InSpeed Model 350 Embedded Storage Switch is ideal for embedded applications in storage or tape library systems, where improvements to the reliability, availability, and serviceability (RAS) and performance of systems is critical. The following sections provide examples of these applications.

ART NUMBER 00041410-002 REV. B
SFP COMPATIBILITY
SFPs are “hot-pluggable” into the switch, which allows host computers, servers, 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 Emulex’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 Change Notification on Insertion policy is enabled, plugging an SFP into the switch will automatically send an F7 Initialization notification to indicate the device is ready to begin initialization.
Caution: Forcing an SFP into a port may damage the SFP and/or port.
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,
and toward the side of the SFP with the tag.
If the SFP has a small plastic slider on the top or bottom
the slider and hold while pulling out the SFP.
If the SFP has a bale (small metal clasp)
and pull the bale.
remove the cable from the SFP and then pull the removal tag outward
, remove the cable from the SFP and then push in
, remove the cable from the SFP and then unlatch, pivot,
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 operational and set to the same speed.

ART NUMBER 00041410-002 REV. B
BOOTING THE SWITCH AND ATTACHED DEVICES
The following procedure is recommended when booting the switch and attached devices. Before powering on the switch and attached devices, 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 attached devices:
1. Power on the storage devices (such as disk or tape drives).
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 and runs Power-On Self-Test (POST) diagnostics to verify the fundamental integrity of the switch ports. All switch LEDs turn on (LEDs illuminate). Then, excluding the Ethernet Link and Power LEDs, the LEDs turn off (LEDs extinguish). Once the switch is operational, the LEDs display current status as described in “Switch LEDs” on page 9.
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.
4. Power on any other switches connected to the SAN.
5. For certain applications, switch configuration must be completed before 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 or storage controllers.
The network initializes.
Note: FC-AL compatible nodes must perform initialization procedures upon power-up in
order to function properly. It is the responsibility of the Fibre Channel driver software on FC-AL nodes to perform this initialization.
7. Check all port LEDs.
The network should be fully operational at this point. However, it is appropriate to ensure that 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.

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 that 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.
Note: Changing the Smart Setting of a port may affect the performance or behavior of the system.
Depending on the implementation, some Smart Settings are more appropriate than others.
Initiator or Target
This Smart Setting is the default setting 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 received by the initiator.
This Smart Setting is appropriate for embedded storage controllers and external Host Bus Adaptors (HBAs) or servers with installed HBAs.
Target with Stealth
This Smart Setting is used when connecting embedded storage devices, like JBODs, SBODs, tape drives, or external RAID systems (JBODs, SBODs, or tape libraries). When a port is set to this Smart Setting, change notifications are sent to other devices, but change notifications 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 InSpeed Model 350 Embedded Storage Switch to 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 option, consider the following:
• Cascade ports of like number should be connected together. For example, connect port 1 of Switch A to port 1 of Switch B, connect port 2 of Switch B to port 2 of Switch C, and so 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.
EMULEX CORPORATION 29
P
ART NUMBER 00041410-002 REV. B
• When configuring multiple switches with a single cascade, use alternating ports. For example, connect the second switch using ports 1 and the third using ports 2 as shown in Figure 3-10.
Figure 3-10: Alternating Ports for Single Cascades
To assign a Smart Setting to one or more ports:
1. Select the appropriate Smart Setting from the list box.
2. From the list of port numbers, select the ports that will use the selected Smart Setting under the Assign heading.
3. Once completed, click Submit to save the settings.

Smart Setting Assignments
The Smart Settings are based on several port settings and policies grouped into the following categories:
• Port Information
• Pre-Insertion Testing
• Change Notifications
•Port Recovery
• Diagnostics
These settings can be adjusted on custom Smart Settings; however, these settings are fixed on the default Smart Settings.
EMULEX CORPORATION 31

ART NUMBER 00041410-002 REV. B
Port Information
The following settings are available.
Setting Description
Smart Setting Name Displays the name of the Smart Setting. The Smart Setting name will
automatically appear in the text box when selected in the scroll menu.
Smart Setting Type The topology among switches for a port. Options include:
• Initiator or Target Port – the default setting. Should be used when there are no links between switches.
• Tree Cascade – designates the port as a tree cascade port. Use this setting when connecting multiple switches together in a tree cascade configuration. Under most conditions, this setting will result in acceptable performance.
• String Cascade 1 through String Cascade 4 – designates the string cascade to which a port is assigned. String cascades maintain fairness when two or more InSpeed-based storage switches are serially cascaded. Switch performance may be lower when compared to a tree cascade configuration.
Pre-Insertion Testing
The following settings are available.
Setting Description
Enable Policies/Smart Insertion
Port Test Before Insertion This policy ensures that a device on a port is a valid, standards-
This policy is the default operating mode for all ports and determines what the switch looks for prior to allowing a port to insert into a zone. When the policy is enabled, an external device is sent an F7 Initialization notification by the switch until an F7 Initialization notification is received from the device. Once an F7 Initialization notification is received, the port is inserted in the zone. 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 frequency and amplitude, the port will be allowed in the zone.
compliant participant before allowing the device to be inserted into a zone. The device must meet all of the FC-AL requirements along with going 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 complete, the device can be inserted. This process ensures that a bad device is not allowed into the zone.
EMULEX CORPORATION 32
P
ART NUMBER 00041410-002 REV. B
Change Notifications
The following settings are available.
Setting Description
Stealth Intelligent Change Manager
Change Notification on Insertion
Stealth Intelligent Change Manager provides stability and control over change notification disruptions on a port basis. Options include:
• Off: No Change Protection – no Stealth Intelligent Change Manager control.
• Initiator: Only Receive Changes – devices attached to the port can receive change notifications but will not propagate change notifications generated by that port to other ports.
• Target: Only Send Changes – propagates change notifications generated by the port to other ports but will not allow devices attached to the port to receive change notifications from other ports.
• Switch-Switch: Send and Receive Changes – allows change notifications to propagate between switches.
• Custom-1 – Note: This setting should not be used unless directed to do so by a customer service representative.
The switch normally operates under the condition that when a device is inserted onto the network, a change notification is generated. However, this condition is not always true when connecting hubs or switches together. In some instances, it is possible to connect two zones together without the zones realizing that multiple AL_PAs exist with the same values. When this policy is enabled, the switch always generates a change notification to ensure that the proper system updates are performed. However, when a device is removed (for example, an initiator or target), the removal does not generate a change notification and there are no system updates performed.
Change Notification on Remova
l
This policy is similar to the Change Notification on Insertion policy, except for the change notification being sent when a device is removed rather than inserted. When this policy is enabled, the switch always generates a change notification to ensure that the proper system updates are performed.
EMULEX CORPORATION 33
P
ART NUMBER 00041410-002 REV. B
Port Recovery
The following settings are available.
Setting Description
Bad Device Recovery When a port is already inserted into a zone, the port transforms F8
Failure notifications into F7 Initialization notifications. When this occurs, the port is bypassed and F7 Initialization notifications are allowed in the zone. Once the initialization is complete, the Bad Zone Recovery Policy is operational and prevents a port that continues to transmit F8 Failure notifications from inserting into the zone.
Note: If this policy is disabled while the Bad Zone Recovery policy is
enabled, a zone that does go down will still allow the Bad Zone Recovery policy to reset the zone and allow ports to be
reinserted. When enabled, this policy prevents devices that send F8 Failure notifications from inserting into a zone. The ability to remove devices that generate F8 Failure notifications automatically and instantaneously guarantees continual system operation. When disabled, this policy allows devices that send F8 Failure notifications to insert into a zone and does not consider F8 Failure notifications when determining whether to insert a device or not.
Clear on Stall In situations where the switch is operating in switching mode, some
devices may fall into an operating mode where the device has opened a target but has not released the connection to the target. When this policy is enabled, the switch can detect this condition and automatically recover when this situation arises.
Bypass on No Activity The switch detects the amount of time a data stream has gone
without receiving a comma. The time setting is set to 100 (.001 seconds). When this policy is enabled, the switch bypasses the disruptive port when the threshold is exceeded.
Bypass on Ordered Set Error Ordered Set (OS) errors are detected and counted for each individual
port. When this policy is enabled, a port is bypassed when its OS count exceeds the threshold setting. The threshold setting is based on the number of ordered set errors identified in 10 seconds.
Note: This threshold setting can be adjusted on the Web Manager’s
Advanced Functions Switch Thresholds page.
Bypass on CRC Error Cyclic Redundancy Check (CRC) errors are detected and counted for
each individual port. When this policy is enabled, a port is bypassed when its CRC count exceeds the threshold setting. The threshold setting is based on the number of CRC errors identified in 10 seconds. User intervention is required to return the port into the zone. Recovery methods include replacing the defective component, cycling power to the device on the port, removing and reinserting the bypassed port, or cycling power to the switch.
Note: This threshold setting can be adjusted on the Web Manager’s
Advanced Functions Switch Thresholds page.
EMULEX CORPORATION 34

ART NUMBER 00041410-002 REV. B
Diagnostics
The following settings are available.
Setting Description
Port Control The method for controlling a port. Options include:
• 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.
• extLoopback – removes a port from the network and routes the port's receive signal back through the port's transmitter. Use this mode to isolate a specific zone for troubleshooting or to test a transceiver’s circuitry and attached media from the node 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 frequency of the signal being
received by a port to the internal switch clock. The result of this test allows the determination of how far apart in frequency 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 allow the removal and replacement of a defective part before the defective part begins to affect system performance.

2. Click OK to restore the factory default configuration and reset the switch.
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 zones.)
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 increased security.
• Separate test or maintenance areas from production areas.
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 the grid. Zones 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.
Figure 3-12: One-Step Zoning page
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.
EMULEX CORPORATION 37

Multiple Switch Zoning
While not common in embedded storage systems, zoning can also be configured across multiple switches. The procedure is the same as on a single switch; however, multiple-switch zoning requires
some coordination between the switches.
Note: To ensure zone integrity when configuring multiple switch zoning, you must implement AL_PA
zoning through the Command Line Interface (CLI). See “AL_PA Zoning” on page 43 for additional information.
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 that the Zoning Active check box is selected for both switches.
Caution: Clearing the Zoning Active check box will deactivate all zones, which may degrade
system performance or compromise security.

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 connection between the ports in a zone topology, splitting the switch into multiple unique FC-AL zones. When Hard 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.
Caution: Do not set a Hard Zone for ports in multiple zones or share ports that have the Hard Zone
option set. This will cause errors that do not log an event or display a message.
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.
Figure 3-18: Hard Zoning configuration
To set up Hard Zoning:
1. Determine which ports will reside in each Hard Zone and ensure that the ports are in only one Hard Zone.
2. Under Hard Zone, select the check boxes for the appropriate zones.

AL_PA Zoning
AL_PA zoning is a specific zoning configuration that prevents devices from accessing one another. AL_PA zoning fully ensures that devices will not access each other by blocking a group of devices (using AL_PAs) from communicating with each other; however, AL_PA zoning allows the devices to communicate with devices outside of the group.
AL_PA zoning is only accessible through the Command Line Interface (CLI). Refer to the
InSpeed™ Storage Switch Products’ CLI Reference Guide
for additional information.

Recovering a Bad Zone Automatically
Bad zone recovery policy automatically recovers traffic 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 devices 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.
Note: The Bad Zone Recovery policy is enabled by default. If the Bad Zone Recovery policy is
disabled, use the following instructions to enable this policy for the appropriate zones.
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.

Cascading Switches
When multiple switches are connected, the connecting links between the switches are referred to as "cascades". There are two distinct cascade configurations to consider when 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 cascade before device access is granted. This arbitration method promotes fairness between the switches. However, when compared to tree cascades, string cascades offer less performance due to the increased latency between the switches.
Figure 3-19: String Cascade configuration example
When configuring a switch port for a string cascade, use the String Cascade Smart Setting. To enable the string cascade, go to the Automatic Trunking page. From the Automatic Trunking page, select the Single Cascade option, or place the string cascade into a trunk group. See “Automatic Trunking” on
page 45 for additional information.
To reduce contention and improve performance between initiator traffic and target traffic when using a string cascade configuration, connect the ports of each switch together using the same String Cascade Smart Settings. For example, in Figure 3-19 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 switch connected to additional switches (up to 8 switches maximum). When 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 another, as fairness is not used for tree cascades.
Figure 3-20: Tree Cascade configuration example
When configuring a port for a tree cascade, use the Tree Cascade Smart Setting. To enable the tree cascade, go to the Automatic Trunking page. From the Automatic Trunking page, select the Single Cascade option, or place the tree cascade into a trunk group. See “Automatic Trunking” on page 45 for additional information.

ART NUMBER 00041410-002 REV. B
Automatic Trunking
Multiple links between switches are called “trunks”. Trunks provide higher bandwidth across cascaded switches for systems incorporating multiple initiators. Each trunk 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 3-21 is an example of Automatic Trunking.
Figure 3-21: A
Each trunk is part of a trunk group. A trunk group consists of two or more cascades between two switches, and these cascades must be the lowest numbered ports on both switches. There can only be one trunk group between two switches. Each trunk group contains 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.
Only one of the three following options may be selected for each port.
• Device or Initiator – Select this option to designate a specific port as an initiator or device. The specified port is not assigned to a trunk group. The Device or Initiator option is the default setting.
• Single Cascade – Select this option when connecting two switches with a single cascade. The selected port is not part of a trunk group.
• Trunk Group – Select this option when multiple cascades are connected between two switches. The selected port must be assigned to an available trunk group. Multiple trunk groups appear when two or more ports are assigned to the same string cascade Port Smart Setting (for example, String Cascade - Trunk 1).
Note: Before changing the Port Smart Setting for a particular port assigned to a trunk group, you must
remove that port from the trunk group by selecting the Device or Initiator setting. Remember to click Submit to update the port’s setting.

The Automatic Trunking page appears.
Figure 3-22: Automatic Trunking page
2. Select a trunk group for each port by clicking the appropriate Trunk Group option.
3. When finished making changes, click Submit.
Load Balancing
Load balancing builds on the Automatic Trunking functionality by specifying the path that the data uses to flow between multiple switches. Manage the switch’s aggregate bandwidth by manually distributing traffic across multiple cascade 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 configured differently.
Figure 3-23: Load Balancing Across Multiple Cascade Ports
Note: Cascade ports must be properly configured before load balancing will work.
In Figure 3-23, 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.
EMULEX CORPORATION 46
P
ART NUMBER 00041410-002 REV. B
Note: When tape drives or tape libraries are included in multiple switch configurations incorporating
multiple trunks, place the tape drive or tape library and any devices that access those devices on the secondary (duplicate) trunk, not the primary trunk.
Load balancing configuration settings are available on the Web Manager’s Load Balancing page. Before implementing load balancing on the switch, the automatic trunking settings must be configured. See
“Automatic Trunking” on page 45 for additional information.
To view the Load Balancing page:
Click Advanced Functions > Load Balancing.
Figure 3-24: Load Balancing page
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 identify a specific trunk 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 “fairness” is based on the principle of ensuring fair device access and communication across all devices in a storage system. The switch incorporates fairness and prioritization through 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 that 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 transmitting data to a target, the initiator port displays 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.
Tip: Rolling the mouse cursor over the port number displays the current port state.
A port number is displayed in one of three colors depending on the port’s current health:
Port Color Indication
Green An SFP is inserted into the port and a device is connected to the SFP.
Yellow • Bypassed – The port is bypassed. An SFP may be inserted in the port but
there may not be a device connected to the SFP.
• Loopback – There is no device connected to the port. The transmit and receiver are connected together on the SFP transceiver.
• LIPF8Present – If the switch is receiving an F8 Failure notification, the port is bypassed to allow remaining devices to proceed with initialization.
• Redundant – The port is a failover link in a cascade and is not currently active.
Red • TxFault – Detects an SFP transmitter fault.
• DiagTx – Detects Ordered Sets being transmitted, so traffic cannot be passed through the port.
• DataTimeout – Detects a data timeout fault.
• RxLoss – Detects a loss of received signal amplitude from the device.
• SyncLoss – Detects a loss of word synchronization for a specified time, which may be caused by poor signal strength, intermittent line conditions, and so on.
Gray • Unknown – The port status cannot be determined.
• NoSFP – There is no SFP connector inserted in the port.
Port utilization is measured by a vertical bar that moves upwards as utilization increases. The vertical bar has the three distinct levels of utilization:
Bar Color Indication
Green The port is operating at optimal utilization.
Yellow The port is experiencing periods of heavy traffic.
Red The port has too much traffic on it and is not operating at desired levels. Some
devices should be transferred to other ports to improve port utilization.

The switch must be operated in a clean, dry environment with unrestricted airflow. Air flows in through the cosmetic end and out through the business end (sometimes called the transceiver end or “back-of-box”).
To avoid overheating, maintain a minimum clearance of two inches (50.8 millimeters) on each end of the switch (the cosmetic end and the business end). Allow an adequate amount of space on the top and sides of the switch for proper air ventilation. Do not place the switch on heat-generating surfaces. Operating conditions are listed below.
