INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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. Port Information The following settings are available.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Setting Description Port Test Before Insertion This policy ensures that a device on a port is a valid, standardscompliant 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Switch Firmware Files This section displays the current and alternate firmware versions, enables users to select which firmware version to run the next time the switch is reset, and provides a means to load new firmware on the switch.

INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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 status. See the descriptions in the following table: Color Description Down (red) One or more ports have been selected, zoning has been activated, but hardware has caused a failure.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Single-Switch Zoning The simplest zoning configuration is to place devices into separate (non-overlapping) zones. Only the devices within each zone can communicate with one another. Examples of these configurations are shown in Figure 3-13, Figure 3-14, and Figure 3-15.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Figure 3-15: Non-overlapping zones in a combined Disk and Tape Storage System Adding Devices to Multiple Zones Another zoning configuration enables users to place devices in more than one zone (overlapping zones). Overlapping zoning enables devices to be shared between hosts, which is important for backup and recovery purposes. Figure 3-16 and Figure 3-17 demonstrate this zoning configuration.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Figure 3-17: Overlapping zones in a Tape Storage System To add storage devices to multiple zones: 1. Select the appropriate zones for each port. 2. Ensure that the Zoning Active check box is selected. 3. Click Submit. Multiple Switch Zoning While not common in embedded storage systems, zoning can also be configured across multiple switches.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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).
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT To assign ports to trunk groups: 1. Click Advanced Functions > Automatic Trunking. 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Switch Information Current status is provided for the following items. Item Status Indicators Switch Status • OK (green)–the switch unit is operating normally. • Fault (red)–one or more of the ports has failed, the internal temperature has exceeded acceptable levels, or another error has occurred. Errors appear in the event log.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Viewing the Event Log The Event Log contains a list of up to 3000 event log messages generated by the switch. The Switch Event Log page displays the event log messages with each message containing the following information: • Event Number – the number assigned to that specific event in the log. • Event Date and Time – the date and time when the event was recorded in the log.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Viewing Port Information The Port Information page displays the Smart Settings, Serial ID (SID), and AL_PAs currently assigned to each port. Initiator AL_PAs are highlighted in blue to differentiate them from target AL_PAs. Note: The Initiator AL_PA information can be used to easily identify attached devices when configuring load balancing. To view port information: Click Port > Information.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Viewing Port Utilization 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.
INSPEED MODEL 370 EMBEDDED STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Viewing Port Diagnostics This page displays diagnostic information pertaining to each port in the switch. Use the information provided on this page to diagnose abnormally high error counts on a particular port. To view the current diagnostic settings: Click Advanced Functions > Diagnostics > Port.
