EMULEX MODEL 375 SAN STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT Figure 3-14: Single switch zoning configuration 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.
EMULEX MODEL 375 SAN STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 3. Click Submit. Figure 3-16: Ports in Multiple Zones on the One-Step Zoning page 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. Note: To ensure zone integrity when configuring multiple switch zoning, you must implement AL_PA zoning through the Command Line Interface (CLI).
EMULEX MODEL 375 SAN STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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. Switch B Switch A Figure 3-18: Zones Coordinated on Multiple Switches 3. Ensure that the Zoning Active check box is selected for both switches.
EMULEX MODEL 375 SAN 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.
EMULEX MODEL 375 SAN 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. String Cascades A string cascade connects multiple switches (up to three switches maximum) together in a "daisychained" configuration.
EMULEX MODEL 375 SAN 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. Figure 3-22 is an example of Automatic Trunking.
EMULEX MODEL 375 SAN 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 3-23: Advanced Functions: 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.
EMULEX MODEL 375 SAN STORAGE SWITCH USER ’S GUIDE CHAPTER 3: SWITCH MANAGEMENT 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.
EMULEX MODEL 375 SAN 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.
EMULEX MODEL 375 SAN 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.
EMULEX MODEL 375 SAN 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.
EMULEX MODEL 375 SAN 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.
