VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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 the Zoning Active check box is selected for both switches.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 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.
VIXEL INSPEED™ SAN STORAGE SWITCH MODEL 375 USER ’S GUIDE CHAPTER 3 SWITCH MANAGEMENT Load Balancing Load balancing builds on the Automatic Trunking functionality by specifying the path that the data uses to flow between multiple switches. Users can manage the switch’s aggregate bandwidth by manually distributing traffic across multiple cascade ports as shown below.
