Q-Logic 59229-05 A, 9100 manual Planning, Devices

2 Planning

Consider the following when planning a fabric:

Devices

Device Access

Performance

Feature Licensing

Multiple Chassis Fabrics

Switch Services

Internet Protocol Support

Security

Fabric Management

Devices

When planning a fabric, consider the following:

The number of devices and the anticipated demand. This will determine the number of ports that are needed and the number of switches.

The transmission speeds of your HBAs and SFPs. The SFP ports support 1-Gbps, 2-Gbps, and 4-Gbps transmission speeds depending on the SFP. 8-Gbps I/O blades also support 8-Gbps.

NOTE:

Setting an SFP port to 1-Gbps that has an 8-Gbps SFP transceiver will down the port.

The distribution of target and initiator devices. An F_Port supports a single device. An FL_Port can support up to 126 devices in an arbitrated loop.
