2 Planning Consider the following when planning a fabric: • Devices, page 19 • Device access, page 19 • Performance, page 20 • Feature licenses, page 21 • Multiple switch fabrics, page 21 • Switch services, page 22 • Fabric security, page 23 • Fabric management, page 26 Devices When planning a fabric, consider the number of devices and the anticipated demand. This will determine the number of ports that are needed and in turn the number of switches. Consider the transmission speeds of your HBAs and SFPs. The switch supports 2-Gb/s, 4-Gb/s, and 8-Gb/s transmission speeds. Consider also the distribution of targets and initiators. An F_Port supports a single device. An FL_Port can support up to 126 devices in an arbitrated loop. Device access Consider device access needs within the fabric. Access is controlled by the use of zoning. Some zoning strategies include the following: • Separate devices by operating system. • Separate devices that have no need to communicate with other devices in the fabric or have classified data. • Separate devices into department, administrative, or other functional group. • Reserve a path and its bandwidth from one port to another. Zoning divides the fabric for purposes of controlling discovery and inbound traffic. A zone is a named group of ports or devices. Members of the same zone can communicate with each other and transmit outside the zone, but cannot receive inbound traffic from outside the zone. Zoning is hardware-enforced only when a port/device is a member of no more than eight zones whose combined membership does not exceed 64. If this condition is not satisfied, that port behaves as a soft zone member. You can assign ports/devices to a zone individually or as a group by creating an alias. A zone can be a component of more than one zone set. Several zone sets can be defined for a fabric, but only one zone set can be active at one time. The active zone set determines the current fabric zoning. 8/20q Fibre Channel Switch installation and reference guide 19

Devices

When planning a fabric, consider the number of devices and the anticipated demand. This will determine

the number of ports that are needed and in turn the number of switches.

Consider the transmission speeds of your HBAs and SFPs. The switch supports 2-Gb/s, 4-Gb/s, and

8-Gb/s transmission speeds.

Consider also the distribution of targets and initiators. An F_Port supports a single device. An FL_Port can

support up to 126 devices in an arbitrated loop.

Device access

Consider device access needs within the fabric. Access is controlled by the use of zoning. Some zoning

strategies include the following:

•

Separate devices by operating system.

•

Separate devices that have no need to communicate with other devices in the fabric or have classified

data.

•

Separate devices into department, administrative, or other functional group.

•

Reserve a path and its bandwidth from one port to another.

Zoning divides the fabric for purposes of controlling discovery and inbound traffic. A zone is a named

group of ports or devices. Members of the same zone can communicate with each other and transmit

outside the zone, but cannot receive inbound traffic from outside the zone. Zoning is hardware-enforced

only when a port/device is a member of no more than eight zones whose combined membership does not

exceed 64. If this condition is not satisfied, that port behaves as a soft zone member. You can assign

ports/devices to a zone individually or as a group by creating an alias.

A zone can be a component of more than one zone set. Several zone sets can be defined for a fabric, but

only one zone set can be active at one time. The active zone set determines the current fabric zoning.
