A zoning database is maintained on each switch. Table 3 describes the zoning database limits, excluding the active zone set. Table 3 Zoning database limits Limit Description MaxZoneSets Maximum number of zone sets (256). MaxZones Maximum number of zones (2,000). MaxAliases Maximum number of aliases (2,500). MaxTotalMembers Maximum number of zone and alias members (10,000) that can be stored in the zoning database. Each instance of a zone member or alias member counts toward this maximum. MaxZonesInZoneSets Maximum number of zones that are components of zone sets (2,000), excluding the orphan zone set. Each instance of a zone in a zone set counts toward this maximum. MaxMembersPerZone Maximum number of members in a zone (2,000). MaxMembersPerAlias Maximum number of members in an alias (2,000) Performance The 8/20q Fibre Channel Switch supports class 2 and class 3 Fibre Channel service at transmission rates of 8-Gb/s with a maximum frame size of 2,148 bytes. Related performance characteristics include the following: • Distance, page 20 • Bandwidth, page 20 • Latency, page 21 Distance Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter. For more information about cable types and transceivers, see "Technical specifications" on page 55. Each Fibre Channel port is supported by a data buffer with a 16 credit capacity; that is, 16 maximum sized frames. For fibre optic cables, this enables full bandwidth over approximately 3 kilometers at 8 Gb/s (4.8 credits/km). Bandwidth Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A Fibre Channel port can transmit or receive at nominal rates of 8 Gb/s, 4 Gb/s, or 2 Gb/s depending on the device to which it is connected. This corresponds to full duplex bandwidth values of 1,700 MB, 850 MB, and 424 MB respectively. Multiple source ports can transmit to the same destination port if the destination bandwidth is greater than or equal to the combined source bandwidth. For example, two 4 Gb/s source ports can transmit to one 8 Gb/s destination port. Similarly, one source port can feed multiple destination ports if the combined destination bandwidth is greater than or equal to the source bandwidth. In multiple switch fabrics, each link contributes up to 1,700 MB of bandwidth between those switches, depending on the speed of the link. When additional bandwidth is needed between devices, increase the number of links between the connecting switches. The switch guarantees in-order delivery with any number of links. 20

Consider the physical distribution of devices and switches in the fabric. Choose SFP transceivers that are

compatible with the cable type, distance, Fibre Channel revision level, and the device host bus adapter.

For more information about cable types and transceivers, see ”

Each Fibre Channel port is supported by a data buffer with a 16 credit capacity; that is, 16 maximum sized

frames. For fibre optic cables, this enables full bandwidth over approximately 3 kilometers at 8 Gb/s (4.8

credits/km).

Bandwidth is a measure of the volume of data that can be transmitted at a given transmission rate. A Fibre

Channel port can transmit or receive at nominal rates of 8 Gb/s, 4 Gb/s, or 2 Gb/s depending on the

device to which it is connected. This corresponds to full duplex bandwidth values of 1,700 MB, 850 MB,

and 424 MB respectively. Multiple source ports can transmit to the same destination port if the destination

bandwidth is greater than or equal to the combined source bandwidth. For example, two 4 Gb/s source

ports can transmit to one 8 Gb/s destination port. Similarly, one source port can feed multiple destination

ports if the combined destination bandwidth is greater than or equal to the source bandwidth.

In multiple switch fabrics, each link contributes up to 1,700 MB of bandwidth between those switches,

depending on the speed of the link. When additional bandwidth is needed between devices, increase the

number of links between the connecting switches. The switch guarantees in-order delivery with any number
