A zoning database is maintained on each switch. Table 3 describes the zoning database limits, excluding
the active zone set.
Performance
The SN6000 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 21
• Latency, page 22
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.
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).
With the optional Enterprise Fabric Management Suite application, longer distances can be spanned at
full bandwidth on SFP ports by extending credits to G_Ports, F_Ports, and E_Ports. Each port can donate 15
credits to a pool from which a recipient port can borrow. However, SFP ports can borrow only from other
SFP ports. XPAK ports cannot borrow or donate credits. The recipient port also loses a credit in the process.
For example, you can configure an SFP recipient port to borrow 15 credits from one donor port for a total
of 30 credits (15+15=30). For more information about Enterprise Fabric Management Suite, see
”Enterprise Fabric Management Suite” (page 18).
Table 4 describes the possible distances for a port with 30 credits as an example.
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)
Table 4 Extended credit distances
Transmission Speed Range for 30 Credits
1 Gb/s 50 kilometers (30÷0.6)
2 Gb/s 25 kilometers (30÷1.2)
4 Gb/s 12 kilometers (30÷2.4)
8 Gb/s 6 kilometers (30÷4.8)
