Fabric Manager Users Guide, Version 6.1, Revision A - QLogic

4–Virtual Fabrics
Configuration
• QLogic SDR Host Channel Adapter: 4
• QLogic DDR Host Channel Adapter (TrueScale): 4
• SDR PCI-X (Tavor) Host Channel Adapter: 64
• DDR PCIe dual port (Arbel) Host Channel Adapter: 64
• DDR PCIe single port (Sinai) Host Channel Adapter: 64
• DDR Connect-X Host Channel Adapter: 128
• I9K SWE0:8, Port 0: 8, Port 1-24: 32
Given the listed capabilities, users must be especially careful about how a Switch
Port 0 is included in many vFabrics. To avoid specifying Switch Port 0 in too many
vFabrics, check which include the following:
• SWE0
• SW
• All
• Explicit specification of a switch by PortGuid, NodeGuid or NodeDesc.
In a typical customer configuration, Switch Port 0 only needs to be part of the
admin or default vFabric, for example, PKey 0xffff.
When using QLogic Host Channel Adapters, any given Channel Adapter port
cannot be in more than four secure VirtualFabrics.
When using non-secure VirtualFabrics, the QLogic Fabric Manager may
consolidate PKeys so that a configuration is valid that contains more vFabrics
than the PKey capability.
For secure VirtualFabrics, the PKey is programmed in both the Host Channel
Adapter and its neighboring switch port, in this case the number of PKeys the
Host Channel Adapter can be in is the lesser of the PKey capabilities of the Host
Channel Adapter and the neighboring switch port.
Table 4-2 lists the parameters and their descriptions for the DeviceGroup
subsection under the DeviceGroups section.
