188 Brocade Adapters Installation and Reference Manual53-1002144-01Host Bus Adapters5• Supports PCI Express specifications Gen2 (PCI Base Specification 2.0) and Gen1 (PCI BaseSpecification 1.0, 1.1a, and 1.1).• Operates as an x8 lane DMA bus master at 2.5 GHz, full duplex.• Effective data rate on Gen2 systems is 32 Gbps and on Gen1 systems is 16 Gbps.• On-board flash memory provides BIOS support over the PCI bus.PCI system valuesAll Brocade HBAs share a common PCI Vendor ID (VID) value to allow drivers and BIOS to recognizethem as supported Fibre Channel products. HBAs are also assigned PCI subsystem vendor IDs(SVIDs) and subsystem IDs (SSIDs) to allow drivers and BIOS to distinguish between individual hostadapter variants. You can locate PCI device, vendor, and subsystem IDs for the installed FibreChannel HBA through your host’s operating system tools. For example, if using Windows, use thefollowing steps.1. Access the Device Manager2. Open the Properties dialog box for the HBA by right-clicking the HBA and selecting Propertiesfrom the shortcut menu.3. Select the Details and Driver tabs to locate specific values.Hardware specificationsThe Fibre Channel interface supports features outlined in Table 26.TABLE 26 Supported Fibre Channel featuresFeature DescriptionPort Speeds Brocade 804:Internal ports allow user-selectable orauto-negotiated speeds of 8, 4, 2, or 1 Gbpsper port.Brocade 825 and 815:• An installed 8 Gbps SFP+ allowsuser-selectable or auto-negotiated speeds of8, 4, or 2 Gbps per port.• An installed 4 Gbps SFP allowsuser-selectable or auto-negotiated speeds of4, 2, or 1 Gbps per port.Brocade 425 and 415:• An installed 4 Gbps SFP allowsuser-selectable or auto-negotiated speeds of4, 2, or 1 Gbps per port.• An installed 8 Gbps SFP+ allowsuser-selectable or auto-negotiated speeds of4 or 2 Gbps per port.NOTE: 8 Gbps adapters support 1 Gbps at thedriver level, but not in a BIOS or boot overSAN configuration.SFP transceivers(stand-up adapters)Multimode small form factor pluggable (SFP)
