• Supports PCI Express specifications Gen2 (PCI Base Specification 2.0) and Gen1 (PCI Base
Specification 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 values
All Brocade HBAs share a common PCI Vendor ID (VID) value to allow drivers and BIOS to recognize
them 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 host
adapter variants. You can locate PCI device, vendor, and subsystem IDs for the installed Fibre
Channel HBA through your host’s operating system tools. For example, if using Windows, use the
following steps.
1. Access the Device Manager
2. Open the Properties dialog box for the HBA by right-clicking the HBA and selecting Properties
from the shortcut menu.
3. Select the Details and Driver tabs to locate specific values.
