The Emulex card uses a firmware-based architecture that allows firmware upgrades without taking the server offline, rebooting, or upgrading the driver. The QLogic cards provide dual-port, 8-Gb/s or 4-Gb/s FC connectivity along with intelligent networking features specific to enterprise class data centers. In addition, QLogic's unified driver model, whereby firmware is bundled with the driver, eliminates potential interoperability issues between the driver and firmware and reduces the number of software components that administrators must mange. The Emulex and QLogic 4-Gb cards are compatible with all ProLiant c-Class and Integrity server blades. The Emulex and QLogic 8-Gb cards are compatible with ProLiant G6 server models but are not compatible with the Integrity servers. The 8-Gb FC HBA cards can also operate at 4-Gb, 2-Gb, and 1-Gb speeds.
