Dell Brocade 1020 Brocade Adapters Installation and Reference Manual - Page 58

1 Adapter features Before enabling trunking, consider the following requirements: - When trunking is enabled, a trunked logical port (Port 0) is created and reported per HBA or Fabric Adapter port configured in HBA mode. Most BCU commands are applicable in this logical port's context only. - When configuring Fabric Zones and LUN Masking for Storage, use the PWWN for adapter port 0. - Both adapter ports should be connected to the same port group on the switch. - Only two ports on the same adapter can participate in trunking and both of these should be operating at the same speed. - N_Port Trunking is supported on dual port HBA and Fabric Adapter models only. - To enable or disable trunking on the adapter, you must perform configuration tasks on both the switch using Fabric OS commands, as well as the adapter using BCU commands and HCM. Refer to the Brocade Fabric OS Administrator's Guide and Brocade Adapters Administrator's Guide for details. • Server Application Optimization (SAO). When used with Brocade storage fabrics with enabled SAO licensing, Brocade HBAs and Fabric Adapter ports configured in HBA mode can use advanced Adaptive Networking features, such as QoS, designed to ensure Service Level Agreements (SLAs) in dynamic or unpredictable enterprise-class virtual server environments with mixed-SLA workloads. • End-to-end link beaconing between an HBA port or Fabric Adapter port configured in HBA mode and switch port to which it connects. (Requires Brocade Fabric OS 6.3x or above.) • Boot over SAN. This feature provides the ability to boot the host operating system from a boot device located somewhere on the SAN instead of the host's local disk or direct-attached Fibre Channel storage. Specifically, this "boot device" is a logical unit number (LUN) located on a storage device. Booting from direct-attached Fibre Channel storage is also supported. • Fabric-based boot LUN discovery, a feature that allows the host to obtain boot LUN information from the fabric zone database. NOTE This feature is not available for direct-attached targets. • Support for Hyper-V. Hyper-V consolidates multiple server roles as separate virtual machines (VMs) using the Windows Server 2008 operating system and provides integrated management tools to manage both physical and virtual resources. • Support for Windows Preinstallation Environment (WinPE), a minimal operating system with limited services for Windows Server or Windows Vista used for unattended deployment of workstations and servers. WinPE is designed for use as a standalone preinstallation environment and as a component of other setup and recovery technologies. WinPE is supported by Brocade Windows 2008 adapter drivers. • Support for Windows Server Core, a minimal server option for Windows Server 2008 operating systems that provides a low-maintenance server environment with limited functionality. All configuration and maintenance is done through command line interface windows or by connecting to a system remotely through a management application. Windows Server Core is supported by Windows Server 2008 adapter drivers. • Support for MSI-X, an extended version of Message Signaled Interrupts (MSI), defined in the PCI 3.0 specification. MSI-X helps improve overall system performance by contributing to lower interrupt latency and improved utilization of the host CPU. MSI-X is supported by Linux RHEL 5, RHEL 6, SLES 10, SLES 11, Windows 2008, and ESX Server 4.0, 4.1, and 5.0. 30 Brocade Adapters Installation and Reference Manual 53-1002144-01
