Remote Fabric N_Port ID Virtualization Element Manager Application Physical Planning Considerations 5 Intrepid 10000 Director LIMs contain two scalable packet processors, each supporting an optical paddle pair. Each paddle pair provides 16 ports (1.0625 or 2.12500 Gbps operation), four ports (10.2000 Gbps operation), or ten ports (mixed data rate operation). A minimal BB_Credit buffer pool is allocated among all paddle-pair ports that allows a 1.0625 or 2.12500 Gbps port to be set to 60 BB_Credits and a 10.2000 Gbps port to be set to 360 BB_Credits. With the remote fabric feature installed and enabled, the buffer pool is increased and each paddle pair is allocated a maximum of 1,373 BB_Credits. Feature enablement allows a long-link 1.0625 or 2.12500 Gbps port to be set to 1133 BB_Credits and a long-link 10.2000 Gbps port to be set to 1085 BB_Credits. This feature is provided only for the Intrepid 10000 Director. NPIV is a feature that allows a single physical port to support up to 256 virtual Fibre Channel addresses. A virtual node port (NV_Port) retains full N_Port capabilities and can register for full fabric services. However, simultaneous loop device operation (NL_Port) and NPIV operation (NV_Port) is not allowed on the same physical port. This feature is beneficial in mainframe environments where multiple partitions share the same physical channel and port connection. The Element Manager feature allows director or fabric switch management through an Element Manager application GUI. A director or switch is delivered with the application enabled for a 31-day grace period. Before grace period expiration, the application must be reactivated and enabled through a PFE key. During the grace period, a No Feature Key dialog box appears when the Element Manager application is accessed. Click OK to close the dialog box and open the application. In addition, the message Element Manager license key has not been installed - Please follow up instructions to update permanent key appears splashed across views, indicating the Element Manager PFE key must be installed.
