For transmit interrupts AIC is not supported To disable AIC and set the interrupt delay duration to a constant value see the following section Setting the Interrupt Delay Duration to a Constant Value The interrupt delay duration can be set to a constant value for both receive and transmit interrupts The possible interrupt delay duration values are 0 to 96 microseconds in 8 microsecond increments For receive interrupts disable AIC since it is enabled by default and set the interrupt delay duration using ethtool For example to disable AIC and set the constant RX interrupt delay to 8 microseconds run ethtool C eth lt N gt adaptive rx off rx usec 8 where eth lt N gt is the number of the Ethernet interface you are working on If your application requires low or predictive latency Emulex recommends that you turn off AIC and set rx usecs to 0 Emulex Drivers for Linux User Manual P009417 02A Rev A DE EMULEX 3 Configuration 58 Network Performance Tuning For transmit interrupts the default interrupt delay duration is 96 microseconds You can change this value using ethtool For example to set the TX interrupt delay to 64 microseconds run ethtool C eth lt N gt tx usec 64 where eth lt N gt is the number of the Ethernet interface you are working on Receive Side Scaling RSS Distributing the incoming traffic across several receive rings with separate interrupt vectors helps to distribute the receive proces

77. The maximum number of LUNs supported on each driver port is 256 The maximum number of targets supported for each driver port is 255 The maximum number of driver ports in one zone is 64 This limit is based on the system s ability to recover from link events within the time constraints of the default timers The NPIV use cases that involve virtual server environment include associating a VPort with a virtual machine and placing the virtual machine in its own zone This results in one VPort per zone In the case of load balanced environments this can increase typically to two VPorts per virtual machine to a practical limit of something far less than 50 In the NPIV cases not related to virtual server environments zoning is typically initiator zoning again resulting in one VPort or a low number of VPorts in the case of load balancing within a given zone If there are too many VPorts within a single zone expected behavior includes devices being lost after link events The minimum lifetime of a VPort is 60 seconds There is an unenforced limit of 60 seconds between the creation of a VPort and the deletion of the same VPort VPorts are designed to live for a long time in the system and the creation of VPorts is asynchronous This means that a VPort might not be finished with FC or SCSI discovery when the command to create a VPort is finished Emulex Drivers for Linux User Manual P009417 02A Rev A P 3 Configuration 50 gt G EMULEX DHCH
