If you are upgrading the driver software, start with step : If you update the firmware, you must update the driver software to the same family version. 1. Review system requirements. 2. Insert the PCI Express adapter , Mezzanine Card, or network Daughter Card into your server. 3. Carefully connect the network copper cable(s), fiber cable(s), or direct attach cables 4.

6 Turn off the computer and unplug the power cord. 2. Remove the computer cover and the adapter slot cover from the slot that matches your adapter . 3. Insert the adapter edge connector into the slot and secure the bracket to the chassis. 4. Replace the computer cover, then plug in the power : For information on identifying PCI Express slots that support your Adapters , see your Dell EMC system Drivers and SoftwareWindows* Operating SystemsYou must have administrative rights to the operating system to install the drivers. 1. Download the latest drivers from the support website and transfer them to the system. 2. If the Found New Hardware Wizard screen is displayed, click Cancel. 3. Double-click the downloaded file.

Be sure to select Intel PROSet for : Be sure to select the iSCSI using Data Center Bridging" install option for systems that have an NPAR capable device Linux* Drivers from Source Code 1. Download and expand the base driver tar file. 2. Compile the driver module. 3. Install the module using the modprobe command. 4. Assign an IP address using the ifconfig refer to the Linux section of this Guide for more specific Operating SystemsTo install other drivers, visit the Customer Support web site: PerformanceYou can configure Intel network adapter advanced settings to help optimize server examples below provide guidance for three server usage models: lOptimized for quick response and low latency useful for video, audio, and High Performance Computing Cluster (HPCC) servers lOptimized for throughput useful for data backup/retrieval and file servers lOptimized for CPU utilization useful for application, web, mail, and database serversNOTES.

8 LThe recommendations below are guidelines and should be treated as such. Additional factors such as installed applications, bus type, network topology, and operating system also affect system performance. lThese adjustments should be performed by a highly skilled network administrator. They are not guar-anteed to improve performance. Not all settings shown here may be available through network driver configuration, operating system or system BIOS. Linux users, see the README file in the Linux driver package for Linux-specific performance enhancement details. lWhen using performance test software, refer to the documentation of the application for optimal Optimization lInstall the adapter in an appropriate slot.

9 NOTE: Some PCIe x8 slots are actually configured as x4 slots. These slots have insufficient bandwidth for full line rate with some dual port Devices . The driver can detect this situation and will write the fol-lowing message in the system log: PCI-Express bandwidth available for this card is not sufficient for optimal performance. For optimal performance a x8 PCI-Express slot is required. If this error occurs, mov-ing your adapter to a true x8 slot will resolve the issue. lIn order for an Intel 710 Series network adapter to reach its full potential, you must install it in a PCIe Gen3 x8 slot. Installing it in a shorter slot, or a Gen2 or Gen1 slot, will impact the throughput the adapter can attain.

10 LUse the proper cabling for your device. lEnable Jumbo Packets, if your other network components can also be configured for it. lIncrease the number of TCP and Socket resources from the default value. For Windows based systems, we have not identified system parameters other than the TCP Window Size which significantly impact performance. lIncrease the allocation size of Driver Resources (transmit/receive buffers). However, most TCP traffic patterns work best with the transmit buffer set to its default value, and the receive buffer set to its minimum value. lWhen passing traffic on multiple network ports using an I/O application that runs on most or all of the cores in your system, consider setting the CPU Affinity for that application to fewer cores.
