Intel 10 Gigabit AT Ethernet Server Adapter, Руководство пользователя, Страница: 6 / 165

Installing 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 command.
Optimizing Performance
You can configure Intel network adapter advanced settings to help optimize server performance.
The examples below provide guidance for three server usage models:
l
Optimized for quick response and low latency – useful for video, audio, and High Performance Com-
puting Cluster (HPCC) servers
l
Optimized for throughput – useful for data backup/retrieval and file servers
l
Optimized for CPU utilization – useful for application, web, mail, and database servers
NOTES:
l
The 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.
l
These adjustments should be performed by a highly skilled network administrator. They are
not guaranteed 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.
l
When using performance test software, refer to the documentation of the application for
optimal results.
General Optimization
l
Install the adapter in an appropriate slot.
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 following 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, moving your adapter to a true x8 slot will resolve
the issue.
l
In order for an Intel® X710/XL710 based 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.
l
Use the proper cabling for your device.
l
Enable Jumbo Packets, if your other network components can also be configured for it.
l
Increase the number of TCP and Socket resources from the default value. For Windows based sys-
tems, we have not identified system parameters other than the TCP Window Size which significantly
impact performance.
