SysKonnect SK-9Exx/9Sxx Gigabit Ethernet Server Adapters
5 Software Features
Operating System Support
The drivers for the SysKonnect SK-9Exx/9Sxx Gigabit Ethernet Server Adapter Family support the
following operating systems:
• Windows NT 4.0, Windows 98 Second Edition, Windows Millennium Edition,
Windows 2000, Windows XP, and Windows Server 2003
• Linux kernel 2.4.13 and higher stable versions
The latest version of all available network drivers can be downloaded from the SysKonnect web site
(see section “Additional Documentation and Updates”).
High Performance
The adapters of the SysKonnect SK-9Exx/9Sxx Gigabit Ethernet Server Adapter Family are high
performance and highly reliable adapters.
TCP, UDP and IP Checksum Calculation
The SysKonnect SK-9Exx/9Sxx Adapter supports the calculation of TCP, UDP, and IP checksums.
These calculations are integrated in the hardware of the Gigabit Ethernet adapter. The checksums
are calculated without time loss by the MAC controller for both receive and transmit path. This im-
proves the overall performance of the system and shifts these CPU-intensive tasks away from the
host CPU.
Jumbo Frames
The SysKonnect SK-9Exx/9Sxx Gigabit Ethernet Server Adapter Family supports 9014 Byte Jumbo
frames. It is tested according to the prevailing standard and switches on the market.
TCP Segmentation (Large Send Off-Load)
TCP Segmentation that is handled by the SysKonnect SK-9Exx/9Sxx Adapter itself reduces CPU
load significantly. This provides high throughput for superior network performance and improves ap-
plication response.
Dynamic Interrupt Moderation
If the network is running at gigabit speed and small packets are being transferred, there may in ex-
treme cases be more than 100,000 interrupts per second. To reduce the load on the CPU, the Giga-
bit Ethernet adapters can use Interrupt Moderation to group these interrupts so that several data
packets can be handled per interrupt.
For more information, refer to the White Paper “SK-NET GE Gigabit Ethernet Server Adapter”,
which can be found on the installation CD-ROM and on our web site.
Promiscuous Mode / Multicast Support
The SysKonnect SK-9Exx/9Sxx Gigabit Ethernet Server Adapter Family supports Promiscuous
Mode for analyzers. By default, the promiscuous mode is turned off. In addition, the adapter sup-
ports multicast for special applications, which use multicast addresses.
