1.2 Description
Alacritech Accelerators are single-port or multi-port network interface cards (NICs) that
employ Alacritech‘s SLIC Technology architecture, which uses an innovative applica-
tion-specific integrated circuit (ASIC) for protocol processing. Accelerators operate with
Windows Server 2003 or Windows XP Professional x64 Edition operating systems using the Microsoft Scalable Networking Pack.
The SLIC Technology architecture increases server performance and efficiency in two
specific ways:
TCP/IP Protocol processing is offloaded onto the Accelerator, freeing the CPU
for application processing and maximizing throughput
A unique ASIC utilizes an Internet Protocol Processor (IPP), optimized for
TCP/IP protocol processing, which delivers faster performance than general
purpose CPUs
SLIC Technology eliminates the burden of TCP/IP protocol processing on the host
CPU. By offloading protocol processing, SLIC Technology frees the CPU for application processing, boosting both network and server performance.

3.4 Disabling Windows Firewall to Enable TCP Offload
In Windows XP Professional it is necessary to disable Windows Firewall/Internet Connection Sharing to activate the TCP Offload feature on the Accelerators in your system.
Note: By default with Windows XP Professional, the Windows Firewall feature is
turned on. Therefore, TCP Chimney will not function in such a scenario.
The Windows Firewall must be explicitly turned off before TCP Chimney
can function.
Note: By default, the IP NAT and IPsec Policy Agent features are turned on
when certain components such as bridging and routing services are
enabled. Therefore, TCP Chimney will not function in such a scenario.
When the bridging and routing services are disabled, IPNAT is not turned
off. Therefore, TCP Chimney is not re-enabled.
The IP NAT and IPsec Policy Agent features must be explicitly turned off
before TCP Chimney can function.
To disable this feature, use the following procedure:
1. Start Computer Management - from the Start menu, right click My Computer
and select Manage.
2. Under Services and Applications, click on Services. On the right side, scroll
down and double click on Windows Firewall/Internet Connection Sharing

Alacritech Accelerator Users Guide
3-12
4. Select the Advanced tab to access the properties that are available for the selected Accelerator.
The following settings are available under the Advanced tab:
IP Checksum Offload (IPv4) – The IP Checksum Offload option will allow the Accele-
rator to offload the IP checksum for IP data transmitted and received when the Accelerator has the TCP Offload disabled or the Microsoft stack has chosen not to offload a
TCP connection to the Alacritech Accelerator. An example of this would be the used of
IPSec which cannot be offloaded to the Alacritech Accelerator. Because Alacritech‘s
SLIC Technology offloads the checksum automatically, this option is unused except
when TCP traffic is not offloaded.
The default value for IP Checksum Offload is Enabled.
Jumbo Packets – Allows the Accelerator to be configured to use jumbo frames. The
default setting is for standard Ethernet frames. Alacritech Accelerators support 9014
byte jumbo frames as well.
Link Speed & Duplex – This option allows for the direct setting of the data transmis-
sion rate. The default for this setting is Auto Detect. The available options for this setting are shown in the following table.

Receive Side Scaling – Receive Side Scaling allows network interrupts from the Ala-
critech Accelerator to be spread over all CPU cores in a multi-core server.
TCP Checksum Offload (IPv4) – The TCP Checksum Offload option will allow the
Accelerator to offload the TCP checksum for TCP data transmitted and received when
the Accelerator has the TCP Offload disabled or the Microsoft stack has chosen not to
offload a TCP connection to the Alacritech Accelerator. Because Alacritech‘s SLIC
Technology offloads the checksum automatically, this option is unused except when
TCP traffic is not offloaded.
The default value for TCP Checksum Offload is Enabled.
Alacritech Accelerator Users Guide
3-14
TCP Large Send Offload (LSO v1 IPv4) – TCP Large Send Offload is a ―stateless‖
offload technology supported by the Alacritech Accelerator. It provides some of the
benefit of full TCP offload but still results in multiple CPU interrupts for large payloads.
Because Alacritech‘s SLIC Technology offloads all TCP Processing, this option is un-
used except when TCP traffic is not offloaded.
The default value for TCP Large Send Offload is Enabled.
3.7 Configuring Teaming and Failover
Alacritech SNP Drivers support network teaming and failover. Two different types of
failover are supported:
Cisco Fast EtherChannel/802.3AD
Hot-Stand-by Fail-over
Given the flexible nature of Alacritech‘s teaming implementation, it is possible that it
may work with other proprietary solutions as well. For more information on our current
teaming support, visit our Customer Support website at
http://www.alacritech.com/Support/Overview.aspx
It is important to note that EtherChannel and 802.3AD require that the team be configured on the host and on the switch that the host connects to.
Note: Alacritech’s Teaming implementation does not support the optional Port
Aggregation Protocol (PAgP) feature that is part of the EtherChannel Protocol. Nor is the LACP portion of the 802.3ad protocol Supported.
PAgP/LACP facilitates the automatic creation of link aggregation groups
by exchanging packets between channel-capable ports. All EtherChannel
or Link Aggregation groups that connect to Alacritech Accelerator teams
must be manually configured. The specific details of manual vs. auto configuration are vendor specific. Consult your switch documentation.
3.7.1 Recommended Order of Implementation
Alacritech strongly recommends that teams be created using the following sequence.
Using an alternative sequence of steps may result in unpredictable behavior.
1. Establish TCP/IP communication over a single Ethernet link. If this is a new installation of an Alacritech Accelerator it is important that network connectivity
be established before configuring a team. All other ports that will later be used
on the team should be disabled and not have cables connected to them.
2. If using EtherChannel/802.3AD, set up the switch according to the vendor‘s in-
structions. Once the team is set up on the switch you will have full network
connectivity as long as there is only one physical connection to the host.
3. Set up the team on the host using the steps below.
4. Connect the remaining Ethernet cables to the appropriate switch and host
ports. Verify the link on all connections. You should now have a fully functional
team.
Alacritech Accelerator Users Guide

3.7.2 Configuring a team
1. From the Start menu, open the Network Connections folder located under the
Settings menu.
2. Click the LAN connection of the interface you wish to configure in a team.
3. Click the Configure button. The Accelerator Properties dialog box will appear.
Select Teaming.
4. To configure a team select the interfaces you wish to team and click the New
Team button.
Alacritech Accelerator Users Guide
3-16
5. Once the team is created you must specify which type of teaming or failover
that the team will utilize.
6. The default is Cisco Fast EtherChannel/802.3AD. Select OK.
7. If Cisco Fast EtherChannel/802.3AD is selected then you must have switch that
supports one of these protocols. If you do, click the Yes button. Otherwise click
the No button and choose Hot Stand-by Fail-over.

3.7.3 EtherChannel Guidelines and Restrictions
If you disable a port in a team, it is treated as a link failure and its traffic is
transferred to one or more of the remaining ports in the team.
Configure all ports in a team to operate at the same speed and duplex mode
(full or half duplex).
Ensure that all ports in a team have the same configuration on both ends of the
link.
3.7.4 Removing Teaming
1. From the start menu, open the network connections menu under the settings
tab. Right click on a member of the team you wish to reconfigure and select
properties.
2. Highlight Client for Microsoft Networks and click Configure.

3.8 Configuring VLAN Tagging
Alacritech SNP Drivers support VLAN Tagging allowing the user to create Virtual Local
Area Networks when used with switches conforming to the IEEE 802.1Q VLAN Tagging Specification.
3.8.1 Recommended Order of Implementation
Alacritech strongly recommends that VLANs be created using the following sequence.
Using an alternative sequence of steps may result in unpredictable behavior.
1. Configure the switch on which the VLAN is to be created. Different switch vendors have different configuration interfaces which are outside the scope of this
document, but the basic procedure is as follows. (For the purposes of this example two VLANs are created—one for the Engineering department (100) and
one for the Finance department (200) )
a. Create the Engineering VLAN within the switch and assign it a tag of 100.
b. Add the Engineering tag (100) to the switch port connecting to the Alacri-
tech Accelerator (usually on a server). Add the Engineering tag (100) to
each switch port connected to an Engineering computer.
c. Repeat Step a. for the Finance VLAN (tag of 200).
d. Add the Finance tag to the same switch port connecting to the Alacritech
Accelerator. Add the Finance tag (200) to each switch port connecting to a
Finance computer.

3.8.2 Configuring a VLAN
1. From the Start menu, open the Network Connections folder located under the
Settings menu. For this example a SEN2104ET (4-port adapter) is used.
2. Click the LAN connection of the interface to be converted to a VLAN (Port A in
this example).

5. Click OK and then add the 2nd VLAN again using the Add VLAN button. After
the 2nd VLAN is created the VLAN list will show both VLANs.
6. Now click OK to create the two requested VLANs. These appear as unique devices in the Network Connection Property Frame.

7. Configure each of these new devices as a normal network connection. Each
requires its own unique IP address on a separate subnet. Notice that Port A of
the adapter shows ―Network cable unplugged.‖ This connection is no longer
available and is now replaced by the two VLAN network adapters (Local Area
Connection 7 and 8).
8. The two VLANs are now configured and should be isolated at the network level. A quick isolation test is to ping an Engineering system from a Finance system. The ping should fail. A ping of a Finance system from another Finance
system should succeed.

Problem
Solution
There is no connectivity at all with other
computers on the
network.
Pinging does not
work.
Make sure that the cables are attached securely at both
RJ-45 connections (adapter and switch) and that the
network cable is otherwise functional.
Make sure that the network cables are plugged into the
correct port of the adapter. The driver will list the slot and
port for the interface.
Check the LED indicators on the adapter. Each port has
LEDs for link/link speed and activity. These lights help
indicate if there is a problem with the adapter, switch or
cable. Refer to the "LED Function Indicators" chart below.
