Description
Alacritech Accelerators are single-port or multi-port network
interface cards (NICs) that employ Alacritech’s SLIC (SessionLayer Interface Card) Technology, which uses an innovative
application-specific integrated circuit (ASIC) for protocol
processing. Accelerators operate with Windows 2000, Windows
XP and Windows Server 2003 operating systems.
SLIC Technology increases server performance and efficiency in
two specific ways:
1-2
Alacritech Accelerator Users Guide
•
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 Operations and Management
3.1
Overview of Performance Monitoring
Performance data for an Accelerator can be seen with Performance
Monitor, which is located in the Administrative Tools folder on
your Windows system. Select the SLIC object in the Performance
Monitor program to review SLIC specific counters. Among the
counters maintained under the SLIC object is the FastPath Data
Rate. This counter measures the percentage of TCP/IP traffic that is
being processed by the Accelerator as opposed to the traffic that is
processed by the host protocol stack. A FastPath Data Rate of
95% or higher indicates the accelerator is working properly.
3.1.1 Using the Performance Monitor Application
To check the performance of your system, run Performance
Monitor, specifying the variables you wish to monitor. Follow this
procedure to check the performance of the Accelerator.
Alacritech Accelerator Users Guide
3-1
For Windows 2000, run the Performance Monitor application from
the Start Menu, located under Settings in the Control Panel folder in
the Administrative Tools object. For Windows XP and Windows
Server 2003, click the Start menu button, and launch the Run…
menu option. In the dialog box that appears, run the command
perfmon. Follow the steps below:
1. Select the + button to add objects to the chart:
2. In the Performance Object field, select Processor and in
the Counter field, select % Processor Time and click the
Add button. Next, in the Object field, select Net and in the
Counter field, select Bytes Total/sec along with any
gigabit adapter in the list of available network interface
instances, and click the Add button. These objects display
both how much CPU time is used on the system and how
much data is transferred by the Server process, which is
responsible for file sharing.
Before the Alacritech Accelerator is installed, when clients
are generating a lot of traffic to and from the server's file
systems, your display may look similar to this:
3-2
Alacritech Accelerator Users Guide
In this example, the CPU usage is over 50% (black,
highlighted line). The throughput is not optimal (75MB/s)
and occasionally a drop in performance occurs. This shows
how a conventional NIC uses lots of CPU to accomplish
non-optimal throughput.
Alacritech Accelerator Users Guide
3-3
3. With an Alacritech Accelerator installed, add Alacritech
specific objects to the chart. In the Object field, select
SLIC and in the Counter field, select FastBytesTotal/sec
and click the Add button. Next, in the Object field, select
SLIC and in the Counter field, select SlowBytesTotal/sec
and click the Add button. FastBytes represents data moving
through the Accelerators on-card TCP/IP protocol stack
(FastPath) and SlowBytes represent data moving through
the host protocol stack, as it does with a conventional
network interface card.
3-4
Alacritech Accelerator Users Guide
4. When running either read or write network tests through an
Alacritech Accelerator, your display should look similar to
this:
Note the same server's CPU is now at around 5% (green
line). Also, the data being transferred as indicated by
FastBytesTotal/sec is entirely FastPath (black line,
highlighted), running at wire speed (119MB/s).
SlowBytesTotal /sec is non-existent. The percentage of
FastPath data on a healthy network should be close to
100%. This indicates that the Alacritech Accelerator is
offloading 100% of the traffic from the server's CPU.
If your FastPath results do not indicate similar kinds of
performance benefits, take the additional steps indicated in the
Problem/Solution table in the Chapter 6.
3.1.2 Explanation of SLIC Performance Monitor Objects
The basic indication of SLIC and network functionality is the
amount of data moved through the SLIC protocol stack instead of
Alacritech Accelerator Users Guide
3-5
through the Windows (host) TCP/IP protocol stack. If most of the
data is moving through the SLIC protocol stack, then performance
of the server will be optimal. Some reasons why data may not be
going through the SLIC protocol stack are:
•
Faulty network wiring or bad connections leading to
dropped frames and runt packets;
•
Inability of older network hardware to autonegotiate
properly;
•
Extremely high network traffic that causes dropped frames
on an intermediate network device such as a switch or hub.
The purpose of the SLIC Performance Monitor objects is to measure
the amount of data transmitted using the SLIC protocol stack, or
FastPath. Any data that is moved using the host protocol stack
instead of the SLIC protocol stack is referred to as SlowPath data. A
healthy TCP/IP connection will be put into FastPath state as soon as
the connection is established, and will stay in FastPath state until the
connection is closed.
As soon as an Alacritech Accelerator finds a problem with a
connection such as a dropped frame, the connection is flushed back
to the host, and is put under the control of the host protocol stack,
SlowPath, until the problem can be resolved. While the connection
is in this SlowPath state, all TCP/IP processing is handled by the
host and the Alacritech accelerator serves only to move Ethernet
frames to and from the network, much like a conventional network
interface card. When the host resolves the network problem, for
example by a retransmission, the connection is moved into FastPath
state and the Alacritech Accelerator once again takes over TCP/IP
processing. The FastPath data rate is the best indication of how
much data is being transmitted using the SLIC protocol stack and
should be at least 95%.
The table below indicates the SLIC objects and counters relevant to
the Accelerator for use with the Performance Monitor.

3. Click the Run button. The adapter will then run through
self-test of the IPP and the selected Accelerator. A properly
functioning board will display Passed for all results. Click
the Close button to exit the slicuser application.
3.3
Updating Flash Code
A new mechanism for flashing code on flash-capable Accelerators
is now provided through the slicuser application. The PXE/UNDI
drivers for Alacritech Accelerators allow PXE and iSCSI software
boot solutions to work. Note that these drivers do not include a
BIOS-level iSCSI boot driver, and that a third-party iSCSI boot
software package is needed for complete iSCSI boot support.
Alacritech Accelerator Users Guide
3-9
The latest PXE drivers are available from Alacritech’s web site in
the Support section.
To burn the latest flash code on an Accelerator, follow these steps:
1. Click the Flash Update tab in the slicuser application.
2. Specify the flash image directory by either entering the
appropriate path to the flash files in the Flash Image
Directory text box or by browsing to the appropriate path
by clicking the Browse button.
3. Once the path is specified, click the Update Flash button to
complete the flash process. NOTE: The Accelerator may
not be available or operational during the flash update
process and will disrupt all ports of the Accelerator being
flashed in the server.
4. After flashing the latest PXE drivers, click the Close button
to exit the slicuser application.

Disabling SLIC TCP/IP Offload on Select Interfaces
In certain environments, such as networks with routing loops, it may
be necessary to disable the SLIC TCP/IP Offload feature on the
Accelerators in your system. To determine if this is required on any
of your Accelerators, please read the Troubleshooting and Support
chapter. To disable this feature, use the following procedure:
Note: Disabling SLIC TCP/IP Offload will disable the
performance benefits of the Accelerator on that
interface. This should be done only as required.
1. From the Start menu, open the Network & Dial-up
Connections folder located under the Settings menu.
2. Double-click the LAN connection of the interface you wish to
disable TCP offload.

The default value for Link Speed & Duplex is Auto Detect.
TCP Checksum Offload – The TCP Checksum Offload option will
allow the Accelerator to offload the TCP checksum for TCP data
Alacritech Accelerator Users Guide
3-15
transmitted and received when the Accelerator has the Alacritech
TCP Fast-path driver option disabled. Because Alacritech’s SLIC
Technology offloads the checksum automatically, this option is
unused except when FastPath is turned off.
The default value for TCP Checksum Offload is Disabled.
TCP Large Send Offload – In a standard network configuration,
the TCP stack will break the entire TCP segment down into Ethernet
frames. Each frame is then transmitted individually. TCP Large
Send Offload allows an entire data buffer to be sent by the
Accelerator as a single segment, using only one interrupt.
The TCP Large Send Offload option will allow the Accelerator to
perform segmentation offload for TCP data transmitted and received
when the Accelerator has the Alacritech TCP Fast-path driver
option disabled. Because Alacritech’s SLIC Technology offloads
all TCP data to the hardware automatically, this option is unused
except when FastPath is turned off.
The default value for TCP Large Send Offload is Disabled.
VLAN Identifier – This setting allows the network administrator to
set the VLAN identifier. The VLAN identifier indicates a specific
VLAN the Accelerator will connect to. This setting may be set to a
value between 1 and 4094.
The default value for VLAN Identifier is 1.
VLAN Tagging This feature allows the use of 802.3ac VLAN Tagging. This
standard provides for the insertion of an identifier, known as a tag.
This tag identifies to which VLAN the frame belongs.
The default for VLAN Tagging is Disabled.

4 Configuring Teaming and Failover
4.1
Overview of Teaming and Failover
Teaming, trunking, link aggregation, port aggregation, load
balancing, call it what you will. Though these terms are not
synonymous, from Alacritech’s perspective they mean the same
thing – gathering several Ethernet link level connections together to
form a single logical IP network connection.
Note: Alacritech’s FastPath implementation works
specifically with Alacritech’s teaming and failover
solution. FastPath is not compatible with
Microsoft’s Network Load Balancing feature.
Alacritech offers several teaming and failover methods:
•
•
•
Cisco EtherChannel compatible
IEEE 802.3AD Link Aggregation Group
Hot standby failover
Given the flexible nature of Alacritech’s teaming implementation, it
is possible that it may work with other proprietary trunking
solutions as well. For more information on our current teaming
support, visit our Customer Support web site at:
http://www.alacritech.com/html/techsupport.html
Alacritech Accelerator Users Guide
4-1
It is important to note that EtherChannel and 802.3AD require that
the team be configured both on the host, and on the switch that the
host connects to.
In a configuration that has one or more Alacritech Accelerators
connected to a compatible switch, EtherChannel allows multiple
full-duplex Gigabit Ethernet connections to be grouped together into
a single logical path between the host server and the switch, creating
a high-speed, fault tolerant link that shares a single IP address. For
example, four (4) Accelerators can be configured to form a Gigabit
EtherChannel with four (4) compatibly configured ports on the
switch. The switch distributes frames across the ports in a Gigabit
EtherChannel according to an algorithm determined by the switch
vendor. Some switches may have several user selectable
algorithms, but typically what is used is a hash based on the source
and destination Media Access Control (MAC) addresses. If a port
within a Gigabit EtherChannel fails, traffic previously carried over
the failed port switches to the remaining ports within the Gigabit
EtherChannel. In all cases, traffic between any client/server pair is
restricted to one port at a time, limiting bandwidth per client to 1
Gbps half duplex or 2 Gbps full duplex. Multiple clients can
collectively take advantage of the full 4 Gbps of a four-port trunk
group.
Fault tolerance and load balancing is provided for data both to and
from the server (instead of just from the server, as with some other
port aggregation schemes). This enables bandwidth to be scaled up
to 4 Gbps when four (4) Accelerators are connected to a Gigabit
EtherChannel-enabled switch.
Note: Alacritech’s Teaming implementation does not
support the optional Port Aggregation Protocol
(PAgP) feature of some EtherChannel and 802.3AD
cable switches, nor the 802.3AD LACP protocol.
PAgP/LACP facilitates the automatic creation of
4-2
Alacritech Accelerator Users Guide
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.
Hot-standby failover is a failover/redundancy option (no loadbalancing). One Accelerator port is placed online while other ports
in the team are offline. If the link for the online port fails, it is taken
offline and one of the other ports is set online in its place.
4.2
Recommended Order of Implementation
Because setting up a team correctly can be tricky, and because the
results of an invalid configuration can cause bizarre and
unpredictable behavior, we recommend the teamed connection be
set up in the following sequence:
1. Establish TCP/IP communication over a single Ethernet
link. If this is a new installation of an Alacritech
Accelerator, it is important that you first establish network
connectivity before setting up a team. All other ports that
will later be used in the team should be disabled, and not
have Ethernet cables connected.
2. If using EtherChannel or 802.3AD, set up the team on the
switch according to the vendor’s instructions. Once the
team is set up on the switch, you will have full network
connectivity, as long as you have only one physical
connection to the host.
3. Set up the team on the hosts based on the steps below.
Alacritech Accelerator Users Guide
4-3
4. Connect the remaining Ethernet cables to the appropriate
switch and host ports. Verify that you have link on all
connections. You should now have a fully functional faulttolerant network team.
4.3

button to reboot and activate Alacritech SLIC TCP/IP Offload.
Note: A team can have up to four member interfaces,
and these interfaces may be on up to four cards.
Note: Remember to configure the switch ports as a Port
Aggregation Team. The use of EtherChannel or
802.3AD Link Aggregation requires cooperation
between the switch and the cards.
Alacritech Accelerator Users Guide

4.3.2
EtherChannel Configuration 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.
•
Alacritech’s EtherChannel implementation does not support
PAgP. Switch ports should be configured in the on mode.
4.3.3 Removing Teaming
1. From the Start menu, open the Network & Dial-up
Connections folder located under the Settings menu.
2. Double-click a physical LAN connection for the team you
wish to reconfigure.

5 Alacritech Accelerator Installation in
Windows Powered NAS Appliance
5.1
Installation Overview
This chapter address issues specific to the installation of an
Alacritech Accelerator in a Windows Powered NAS appliance. The
procedures outlined in this chapter cover the following types of
situations:
•
Installation of the Accelerator during a new install
•
Replacement of the existing network adapter with a new
Alacritech Accelerator in a previously configured system
•
Addition of an Alacritech Accelerator to a previously
configured system
Note: Alacritech's SLIC Technology requires the
installation of additional components not typically
required by a network adapter in order to support
the TCP offload capabilities of the server
accelerator. All software installations must be
done with the Alacritech Setup utility typically
found on the Alacritech Driver Installation CD.
Alacritech Accelerator Users Guide
5-1
5.2
Adapter and Driver Installation
This section covers the procedures for installing Alacritech
Accelerators. Follow the appropriate procedure for your type of
installation.
Note: Running the Alacritech Setup program is the only
way to correctly install Accelerator drivers for
Windows. Following initial installation, the
automated Add/Remove Hardware Wizard will
discover additional Accelerators.
Note: The drivers cannot be installed during the initial
installation of Windows. If you leave the
Accelerator in your system through the entire
Windows installation process, the automated
Add/Remove Hardware Wizard will not discover
the Accelerator in you system on subsequent
reboots, since Alacritech drivers do not ship with
Windows.
5.2.1
Installation of an Alacritech Accelerator in a Windows
Powered NAS Appliance
These procedures outline the steps required to install an Alacritech
Accelerator in a Windows Powered NAS appliance. It will be
necessary to attach a keyboard, monitor, and mouse to enable the
installation of the Alacritech drivers on the NAS appliance.
1. If this system has been previously configured, make
backups prior to commencing these activities.
2. If this is a new system installation, perform initial
configuration activities, following procedures outlined in
the Windows Powered NAS documentation.
3. Turn off and unplug the computer. Failure to do so could
endanger you, and may damage the computer.

Performance Monitoring
The performance of an Alacritech Accelerator can be monitored
using the Windows Performance Monitor tool, perfmon. Because
the Windows Powered NAS appliance does not typically have its
own display, it is necessary to access perfmon on the NAS
appliance through Terminal Services. It is not possible to remotely
monitor performance on a Windows Powered NAS appliance.
Refer to Chapter 3 of this guide for complete details on the
Alacritech performance monitoring objects.

5.4
Adapter Teaming
Alacritech Accelerator ports can be teamed together to provide fault
tolerance and ease of administration when multiple ports or adapters
are installed in Windows Powered NAS appliances. The Alacritech
Accelerator Team Configurator utility is accessed by opening up a
terminal services session on the NAS appliance and then by running
the Alacritech teaming from the network properties screen. The
adapter teaming option must be installed to use this option. Refer to

6.6
Connectivity Problems
This section covers problems with network connectivity.
Problem
Solution
There is no
connectivity at all with
other computers on the
network.
Make sure that the cables are attached
securely at both RJ-45 connections
(adapter and switch) and that the
network cable is otherwise functional.
Pinging does not work.
Make sure that the network cables are
plugged into the correct port of the
adapter. The lowest numbered SLIC
interface in the system will
correspond to the port marked "A" on
the card. (SLIC1 corresponds to port
6-4
Alacritech Accelerator Users Guide
Problem
Solution
A, SLIC2 to port B, etc.)
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.
Problem
Solution
TCP connections can
be established to other
systems on the same
subnet, but
connections cannot be
established to systems
on the other side of a
router.
If you have an Accelerator and another
brand adapter installed on your system,
AND your network is configured such
that the route from your system to the
remote system is different than the route
from the remote system back to your
system (a routing loop), then it may not
be possible to establish a TCP connection.
There are three ways to solve this
problem:
1. Replace the existing adapter in
your system with an Alacritech
Accelerator, or
2. Reconfigure your network to
eliminate the routing loop, or
3. Disable TCP/IP Offload on the
interface(s) associated with the
routing loop by following the
instructions specified in
"Disabling SLIC TCP/IP Offload
on Select Interfaces" in Chapter 3.

Performance Problems
This section covers issues surrounding the performance increase
that should occur with the Accelerator installation.
If you suspect performance degradation, follow the steps in Chapter
3 to check your server’s performance.
A low FastPath data rate will result in lower performance and is
usually the result of a faulty network connection. If the FastPath
data rate is high, then the Accelerator is working properly and the
performance problems of your system are probably not related to
networking (a bottleneck in the disk subsystem for example).

Solution
Performance
improvements of the
Accelerator are not
apparent.
Look at the Properties for an
Alacritech accelerator listed in the
Network and Dial-Up Connections
window and verify that the Alacritech
TCP Fast-path driver is both listed
and checked.
Make sure that your clients are
connected to the server using TCP/IP
instead of other protocols such as
NetBEUI or IPX/SPX. Windows 9x
systems will use NetBEUI or
IPX/SPX by default if possible. This
can be prevented by ensuring that
TCP/IP is installed on the clients and
then either removing NetBEUI and
IPX/SPX on the server or disabling
them in the bindings tab of the
NCPA.
Use the Performance Monitor
application as described in Chapter 3
to verify the FastPath performance of
your server.
