Mixed Adapter Teaming
AFT supports up to eight server adapters per team, in any mix.
Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient way to increase your
server’s transmit throughput. With ALB you group server adapters in teams to
provide an increased transmit rate (up to 8 Gbps) using a maximum of eight
adapters. The ALB software continuously analyses transmit loading on each adapter
and balances the rate across the adapters as needed. Adapter teams configured for
ALB also provide the benefits of AFT. Receive rates remain at 100 Mbps or 1 Gbps
depending on the primary adapter’s capability.
To use ALB, you must have 2-8 server adapters installed in your server or
workstation and linked to the same network switch.
Cisco Fast EtherChannel
Fast EtherChannel (FEC) is a performance technology developed by Cisco to
increase your server’s throughput. Unlike ALB, FEC can be configured to increase
both transmission and reception channels between your server and switch. FEC
works only with FEC-enabled switches, such as the Catalyst 5000 series. With FEC,
as you add adapters to your server, you can group them in teams to provide up to 18
Gbps at full duplex, with a maximum of 8 server adapters. The FEC software
continuously analyses loading on each adapter and balances network traffic across
the adapters as needed. Adapter teams configured for FEC also provide the benefits
of AFT.
To use FEC, you must have 2, 4, or 8 server adapters installed in your server and
linked to the same FEC-enabled Cisco switch.
Keyboard and Mouse
The keyboard/mouse controller is PS/2-compatible. If specified through the System
Setup Utility (SSU), the server may be locked automatically if there is no keyboard or
mouse activity for a predefined length of time. Once the inactivity (lockout) timer has
expired, the keyboard and mouse do not respond until the previously stored
password is entered. A Y-cable can be used if both a PS/2 mouse and keyboard are
required at the same time.
RJ-45 Serial Port
The rear RJ-45 serial port is a fully functional COM port that supports any standard
serial device and provides support for serial concentrators, which typically support
RJ45 serial connectors. For server applications that use a serial concentrator to
access the server management features of the baseboard, a standard 8-pin CAT-5
cable from the serial concentrator is plugged directly into the rear RJ45 serial port.
