Server Load Balancing

• Client NAT behavior—For an IIS server running multiple logical servers, some applications
(such as HTTP) need the client IP addesses to be masked using Proxy-IP/Client-NAT and perform
persistency using other methods (cookies) or allow multiplexing to be used to improve the
server's efficiency, and other applications (such as FTP) require that the client IP addresses not
be masked to allow client-IP persistency. Using a logical server proxy mode, you can define
multiple real servers with desired rports (or in different groups), all with the same IP address,
and set each real server proxy mode to its desired value.
Notes
• DAM must be turned on or a proxy must be used to support multiple real servers with the same
IP address.
• Multiple real servers with the same IP address cannot share the same addports. Multiple real
servers with the same IP address with no addport configured must be associated to different
server groups.
Supported Services and Applications
Each virtual server can be configured to support up to eight services, limited to a total of 1023
services per Alteon. Using the /cfg/slb/virt <virtual server number> /service option,
the following TCP/UDP applications can be specified:
Note: The service number specified on Alteon must match the service specified on the server.
Notes
• Load balancing some applications (such as FTP and RTSP) require special configuration. For
more information, see Load Balancing Special Services, page 279
.
• For all applications without a well-known port, you can select Basic-SLB as the application.
