Overview
The CSM provides high-performance connections between network devices and server farms (groups of
real servers) based on Layer 4 through 7 packet information. Clients connect to the CSM by supplying
the virtual IP address (VIP) of the virtual server. The CSM is configured to handle VIP address
connections. When a client initiates a connection to the virtual server, the CSM chooses a real server (a
physical device that is assigned to a server farm) for the connection based on configured load-balancing
algorithms and policies.
Representing server farms as virtual servers facilitates scalability and availability. The addition of new
servers and the removal or failure of existing servers can occur at any time without affecting the virtual
server's availability.
Sticky connections limit traffic to individual servers. These connections are configured so that multiple
connections from the same client are stuck to the same real server using source IP addresses, source IP
subnets, cookies, secure socket layer (SSL), or redirected using the Hypertext Transfer Protocol (HTTP)
requests. Policies manage traffic by defining where to send client requests for information Configuring
server load balancing requires that you know the following:
