Per Blade

A BIG-IP system creates one connection per blade to each peer. This provides a balanced performance approach between the per peer connection mode (only one connection) and a per tmm connection mode (a connection from each TMM). This mode only makes sense for a hardware chassis with multiple blades.

Each blade will make a single connection to each peer.
  1. Message arrives on Blade 0
  2. Blade 0 opens a connection to Server 1 and forwards the message
  3. Second message arrives
  4. Blade 1 opens a connection to server 1 and forwards the message

Note: A connection will not be opened to Server 2 until a message targeted at that server arrives.
