Thumper local port to switch port mappings and trunking tests

Local port to switch port mappings

These mappings are needed for correctly configuring the switch

For incoming connections, the 4 bonded interfaces of each X4500 must be known to the Switch, so that these connections are balanced over the interfaces.

Testing of the X4500's interface bonding

The tests used my IperfLoadTest test suite.

Test setup:

  • 3 X4500 servers (Thumpers) with 4*1Gb/s aggregated (bonded) interfaces (File Servers). t3fs01 and t3fs03 were running Solaris 10 while t3fs02 was running OpenSolaris
  • 7 X4150 servers with 1*1Gb/s interface (Worker Nodes)

Tests for worker nodes sending data to fileservers

This is testing the switch and the hash function it uses to balance connections between the target interfaces on every thumper. The CISCO switches we use are regrettably only able to do IP or MAC based hashing.

Measurements for worker nodes sending

Every measurement was run for 60s with client processes on the worker nodes sending TCP streams to receiving processes on the fileservers.
