The Netezza strategy for data shipping

I talked with Netezza today, and finally understand better why they don’t have node-to-node data shipping problems with only 1-gigabit (gigE) interconnects:

  1. Netezza boxes have lots of relatively small nodes, so all else being equal, each individual node has less communicating to do than, say, a DATAllegro node does.
  2. It’s not just just 1-gigabit. There’s a hierarchical communications architecture, and at one level in the hierarchy switches are talking to each other through 32 parallel 1-gigabit channels at a time.
