Not a hard configuration requirement but you want the amount of work (number of AMPs per node) balanced across same generation node hardware
models. As in any parallel architecture a process is only as fast as its slowest unit. The number of bytes of storage per AMP will be
equivalent; dictated by database configuration. So if you have different number of LUNs/PDISKs whatever (different number of bytes) per AMP the
smallest amount becomes the MAXPERM per AMP.
With co-existent configurations (multiple node hardware models) there will most likely be more VAMPs per node on the newer generation node
hardware. Also, if the configuration would be strictly OLTP (or even OLCP I would think) that could change the total number of VPROCs per node as
the PEs become a lot more resource intensive.
