Note that for each virtual adapter created in the system, thats virtual Ethernet adapters, virtual SCSI adapters, and virtual fibre adapters, require a small amount of system RAM reserved.
On a system with ~60 LPARs, this overhead can amount to GB of RAM. Add 2 pairs of VIO servers and you can increase that overhead further again.
Utilising the Hardware based SEA can reduce the number of virtual ethernet adapters needed, but only for ethernet.

anyhow... nice read.
