We (my company) do a lot of business with an IBM
dealer/reseller
in San Antonio, TX. Their systems guy sent me this spreadsheet the
other day listing *all* the RS6k/pSeries models, basic system info,
supported AIX versions, etc. It's not very detailed, but it's the
first really complete and coherent listing of models I've ever seen
(yes, including the telco variants and switches). He told me this
morning I can share it.
Sorry about the Excel format. I didn't make it and I haven't had
time to export it to something more universal.
