This page is to answer the question "what do they mean by IP30, IP35, etc?" If you are looking for the page for decoding SGI model numbers.. go to: SGI model numbers

"IP" stand for "Inhouse Processor" module.[2] The "hardware IP" number is akin to the revision of the physical module itself. The "software IP" number is related to compatibility of architecture across a range of physical modules. Thus, a 4D/240 would boot sash.IP7 (HW IP) only but share unix.IP5 (SW IP) with many of its cousin systems.

"The antics of the IP numbering system are quite interesting, though - I've got a Personal Iris 4D/20 which is labelled up as a IP6.5 - and appears to be an IP12 complete with R3000@20MHz - but underclocked to 12MHz to render it functionally equivalent to a IP6. Dave Olson states in the past that at the end-of-life of the 4D/20 SGI ended up underclocking (possibly slightly defective) 4D/25s and selling them as 4D/20s - although makes no reference to changing the IP number on those boards." [2]

Even numbered machines are always "lower-end of the era", ie workstations as apposed to servers, which explains some of the gaps at least.

(*) "IP1 never officially existed. If anything, it was a relabelling of the PM2 board as used in the IRIS 1400, 1500, 2000, 2200, 2300, 2400 and 2500. The first actually used IP series board was the IP2 as used in the 2300T, 2400T, 2500T and 3000 series machines. The main distinction between the PM and IP boards were that the PM were based on reference boards developed at Stanford University whereas the IP boards were (and still are, i hope ;) developed in house by SGI themselves (although often based on reference boards from MIPS - explicitly the case for the original IP4 boards used in the 4D/50; the first of the MIPS machines). Or perhaps the IP1 was a prototype of the "Turbo" 68020-based motherboard that eventually became the IP2." [2]
