Considering we are buying a new iSeries with the Power 9 this year, I expect to have an AS/400 descendent in our server room for another 10 years. The last one lasted 13 years.
- nickpsecurity 8y agoDon't be assured of that: the failure modes of silicon increase every time you shrink it due to physics just being a huge problem. That's one of reasons new stuff doesn't last as long. The new systems will run on nodes with more problems developers have to fight. I suspect they systems won't last as long. I appreciate the data point on that one. Sounds like it aged well. Which CPU('s) did it have?
- protomyth 8y agoWell, since IBM generally shows up with replacement parts before I even known there is a problem, I'm not terribly worried about its length of service. The current one is an IBM 9406-800 which I do believe is the SStar which is the RS64 before the POWER 4.
- nickpsecurity 8y agoNow that's good service. Far as CPU, I found there are several of them. They are on a range of 180nm-500nm nodes. Most of the older, long-lasting stuff was on those nodes. So, that fits. It was also the ones just before merger of those AS/400 chips and POWER families into POWER4 to become new standard. Interesting stuff. https://en.m.wikipedia.org/wiki/IBM_RS64 https://en.m.wikipedia.org/wiki/IBM_RS64
- protomyth 8y agoThat's pretty much the standard of service with these things. We are going with an S914 running IBM i 7.3 for the next machine. Interestingly, the old machine has a tape drive that is not supported on the new Power 9 boxes (its a non-LTO QIC drive). I guess the good thing is now I can keep a single stock of LTO-7 tapes. I am a bit odd and have an LTO-7 drive connected to our FreeBSD server for a "last chance" backup.
