interesting. i run ~25 t1 105s. for ages. 3 have fan failures. that's it. and they run fine without replacing that fan even :) a handful of v100, v120, v210 each. no failures at all. i think i had one ss20 die ages ago. at a point where that kind of machine was ancient already. i still have a stack of them somewhere. prety sure if i'd power them up now the vast majority would be ok after un-dusting, reseating mem and the like. my u1s are alive (but off too). the ss5s probably in the same boat as the ss20s. even the really ancient ipxes are pbly still ok. can't be bothered to check tho. u5/u10 was crap, for sun standards, and if memory serves i had one out of 3 fail. u30 alive. e220r, e420r, no failures. so the only ones that ever failed (fans and disks i expect to fail sooner or later, so my definition of "machine failed" excludes these parts) were not from the server line, but workstations. that matches the majority of your list. that track record is way ahead of anything else i run and ever ran. i have to add here that i have extremely low failure rates. apparently a pretty good hand at picking hardware plus a very friendly environment - data center, very stable and low temp, high forced airflow, very little dust. oh, and that covers only sparc/sparc64 gear. sun's x86 gear was never even remotely up to that standards, haven't seen a single that remotely convinced me, the few i worked with... x2100 of both generations were the trigger to not consider sun for x86 gear, they're misdesigned shit. recently worked with some x4something at a customer, holy crap, their management stuff these days is so incredibly bad and not helping at all, but drastically in the way. -- Henning Brauer, [email protected], [email protected] BS Web Services, http://bsws.de Full-Service ISP - Secure Hosting, Mail and DNS Services Dedicated Servers, Rootservers, Application Hosting
