Debian has already dropped 32-bit PowerPC as a release architecture; 64-bit is still supported. And I've heard mutterings that i386 is getting too long in the tooth and that amd64 is very much the core architecture today. We're already seeing browsers needing ginormous address space and not playing nicely on smaller computers with less than four gig in which to romp. I'm expecting that 64-bit processors are going to become increasingly less optional in the desktop and server space, and that there may be a fork at some point with the full distros focussing on 64-bit and embedded distros being the thing to use on 32-bit hardware. 64-bit ARM has been awfully slow off the mark but is likely to be a big thing once it gets properly going. The only reasonable thing I've seen actually for sale and have personally touched and run is the Solidrun Macchiatobin. Decent little board, supports a proper DIMM-load of RAM, the 10gig SFP slots are overkill for most of us but it has a normal GigE port too. I haven't tried video but I've heard reports of people having luck with a card of the appropriate PCI flavour. (Technically you can boot arm64 on some Raspberry Pis, but they don't have enough RAM to make that worth trying.) -- Anthony de Boer --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk

I think the most powerful I managed to get my hands on was an 8 core 64bit A53 reference board from Freescale (NXP? Qualcomm?) but that was a pain to try to work with because the network ports were totally weird and non standard and kernel support was not integrated yet. > But yes, the long promised ARM in the datacentre thing seems to remain > just that, a promise with no major channel resellers or anyone offering > much in terms of product. > > HP tried high density ARM servers with its Moonshot blades, but it seems > like that effort died off in 2014 as soon as it started, and the whole > HP/HPE thing the next year probably didn't help. Also a box full of independant small 32 bit arm servers was not what people wanted. They wanted large single image multicore 64 bit arm servers. -- Len Sorensen --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
