▁Design ▁▁ ▁In ▁ 2 0 1 2 ▁a ▁team ▁at ▁IBM ▁Research ▁Zürich ▁led ▁by ▁Ron ald ▁P . ▁Lu ij ten ▁started ▁purs uing ▁a ▁very ▁computational ▁dense , ▁and ▁energy ▁efficient ▁ 6 4 - bit ▁computer ▁design ▁based ▁on ▁comm od ity ▁components , ▁running ▁Linux . ▁A ▁system - on - ch ip ▁( So C ) ▁design ▁where ▁most ▁necessary ▁components ▁would ▁fit ▁on ▁a ▁single ▁chip ▁would ▁fit ▁these ▁goals ▁best , ▁and ▁a ▁definition ▁of ▁" m icro server " ▁emer ged ▁where ▁essentially ▁a ▁complete ▁mother board ▁( except ▁RAM , ▁boot ▁flash ▁and ▁power ▁conversion ▁circ uits ) ▁would ▁fit ▁on ▁chip . ▁AR M , ▁x 8 6 ▁and ▁Power ▁I SA - based ▁solutions ▁were ▁investig ated ▁and ▁a ▁solution ▁based ▁on ▁Fre esc ale ' s ▁Power ▁I SA - based ▁dual ▁core ▁P 5 0 2 0 ▁/ ▁quad ▁core ▁P 5 0 4 0 ▁processor ▁came ▁out ▁on ▁top ▁at ▁the ▁time ▁of ▁decision ▁in ▁ 2 0 1 2 . ▁ ▁The ▁concept ▁is ▁similar ▁to ▁IBM ' s ▁Blue ▁Gene ▁super comput ers ▁but ▁the ▁DO ME ▁micro server ▁is ▁designed ▁around ▁off ▁the ▁sh elf ▁components ▁and ▁will ▁run ▁standard ▁operating ▁systems ▁and ▁protocol s , ▁to ▁keep ▁development ▁and ▁component ▁costs ▁down . ▁ ▁The ▁complete ▁micro server ▁is ▁based ▁on ▁the ▁same ▁form ▁factor ▁as ▁standard ▁FB - DI MM ▁socket . ▁The ▁idea ▁is ▁to ▁fit ▁ 1 2 8 ▁of ▁these
