«Ядерная физика» и IBM x3950

IBM x3950Как известно, ядерный физик — это человек, который удовлетворяет своё любопытство за государственный счёт. И в этом они в чём то схожи с системным администратором. По работе мне выдался шанс «пощупать» IBM X Series. IBM x3950 оказалась ничего так машинка, быстрая. -10sp1-x86_64 поставился на неё совершенно без проблем. До я загружал разные LiveCD: DSL, FreeBSD 7.0 — вроде всё работало. При установке всё железо распозналось системой. В общем-то процесс мало чем отличался от инсталляции на обычный PC — даже скучно как-то. А вот что в результате получилось:

Весьма примечательно, что 4 процессора «развернулись» в 16: 4 процессора, по 2 ядра, каждое с гипертритингом — вот в итоге и вышло столько.

Что ещё в итоге сказать? Жёсткие диски не очень большие (зеркало на 73 ГБ), так как основные объёмы носителей будут использованы на хранилищах.

Ну естественно, это только начало и «бесчеловечные опыты» продолжатся. Думаю, когда-нибудь руки дойдут и до P Series 🙂
