Ntau khib -mounted fais fab tuag thiab cov khoom siv hluav taws xob tau teev tseg tias yog 1U, 2 ua , 3U, thiab lwm yam. Kom beprecise, 1U sib npaug 1.75-nti (44.45mm) ntawm khib qhov siab. Yog li ntawd, a 2u rov mount qhov siab yuav yog 2 x 1.75 ", uas sib npaug 3.5-nti siab. A 3U qhov siab yuav yog 3 x 1.75 "= 5.25-nti.
Yog li ntawd, 2u yog dab tsi?
Ib U yog 1.75 nti (44.45mm); tus qauv khib, ntawm 19inches, yog 42U. Khib servers thiab lwm yam khoom siv uas tsim los rau berack-mounted yog tsim nyob rau hauv ntau yam ntawm 1.75 ntiv tes thiab qhia nyob rau hauv ntau yam ntawm khib units, feem ntau yog 1U, 2 ua ,3u4 ua. Racks yog tsim los tuav cov cuab yeej ntawm cov loj.
Tsis tas li ntawd, dab tsi yog 1 U hauv khib? A khib chav tsev yog ib chav tsev ntawm kev ntsuas siv los piav txog qhov siab ntawm lub server, hloov network lossis lwm yam khoom siv zoo sib xws hauv 19-nti khib los yog 23 nti khib . Oneerack chav tsev yog 44.45 hli (1.75 nyob rau hauv) siab. Ib lub khib unit feem ntau raug xaiv raws li " 1 UA "; ib, 2 khib units yog "2U" thiab lwm yam.
Raws li, 2u thiab 4u khib yog dab tsi?
A khib unit (abbreviated U los yog RU) yog ib chav tsev ntawm kev ntsuas raws li 1 3⁄4 ntiv tes (44.45mm). Piv txwv li, ib txwm puv-size khib tawb yog 42U siab, thaum cov khoom siv feem ntau yog 1U, 2 ua ,,3u, ua 4 ua U siab.
Qhov txawv ntawm 2u thiab 4u yog dab tsi?
Qhov tseem ceeb sib 2u vs 4 ua u servers yog ib qhov ceev los yog expandability. 2 ua u cov qauv me me thiab tsim nrog kev ua tau zoo dua qhov ceev hauv siab, uas yog vim li cas lawv feem ntau tau teeb tsa hauv datacenters thiab forenterprise daim ntawv thov.

Cov ntaub ntawv tseeb, ntawm qhov tod tes, tseem nyob tas li txawm tias lawv tau theej qhov twg
Txoj kev twg yog siv rau kev sau khib nyiab hauv Java?
Gc() txoj kev yog siv los hu cov khib nyiab kom meej meej. Txawm li cas los xij gc() txoj kev tsis lav tias JVM yuav ua cov khib nyiab. Nws tsuas yog thov JVM rau kev khaws cov khib nyiab. Txoj kev no muaj nyob rau hauv System thiab Runtime chav kawm
Lub hom phiaj ntawm cov khib nyiab hauv Java yog dab tsi?
Dab tsi yog khib nyiab Collector? Khib nyiab khib nyiab yog ib qho kev pab cuam uas tswj kev nco tau nyob rau hauv de-allocation ntawm cov khoom yog tswj los ntawm Java es tsis yog programmer. Hauv Java programming lus, dynamic faib ntawm cov khoom yog tiav siv tus neeg teb xov tooj tshiab
