Kana bhizinesi richishanda ne data hombe, iyo yekuchengetedza unit inova isiri dhisiki imwe chete, asi seti yedhisiki, kusanganiswa kwavo, kuunganidzwa kwevhoriyamu inodiwa. Uye inofanira kutungamirirwa sechinhu chakakosha. Iyo logic yekuyera kuchengetedza nehombe-block aggregates inotsanangurwa zvakanaka uchishandisa muenzaniso weJBOD - ese ari maviri sefomati yekubatanidza disks uye sechinhu chemuviri.
Iwe unogona kuyera dhisiki zvivakwa kwete chete "kumusoro" nekukanda maJBOD, asiwo "mukati" uchishandisa akasiyana ekuzadza mamiriro. Ngatitarisei kuti izvi zvinoshanda sei uchishandisa iyo Western Digital Ultastar Data60 semuenzaniso.
Nezvekuzadza
JBOD ikirasi yakaparadzana yemidziyo yesevha yekuisa dense yemadhisiki, ine akawanda-channel yekuwana kwavari nemanejimendi mauto kuburikidza neSAS. Vagadziri veJBOD vanovatengesa semadhisiki asina chinhu, zvishoma kana akavharika zvachose - zvichienderana nekuti wasarudza sei. Zvishoma nezvishoma kuzadza chengetedzo nemadhisiki sezvo kudiwa kuri kukura kunobvumidza iwe kuparadzira capital capital nekufamba kwenguva. Zvinobatsira kutenga JBOD nemadhisiki makumi matanhatu kubva kuWestern Digital - yakachipa zvakanyanya. Asi iwe unogona zvakare kutora imwe yakazadzwa zvishoma: iyo shoma gadziriso yeUltastar Data60 ndeye makumi maviri nemana madhiraivha.
Sei 24? Mhinduro iri nyore: aerodynamics. Iyo "goridhe mwero" JBOD 4U / 60 x 3.5 "yatora midzi muindasitiri nezvikonzero zvinoshanda - saizi yemuchina inonzwisisika, kuwana, kutonhora kwakanaka. Madhisiki makumi matanhatu akarongwa semitsetse mishanu yegumi nemaviri HDD imwe neimwe. Mitsetse yakazadzwa zvishoma kana kushomeka kwemadhisiki muJBOD (semuenzaniso, mutsara mumwe chete) zvinotungamira mukupisa kwakashata kana kudzoreredza kuyerera kwemhepo mukati mechiteshi chepakati - chimiro chedhizaini cheUltastar Data60, chimiro chayo chakasiyana.
Mune maJBOD ayo, WD inoshandisa tekinoroji yeArcticFlow disc yekuridza tekinoroji, yakanyatso kutevedzera uye yakasimbiswa. Zvese zveHDDs - zvekuita kwavo, kurarama, uye kuchengetedza data.
Iwo musimboti weArcticFlow unosvika pakuumbwa kwemhepo mbiri dzakazvimiririra dzinoyerera uchishandisa mafeni: yekumberi inotonhodza mitsara yekumberi yemadhiraivha, uye mweya unopinda nemukoridho wemukati wemukati wakadzika mukesi unoshandiswa kuridza madhiraivha kumashure kweJBOD. zone.
Zviripachena kuti sei kuti ArcticFlow ishande nemazvo zvinodikanwa kuve nechokwadi chekuti makamuri asina chinhu akazadzwa. Mukati mekugadzirisa kwemadhiraivha makumi maviri nemana, kurongeka muUltastar Data24 kunofanirwa kutanga kubva kunzvimbo yekumashure.
Muchigadziriso che12-drive, pasina kusangana nekupokana kwaizogadzirwa neaviri-mutsara kurongeka, mhepo inobuda muJBOD inoyerera ichidzoka nepakati penzvimbo yekumberi uye ichipinda muinotonhorera system.
Pane nzira yekuvandudza mamiriro acho - zvimwe pamusoro payo gare gare.
Nezve hybridity
Zvakakodzera kubvuma nekukurumidza seaxiom kuti chinangwa cheJBOD ndechekuchengetera data. Mhedziso kubva pane iyi ndeyekuti: isu tinoishandisa kune huwandu hwevanhu vane homogeneous zvishandiso. Nechinangwa chekupedzisira kusvika kune dhizaini yekuchengetedza vhoriyamu, ichizadza ese macompartments.
Zvakadini neSSDs? Yakanakisa (uye yakarurama) mhinduro ndeyekuvaka yakaparadzana yepamusoro-inoshanda kuchengetedza paJBOF. Solid state avo vanonyanya kugadzikana ipapo. Panguva imwecheteyo, Ultastar Data60 inobvumira kuiswa kwemadhiraivha. Usati watanga JBOD hybridization, iwe unofanirwa kutanga wayera zvakanakira - sarudza SSD kubva pane rondedzero inoenderana (kusiyana neHDD, mamiriro neSSD rutsigiro azere nemanuances). Iwe zvakare uchafanirwa kushandisa mari pakukwira 2,5-inch madhiraivha mu3,5-inch bays.
Single SSD zvishandiso zvinofanirwa kunge zviri kumashure kweJBOD zone, kuvhara makamuri asina kushandiswa nemapulagi akakosha - Dhiraivha Blanks. Izvi zvinovharira kuyerera kwemahara kwemhepo inotonhorera, sezvakataurwa pamusoro, kudzivirira kuti isatendererazve.
Iyo yepamusoro ye24 SSDs inogona kuiswa muUltastar Data60 chassis. Chero zvazvingaitika, iyi inofanirwa kunge iri mitsetse yekupedzisira yenzvimbo yekumashure.
Sei 24? Kupisa kwekupisa kweakasimba-nyika madhiraivha kwakakwira kupfuura hunhu hwakafanana hweHDD, nekuda kweichi chikonzero, mitsara yakawanda-mitsara yemadhisiki ane marudzi akasiyana-siyana enhau haizonyatso kupeperetswa neArcticFlow. Uye kupisa kupisa kuchava njodzi yekushanda kweJBOD.
Izvo zvakakosha kucherechedza pano kuti nekushandisa Drive Blanks unogona kuderedza mhedzisiro yekupisa kwemhepo. Iyo JBOD dhizaini ine gumi nemaviri HDD inotonhorera zvirinani kana iyo isina chinhu compartments yakavharwa nemapulagi. Mugadziri haana kutaura shoko pamusoro pekunyengera kwakadaro, asi kodzero yekuedza ndeyedu nguva dzose. Nenzira, WD hairambidze 12-disc kuzadza, kunyangwe isingakurudzire.
Mhedziso Dzinoshanda
Kunyangwe ruzivo rwepamusoro neiyo aerodynamics yeJBOD inopa pfungwa yekuti kune yakavimbika kushanda kwekuchengetedza zviri nani kuvimba neruzivo uye kurudziro yemugadziri. Maitiro anoitika mukati medhisiki cage anoda tsvakiridzo yakakosha. Kuregeredza ruzivo rwawakawana kuzere nematambudziko, ayo anonzwisisa mupfungwa yese yekuchengetera mavhoriyamu emazana ematerabytes.
Zvinozivikanwa kuti mitemo yemauto inonyorwa sei. Chimwe chinhu chakafanana chinoitika neJBOD architecture. Kana zvigadziriso zvenguva pfupi yapfuura zvakatambura kubva pakurongeka umo chikamu chekubatanidza chakanga chiri munzvimbo ye "exhaust", inoputika nemhepo inopisa, nhasi Ultastar Data60 yakasununguka pane izvi. Zvimwe zvese zvakawanikwa zvekugadzira chingori chishamiso chetekinoroji. Aya ndiwo mabatirwo azvinofanira kuitwa.
