Kunzima ukucinga ngehlabathi lanamhlanje ngaphandle kokuninzi komxholo wemidiya, oboniswe, phakathi kwezinye izinto, ngohlobo lwedatha yeaudiyo kunye nevidiyo. Kubonakala ngathi mva nje iphupha lokugqibela ibiyingqokelela yeefayile zeMP3. Kwaye namhlanje, iifayile zevidiyo ezinesisombululo se-4K sele zibonwa njengento eqhelekileyo. Yonke le mixholo yemidiya kufuneka yenziwe, ithunyelwe kwenye indawo kwaye emva koko yenziwe ifumaneke kuye wonke umntu. Iinkqubo zangoku zokugcina idatha (kunye kuquka) zifaneleke ngokugqibeleleyo njengenye yezixhobo eziphambili zokusebenza ngomxholo.
Ngokuqinisekileyo, abathengi abaphambili bomthamo kunye ne-bandwidth yamajelo onxibelelwano yidatha yevidiyo. Ukunyuka rhoqo kwisisombululo sesakhelo sevidiyo kwandisa iimfuno zehardware. Ngenxa yoko, izixhobo ebeziseluncedo izolo ziphelelwa lixesha. Emva kwayo yonke loo nto, inguqu eqhelekileyo kwisizukulwana esilandelayo sesisombululo ibandakanya ukwanda okuphindwe kane kwinani lamanqaku kwisakhelo. Ngenxa yoko, umzuzu nje omnye wevidiyo ye-8K engaxinzelelwanga ithatha ngaphezulu kwe-100GB.
Namhlanje, umsebenzi wobuchwephesha onomxholo wevidiyo ocacileyo awuselolungelo lezitudiyo ezinkulu kuphela. Ukuthandwa okukhulayo kochungechunge lweTV, ukusasazwa kunye nenkcazo ephezulu kamabonwakude kutsala abadlali abaninzi ngakumbi kweli shishini. Zonke ezi studio zihlala zivelisa inani elikhulu lezinto "eziluhlaza" ezifuna ukuqhubekeka phambili.
Kwenzeka nje ukuba uninzi lwabasebenzi bemveliso yomxholo ngabantu abanobuchule. Kwaye phakathi kwabo, eyona ndlela iphambili yokusombulula imiba yobugcisa enxulumene nokusebenza kunye nomthamo wediski yayikukuthenga iidrive ezintsha zangaphandle. Njengomthetho, indima yabo idlalwe yimodeli ye-NAS yedeskithophu ene-2-5 disks. Ukukhetha ngenxa yeenkqubo ezilula neziqondakalayo zokusebenza kwabo phakathi kweengcali ezingezizo ezobuchwephesha. Isantya sokusebenza samkelekile xa sisetyenziswa ngabanye njengeDAS (ingakumbi ukuba kukho ujongano olufana neThunderbolt okanye i-USB 3.0). Ukuba ufuna ukwabelana ngedatha, i-NAS (eyaziwa nangokuthi i-DAS) iqhagamshelwe kwenye indawo yokusebenza.
Ngomthamo okhulayo wemithombo yomthombo kunye nokwanda kwenani labasebenzi ababandakanyekayo ekusebenzeni kwayo, le ndlela (masiyibize ngokuthi "yendabuko") ibonisa ngokucacileyo ukungahambisani kwayo. Akunjalo kuphela inani "leebhokisi" ezikhulayo ngokukhawuleza (kwaye ngexesha elifanayo iindleko zokuzithenga), kodwa ukuxhamla kokufikelela kwidatha kuyancipha ngokukhawuleza. Kwaye xa usebenza kunye, iingxaki zivela njenge-cornucopia: ukungqubuzana kokufikelela kwedatha, isantya esinganelanga, njl. Ngoko ke, indlela "yemveli" isanda kutshintshwa yizisombululo zanamhlanje ezisekelwe kwisitoreji esiphakathi (okanye ezininzi zokugcina) kunye nokulungelelanisa ukufikelela okwabelwanayo. kumxholo.
Ewe, ngokuthenga nje Ukutshintshela kumbono omtsha wokusebenza nomxholo awupheli apho. Kwakhona kuya kufuneka ukuba uququzelele ukufikelela okwabelwanayo kwidatha kunye nokuqinisekisa utshintshiselwano olukhawulezayo phakathi kwendawo yokugcina kunye nokucubungula umxholo. Kusenokubakho imizekelo emininzi yokwakha isiseko sokulungiswa komxholo. Ezona ziphambili zezi zilandelayo:
-
Ityala elilula kakhulu kwiistudio ezincinci. Ukulungelelanisa ukufikelela kwidatha, iiprotocol zefayile zisetyenziswa, ukusebenza kwayo kuqinisekiswa .
-
Izitudiyo ezinobungakanani obuphakathi apho kusetyenzwa iiprojekthi ezininzi ngaxeshanye. Apha, ukhetho olufanelekileyo luya kuba kukulungelelanisa ukufikelela kwidatha ngokusebenzisa i-pool yeeseva. Kule meko, kunokwenzeka ukuphumeza ukufikelela kwi-fault-tolerant access to content 24/7 ngokuphindaphinda zonke izinto eziphambili: iiseva, iziteshi zonxibelelwano, ukutshintsha kunye nabalawuli bokugcina. Ukufikelela rhoqo kwidatha kubaluleke kakhulu xa kusetyenzwa imathiriyeli yevidiyo ixesha elide, kuba akukho mntu ufuna ukuphulukana nexesha elininzi, umzekelo, ngenxa yokusilela kwinkqubo yonikezelo. Kwakhona, ukuba une-pool yeeseva, kunokwenzeka ukubonelela ngokulinganisa umthwalo kwiindawo zokusebenza ukuze kuphuculwe ukusebenza ngokubanzi.
-
Izitudiyo ezinkulu, kubandakanywa nezo zijolise kusasazo olubanzi. Kwiiprojekthi ezinjalo, ukunyamezela iimpazamo ngenxa yokuphinda-phindwa kwamacandelo sele kuyimfuneko. Kwakhona, ukukhawuleza, zonke iinkqubo ezingundoqo zokubonelela kunye ne-post-processing ziye zasuswa kwiindawo zokusebenza ukuya kwiiseva ezikhethekileyo ezinokufikelela ngokukhawuleza kwiinkqubo zokugcina ezinomxholo. Ngaphezu koko, ukugcinwa kwedatha yamanqanaba amaninzi kusetyenziswa rhoqo. Ezo. ii-HDD ezicothayo kodwa ezinomthamo zisetyenziselwa ukugcina imathiriyeli yomthombo kunye noovimba, kunye nee-SSD ezikhawulezayo zomsebenzi osebenzayo kunye/okanye ukugcinwa kwi-caching. Ngaphakathi kwesakhelo senkqubo enye yokugcina, amachibi amaninzi enzelwe le njongo evela kwiindidi ezahlukeneyo zemidiya, kunye nezixhobo ezizenzekelayo ezifana ΠΈ . Kwiiprojekthi ezinkulu ngokwenene, ukugcinwa kwamanqanaba amaninzi kufezekiswa ngokusetyenziswa kweenkqubo ezininzi zokugcina, nganye kuzo ezigcinayo. .
Njengomzekelo wokuphunyezwa komsebenzi we-studio yeendaba, singathanda ukukhankanya umbutho wenkqubo yokucubungula umxholo kwesinye sezikhululo zokusasaza zikamabonwakude eTaiwan. Apha, iskimu esaneleyo sokwakha inkqubo, echazwe kumhlathi 2, sisetyenziswa.
Wonke umxholo wemidiya ugcinwa kwisistim yogcino kunye neshelufu yokwandiswa kwe-JBOD . I-chassis kunye neshelufu zixhotyiswe nge-24 NL-SAS drives kunye nomthamo we-14 TB nganye. Ubume besithuba sediski:
- Ugcino - ichibi 24x RAID60
- Ishelufu yokwandisa - 22x RAID60 pool. 2 x eshushu spare
Umncedisi wokunika ufikelelo kwidata liqela leeseva ezi-4 ezisekwe kwiWindows Server. Ukufikelela kumxholo kucwangciswe ngenkqubo ye-CIFS. Ngokwenyama, zonke iiseva ezi-4 zinonxibelelwano kwinkqubo yokugcina ngeFiber Channel 16G ngaphandle kokusetyenziswa kokutshintsha, . Abathengi bafikelela kwi-pool pool ngokusebenzisa inethiwekhi ye-10GbE. Abathengi basebenzisa isoftware ye-Edius v9 kwindawo yeWindows. Iintlobo zomthwalo:
- Sebenza ngevidiyo ye-4K kwimijelo ye-7 - abathengi be-2
- Sebenza ngevidiyo ye-2K ye-13 imilambo - abathengi be-10
Ngenxa yoko, phantsi kwemithwalo ekhankanyiweyo, inkqubo ibonelela ngokusebenza okuzinzileyo okupheleleyo kwe-1500 MB / s, ekhululekile ekusebenzeni kwangoku kwisikhululo sikamabonwakude. Ukuba kuyimfuneko ukwandisa indawo yediski, umthengi ufuna nje ukongeza iishelufu ezongezelelweyo kunye nokwandisa uluhlu olukhoyo kunye neediski ezintsha. Ewe, yonke le misebenzi inokwenziwa kwi-intanethi ngaphandle kokuphazamisa iinkqubo zomsebenzi.
Imidiya isoloko idlala indima ebalulekileyo kubomi boluntu. Namhlanje, oku kuphawuleka ngakumbi kunangaphambili ngenxa yophuhliso losasazo kunye neshishini lokuzonwabisa. Umxholo "onzima" ufuna indlela enzulu xa udala izisombululo zokuyilungisa. Kwaye enye yezinto ezibalulekileyo kwisisombululo esinjalo yi-disk subsystem. Ukugcinwa kuhambelana nale ndima ngokugqibeleleyo, ukubonelela ngokuthembekileyo, ukufikelela kwisantya esiphezulu kunye nokwandiswa okulula kunye nokusebenza.
