Kunzima ukucabanga ngezwe lanamuhla elingenayo inala yokuqukethwe kwemidiya, okwethulwa, phakathi kwezinye izinto, ngendlela yedatha yomsindo nevidiyo. Kubukeka sengathi muva nje iphupho lokugcina bekuyiqoqo lamafayela e-MP3. Futhi namuhla, amafayela evidiyo anesinqumo se-4K asevele abonwa njengento evamile. Konke lokhu okuqukethwe kwemidiya kudinga ukudalwa, kuthunyelwe ndawana thize bese kwenziwa kutholakale kuwo wonke umuntu. Izinhlelo zesimanje zokugcina idatha (kanye kuhlanganise) zifaneleka ngokuphelele njengelinye lamathuluzi ayinhloko okusebenza nokuqukethwe.
Yiqiniso, abathengi abakhulu bomthamo kanye nomkhawulokudonsa weziteshi zokuxhumana yidatha yevidiyo. Ukwanda okuqhubekayo kokulungiswa kohlaka lwevidiyo kukhulisa izimfuneko zehadiwe. Ngenxa yalokhu, imishini ebisabalulekile izolo isiphelelwa yisikhathi ngokushesha. Phela, uguquko olujwayelekile oluya esizukulwaneni esilandelayo sokulungiswa luhlanganisa ukukhuphuka okuphindwe kane kwenani lamaphoyinti kuhlaka. Njengomphumela, umzuzu owodwa nje wevidiyo ye-8K engacindezelwanga ithatha ngaphezu kuka-100GB.
Namuhla, umsebenzi wochwepheshe onokuqukethwe kwevidiyo enencazelo ephezulu awuselona igunya lezitudiyo ezinkulu kuphela. Ukuthandwa okukhulayo kochungechunge lwe-TV, ukusakazwa kwethelevishini kanye nencazelo ephezulu kuheha abadlali abaningi kakhulu kuleli bhizinisi. Zonke lezi zitudiyo zihlala zikhiqiza inani elikhulu lezinto "eziluhlaza" ezidinga ukucutshungulwa okwengeziwe.
Kwenzeka lokhu nje iningi labasebenzi bemboni yokukhiqiza okuqukethwe bangabantu abanobuhlakani. Futhi phakathi kwabo, indlela eyinhloko yokuxazulula izinkinga zobuchwepheshe ezihlobene nokusebenza ngomthamo wediski kwakuwukuthenga amadrayivu amasha angaphandle. Njengomthetho, indima yabo yadlalwa amamodeli wedeskithophu ye-NAS enamadiski angama-2-5. Ukukhetha ngenxa yezinqubo ezilula neziqondakalayo zokusebenza kwabo phakathi kochwepheshe abangewona ochwepheshe. Isivinini sokusebenza samukelekile impela uma sisetshenziswa ngasodwa njenge-DAS (ikakhulukazi uma kukhona ukuxhumana okufana ne-Thunderbolt noma i-USB 3.0). Uma udinga ukwabelana ngedatha, i-NAS (eyaziwa nangokuthi i-DAS) imane ixhumeke kwenye indawo yokusebenza.
Ngomthamo okhulayo wemithombo yomthombo kanye nokwanda kwenani labasebenzi abathintekayo ekucubunguleni kwayo, le ndlela (ake siyibize ngokuthi "yendabuko") ibonisa ngokucacile ukungahambisani kwayo. Akukhona nje kuphela ukuthi inani "lamabhokisi" likhuphuka kakhulu (futhi ngesikhathi esifanayo izindleko zokuwathenga), kodwa ukunethezeka kokufinyelela idatha nakho kuncipha kakhulu. Futhi lapho sisebenza ndawonye, ββizinkinga zivela njenge-cornucopia: ukungqubuzana kokufinyelela kwedatha, isivinini esinganele, njll. Ngakho-ke, indlela "yendabuko" iya ngokuya ithathelwa indawo yizixazululo zesimanje ezisekelwe kusitoreji esimaphakathi (noma isitoreji esiningi) nokuhlela ukufinyelela okwabiwe. kokuqukethwe.
Yiqiniso, ngokuthenga nje Ukushintshela kumqondo omusha wokusebenza nokuqukethwe akugcini lapho. Kuzodingeka futhi ukuhlela ukufinyelela okwabiwe kudatha nokuqinisekisa ukushintshaniswa kwesivinini phakathi kwezindawo zokugcina nokucubungula okuqukethwe. Kungase kube nezibonelo ezimbalwa zokwakha ingqalasizinda yokucubungula okuqukethwe. Eziyinhloko yilezi ezilandelayo:
-
Icala elilula lama-studio amancane. Ukuhlela ukufinyelela kwedatha, kusetshenziswa izivumelwano zefayela, ukusebenza kwazo okuqinisekisiwe .
-
Izitudiyo ezinosayizi omaphakathi lapho kusetshenzwa khona amaphrojekthi amaningana ngesikhathi esisodwa. Lapha, ukukhetha okunengqondo kungaba ukuhlela ukufinyelela kudatha ngokusebenzisa iqoqo lamaseva. Kulesi simo, kungenzeka ukusebenzisa ukufinyelela okubekezelela iphutha kokuqukethwe okungu-24/7 ngokuphindaphinda zonke izingxenye ezibalulekile: amaseva, iziteshi zokuxhumana, amaswishi nezilawuli zokugcina. Ukufinyelela njalo kudatha kubaluleke kakhulu lapho ucubungula izinto zevidiyo isikhathi eside, ngoba akekho ofuna ukulahlekelwa isikhathi esiningi, isibonelo, ngenxa yokwehluleka kwinqubo yokunikezela. Futhi, uma unenqwaba yamaseva, kungenzeka ukuthi unikeze ukulinganisa komthwalo weziteshi zokusebenza ukuze kuthuthukiswe ukusebenza ngokuphelele.
-
Izitudiyo ezinkulu, kuhlanganisa nalezo okuhloswe ngazo ukusakaza kabanzi. Kumaphrojekthi anjalo, ukubekezelelana kwamaphutha ngenxa yokuphindwaphindwa kwezingxenye kakade kufanele kube nakho. Futhi, ukuze kusheshiswe, zonke izinqubo eziyinhloko ezisetshenziswa kakhulu yizinsiza zokuhlinzeka nokucubungula ngemva kokucubungula zisusiwe ezindaweni zokusebenza zayiswa kumaseva akhethekile anokufinyelela okusheshayo okunokwenzeka kumasistimu okugcina anokuqukethwe. Ngaphezu kwalokho, ukugcinwa kwedatha enamazinga amaningi kuvame ukusetshenziswa. Labo. ama-HDD ahamba kancane kodwa anamandla asetshenziselwa ukugcina izinto zomthombo nezingobo zomlando, kanye nama-SSD asheshayo omsebenzi wokusebenza kanye/noma ukulondoloza isikhashana. Ngaphakathi kohlaka lwesistimu eyodwa yokugcina, amachibi amaningana adalelwa le njongo kusukela ezinhlotsheni ezahlukene zemidiya, kanye namathuluzi azenzakalelayo afana ΠΈ . Kumaphrojekthi amakhulu ngempela, ukugcinwa kwamazinga amaningi kufinyelelwa ngokusebenzisa izinhlelo eziningana zokugcina, ngayinye egcina .
Njengesibonelo sokuqaliswa komsebenzi wesitudiyo semidiya, singathanda ukusho ukuhlelwa kwenqubo yokucubungula okuqukethwe kwesinye seziteshi zokusakaza zethelevishini e-Taiwan. Lapha, kusetshenziswe uhlelo olwanele lokwakha uhlelo, oluchazwe esigabeni 2.
Konke okuqukethwe kwemidiya kugcinwa ohlelweni lokugcina kanye neshalofu lokunweba le-JBOD . I-chassis neshalofu kufakwe amadrayivu angama-24 NL-SAS anomthamo we-14 TB ngalinye. Ukucushwa kwesikhala sediski:
- Isitoreji - ichibi le-24x RAID60
- Ishalofu lokunweba - ichibi le-22x RAID60. 2 x okusele okushisayo
I-pool pool yokunikeza ukufinyelela kudatha iqoqo lamaseva angu-4 asekelwe ku-Windows Server. Ukufinyelela kokuqukethwe kuhlelwa ngephrothokholi ye-CIFS. Ngokomzimba, wonke amaseva angu-4 anoxhumo ohlelweni lokugcina nge-Fiber Channel 16G ngaphandle kokusebenzisa amaswishi, . Amaklayenti afinyelela i-pool pool ngenethiwekhi ye-10GbE. Amaklayenti asebenzisa isofthiwe ye-Edius v9 endaweni ye-Windows. Izinhlobo zokulayisha:
- Sebenza ngevidiyo ye-4K ekusakazweni okungu-7 - amaklayenti angu-2
- Sebenza ngevidiyo engu-2K yokusakaza okungu-13 - amaklayenti ayi-10
Ngenxa yalokho, ngaphansi kwemithwalo ecacisiwe, uhlelo luhlinzeka ngokusebenza okuphelele okuzinzile kwe-1500 MB / s, okukhululekile ekusebenzeni kwamanje kwesiteshi sethelevishini. Uma kudingekile ukwandisa isikhala sediski, ikhasimende lidinga nje ukwengeza amashalofu engeziwe futhi andise uhlu olukhona ngamadiski amasha. Yebo, yonke le misebenzi ingenziwa ku-inthanethi ngaphandle kokuphazamisa izinqubo zomsebenzi.
Abezindaba bebelokhu benendima ebalulekile empilweni yomphakathi. Namuhla, lokhu kubonakala kakhulu kunangaphambili ngenxa yokuthuthukiswa kokusakaza kanye nemboni yezokuzijabulisa. Okuqukethwe "okusindayo" kudinga indlela ebucayi lapho udala izixazululo zokucutshungulwa kwakho. Futhi enye yezinto ezibalulekile kusixazululo esinjalo yi-subsystem yediski. Isitoreji siyifanela kahle le ndima, sinikeza ukufinyelela okuthembekile, okunesivinini esikhulu kanye nokwandisa nokusebenza okulula.
