Bake bahlala phezulu esheyini lokudla. Izinkulungwane zeminyaka. Kwabe sekwenzeka into engacabangeki: isibhakabhaka sasimbozwe ngamafu, asaba khona. Ngakolunye uhlangothi lwezwe, kwenzeka izenzakalo ezashintsha isimo sezulu: ukuguquguquka kwanda. Ama-dinosaurs aba makhulu kakhulu futhi anensa kakhulu: imizamo yawo yokuphila yayizohluleka. Ama-apex predators abusa umhlaba iminyaka eyizigidi eziyi-100, ekhula futhi enamandla. Zaguqukela ekubeni yisidalwa esiphelele esiphezulu esheleni lokudla, kodwa umkhathi washintsha ngokuzumayo ubuso beplanethi yethu.
Okuxakayo ukuthi kwakungamafu aqothula ama-dinosaur eminyakeni eyizigidi ezingu-66 edlule. Ngendlela efanayo, amafu namuhla acekela phansi izinhlelo zakudala zokugcina idatha phezulu ochungechungeni lokudla. Kuzo zombili izimo, inkinga kwakungewona amafu ngokwawo, kodwa ikhono lokuzivumelanisa nezwe elishintshayo. Endabeni yama-dinosaurs, konke kwenzeka ngokushesha: umphumela obhubhisayo wamafu wenzeke phakathi nezinsuku noma amasonto okuwa kwe-meteorite (noma ukuqhuma kwentaba-mlilo - ukukhetha kwethiyori kungokwakho). Endabeni yezindawo zokugcina idatha zakudala, inqubo ithatha iminyaka, kodwa, vele, ayinakuhlehliswa.
Isikhathi se-Triassic: iminyaka yensimbi enkulu kanye nokuvela kwezicelo ezifudukayo
Pho kwenzekani? I-ecosystem ekhona yayihlanganisa izinhlelo zokugcina ezisezingeni lokungena nezimaphakathi, amasistimu ezinga lebhizinisi, kanye nesitoreji esinamathiselwe ngqo (DAS). Lezi zigaba zanqunywa abahlaziyi futhi zinenani lazo lemakethe, izinkomba zezindleko, ukwethembeka, ukusebenza, kanye nobukhulu. Kwabe sekwenzeka into eyinqaba.
Ukuvela kwemishini ebonakalayo kwakusho ukuthi izinhlelo zokusebenza eziningi zingasebenza ngesikhathi esisodwa kuseva eyodwa, cishe kubanikazi abaningi—ushintsho oluvele lwangabaza ikusasa lesitoreji esinamathiselwe ngqo. Khona-ke abanikazi bezingqalasizinda ezinkulu ze-hyperscale (ama-hyperscaler): i-Facebook, i-Google, i-eBay, njll., bekhathele ukukhokha imali enkulu yezinhlelo zokugcina, bathuthukise izinhlelo zabo zokusebenza eziqinisekisa ukutholakala kwedatha kumaseva avamile esikhundleni sesitoreji esikhulu "se-hardware". izinhlelo. Khona-ke i-Amazon yethula into engavamile emakethe ebizwa ngokuthi i-Simple Storage Service, noma i-S3. Akuyona i-block, hhayi ifayela, kodwa into entsha ngokuyisisekelo: kwaba nzima ukuthenga uhlelo, kwaba nokwenzeka ukuthenga isevisi kuphela. Ima kancane, kuyini lokho kukhanya okukhanyayo okubonakalayo esibhakabhakeni? Enye i-asteroid?
I-Jurassic: inkathi "ye-saurs enhle ngokwanele"
Singene esigabeni sokuthuthukisa isitoreji ngomcabango wokuthi "okwanele ngokwanele." Amakhasimende esitoreji, ebona lokho okwenziwe ama-hyperscaler, aqala ukungabaza ukulunga kwezindleko eziphindwe kashumi noma eziyikhulu kune-hardware abeyikhokhela kumasistimu abo okugcina ezinkampani. Amalungu afanayo asezingeni eliphakathi aqale ukuzuza isabelo semakethe kusuka ezinhlelweni ezisezingeni eliphezulu. Imikhiqizo efana wabonisa ukukhula ngokushesha. I-EMC Symmetrix, uhlu lwesigaba samabhizinisi olwake lwaba namandla, lwalusabambe indawo ethile, kodwa lwaluncipha ngokushesha. Abasebenzisi abaningi sebeqalile ukuthuthela idatha yabo ku-AWS.
Ngakolunye uhlangothi, abasunguli besitoreji baqala ukuboleka imibono kuma-hyperscalers, besebenzisa ubuchwepheshe bezinhlelo ezisatshalaliswa ezivundlile - umbono ophikisana nokukalwa okuqondile. Kulindeleke ukuthi isofthiwe entsha yokugcina ikwazi ukusebenza kumaseva avamile, njengama-hyperscaler. Azisekho izikhathi ezingu-10-100 zezindleko zemishini ngokwayo. Ngombono, ungasebenzisa noma iyiphi iseva - ukukhetha kuncike kokuncamelayo. Inkathi ye-software-defined storage (SDS) isiqalile: amafu asithe isibhakabhaka, amazinga okushisa ehla, futhi inani lezilwane ezidla ezinye zaqala ukwehla.
Isikhathi seCretaceous: ukuqala kokuvela kwezinhlelo zokugcina ezichazwe yisoftware
Izinsuku zokuqala zesitoreji esichazwe yi-software zazinzima. Kuningi okwathenjiswa, kodwa kuncane okwalethwa. Ngesikhathi esifanayo, ushintsho olubalulekile lwezobuchwepheshe lwenzeka: inkumbulo ye-flash yaba enye yesimanje yokugqwala kokuphotha (HDD). Lesi kwakuyinkathi yokuqalwa kwesitoreji esiningi kanye nemali eyimali yebhizinisi ekulula ukuyiphatha. Konke kungaba kuhle uma kungenjalo ngenkinga eyodwa: ukugcinwa kwedatha kudinga ukucatshangelwa okukhulu. Kuvele ukuthi amakhasimende ayayithanda idatha yawo. Uma belahlekelwa ukufinyelela kuyo, noma amabhithi ambalwa amabi atholakala kuma-terabytes edatha, bayakhathazeka futhi bakhathazeke kakhulu. Iziqalo eziningi azisindanga. Amakhasimende athole ukusebenza okupholile, kodwa akuyona yonke into eyayihamba kahle ngamathuluzi ayisisekelo. Iresiphi embi.
Isikhathi se-Cenozoic: ubukhulu bokugcina bubusa
Bambalwa abantu abakhuluma ngalokho okwenzeka ngemva kwalokho, ngoba akuthakazelisi kakhulu - amakhasimende ayaqhubeka nokuthenga isitoreji sakudala esifanayo. Yebo, labo abathuthele izicelo zabo emafini baphinde bahambisa idatha yabo lapho. Kodwa kuningi lamakhasimende angafuni ukushintshela efwini ngokuphelele, noma angafuni nhlobo ukushintsha, i-Hewlett Packard Enterprise efanayo iqhubekile nokunikeza ama-arrays akudala.
Siku-2019, kungani-ke kusekhona ibhizinisi lokugcina amadola ayizigidigidi elisuselwa kubuchwepheshe be-Y2K? Ngoba ziyasebenza! Kalula nje, izidingo zezinhlelo zokusebenza ezibaluleke kakhulu zemishini zazingafezeki ngemikhiqizo eyakhiwe ngegagasi le-hype. Imikhiqizo efana ne-HPE 3PAR yahlala iyizinketho ezihamba phambili kumakhasimende ebhizinisi, futhi ukuvela okusha kwezakhiwo ze-HPE 3PAR - lokhu kuqinisekisa kuphela.
Ngakolunye uhlangothi, amandla ezinhlelo zokugcina ezichazwe ngesofthiwe ayemahle kakhulu: ukulinganisa okuvundlile, ukusetshenziswa kwamaseva ajwayelekile... Kodwa intengo yalokhu yayiwukuthi: ukutholakala okungazinzile, ukusebenza okungalindelekile kanye nemithetho ethile yokukala.
Ubunkimbinkimbi bezidingo zamakhasimende ukuthi azilokothi zibe lula. Akekho ozosho ukuthi ukulahlekelwa ubuqotho bedatha noma isikhathi sokuphumula esingeziwe kuyamukeleka. Kungakho i-architecture ehlangabezana ngesikhathi esisodwa nezidingo zezikhungo zedatha ezithuthuka ngokushesha futhi, ekusesheni ukuvumelana, ingenazo izici ezibalulekile zesistimu yokugcina yezinga lebhizinisi ibaluleke kakhulu ezinhlelweni zokulondoloza.
Isikhathi semfundo ephakeme: ukuvela kwamafomu amasha empilo
Ake sizame ukuthola ukuthi omunye wabasanda kufika emakethe yokugcina - Datera - wakwazi kanjani ukubhekana nengxube enzima kangaka yezidingo ezisungulwe ngokomlando nezintsha zezinhlelo zokugcina. Okokuqala, ngokuqaliswa kwesakhiwo esigxile ekuxazululeni inkinga echazwe ngenhla. Akwenzeki ukuguqula ukwakheka kwefa ukuze kuhlangatshezwane nezinselelo zesikhungo sedatha sesimanje, njengoba nje kungenakwenzeka ukuguqula isakhiwo sesitoreji esichazwe ngesofthiwe esimaphakathi ukuze kuhlangatshezwane nezidingo zezinhlelo zesigaba samabhizinisi: ama-dinosaurs awazange abe izilwane ezincelisayo ngenxa yezinga lokushisa. iwile.
Ukwakha isixazululo esihlangabezana nezidingo zesitoreji sezinga lebhizinisi kuyilapho usebenzisa ngokugcwele ukushesha kwesikhungo sedatha yesimanje akuwona umsebenzi olula, kodwa yilokho kanye u-Datera ayehlose ukukwenza. Ochwepheshe be-Datera sebeneminyaka emihlanu besebenza kulokhu futhi bathole iresiphi “yokupheka” isitoreji esichazwe ngesoftware esezingeni lebhizinisi.
Ubunzima obuyinhloko i-Datera ehlangabezene nabo ukuthi bekufanele isebenzise u-opharetha onengqondo "FUTHI" esikhundleni se-"OR" elula kakhulu. Ukutholakala okungaguquguquki, KANYE nokusebenza okubikezelwayo, KANYE nokulinganisa kwezakhiwo, KANYE ne-orchestration-as-code, KANYE nezingxenyekazi zekhompuyutha ezijwayelekile, KANYE nokugcinwa kwenqubomgomo, KANYE nokuvumelana nezimo, KANYE nokuphathwa okuqhutshwa ukuhlaziya, ukuphepha “KANYE”, “FUTHI” nokuhlanganiswa ne-ecosystem evulekile. I-opharetha enengqondo ethi “AND” inguhlamvu olulodwa ubude kuno-“NOMA” - lona umehluko omkhulu.
Isikhathi se-Quaternary: izikhungo zedatha zesimanje kanye nokushintsha kwesimo sezulu kungazelelwe kunquma kusengaphambili ukuthuthukiswa kwezinhlelo zokulondoloza ezichazwe ngesofthiwe
Ngakho-ke i-Datera yakha kanjani i-architecture ehlangabezana nezidingo zesitoreji sebhizinisi esivamile ngenkathi ihlangabezana nezidingo zesikhungo sedatha yesimanje ngesikhathi esifanayo? Konke kwehlela kulowo opharetha "FUTHI" oxakile futhi.
Kwakungekho phuzu ekubhekaneni nezidingo zomuntu ngamunye ngamunye. Isamba sezakhi ezinjalo ngeke sibe ingqikithi eyodwa. Njengakunoma yisiphi isimiso esiyinkimbinkimbi, ukucatshangelwa ngokucophelela kwayo yonke inkimbinkimbi yokuvumelana okulinganiselwe kwakubalulekile. Lapho kuthuthukiswa, ochwepheshe be-Datera babeqondiswa izimiso ezintathu eziyinhloko:
- ukuphathwa okuqondene nohlelo lokusebenza;
- indlela ehlanganisiwe yokuqinisekisa ukuguquguquka kwedatha;
- ukusebenza okuphezulu ngenxa yokuncipha kwezindleko eziphezulu.
Isici esivamile salezi zimiso ukulula. Lawula isistimu yakho kalula, phatha idatha yakho kalula ngenjini eyodwa, enhle, futhi ulethe ukusebenza okubikezelwayo (nokuphakama) kuyilapho wehlisa izindleko. Kungani ukulula kubaluleke kangaka? Ochwepheshe be-Savvy emhlabeni wesitoreji bayazi ukuthi ukuhlangabezana nezidingo zesitoreji sesikhungo sedatha esiguqukayo ngeke kufinyelelwe ngokuphathwa kwe-granular, amathuluzi amaningi okuphatha idatha, kanye nokwenza kahle kakhulu ukuze uthole izinzuzo zokusebenza. Inkimbinkimbi yamasu anjalo isivele ijwayelekile kithi njengohlelo lokugcina ama-dinosaur.
Ukujwayelana nalezi zimiso kuyisebenzele kahle iDatera. Isakhiwo abasithuthukisile, ngakolunye uhlangothi, sinokutholakala, ukusebenza kanye nokulinganisa kwesistimu yokugcina yezinga lebhizinisi yesimanje, futhi ngakolunye uhlangothi, ukuguquguquka nesivinini esidingekayo esikhungweni sedatha esichazwe ngesofthiwe yesimanje.
Ukutholakala kwe-Datera eRussia
I-Datera inguzakwethu wezobuchwepheshe womhlaba wonke we-Hewlett Packard Enterprise. Imikhiqizo ye-Datera ihlolelwa ukuhambisana nokusebenza ngamamodeli ahlukahlukene weseva .
Ungafunda kabanzi mayelana nezakhiwo ze-Datera ku Okthoba 31st.
