Isizathu solwazi sokubhala lesi sihloko bekuwusekelo olusemthethweni oluvela ku-Qsan lokuxhuma amashalofu okunweba enkampani yangaphandle kumasistimu okugcina. Leli qiniso liyagqama phakathi kwabanye abathengisi futhi ngisho ngezinga elithile iphula isikhundla esivamile emakethe yokugcina. Kodwa-ke, kithina kubonakala sengathi bekungemnandi kangako ukumane ubhale ngohlelo lokugcina lwe-Qsan + "alien" JBOD kunokuthinta isihloko esiphelele sokusebenzisa izingxenye zenkampani yangaphandle.
Isihloko sokungqubuzana phakathi kwabathengisi besitoreji (kanye nezinye izisetshenziswa ze-Enterprise) nabasebenzisi babo abafuna ukusebenzisa izingxenye zezinkampani zangaphandle sizoba ingunaphakade. Phela imali iyona ewumgogodla wokungqubuzana. Futhi ngezinye izikhathi imali eningi. Iqembu ngalinye linezimpikiswano ezikholisayo ezivuna umbono walo futhi ngokuvamile lithatha izinyathelo ezithile ukuze leli phuzu lokubuka kube yilona kuphela elilungile. Ake sizame ukuthola ukuthi kungenzeka yini ukuthi kube nokuvumelana, ukuze bobabili abathintekayo baneliseke.
Izimpikiswano ezijwayelekile zomthengisi wesitoreji ezidinga ukusetshenziswa okuyisibopho kwezingxenye ezinophawu "zabo" ngokuvamile yizi ezilandelayo:
- Izingxenye "ezingezakho" zihambisana 100% namasistimu okugcina. Ngeke kube nezimanga. Futhi uma ziphakama, umthengisi uzozixazulula ngokushesha ngangokunokwenzeka;
- Ukwesekwa okukodwa kanye newaranti yaso sonke isisombululo.
Konke lokhu kuhumusha ukuthi izindleko zezingxenye ezinophawu ngezinye izikhathi zidlula kakhulu izindleko zemikhiqizo efanayo ethengiswa emakethe yamahhala. Futhi abasebenzisi, yiqiniso, banesifiso "sokukhohlisa uhlelo" ngokushelela izingxenye ezingahloselwe ngokusemthethweni izinhlelo zokugcina. Kuyaphawuleka ukuthi hhayi kuphela izingane zesikole izolo, kodwa futhi izinhlangano ezingathi sína waqaphela ngemuva izenzo ezinjalo.
Izingxenye zezinkampani zangaphandle ezidume kakhulu ezifuna ukuzifaka ezinhlelweni zokugcina ngamadrayivu akude. Lokhu kungenxa yokuthi izindleko zama-brand discs zilula kakhulu ukuqhathanisa nozakwabo besitolo. Ngakho-ke, emehlweni abasebenzisi, kumanani abo lapho "ukuhaha" komthengisi kufihliwe.
Ngokwengxenye yabo, abathengisi besitoreji abakwazi ukubuka nje izenzo zabasebenzisi ezingekho emthethweni ngokombono wabo futhi ngazo zonke izindlela ezingenzeka bafake ama-spokes kumasondo abo. Lapha, kukhona ukukhiya komthengisi ezingxenyeni "zabo", nokwenqaba ukusekela idivayisi uma kusetshenziswa amadiski angekho emthethweni (ngisho noma inkinga isobala futhi ayihlangene nabo).
Ngakho ingabe umdlalo ulifanele ikhandlela? Ake sicabangele ukuthi kungenzeka yini ukuwina kulesi simo futhi yiziphi izindleko.
100% iyahambisana
Masithembeke, sivume ukuthi inani labakhiqizi bangempela be-HDD ne-SSD drives lincane. Uhlu lwazo zonke lunomkhawulo futhi alubuyekezwa ngesivinini se-cosmic. Ngakho-ke, uma kungenjalo konke, khona-ke okungenani ingxenye ebalulekile yamadrayivu ingase ihlolwe ngumthengisi wesitoreji. Leli qiniso liqinisekiswa ukusekelwa kwamadrayivu ezinkampani zangaphandle ohlwini lwazo oluhambisanayo ngabathengisi abaningi abadumile besitoreji. Ngokwesibonelo, at .
Ukusekela kanye newaranti yesixazululo sonke
Ushizi wamahhala, uyazi ukuthi ukuphi. Ngakho-ke, ukwesekwa komthengisi (hhayi nje ukusekelwa kwewaranti) akulokothi kube mahhala.
Lapho uthenga amadrayivu eceleni, udinga ukulungela iqiniso lokuthi, uma kunezinkinga ngawo, umsebenzisi uzodinga ukuxazulula izinkinga nomphakeli wakhe (abathengisi bedrayivu abavamile ukunikeza ukusekelwa kwabo kubasebenzisi babo). Kuyiqiniso impela ukuhlangana, ngokwesibonelo, isimo lapho idiski yenqatshwa uhlelo lokulondoloza ngesikhathi sokusebenza, kodwa umphakeli uyayibona njengesevisi. Futhi, isivinini sokushintsha idrayivu enephutha sizolawulwa ubudlelwano bomthengi nomthengisi. Futhi ayitholakali neze ngokushesha ngangokunokwenzeka.
Uma umsebenzisi ekulungele ukubekezelela imikhawulo enjalo, ungazama "ukuzibekela utshani." Ngokwesibonelo, thenga ama-backup disks kusengaphambili. Izenzo ezinjalo, yiqiniso, zizodinga ukutshalwa kwezimali okwengeziwe, kodwa kwezinye izimo zizohlala zikhanga ngokwezimali.
Ngemuva kwazo zonke lezi zingxabano mayelana nokusetshenziswa kwezingxenye ezihambisanayo, umuntu akufanele akhohlwe ukuthi kungani, empeleni, konke lokhu kwaqalwa. Isitoreji singelinye lamathuluzi ebhizinisi. Futhi ithuluzi ngalinye kufanele lisebenzise izimali ezitshalwe kulo ngo-146%. Futhi noma yiluphi uhlelo olulula lokugcina, futhi ngisho nangaphezulu ukulahlekelwa kwedatha kuyo, kumane kuwukunethezeka okungathengeki kanye nokulahlekelwa okukhulu kwemali. Ngakho-ke, lapho wenza isinqumo sokusebenzisa amadiski angaqinisekisiwe ukuze wonge imali, kufanelekile ukukhumbula imiphumela emibi yezenzo zakho.
Ngaphandle kokungabaza, bheka kungcono "ukuthenga" ngezindlela eziningi. Kodwa, njengoba umkhuba ubonisa, empilweni yezinkampani zanoma yisiphi isayizi kunezikhathi lapho zingekho khona izimali eziningi zokuthuthukiswa kwengqalasizinda ye-IT njengoba singathanda. Ngakho-ke, ikhono lokusebenzisa kuyinto plus enkulu. Inzuzo esobala yezinhlelo zokugcina ezisekela kanyekanye ukusetshenziswa kwakho kokubili “okwakho” namadrayivu ahambisanayo ukuguquguquka ekwenzeni izinqumo kanye nokunciphisa ubungozi bakho ngesikhathi sokusebenza.
Futhi uma ungamangali noma ubani ngokusekelwa amadiski ezinkampani zangaphandle (ake sithembeke: akuyena yedwa umthengisi ovumela lokhu). Okusho ukuthi, ukusekelwa kwamashalofu okunweba e-JBOD kubo bonke abathengisi kuhlale kunqunyelwe kumamodeli abo kuphela. Yebo, kwezinye izimo, amanye amashalofu awo awumphumela wokubambisana kwe-OEM phakathi komthengisi wesitoreji nomunye umenzi. Kodwa ama-JBOD anjalo ahlala enenguqulo yawo ye-firmware eyingqayizivele (kuhlanganise nokuqaliswa kokukhiya komthengisi), athengiswa ngeziteshi zomthengisi wesitoreji futhi ahlinzekwa ngokusekelwa kwawo. Icala le-Qsan lihlukile ngoba ngamashalofu “angaphandle” asekelwayo. Amamodeli alandelayo njengamanje anesimo esihambisanayo:
- I-Seagate Exos E 4U106 - 106 LFF ishayela ku-chassis engu-4U
- I-Western Digital Ultrastar Data60 - 60 LFF ishayela ku-chassis engu-4U
- I-Western Digital Ultrastar Data102 - 102 LFF ishayela ku-chassis engu-4U
Wonke amashalofu asekelwayo Aminyana Kakhulu. Kuyaqondakala: ukudala ukuncintisana nochungechunge lwakho lwe-JBOD ngokusobala akuhleliwe. Ngasikhathi sinye, ngamashalofu anjalo impela, yize engadingeki kaningi njengama-JBOD wefomu elijwayelekile, kodwa asadingeka emisebenzini eminingana edinga inani elikhulu lokushayela.
Njengamadrayivu, abasebenzisi banokukhetha ukuthi bangathenga kuphi futhi kanjani i-JBOD ehambisanayo. Uma udinga ukusekelwa ukuze uthole isisombululo esiphelele, kufanele uxhumane no-Qsan. Uma usukulungele ukuxazulula izinkinga zewaranti kubathengisi abahlukene, ungathenga i-JBOD eceleni. Kunoma yikuphi, lapho uhlela ukusebenzisa amashalofu ezinkampani zangaphandle, kufanele ufunde ngokucophelela amadokhumenti afanele, abonisa ukulinganiselwa ekucushweni okungenzeka kanye nezidingo ze-hardware/software yazo zonke izingxenye.
Futhi, ukubuyela endabeni yokukhetha "umngane / isitha" maqondana ne-JBOD, kufanelekile ukusho ukuthi ukusebenzisana akunqatshelwe. kanye nabakhiqizi bezinkampani zangaphandle ngaphakathi kwesistimu eyodwa. Ngakho-ke, ngesikhathi sokusebenza, ungasondela ngokuguquguqukayo endabeni yokwandisa umthamo, kuye ngezidingo zamanje namandla ezezimali.
Esikhundleni salokho okucatshangwa kabi kwamanye amakhasimende ukuthengwa kwesistimu yokugcina impahla kumthengisi othile futhi azame futhi ukuyihlomisa ngezinto ezingahambelani ukuze wonge imali. Ngempela, kulokhu, iphuzu lonke lokuba nesistimu yesitoreji enjalo livame ukulahleka, ngoba. ngeke kube nokusekelwa okugcwele okuvela kumthengisi. Kunengqondo kakhulu ukukhetha umthengisi wesitoreji ongenayo le mikhawulo. kungumthengisi onjalo, oshiya abasebenzisi ukuthi bazinqumele ukuthi yiziphi izingxenye abazozisebenzisa nokuthi bazithenge kuphi.
