Sekudlule iminyaka emibili saqala ukuhlinzeka ngezinkundla (izikhathi ezi-2 eziphansi kunesilinganiso semakethe), ngoba ekuthengeni, ngisho namanje, lapho isizukulwane sakamuva se-E5-2650 v4 processors kuthiwa ukuphela kwempilo ngumenzi, kubiza ama-euro angu-8500 + 21% VAT = 10285 euros (isikhathi sokukhokha 5.7 iminyaka, uma sicabangela izindleko zokubeka indawo kanye nethrafikhi futhi singazicabangeli izindleko zezindleko zokusekela):
Senze ngempumelelo izixazululo eziningi zeqoqo kulezi zinkundla zababhalisile bebhizinisi lethu, kanye nabasebenzisi abangabodwana. Sithuthukise futhi sethula ngempumelelo umkhiqizo owengeziwe - amaseva abonakalayo anesitoreji esizinikele, okwenza kwaba nokwenzeka ukufaka esikhundleni umugqa wokuqala wamaseva azinikezele futhi sinikeze amaseva e-VPS ngezinsiza ze-10-40GB DDR4 RAM, 6-24 E5-2650 v4 cores, kanye okubaluleke kakhulu - 1- 4 ozinikele ngokugcwele 4TB HDD noma 240-480GB SSD oshayelayo. Sichaze ngokuningiliziwe izinzuzo kanye nokubi zalo mkhiqizo lapha: (Izinketho ezine-RAID1 ne-RAID10 ziyatholakala).
Futhi konke kubonakala kuhamba kahle, safeza uhlelo lokuthengisa, sathengisa ngisho nangaphezu kwalokho obekuhleliwe, izinkulungwane zabasebenzisi zathenga izixazululo zethu ezibonakalayo, ngenxa yokuthi sacishe salahla ngokuphelele amaseva aphelelwe yisikhathi nge-E3-1230 kanye ne-E5620 processors, eya-odwa. ngalabo ababhalisile abangazange bakwazi ukukhokhela i-Dell R730xd, nakuba siyenze yashibha ngangokunokwenzeka. Phela, manje sebengakwazi ukukhokhela, bathi, le VPS (KVM) - E5-2650 v4 (24 Cores) 40GB DDR4 ene-4x240GB RAID10 SSD noma 4x4TB RAID10 HDD 1Gbps 40TB ngentengo ye-E3-1230 efanayo. Kungani kungekona ukumiselela okuhle kwe-E3-1230 ephelelwe yisikhathi enesethi efanayo yamadiski? Noma baze bakhetha inketho enezinsiza eziphindwe izikhathi ezi-2 (lapho izinsiza eziningi zingadingeki), futhi balondoloze ngaphezu kwengxenye yesabelomali. Ngenxa yalokho, asizange nje sinciphise izindleko zikagesi nokugcinwa, ngoba i-hardware entsha ihluleka kaningi futhi ayihluleki, inamandla kakhulu, ababhalisile abaningi bangafakwa kumayunithi ambalwa, kodwa okubaluleke kakhulu, sandise izinga lamakhasimende. ukwaneliseka ngenkonzo yethu.
Nokho, asikwazanga ukwanelisa izidingo zengxenye encane yababhalisile. Phela, kwakungenakwenzeka ukudala indawo ebonakalayo egcwele ngokugcwele endaweni ekhona kakade (yize amaqhinga athile asetshenziselwa lokhu ngendlela ye-Dockers nezinye izinto) + RAM "kuphela" kuze kufike ku-40GB (le nkinga yayiyingxenye. ilungiswe umkhiqizo we-NVM), ayikho indlela yokukhetha izinga le-RAID oyifunayo noma ukhuphule isilinganiso se-SSD, kuyilapho empeleni sibeke amaklayenti angu-2 kuphela kumayunithi angu-3. Ngokuvamile, kwakukhona ukushiyeka, isixazululo kwakungewona wonke umuntu.
Mhlawumbe ngizovula amehlo abanye, kodwa eNetherlands, izikhungo eziningi zedatha ezinkulu azinayo i-hardware yazo, ngenxa yentela enkulu ephakama lapho umnikazi futhi uyithenga. Yonke into ingaphansi kwesikhathi eside (inkontileka yeminyaka eyishumi noma ngaphezulu) evela kumkhiqizi (i-Dell, HP, Supermicro). Okukhawulela kakhulu. Phela, ukuze siqinisekise izindleko eziphansi kakhulu, kwakudingeka sishiye yonke i-zoo yokucushwa futhi sisayine eyodwa, inkundla esebenza kahle kakhulu yawo wonke umuntu. Futhi sisebenzise amakhono enkundla kuze kube sezingeni eliphezulu, sihlangabezana nezidingo zababhalisile abangaphezu kuka-95%.
Kodwa abakwazanga ukuyixazulula ngokuphelele inkinga. Futhi "ngaphezu kuka-95%" wamakhasimende wamanje awaphikisani nentuthuko. Yiqiniso, akunzima ukufaka okunye ukucushwa, kodwa umbuzo wonke uyintengo. Siqhudelana kanjani neminikelo emikhulu enezindleko eziphansi kuyilapho sisanikeza ihadiwe yekhwalithi ephezulu kanye nenani eliphezulu ngentengo efanayo noma ephansi?
NgoJanuwari walo nyaka, savula ihhovisi lethu elimele i-European SIA UA-Hosting eLatvia ngale njongo. Lokhu akukhulisanga nje kuphela ukuthi kube lula ukusebenza nathi kwababhalisile bebhizinisi, kodwa futhi kwenze kwaba nokwenzeka ukuqala ukubuyisela i-VAT ekuthengweni, okuphinde kwehlise kakhulu inani lentengo. Ngemva kwesikhathi esithile, ngokuqinisekile sizokwabelana ngolwazi lwethu. Kuzoba nendatshana ehlukene enemininingwane yokuthi kulula kangakanani ukubhalisa manje eYurophu, esikhundleni seBelize, nokuthi kunzima kangakanani ukuvula i-akhawunti yasebhange ezweni lokubhalisa, noma ngabe unayo yonke imibhalo edingekayo yalokhu. Azikho izinkampani ezikusiza namuhla ezokunikeza i-akhawunti yasebhange eLatvia yenkampani yaseLatvia, wonke umuntu uzonikela ngeSwitzerland futhi uzofuna ama-euro angama-4000 ukuze uthole usizo lokuvula i-akhawunti, okungeke kube lula ikakhulukazi kamuva uma wamukela i-PayPal ngokuqondile ( kuzoholela kumakhomishana engeziwe futhi amanani ekugcineni azofinyelela amashumi ezinkulungwane zama-euro ngonyaka, kuye ngenzuzo yakho, njengoba amakhomishini engeziwe asetshenziswa uma i-akhawunti yakho ingekho ezweni lokubhalisa).
Kodwa namuhla ake siqhubeke mayelana nehadiwe. Sicabange isikhathi eside futhi kanzima mayelana nesixazululo se-1U esingasinikeza. Iluphi uhlobo lweseva olunganelisa ngokugcwele izidingo zamaklayenti angu-5% futhi lwandise ngokuphawulekayo amakhono amanje?
Sachitha izinyanga ezimbalwa sicabanga, sikhetha, futhi sihlola. Sikuqhathanise inkomba eyongayo. Yiqiniso, angeke kube khona lutho olungcono kune-Dell R730xd okwamanje :) Ngaphandle kwalokho, besingeke siqhubeke sinikeza lezi zixazululo, futhi ngendlela, saqala ukwenza lokhu ngama-processor abuyekeziwe, okuyi-Tetradeca Core, hhayi i-Dodeca, okungukuthi, ama-cores angu-14 agcwele ngokugcwele ku-processor ngayinye, i-28 icabangela i-hypertrading, ngisho nama-frequencies we-2.6 GHz, esikhundleni se-2.2, futhi baze banquma ukwehlisa intengo, bebeka imishini ngesikhathi esifanayo. , kodwa ngokuyisisekelo inikela nge-64GB DDR4 RAM kuphela, hhayi i-128, ngoba akuwona wonke umuntu odinga lokho okuningi:
I-Dell R730xd - 2x E5-2697v3 2.6GHz 14C 64GB DDR4 4x960GB SSD 1Gbps 100TB - $199 / ngenyanga, nakuba ukhokha iminyaka engu-2, nyanga zonke futhi uma ukhokha unyaka kuzobiza kakhulu, noma kunjalo, bheka ukuthi muhle kangakanani. :
Sisebenzisa i-Fortigate ukuze sihlele ukufinyelela okuphephile kweklayenti ngalinye kuseva eqashisayo ye-iDrac. Ngenxa ye-Forticlient, unokufinyelela kunethiwekhi yangaphakathi, futhi yonke enye ithrafikhi yakho ngeke idlule emhubheni we-VPN, kuphela ithrafikhi eya kunethiwekhi yangaphakathi izodlula kuyo, okuyinto elula kakhulu, ngokungafani ne-VPN evamile. Sixhuma wonke amaseva kuma-PDU amabili azimele (asiqedi amasokhethi):
Ukushintsha kwe-rack ngakunye kuxhunywe izixhumanisi ze-fiber optic ezingu-2x10G ekushintsheni kokusabalalisa, ithrafikhi esuka lapho ihanjiswa ngama-cores amabili azimele esikhungo sedatha. Okungukuthi, asizange nje sinikeze intengo izikhathi ezi-2 eziphansi kunentengo yemakethe, kodwa futhi sinike inethiwekhi ye-premium ngentengo efanayo. Ithrafikhi ye-inthanethi ilethwa abahlinzeki bezokuthutha be-Tier I njenge-GTT ne-NTT, ngakho ukuxhumeka ngaphandle kokubhuka kubiza cishe ama-euro angu-7000 ku-10G esikhungweni sedatha ngokuqondile, kodwa sinikeza i-2N ngentengo eshibhe izikhathi ezingaphezu kwezingu-2, igigabhithi ngayinye eyengeziwe ingu-$450. Yebo, yiqiniso, le ntengo ihlanganisa iqiniso lokuthi akuwona wonke amaklayenti azosebenzisa umkhawulo wawo ngokugcwele, yingakho "sibeke engozini" ngokunikeza inani elinjalo. Izibalo - iminyaka eminingi yesipiliyoni sangempela. Amaseva angu-500 anoxhumo lwe-gigabit kanye nomkhawulo wethrafikhi we-100 TB adla ngokwesilinganiso cishe u-20 Gbit/s (hhayi u-160-200 Gbit/s, njengoba umuntu angase acabange), lena idatha yangempela. Vele, ababhalisile abaqale badle kakhulu uma be-oda i-Unmetered abacatshangelwa. Ukuthi nje akubona bonke abantu abadla i-TB yabo eyi-100, yingakho singesabi ukuthengisa ithrafikhi yabantu ngamanani aphansi kunaleso lapho umhlinzeki wezokuthutha ethengisa khona ukuxhumana.
Phakathi kwezinye izinto, sinikeza ababhalisi bethu i-1G noma i-10G LAN, kanye namakheli e-IP avela kumanethiwekhi e-RU GEO noma e-NL kanye nekhono lokusebenzisa izinqamuleli zomlilo zehadiwe namaswishi ayimfihlo. Kodwa-ke, naphezu kokuthi sinikeze amaseva ngentengo ephansi izikhathi ezingaphezu kwezingu-2 kunentengo yemakethe, futhi sicabangela inethiwekhi ye-premium - izikhathi ezi-3-4 eziphansi kunentengo yemakethe, kusekhona ingxenye echazwe ngenhla yamakhasimende. abangakwazi ukukhokhela iseva enjalo, kodwa i-VPS (ingxenye yesithathu yesiphakeli somzimba) ayigculisi ngezizathu ezihlukahlukene.
Sichithe isikhathi eside sikhetha ukucushwa okungcono kakhulu, njengoba sisafuna ukunikeza βokushaβ, kodwa ngesikhathi esifanayo kungabizi kakhulu, futhi safinyelela esiphethweni sokuthi kungcono sinikeze i-128GB DDR3 RAM kune-64GB DDR4. Kungani?
- ukusebenza ngemvamisa efanayo ye-2400 MHz, DDR3 kanye ne-DDR4 izinti zememori zibonisa imiphumela efanayo;
- I-latency ye-DDR4 kuleli cala ingama-nanoseconds angu-15, futhi i-DDR3 - 11 nanoseconds, okungukuthi, kumafrikhwensi anjalo, inkumbulo ye-DDR3 nayo "iyashesha" ngokuya ngokubambezeleka;
- Noma yiziphi izinzuzo ze-DDR4 ziqala ukubonakala kuphela kumafrikhwensi angaphezu kuka-3000 MHz, okungadingeki kuwo wonke umsebenzisi; ngezinye izikhathi ukubambezeleka kubaluleke kakhulu.
Umehluko phakathi kwe-DDR3-2133 kanye ne-DDR4-2133 ubonakala ungabalulekile ezinhlelweni eziningi, okuhlanganisa namacala okuguqulwa kwevidiyo. I-DDR3 ishesha ngaphezu kwengxenye yamacala.
Futhi njengoba umgomo wethu kwakuwukunikeza inkundla yezindleko ezincane, kodwa ngesikhathi esifanayo kubiza ngempumelelo, sanquma ukuzama ukunikeza inketho elandelayo eNetherlands kusukela ku-$ 99 / ngenyanga (intengo ye-VPS):
I-Dell R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 2x960GB SSD 1Gbps 100TB - oda
Okokuqala, sifuna ukutadisha isidingo, sikubuze ukuthi senze iphutha? Sesivele sikufakele amapulatifomu amaningana anjalo endaweni yokubeka amaseva e-1U (futhi sisenokulinganisa endaweni ukuze singahlanganisi amapulatifomu ahlukene endaweni eyodwa ngokubheka ukusetshenziswa kahle kwemishini yenethiwekhi namandla) futhi siqeda ukwakhiwa kwayo. :
Ukucushwa kusekela amadrayivu angama-8 SSD kuze kufike ku-2 PCIe NVMe (uma inethiwekhi ye-10G idingeka, khona-ke idrayivu eyodwa, njengoba ikhadi le-10G elinezimbobo ezimbili lizothatha elinye lamachweba). Sinqume ukunganikezeli ngama-HDD adla amandla futhi ahamba kancane ngalokhu kumisa, kodwa ukuhlinzeka ngama-Samsung 960GB (MZ7LH960HAJR) amabili ngentengo enhle. Lapho ukhokhela iseva isikhathi esingaphezu konyaka, amadrayivu engeziwe ashibhe izikhathi ezi-2, kuphela +$25/ngenyanga ngedrayivu ngayinye. Yebo, ngo-$249/ngenyanga ungathola cishe isilinganiso esingu-8 TB SSD kanye neseva enhle ye-Dell R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 8x960GB SSD 1Gbps 100TB.
Idrayivu eyengeziwe engu-1Γ3.2TB PCI-E Samsung PM1725b SSD izobiza β +$250 / ngenyanga (kufanele okungenani sizuze imali kokuthile iminyaka engaphezu kwengu-5.7), kodwa izaphulelo zingenzeka ekuqashweni kwesikhathi eside. Kungani sifaka futhi sinikela ngamadrayivu anjalo kuphela, hhayi i-NVMe hot-swap M2? Lawa madrayivu asengcono, ukubambezeleka kuphansi izikhathi eziningi ngenxa yokuxhumeka kwe-PCI-E. Lawa amadrayivu asetshenziswa, ake sithi, amabhange noma amaklayenti asebenzisa uhlobo oluthile lokucubungula. Ama-M2 awasebenzi kahle kakhulu kule misebenzi. Futhi nakuba kunamadrayivu angu-1.6 TB kanye ne-6.4 TB emakethe, isizathu sokungawasebenzisi silula. Endabeni ye-1.6 TB, ivolumu incane kakhulu, izikhala ze-PCI-E zingasetshenziswa ngokushesha, futhi esimweni se-6.4 TB, inqubo yokutakula izothatha isikhathi eside kakhulu, ngakho-ke i-3.2 TB yakhethwa ngokufanelekile ngokuthi "igolide". kubi".
Siphinde sinake okubalulekile entweni efana nekhebula. Phela, ubuhle bokubekwa kwekhebula bunquma ukuthi inyakatho izopholiswa kanjani kanye nokusetshenziswa kwamandla okwenzeka ngenxa yale nqubo. Ngokuhlanganisa izintambo ngamaqembu, sinciphisa indawo "yokuvimbela" endleleni yomoya oshisayo futhi ichithwa ngokuphumelelayo kusuka kuma-racks, njengoba i-turbulence ephazamisa ukukhishwa kokushisa okuphumelelayo kuyancishiswa.
Sekukonke ngikholwa ukuthi ukucushwa kube yimpumelelo. Kodwa-ke, sikulungele ukulalela ukugxekwa ngalesi siphakamiso esivela kubafundi be-Habr, phela, kaningi, ngokuveza imibono, usiqondise endleleni efanele, futhi sinentshisekelo yokukunikeza izixazululo ezisebenza kahle kakhulu esikhathini esizayo. Ngiyabonga kakhulu kusengaphambili ngalokhu! Okunikezwayo kunomkhawulo ngobuningi futhi njengamanje sinamaseva angu-16 e-Netherlands. Angikushiyi ngaphandle ukuthi esikhathini esizayo, intengo yama-oda amasha ingase ibe phezulu, kodwa manje unethuba elihle kakhulu lokuhlela iseva ngentengo ephansi kakhulu (eqinisweni, ngezindleko zokuhlukaniswa, ngenxa yazo zonke izinzuzo. kuchaziwe).
Akusho ukuthi kubasebenzisi bakwa-Habr kukhona ibhonasi enhle - +1 inyanga mahhala uma ukhokhela i-Dell R420 isikhathi esiyizinyanga ezi-3 noma ngaphezulu. (ukuthola ibhonasi, vele ushiye inombolo yakho ye-oda lapha kumazwana futhi ube umsebenzisi obhalisiwe we-Habr). Ngakho-ke, unethuba lokusebenza izinyanga ezingu-4 zokuqala ngentengo ye-$ 119, uhlole ikhwalithi, bese ushintshela emjikelezweni wokukhokha weminyaka emibili, ukhokhela insizakalo iminyaka engu-2 futhi uthole intengo eyingqayizivele ye-$ 99 / ngenyanga. ngeseva ngayinye!
Sisebenza ngokomzimba abantu nezinhlangano ezisemthethweni abantu abavela eRussian Federation, Ukraine kanye nomhlaba wonke ngaphansi kwesivumelwano; izivumelwano ziphothulwa phakathi kwethu (i-SIA UA-Hosting, Latvia) kanye nenkampani yakho. Xhumana nathi, sizokujabulela ukubambisana!
