Ngaphezu kweminyaka emibini sele siqalile ukubonelela ngamaqonga (Amaxesha ama-2 angaphantsi kunomyinge wemarike), kuba ekuthengeni, nangoku, xa isizukulwana samva nje i-E5-2650 v4 iprosesa ibhengezwa njengokuphela kobomi ngumenzi, zibiza i-8500 euro + 21% VAT = 10285 euro (ixesha lokubuyisela i-5.7 iminyaka, ukuba sithathela ingqalelo indleko ye-colocation kunye ne-traffic kwaye singathatheli ngqalelo iindleko zenkxaso konke konke):
Siphumeze ngempumelelo izisombululo ezininzi zeqela kula maqonga kubabhalisi bethu beshishini, kunye nabasebenzisi ngabanye. Siphuhlise kwaye siqalise ngempumelelo imveliso eyongezelelweyo - iiseva ezibonakalayo ezinokugcinwa okunikezelweyo, okwenza kube lula ukubuyisela umgca wokuqala weeseva ezinikezelweyo kunye nokubonelela ngeeseva zeVPS ngezibonelelo ze-10-40GB DDR4 RAM, 6-24 E5-2650 v4 cores, kunye okona kubaluleke kakhulu - 1- 4 ezinikele ngokupheleleyo 4TB HDD okanye 240-480GB SSD drives. Sichaze ngokweenkcukacha izinto eziluncedo kunye nezingeloncedo zale mveliso apha: (Ukhetho nge-RAID1 kunye ne-RAID10 ekhoyo).
Kwaye yonke into ibonakala ilungile, sizalisekise isicwangciso sokuthengisa, sathengisa nangaphezulu kunokuba bekucwangcisiwe, amawaka abasebenzisi athenge izisombululo zethu ezibonakalayo, enkosi apho siphantse sazilahla ngokupheleleyo iiseva eziphelelwe lixesha kunye ne-E3-1230 kunye neeprosesa ze-E5620, eziyalelweyo. ngabo babhalisi abangakwaziyo ukuthenga iDell R730xd, nangona siye sayenza yangabizi kakhulu. Ngapha koko, ngoku babenako ukuthenga, bathi, le VPS (KVM) - E5-2650 v4 (24 Cores) 40GB DDR4 kunye 4x240GB RAID10 SSD okanye 4x4TB RAID10 HDD 1Gbps 40TB ngexabiso efanayo E3-1230. Kutheni ingelulo ukutshintshwa kakuhle kwe-E3-1230 yakudala eneseti efanayo yeediski? Okanye bade bakhetha ukhetho kunye namaxesha e-2 angaphantsi kwezibonelelo (xa izibonelelo ezininzi zingafunwa), kwaye zigcinwe ngaphezu kwesiqingatha sohlahlo lwabiwo-mali. Ngenxa yoko, asizange sinciphise kuphela iindleko zombane kunye nokugcinwa, kuba i-hardware entsha iyasilela kaninzi kwaye inqabile, inamandla ngakumbi, ababhalisi abaninzi banokubekwa kwiiyunithi ezimbalwa, kodwa okona kubaluleke kakhulu, sandise iqondo lomthengi. ulwaneliseko ngenkonzo yethu.
Noko ke, asikwazanga ukwanelisa iintswelo zenxalenye encinane yabantu abarhumelayo. Emva kwayo yonke loo nto, kwakungenakwenzeka ukudala indawo egcwele ngokupheleleyo kwindawo esele ikhona (nangona amaqhinga athile asetyenziselwa oku ngendlela yeeDockers kunye nezinye izinto) + RAM "kuphela" ukuya kuthi ga kwi-40GB (le ngxaki yayiyinxenye. ilungiswe yimveliso ye-NVM), akukho ndlela yokukhetha inqanaba le-RAID elifunekayo okanye ukwandisa i-SSD quota, ngelixa ngokwenene sibeke abathengi be-2 kuphela kwiiyunithi ze-3. Ngokubanzi, kwakukho iintsilelo, isisombululo sasingekho kumntu wonke.
Mhlawumbi ndiya kuvula amehlo abanye, kodwa eNetherlands, amaziko amaninzi edatha awanalo i-hardware yabo, ngenxa yeerhafu ezinkulu ezivela xa zithenga kwaye zithengwa. Yonke into iphantsi kwexesha elide (inkontileka yeminyaka elishumi okanye ngaphezulu) yokuqeshisa kumenzi (Dell, HP, Supermicro). Nto leyo inciphisa kakhulu. Emva kwayo yonke loo nto, ukuze siqinisekise ixabiso eliphantsi kakhulu, kuye kwafuneka sishiye yonke i-zoo yoqwalaselo kwaye sisayine, elona qonga lisebenzayo kuye wonke umntu. Kwaye sasebenzisa ubuchule beqonga ukuya phezulu, ukuhlangabezana neemfuno ezingaphezu kwe-95% yababhalisi.
Kodwa abazange bakwazi ukuyicombulula ngokupheleleyo le ngxaki. Kwaye okwangoku "ngaphezu kwe-95%" yabathengi abachasene nokuphuculwa. Ngokuqinisekileyo, akunzima ukufaka olunye ulungelelwaniso, kodwa umbuzo wonke lixabiso. Sikhuphisana njani neminikelo enkulu yexabiso eliphantsi ngelixa sisanikezela ngekhwalithi ephezulu kunye ne-hardware ephezulu kwixabiso elifanayo okanye eliphantsi?
NgoJanuwari walo nyaka, savula iofisi yethu yommeli waseYurophu SIA UA-Hosting eLatvia ngenxa yale njongo. Oku akwanelanga nje ukwenza lula ukusebenza nathi kubabhalisi beshishini, kodwa kwenze ukuba kube nokwenzeka ukuqalisa ukubuyisela i-VAT kwizinto ezithengiweyo, okuthe kwalithoba kakhulu ixabiso. Emva kwexesha elithile, ngokuqinisekileyo siya kwabelana ngamava ethu. Kuya kubakho inqaku elineenkcukacha ezahlukeneyo malunga nokuba kulula kangakanani ukubhalisa ngoku eYurophu, endaweni yeBelize, kwaye kunzima kangakanani ukuvula i-akhawunti yebhanki kwilizwe lokubhalisa, nokuba unayo yonke imibhalo efunekayo kule nto. Akukho nanye kwiinkampani ezikuncedayo namhlanje eziza kukunika i-akhawunti yebhanki eLatvia kwinkampani yaseLatvia, wonke umntu uya kunika iSwitzerland kwaye uya kufuna i-euro ye-4000 nje ngoncedo lokuvula i-akhawunti, engayi kuba lula ngakumbi kamva ukuba wamkela i-PayPal ngqo ( iya kukhokelela kwiikomishini ezongezelelweyo kwaye iimali ziya kuthi ekugqibeleni zibe ngamashumi amawaka eeuro ngonyaka, kuxhomekeke kwingeniso yakho, ekubeni iikhomishini ezongezelelweyo zisetyenziswa ukuba i-akhawunti yakho ayikho kwilizwe lokubhalisa).
Kodwa namhlanje makhe siqhubeke malunga nehardware. Sicinge ixesha elide kwaye sinzima malunga nesisombululo se-1U esinokusinika. Luhlobo luni lomncedisi olunokwanelisa ngokupheleleyo iimfuno ze-5% yabathengi kunye nokwandisa kakhulu amandla akhoyo ngoku?
Sachitha iinyanga eziliqela sicinga, sikhetha yaye sivavanya. Sithelekise isilathisi esineendleko ezifanelekileyo kuwe. Ngokuqinisekileyo, akukho nto ingcono kune-Dell R730xd okwangoku :) Ngaphandle koko, asizange siqhubeke sinikezela ngezi zisombululo, kwaye ngendlela, saqala ukwenza oku kunye neeprosesa ezihlaziyiweyo, eziyiTetradeca Core, kungekhona iDodeca, oko kukuthi, ii-cores ezili-14 ezipheleleyo kwiprosesa nganye, i-28 ithathela ingqalelo i-hypertrading, kwaye kunye ne-frequencies ye-2.6 GHz, endaweni ye-2.2, kwaye bade bagqiba ekubeni banciphise ixabiso, bebeka izixhobo ngaxeshanye. , kodwa ngokusisiseko inika kuphela i-64GB DDR4 RAM, kwaye hayi i-128, kuba ayinguye wonke umntu ofuna loo nto ingako:
I-Dell R730xd - 2x E5-2697v3 2.6GHz 14C 64GB DDR4 4x960GB SSD 1Gbps 100TB - $199 / ngenyanga, nangona ukuba uhlawula iminyaka emi-2, ngenyanga kwaye ukuba uhlawula unyaka kuya kuba yindleko, nangona kunjalo, jonga ukuba kuhle kangakanani. :
Sisebenzisa i-Fortigate ukucwangcisa ufikelelo olukhuselekileyo kumxhasi ngamnye kwiseva yerenti ye-iDrac. Ndiyabulela kwi-Forticlient, unokufikelela kwinethiwekhi yangaphakathi, kwaye yonke i-traffic yakho ayiyi kudlula kwi-tunnel ye-VPN, kuphela i-traffic kwinethiwekhi yangaphakathi iya kudlula kuyo, ekulungele kakhulu, ngokungafani ne-VPN eqhelekileyo. Sidibanisa zonke iiseva kwii-PDU ezimbini ezizimeleyo (asitsiki kwiisokethi):
Umtshini ngamnye we-rack uxhunywe yi-2x10G i-fiber optic links kwi-switch switches, i-traffic esuka apho iqhutywe ngama-cores eedatha ezimbini ezizimeleyo. Okokuthi, asizange sinike kuphela ixabiso le-2 ngamaxesha aphantsi kwexabiso lemarike, kodwa sinike inethiwekhi ye-premium ngexabiso elifanayo. I-intanethi ye-intanethi ihanjiswa ngababoneleli bezothutho be-Tier I njenge-GTT kunye ne-NTT, ngoko uxhulumaniso ngaphandle kokubhuka kubiza malunga ne-7000 ye-euro ye-10G kwiziko ledatha ngokuthe ngqo, kodwa sibonelela nge-2N ββngexabiso elingaphezu kwe-2 amaxesha aphantsi, igigabit nganye eyongezelelweyo i-$ 450. Ewe, ewe, eli xabiso libandakanya into yokuba ayinguye wonke umxhasi oya kusebenzisa umda wabo ngokupheleleyo, yingakho "sibeka emngciphekweni" ngokunika ixabiso elinjalo. Izibalo - iminyaka emininzi yamava okwenene. Iiseva ze-500 ezinoxhumo lwe-gigabit kunye nomda we-traffic we-100 TB zisebenzisa i-avareji malunga ne-20 Gbit / s (kwaye kungekhona i-160-200 Gbit / s, njengoko umntu enokucinga), ezi ziyidatha yangempela. Ewe kunjalo, ababhalisile abaqale basebenzise kakhulu xa beodola i-Unmetered abathathelwa ngqalelo. Kungenxa yokuba ayinguye wonke umntu osebenzisa i-TB yakhe eyi-100, yiyo loo nto singoyiki ukuthengisa i-traffic yabantu ngamaxabiso aphantsi kunaleyo apho umboneleli wezothutho athengisa khona unxibelelwano.
Phakathi kwezinye izinto, sibonelela ababhalisi bethu nge-1G okanye i-10G LAN, kunye needilesi ze-IP ezivela kwi-RU GEO okanye i-NL amanethiwekhi kunye nokukwazi ukusebenzisa i-firewalls kunye nokutshintsha kwangasese. Nangona kunjalo, nangona sinikezela ngeeseva ngexabiso elingaphantsi kwamaxesha ama-2 ngaphantsi kwexabiso lemarike, kwaye sithathela ingqalelo inethiwekhi ye-premium - amaxesha angama-3-4 ngaphantsi kwexabiso lemarike, kusekho inxalenye echazwe ngasentla yabathengi. abangakwaziyo ukufikelela kumncedisi onjalo, kodwa i-VPS (isahlulo sesithathu somncedisi wenyama) ayanelisi ngenxa yezizathu ezahlukeneyo.
Sichithe ixesha elide sikhetha olona lungelelwaniso lungcono, kuba besisafuna ukunika βeyona nto intshaβ, kodwa kwangaxeshanye ineendleko ezifanelekileyo, kwaye safikelela kwisigqibo sokuba singathanda ukunika i-128GB DDR3 RAM kune-64GB DDR4. Kutheni?
- ukusebenza ngexesha elifanayo le-2400 MHz, i-DDR3 kunye ne-DDR4 imemori ye-memory stick ibonisa iziphumo ezifaniswayo;
I-latency ye-DDR4 kule meko yi-15 nanoseconds, kunye ne-DDR3 - i-nanoseconds eyi-11, oko kukuthi, kwiifrikhwensi ezinjalo, imemori ye-DDR3 nayo "ikhawuleza" ngokwemiqathango ye-latency;
-Naziphi na izibonelelo zeDDR4 ziqala ukubonakala kuphela kwiifrikhwensi ezingaphezulu kwe-3000 MHz, engeyomfuneko kuye wonke umsebenzisi; ngamanye amaxesha ukubambezeleka kubaluleke ngakumbi.
Umahluko phakathi kwe-DDR3-2133 kunye ne-DDR4-2133 ijika ibe yinto engabalulekanga kwinani lezicelo, kubandakanya iimeko zokuguqulwa kwevidiyo. I-DDR3 ikhawuleza ngaphezu kwesiqingatha samatyala.
Kwaye ekubeni injongo yethu yayikukunikezela ngexabiso elincinci leqonga, kodwa kwangaxeshanye ixabiso elifanelekileyo, sagqiba ekubeni sizame ukubonelela ngolu hlobo lulandelayo eNetherlands luqala kwi-99 yeedola / ngenyanga (ixabiso leVPS):
Dell R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 2x960GB SSD 1Gbps 100TB - order
Okokuqala, sifuna ukufunda imfuno, sikubuze ukuba senze impazamo? Sele sikufakele amaqonga amaninzi anje kwi-rack yeeseva ze-1U (kwaye sisenomgangatho womgangatho endaweni ukuze singaxubi amaqonga ahlukeneyo kwindawo enye ngokujonga ukusetyenziswa ngokufanelekileyo kwezixhobo zenethiwekhi namandla) kwaye sigqiba ukwakhiwa kwayo. :
Uqwalaselo luxhasa ukuya kuthi ga kwi-8 SSD drives ukuya kuthi ga kwi-2 PCIe NVMe (ukuba inethiwekhi ye-10G iyafuneka, ngoko ke idrayivu enye, kuba ikhadi le-10G lesibini liya kuhlala kwelinye lamazibuko). Sagqiba ekubeni singanikezeli amandla adlayo kunye nee-HDD ezicothayo ngolu lungelelwaniso, kodwa ukubonelela ezimbini ze-Samsung 960GB (MZ7LH960HAJR) ngexabiso elihle. Xa uhlawula umncedisi ixesha elingaphezu konyaka, iidrive ezongezelelweyo zi-2 amaxesha angabizi, kuphela + $ 25 / ngenyanga nge-drive. Ewe, nge-249 yeedola/ngenyanga ungafumana phantse i-8 TB SSD quota kunye ne-Dell elungileyo R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 8x960GB SSD 1Gbps 100TB iseva.
I-1 Γ 3.2TB eyongezelelweyo ye-PCI-E Samsung PM1725b SSD drive iya kuba yindleko β + $ 250 / ngenyanga (kufuneka ubuncinane sifumane imali kwinto engaphezu kwe-5.7 iminyaka), kodwa izaphulelo zinokwenzeka kwirenti yexesha elide. Kutheni sifaka kwaye sinikeze kuphela iidrives ezinjalo, kwaye hayi i-NVMe eshushu-swap-swap M2? Ezi drives zisengcono, i-latency iphantsi ngamaxesha amaninzi ngenxa yoqhagamshelwano lwe-PCI-E. Ezi ziidrive ezisetyenziswa, yithi, iibhanki okanye abathengi abasebenzisa uhlobo oluthile lokucubungula. Ii-M2s zisebenza kancinci kakhulu kule misebenzi. Kwaye nangona kukho i-1.6 TB kunye ne-6.4 TB drives kwimarike, isizathu sokungazisebenzisi silula. Kwimeko ye-TB ye-1.6, umthamo uncinci kakhulu, i-PCI-E slots ingasetyenziselwa ngokukhawuleza, kwaye kwimeko ye-6.4 TB, inkqubo yokubuyisela iya kuthatha ixesha elide, ngoko ke i-3.2 TB yayikhethwe ngokufanelekileyo njenge "golide". thethaβ.
Sikwanika ingqwalasela ebalulekileyo kwinto efana nentambo. Emva koko, ubuhle bokubeka ikhebula bunquma indlela umntla oya kupholiswa ngayo kunye nokusetyenziswa kwamandla okwenzekayo ngenxa yale nkqubo. Ngokuhlanganisa iintambo ngamaqela, sinciphisa indawo "yokuvimba" kwindlela yomoya oshushu kwaye ichithwa ngokufanelekileyo kwii-racks, ekubeni i-turbulence ephazamisa ukutshatyalaliswa kobushushu obusebenzayo iyancitshiswa.
Ngokubanzi ndiyakholelwa ukuba ubumbeko luphumelele. Nangona kunjalo, sikulungele ukumamela ukugxekwa kwesi siphakamiso esivela kubafundi bakaHabr, emva koko, rhoqo, ngokuvakalisa izimvo, usikhokele kwindlela elungileyo, kwaye sinomdla wokukunika ezona zisombululo zisebenzayo kwixesha elizayo. Enkosi kakhulu kwangaphambili ngale nto! Unikezelo lulinganiselwe kubungakanani kwaye ngoku sineeseva ezili-16 eNetherlands. Andibandakanyi ukuba kwixesha elizayo, ixabiso lee-odolo ezintsha linokuba phezulu, kodwa ngoku unethuba elihle lokucwangcisa iseva ngexabiso eliphantsi kakhulu (enyanisweni, ngexabiso le-colocation, ngokujonga zonke iingenelo. ichaziwe).
Kuyacaca ukuba kubasebenzisi beHabr kukho ibhonasi emnandi - +1 inyanga simahla xa uhlawula iDell R420 kangangeenyanga ezi-3 okanye ngaphezulu. (ukufumana ibhonasi, vele ushiye inombolo yakho yeodolo apha kwizimvo kwaye ube ngumsebenzisi weHabr obhalisiweyo). Ngaloo ndlela, unethuba lokusebenza kwiinyanga zokuqala ze-4 ngexabiso le-$ 119, uvavanya umgangatho, uze utshintshele kumjikelezo wentlawulo yeminyaka emibini, uhlawulela inkonzo ye-2 iminyaka kunye nokufumana ixabiso elikhethekileyo le-$ 99 / ngenyanga. ngomncedisi ngamnye!
Sisebenza ngokomzimba abantu namaqumrhu asemthethweni abantu abavela kwiRussian Federation, Ukraine kunye nehlabathi liphela phantsi kwesivumelwano; izivumelwano zigqitywa phakathi kwethu (SIA UA-Hosting, Latvia) kunye nenkampani yakho. Qhagamshelana nathi, siya kukuvuyela ukusebenzisana!
