Papita zaka ziwiri kuchokera pamene tinayamba kupereka nsanja (Nthawi 2 zotsika kuposa kuchuluka kwa msika), chifukwa pakugula, ngakhale pano, m'badwo waposachedwa wa E5-2650 v4 processors akulengezedwa kutha kwa moyo ndi wopanga, amawononga 8500 mayuro + 21% VAT = 10285 mayuro (nthawi yobwezera 5.7 zaka, ngati tiganizira za mtengo wa colocation ndi magalimoto ndipo osaganizira mtengo wa ndalama zothandizira):
Takhazikitsa bwino mayankho amagulu ambiri pamapulatifomu awa kwa olembetsa mabizinesi athu, komanso ogwiritsa ntchito payekhapayekha. Tidapanga ndikukhazikitsa bwino chinthu china - ma seva omwe ali ndi zosungirako zodzipereka, zomwe zidapangitsa kuti zitheke kusintha mzere woyamba wa ma seva odzipatulira ndikupereka ma seva a VPS ndi zinthu za 10-40GB DDR4 RAM, 6-24 E5-2650 v4 cores, ndi chofunika kwambiri - 1- 4 odzipereka kwathunthu 4TB HDD kapena 240-480GB SSD ma drive. Tinafotokoza mwatsatanetsatane ubwino ndi kuipa kwa mankhwalawa apa: (Zosankha ndi RAID1 ndi RAID10 zilipo).
Ndipo zonse zikuwoneka kuti zili bwino, tidakwaniritsa dongosolo lazogulitsa, kugulitsa kuposa momwe tidakonzera, ogwiritsa ntchito masauzande ambiri adagula mayankho athu, chifukwa chomwe tatsala pang'ono kuchotseratu ma seva akale ndi E3-1230 ndi E5620 processors, omwe adalamulidwa. ndi omwe adalembetsa omwe sanathe kulipira Dell R730xd, ngakhale tidapanga kuti ikhale yotsika mtengo momwe tingathere. Kupatula apo, tsopano akanatha, titi, VPS (KVM) iyi - E5-2650 v4 (24 Cores) 40GB DDR4 yokhala ndi 4x240GB RAID10 SSD kapena 4x4TB RAID10 HDD 1Gbps 40TB pamtengo wa E3-1230 womwewo. Chifukwa chiyani sikuli bwino m'malo mwa E3-1230 yakale yokhala ndi ma disks omwewo? Kapena adasankhanso njira yokhala ndi zida zochepera 2 (pamene zinthu zambiri sizinkafunikira), ndikusunga ndalama zoposa theka la bajeti. Zotsatira zake, sitinangochepetsa mtengo wamagetsi ndi kukonza, chifukwa zida zatsopano zimalephera nthawi zambiri ndipo sizilephera, zimakhala zogwira mtima kwambiri, olembetsa ambiri amatha kuyikidwa pamayunitsi ochepera, koma chofunikira kwambiri, tidawonjezera kuchuluka kwa kasitomala. kukhutitsidwa ndi utumiki wathu.
Komabe, sitinathe kukwaniritsa zosoΕ΅a za kagulu kakangβono ka olembetsa. Kupatula apo, zinali zosatheka kupanga malo owoneka bwino m'malo omwe analipo kale (ngakhale zidule zina zidagwiritsidwa ntchito ngati ma Dockers ndi zinthu zina) + RAM "kokha" mpaka 40GB (vutoli linali pang'ono). kukonzedwa ndi chinthu cha NVM), palibe njira yoti musankhe mulingo wa RAID womwe mukufuna kapena kuwonjezera gawo la SSD, pomwe tidayika makasitomala atatu okha pamayunitsi a 2. Mwambiri, panali zophophonya, yankho silinali la aliyense.
Mwina nditsegula maso a ena, koma ku Netherlands, malo ambiri akuluakulu a deta alibe zipangizo zawo, chifukwa cha misonkho yaikulu yomwe imabwera pamene muli ndi kugula. Chilichonse chili pansi pa nthawi yayitali (mgwirizano wazaka khumi kapena kuposerapo) kubwereketsa kuchokera kwa wopanga (Dell, HP, Supermicro). Zomwe zimalepheretsa kwambiri. Kupatula apo, kuti titsimikizire kuti mtengo wake ndi wotsika kwambiri, tinayenera kusiya zoo zonse ndikusaina imodzi, nsanja yothandiza kwambiri kwa aliyense. Ndipo tidagwiritsa ntchito luso la nsanja mpaka pamlingo waukulu, kukwaniritsa zosowa za olembetsa oposa 95%.
Koma sanathe kuthetsa vutolo. Ndipo makasitomala apano "oposa 95%" samatsutsana ndi kusintha. Inde, sikovuta kukhazikitsa kasinthidwe kwina, koma funso lonse ndi mtengo. Kodi timapikisana bwanji ndi zopereka zazikulu zotsika mtengo pomwe tikuperekabe zida zapamwamba komanso zotsika mtengo pamtengo womwewo kapena wotsika?
Mu Januware chaka chino, tidatsegula ofesi yathu yoyimira ku Europe SIA UA-Hosting ku Latvia pachifukwa ichi. Izi sizinangowonjezera mwayi wogwirira ntchito nafe kwa olembetsa mabizinesi, komanso zidapangitsa kuti zitheke kubweza VAT pazogula, zomwe zidachepetsanso kwambiri mtengo. Patapita nthawi, tidzagawana zomwe takumana nazo. Padzakhala mwatsatanetsatane nkhani zosiyana za momwe kulili kosavuta kulembetsa tsopano ku Ulaya, m'malo mwa Belize, ndi momwe zimakhalira zovuta kutsegula akaunti yakubanki m'dziko lolembetsa, ngakhale mutakhala ndi zikalata zonse zofunika pa izi. Palibe makampani omwe akukuthandizani lero omwe angakupatseni akaunti yakubanki ku Latvia kwa kampani yaku Latvia, aliyense adzapereka Switzerland ndipo adzafuna ma euro 4000 kuti athandizidwe potsegula akaunti, zomwe sizingakhale zosavuta pambuyo pake ngati muvomereza PayPal mwachindunji ( zidzabweretsa ma komisheni owonjezera ndipo ndalamazo zidzafika ma euro masauzande ambiri pachaka, kutengera zomwe mwapeza, chifukwa ma komiti owonjezera amaperekedwa ngati akaunti yanu sikhala m'dziko lolembetsa).
Koma lero tiyeni tipitilize za hardware. Tinaganiza mozama komanso mozama za yankho la 1U lomwe tingapereke. Ndi seva yamtundu wanji yomwe ingakwaniritse zosowa za 5% yamakasitomala ndikukulitsa kwambiri kuthekera kwa omwe alipo?
Tinatha miyezi ingapo kuganizira, kusankha, ndi kusanthula. Tidafanizira chizindikiro chotsika mtengo kwa inu. Inde, sipangakhale china chabwino kuposa Dell R730xd komabe :) Kupanda kutero, sitikanapitiriza kupereka mayankhowa, ndipo mwa njira, tinayamba kuchita izi ndi mapurosesa osinthidwa, omwe ali Tetradeca Core, osati Dodeca, ndiko kuti, ma 14 amtundu wathunthu mu purosesa iliyonse, 28 kutengera hypertrading, komanso ma frequency a 2.6 GHz, m'malo mwa 2.2, ndipo adaganiza zochepetsera mtengo, ndikuyika zida nthawi yomweyo. , koma kwenikweni amapereka 64GB DDR4 RAM yokha, osati 128, chifukwa si aliyense amene amafunikira zambiri:
Dell R730xd - 2x E5-2697v3 2.6GHz 14C 64GB DDR4 4x960GB SSD 1Gbps 100TB - $199 / mwezi, ngakhale mutalipira zaka 2, pamwezi ndipo ngati mutalipira chaka chidzakhala chokwera mtengo, komabe, yang'anani kukongola kwake. :
Timagwiritsa ntchito Fortigate kukonza njira zotetezeka za kasitomala aliyense ku seva yobwereketsa ya iDrac. Chifukwa cha Forticlient, muli ndi mwayi wopita ku netiweki yamkati, ndipo magalimoto anu onse sadzadutsa mumsewu wa VPN, magalimoto okhawo opita ku netiweki yamkati adzadutsamo, zomwe ndi zabwino kwambiri, mosiyana ndi VPN wamba. Timalumikiza ma seva onse ku ma PDU awiri odziyimira pawokha (sitimadumpha pamapaketi):
Kusintha kulikonse kumalumikizidwa ndi 2x10G fiber optic maulalo ku zosinthira zogawa, magalimoto omwe amayendetsedwa ndi ma cores awiri odziyimira pawokha. Ndiko kuti, sitinangopereka mtengo 2 nthawi zochepa kuposa mtengo wamsika, komanso tinapereka maukonde apamwamba pamtengo womwewo. Magalimoto a pa intaneti amaperekedwa ndi opereka maulendo a Tier I monga GTT ndi NTT, kotero kugwirizanitsa popanda kusungirako kumawononga pafupifupi 7000 euro kwa 10G mu data center mwachindunji, koma timapereka 2N pamtengo woposa 2 nthawi zotsika mtengo, gigabit iliyonse yowonjezera ndi $ 450 . Inde, ndithudi, mtengo uwu umaphatikizapo mfundo yakuti si kasitomala aliyense amene angawononge malire awo, ndichifukwa chake "tinaika pachiwopsezo" popereka mtengo wotere. Ziwerengero - zaka zambiri zenizeni zenizeni. Ma seva a 500 okhala ndi gigabit kugwirizana ndi malire a magalimoto a 100 TB amadya pafupifupi 20 Gbit / s (osati 160-200 Gbit / s, monga momwe angaganizire), izi ndi deta yeniyeni. Zachidziwikire, olembetsa omwe poyamba amadya kwambiri akamayitanitsa Unmetered samaganiziridwa. Kungoti si aliyense amene amadya 100 TB yawo, chifukwa chake sitichita mantha kugulitsa magalimoto a anthu pamitengo yotsika kuposa yomwe wogulitsa amagulitsa kulumikizidwa.
Mwa zina, timapereka olembetsa athu 1G kapena 10G LAN, komanso ma adilesi a IP ochokera ku ma RU GEO kapena ma NL network komanso kuthekera kogwiritsa ntchito zida zozimitsa moto ndi zosintha zapadera. Komabe, ngakhale tidapereka ma seva pamtengo wochepera 2 kuposa mtengo wamsika, ndikuganizira maukonde oyambira - 3-4 nthawi zotsika kuposa mtengo wamsika, pali gawo lomwe lafotokozedwa pamwambapa la makasitomala. omwe sangathe kulipira seva yotere, koma VPS (gawo limodzi mwa magawo atatu a seva yakuthupi) siili yokhutiritsa pazifukwa zosiyanasiyana.
Tidakhala nthawi yayitali ndikusankha masinthidwe abwino kwambiri, popeza tinkafunabe kupereka "zatsopano", koma nthawi yomweyo zotsika mtengo, ndipo tidafika pomaliza kuti titha kupereka 128GB DDR3 RAM kuposa 64GB DDR4. Chifukwa chiyani?
- kugwira ntchito pafupipafupi 2400 MHz, DDR3 ndi DDR4 memory sticks kusonyeza zotsatira zofanana;
- latency ya DDR4 pankhaniyi ndi 15 nanoseconds, ndi DDR3 - 11 nanoseconds, ndiye kuti, pama frequency otero, kukumbukira kwa DDR3 kumakhalanso "mwachangu" pankhani ya latency;
- Ubwino uliwonse wa DDR4 umayamba kuwonekera pamafuriji opitilira 3000 MHz, zomwe sizofunikira kwa aliyense wogwiritsa ntchito; nthawi zina latency ndiyofunikira kwambiri.
Kusiyana pakati pa DDR3-2133 ndi DDR4-2133 kumakhala kocheperako pamapulogalamu angapo, kuphatikiza milandu yosinthira makanema. DDR3 imathamanga kwambiri kuposa theka la milandu.
Ndipo popeza cholinga chathu chinali kupereka nsanja yotsika mtengo, koma panthawi imodzimodziyo yotsika mtengo, tinaganiza zoyesera kupereka njira yotsatirayi ku Netherlands kuyambira $ 99 / mwezi (mtengo wa VPS):
Dell R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 2x960GB SSD 1Gbps 100TB - dongosolo
Choyamba, tikufuna kuphunzira zomwe tikufuna, ndikufunseni ngati talakwitsa? Takuikirani kale nsanja zingapo zotere muchoyikapo cha ma seva a 1U (ndipo tidayikabe zokhazikika kuti tisakanize mapulatifomu osiyanasiyana pachiwongolero chimodzi potengera kugwiritsa ntchito moyenera zida za netiweki ndi mphamvu) ndipo tikumaliza kumanga. :
Zosintha zimathandizira mpaka ma drive 8 a SSD mpaka 2 PCIe NVMe (ngati netiweki ya 10G ikufunika, ndiye kuti galimoto imodzi, popeza khadi yapawiri ya 10G itenga limodzi mwamadoko). Tidasankha kuti tisapereke ma HDD owononga mphamvu komanso pang'onopang'ono ndi kasinthidwe kameneka, koma kuti tipereke ma Samsung 960GB (MZ7LH960HAJR) awiri pamtengo wabwino. Polipira seva kwa nthawi yoposa chaka, ma drive owonjezera ndi otsika mtengo nthawi 2, okha + $ 25 / mwezi pagalimoto. Inde, pa $249/mwezi mutha kupeza pafupifupi gawo la 8 TB SSD ndi seva yabwino ya Dell R420 2x E5-2430 2.2Ghz 6C 128GB DDR3 8x960GB SSD 1Gbps 100TB.
1 Γ 3.2TB PCI-E Samsung PM1725b SSD galimoto adzakhala okwera mtengo β + $250 / mwezi (tiyenera osachepera kupeza ndalama chinachake kwa zaka zoposa 5.7), koma kuchotsera n'zotheka kubwereka kwa nthawi yaitali. Chifukwa chiyani timayika ndikupereka ma drive okhawo, osati NVMe hot-swap M2? Ma drive awa akadali bwino, latency imakhala yotsika nthawi zambiri chifukwa cha kulumikizana kwa PCI-E. Awa ndi ma drive omwe amagwiritsidwa ntchito, mwachitsanzo, mabanki kapena makasitomala omwe amagwiritsa ntchito mtundu wina wa kukonza. Ma M2 sagwira bwino ntchito izi. Ndipo ngakhale pali 1.6 TB ndi 6.4 TB zoyendetsa pamsika, chifukwa chosagwiritsa ntchito ndizosavuta. Pankhani ya 1.6 TB, voliyumuyo ndi yaying'ono kwambiri, ma PCI-E amatha kugwiritsidwa ntchito mwachangu, ndipo ngati 6.4 TB, kuchira kumatenga nthawi yayitali, kotero 3.2 TB idasankhidwa moyenerera ngati "golide". zikomoβ.
Timatcheranso chidwi kwambiri ku chinthu monga chingwe. Kupatula apo, kukongola kwa kuyika kwa chingwe kumatsimikizira momwe kumpoto kudzazirala komanso kugwiritsa ntchito mphamvu zomwe zimachitika chifukwa cha njirayi. Posonkhanitsa zingwe m'magulu, timachepetsa malo "otsekereza" panjira ya mpweya wotentha ndipo amachotsedwa bwino pazitsulo, chifukwa chipwirikiti chomwe chimasokoneza kutentha kwabwino kumachepetsedwa.
Ponseponse ndikukhulupirira kuti kasinthidwe kadapambana. Komabe, ndife okonzeka kumvera kutsutsidwa pamalingaliro awa kuchokera kwa owerenga a Habr, pambuyo pa zonse, nthawi zambiri, popereka malingaliro, mudatitsogolera panjira yoyenera, ndipo tikufuna kukupatsani mayankho ogwira mtima kwambiri mtsogolo. Zikomo kwambiri pasadakhale chifukwa cha izi! Zoperekazo ndizochepa ndipo tili ndi ma seva 16 ku Netherlands. Sindikupatula kuti mtsogolomo, mtengo wamaoda atsopano ukhoza kukhala wokwezeka, koma tsopano muli ndi mwayi wabwino kwambiri wopanga seva pamtengo wotsika kwambiri (makamaka, pamtengo wa colocation, poganizira zabwino zonse. anafotokoza).
Sizikunena kuti kwa ogwiritsa ntchito a Habr pali bonasi yabwino - +1 mwezi waulere mukalipira Dell R420 kwa miyezi itatu kapena kupitilira apo. (kuti mulandire bonasi, ingosiyani nambala yanu yoyitanitsa apa mu ndemanga ndikukhala wolembetsa wa Habr). Choncho, muli ndi mwayi wogwira ntchito kwa miyezi 4 pamtengo wa $ 119, fufuzani khalidwe, ndiyeno sinthani ku malipiro a zaka ziwiri, kulipira ntchito kwa zaka 2 ndikulandira mtengo wapadera wa $ 99 / mwezi. pa seva!
Timagwira ntchito ndi thupi anthu ndi mabungwe azamalamulo anthu ochokera ku Russian Federation, Ukraine ndi dziko lonse lapansi pansi pa mgwirizano; mapangano amakwaniritsidwa pakati pathu (SIA UA-Hosting, Latvia) ndi kampani yanu. Lumikizanani nafe, tidzakhala okondwa kugwirizana!
