Imiphumela yokuhlolwa ibonisa izinzuzo eziphawulekayo zokusebenza kwezinkundla ze-Dell R730xd lapho kusetshenziswa ukugcinwa kwenqolobane ye-SanDisk DAS uma kuqhathaniswa ne-HPE SmartCache, nokusekelwa kwe-NVMe PCIe SSD kunikeza izinzuzo ezinkulu nakakhulu. Ezilinganisweni ze-OLTP, i-R730xd ibonise i-IOPS ephindwe izikhathi ezi-3 ngenxa yokusetshenziswa kwe-SanDisk DAS Cache nama-SAS SSD futhi izikhathi ezingu-6 ngaphezulu ngenxa yokusetshenziswa kwe-SanDisk DAS Cache + NVMe PCIe SSDs uma kuqhathaniswa ne-HPE's SmartCache. Ukusetshenziswa okuphezulu kwe-CPU nge-SanDisk DAS Cache, kanye nokusetshenziswa kwe-CPU ephakeme nakakhulu nge-SanDisk DAS Cache + NVMe PCIe SSDs, kumane kuwumphumela wokubala okuphezulu kakhulu kwe-IOPS. futhi, ngokuphambene nalokho, kukhombisa ukusetshenziswa okungcono kakhulu kwezinsiza zokucubungula.
Ngakho-ke, uma ku-HP ngokusetshenziswa okungu-6% umphumela we-IOPS uyizinkulungwane ezingama-41, okungukuthi, i-1% yezinsiza zokucubungula isetshenziswa nge-IOPS eyinkulungwane eyi-0,15, ngakho-ke esimweni se-Dell R730xd sinokusetshenziswa okungu-16% ku-264 ayizinkulungwane, okuyinto inikeza inkomba esebenza kahle kakhulu - 0,06% wezinsiza zokucubungula ngo-1000 IOPS ngayinye.
Okusho ukuthi, ngokuya ngokusetshenziswa kweprosesa, iDell ibuye ibe ngcono (izikhathi ezingama-2,5), yize inamanani wokusetshenziswa kweprosesa aphezulu ngo-%, kodwa, njengoba sikwazile ukuqinisekisa, lokhu kungumphumela wokucubungula. inani elikhulu kakhulu lemisebenzi, kanjalo nokukhiqiza okungcono.
Ngakho-ke, isiteji se-Dell R730xd sibonakala sisebenza kahle kakhulu kune-HP ProLiant DL380 (izikhathi eziningi), kokubili ngokusebenza nokusebenza kahle kwezindleko.
Imiphumela yokuhlolwa kwe-Geekbanch 3 i-Dell R730xd ene-E5-2640 v4 processor noma kungani imiyalelo yokucubungula kanye nenqolobane yesilawuli kubalulekile
Njengoba sibona ngenhla, singathola imiphumela ephezulu kuphela uma izingxenye ezintathu - amandla ekhompiyutha, isitoreji kanye nenethiwekhi - zilinganiselwe, njengoba kuncishiswa izithiyo ezingaba khona ohlelweni olungalinganiseli.
Kepha futhi okubaluleke kakhulu ukwesekwa komprosesa wesikhulumi semiyalo eminingi nokusebenza kwayo kahle. Sengike ngasho ngenhla ukuthi umehluko obonakala ungelutho ezizukulwaneni ungadlala indima ebalulekile kwezinye izimo. Ngakho-ke, ngokwemiphumela yokuhlolwa okuzimele, i-E5-2650 v4 esiyinikezayo isebenza kahle ngo-70% esimweni sokubethela (imiyalo ye-AES) kune-E5-2650 v3.
Kuthiwani-ke ngezixazululo "ezihlwabusayo" ezivela kubancintisana nezindleko eziphansi, kodwa hhayi ingxenye ye-premium? Kungani izixazululo zethu zingcono? Kungani izisombululo zethu ziyi-premium? Impendulo ilula - amaseva ethu ayekhona futhi abhalansile. Ngisho noma ngaphambilini bezinamafrikhwensi aphansi noma amanani amancane enkumbulo, bezihlale zibhalansiswa ngokwamapharamitha amathathu achazwe ngenhla. Kubandakanya isikhungo sedatha esithembekile esinezitifiketi ezidingwa ingxenye yebhizinisi kanye neziteshi ezinhle kakhulu zokuxhumana zangaphandle ezinikeza ukubambezeleka okuncane okuvela e-Netherlands, kokubili kulo lonke elaseYurophu, naseRussia nase-Ukraine, ngisho
Kodwa manje senze isipho sokuncintisana ngokwemibandela yalezi zinkomba, ezindaweni ezingu-10 ngesikhathi esisodwa, eyodwa eNetherlands nezindawo ezingu-9 e-USA, kodwa masingakhulumi ngathi, ake sibheke ukuhlolwa. Ngeshwa, lokhu kuhlolwa okwamanje kutholakala kuphela kunguqulo ye-E5-2640 v4, ene-10, hhayi ama-cores angu-12, yesikhulumi sethu.
Yiqiniso, akuyona inhloso kakhulu, njengoba ingacabangi zonke izinzuzo zesikhulumi, i-cache efanayo ye-SanDisk DAS esikhulume ngayo, izinkomba zokusebenza zangempela zingaba ngcono kakhulu kunezokwenziwa endaweni ethile. icala, kakhulu! Kodwa kusengenzeka ukuthola ukuqonda okuthile.
Ake sinake iziyalezo eziningi. Okubonisa kakhulu kungase kube i-AES eshiwo kakade, cishe kumafrikhwensi afanayo umehluko phakathi kwamanani we-1st core ungaba izikhathi ezingu-1000 kuye ngokuthi iphrosesa, imiyalelo esele eyaqhathaniswa yabonisa umehluko wamanani kusuka izikhathi eziningana kuya kweziyi-100.
Ungakwazi ngokwakho futhi wenze isiqhathaniso, kodwa ungakhohlwa ukuthi lokhu kuhlolwa akubonisi ngokuphelele, ngoba akunaki i-hardware iyonke, kodwa ikakhulukazi kubonisa iphrosesa.
Noma kunjalo, ngithemba ukuthi le miphumela ingaba usizo kuwe lapho uhlaziya ukusebenza kwesixazululo esithile.
Ukusebenzisa amaseva e-Dell R730xd njenge-Bare Metal, kungcono nje!
Amanye amakhasimende ethu anqume ukuyeka ukusetshenziswa kwezixazululo zefu ze-VMware ukuze avune izixazululo ze-Bare Metal (amaseva ensimbi) futhi inkundla ye-Dell R730xd yabasiza kakhulu kulokhu. Futhi lapha asikhulumi kuphela ngamafu omphakathi, kodwa futhi nangasese.
Kungani abantu benza izinqumo ezinjalo ngokwandayo? Mayelana namafu omphakathi, yonke into isobala kakhulu. Mina ngokwami ββngibheka amafu omphakathi njengokumaketha okukhulu, uma okuthile kuwa lapho (futhi wonke amafu awela ngokushesha noma kamuva), awela lapho isikhathi eside. Isibonelo i-Amazon efanayo eyaziwayo, eyake yalala phansi izinsuku ezimbalwa kanye nenkonzo ebalulekile yokuqoqa idatha yezokwelapha nge-telemetric, okuhlanganisa nedatha ngesimo senhliziyo seziguli ezisebenzisa i-pacemaker, ezaziqashwe odokotela, abaningana. abantu bafa ... Futhi maduzane, lapho i-Bitrix yethu yenkampani ilele phansi, kwavela ukuthi isizathu sasiwukuthi abasebenzi, ababecisha eminye yemishini, ngenxa ye-typo, bavala ama-node amaningi kunalokho okudingekayo, okuthinta ama-node okuphatha, ngenxa yalokho imishini ebonakalayo yaqala kabusha phakathi namahora angu-5 ngenxa yobukhulu beqoqo elikhulu ... Kodwa lokhu akuyona inkinga engenzeka kuphela; kungase kwenzeke ukuthi uthole "ibhodlela" ngokuzumayo ngenxa yokusetshenziswa. yefu ngamanye amaphrojekthi noma ukuntula amandla okuphatha ngokushesha ingqalasizinda yayo ukuze ihlangabezane nezidingo zakho.
Uma kukhulunywa ngamafu ayimfihlo, ngokombono, i-virtualization yenza kube lula ukutholakala kanye nokubuyiselwa kwezinhlekelele. Empeleni, kunezimo eziningi lapho lokhu kungenangqondo:
Uma kunezinkinga zobuchwepheshe ku-node, isikhathi sokuphumula samaminithi angu-15-30 siyamukeleka.
Akuwona wonke amaphrojekthi adinga isikhathi esicishe sibe ngu-100%, ngaphandle kwezingane zesikole ezijwayele ukukhokha idola futhi ezifuna u-100%. Kwamanye amaphrojekthi, isikhathi esiqinisekisiwe esingu-99,9% singaphezu kwenketho eyamukelekayo. Ngoba i-0,1% ukungatholakali kwemizuzu engama-44 ngenyanga, okungenzeka ngenxa yezizathu ezihlukahlukene ezingahleliwe - ngenxa yokuhluleka kwe-hardware noma ukungatholakali kwenethiwekhi. Siqinisekisa isikhathi sokuphumula senethiwekhi ku-99,99% ngezixazululo ezijwayelekile, okuvumela ukungatholakali kwemizuzu emi-4 kuphela ngenyanga. Uma iseva ixhunywe kumashaneli angu-2 azimele adlula ezindaweni ezihlukene zokuxhumana futhi ithrafikhi yawo icutshungulwa ngama-cores azimele, isikhathi sokuphumula senethiwekhi esiqinisekisiwe sikhuphuka izikhathi eziningana ngaphezulu. Lokhu kwenza kube nokwenzeka ukwanelisa izidingo zesikhathi esengeziwe zamabhange ngisho nokungatholakali kwawo cishe imizuzu engama-40 ngonyaka okwamukelekayo, ngokuhambisana nesitifiketi. Eqinisweni, izikhathi zokungatholakali ziyivelakancane kakhulu. Eminyakeni engu-5 yokusebenza nesikhungo sedatha, akukaze kube khona isikhathi lapho wonke amaseva engatholakali ngesikhathi esifanayo ngenxa yezinkinga zenethiwekhi noma ugesi. Ngisho nalapho kuba nokucinywa komhlaba wonke eNetherlands futhi ezinye izikhungo zedatha eziningi zazingatholakali - ezinye zakhohlwa ukufaka amafutha ezinjinini zikadizili, ezinye zazingenawo amandla anele e-UPS, esikhungweni sethu sedatha angaphansi kwephesenti kuphela lamaseva awazange atholakale isikhashana. isikhathi. Amanye amaseva aqashwa ngamakhasimende kithi, ngisho noma esephelelwe yisikhathi, i-hardware ebonakala isiphelelwe yisikhathi, okungenzeka ukuthi yehluleke kunezixazululo ezintsha ezinophawu, awakaze aqalwe kabusha ngisho nakanye eminyakeni emi-3, njengoba nje eminyakeni emi-3 engakaze alahleke inetha. . Ingabe ukungatholakali kwemizuzu engama-30 kwamukelekile iminyaka emi-3? Ngaphezu kwalokho, ngisho namabhange.
Futhi kuphakama umbuzo onengqondo, kungani-ke ukhokha ngokweqile? Kuyacaca ukuthi akufanele uthembele entuthukweni futhi kufanele uhlale usuka kumgomo wokubhukha okuphusile. Umthetho oyinhloko engiwutholile yilo olandelayo: ukubhukha akufanele kubize ngaphezu kokulahlekelwa okungenzeka uma kwenzeka isikhathi sokungatholakali ngenxa yokuntuleka kwalokho kubhuka. Okusho ukuthi, uma isikhathi sokuphumula esiqinisekisiwe sivumela ukungatholakali kwemizuzu engama-40 ngenyanga, futhi uma kwenzeka ukungatholakali phakathi nesikhathi esinjalo, ukulahlekelwa kuzoba ngamakhulu ambalwa noma inkulungwane yamadola - ukuqasha isisombululo esengeziwe sokwandisa isiqinisekiso sokuphumula kalula. akunangqondo. Ngoba empeleni, amaseva ngeke atholakale njalo ngenyanga imizuzu engama-40; imizuzu engama-40 yokungatholakali isiqinisekiso, isimo esibi kakhulu. Okungenziwa nyanga zonke, njengoba umkhuba ubonisile.
Ngale ndlela, amaseva angabaluleka ngaphandle kokubaluleka komgomo, futhi lapho abanikazi bephrojekthi bengenandaba nokushintsha umthwalo kwenye iseva ezinikezele, singagwema ubunzima bokwakha iqoqo le-faillover kanye nesitoreji esabiwe se-failover.
Ukukhiqiza okuphansi akwamukelekile ngesikhathi sokusebenza. Amakhasimende ethu amaningi akhetha izixazululo zensimbi ezingenalutho kuDell ngenxa yalesi sizathu; ishibhile futhi kunenzuzo enkulu ukusebenzisa i-hardware ephelele ngesikhathi sokusebenza okujwayelekile, okungekho ngaphansi kokungafinyeleleki, njengoba sesixoxile kakade, kunokukhokha ngokweqile ifu. inketho kanye nokusebenza okufanayo efwini, okuzobiza izikhathi eziningana kunesixazululo esizinikezele. Ifu nokuhlanganisa akukwazi nje ukwanelisa izidingo zensiza futhi ngeke kubize kakhulu kumakhasimende anjalo.
Ababhalisile abafuni ukukhokha imali eningi ngesevisi enamandla alinganiselwe. Ikakhulu amakhasimende ethu yizinkampani ezincane ezingenayo iminyango yazo yezobuchwepheshe kanye nezimali zokuthenga i-hardware yazo. Ukuthenga i-hardware kungaba igalelo langempela kubo futhi kunganikezeli ukusebenza okwanele, njengoba ngokuhamba kwesikhathi i-hardware ivame ukuphelelwa yisikhathi, futhi kuyihlazo ukulahla i-hardware ebizayo ngisho nangemva kweminyaka emi-3, ngesikhathi lapho inkampani isikhulile futhi kukhona okungcono kakhulu. okudingekayo. Uma uqasha i-Dell R730xd kithi, unethuba lokushintshela kwenye iseva nganoma yisiphi isikhathi noma ngemva konyaka uma ukhetha inketho yokuqasha ngenkontileka yonyaka. Ngaphezu kwalokho, kunethuba lokonga ekukhokheleni amalayisense e-VMware.
Ukusebenzisa amaseva e-Dell R730xd kumaseva eDatabase
Iningi lamakhasimende ethu asebenzisa lezi ziphakeli zedathabheyisi seliyithanda le nkundla. Futhi hhayi kuphela ngoba, ngokungafani ne-Dell R730, inguqulo ye-xd ingahlinzekwa ngokusekelwa kwamadrayivu e-NVMe PCIe SSD, ahlinzeka ngokubambezeleka okuncane, okubaluleke kakhulu kuzixazululo ezinjalo. Kodwa futhi ngoba isilawuli sisebenza kahle ngendlela emangalisayo uma sisebenza ngisho nama-SSD avamile angu-2,5" esiwanikeza amakhasimende.
Vele, kukhona ne-drawback ku-Dell R730xd - kukhona isilawuli esisodwa kuphela, kuyilapho i-Dell R1 enamadrayivu angama-730 isebenzisa izilawuli ezi-26 zehadiwe. Kodwa lokhu akuyona inkinga ephawulekayo, njengoba sikhethe isiteji esinama-drive bays angu-2 ngakho-ke ngeke uthole ibhodlela ngendlela yokusebenza kwesilawuli esinganele lapho usebenza nale nkundla kanye nenani elikhulu lama-SSD. Futhi inzuzo ngendlela yekhono lokufaka i-NVMe PCIe SSD ihlanganisa ngokuphelele le nkinga.
Njengoba kushiwo ngenhla, akuwona wonke umuntu odinga amaqoqo edatha eyinkimbinkimbi; ukusebenza okungahlinzekwa yile nkundla kubaluleke kakhulu. Elinye lamakhasimende ethu lenze lokho kanye, lashiya ukweqisa kokwenziwa kwezinto ezibonakalayo kanye nokwakha amaqoqo ayinkimbinkimbi, laqasha i-VPS enamadrayivu anikezelwe amakhophi edatha egciniwe avela kuseva enkulu ye-Dell R730xd: Yiqiniso, uma kwenzeka kunenkinga nge-node eyinhloko, kuzoba nokwehla okuthile ekusebenzeni futhi kuzoba nesidingo sokushintsha ngesandla, noma kunjalo, lokhu kuyisixazululo esingaphezu kwezindleko, kunikezwe isabelomali esilinganiselwe.
Asikhuthazi wonke umuntu ukuthi akonge ngale ndlela; kwezinye izimo kufaneleka kakhulu. Kodwa-ke, ngokwandisa isabelomali ngo-$230 kuphela ngenyanga, ungakwazi ukukhokhela i-node efanayo ye-E5-2650 v4 futhi uyixhume ndawonye kunethiwekhi yendawo ye-20-Gigabit, okuzokuvumela ukuthi wakhe iqoqo elincane eline-latency eyamukelekayo. ngisho nangaphandle kokusebenzisa amadrayivu e-PCIe NVMe SSD.
Isixazululo ngokwaso sizobukeka kanje (ngesethi eyisisekelo yamadrayivu):
I-Dell R730xd 2 x Intel Dodeca-Core Xeon E5-2650 v4 128GB DDR4 6x480GB SSD 1Gbps 100 TV + Intel X540-T2 20GBPS LAN β $289/ngenyanga

Ukwandisa isibalo sabo ukuze kwandiswe ukukhiqiza akwenzi mqondo ngaso sonke isikhathi. Ngakho-ke, ngesikhathi sokuhlolwa ngemininingwane yolwazi, sithole ukuthi isixazululo esinama-SSD ayi-8 sisebenza kahle ngo-4% kunesixazululo esinama-SSD ama-35.
Ngokuqondene namazinga e-RAID anconyiwe, i-RAID5 ingase ibe yehle kakhulu kwezinye izimo. Impela, i-RAID10 ihlinzeka ngokusebenza okungcono, kepha kuthiwani uma amadrayivu eshesha kangangokuba ukuwasebenzisa ku-RAID10 kungabangela isilawuli ukuthi sibe yibhodlela? Ezimweni ezinjalo, ukwakha uhlu lwe-HW RAID RAID5 kunenzuzo enkulu usebenzisa amadrayivu ashisayo-ayisipele kune-RAID10 (uma inhloso kungekona ukulahlekelwa ingxenye yesabelo se-SSD).
Ingabe ngidinga inqolobane yesilawuli ukuthi inikwe amandla noma kungcono ukuyikhubaza? Isilawuli se-RAID sinenani elilinganiselwe lememori, iyini i-1GB uma usebenza ne-SSD? Ezimweni ezinama-SSD asheshayo, akukho phuzu ekwenzeni inqolobane yokufunda inikwe amandla, ngoba ngokugcwalisa inkumbulo ngemisebenzi efundwayo, engeke isheshe, njengoba ama-SSD asevele eshesha ngokwanele, asishiyi inqolobane yokubhala eyanele, futhi , njengoba kwaziwa, kuma-SSD angabizi - i-bottleneck yimisebenzi yokubhala, ngenxa yokwehla kokusebenza ngenxa yokunganele kokunikezwa okungaphezu kokwanele kanye no-100% wokusetshenziswa kwesabelo samahhala (ukwehla okuphindwe kashumi kungenzeka). Ngakho-ke, sincoma ukushiya inqolobane yokubhala kuphela enikwe amandla. Ngaleyo ndlela kuqinisekisa ukusebenza kahle okukhulu kwalesi sixazululo.
Ingabe usayizi we-block ye-NTFS unendaba ngempela? Ezinqolobaneni eziningi, i-64KB ikhonjiswe njengosayizi webhulokhi ofanele kakhulu wokusebenza okuphezulu. Kodwa ngokuvamile sihlangabezana nezimo lapho iklayenti selivele lisebenzisa iseva egciniwe, lisebenzisa ukumisa kokuqala ngosayizi ojwayelekile weqoqo le-NTFS elingu-4KB. Ukuze ulungise lokhu udinga ukufometha kabusha amadrayivu, kodwa ingabe umehluko mkhulu kangako esimweni esivamile? Ingabe udinga ukuzichaya esikhathini sokuphumula okungenzeka kanye nokuphazamiseka okuhlobene nokufuduka?
Isilawuli kuseva ye-Dell R730xd sinikeza ukusebenza okuhle okunjalo ngisho namadrayivu angu-4 we-SSD kanye nenqolobane yokubhala inikwe amandla (iphuzu elibaluleke kakhulu, i-cache efundwayo kufanele ikhutshazwe ngoba ayinikezi noma yiziphi izinzuzo, kodwa kunciphisa kuphela ukusebenza kahle kokubhala imisebenzi efanele. ekuntulekeni kwesikhala senqolobane egcwele, njengoba kukhonjisiwe ngenhla), ukuthi ngisho nosayizi webhulokhi ojwayelekile ongu-4KB, sithola izinkomba zokusebenza ezinhle kakhulu, ezinhle kakhulu.
Noma kunjalo, sihlala sizimisele ukuhlangana futhi silungele ukunikeza inkundla efanayo isikhathi esithile ukuze ababhalisile benze umsebenzi uma okuthile bengakunakanga.
I-RAMdrive isabonakala ishesha kunamadrayivu e-SSD. Uma imibuzo yakho ingacutshungulwa ku-TempDB, njengokuhlunga noma ukuhlanganisa, bese usebenzisa i-RAMdisk (uhlelo olushintsha ingxenye ye-RAM yakho ibe isitoreji) kungaba wusizo kakhulu. Ngakho-ke, uma siqhathanisa ijubane lamadrayivu angu-8 we-SSD ku-RAID10 nge-RAMdrive, sithole ukuthi lishesha cishe izikhathi ezi-4 ekusebenzeni kokubhala kwe-4K ngokujula komugqa okungama-32, okulingisa ncamashi ukusebenza kwamafayela e-TempDB. Ngisho nokuhlanganisa ama-SSD angu-8 ku-RAID0 kwakungenakwenzeka ukushaya imiphumela ye-RAMdrive.
I-RAID5 esimweni samadrayivu angu-8 we-SSD ingasebenza kangcono kune-RAID10. Ukufundwa kwe-4K nokujula komugqa okungu-32 cishe kushesha ngo-40%, okungamangazi uma kubhekwa izici ze-RAID5. I-RAID5 iwina ekusebenzeni kwezinye izivivinyo, isibonelo, ngokubhala okulandelanayo ingu-20%, iphansi kuphela emisebenzini yokubhala engu-4K ngokujula komugqa omkhulu (kithi 32) futhi kuvela ingasebenzi kahle ngo-30%. Ngakho-ke ukusetshenziswa kwe-RAID5 kwezinye izimo kungathethelelwa ngokwezomnotho.
Ukulondoloza okwengeziwe akusho ukuthi ngokushesha. Uma sibhekene nemisebenzi emincane engahleliwe, ukwengeza amadrayivu kumalungu afanayo angaphezu komkhawulo othile akuthuthukisi ukusebenza nhlobo. Kungabonakala kungani? Kuvela ukuthi konke kuncike emandleni omlawuli, ophoqeleka ukuthi abhale idatha kuqoqo lonke lokushayela. Kungakho sithenge amapulatifomu anenani eliphakeme lamadrayivu ayi-12, ukuze sinciphise amathuba okuba nebhodlela. Kodwa-ke, udinga ukubheka ukuqina kokusebenza ngaphakathi kwephrojekthi ngayinye, kwesinye isikhathi amadrayivu ama-4 amakhulu, yithi i-960GB, angaba yisixazululo esingcono nesingambi kakhulu kunenqwaba yamadrayivu angama-480GB.
Ukusebenzisa amaseva e-Dell R730xd kumaseva edatha we-Aerospike NoSQL
I-Aerospike iwumthombo ovulekile wedatha ye-NoSQL ene-flash elungiselelwe isivinini nokuqina. I-Aerospike iklanyelwe ukunikeza ukubambezeleka okuphansi kakhulu kwezicelo zokufunda kanye nemithwalo esindayo yokubhala, enelisa izidingo zebhizinisi zesimanje ezidinga ikhono lokusingatha izinombolo ezinkulu zemisebenzi ye-I/O. I-Aerospike ilawula ngokuqondile isitoreji sendawo kuma-cluster node ayo, kungakhathaliseki ukuthi yiziphi izinhlelo zefayela zomthombo wemidiya, kungaba i-DRAM, i-flash noma amadrayivu aqinile endabuko. Lokhu kuvumela idatha ebalulekile ukuthi igcinwe kumidiya eshesha kakhulu lapho ukucubungula okusheshayo kubaluleke kakhulu, kuyilapho imvelo esabalalisiwe ye-database ye-Aerospike iqinisekisa izinga eliphezulu lokuthembeka uma kwenzeka ukuhluleka kwe-cluster node.
Amaseva kaDell wesizukulwane se-13 se-PowerEdge R730xd aletha amandla amangalisayo ekhompiyutha ngamaphrosesa akamuva e-E5-2650 v4 kanye ne-DDR4 SDRAM esheshayo. Futhi amandla okusebenzisa ama-NVMe SSD, afana ne-Samsung SM1715, angasiza ekutholeni ukusebenza okuhle kakhulu nge-latency encane kuma-node anemithwalo ephezulu. Lokhu kwenza kube nokwenzeka ukuhambisana nezidingo ze-SLA zesimanje zesikhathi sokucubungula sokuthengiselana okukodwa ngezinga elithembekile lokuvikelwa ekukhwabaniseni ngisho nasezingomeni zolwazi ezinkulu kakhulu, okwenza isisombululo samukeleke ngisho nakumkhakha wezezimali kanye nokudluliselwa kwebhange, lapho ukuthengiselana ngezinye izikhathi kwenziwa khona. phakathi kwamahora ambalwa noma ngisho nezinsuku.
Ngomkhakha wamabhange, singanikeza isixazululo esisekelwe kulawa mapulatifomu anenethiwekhi yendawo engu-40 kanye ne-100 Gbit / s phakathi kwama-cluster node kanye nokusetshenziswa kwamaswishi afanelekile.
Ukusebenzisa amaseva e-Dell R730xd kumanethiwekhi e-DMZ
Siyajabula ukunikeza ababhalisile bethu izindinganiso eziphakeme kakhulu zokuphepha. Izikhungo zedatha lapho sinikeza khona lawa maseva zinezitifiketi eziningi: , , , ΠΈ .
Kodwa ukuze kuhlangatshezwane nezidingo ze-Google efanayo, amanye amaklayenti adinga ukwakhiwa okuthiwa amanethiwekhi asuswe impi (amanethiwekhi e-DMZ) - amanethiwekhi anokuphepha okukhulisiwe, okusho ukuba khona kwe-firewall yehadiwe ekhawulela ukufinyelela kumishini futhi ikuvumela ukuthi fihla izingxenye ezidingekayo ngemuva kwe-firewall futhi uthuthukise ukuphepha okwengeziwe.
Futhi konke kulungile lapho isixazululo esinjalo siyalwa ngokushesha, kodwa kunzima kakhulu ukuqalisa inguquko ngokungabi nasikhathi sokuphumula kule nqubo, esanda kwenzeka kwelinye lamakhasimende ethu, ngephrojekthi yokucubungula izicelo ze-visa zezakhamizi ezivela emazweni ahlukene. zomhlaba, lapho kungenakufinyeleleka khona ngisho naphakathi namahora kungaholela ekulahlekelweni amashumi ezinkulungwane zamaRandi. Kodwa sathola isixazululo, saya emhlanganweni, sabeka imishini eyengeziwe ekamelweni, sihambisa izinto ezingabalulekile kangako, futhi savula i-firewall ngokuvumelana nesimiso, njengoba iklayenti lalifisa, ukuze likwazi ukufeza ukufuduka ngaphandle kokuphumula.
Kwaba / Kwaba
Mhlawumbe lolu hlelo luzophinde lube usizo kumuntu lapho enza ukufuduka okunjalo, njengoba onjiniyela bezikhungo zedatha abafuni njalo ukubona izinto ezisobala, kodwa bagcizelela ukuthi isikhathi sokuphumula samahora angu-2 ukuze ushintshe ngemuva kwe-firewall, kodwa ngiyakucela ngomusa - oda i-firewall yehadiwe konke kusengaphambili uma uyidinga. Siyavumelana nezimo futhi sihlala sizimisele ukwamukela, kodwa kwezinye izimo amandla ethu angase alinganiselwe.
Ezincwadini ezizayo, sizozama ukwenza ezinye izivivinyo ezengeziwe futhi sabelane ngolwazi olungeziwe sisebenzisa lezi nkundla ezizothuthukisa ukuqonda kokukhethwa kwesixazululo esisebenza kahle kakhulu. Phela, kuyamangaza ukubona iqiniso lokuthi i-RAID0 yamadrayivu amabili e-SSD, ezimeni zolwazi ezinomthwalo omkhulu, ingase ihambe kancane kune-drive drive ehlukile, yingakho sithola izicelo ze-NVMe PCIe SSD kusukela ngesikhathi. kusikhathi. Kungenzeka ukuthi sizobonisa izimo ezisebenza kahle kakhulu zokuqalisa izixazululo, sabelane ngolwazi olwengeziwe lapho sakha amalungu afanayo amaningi e-RAID ngaphakathi kwesilawuli esisodwa se-RAID sisebenza kahle, futhi sibonise ukuthi yiziphi izimo izinhlobo ezimbili ezimele ze-RAID10 zamadrayivu angu-4 zizoba ngcono kunohlu olulodwa lwe-RAID10 lwe 8. Kuzosebenza nini ukusebenzisa i-RAID1 ku-TempDB, kanye ne-RAID5 kukho konke okunye. Futhi ungenza kanjani ngaphandle kwe-NVMe PCIe SSD uma unesabelomali esilinganiselwe.
I-Dell R730xd: ibhonasi yabafundi be-Habrahabr
Sifuna ukukunikeza okungcono kakhulu futhi senze konke ngalokhu ngokukunikeza amanani ahlukile we-Dell R730xd:
- eNetherlands
- nase-USA
Ukucushwa kungahluka kakhulu, isibonelo, Okulandelayo kuyatholakala ukuze kusebenze ngokushesha e-Netherlands::
