Iziphumo zovavanyo zibonisa ukuzuzwa okubonakalayo kokusebenza kwamaqonga eDell R730xd xa usebenzisa iSanDisk DAS cache caching xa kuthelekiswa neHPE SmartCache, kunye neNVMe PCIe SSD inkxaso ibonelela ngeenzuzo ezinkulu ngakumbi. Kwimifuziselo ye-OLTP, i-R730xd ibonise ukuya kumaxesha e-3 aphezulu e-IOPS ngenxa yokusetyenziswa kweSanDisk DAS Cache kunye ne-SAS SSDs kunye namaxesha angama-6 aphezulu ngenxa yokusetyenziswa kweSanDisk DAS Cache + NVMe PCIe SSDs xa kuthelekiswa ne-HPE's SmartCache. Ukusetyenziswa kweCPU ephezulu kunye neSanDisk DAS Cache, kunye nokusetyenziswa kweCPU ephezulu neSanDisk DAS Cache + NVMe PCIe SSDs, sisiphumo nje sokubala okuphezulu kwe-IOPS. kwaye, ngokuchaseneyo, ibonisa ukusetyenziswa ngokufanelekileyo kwemithombo yeprosesa.
Ngoko ke, ukuba kwi-HP kunye ne-6% yokusetyenziswa isiphumo se-IOPS singama-41 amawaka, oko kukuthi, i-1% yemithombo yeprosesa idliwe nge-0,15 yewaka le-IOPS, ngoko kwimeko ye-Dell R730xd sine-16% yokusetyenziswa kwi-264 lamawaka, apho. inikeza isalathisi esisebenzayo - i-0,06% yezibonelelo zeprosesa nge-1000 IOPS.
Oko kukuthi, malunga nokusetyenziswa kweprosesa, iDell iphinde ibonakale ingcono (i-2,5 amaxesha), nangona inamaxabiso okusetyenziswa kweprosesa aphezulu, kodwa, njengoko siye sakwazi ukuqinisekisa, oku kuphela sisiphumo sokusebenza. inani elikhulu kakhulu lemisebenzi, kwaye ke ngoko imveliso engcono.
Ngaloo ndlela, i-platform ye-Dell R730xd ijika ibe yinto efanelekileyo kakhulu kune-HP ProLiant DL380 (izihlandlo ezininzi), zombini ngokubhekiselele ekusebenzeni kunye nokusebenza kweendleko.
Iziphumo ze-Geekbanch 3 test Dell R730xd nge-E5-2640 v4 iprosesa okanye kutheni imiyalelo yeprosesa kunye ne-cache yomlawuli ibalulekile
Njengoko sibona ngasentla, sinokufikelela kwiziphumo eziphezulu kuphela xa amacandelo amathathu - amandla e-computing, ukugcinwa kunye nothungelwano - alungelelaniswa, njengoko iibhotile ezinokuthi zenzeke kwinkqubo engalinganiyo ziyancitshiswa.
Kodwa eyona nto ibaluleke kakhulu yinkxaso yeprosesa yeqonga kwinani lemiyalelo kunye nokusebenza kwayo. Sele ndikhankanyile ngasentla ukuba umahluko obonakala ungabalulekanga kwizizukulwana unokudlala indima ebalulekileyo kwezinye iimeko. Ngaloo ndlela, ngokweziphumo zeemvavanyo ezizimeleyo, i-E5-2650 v4 esibonelela ngayo i-70% iphumelele ngakumbi kwimeko ye-encryption (imiyalelo ye-AES) kune-E5-2650 v3.
Kuthiwani ke malunga nezisombululo "ezimnandi" ezivela kubakhuphisana neendleko eziphantsi, kodwa kungekhona icandelo le-premium? Kutheni izisombululo zethu zingcono? Kutheni izisombululo zethu ziyipremiyamu? Impendulo ilula - abancedisi bethu babe kwaye balungelelene. Nokuba bebefudula beneziza ezisezantsi okanye iinkumbulo ezincinci, bezisoloko zilungelelana ngokweeparamitha ezintathu ezichazwe ngasentla. Kubandakanya iziko ledatha elithembekileyo elinezatifikethi ezifunwa licandelo leshishini kunye neendlela ezigqwesileyo zonxibelelwano lwangaphandle ezibonelela nge-latency encinci ukusuka eNetherlands, ukuya kulo lonke elaseYurophu, ukuya eRussia naseUkraine, kwaye nkqu.
Kodwa ngoku senze umnikelo wokukhuphisana ngokwezi zalathisi, kwiindawo ze-10 kanye, enye eNetherlands kunye neendawo ze-9 e-USA, kodwa masingathethi ngathi, makhe sijonge uvavanyo. Ngelishwa, olu vavanyo okwangoku lufumaneka kuphela kwinguqulo ye-E5-2640 v4, ene-10, kungekhona i-12 cores, kwiqonga lethu.
Ngokuqinisekileyo, ayisiyonjongo kakhulu, kuba ayithatheli ngqalelo zonke izibonelelo zeqonga, i-cache efanayo ye-SanDisk DAS ebesithetha ngayo, iimpawu zokusebenza zokwenyani zinokujika zibe ngcono kakhulu kunezokwenziwa kwindawo ethile. ityala, kakhulu! Kodwa kusenokwenzeka ukuzuza ukuqonda okuthile.
Masinikele ingqalelo kwimiyalelo emininzi. Eyona nto ibonakalisayo inokuba yi-AES esele ikhankanyiwe, malunga nee-frequencies ezifanayo umahluko phakathi kwamaxabiso e-1st core unokuya kuthi ga kumaxesha angama-1000 ngokuxhomekeke kwiprosesa, imiyalelo eseleyo ethe yathelekiswa yabonisa umahluko kumaxabiso avela kwiprosesa. amaxesha amaninzi ukuya kwi-100.
Unokwenza ngokwakho kwaye wenze uthelekiso, kodwa ungalibali ukuba olu vavanyo alubonakali ngokupheleleyo, kuba aluyithatheli ngqalelo i-hardware iyonke, kodwa ikakhulu ibonakalisa iprosesa.
Nangona kunjalo, ndiyathemba ukuba ezi ziphumo zinokuba luncedo kuwe xa uhlalutya ukusebenza kwesisombululo esithile.
Ukusebenzisa iiseva zeDell R730xd njengeBare Metal, ngcono nje!
Abanye babaxumi bethu bagqibe kwelokuba bayeke ukusebenzisa izisombululo zelifu le-VMware ngokuthanda izisombululo zeBare Metal (iiseva zentsimbi) kunye neqonga le-Dell R730xd labanceda kakhulu kule nto. Kwaye apha asithethi kuphela ngamafu oluntu, kodwa nangabucala.
Kutheni besanda abantu besenza ezo zigqibo? Ngokuphathelele amafu oluntu, yonke into icacile ngakumbi. Mna ngokwam ndijonga amafu oluntu njengentengiso enkulu, ukuba kukho into ewela apho (kwaye onke amafu awela kungekudala okanye kamva), iwela apho ixesha elide. Umzekelo ngulo waziwa kakhulu yiAmazon, eyathi ngaxesha lithile yalala phantsi kangangeentsuku ezininzi kunye nenkonzo ebalulekileyo yokuqokelela idatha yezonyango ye-telemetric, kubandakanya nedatha ekwimeko yentliziyo yezigulana ezisebenzisa i-pacemaker, ezazijongwe ngoogqirha, uninzi lwazo. abantu bafa ... Kwaye kungekudala, xa i-Bitrix yethu yenkampani yayilele phantsi, kwavela ukuba isizathu kukuba abasebenzi, ababecima abanye oomatshini, ngenxa ye-typo, bacima iindawo ezininzi kunokuba ziyimfuneko, echaphazela iindawo zolawulo, ngenxa yoko oomatshini bokwenyani baphinde baqalwa kwakhona kwiiyure ze-5 ngenxa yobukhulu beqela elikhulu ... Kodwa oku akusiyo kuphela ingxaki enokwenzeka; kunokwenzeka ukuba ngokukhawuleza ufumane "i-bottleneck" ngenxa yokusetyenziswa. yelifu ngezinye iiprojekthi okanye ukunqongophala kwamandla okulawula ngokukhawuleza amaziko ayo ukuhlangabezana neemfuno zakho.
Xa kuziwa kumafu abucala, kwithiyori, i-virtualization yenza lula ukufumaneka kunye nokubuyisela intlekele. Enyanisweni, kukho iimeko ezininzi apho oku kungenangqondo:
Kwimeko yeengxaki zobuchwepheshe kwi-node, i-15-30 iminithi yokuphumla iyamkeleka.
Ayizizo zonke iiprojekthi ezifuna ixesha elimalunga ne-100%, ngaphandle kwabantwana besikolo abaqhele ukuhlawula idola kwaye bafuna i-100%. Kwezinye iiprojekthi, ixesha eliqinisekisiweyo le-99,9% lingaphezulu kokhetho olwamkelekileyo. Ngenxa yokuba i-0,1% kukungafumaneki kobuninzi bemizuzu engama-44 ngenyanga, enokuthi yenzeke ngenxa yezizathu ezahlukeneyo ezingacwangciswanga - ngenxa yokungaphumeleli kwe-hardware okanye ukungabikho kwenethiwekhi. Siqinisekisa i-network uptime kwi-99,99% yezisombululo eziqhelekileyo, ezivumela ukungafumaneki kwemizuzu ye-4 kuphela ngenyanga. Ukuba umncedisi uqhagamshelwe kwii-2 iziteshi ezizimeleyo ezidlula kwiindawo ezahlukeneyo zonxibelelwano kwaye i-traffic yayo icutshungulwa ngama-cores azimeleyo, i-uptime yenethiwekhi eqinisekisiweyo iyanda ngokuphindaphindiweyo. Oku kwenza kube nokwenzeka ukwanelisa iimfuno zexesha lokusebenza nkqu neebhanki apho ukungafumaneki malunga nemizuzu engama-40 ngonyaka kwamkelekile, ngokungqinelana nesiqinisekiso. Enyanisweni, amaxesha okungabikho anqabile kakhulu. Kwiminyaka emi-5 yokusebenza kunye neziko ledatha, akuzange kubekho ixesha apho zonke iiseva zingabikho ngexesha elifanayo ngenxa yeengxaki zenethiwekhi okanye umbane. Kwanaxa kwakukho ukucima kwehlabathi jikelele eNetherlands kwaye amanye amaziko edatha amaninzi awazange afumaneke - abanye balibale ukufaka amafutha kwiinjini zedizili, abanye babengenawo amandla aneleyo e-UPS, kwiziko lethu ledatha ngaphantsi kweepesenti zeeseva azifumaneki ixesha elifutshane. ixesha lexesha. Ezinye zeeseva eziqeshiswa ngabathengi kuthi, nokuba ziphelelwe lixesha, ezibonakala ngathi ziphelelwe lixesha, ezinokuthi zisilele kunezisombululo ezitsha ezinophawu, azikaqaliswa kwakanye kwiminyaka emi-3, njengokuba kwiminyaka emi-3 azizange zilahleke. . Ngaba ukungafumaneki kwemizuzu engama-30 kwamkelekile kwiminyaka emi-3? Ngaphezu koko, nakwiibhanki.
Kwaye kuphakama umbuzo onengqiqo, kutheni ke ukuhlawula ngaphezulu? Ihamba ngaphandle kokutsho ukuba akufuneki uthembele kwithuba kwaye kufuneka usoloko uqhubeka kumgaqo wogcino-ndawo olufanelekileyo. Umgaqo ophambili endiwufumeneyo ngulo ulandelayo: Ugcino kufuneka lungabi ngaphezu kwelahleko enokuthi yenzeke kwimeko yokungabikho kwexesha ngenxa yokunqongophala koko kugcinwa. Oko kukuthi, ukuba ixesha eliqinisekisiweyo livumela ukungafumaneki kwemizuzu engama-40 ngenyanga, kwaye kwimeko yokungafumaneki ngexesha elinjalo, ilahleko iya kuba ngamakhulu aliqela okanye iwaka leedola - ukurenta isisombululo esongezelelweyo sokwandisa isiqinisekiso sokuphela kwexesha. ayinangqondo. Kuba eneneni, iiseva aziyi kufumaneka rhoqo ngenyanga ngemizuzu engama-40; imizuzu engama-40 yokungafumaneki sisiqinisekiso, eyona meko imbi kakhulu. Ayiphunyezwa qho ngenyanga, njengoko kubonisiwe.
Ngale ndlela, iiseva zinokubaluleka ngaphandle kokubaluleka kobuthunywa, kwaye xa abanini beprojekthi bengenangxaki ngokutshintshela umthwalo komnye umncedisi ozinikeleyo, sinokunqanda ubunzima bokwakha iqela le-faillover kunye nokugcinwa okwabelwana ngayo.
Imveliso ephantsi ayimkelekanga ngexesha lokusebenza. Uninzi lwabathengi bethu bakhetha izisombululo zentsimbi ezingenanto kwiDell ngokuchanekileyo ngenxa yesi sizathu; kubiza kakhulu kwaye kunenzuzo ngakumbi ukusebenzisa i-hardware epheleleyo ngexesha lokusebenza okusemgangathweni, okungekho phantsi kokungafikeleleki, njengoko sele sixoxile, kunokuhlawula ngaphezulu kwelifu. ukhetho kunye nokusebenza okufanayo kwilifu, eliya kubiza amaxesha amaninzi ngaphezu kwesisombululo esizinikeleyo. Ilifu kunye nokudibanisa ngokulula akunakukwanelisa iimfuno zezibonelelo kwaye aziyi kuba neendleko ezisebenzayo kubathengi abanjalo.
Ababhalisi abafuni ukuhlawula kakhulu ngenkonzo enezakhono ezilinganiselweyo. Ubukhulu becala abathengi bethu ziinkampani ezincinci ezingenawo amasebe abo obugcisa kunye nenkxaso-mali yokuthenga izixhobo zabo zekhompyutha. Ukuthenga i-hardware kunokuba sisibetho sokwenyani kubo kwaye kungaboneleli ngokusebenza okwaneleyo, kuba ngokuhamba kwexesha i-hardware idla ngokuphelelwa lixesha, kwaye kulihlazo ukulahla izixhobo ezibiza kakhulu nasemva kweminyaka emi-3, ngexesha apho inkampani ikhule kwaye into engcono. efunekayo. Ukuba urenta i-Dell R730xd kuthi, unethuba lokutshintshela kwenye iseva nangaliphi na ixesha okanye emva konyaka ukuba ukhetha ukhetho lokurenta ngesivumelwano sonyaka. Ngaphezu koko, kukho ithuba lokonga ekuhlawuleleni iilayisensi zeVMware.
Ukusebenzisa iiSeva zeDell R730xd kwiiSeva zeDatabase
Uninzi lwabathengi bethu abasebenzisa ezi seva zedatha baye bathanda eli qonga. Kwaye kungekuphela ngenxa yokuba, ngokungafaniyo ne-Dell R730, inguqulo ye-xd inokunikezelwa ngenkxaso ye-NVMe PCIe SSD drives, ebonelela nge-latency encinci, ebaluleke kakhulu kwizisombululo ezinjalo. Kodwa nangenxa yokuba isilawuli sisebenza ngokumangalisayo xa sisebenza nakwii-SSD eziqhelekileyo eziyi-2,5 β³ esizinikezela kubathengi.
Kakade ke, kukho kwakhona i-drawback kwi-Dell R730xd - kukho umlawuli we-1 kuphela, ngelixa i-Dell R730 ene-26 drives isebenzisa abalawuli be-hardware aba-2. Kodwa oku akuyona ingxaki ebalulekileyo, ekubeni sikhethe iqonga elinama-drive bays angama-12 kwaye ngoko awuyi kufumana ibhotile ngendlela yokungasebenzi ngokwaneleyo komlawuli xa usebenza neli qonga kunye nenani elikhulu le-SSD. Kwaye inzuzo ngendlela yokukwazi ukufaka i-NVMe PCIe SSD igubungela ngokupheleleyo le ngxaki.
Njengoko kukhankanyiwe ngasentla, ayinguye wonke umntu ofuna iqoqo ledatha entsonkothileyo; ukusebenza elinokubonelela ngeqonga kubaluleke kakhulu. Omnye wabaxumi bethu uye wenza kanye loo nto, wayeka ukugqwesa kokubonwayo kunye nokwakha amaqela anzima, waqesha iVPS eneedrive ezinikezelweyo zokugcinwa kwedatha kwi-Dell R730xd iseva: Ngokuqinisekileyo, xa kukho ingxaki nge-node ephambili, kuya kubakho ukuhla kwentsebenzo kwaye kuya kuba nesidingo sokutshintshwa kwencwadana, nangona kunjalo, oku kungaphezu kwesisombululo esinendleko, sinikwe uhlahlo lwabiwo-mali olulinganiselwe.
Asikhuthazi wonke umntu ukuba akonge ngolo hlobo; kwezinye iimeko ide ithetheleleke kakhulu. Nangona kunjalo, ngokunyusa uhlahlo lwabiwo-mali nge-$ 230 kuphela ngenyanga, unako ukuthenga i-node ye-E5-2650 v4 efanayo kwaye udibanise kunye nenethiwekhi yendawo ye-20-Gigabit, leyo, ngokomgaqo, iya kukuvumela ukuba wakhe i-cluster encinci kunye ne-latency eyamkelekileyo. ngaphandle kokusetyenziswa kwe-PCIe NVMe SSD drives.
Isisombululo ngokwaso siya kujongeka ngolu hlobo (kunye neeseti ezisisiseko zokuqhuba):
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 inani labo ukwandisa imveliso akusoloko kunengqiqo. Ngaloo ndlela, ngexesha lovavanyo kunye nedathabheyisi, sifumene ukuba isisombululo kunye ne-8 SSDs kuphela i-4% esebenzayo ngaphezu kwesisombululo kunye ne-35 SSDs.
Ngokuphathelele amanqanaba e-RAID acetyiswayo, i-RAID5 inokuba yeyona ilungileyo kwezinye iimeko. Ngokuqinisekileyo, i-RAID10 ibonelela ngokusebenza okungcono, kodwa kuthekani ukuba iidrive zikhawuleza kangangokuba ukuzisebenzisa kwi-RAID10 kunokubangela ukuba umlawuli abe ngumqobo? Kwiimeko ezinjalo, ukwakha i-HW RAID uluhlu lwe-RAID5 kunenzuzo eninzi kakhulu usebenzisa iidrive ezitshisayo kune-RAID10 (ukuba injongo ayikokulahlekelwa sisiqingatha se-SSD).
Ngaba ndifuna ukuba i-cache yomlawuli yenziwe ukuba isebenze okanye kungcono ukuyicima? Umlawuli we-RAID unomlinganiselo omncinci wememori, yintoni i-1GB xa usebenza ne-SSD? Kwiimeko ezine-SSD ezikhawulezayo, akukho sizathu sokuba i-cache yokufunda isebenze, kuba ngokuzalisa imemori ngemisebenzi yokufunda, engayi kuba ngokukhawuleza, kuba ii-SSD sele zikhawuleza ngokwaneleyo, asishiyi i-cache yokubhala ngokwaneleyo, kwaye , njengoko kwaziwa, kwii-SSD ezingabizi kakhulu - i-bottleneck yimisebenzi yokubhala, ngenxa yokuhla kwentsebenzo ngenxa yokungonelanga kokubonelela ngokugqithisileyo kunye ne-100% yokusetyenziswa kwe-quota yamahhala (ukuhla kweshumi kunokwenzeka). Ngoko ke, sincoma ukushiya kuphela i-cache yokubhala evuliwe. Ngoko ke kuqinisekiswa ukusebenza kakuhle kwesi sisombululo.
Ngaba ubungakanani bebhloko ye-NTFS ibalulekile ngokwenene? Kwiindawo ezininzi zokugcina, i-64KB ibonakaliswe njengeyona sayizi yebhloko efanelekileyo yokusebenza okuphezulu. Kodwa kaninzi sidibana neemeko apho umxhasi sele esebenzisa iseva yedatha, esebenzisa uqwalaselo lokuqala ngobungakanani beqela leNTFS eliqhelekileyo le-4KB. Ukulungisa oku kufuneka ulungise ngokutsha iidrives, kodwa ngaba umahluko mkhulu kakhulu kwimeko jikelele? Ngaba kufuneka uzibeke esichengeni sexesha lokuphumla elinokwenzeka kunye nokuphazamiseka okunxulumene nokufuduka?
Umlawuli kwi-Dell R730xd umncedisi unikeza ukusebenza kakuhle okunjalo kunye ne-4 SSD drives kunye ne-cache yokubhala inikwe amandla (inqaku elibaluleke kakhulu, i-cache yokufunda kufuneka ikhutshazwe ngenxa yokuba ayinikezeli nayiphi na inzuzo, kodwa inciphisa kuphela ukusebenza kokubhala ngokufanelekileyo. ukunqongophala kwendawo ye-cache epheleleyo, njengoko kubonisiwe ngasentla), ukuba nangona ubungakanani bebhloko esemgangathweni ye-4KB, sifumana izikhombisi zokusebenza ezilungileyo kakhulu, zilunge kakhulu.
Nangona kunjalo, sihlala sikulungele ukudibana kwaye sikulungele ukubonelela ngeqonga elifanayo kangangexesha elithile ukuze ababhalisile benze umsebenzi ukuba kukho into engathathelwa ngqalelo ngabo.
I-RAMdrive isajika ngokukhawuleza kunee-SSD drives. Ukuba imibuzo yakho inokucutshungulwa kwi-TempDB, njengokuhlela okanye ukudibanisa, emva koko usebenzisa i-RAMdisk (inkqubo ejika inxalenye ye-RAM yakho kwindawo yokugcina) inokubaluleka kakhulu. Ke, xa sithelekisa isantya se-8 SSD sokuqhuba kwi-RAID10 kunye ne-RAMdrive, siye safumanisa ukuba imalunga namaxesha ama-4 ngokukhawuleza kwemisebenzi yokubhala ye-4K enobunzulu bomgca wama-32, elinganisa ngokuthe ngqo ukusebenza kweefayile ze-TempDB. Nangona ukudibanisa i-8 SSDs kwi-RAID0 kwakungenakwenzeka ukubetha iziphumo ze-RAMdrive.
I-RAID5 kwimeko ye-8 SSD drives inokusebenza ngakumbi kune-RAID10. I-4K ifundeka ngobunzulu bomgca we-32 malunga ne-40% ngokukhawuleza, oko akumangalisi ukuba kunikwe iimpawu ze-RAID5. I-RAID5 iphumelele ekusebenzeni kwezinye iimvavanyo, umzekelo, ngokubhala ngokulandelelana yi-20%, iphantsi kuphela kwimisebenzi yokubhala ye-4K kunye nobunzulu obukhulu bomgca (kwimeko yethu ye-32) kwaye ivele ingasebenzi kakuhle nge-30%. Ke ukusetyenziswa kwe-RAID5 kunokuthi kwezinye iimeko kuthetheleleke ngokwezoqoqosho.
Ugcino oluninzi alusoloko luthetha ngokukhawuleza. Xa sijongene nemisebenzi emincinci engaqhelekanga, ukongeza iidrives kuluhlu ngaphaya komda othile akuphuculi ukusebenza konke. Kuya kubonakala ukuba kutheni? Kuvela ukuba yonke into ixhomekeke kwizakhono zomlawuli, onyanzelekileyo ukuba abhale idatha kwi-bunch yonke yokuqhuba. Yiyo loo nto sithenge amaqonga anobuninzi be-12 drives, ukuze kuncitshiswe ukubakho kwe-bottleneck. Nangona kunjalo, kufuneka ujonge ubunzulu bemisebenzi ngaphakathi kweprojekthi nganye, ngamanye amaxesha iidrive ezi-4 ezinkulu, yithi i-960GB, inokuba sisisombululo esingcono nesinendleko enkulu kuneqela le-480GB drives.
