Horudhac
Mashruuca isha furan - goob ganacsi oo bilaash ah Ka dib markaan habr dhex maro, ayaan taas ogaaday halkan loogama soo hadal qaadin sida ay mudan tahay.
oVirt dhab ahaantii waa kor u kaca nidaamka ganacsiga ee Koofiyadda Cas Cas (RHV, oo hore u ahaan jirtay RHEV), oo ku koraysa garabka koofiyadda cas. Si looga fogaado jahwareerka, tani ma la mid ah CentOS vs RHEL, moodeel u dhow Fedora vs RHEL.
Koodhka hoostiisa - , Interface web waxaa loo isticmaalaa maamulka. Ku salaysan RHEL/CentOS 7 OS.
oVirt waxaa loo isticmaali karaa labadaba "dhaqameed" server iyo miis-abuurista (VDI), si ka duwan xalka VMware, labada nidaamba waxay ku wada noolaan karaan hal adag.
Mashruucu wuu fiican yahay , waxay muddo dheer gaadhay qaan-gaadhka isticmaalka wax soo saarka waxayna diyaar u tahay culeysyo sarreeya.
Maqaalkani waa kii ugu horreeyay ee taxane ah oo ku saabsan sida loo dhiso koox guuldarraysa oo shaqaynaysa. Markaan soo marnay, waqti gaaban gudaheed (qiyaastii 2 saacadood) waxaan heli doonnaa nidaam si buuxda u shaqeynaya, inkastoo arrimo dhowr ah, dabcan, aan la shaacin doonin, waxaan isku dayi doonaa inaan ku daboolo maqaallada soo socda.
Waxaan isticmaalnay dhowr sano, laga bilaabo nooca 4.1. Nidaamkeena warshadeed wuxuu hadda ku shaqeeyaa HPE Synergy 480 iyo ProLiant BL460c kombiyuutarada jiilka 10aad ee leh Xeon Gold CPU.
Waqtiga qorista, nooca hadda jira waa 4.3.

Tilmaamo shaqeynaya
Waxaa jira 2 qaybood oo waaweyn oo oVirt ah: ovirt-engine iyo ovirt-host(yada). Kuwa aqoonta u leh alaabta VMware, oVirt guud ahaan madal ahaan waa vSphere, ovirt-engine - lakabka xakamaynta - wuxuu qabtaa hawlo la mid ah kan vCenter, iyo ovirt-host waa hypervisor, sida ESX (i). Sababtoo ah vSphere waa xal aad loo jecel yahay, mararka qaarkood waan barbar dhigi doonaa iyada.
Bariis 1 - guddiga xakamaynta oVirt.
Inta badan qaybinta Linux iyo noocyada Windows waxaa loo taageeraa sidii mashiinada martida. Mashiinnada martida waxaa jira wakiilo iyo qalab casri ah oo la hagaajiyay iyo darawallada virtio, ugu horrayn kantaroolaha diskka iyo isku xirka shabakadda.
Si loo hirgeliyo xal-u-dul-qaadka khaladka iyo dhammaan sifooyinka xiisaha leh, waxaad u baahan doontaa kaydinta la wadaago. Labada baloog FC, FCoE, iSCSI, iyo kaydinta feylasha NFS, iwm waa la taageerayaa.Si loo hirgeliyo xal khaladka u dulqaadanayo, nidaamka kaydinta waa inuu noqdaa mid u dulqaadan kara cilladaha (ugu yaraan 2 kontaroolayaal, isku-dhufasho).
Isticmaalka kaydinta maxalliga ah waa suurtagal, laakiin asal ahaan kaydinta la wadaago oo keliya ayaa ku habboon kutlada dhabta ah. Kaydinta maxalliga ahi waxay nidaamka ka dhigaysaa qayb kala duwan oo hypervisors ah, iyo xitaa kaydinta la wadaago, kooxdu lama kulmi karo. Habka ugu saxsan waa mishiinnada aan diskka lahayn ee leh boot ka SAN, ama saxannada cabbirkoodu yar yahay. Malaha, iyada oo loo marayo jilitaanka vdsm, ikhtiyaarka ah in la isku keeno Kaydinta Qeexida Software ee saxannada maxalliga ah (tusaale ahaan, Ceph) oo loo soo bandhigo VM waa suurtagal, laakiin si dhab ah uma tixgelin.
naqshadaha
Bariis 2 - oVirt architecture.
Faahfaahin dheeraad ah oo ku saabsan qaab-dhismeedka ayaa laga heli karaa horumariye.
Bariis 3 - walxaha oVirt.
Cunsurka ugu sarreeya ee kala sareynta waa - Xarunta Macluumaadka. Waxay go'aamisaa in la wadaago ama kaydinta maxaliga ah la isticmaalo, iyo sidoo kale qaabka loo isticmaalo (waafaqsanaan, 4.1 ilaa 4.3). Waxaa jiri kara hal ama ka badan. Doorashooyin badan, adeegsiga Xarunta Xogta ee caadiga ah - Default - ayaa ku habboon.
Xarunta Xogta waxay ka kooban tahay hal ama ka badan Kooxaaha. Kutlada ayaa go'aamisa nooca processor-ka, siyaasadaha socdaalka, iwm. Rakibaadaha yar-yar, waxa kale oo aad naftaada ku xaddidi kartaa kooxda Default.
Kooxdu, iyaduna, waxay ka kooban tahay martigeliyahas kuwaas oo qabta shaqada ugu weyn - waxay wataan mashiinnada farsamada, kaydinta ayaa ku xiran iyaga. Kooxdu waxay qaadataa 2 ama ka badan martigeliyayaal. Inkasta oo ay farsamo ahaan suurtogal tahay in la sameeyo koox leh 1 martigeliyaha, ma aha wax faa'iido ah oo la taaban karo.
oVirt waxay taageertaa hawlo badan, oo ay ku jiraan. guuritaanka tooska ah ee mashiinnada farsamada ee u dhexeeya hypervisors (guurka tooska ah) iyo guuritaanka kaydinta (guuritaanka kaydinta), farsamaynta desktop-ka (kaabayaasha desktop-ka) oo leh barkadaha VM, VMs buuxa iyo dawlad la'aan, taageerada NVidia Grid vGPU, ka soo dejinta vSphere, KVM, waxaa jira a awood leh iyo qaar kaloo badan. Dhammaan sifooyinkaan waxay diyaar u yihiin lacag la'aan royalty, iyo haddii taageero loo baahan yahay, taageerada waxaa laga iibsan karaa Koofiyada Cas iyada oo loo marayo wada-hawlgalayaasha gobolka.
Ku saabsan qiimayaasha RHV
Qiimaha maaha mid sarreeya marka loo eego VMware, kaliya taageerada ayaa la iibsadaa - iyada oo aan loo baahnayn in la iibsado shatiga laftiisa. Taageerada waxaa loo iibsadaa kaliya hypervisors; ovirt-engine, oo ka duwan server-ka vCenter, uma baahna wax kharash ah.
Tusaalaha xisaabinta sanadka 1aad ee lahaanshaha
Aynu tixgelinno koox ka kooban 4 mashiin 2-socket ah iyo qiimaha tafaariiqda (iyada oo aan la dhimin mashruuca).
Isdiiwaangelinta caadiga ah ee RHV sanadkiiba (qiimaha 365/24/7 — $1499), wadarta guud 4*2*$999=$7992.
:
- VMware vCenter Server Standard $10,837.13 tusaale ahaan, oo lagu daray rukunka aasaasiga ah $2,625.41 (wax soo saarka - $3,125.39);
- VMware vSphere Heerka $1,164.15 + Diiwaangelinta aasaasiga ah $552.61 (Soosaarka $653.82);
- VMware vSphere Enterprise Plus $6,309.23 + Diiwaangelinta aasaasiga ah $1,261.09 (Soosaar $1,499.94).
Wadarta: 10 + 837,13 + 2 * 625,41 * (4 + 2) = $ 27 196,62 doorashada ugu yar. Farqiga ayaa ku saabsan 3,5 jeer!
Gudaha oVirt, dhammaan hawlaha waa la heli karaa iyada oo aan xaddidnayn.
Sifooyin kooban iyo ugu badnaan
Shuruudaha nidaamka
Hypervisor-ku wuxuu u baahan yahay CPU oo leh qalab casri ah oo karti leh, qaddarka ugu yar ee RAM si loo bilaabo waa 2 GiB, qaddarka kaydinta lagu taliyey ee OS waa 55 GiB (inta badan logs, iwm., OS laftiisa ayaa qaata wax yar).
Akhri wax dheeraad ah - .
Si aad u Shuruudaha ugu yar ee 2 cores / 4 GiB RAM / 25 GiB kaydinta. Lagu taliyay - laga bilaabo 4 cores/16 GiB RAM/50 GiB kaydinta.
Sida nidaam kasta, waxaa jira xaddidaadyo ku saabsan mugga iyo tirada, kuwaas oo intooda badan ka sarreeya awoodaha server-yada ganacsiga ee la heli karo. Haa, lamaane wuxuu wax ka qaban karaa 2 TiB ee RAM wuxuuna siinayaa 40 cores (80 threads), taas oo ka yar xitaa xadka hal VM.
Inta ugu badan ee Mashiinka Farshaxanka:
- Mashiinnada farsamada gacanta ee ugu badan: Unlimited;
- CPU-yada ugu badan ee mashiinnada casriga ah: 384;
- Xusuusta ugu badan ee mashiinka farsamada: 4 TiB;
- Cabbirka ugu badan ee hal saxan halkii mashiinka farsamada: 8 TiB.

- Socdaalka tooska ah ee isku mar ah: 2 soo galaya, 2 baxay;
- Baadhitaanka socdaalka tooska ah: Ku-salaysan 52 MiB (~436 Mb) guurkiiba marka la isticmaalayo siyaasadda socdaalka ee dhaxalka ah. Nidaamyada kale waxay adeegsadaan qiyamka wax-soo-saarka la-qabsiga ee ku saleysan xawaaraha aaladda jireed. Siyaasadaha QoS waxay xaddidi karaan xawaaraha socdaalka.

- Cabbirka saxanka ugu badan: 500 TiB (ku xaddidan yahay 8 TiB ahaan ahaan).
Doorashooyinka hirgelinta
Sida hore loo sheegay, oVirt waxa laga dhisay 2 walxood oo asaasi ah - ovirt-engine (control) iyo ovirt-host (hypervisor).
Matoorku wuxuu ku yaalaa meel ka baxsan goobta lafteeda (Maareeye kali ah - tani waxay noqon kartaa VM ku shaqeeya goob kale ama hypervisor gaar ah, ama xitaa mashiinka jireed) ama goobta lafteeda (matoorka iskiis u maamula, oo la mid ah habka VCSA). ka VMware).
Hypervisor-ka ayaa lagu rakibi karaa labadaba ( EL Host ), iyo kor (oVirt-Node, oo ku salaysan el7).
Shuruudaha qalabka ee dhammaan xulashooyinka waa isku mid.
Bariis 4 - naqshadaha caadiga ah.
Bariis 5 - Naqshadeynta Injineerka oo iskii u maamulay.
Naftayda waxa aan doortay maamulaha goonida ah iyo EL Hosts:
- Maareeye kali ah ayaa wax yar ka fudud marka ay timaado dhibaatooyinka bilowga, ma jiraan digaag iyo ukumo adag (sida VCSA - ma bilaabi kartid ilaa ugu yaraan hal marti si buuxda u kacayo), laakiin waxaa jira ku tiirsanaanta nidaam kale *;
- EL Host wuxuu bixiyaa dhamaan awooda OS, kaas oo faa'iido u leh la socodka dibadeed, wax ka saarista, cilad-baadhista, iwm.
* Si kastaba ha ahaatee, inta lagu guda jiro dhammaan muddada hawlgalka tani looma baahna, xitaa ka dib markii korontadu xumaato.
Laakiin aan gaadhno nuxurka!
Tijaabada, waxa suurtagal ah in la sii daayo lammaane ProLiant BL460c G7 ah oo wata Xeon® CPU. Waxaan u isticmaali doonaa si aan u soo saarno habka rakibidda.
