Horudhac
Mashruuca isha furan - goob ganacsi oo bilaash ah Ka dib markaan Habr dhex maray, ayaan taas ogaaday halkan loogama soo hadal qaadin inta ay mudan tahay.
oVirt asal ahaan waa goob sare oo loogu talagalay nidaamka ganacsi ee Koofiyada Cas (RHV, oo hore u ahaan jiray RHEV), kuna koraya dallada koofiyadda cas. Si looga fogaado jahwareerka, tani ma isla sidii CentOS vs RHEL, qaabka u dhow Fedora vs RHEL.
Koodhka hoostiisa - , shabakad is-dhexgal ah ayaa loo isticmaalaa maaraynta. Waxay ku salaysan tahay RHEL OS/CentOS 7.
oVirt waxaa loo isticmaali karaa labadaba "caado ah" server iyo miis-abuurista (VDI); Si ka duwan xalka VMware, labada nidaamba waxay ku wada noolaan karaan hal adag.
Mashruucu wuu fiican yahay , ayaa muddo dheer tan iyo markii ay gaadhay qaan-gaadhka isticmaalka waxtarka leh waxayna diyaar u tahay culeysyo sarreeya.
Maqaalkani waa kii ugu horreeyay ee taxane ah oo ku saabsan sida loo dhiso koox guuldarraysa oo shaqaynaysa. Marka la raaco tillaabooyinkan, waxaan ku yeelan doonnaa nidaam si buuxda u shaqeeya muddo gaaban (qiyaastii laba saacadood). In kasta oo ay jiraan arrimo dhawr ah oo aan si buuxda loo dabooli doonin, waxaan isku dayi doonaa inaan kaga hadlo maqaallada mustaqbalka.
Waxaan isticmaalnay dhowr sano, laga bilaabo nooca 4.1. Nidaamkeena warshadeed wuxuu hadda ku shaqeeyaa HPE Synergy 480 iyo jiilka 10-aad ee ProLiant BL460c kombiyuutarada oo wata Xeon Gold CPUs.
Waqtiga qorista, nooca hadda jira waa 4.3.

Tilmaamo shaqeynaya
oVirt waxay leedahay laba qaybood oo waaweyn: ovirt-engine iyo ovirt-host(yada). Kuwa yaqaana alaabada VMware, oVirt madal ahaan waa vSphere. ovirt-engine-lakabka maamulka-wuxuu qabtaa isla hawlaha vCenter, iyo ovirt-host waa hypervisor, oo la mid ah ESX(i). Maadaama vSphere uu yahay xal aad loo jecel yahay, waxaan mararka qaarkood bixin doonaa isbarbardhigga.
Jaantuska 1 - kontoroolka oVirt.
Qaybinta badankood waxaa loo taageeraa mashiinno marti ah. Linux iyo noocyada WindowsMashiinnada martida, waxaa jira wakiillo iyo qalabyo casri ah oo la habeeyay iyo darawallo virtio ah, gaar ahaan kontoroolka diskka iyo isku-xirka shabakadda.
Si loo hirgeliyo xal-u-dulqaadka cilada iyo dhammaan sifooyinka xiisaha leh, kaydinta la wadaago ayaa loo baahan yahay. Block-based FC, FCoE, iSCSI, iyo NFS kaydinta faylka waa la taageerayaa, oo ay la socdaan xulashooyinka kaydinta kale. Si loo hirgeliyo xal u dulqaadashada cilada, nidaamka kaydinta waa inuu sidoo kale ahaadaa mid u dulqaadan kara cilladaha (ugu yaraan laba kontaroolayaal, isku-dhufasho).
Isticmaalka kaydinta maxalliga ah waa suurtagal, laakiin asal ahaan, kaydinta la wadaago oo keliya ayaa ku habboon kutlada dhabta ah. Kaydinta maxaliga ahi waxay nidaamka ka dhigtaa mid kala duwan oo hypervisors ah, iyo xitaa kaydinta la wadaago, ururintu ma shaqayn doonto. Habka ugu fiican waa mishiinnada disk-laawayaasha ah oo ka soo boodaya SAN, ama isticmaalaya saxannada cabbirkoodu yar yahay. Waa suurtogal in la isticmaalo jilbaha vdsm si loo dhiso Kaydinta Qeexsan Software (tusaale, Ceph) saxannada maxalliga ah oo loo soo bandhigo VM, laakiin si dhab ah ugama tixgelin.
naqshadaha
Jaantuska 2 - dhismaha oVirt.
Macluumaad dheeraad ah oo ku saabsan qaab-dhismeedka ayaa laga heli karaa horumariye.
Jaantuska 3 - walxaha oVirt.
Cunsurka ugu sarreeya ee kala sareynta waa Xarunta MacluumaadkaWaxay go'aamisaa in la wadaago ama kaydinta maxaliga ah la isticmaalo, iyo sidoo kale qaabka loo isticmaalo (waafaqsanaan, laga bilaabo 4.1 ilaa 4.3). Waxaa jiri kara hal ama ka badan. Xaalado badan, Xarunta Xogta ee caadiga ah ayaa ku habboon.
Xarunta Xogta waxay ka kooban tahay hal ama ka badan KooxaahaKutlada ayaa go'aamisa nooca processor-ka, siyaasadaha socdaalka, iwm. Rakibaadaha yaryar, kooxda Default sidoo kale waa la isticmaali karaa.
Kooxdu, iyaduna, waxay ka kooban tahay martigeliyahas kuwaas oo qabta shaqada ugu muhiimsan - waxay martigeliyaan mashiinada farsamada waxayna leeyihiin kayd ku xiran iyaga. Kooxdu waxay u baahan tahay laba ama ka badan martigeliyaha. In kasta oo ay farsamo ahaan suurtogal tahay in la abuuro koox leh hal marti-geliyaha, ma aha wax la taaban karo.
oVirt waxay taageertaa sifooyin kala duwan, oo ay ku jiraan guuritaanka tooska ah ee mashiinnada farsamada ee u dhexeeya hypervisors iyo 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, iyo awood xoog leh iyo qaar kaloo badan. Dhammaan sifooyinkan waa kuwo la heli karo royalty-la'aan, waxaana taageerada laga heli karaa Koofiyada Cas iyada oo loo marayo wada-hawlgalayaasha gobolka haddii loo baahdo.
Ku saabsan qiimayaasha RHV
Qiimaha waa yar yahay marka loo eego VMware; kaliya waxaad iibsataa taageero, adoon u baahnayn inaad iibsato shati. Taageerada waxaa loo iibsadaa oo keliya hypervisors; Si ka duwan Server-ka vCenter, matoorka ovirt-ku uma baahna kharash dheeraad ah.
Tusaale xisaabinta sanadka ugu horeeya ee lahaanshaha
Aynu tixgelinno koox ka kooban 4 mashiin 2-socket ah iyo qiimaha tafaariiqda (iyada oo aan la dhimin naqshadeynta).
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 * (1,164.15 + 552,61) = $ 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, ugu yaraan RAM oo ah 2 GiB si loo bilaabo, iyo cabbirka kaydinta lagu taliyey ee OS ee 55 GiB (inta badan logs, iwm. OS laftiisa ayaa qaadata meel yar).
Faahfaahin dheeraad ah - .
Si aad u Shuruudaha ugu yar: 2 cores / 4 GiB RAM / 25 GiB kaydinta. Lagu taliyay: 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 suuqa-weyn ee la heli karo. Tusaale ahaan, lamaane wuxuu wax ka qaban karaa 2 TiB ee RAM wuxuuna bixiyaa 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.

- RAM: 12 TiB;
- Tirada mashiinnada farsamada gacanta ee la martigeliyay: 250;
- 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.

Doorashooyinka hirgelinta
Sidaan horayba u soo sheegnay, oVirt waxa laga dhisay laba walxood oo asaasi ah: ovirt-engine (maamulka) iyo ovirt-host (hypervisor).
Matoorka waxaa lagu martigelin karaa meel ka baxsan goobta lafteeda (Maareeye gooni-gooni ah - tani waxay noqon kartaa VM ku shaqeeya goob kale ama hypervisor gaar ah, ama xitaa mashiinka jireed) ama goobta lafteeda (mashiin iskiis u maamula, oo la mid ah habka VCSA ee 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.
Jaantuska 4 - qaab dhismeedka caadiga ah.
Jaantuska 5 - Nashqada Injineerka oo iskii u martigeliyay.
Naftayda, waxaan doortay maamulaha goonida ah iyo xulashada EL Hosts:
- Maamulaha goonida ah ayaa xoogaa u fudud in uu wax ka qabto arrimaha bilowga ah, ma jiro digaag iyo dhibaato ukun (sida VCSA-ma daabici kartid ilaa ugu yaraan hal qof oo martigeliyaha ah uu si buuxda u korayo), laakiin waxay soo bandhigaysaa ku tiirsanaanta nidaam kale *;
- EL Host wuxuu bixiyaa awooda buuxda ee OS, kaas oo faa'iido u leh la socodka dibadda, khaladka, cilad-saarka, iwm.
* Si kastaba ha ahaatee, tan looma baahnayn inta lagu guda jiro dhammaan muddada hawlgalka, xitaa ka dib markii korontadu xumaatay.
Laakiin aynu hoos u dhaadhacno ganacsiga!
Tijaabadaan, waxaan ku haynaa dhowr baalle oo ProLiant BL460c G7 ah oo wata Xeon® CPU. Waxaan u isticmaali doonaa si aan ugu celcelino habka rakibidda.
Waxaan siin doonaa noodhka magacyada ovirt.lab.example.com, kvm01.lab.example.com iyo kvm02.lab.example.com.
Aynu si toos ah ugu dhaqaaqno .
