Tsim ib qho txhaum-tolerant IT infrastructure. Ntu 2. Txhim kho thiab teeb tsa oVirt 4.3 pawg

Kab lus no yog qhov txuas ntxiv ntawm qhov dhau los - "Tsim ib qho txhaum-tolerant IT infrastructure. Ntu 1 - npaj siv oVirt 4.3 pawg".

Nws yuav npog cov txheej txheem ntawm kev teeb tsa yooj yim thiab teeb tsa ntawm oVirt 4.3 pawg rau hosting muaj cov tshuab virtual, suav nrog qhov tseeb tias tag nrho cov kauj ruam ua ntej rau kev npaj cov txheej txheem tau ua tiav yav dhau los.

Taw qhia

Lub hom phiaj tseem ceeb ntawm tsab xov xwm yog muab cov lus qhia step-by-step xws li "Tom ntej no -> Yog -> Tag"yuav ua li cas qhia qee qhov nta thaum txhim kho thiab teeb tsa nws. Cov txheej txheem rau kev xa tawm koj pawg yuav tsis yog ib txwm sib luag nrog cov uas tau piav qhia hauv nws, vim yog cov yam ntxwv ntawm cov txheej txheem thiab ib puag ncig, tab sis cov ntsiab lus dav dav yuav zoo ib yam.

Los ntawm ib tug subjective taw tes ntawm view, oVirt 4.3 nws cov functionality zoo ib yam li VMware vSphere version 5.x, tab sis tau kawg nrog nws tus kheej configuration thiab ua hauj lwm nta.

Rau cov neeg nyiam, txhua qhov sib txawv ntawm RHEV (aka oVirt) thiab VMware vSphere tuaj yeem pom hauv Is Taws Nem, piv txwv. no, tab sis kuv tseem yuav qee zaus nco ntsoov qee qhov ntawm lawv qhov sib txawv lossis qhov zoo sib xws nrog ib leeg raws li tsab xov xwm nthuav dav.

Cais, kuv xav piv me ntsis ua hauj lwm nrog tes hauj lwm rau virtual tshuab. oVirt siv txoj hauv kev zoo sib xws ntawm kev tswj hwm network rau cov tshuab virtual (tom qab no hu ua VMs), xws li hauv VMware vSphere:

• siv tus qauv Linux choj (hauv VMware - Standard vSwitch), khiav ntawm virtualization hosts;
• siv Open vSwitch (OVS) (hauv VMware - Distributed vSwitch) yog qhov hloov pauv virtual uas muaj ob lub ntsiab lus tseem ceeb: lub hauv paus OVN server thiab OVN controllers ntawm cov tswj hwm.

Nws yuav tsum raug sau tseg tias vim qhov yooj yim ntawm kev siv, tsab xov xwm yuav piav qhia txog kev teeb tsa kev sib txuas hauv oVirt rau VM siv tus qauv Linux choj, uas yog tus qauv xaiv thaum siv KVM hypervisor.

Hauv qhov no, muaj ntau txoj cai yooj yim rau kev ua haujlwm nrog lub network hauv pawg, uas yog qhov zoo tshaj plaws kom tsis txhob ua txhaum:

• Txhua qhov kev teeb tsa network ntawm cov tswv ua ntej muab lawv rau oVirt yuav tsum zoo ib yam, tshwj tsis yog qhov chaw nyob IP.
• Thaum tus tswv tsev tau raug coj mus rau hauv kev tswj hwm ntawm oVirt, nws tsis pom zoo kom hloov ib yam dab tsi manually hauv kev teeb tsa network yam tsis muaj kev ntseeg siab hauv koj qhov kev ua, txij li tus neeg sawv cev oVirt yuav tsuas yob lawv rov qab mus rau yav dhau los tom qab rov pib lub party lossis tus neeg sawv cev.
• Ntxiv lub network tshiab rau VM, nrog rau kev ua haujlwm nrog nws, yuav tsum tsuas yog ua los ntawm oVirt tswj console.

Lwm tus ceeb toom - rau ib puag ncig tseem ceeb heev (rhiab heev rau kev poob nyiaj), nws tseem yuav pom zoo kom siv cov nyiaj them yug thiab siv Red Hat Virtualization 4.3. Thaum lub sijhawm ua haujlwm ntawm oVirt pawg, qee qhov teeb meem yuav tshwm sim rau qhov uas nws raug nquahu kom tau txais kev pab tsim nyog sai li sai tau, tsis yog nrog lawv tus kheej.

Thiab thaum kawg pom zoo Ua ntej xa ib qho oVirt pawg, paub koj tus kheej nrog cov ntaub ntawv raug cai, txhawm rau kom paub txog yam tsawg kawg ntawm cov ntsiab lus thiab cov ntsiab lus, txwv tsis pub nws yuav nyuaj me ntsis los nyeem cov seem ntawm tsab xov xwm.

Yooj yim rau kev nkag siab cov kab lus thiab cov hauv paus ntsiab lus ntawm kev ua haujlwm ntawm oVirt pawg yog cov ntaub ntawv qhia no:

• oVirt Installation Guide
• oVirt Self-Hosted Engine Guide
• oVirt Administration Guide
  

Qhov ntim tsis loj heev, hauv ib teev lossis ob teev koj tuaj yeem paub cov ntsiab lus yooj yim, tab sis rau cov neeg nyiam cov ntsiab lus, nws raug nquahu kom nyeem. Cov ntaub ntawv khoom siv rau Red Hat Virtualization 4.3 - RHEV thiab oVirt yog qhov tseem ceeb tib yam.

Yog li, yog tias tag nrho cov kev teeb tsa yooj yim ntawm cov tswv, cov keyboards thiab cov tshuab khaws cia tau ua tiav, peb mus ncaj qha mus rau kev xa tawm ntawm oVirt.

Ntu 2. Txhim kho thiab teeb tsa oVirt 4.3 pawg

Rau kev yooj yim ntawm kev taw qhia, Kuv yuav sau cov ntu tseem ceeb hauv kab lus no, uas yuav tsum ua kom tiav ib qho los ntawm ib qho:

1. Txhim kho oVirt tswj server
2. Tsim ib tug tshiab data center
3. Tsim ib pawg tshiab
4. Txhim kho cov tswv tsev ntxiv hauv ib puag ncig Tus Kheej
5. Tsim ib qho chaw cia lossis chaw cia khoom
6. Tsim thiab teeb tsa network rau cov tshuab virtual
7. Tsim ib daim duab installation rau deploying lub tshuab virtual
8. Tsim lub tshuab virtual

Txhim kho oVirt tswj server

oVirt tswj server yog lub hauv paus tseem ceeb tshaj plaws hauv oVirt infrastructure, nyob rau hauv daim ntawv ntawm lub tshuab virtual, tus tswv tsev, lossis lub tshuab virtual uas tswj hwm tag nrho oVirt infrastructure.

Nws cov analogues ze ntawm lub ntiaj teb ntawm virtualization yog:

• VMware vSphere - vCenter Server
• Microsoft Hyper-V - System Center Virtual Machine Manager (VMM).

Txhawm rau nruab oVirt tswj server, peb muaj ob txoj kev xaiv:

Qhov 1
Deploying server nyob rau hauv daim ntawv ntawm ib tug tshwj xeeb VM los yog tus tswv tsev.

Qhov kev xaiv no ua haujlwm zoo heev, tab sis yog tias qhov VM ua haujlwm ntawm nws tus kheej ntawm pawg, piv txwv li. tsis tau khiav ntawm ib pawg tswj hwm raws li lub tshuab virtual niaj hnub khiav KVM.

Vim li cas ho tsis tuaj yeem siv VM rau ntawm pawg tswv?

Thaum pib ntawm cov txheej txheem ntawm kev xa tawm oVirt tswj server, peb muaj qhov teeb meem - peb yuav tsum tau nruab VM kev tswj hwm, tab sis qhov tseeb tsis muaj pawg nws tus kheej tsis tau, thiab yog li peb tuaj yeem ua dab tsi ntawm ya? Yog lawm - nruab KVM rau yav tom ntej pawg ntawm, tom qab ntawd tsim lub tshuab virtual ntawm nws, piv txwv li, nrog CentOS OS thiab xa lub cav oVirt hauv nws. Qhov no feem ntau tuaj yeem ua tiav rau cov laj thawj ntawm kev tswj hwm zoo li VM, tab sis qhov no yog lub tswv yim yuam kev, vim tias qhov no, yav tom ntej yuav muaj 100% teeb meem nrog kev tswj hwm VM:

• nws tsis tuaj yeem tsiv mus nyob rau hauv oVirt console ntawm hosts (nodes) ntawm pawg;
• thaum migrating siv KVM via virsh mus, VM no yuav tsis muaj rau kev tswj hwm los ntawm oVirt console.
• pawg hosts tsis tuaj yeem tso tawm hauv Kho hom (kev tu vaj tu tsev), yog tias koj tsiv VM no los ntawm tus tswv tsev mus rau tus tswv siv virsh mus.

Yog li ua txhua yam raws li txoj cai - siv ib lub tswv yim sib cais rau oVirt tswj server, lossis VM ywj siab khiav ntawm nws, lossis zoo dua, ua raws li kev xaiv thib ob.

Qhov 2
Txhim kho oVirt Engine Appliance ntawm pawg tswj hwm tswj hwm nws.

Nws yog qhov kev xaiv no uas yuav raug txiav txim siab ntxiv kom raug thiab tsim nyog hauv peb rooj plaub.
Cov kev cai rau cov VM zoo li no tau piav qhia hauv qab no; Kuv tsuas yog yuav ntxiv tias nws raug pom zoo kom muaj tsawg kawg yog ob lub tswv yim hauv cov txheej txheem uas tswj hwm VM tuaj yeem ua haujlwm txhawm rau ua kom nws ua txhaum. Ntawm no kuv xav ntxiv qhov ntawd, raws li kuv tau sau rau hauv cov lus hauv tsab xov xwm dhau los, kuv yeej tsis tau txais splitbrain ntawm oVirt pawg ntawm ob tus tswv, nrog lub peev xwm los khiav host-engine VMs ntawm lawv.

Txhim kho oVirt Engine Appliance ntawm thawj tus tswv ntawm pawg

Txuas mus rau official cov ntaub ntawv - oVirt Self-Hosted Engine Guide, tshooj "Deploying tus kheej-Hosted Cav siv cov kab hais kom ua»

Cov ntaub ntawv qhia txog qhov yuav tsum tau ua ua ntej uas yuav tsum tau ua ua ntej xa ib lub cav-tswj VM, thiab tseem piav qhia meej txog cov txheej txheem kev teeb tsa nws tus kheej, yog li tsis muaj qhov taw qhia me me hauv kev rov hais dua nws cov lus, yog li peb yuav tsom mus rau qee cov ntsiab lus tseem ceeb.

• Ua ntej pib ua txhua yam, nco ntsoov ua kom muaj kev txhawb nqa virtualization hauv BIOS nqis ntawm tus tswv tsev.
• Nruab lub pob rau host-engine installer ntawm tus tswv tsev:

yum -y install http://resources.ovirt.org/pub/yum-repo/ovirt-release43.rpm 
yum -y install epel-release
yum install screen ovirt-hosted-engine-setup

• Peb pib cov txheej txheem rau deploying oVirt Hosted Engine hauv qhov screen ntawm tus tswv tsev (koj tuaj yeem tawm ntawm Ctrl-A + D, kaw ntawm Ctrl-D):

screen
hosted-engine --deploy

Yog tias koj xav tau, koj tuaj yeem khiav lub installation nrog cov ntaub ntawv teb ua ntej npaj:

hosted-engine --deploy --config-append=/var/lib/ovirt-hosted-engine-setup/answers/answers-ohe.conf

• Thaum deploying hosted-engine, peb qhia tag nrho cov tsim nyog tsis:

- имя кластера
- количество vCPU и vRAM (рекомендуется 4 vCPU и 16 Гб)
- пароли
- тип хранилища для hosted engine ВМ – в нашем случае FC
- номер LUN для установки hosted engine
- где будет находиться база данных для hosted engine – рекомендую для простоты выбрать Local (это БД PostgreSQL работающая внутри этой ВМ)
и др. параметры. 

• Txhawm rau txhim kho VM muaj ntau yam nrog lub cav muaj tswv yim, peb yav dhau los tau tsim ib qho tshwj xeeb LUN ntawm lub kaw lus cia, tus lej 4 thiab 150 GB loj, uas tau nthuav tawm rau pawg tswv cuab - saib tsab xov xwm dhau los.

Yav dhau los peb kuj tau txheeb xyuas nws qhov pom ntawm cov tswv:

multipath -ll

  `- 18:0:0:4  sdj 8:144 active ready running

• Tus txheej txheem host-engine deployment nws tus kheej tsis nyuaj; thaum kawg peb yuav tsum tau txais qee yam zoo li no:

[ INFO  ] Generating answer file '/var/lib/ovirt-hosted-engine-setup/answers/answers-20191129131846.conf'
[ INFO  ] Generating answer file '/etc/ovirt-hosted-engine/answers.conf'
[ INFO  ] Stage: Pre-termination
[ INFO  ] Stage: Termination
[ INFO  ] Hosted Engine successfully deployed

Peb txheeb xyuas qhov muaj cov kev pabcuam oVirt ntawm tus tswv tsev:

Yog tias txhua yam ua tiav kom raug, tom qab kev teeb tsa tiav, siv lub web browser mus rau https://ovirt_hostname/ovirt-engine los ntawm tus thawj tswj hwm lub computer, thiab nyem [Administration Portal].

Screenshot ntawm "Administration Portal"

Los ntawm kev nkag mus rau tus ID nkag mus thiab lo lus zais (teeb tsa thaum lub sijhawm teeb tsa) rau hauv lub qhov rai zoo li hauv lub screenshot, peb tau mus rau Open Virtualization Manager tswj vaj huam sib luag, uas koj tuaj yeem ua txhua yam kev ua nrog lub virtual infrastructure:

1. ntxiv cov ntaub ntawv chaw
2. ntxiv thiab configure ib pawg
3. ntxiv thiab tswj hosts
4. ntxiv cov chaw cia lossis Storage Domains rau lub tshuab virtual disks
5. ntxiv thiab teeb tsa network rau cov tshuab virtual
6. ntxiv thiab tswj cov tshuab virtual, cov duab teeb tsa, VM templates

Tag nrho cov kev ua no yuav tau tham ntxiv, qee qhov hauv cov hlwb loj, lwm tus hauv kev nthuav dav ntxiv thiab nrog nuances.
Tab sis ua ntej kuv xav kom nyeem qhov no add-on, uas tej zaum yuav pab tau rau ntau.

Txuas ntxiv

1) Hauv paus ntsiab lus, yog tias muaj qhov xav tau, ces tsis muaj dab tsi tiv thaiv koj los ntawm kev txhim kho KVM hypervisor ntawm pawg nodes ua ntej siv pob. libvirt и qemu-kwv (los yog qemu-kvm-ev) ntawm qhov xav tau version, txawm hais tias thaum xa tawm oVirt pawg node, nws tuaj yeem ua qhov no nws tus kheej.

Tab sis yog hais tias libvirt и qemu-kwv Yog tias koj tsis tau teeb tsa qhov tseeb version, koj tuaj yeem tau txais qhov yuam kev hauv qab no thaum siv lub cav host:

error: unsupported configuration: unknown CPU feature: md-clear

Cov. yuav tsum muaj kho tshiab version libvirt nrog kev tiv thaiv los ntawm MDS, uas txhawb txoj cai no:

<feature policy='require' name='md-clear'/>

Nruab libvirt v.4.5.0-10.el7_6.12, nrog md-clear kev them nyiaj yug:

yum-config-manager --disable mirror.centos.org_centos-7_7_virt_x86_64_libvirt-latest_

yum install centos-release-qemu-ev
yum update
yum install qemu-kvm qemu-img virt-manager libvirt libvirt-python libvirt-client virt-install virt-viewer libguestfs libguestfs-tools dejavu-lgc-sans-fonts virt-top libvirt libvirt-python libvirt-client

systemctl enable libvirtd
systemctl restart libvirtd && systemctl status libvirtd

Txheeb xyuas 'md-clear' kev txhawb nqa:

virsh domcapabilities kvm | grep require
      <feature policy='require' name='ss'/>
      <feature policy='require' name='hypervisor'/>
      <feature policy='require' name='tsc_adjust'/>
      <feature policy='require' name='clflushopt'/>
      <feature policy='require' name='pku'/>
      <feature policy='require' name='md-clear'/>
      <feature policy='require' name='stibp'/>
      <feature policy='require' name='ssbd'/>
      <feature policy='require' name='invtsc'/>

Tom qab no, koj tuaj yeem txuas ntxiv txhim kho lub cav host.

2) Hauv oVirt 4.3, muaj thiab siv lub firewall firewalld yog qhov yuav tsum tau ua.

Yog hais tias thaum lub sij hawm xa tawm ntawm VM rau host-engine peb tau txais qhov yuam kev hauv qab no:

[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "firewalld is required to be enabled and active in order to correctly deploy hosted-engine. Please check, fix accordingly and re-deploy.n"}
[ ERROR ] Failed to execute stage 'Closing up': Failed executing ansible-playbook
[https://bugzilla.redhat.com/show_bug.cgi?id=1608467

Tom qab ntawd koj yuav tsum tua lwm firewall (yog tias nws siv), thiab nruab thiab khiav firewalld:

yum install firewalld
systemctl enable firewalld
systemctl start firewalld

firewall-cmd --state
firewall-cmd --get-default-zone
firewall-cmd --get-active-zones
firewall-cmd --get-zones

Tom qab ntawd, thaum txhim kho tus neeg sawv cev ovirt ntawm tus tswv tsev tshiab rau pawg, nws yuav teeb tsa cov chaw nres nkoj xav tau hauv firewalld txiav.

3) Rebooting tus tswv tsev nrog VM khiav ntawm nws nrog lub cav host.

Li qub, link 1 и link 2 tswj cov ntaub ntawv.

Tag nrho cov kev tswj hwm lub cav VM yog ua tiav tsuas yog siv cov lus txib hosted-engine ntawm tus tswv tsev uas nws khiav, txog virsh ua peb yuav tsum tsis nco qab, nrog rau qhov tseeb tias koj tuaj yeem txuas rau VM no ntawm SSH thiab khiav cov lus txib "shutdown".

Cov txheej txheem muab VM rau hauv hom kev saib xyuas:

hosted-engine --vm-shutdown

Peb reboot tus tswv tsev nrog tus neeg sawv cev ntawm lub cav thiab ua qhov peb xav tau nrog nws.

Tom qab rov pib dua, xyuas cov xwm txheej ntawm VM nrog lub cav host:

hosted-engine --vm-status

Yog tias peb VM nrog lub cav-tswj tsis pib thiab yog tias peb pom qhov yuam kev zoo sib xws hauv cov ntawv teev kev pabcuam:

4) Tshem tawm lub cav hosting thiab txhua yam cuam tshuam nrog nws.

Qee lub sij hawm nws yog ib qho tsim nyog kom tshem tawm lub cav uas tau teeb tsa yav dhau los - txuas mus rau daim ntawv qhia.

Tsuas yog khiav cov lus txib ntawm tus tswv tsev:

/usr/sbin/ovirt-hosted-engine-cleanup

Tom ntej no, peb tshem tawm cov pob khoom tsis tsim nyog, thaub qab qee qhov kev teeb tsa ua ntej no, yog tias tsim nyog:

yum autoremove ovirt* qemu* virt* libvirt* libguestfs 

Tsim ib tug tshiab data center

Cov ntaub ntawv siv - oVirt Administration Guide. Tshooj 4: Data Centers

Ua ntej cia peb txhais nws yog dab tsi data center (Kuv hais los ntawm qhov kev pab) yog ib qho chaw muaj kev sib cav uas txhais tau hais tias cov khoom siv hauv ib puag ncig tshwj xeeb.

Lub chaw khaws ntaub ntawv yog ib hom thawv uas muaj xws li:

• logical cov kev pab nyob rau hauv daim ntawv ntawm pawg thiab hosts
• pawg network kev pab nyob rau hauv daim ntawv ntawm cov logical networks thiab lub cev adapters ntawm hosts,
• khaws cia cov ntaub ntawv (rau VM disks, templates, dluab) nyob rau hauv daim ntawv ntawm cov chaw cia (Storage Domains).

Lub chaw khaws ntaub ntawv tuaj yeem suav nrog ntau pawg uas muaj ntau lub tswv yim nrog cov tshuab virtual khiav ntawm lawv, thiab nws tuaj yeem muaj ntau qhov chaw khaws cia cuam tshuam nrog nws.
Nws tuaj yeem muaj ntau lub chaw khaws ntaub ntawv; lawv ua haujlwm ntawm ib leeg. Ovirt muaj kev sib cais ntawm lub hwj chim los ntawm lub luag haujlwm, thiab koj tuaj yeem teeb tsa kev tso cai ntawm tus kheej, ob qho tib si ntawm cov ntaub ntawv chaw nruab nrab thiab ntawm nws cov ntsiab lus ntawm tus kheej.

Cov chaw khaws ntaub ntawv, lossis cov chaw khaws ntaub ntawv yog tias muaj ob peb ntawm lawv, raug tswj los ntawm ib qho kev tswj hwm console lossis portal.

Txhawm rau tsim ib lub chaw khaws ntaub ntawv, mus rau qhov chaw tswj hwm kev tswj hwm thiab tsim lub chaw khaws ntaub ntawv tshiab:
Compute >> Cov ntaub ntawv Centers >> Tshiab

Txij li thaum peb siv kev sib koom ua ke ntawm lub kaw lus cia, Hom Cia Khoom yuav tsum tau sib koom:

Screenshot ntawm Data Center Creation Wizard

Thaum txhim kho lub tshuab virtual nrog host-engine, lub chaw muab ntaub ntawv tsim los ntawm lub neej ntawd - Datacenter 1, thiab tom qab ntawd, yog tias tsim nyog, koj tuaj yeem hloov nws Hom Cia rau lwm qhov.

Tsim ib qho chaw cia lossis chaw cia khoom

Txuas mus rau cov ntaub ntawv - oVirt Administration Guide, Tshooj 8: Cia.

Cia Domain, lossis chaw cia khoom, yog qhov chaw nruab nrab rau khaws cia virtual tshuab disks, teeb tsa cov duab, qauv, thiab snapshots.

Cov chaw khaws cia tuaj yeem txuas nrog lub chaw khaws ntaub ntawv siv ntau yam kev cai, pawg thiab cov ntaub ntawv network.

oVirt muaj peb hom chaw cia:

• Cov Ntaub Ntawv - khaws tag nrho cov ntaub ntawv cuam tshuam nrog cov tshuab virtual (disks, templates). Data Domain tsis tuaj yeem sib koom ntawm cov chaw sib txawv.
• ISO Domain (tso tseg hom chaw cia khoom) - khaws cia OS installation dluab. ISO Domain tuaj yeem sib koom ntawm cov chaw sib txawv cov ntaub ntawv.
• Export Domain (tso tseg hom chaw cia khoom) - rau ib ntus cia cov duab txav ntawm cov chaw khaws ntaub ntawv.

Hauv peb cov xwm txheej tshwj xeeb, thaj chaw cia nrog cov ntaub ntawv Domain hom siv Fiber Channel raws tu qauv (FCP) los txuas rau LUNs ntawm qhov system cia.

Los ntawm qhov pom ntawm oVirt, thaum siv cov tshuab khaws cia (FC lossis iSCSI), txhua lub disk virtual, snapshot lossis template yog qhov laj thawj disk.
Cov cuab yeej thaiv tau sib sau ua ke rau hauv ib chav tsev (ntawm pawg hosts) siv Volume Group thiab tom qab ntawd muab faib siv LVM rau hauv cov khoom siv logical, uas yog siv los ua virtual disks rau VMs.

Tag nrho cov pab pawg no thiab ntau LVM ntim tuaj yeem pom ntawm pawg tswj hwm siv cov lus txib lwm и lvs ua. Lawm, tag nrho cov kev ua nrog xws li disks yuav tsum tau ua tsuas yog los ntawm oVirt console, tsuas yog nyob rau hauv tshwj xeeb mob.

Virtual disks rau VMs tuaj yeem yog ob hom - QCOW2 lossis RAW. Discs yuav yog "nyias"los yog"tuab". Snapshots yeej ib txwm tsim li "nyias".

Txoj hauv kev los tswj cov chaw khaws cia, lossis chaw cia khoom nkag los ntawm FC, yog qhov muaj txiaj ntsig zoo - rau txhua VM virtual disk muaj qhov sib cais qhov ntim uas sau tau los ntawm ib tus tswv tsev nkaus xwb. Rau FC kev sib txuas, oVirt siv qee yam xws li pawg LVM.

Cov tshuab virtual nyob ntawm tib thaj chaw khaws cia tuaj yeem txav mus los ntawm cov tswv uas koom nrog tib pawg.

Raws li peb tuaj yeem pom los ntawm cov lus piav qhia, pawg hauv oVirt, zoo li pawg hauv VMware vSphere lossis Hyper-V, qhov tseem ceeb txhais tau hais tias tib yam - nws yog kev sib koom ua ke ntawm cov tswv, nyiam zoo ib yam hauv cov khoom siv kho vajtse, thiab muaj kev cia rau virtual. tshuab disks.

Cia peb mus ncaj qha mus rau kev tsim thaj chaw cia rau cov ntaub ntawv (VM disks), vim tias tsis muaj nws lub chaw khaws ntaub ntawv yuav tsis pib.
Cia kuv ceeb toom rau koj tias tag nrho LUNs tau nthuav tawm rau pawg tswv cuab ntawm lub kaw lus cia yuav tsum pom ntawm lawv siv cov lus txib "multipath - ib".

Raws li cov ntaub ntawv, mus rau lub portal mus rau cia >> puav -> Tshiab Domain thiab ua raws li cov lus qhia los ntawm ntu "Ntxiv FCP Cia".
