Ka tonohia nga kaipanui kia waia ki nga maataapono mo te hanga i te hanga he-whakaaro mo te hinonga iti i roto i te pokapū raraunga kotahi, ka korerohia i roto i nga waahanga poto o nga tuhinga.
Kupu whakataki
Na pokapū raraunga (Pokapū Tukatuka Raraunga) ka taea te mohio ko:
- ake whatanga i roto i tona ake "ruma tūmau" i runga i te rohe o te hinonga, e tutuki nga whakaritenga iti mo te whakarato hiko me te taputapu whakamahana, me te whai waahi Ipurangi ma nga kaiwhakarato motuhake e rua;
- he whatanga reti me ona ake taputapu, kei roto i te pokapū raraunga tuuturu - te mea e kiia ana. he kohinga Tier III, IV ranei e whakamana ana i te mana pono, te whakamatao me te kore e uru ki te Ipurangi;
- tino riihi taputapu i roto i te Tier III ranei IV pokapū raraunga.
Ko tehea waahanga noho hei whiriwhiri - i ia keehi, he mea takitahi nga mea katoa, me te nuinga o te waa ka whakawhirinaki ki etahi take matua:
- he aha te take e hiahia ai te hinonga ki tana ake hanganga IT;
- he aha te hiahia o te hinonga mai i te hanganga IT (te pono, te tauine, te whakahaere, me etahi atu);
- te nui o te haumi tuatahi i roto i nga hanganga IT, me te ahua o nga utu mo taua mea - te whakapaipai (ko te tikanga ko te hoko i a koe ake taputapu), te whakahaere ranei (he mea reti nga taputapu);
- te pae whakamahere o te hinonga ake.
Ka taea e koe te tuhi maha mo nga take e awe ana i te whakatau a tetahi hinonga ki te hanga me te whakamahi i ona hanganga IT, engari ko ta matou whainga ko te whakaatu i roto i nga mahi me pehea te hanga i tenei tino hanganga kia pai ai te he ka taea tonu e koe te penapena - whakaitihia te utu mo te hoko rorohiko arumoni, me karo rawa ranei.
Ka rite ki nga mahi roa e whakaatu ana, kaore e pai ki te penapena i runga i te rino, na te mea ka rua nga utu a te tangata kino, me te nui noa atu. Engari ano - he taputapu pai, he taunakitanga noa tenei, a, i te mutunga he aha te mea hei hoko me te nui o te whakawhirinaki ki nga kaha o te hinonga, me te "apo" o tana whakahaere. I tua atu, ko te kupu "aroha" me maarama i roto i te tikanga pai o te kupu, na te mea he pai ake te haumi ki nga taputapu i te waahi tuatahi, kia kore ai koe e raru nui me tana tautoko me te taapiri, na te mea i te tuatahi he he. Ko te whakamahere me te nui o te penapena moni ka nui ake nga utu i te wa e timata ana tetahi kaupapa.
Na, ko nga raraunga tuatahi mo te kaupapa:
- he hinonga kua whakatau ki te hanga i tana ake tomokanga tukutuku me te kawe i ana mahi ki te Ipurangi;
- i whakatau te kamupene ki te riihi i tetahi whatanga ki te whakauru i ana taputapu ki roto i te pokapū raraunga pai kua whakamanahia i runga i te paerewa Tier III;
- I whakatau te kamupene kia kaua e penapena nui i runga i nga taputapu, na reira i hokona nga taputapu e whai ake nei me nga whakamanatanga roa me te tautoko:

Wāhanga 1. Te Whakareri ki te Hoatu i te OVirt 4.3 Cluster
Tatūnga kaihautū taketake
Ko te whakauru me te whirihora i te OS te taahiraa ngawari. He maha nga tuhinga mo te whakauru tika me te whirihora i te OS, na reira kaore he tikanga ki te ngana ki te whakaputa i tetahi mea motuhake mo tenei.
Na, e rua a matou nga kaihautu Dell PowerEdge R640 e hiahia ana matou ki te whakauru i te OS me te mahi i nga tautuhinga tuatahi kia taea ai te whakamahi hei hypervisors ki te whakahaere miihini mariko i roto i te roopu oVirt 4.3.
I te mea e whakamahere ana matou ki te whakamahi i te rorohiko kore-arumoni kore utu oVirt, i kowhiria e matou te OS mo te tuku ope. CentOS 7.7, ahakoa ka taea te whakauru i etahi atu punaha whakahaere ki nga kaihautu mo oVirt:
- he hanga motuhake i runga i te RHEL, ko te mea e kiia ana. ;
- OS Oracle Linux Raumati 2019 mo te pupuri i te oVirt ki runga.
I mua i te whakauru i te OS, ka tūtohuhia:
- whirihora i te atanga whatunga iDRAC i runga i nga ope e rua;
- whakahōu mārō mō BIOS me iDRAC ki ngā putanga hou;
- whirihora i te Kōtaha Pūnaha o te tūmau, he pai ki te aratau Mahi;
- whirihorahia te RAID mai i nga kopae a-rohe (e taunaki ana a RAID1) hei whakauru i te OS ki runga i te tūmau.
Na ka whakauruhia e matou te OS ki runga i te kōpae i hangaia i mua ma te iDRAC - he mea noa te tukanga whakauru, kaore he waa motuhake i roto. Ka taea hoki e koe te uru atu ki te papatohu tūmau ki te tiimata i te whakaurunga OS ma te iDRAC, ahakoa kaore he mea e arai i a koe ki te hono tika i te kaitirotiro, papapātuhi me te kiore ki te tūmau me te whakauru i te OS mai i te puku kohiko.
I muri i te whakauru i te OS, ka mahia e matou ona tautuhinga tuatahi:

Ma tenei ka oti te whirihoranga o te puranga whakawhiti Cisco 2960X, a ki te tika nga mahi katoa, inaianei kei a maatau te hononga whatunga o nga huānga hanganga katoa ki a raatau i te taumata L2.
Dell MD3820f tatūnga rokiroki
I mua i te tiimata ki te whirihora i te punaha rokiroki, me hono atu ki te puranga whakawhiti Cisco 2960X atanga whakahaere, tae atu ki nga kaihautu Kaihautu1 и Kaihautu2 mā FC.
Ko te kaupapa whaanui mo te hono o te punaha rokiroki ki te puranga whakawhiti i tukuna i te upoko o mua.
Ko te kaupapa mo te hono rokiroki ma te FC ki nga kaihautu me penei te ahua:
I te wa o te hononga, he mea tika ki te tuhi i nga wahitau WWPN mo nga kaihautu FC HBA e hono ana ki nga tauranga FC i runga i te punaha rokiroki - ka tika tenei mo te whirihoranga o muri mai o te kaihautu e herea ana ki nga LUN i runga i te punaha rokiroki.
I runga i te teihana mahi a te kaiwhakahaere, tango me te whakauru i te taputapu whakahaere rokiroki Dell MD3820f - Kaiwhakahaere Rokiroki Kōpae Kōpae PowerVault (MDSM).
Ka hono atu matou ki a ia ma ona wahitau IP taunoa, ka whirihora i o matou wahitau mai i VLAN17, hei whakahaere i nga kaiwhakahaere ma te TCP/IP:
Rokiroki1:
ControllerA IP - 172.20.1.13, MASK - 255.255.255.0, Gateway - 172.20.1.2
ControllerB IP - 172.20.1.14, MASK - 255.255.255.0, Gateway - 172.20.1.2I muri i te whakarite i nga wahitau, ka haere matou ki te atanga whakahaere rokiroki me te tautuhi i te kupuhipa, te whakarite i te wa, te whakahou i te firmware mo nga kaiwhakahaere me nga kōpae, mehemea e tika ana, etc.
Me pehea te mahi i tenei ka whakaahuahia i roto i rokiroki.
I muri i te hanga i nga tautuhinga i runga ake nei, me mahi noa etahi mea:
- Whirihorahia nga ID tauranga FC kaihautu - Tautuhi Tauranga Kaihautū.
- Waihangahia he roopu manaaki − roopu manaaki me te taapiri i a maatau ope Dell e rua ki a ia.
- Waihangahia he roopu kōpae me nga kōpae mariko (LUN ranei) kei roto, ka tukuna ki nga kaihautu.
- Whirihorahia te whakaaturanga o nga kopae mariko (LUN ranei) mo nga kaihautu.
Ko te taapiri i nga kaihautu hou me nga tohu tohu o nga tauranga kaihautu FC ki a raatau ka mahia ma te tahua - Nga Mahere Kaihautu -> Tautuhia -> Kaihautū…
Ka kitea nga wahitau WWPN o nga kaihautu FC HBA, hei tauira, i te iDRAC o te tūmau.
Ko te mutunga, me whiwhi tatou i tetahi mea penei i tenei pikitia:
Ko te taapiri i tetahi roopu kaihautu hou me te hono i nga kaihautu ki tera ka mahia ma te tahua - Nga Mahere Kaihautu -> Tautuhia -> Rōpū Kaihautū…
Mo nga kaihautu, tohua te momo OS - Linux (DM-MP).
I muri i te hanga i tetahi roopu manaaki, ma te ripa Ratonga Rokiroki & Tārua, hanga he roopu kōpae - Rōpū Kōpae, me te momo e pa ana ki nga whakaritenga mo te whakararu i te he, hei tauira, RAID10, kei roto ko nga kōpae mariko o te rahi e hiahiatia ana:
Ka mutu, ko te waahi whakamutunga ko te whakaaturanga o nga kopae mariko (LUN ranei) mo nga kaihautu.
Ki te mahi i tenei, ma te tahua - Nga Mahere Kaihautu -> Mahere Lun -> Tāpiri ... ka herea e matou nga kopae mariko ki nga kaihautu ma te tuku tau ki a ratou.
Me penei te ahua o nga mea katoa ki tenei whakaahua:
Koinei te waahi ka mutu taatau me te whakatakotoranga rokiroki, a ki te tika nga mahi katoa, katahi ka kite nga kaihautu i nga LUN i tukuna ki a ratou ma o ratou FC HBA.
Me akiaki te punaha ki te whakahou i nga korero mo nga puku hono:
ls -la /sys/class/scsi_host/
echo "- - -" > /sys/class/scsi_host/host[0-9]/scanKia kite tatou he aha nga taputapu e kitea ana i runga i o maatau tūmau:
