Ko te LAN me te SAN he tohu mō te Whatunga Rohe ā-Rohe me te Whatunga Rohe Rokiroki, ā, koinei ngā pūnaha whatunga rokiroki matua e whakamahia whānuitia ana i ēnei rā.
Ko te LAN he kohinga rorohiko me ngā taputapu tāpiri e tohatoha ana i tētahi hononga whakawhitiwhiti waea, ahokore rānei ki ngā tūmau kei ngā rohe matawhenua rerekē. Ko te SAN i roto i tētahi whatunga, i tētahi atu ringa, e whakarato ana i te hononga tere-teitei, ā, kua hangaia mō ngā whatunga tūmataiti, e āhei ai te hononga maeneene o ngā tūmau maha me ngā momo taputapu rokiroki tiritahi.
Nō reira, ko ngā wāhanga matua e rua e whakamahia ana i roto i te whatunga rorohiko ko ngā pana LAN me ngā pana SAN. Ahakoa he hongere whakawhitiwhiti raraunga ngā pana LAN me ngā pana SAN, he rerekētanga kei a rāua, nō reira me titiro tata atu tātou ki raro.
1 He aha te whakawhiti LAN?
Ko te whakawhiti LAN he tikanga whakawhiti pākete e whakamahia ana mō te tuku pākete i waenga i ngā rorohiko i runga i te LAN i roto i te whatunga rohe. He mea nui tēnei tikanga i roto i te hoahoa whatunga, ā, ka taea te whakapai ake i te pai o te LAN me te whakaiti i ngā here o te whānui o te hononga. E whā ngā momo whakawhiti LAN:
MLS whakawhiti paparanga maha;
Whakawhitinga Papa 4;
Whakawhitinga Papa 3;
Whakawhitinga Papa 2.
Me pēhea te mahi a te pana LAN?
He pana Ethernet te pana LAN e mahi ana i runga i te kawa IP, ā, e whakarato ana i te hononga ngāwari i waenga i ngā kaituku me ngā kaiwhiwhi mā roto i tētahi whatunga tauranga me ngā hononga honohono. Mā tēnei whakaritenga ka taea e te tini o ngā kaiwhakamahi mutunga te tohatoha rauemi whatunga. Ka mahi ngā pana LAN hei pana mōkihi, ā, ka taea te whakahaere i ngā tuku raraunga maha i te wā kotahi. Ka mahia tēnei mā te tirotiro i te wāhitau ūnga o ia anga raraunga, ka tukuna tonutia ki tētahi tauranga motuhake e hono ana ki te pūrere kaiwhiwhi e whakaarohia ana.
Ko te mahi matua a te pana LAN he whakatutuki i ngā hiahia o tētahi rōpū kaiwhakamahi kia taea ai e rātou te uru atu ki ngā rauemi tiritahi me te whakawhitiwhiti kōrero pai. Mā te whakamahi i ngā āheinga o ngā pana LAN, ka taea te whakanoho i tētahi wāhanga nui o te waka whatunga ki ngā wāhanga LAN kiato. Mā tēnei wehewehenga ka whakaitihia te noho puku o te LAN, ka maeneene ake te whakawhiti raraunga me te whakahaere whatunga.
2 He aha te whakawhiti SAN?
Ko te whakawhiti SAN Whatunga Rohe Rokiroki he tikanga motuhake mō te waihanga hononga i waenga i ngā tūmau me ngā puna rokiroki tiritahi hei whakahaere i te whakawhiti raraunga e pā ana ki te rokiroki.
Mā ngā pana SAN, ka taea te hanga whatunga rokiroki nui, tere-teitei e hono ana i ngā tūmau maha me te uru atu ki ngā raraunga nui, e tae atu ana ki ngā petabyte. I roto i tā rātou mahi taketake, ka whakarite pai ngā pana SAN i te haere i waenga i ngā tūmau me ngā taputapu rokiroki mā te tirotiro i ngā mōkihi me te tuku i a rātou ki ngā pito mutunga kua whakaritea. I roto i te wā, kua whanake ngā pana rokiroki rohe whatunga ki te whakauru i ngā āhuatanga matatau pēnei i te taurite ara, te tātaritanga whatunga, me te pūoko aunoa i te whānui.
Me pēhea te mahi a ngā pana o te Fibre Channel?
He wāhanga matua te pana Fibre Channel i roto i te whatunga rohe rokiroki SAN e āwhina ana ki te whakawhiti raraunga i waenga i ngā tūmau me ngā taputapu rokiroki. Ka mahi te pana mā te waihanga i tētahi whatunga tūmataiti tere-teitei kua hangaia mō te rokiroki me te tiki raraunga.
I tōna pūtake, ka whakawhirinaki te pana Fibre Channel ki ngā taputapu me ngā pūmanawa motuhake hei whakahaere me te ārahi i te haere o ngā raraunga. Ka whakamahia e ia te kawa Fibre Channel, he kawa whakawhitiwhiti kōrero pakari me te pono i hangaia mō ngā taiao SAN. I te mea ka tukuna ngā raraunga mai i te tūmau ki te pūrere rokiroki, ā, i te ritenga kē, ka whakauruhia ki roto i ngā anga Fibre Channel, hei whakarite i te pono o ngā raraunga me te tuku tere-teitei.
Ka mahi te pana SAN hei pirihimana huarahi, ā, ka whakatau i te ara pai rawa atu mō ngā raraunga ki te haere mā roto i te SAN. Ka tirotirohia ngā wāhitau pūtake me ngā wāhitau ūnga i roto i ngā anga Fibre Channel kia pai ai te ara o ngā mōkihi. Ka whakaitihia e tēnei ara atamai te whakaroa me te whakakīkī, kia tere ai, kia pono ai hoki te taenga atu o ngā raraunga ki tōna ūnga.
Ko te tikanga, ka whakarite ngā pana Fibre Channel i te rere o ngā raraunga i roto i te SAN, ka arotau i te mahi me te pono i roto i ngā taiao e nui ana te raraunga.
3 He aha ngā rerekētanga o ēnei?
Ko te whakataurite i te pana LAN ki te pana SAN ka taea hoki te whakaaro he whakataurite i te pana SAN ki te pana whatunga, i te pana Fibre Channel rānei ki te pana Ethernet. Me titiro tātou ki ngā rerekētanga matua i waenga i ngā pana LAN me ngā pana SAN.
Ngā Rerekētanga Taupānga
I hangaia tuatahitia ngā pana LAN mō ngā whatunga token ring me te FDDI, ā, i muri mai ka whakakapia e te Ethernet. He mea nui te mahi a ngā pana LAN ki te whakapai ake i te whai huatanga whānui o ngā LAN me te whakaoti rapanga whānui o te whānui. Ka taea e ngā LAN te hono pai i ngā momo taputapu pēnei i ngā tūmau kōnae, ngā pūreretā, ngā huinga rokiroki, ngā papamahi, me ētahi atu, ā, ka taea e ngā pana LAN te whakahaere pai i te rere o ngā raraunga i waenga i ēnei pūwāhi mutunga rerekē.
Ā, kua hangaia te pana SAN mō ngā whatunga mahi-teitei kia iti ai te whakaroa me te kore e ngaro te whakawhiti raraunga. He mea āta hangaia kia pai ai te whakahaere i ngā kawenga tauwhitinga taumaha, inā koa i roto i ngā whatunga Fibre Channel mahi-teitei. Ahakoa he Ethernet, he Fibre Channel rānei, kua whakatapua, kua arotauhia hoki ngā pana whatunga rohe rokiroki hei whakahaere i te haere o te rokiroki.
Ngā Rerekētanga Mahi
I te nuinga o te wā, ka whakamahia e ngā pana LAN ngā atanga parahi me te muka, ā, ka mahi i runga i ngā whatunga Ethernet e hangai ana ki te IP. Ka tukuna e te pana LAN Papa 2 ngā painga o te whakawhiti raraunga tere me te iti o te whakaroa.
He tino pai ngā āhuatanga pēnei i te VoIP, te QoS me te pūrongo whānui. He rite ngā āhuatanga o ngā pana LAN Papa 3 ki ngā pouara. Mō te Pana LAN Papa 4, he putanga matatau o te Pana LAN Papa 3 e tuku ana i ngā tono tāpiri pēnei i te Telnet me te FTP. Hei tāpiri, ka tautoko te Pana LAN i ngā kawa tae atu ki te SNMP, DHCP, Apple Talk, TCP/IP, me te IPX. I te katoa, he otinga whatunga utu-whai hua, ngāwari-ki-te-whakatakoto te Pana LAN, he pai mō ngā hiahia whatunga hinonga me ngā hiahia whatunga matatau.
Ka hangaia ngā pana SAN i runga i te turanga o ngā whatunga rokiroki iSCSI, e whakauru ana i ngā hangarau Fibre Channel me te iSCSI. Ko te āhuatanga nui ko te kaha rokiroki pai ake o ngā pana SAN i ngā pana LAN. Ka taea hoki e ngā pana Fibre Channel te noho hei pana Ethernet.
Ko te mea tino pai, ko te pana SAN e hangai ana ki te Ethernet ka whakatapua ki te whakahaere i te waka rokiroki i roto i te whatunga rohe rokiroki IP, kia pai ai te mahi. Waihoki, mā te hono i ngā pana SAN, ka taea te hanga i tētahi whatunga SAN whānui hei hono i ngā tūmau me ngā tauranga rokiroki maha.
4 Me pēhea te whiriwhiri i te pana tika?
Ina whakaarohia te LAN me te SAN, he mea nui te whiriwhiri i te pana LAN, i te pana SAN rānei. Mena kei roto i ō hiahia ngā kawa tiritiri kōnae pēnei i te IPX, i te AppleTalk rānei, ko te pana LAN e hangai ana ki te IP te whiringa pai rawa atu mō te pūrere rokiroki. I tetahi atu taha, ki te hiahia koe ki te pana hei tautoko i te rokiroki e hangai ana ki te Fibre Channel, ka tūtohutia he pana rokiroki rohe whatunga.
Mā ngā pana LAN ka taea te whakahaere i te whakawhitiwhiti kōrero i roto i te LAN mā te hono i ngā taputapu i roto i te whatunga kotahi.
Ko ngā pana Fibre Channel, i tētahi atu taha, e whakamahia ana hei hono i ngā taputapu rokiroki ki ngā tūmau kia pai ai te rokiroki me te tiki raraunga. He rerekē te utu, te tauine, te āhua o te rorohiko, te haumarutanga, me te kaha rokiroki o ēnei pana. Ko te kōwhiringa i waenga i a rātou ka whakawhirinaki ki ngā whakaritenga whakamahinga motuhake.
He iti te utu o ngā pana LAN, ā, he ngāwari hoki te whirihora, engari he nui te utu o ngā pana SAN, ā, he uaua ake ngā whirihoranga e hiahiatia ana.
I te poto, he momo whakawhiti whatunga rerekē ngā pana LAN me ngā pana SAN, he tūranga motuhake tā ia pana i roto i te whatunga.
