Ama-PDU anemitha aqapha futhi abonise ukusetshenziswa kwamandla, okuvumela abasebenzisi ukuthi balandelele ukusetshenziswa kwamandla ngempumelelo. Ngokuphambene, ama-PDU angalinganisiwe asabalalisa amandla ngaphandle kwamakhono okuqapha. Ukuqonda lo mehluko kubalulekile ekuthuthukiseni ukuphathwa kwamandla ezikhungweni zedatha nokuqinisekisa ukusebenza kahle kwamadivayisi afana ne-Metered Rack Mount PDU.
Okuthathwayo Okubalulekile
- Ama-PDU anemitha ahlinzeka ngokuqapha kwesikhathi sangempelaukusetshenziswa kwamandla, ukusiza abasebenzisi ukuphatha ukusetshenziswa kwamandla ngempumelelo.
- Ama-PDU angalinganisiwe anikezela ngesixazululo esingabizi kakhulu sokusabalalisa amandla ayisisekelo ngaphandle kwamakhono okuqapha.
- Ukukhetha i-PDU efanelekuncike ezidingweni zakho zokusebenza, ibhajethi, kanye nokuthi udinga ukuqapha amandla.
Incazelo ye-Metered PDU
A Imitha ye-PDU(Iyunithi Yokusabalalisa Amandla) iyidivayisi ebalulekile ezikhungweni zedatha nasezindaweni ze-IT. Ayisabalalisi amandla kagesi kuphela kumadivayisi amaningi kodwa futhi iqapha futhi ibonise ukusetshenziswa kwamandla ngesikhathi sangempela. Lokhu kusebenza okumbaxambili kuthuthukisa ukwethembeka nokusebenza kahle kokuphathwa kwamandla.
Izici ze-Metered Rack Mount PDU
I-Metered Rack Mount PDUs iza ifakwe ezininganaizici ezibalulekileeziwahlukanisa kuma-PDU ajwayelekile. Lezi zici zifaka:
- Isibonisi Sedijithali: Isibonisi sedijithali esakhelwe ngaphakathi sibonisa idatha yesikhathi sangempela mayelana nokusetshenziswa kwamandla kagesi.
- Ukulayisha Ukulinganisa: Ama-PDU anemitha asiza ukulinganisa imithwalo, avimbele izinkinga zomthamo oweqile ezingaholela ekuhlulekeni kwemishini.
- Umsebenzi wokulinganisa: Baqapha ukusetshenziswa kwamadivayisi axhunyiwe kumasokhethi ngamanye, banikeze imininingwane enemininingwane ekusetshenzisweni kwamandla.
- Ukufinyelela Okukude: Amanye amamodeli avumela abasebenzisi ukuthi bafinyelele idatha elinganisiwe bekude, okusiza ukuphathwa okungcono kwamandla.
- Ukukala Ukuphepha: Lawa mayunithi akala amandla asalayo ngokuphepha kokusebenza futhi angasetha amanani omkhawulo ezixwayiso.
Nasi isifinyezo semininingwane yobuchwepheshe evame ukutholakala kuma-PDU we-metered rack mount:
| Ukucaciswa | Incazelo |
|---|---|
| Amandla Wokufaka | Ifinyelela ku-67kVA |
| Faka ama-Currents | 12A kuya ku-100A ngomugqa ngamunye |
| Ama-Voltages wokufaka | Izinketho ezihlukahlukene kusukela ku-100V kuya ku-480V |
| Ukunemba Kwemitha | ±0.5% |
| Ukuminyana kwe-Outlet Receptacle | Kufika kuma-outlet angama-54 |
| Izinga Lokushisa Le-Ambient Elikhulu | 60°C (140°F) |
| Umswakama Ohlobene | 5-90% RH (iyasebenza) |
Ukuqapha Amakhono
Amakhono okuqapha ama-PDU anemitha abalulekile ekuphathweni kwamandla okusebenzayo. Baqoqa idatha yesikhathi sangempela kumapharamitha ahlukahlukene, okuhlanganisa:
- Okwamanje (A)
- I-Wattage (W)
- Amandla kagesi (V)
- Imvamisa (Hz)
Le datha ivumela abasebenzisi ukuthi balandelele umthamo omkhulu, isici samandla, kanye nokusetshenziswa kwamandla sekukonke ngokuhamba kwesikhathi. Abasebenzisi bangafinyelela lolu lwazi ngezindlela zokuqapha zendawo, njengezinkomba ze-LED nezibonisi ze-LCD. Ukwengeza, ama-PDU amaningi anemitha anikeza ukuqapha okukude ngokusebenzisa izixhumanisi zewebhu kanye nesofthiwe yokuphatha amandla, okuvumela ukuphathwa kwesikhungo sedatha okuphumelelayo.
Incazelo ye-PDU engalinganisiwe
I-PDU engalinganisiwe (Iyunithi Yokusabalalisa Amandla) isebenza njengesixazululo esiqondile sokusabalalisa amandla ezikhungweni zedatha nasezindaweni ze-IT. Ngokungafani nama-PDU anemitha, amayunithi angalinganisiwe agxila kuphela ekusabalaliseni amandla kagesi ngaphandle kokunikeza noma yimaphi amakhono okuqapha. Lokhu kulula kubenza babe ukukhetha okudumile kwezinhlelo zokusebenza ezithile.
Izici ze-PDU engalinganisiwe
Ama-PDU angalinganisiwe afika nezici ezimbalwa ezibalulekile ezihlangabezana nezidingo eziyisisekelo zokusabalalisa amandla. Lezi zici zifaka:
- Ukusabalalisa Amandla Okuyisisekelo: Basabalalisa amandla kumadivayisi amaningi ngaphandle kwanoma yimiphi imisebenzi yokuqapha.
- Izinhlobonhlobo Zokucushwa: Ama-PDU angalinganisiwe ayatholakala ekucushweni okuhlukahlukene, okuhlanganisa imiklamo evundlile neqondile, ukuze ilingane ukusetha okuhlukile kwama-rack.
- Isixazululo Esisebenza Ngezindleko: Lawa mayunithi ngokuvamile abiza ngaphansi kozakwabo abanamamitha, okuwenza abe inketho ekhangayo ezinhlanganweni ezikhathalela ibhajethi.
- I-Robust Design: Ama-PDU angalinganisiwe ngokuvamile afaka ukwakhiwa okuqinile, okuqinisekisa ukusebenza okuthembekile ezindaweni ezidinga kakhulu.
Ukuntuleka Kwamakhono Okuqapha
Ukungabikho kwamandla okuqapha kuma-PDU angalinganisiwe kungaba nomthelela omkhulu ekuphathweni kwamandla ezikhungweni zedatha. Ngaphandle kwedatha yesikhathi sangempela, abasebenzisi babhekana nezinselele ezimbalwa:
- Ama-PDU angagadiwe angaholela ekushiseni ngokweqile kwemishini kanye nokungasebenzi kahle kwe-circuit breaker.
- Ukuntuleka kokuqapha kwenza kube nzima ukuhlonzwa nokuxazululwa kwezindaba zekhwalithi yamandla.
- Izikhungo zedatha zingase zibe nesikhathi esibizayo sokungasebenzi ngenxa yengqalasizinda yamandla engazinzile.
Lezi zici zigqamisa ukubaluleka kokucabangela izidingo zokuqapha lapho kukhethwa i-PDU. Ngenkathiama-PDU angalinganisiwezinikeza isixazululo esilula nesingabizi kakhulu, zingase zinganikezi ukugada okudingekayo kokuphathwa kwamandla okuhle kakhulu ezindaweni eziyinkimbinkimbi.
Ukuqhathaniswa kwama-PDU Angamamitha Nangalinganisiwe
Izinzuzo zama-Metered PDUs
Ama-PDU anemitha anikeza izinzuzo ezibalulekile ezimbalwa ezithuthukisayoukuphathwa kwamandla ezikhungweni zedatha. Lezi zinzuzo zihlanganisa:
| Inzuzo | Incazelo |
|---|---|
| Ukusebenza Kwamandla | Ama-PDU anemitha athuthukisa ukusebenza kahle kwamandla ngokunikeza izilinganiso ezinembile zokusetshenziswa kwamandla. Lokhu kuvumela ukuqapha okuphumelelayo nokuphathwa kokusetshenziswa kwamandla. |
| Ukuphathwa Kwezindleko | Ivumela ukwabiwa okunembile kwezindleko zamandla ezindaweni okwabelwana ngazo, ivimbela ukugcwala kwesekethe futhi ithuthukise ukusatshalaliswa kwamandla. Lokhu ekugcineni kunciphisa izindleko zokusebenza. |
| Izinhlelo zokusebenza | Okuvame ukusetshenziswa ezikhungweni zedatha namagumbi eseva, ama-PDU anemitha asekela ukuhlelwa kwamandla nokwandisa isikhathi sokuphumula, ukuqinisekisa ukwethembeka ezindaweni ezibucayi zemishini. |
Izinhlangano zingaphinda zihlonze amadivayisi asebenzisa amandla kakhulu ngedatha enembile ngokusetshenziswa kwamandla. Ngokuthuthukisa lawa madivayisi, anganciphisa ukusetshenziswa kwamandla okungadingekile, okuholela ekwehliseni izikweletu zezinsiza. Ucwaningo olwenziwa yi-Bitkom lubonisa ukuthi ukusebenza kahle kwamandla kungathuthuka ngo-30% ngokusebenza kokulinganisa kwama-PDU.
Izinzuzo zama-PDU angalinganisiwe
Ama-PDU angalinganisiwe ahlinzeka ngesixazululo esiqondile sokusabalalisa amandla. Izinzuzo zabo eziyinhloko zihlanganisa:
- Ubulula: Ama-PDU angalinganisiwe agxila kuphela ekusabalaliseni amandla, awenze kube lula ukuwafaka nokuwasebenzisa.
- Izindleko-Ngempumelelo: Lawa mayunithi ngokuvamile abiza ngaphansi kwezinketho zamamitha, okuwenza afanelekele izinhlangano ezikhathalela ibhajethi.
- I-Robust Design: Ama-PDU angalinganisiwe ngokuvamile afaka ukwakhiwa okuqinile, okuqinisekisa ukusebenza okuthembekile ezindaweni ezidinga kakhulu.
Sebenzisa Amakesi Ohlotsheni ngalunye
Ama-PDU anemitha alungele izindawo lapho ukuqapha ukusetshenziswa kwamandla kubaluleke kakhulu. Zifanele izikhungo zedatha, amagumbi amaseva, kanye nezinhlelo zokusebenza ezibaluleke kakhulu kumgomo. Ngokuphambene, ama-PDU angalinganisiwe asebenza kahle ekusetheni okungaxaki kangako, njengamahhovisi amancane noma izindawo lapho ukusetshenziswa kwamandla kungadingi ukuqapha eduze.
Ama-PDU anemitha anikezela ngokuqapha kwesikhathi sangempela kanye nokuphathwa kwamandla, okuwenza alungele izindawo eziyinkimbinkimbi. Ama-PDU angalinganisiwe ahlinzeka ngesixazululo esingabizi kakhulu sokusetha okulula. Lapho ukhetha phakathi kwazo, cabangela izici ezifana nezidingo zokusebenza, ibhajethi, nemigomo yokuthobela amandla:
- Izidingo zamandla: Qonda ingqikithi yezidingo zamandla emishini yakho.
- Izici Ezithuthukile: Cabangela izinketho ezifana nokuqapha kwesikhathi sangempela nokuphatha kude.
Ukukhetha i-PDU efanele kuqinisekisa ukusatshalaliswa kwamandla okusebenzayo futhi kunciphisa izingozi ezihlobene nezinkinga zekhwalithi yamandla.
