Ma PDU a metered amawunika ndikuwonetsa kugwiritsa ntchito mphamvu, kulola ogwiritsa ntchito kutsata momwe amagwiritsidwira ntchito mphamvu moyenera. Mosiyana ndi izi, ma PDU osayembekezeka amagawa mphamvu popanda kuwunika. Kumvetsetsa kusiyana kumeneku ndikofunikira pakuwongolera kasamalidwe kamagetsi m'malo opangira ma data ndikuwonetsetsa kuti zida za Metered Rack Mount PDU zikuyenda bwino.
Zofunika Kwambiri
- Ma PDU a metered amapereka kuwunika kwenikwenikugwiritsa ntchito mphamvu, kuthandiza ogwiritsa ntchito kugwiritsa ntchito mphamvu moyenera.
- Ma PDU Opanda malire amapereka njira yotsika mtengo yogawa mphamvu zoyambira popanda kuwunika.
- Kusankha PDU yoyenerazimatengera zosowa zanu zogwirira ntchito, bajeti, komanso ngati mukufuna kuwunikira mphamvu.
Tanthauzo la Metered PDU
A Mtengo wa PDU(Power Distribution Unit) ndi chipangizo chofunikira m'malo opangira data komanso malo a IT. Sikuti amangogawira mphamvu zamagetsi pazida zambiri komanso amawunika ndikuwonetsa kugwiritsa ntchito mphamvu munthawi yeniyeni. Kuchita kwapawiri kumeneku kumawonjezera kudalirika komanso kuchita bwino kwa kasamalidwe ka mphamvu.
Mawonekedwe a Metered Rack Mount PDU
Ma Metered Rack Mount PDU amabwera ali ndi angapozinthu zofunikazomwe zimawasiyanitsa ndi ma PDU okhazikika. Izi zikuphatikizapo:

Kuyang'anira Maluso
Kuthekera kowunika kwa ma PDU a metered ndikofunikira pakuwongolera mphamvu kwamphamvu. Amasonkhanitsa zenizeni zenizeni pazigawo zosiyanasiyana, kuphatikiza:
- Panopa (A)
- Mphamvu (W)
- Mphamvu yamagetsi (V)
- pafupipafupi (Hz)
Deta iyi imalola ogwiritsa ntchito kutsata kuchuluka kwamphamvu, mphamvu yamagetsi, komanso kugwiritsa ntchito mphamvu kwakanthawi. Ogwiritsa ntchito amatha kupeza chidziwitsochi kudzera mu njira zowunikira m'dera lanu, monga zowonera za LED ndi zowonetsera za LCD. Kuphatikiza apo, ma PDU ambiri okhala ndi metered amapereka kuwunika kwakutali kudzera pa intaneti komanso pulogalamu yoyang'anira mphamvu, zomwe zimathandiza kasamalidwe koyenera ka data center.
Tanthauzo la Unmetered PDU
PDU yopanda malire (Gawo Logawa Mphamvu) imakhala njira yowongoka yogawa mphamvu m'malo opangira deta ndi malo a IT. Mosiyana ndi ma PDU a metered, mayunitsi osayembekezeka amayang'ana kwambiri kugawa mphamvu zamagetsi popanda kupereka mphamvu zowunikira. Kuphweka kumeneku kumawapangitsa kukhala chisankho chodziwika pamapulogalamu ena.
Mawonekedwe a Unmetered PDU
Ma PDU opanda mita amabwera ndi zinthu zingapo zofunika zomwe zimakwaniritsa zosowa zoyambira zamagetsi. Izi zikuphatikizapo:
- Basic Power Distribution: Amagawa mphamvu pazida zingapo popanda ntchito zowunikira.
- Zosiyanasiyana Zosintha: Ma PDU opanda mita akupezeka m'makonzedwe osiyanasiyana, kuphatikiza mapangidwe opingasa ndi ofukula, kuti agwirizane ndi ma rack osiyanasiyana.
- Njira Yosavuta: Mayunitsiwa nthawi zambiri amawononga ndalama zochepa poyerekeza ndi anzawo omwe ali ndi mita, zomwe zimawapangitsa kukhala njira yabwino kwa mabungwe omwe amaganizira za bajeti.
- Mapangidwe Amphamvu: Ma PDU opanda mita nthawi zambiri amakhala ndi zomangamanga zokhazikika, kuwonetsetsa kuti zikuyenda bwino m'malo ovuta.
Kupanda Kukwanitsa Kuwunika
Kusowa kwa kuthekera kowunika mu ma PDU osayembekezeka kumatha kukhudza kwambiri kasamalidwe ka magetsi m'malo opangira data. Popanda deta yeniyeni, ogwiritsa ntchito amakumana ndi zovuta zingapo:
- Ma PDU osayang'aniridwa angayambitse kutenthedwa kwa zida ndi kuwonongeka kwa ma circuit breaker.
- Kusayang'anira kumapangitsa kuti pakhale zovuta kuzindikila komanso kuthetsa vuto la mphamvu zamagetsi.
- Malo opangira data atha kukhala ndi nthawi yotsika mtengo chifukwa cha kusakhazikika kwamagetsi.
Izi zikuwonetsa kufunikira koganizira zofunikira pakusankha PDU. Pamenema PDU osadziwikakupereka njira yosavuta komanso yotsika mtengo, iwo sangapereke kuyang'anira koyenera kwa kayendetsedwe kabwino ka mphamvu m'madera ovuta kwambiri.
Kuyerekeza kwa Metered and Unmetered PDUs
Ubwino wa Metered PDUs
Ma PDU a metered amapereka zabwino zingapo zomwe zimakulitsakasamalidwe ka mphamvu m'malo opangira data. Zopindulitsa izi zikuphatikizapo:
| Ubwino | Kufotokozera |
|---|---|
| Mphamvu Mwachangu | Ma PDU a metered amawonjezera mphamvu zamagetsi popereka miyeso yolondola yakugwiritsa ntchito mphamvu. Izi zimathandiza kuti aziwunika bwino komanso kuwongolera kagwiritsidwe ntchito ka mphamvu. |
| Kuwongolera Mtengo | Amathandizira kugawa kolondola kwamitengo yamagetsi m'malo omwe amagawana nawo, kupewa kuchulukitsitsa kwadera ndikuwongolera kugawa mphamvu. Izi zimachepetsa ndalama zogwirira ntchito. |
| Mapulogalamu | Zomwe zimagwiritsidwa ntchito m'malo opangira ma data ndi zipinda za seva, ma PDU a metered amathandizira kukonza mphamvu ndikukulitsa nthawi, kuwonetsetsa kudalirika m'malo ovuta kwambiri. |
Mabungwe amathanso kuzindikira zida zogwiritsa ntchito mphamvu zambiri pogwiritsa ntchito deta yolondola pakugwiritsa ntchito mphamvu. Mwa kukhathamiritsa zida izi, zitha kuchepetsa kugwiritsa ntchito mphamvu kosafunikira, zomwe zimabweretsa kutsika kwa ndalama zothandizira. Kafukufuku wopangidwa ndi Bitkom akuwonetsa kuti mphamvu zamagetsi zimatha kuyenda bwino ndi 30% kudzera mumiyeso ya PDUs.
Ubwino wa Unmetered PDUs
Ma PDU opanda mita amapereka njira yowongoka yogawa mphamvu. Ubwino wawo waukulu ndi:
- Kuphweka: Ma PDU osayembekezeka amayang'ana kwambiri kugawa mphamvu, kuwapangitsa kukhala osavuta kukhazikitsa ndikugwiritsa ntchito.
- Mtengo-Kuchita bwino: Mayunitsiwa nthawi zambiri amawononga ndalama zochepa poyerekeza ndi zosankha zomwe zili ndi mita, zomwe zimawapangitsa kukhala oyenera m'mabungwe omwe amaganizira za bajeti.
- Mapangidwe Amphamvu: Ma PDU opanda mita nthawi zambiri amakhala ndi zomangamanga zokhazikika, kuwonetsetsa kuti zikuyenda bwino m'malo ovuta.
Gwiritsani Ntchito Milandu Pamtundu Uliwonse
Ma PDU okhala ndi metered ndi abwino m'malo omwe kuyang'anira kugwiritsa ntchito mphamvu ndikofunikira. Zimagwirizana ndi malo opangira data, zipinda za seva, ndi ntchito zofunika kwambiri. Mosiyana ndi izi, ma PDU osayengedwa amagwira ntchito bwino m'makhazikitsidwe ovuta kwambiri, monga maofesi ang'onoang'ono kapena malo omwe kugwiritsa ntchito magetsi sikufuna kuyang'anitsitsa.
Ma Metered PDUs amapereka kuwunika kwanthawi yeniyeni ndi kasamalidwe ka mphamvu, kuwapangitsa kukhala abwino kwa malo ovuta. Ma PDU opanda mita amapereka yankho lotsika mtengo pakukhazikitsa kosavuta. Posankha pakati pawo, ganizirani zinthu monga zosowa zogwirira ntchito, bajeti, ndi zolinga zotsata mphamvu:
- Zofunika Mphamvu: Kumvetsetsa zosowa zamphamvu zonse za zida zanu.
- Zapamwamba Mbali: Ganizirani zosankha monga kuyang'anira nthawi yeniyeni ndi kuyang'anira kutali.
Kusankha PDU yoyenera kumatsimikizira kugawa mphamvu moyenera ndikuchepetsa zoopsa zomwe zimakhudzana ndi nkhani zamphamvu zamagetsi.
FAQ
Kodi ntchito yayikulu ya PDU yoyesedwa ndi chiyani?

Ndisankhe liti PDU yopanda mita?
Sankhani aPDU yopanda malirekwa makhazikitsidwe osavuta pomwe kuyang'anira kugwiritsa ntchito mphamvu sikofunikira komanso kupulumutsa mtengo ndikofunikira.
Kodi ndingakweze kuchokera ku PDU yosadziwika kupita ku metered?
Inde, kukwezedwa kuchokera ku unmetered kupita ku PDU yokhala ndi mita ndikotheka. Onetsetsani kuti zikugwirizana ndi zomangamanga zomwe zilipo musanasinthe.
