Parizvino, maswiti mazhinji pamusika, kunyanya ma switch ekare, anongoshandisa simba rimwechete. Kana magetsi akakundikana (zvakadai sekukundikana kwesimba), chinja hachigoni kushanda zvakanaka, kana kunyange kuomesa network.Redundant magetsi ndiyo mhinduro yakanaka kune dambudziko iri. Maswichi akagadzirwa neasina simba emagetsi anogona kuvandudza zvakanyanya kugadzikana kwetiweki uye kuve nechokwadi kusakanganiswa kushanda kwemidziyo. Saka, chii chinonzi redundant magetsi uye nei switch ichifanira kutora dhizaini rekupa magetsi?

Chii chinonzi redundant power supply?

Redundant magetsi inoreva dhizaini yetiweki imwe mudziyo uchishandisa maviri kana anopfuura emagetsi emagetsi emagetsi, uye imwe neimwe magetsi inogona kuzvimiririra simba mudziyo. Panguva ino, kunyangwe magetsi akatadza, mamwe magetsi anobva atakura mutoro wemagetsi emidziyo kuti ive nechokwadi chekushanda kwakajairika kwemidziyo. Masevha kana dhisiki arrays anowanzo tora dhizaini yemagetsi akawandisa, ayo anogona kudzivirira kudzima kwemagetsi kana kumwe kutadza (senge nguva yekudzikira) yemidziyo. Ikozvino, dhizaini yemagetsi yakawandisa iri kuramba ichizivikanwa munetiweki switch uye mimwe michina nekuda kwemabhenefiti ayo akasiyana.

Mhedziso ye switch yakawandisa simba rekupa

Simba rekupa redundancy rinowanzo tora nzira dzekupa magetsi senge yakazara redundancy uye chikamu chidimbu. Full redundancy (inonziwo 1 + 1 redundancy) zvinoreva kuti switch ine ma module maviri emagetsi. Kana imwe module yemagetsi ikatadza, imwe module yemagetsi inogona kuramba ichipa simba zvakajairika pasina kukanganisa network kushanda. Partial redundancy (1+N redundancy) zvinoreva kuti "1 yekuwedzera magetsi" inopa simba kune "N" switch. Ndokumbira utarise kuti iyo yakashata yenzvimbo yepasi redundant magetsi ndeyekuti pane nguva yenguva yekuchinja kwemagetsi, ndiko kuti, iyo backup yemagetsi inoda kupa simba kune mudziyo mushure meimwe nguva yenguva, izvo zvinogona kukonzera kukanganisa network. Mufananidzo 1 unoratidza nzira dzakasiyana dzekushanda dzekuzara kwakazara uye kusarudzika.

Kazhinji, magetsi maviri emagetsi mune network switch anotora dhizaini yemagetsi isina kukwana. Ndapota cherechedza kuti mumamiriro ezvinhu akajairwa, magetsi ese ari maviri achabatidzwa uye anoshanda panguva imwe chete. Nekudaro, nekuda kwevagadziri vemidziyo vakasiyana, magetsi ekuchengetedza emamwe maswiti akazara akapihwa nevagadziri anogonawo kunge asina basa.
