20-Port Ethernet L3 Switch, 4 x 10Gb SFP+, 20 x 40Gb QSFP+ kanye 4 x 100Gb QSFP28

I-20-Port Ethernet L3 Switch, 4 x 10Gb SFP+, ne-20 x 40Gb QSFP+ kanye neswishi engu-4 x 100Gb QSFP28 iyidivayisi yenethiwekhi esebenza kahle kakhulu elungele ukwakhiwa kwenethiwekhi yamabhizinisi amakhulu nezikhungo zedatha. Izinhlobo eziningi zezimbobo zokushintsha kanye nezimiso eziyisisekelo ezisekelwayo ziyenza ilungele ukwakha izakhiwo zenethiwekhi ezisebenza kahle, ezinzile futhi eziqinile. Okokuqala, ukushintshwa kufakwe amachweba we-20 10Gb SFP +, anamakhono okudlulisa idatha ngesivinini esiphezulu futhi afanele ukuxhuma amaseva asebenza kahle, amadivaysi okugcina kanye namanye amadivaysi enethiwekhi ukuze ahlangabezane nezidingo zokushintshaniswa kwedatha enkulu. Ngesikhathi esifanayo, izimbobo ezine ze-10Gb SFP + zinikeza indlela yokuxhuma inethiwekhi eguquguqukayo futhi isekela ukufinyelela kwamadivaysi enethiwekhi ahlukene.

Ngaphezu kwalokho, ukushintshwa kufakwe amachweba angu-20 40Gb QSFP+ ukuze kusekelwe ukudluliswa kwedatha yomkhawulokudonsa kanye nezidingo zokuxhuma. Lawa machweba anesivinini esikhulu abalulekile ekwakheni ukuxhumana okuminyanisa kakhulu ezikhungweni zedatha ezinkulu kanye namanethiwekhi ebhizinisi ukuze kuhlangatshezwane nesidingo esikhulayo sokushintshisana kwedatha nokuthuthukisa ukusetshenziswa nokusebenza kwenethiwekhi. Ngesikhathi esifanayo, izimbobo ezine ze-100Gb QSFP28 zisebenza njengezinga eliphezulu lokuxhumanisa isivinini esikhulu, ngokuqhubekayo nokuhlinzeka ngomkhawulokudonsa wedatha omkhulu kanye nekhono lokudlulisa idatha ngesivinini esiphezulu. Izikebhe ezinjalo ezinesivinini esikhulu zingasetshenziswa ukuxhuma amakhompiyutha amakhulu, izinkundla zokuhlaziya idatha nezinye izimo zohlelo lokusebenza ezinezidingo zomkhawulokudonsa eziphakeme kakhulu, okuhlinzeka ngokuguquguquka okukhulu kanye nokulinganisa kwesakhiwo senethiwekhi. Ngokungeziwe ekuxhumekeni kwesivinini esikhulu, iswishi iphinde isekele izivumelwano ezibalulekile nemisebenzi efana ne-MPLS (Multiprotocol Label Switching) kanye ne-MLAG (Multi-Chassis Link Aggregation).

Iphrothokholi ye-MPLS inezinzuzo zomzila ophumelelayo, ubunjiniyela bethrafikhi, ikhwalithi yesevisi kanye nenethiwekhi yangasese ebonakalayo, engathuthukisa ukusebenza kanye nokuqina kwenethiwekhi. Ukusekela i-MLAG kusho ukuthi iswishi ingafinyelela ukuhlanganiswa kwembobo kanye nokuphinda isetshenziswe kuwo wonke amaswishi amaningi, ithuthukise ukutholakala kwenethiwekhi nokwethembeka. Ngaphezu kwalokho, ukushintshwa kubuye kube nemisebenzi yokuphatha ethuthukisiwe nemisebenzi yokuphepha, futhi isebenzisa i-chip yokushintsha esebenza kahle ukuze kuzuzwe ukucutshungulwa kwedatha ye-line-speed kanye nokuxhumeka kwenethiwekhi okuphansi. Lokhu kulungele izikhungo zedatha ezinkulu kanye namanethiwekhi ebhizinisi, okuqinisekisa ukusebenza okuphezulu, ukuzinza nokuthembeka kwenethiwekhi. Sekukonke, i-20-Port Ethernet L3 Switch, 4 x 10Gb SFP+, ne-20 x 40Gb QSFP+ kanye ne-4 x 100Gb QSFP28 switch iyiswishi esebenza kahle kakhulu eyenzelwe amabhizinisi amakhulu nezikhungo zedatha ngokuhlinzeka ngezinhlobonhlobo zamachweba anesivinini esiphezulu nokusekelwa. ukuze izivumelwano ezibalulekile zenethiwekhi zihlangabezane nezidingo zokusebenza okuphezulu, ukuxhumana okuvumelana nezimo nokwethembeka kumanethiwekhi esimanje. Ukushintsha kuzoba yingxenye ebalulekile ekwakheni ingqalasizinda yenethiwekhi ethuthukile, esebenza kahle futhi enokwethenjelwa kakhulu.
