Ikhebula Lokufaka Iseva le-MiniSAS HD SFF-8644 kuya ku-QSFP 40G SFF-8436
Izicelo:
Izintambo ze-MINI SAS zisetshenziswa kabanzi ekudlulisweni kwedatha yikhompyutha, idivayisi yeseva kanye nedatha.
I-Interface:
- I-MiniSAS HD SFF-8644 Ukuphela:
- I-MiniSAS HD (High Density) iyi-interface yokuxhumeka kwe-serial esheshayo, kanti i-SFF-8644 iyincazelo yayo ethile ye-interface. Lesi sixhumanisi sivame ukusetshenziswa kumaseva, amadivayisi okugcina, njll., futhi singasekela ukudluliswa kwedatha yeziteshi eziningi, sinikeze i-bandwidth yedatha ephezulu kanye nesilinganiso sokudlulisa. Inokwethenjelwa okuphezulu nokuzinza futhi ifanelekela izindawo zeseva ezinezidingo eziphezulu zokudluliswa kwedatha.
- Lesi sixhumi esibonakalayo ngokuvamile sinamaphini amaningi okudlulisa idatha, ukunikezwa kwamandla, kanye nokusebenzisana kwezimpawu zokulawula ezahlukahlukene, ezingahlangabezana nezidingo zokuxhumana kwedatha okusheshayo phakathi kwamadivayisi angaphakathi eseva.
- QSFP 40G SFF-8436 Ukuphela:
- I-QSFP (i-Quad Small Form-factor Pluggable) iyindinganiso yenethiwekhi yesivinini esikhulu, kanti i-SFF-8436 iyincazelo yayo ehambisanayo. I-QSFP interface isekela ukudluliswa kwedatha yesivinini esikhulu sama-40Gbps futhi ivame ukusetshenziswa ezikhungweni zedatha, kumakhompyutha asebenza kahle kakhulu, kumaswishi enethiwekhi nakwamanye amadivayisi, okuvumela ukuxhumana kwenethiwekhi yesivinini esikhulu phakathi kwamadivayisi.
- Lesi sixhumi sinezici ezincane, ezingakwazi ukuxhunywa, kanye nokusekelwa kokushintshana okushisa, okwenza kube lula ukufakwa, ukugcinwa, kanye nokuthuthukiswa kwemishini.
Isici somkhiqizo:
- Umklamo Omuhle Wokuvikela: Ikhebula livame ukuba nesakhiwo esihle sokuvikela, njengesendlalelo sokuvikela sensimbi, njll., esinganciphisa ngempumelelo ithonya lokuphazamiseka kwe-electromagnetic yangaphandle esignalini. Ngesikhathi esifanayo, lingavimbela futhi isignali yangaphakathi ukuthi ingaphazamisi ingaphandle, okuqinisekisa ubumsulwa nobuqotho besignali.

Yiziphi izici zezintambo ze-SAS kanye nezintambo ze-SAS
Ikhebula le-SAS liyinkambu yokugcina yemidiya yediski iyidivayisi ebaluleke kakhulu, yonke idatha nolwazi kufanele lugcinwe kumidiya yediski. Isivinini sokufunda idatha sinqunywa yi-interface yokuxhuma yemidiya yediski. Esikhathini esidlule, besilokhu sigcina idatha yethu ngokusebenzisa izixhumi ze-SCSI noma ze-SATA kanye nama-hard drive. Kungenxa yentuthuko esheshayo yobuchwepheshe be-SATA kanye nezinzuzo ezahlukahlukene ukuthi abantu abaningi bazocabanga ukuthi ikhona yini indlela yokuhlanganisa i-SATA ne-SCSI, ukuze izinzuzo zazo zombili zidlalwe ngesikhathi esisodwa. Kulesi simo, kuvele i-SAS. Amadivayisi okugcina axhunyiwe angahlukaniswa cishe ngezigaba ezintathu ezinkulu, okungukuthi, i-middle-end ephezulu kanye ne-near-end (Near-Line). Amadivayisi okugcina aphezulu ikakhulukazi ayi-Fibre channel. Ngenxa yesivinini sokudlulisa esisheshayo se-Fibre channel, amadivayisi amaningi okugcina i-optical fiber asetshenziswa ekugcinweni kwedatha yokhiye wezinga lomsebenzi omkhulu. Idivayisi yokugcina ephakathi nendawo ikakhulukazi amadivayisi e-SCSI, futhi inomlando omude, isetshenziswa ekugcinweni kwedatha ebalulekile yezinga lokuhweba. Ifushaniswe ngokuthi (SATA), isetshenziswa ekugcinweni okukhulu kwedatha engabalulekile futhi ihloselwe ukufaka esikhundleni sekhophi yokusekelayo yedatha yangaphambilini kusetshenziswa itheyiphu. Inzuzo engcono kakhulu yamadivayisi okugcina i-Fibre Channel ukudluliswa okusheshayo, kodwa inentengo ephezulu futhi kunzima ukuyinakekela; Amadivayisi e-SCSI anokufinyelela okusheshayo kanye nentengo ephakathi, kodwa anwetshiwe kancane, ikhadi ngalinye lesikhombimsebenzisi se-SCSI lixhuma amadivayisi afinyelela ku-15 (isiteshi esisodwa) noma angu-30 (amashaneli amabili). I-SATA ubuchwepheshe obuthuthuka ngokushesha eminyakeni yamuva. Inzuzo yayo enkulu ukuthi ishibhile, futhi ijubane alinciphi kakhulu kunesikhombimsebenzisi se-SCSI. Ngokuthuthuka kobuchwepheshe, isivinini sokufunda idatha se-SATA siyasondela futhi sidlula isikhombimsebenzisi se-SCSI. Ngaphezu kwalokho, njengoba i-hard disk ye-SATA ishibhile futhi ibiza kakhulu, ingasetshenziswa kancane kancane ekulondolozeni idatha. Ngakho-ke isitoreji sebhizinisi sendabuko ngoba uma sicabangela ukusebenza nokuzinza, nge-SCSI hard disk kanye ne-fiber optic channel njengesikhulumi esiyinhloko sokugcina, i-SATA isetshenziswa kakhulu kwidatha engabalulekile noma kwikhompyutha yomuntu siqu yedeskithophu, kodwa ngokukhula kobuchwepheshe be-SATA kanye nemishini ye-SATA evuthiwe, le modi iyashintshwa, abantu abaningi baqala ukunaka i-SATA ngale ndlela yokuxhumeka kwedatha yochungechunge.
