Ukuhlaziywa Okuphelele Kwezintambo ze-SAS: Ukuxhumeka Kwesitoreji Okusebenzayo Okungu-8654, 8087 kanye Nokusebenza Okuphezulu
Esimweni samanje sokubala esidinga idatha eningi, ukusebenza kanye nokuthembeka kwezinhlelo zokugcina kuncike ngqo ezingxenyeni ezixhumanisayo. Ubuchwepheshe be-SAS (Serial Attached SCSI), njengesixhumi esiyinhloko sesitoreji sezinga lebhizinisi, bubone izixazululo zalo zokuxhumeka ngokomzimba zithuthuka ngezizukulwane eziningi, okuholela ezindinganisweni ezahlukene zekhebula. Lesi sihloko sizogxila ekuhlaziyweni kwezingxenye ezintathu ezibalulekile:Ikhebula le-SAS 8654 4i, Ikhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087, futhiIkhebula le-SFF 8087, behlola izindima zabo kanye nezinhlelo zokusebenza ekwakhiweni kwesitoreji okusebenzayo kakhulu.
Ukuhlaziywa Okujwayelekile Okuyinhloko: Kusukela Efomini Lokuxhumana Kuya Kokungafani Kokusebenza
Okokuqala, ake sicacise amazinga obuchwepheshe ahilelekile kulezi zintambo.Ikhebula le-SFF 8087kwakuyidizayini yakudala eyayisetshenziswa kakhulu enkathini ye-SAS 2.0.I-Mini SASI-interface ye-HD inikeza ukuxhumana kweziteshi ezine, isiteshi ngasinye sinomkhawulokudonsa we-6Gb/s.Ikhebula le-SFF 8087, ngezici zayo zikagesi ezizinzile, yayiyinsika eyinhloko yokuxhumanisa ama-array esitoreji kanye nama-backplane eseva ezinsukwini zokuqala futhi isasebenza ezikhungweni eziningi zedatha zendabuko.
Ngokwethulwa kwendinganiso ye-SAS 3.0,Ikhebula le-SAS 8654 4ikwavela. Le ntambo, equketheI-SFF-8654isikhombimsebenzisi, sifinyelela izinga lokudlulisa elingu-12Gb/s elinechweba elilodwa, okuphindwe kabili i-bandwidth yesandulelayo. Okuphawulekayo ukuthi, i-Ikhebula le-SAS 8654 4iigcina ukusebenza okuphezulu ngenkathi ithuthukisa ukusetshenziswa kwesikhala. Idizayini yayo encane ifaneleka kakhulu ezindaweni zokugcina ezinabantu abaningi. Ama-array amaningi esimanje asebenzisa i-all-flash athembele kulokhuIkhebula le-SAS 8654 4iukufeza ukuxhumana okusheshayo phakathi kwabalawuli namakhabhinethi okukhulisa amadiski aqinile.
Izixazululo Zokuxhumana Ezihlanganisiwe: Ibhuloho Phakathi Kwezindinganiso Ezindala Nezintsha
Ezimweni zokuthuthukiswa kwesitoreji sangempela kanye nokwandiswa, kuvamile ukuhlangana nokusetshenziswa okuxubile kwemishini emisha neyakudala. Ezimweni ezinjalo, i-Ikhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087idlala indima ebalulekile yokuhlanganisa. Le ntambo yokuguqula inezimbiliI-SFF-8654izixhumi (ezihlanganisa iziteshi ezingu-8) kolunye uhlangothi, ezisesimweni se-Ikhebula le-SAS 8654 4is, kanye nambiliIkhebula le-SFF 8087okujwayelekileI-Mini SASama-interface ngakolunye uhlangothi.
Umklamo weIkhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087icabangela ukuhambisana kanye nebhalansi yokusebenza. Lapho amabhizinisi exhumanisa abalawuli be-SAS 3.0 besizukulwane esisha namakhabhinethi okukhulisa i-hard disk e-SAS 2.0 asasetshenziswa, lokhuIkhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087iqinisekisa ukuthi uhlelo lusebenza ngokujwayelekile ngenkathi kukhulisa inani lemishini ekhona. Ekusetshenzisweni kwangempela, ukukhethwa kobude kanye nobuqotho besiginali seIkhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087yiba yizinto ezibalulekile okufanele uzicabangele.
Izimo zohlelo lokusebenza kanye nokucatshangelwa kokusetshenziswa
Kwingqalasizinda ehlanganisiwe kakhulu,Ikhebula le-SAS 8654 4iivame ukusetshenziselwa ukuxhumana kwenethiwekhi yokugcina ama-node ngenxa yezici zayo eziphezulu ze-bandwidth. Ngokuphambene nalokho, i-Ikhebula le-SFF 8087kuvame ukutholakala ekuxhumaneni phakathi kwama-backplane e-hard disk kanye nabalawuli be-RAID.Ikhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087isetshenziswa kakhulu ngesikhathi sokuguquka kwezakhiwo ezihlanganisiwe. Lapho amabhizinisi ethatha indawo kancane kancaneIkhebula le-SFF 8087s kanye nentshaIzintambo ze-SAS 8654 4i, le ntambo yokuguqula iqinisekisa inqubo yokuthuthukisa ebushelelezi.
Uma ukhetha lezi zintambo, kubalulekile ukuqaphela ukuthiIkhebula le-SAS 8654 4iiza ngezinguqulo zangaphakathi nezangaphandle;Ikhebula le-SFF 8087kudinga ukuhlukaniswa phakathi kokucushwa okuqondile kanye nokucushwa kwegatsha; kanyeI-SLIM SAS 8654 8I to Ikhebula le-MINI SAS 8087kumele isekele ukuhambisana kwesilinganiso sokudlulisa esidingekayo. Ikhwalithi yekhebula ithinta ngqo izinga lamaphutha e-bit kanye nokuqina kwesistimu, ngakho-ke kunconywa ukukhetha imikhiqizo eqinisekiswe yizinga le-SFF.
Ukuthuthuka kobuchwepheshe kanye nombono wesikhathi esizayo
Ngokuthuthuka kwe-SAS 4.0 standard, ama-interface angu-24Gb/s angena kancane kancane emakethe, kodwaIkhebula le-SAS 8654 4ikanye nemikhiqizo ehlobene nayo izohlala ibalulekile iminyaka eminingana. Kwamabhizinisi amaningi, ukusebenzisa ngokugcwele okukhonaIkhebula le-SFF 8087ingqalasizinda kanye nokufeza ukuthuthukiswa okuqhubekayo ngezixazululo zokuguquka ezifanaIkhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087kuyisinqumo esingabizi kakhulu nesisebenziseka kalula.
Kungakhathaliseki ukuthi kuyinto yakudalaIkhebula le-SFF 8087, okuyinhlokoIkhebula le-SAS 8654 4inomaIkhebula le-SLIM SAS 8654 8I kuya ku-MINI SAS 8087njengesixazululo sesikhashana, ndawonye zakha isisekelo esiqinile sokuxhumeka kwesitoreji sebhizinisi. Ukuqonda izici kanye nezimo zokusetshenziswa kwalezi zintambo kuzosiza abakhi be-IT ukuthi benze izinqumo ezinhle kakhulu maqondana nokusebenza, izindleko, kanye nokuhambisana, futhi bakhe izakhiwo zokugcina idatha ezisebenza kahle futhi ezinokwethenjelwa.
