Zithini umahluko phakathi kweI-MINI SAS 36Pintambo yeadaptha kunye nentambo ye-8087?
Kwiziko ledatha lanamhlanje, kwiindawo zokusebenzela ezisebenza kakuhle, kunye nezisombululo zokugcina ezikumgangatho weshishini, ukuhanjiswa kwedatha okuzinzileyo nokukhawulezayo yeyona nto iphambili ekusebenzeni kwenkqubo. Ikhonkco eliphambili lokufezekisa le njongo lidla ngokuxhomekeka kwii-interfaces ezikhethekileyo kunye neentambo. Phakathi kwazo,Intambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pkwaye iIntambo ye-MINI SAS 8087zidlala indima ebalulekileyo. Nangona ezi ntambo zimbini zinamagama afanayo, zahlukile kuyilo, usetyenziso, kunye ne-topology, zakha kunye itshaneli yedatha esebenzayo ukusuka kumlawuli ukuya kwisixhobo sokugcina idatha.
Okokuqala, masigxile kwiIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pIgama lale ntambo libonisa ngokucacileyo umsebenzi wayo: elinye icala liyiI-MINI SAS 36P(ekwaziwa ngokuba yi-SFF-8087) isixhumi sesilisa, esisetyenziselwa ukuqhagamshela kwicala le-host (ezifana namakhadi e-HBA okanye abalawuli be-RAID); esinye isiphelo zizixhumi ezininzi ze-SATA 7-pin (ujongano lwedatha oluqhelekileyo lwe-SATA) zesifazane. Olu yilo luvumela isixhumi esinyeIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pukwahlula i-bandwidth ephezulu ye-singleI-MINI SASichwetheza kwiitshaneli ezininzi ze-SATA ezizimeleyo. Ngokwesiqhelo, umgangathoIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pingadibanisa ii-hard drive ezine ze-SATA ngaxeshanye okanye ii-solid-state drives, nto leyo efezekisa ukusetyenziswa kwakhona kwee-port ngokufanelekileyo. Kwiimeko apho izixhobo ezininzi ze-SATA kufuneka ziqhagamshelwe kodwa ujongano lwebhodi yomama lulinganiselwe,Intambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pngokungathandabuzekiyo sisisombululo esingabizi kakhulu nesilula. Xa iinjineli ziceba uqhagamshelo lwe-backplane okanye ii-arrays zokugcina eziqhotyoshelwe ngqo, zihlala zibeka phambili ukuvavanya iinkcukacha kunye nobude beIintambo zabasetyhini ze-MINI SAS 36P ukuya kwi-SATA 7pUkukhetha umgangatho ophezuluIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pkubalulekile ekuqinisekiseni ukuthembeka kwesignali kunye nokuphepha iimpazamo zokudluliselwa kwedatha. Ke ngoko, ukuchaza ngokucacileyoIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pehlangabezana neemfuno zenkqubo kuluhlu lokuthengwa kwempahla yinkqubo eqhelekileyo.
Kwelinye icala,Intambo ye-MINI SAS 8087idla ngokubhekisa kwintambo eneziphelo zombini ezinemigangathoI-MINI SAS 8087(SFF-8087) ujongano. Eli gama livela ngokuthe ngqo kwiinkcukacha ezibonakalayo zojongano olusebenzisayo.Intambo ye-MINI SAS 8087isetyenziswa kakhulu ukuqhagamshela izixhobo zehardware kunyeI-MINI SASii-interfaces, ezinje ngokuqhagamshela ikhadi le-HBA (i-Host Bus Adapter) yeseva kwi-backplane ye-disk array esebenzisa i-I-MINI SASujongano. Ngokungafaniyo neentambo zeadaptha ezifakwe iifolokhwe, umgangathoIntambo ye-MINI SAS 8087ifumana ikhonkco elihlanganisiweyo le-bandwidth ephezulu ukusuka kwindawo ukuya kwindawo.Intambo ye-MINI SAS 8087idibanisa iitshaneli ezine ze-SAS ngaphakathi, inikezela nge-bandwidth epheleleyo emangalisayo. Xa kusakhiwa indawo yokugcina i-SAS efuna umbane ophezulu kakhulu kunye nokuthembeka,Intambo ye-MINI SAS 8087licandelo elisisiseko eliyimfuneko. Abahlanganisi beenkqubo babala ngononophelo indlela yokuhambisa indlela yeIntambo ye-MINI SAS 8087xa ufaka iingcingo ngaphakathi kwikhabhinethi ukuze uphephe ukugoba okugqithisileyo okunokuchaphazela ukusebenza. Nokuba kukwandiswa kwendawo yokugcina izinto yangaphakathi okanye uqhagamshelo lwangaphandle lwe-JBOD, isitaliIntambo ye-MINI SAS 8087ayibalulekanga. Iimpawu ezahlukeneyo zeIintambo ze-MINI SAS 8087zinokwahluka ngokweengqimba zokukhusela kunye nobugcisa bokudibanisa, kodwa imisebenzi yazo ephambili ihlala ifana. Abasebenzi bokulungisa badla ngokufuna ukujonga ukuba ziyahambelana na izinto ezikhoyoIintambo ze-MINI SAS 8087ngeenkcukacha ezintsha zehardware xa kuphuculwa okanye kutshintshwa izixhobo.
Ukudibanisa ezi zimbini,Intambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pkwaye iIntambo ye-MINI SAS 8087xa zidibene zenza "imithambo ephambili" kunye "neendlela zokufikelela" kwinethiwekhi yokugcina izinto. Imeko eqhelekileyo yesicelo yile: iseva iqhagamshela isilawuli se-RAID kwi-backplane ye-chassis ngokusebenzisa i-internalIntambo ye-MINI SAS 8087, kwaye i-backplane emva koko isasaza imiqondiso ye-SAS edityanisiweyo kwi-SATA hard drive nganye ngokusebenzisa ezininziIintambo zabasetyhini ze-MINI SAS 36P ukuya kwi-SATA 7pKolu lwakhiwo lwezakhiwo,Intambo ye-MINI SAS 8087iqinisekisa ukuhamba kwedatha ngesantya esiphezulu ukusuka kumlawuli ukuya kwi-backplane, ngelixaIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pUkuqonda uxanduva lomntu ngamnyeIntambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pkwaye nganyeIntambo ye-MINI SAS 8087sisiseko soyilo olusebenzayo lwenkqubo yokugcina izinto, ukuxilongwa kweempazamo, kunye nokwandiswa komthamo.
Ngamafutshane, kwixesha elilandela isantya sokufikelela kwedatha, iinkcukacha zobugcisa ezibonakala zincinci zeentambo zimisela umgangatho wokusebenza kwenkqubo yonke yokugcina idatha.Intambo yabasetyhini ye-MINI SAS 36P ukuya kwi-SATA 7pifezekisa ukuguqulwa kweprotocol kunye nokwandiswa kwezibuko, ngelixaIntambo ye-MINI SAS 8087iqinisekisa uqhagamshelo olukhawulezayo olungenalahleko kwindawo ecocekileyo ye-SAS.
