Uhlalutyo Olupheleleyo lweeCables ze-SAS: 8654, 8087 kunye noQhagamshelo lweSitoreji esiSebenzayo kakhulu
Kule meko yanamhlanje yokubala eneenkcukacha ezininzi, ukusebenza kunye nokuthembeka kweenkqubo zokugcina kuxhomekeke ngokuthe ngqo kwizinto ezidibanisayo. Itekhnoloji ye-SAS (Serial Attached SCSI), njengesixhobo esiphambili sokugcina izinto kwinqanaba leshishini, ibone izisombululo zayo zonxibelelwano zitshintsha kwizizukulwana ezininzi, nto leyo ekhokelela kwimigangatho eyahlukeneyo yekhebula. Eli nqaku liza kujonga kuhlalutyo lwezinto ezintathu ezibalulekileyo:Intambo ye-SAS 8654 4i, Intambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087kunyeIntambo ye-SFF 8087, behlola iindima zabo kunye nokusetyenziswa kwazo kwizakhiwo zokugcina izinto ezisebenza kakuhle.
Uhlalutyo oluPhambili lweMigangatho: Ukusuka kwiFomu yoNxibelelwano ukuya kuMmahluko woKusebenza
Okokuqala, masicacise imigangatho yobugcisa ebandakanyekayo kwezi ntambo.Intambo ye-SFF 8087yayiyilwelo elidala elalisetyenziswa kakhulu kwixesha le-SAS 2.0.I-Mini SASI-interface ye-HD inika uqhagamshelo lweetshaneli ezi-4, apho itshaneli nganye ine-bandwidth yethiyori ye-6Gb/s.Intambo ye-SFF 8087, ngeempawu zayo zombane ezizinzileyo, yayiyeyona nto iphambili yokudibanisa ii-arrays zokugcina kunye nee-backplanes zeseva kwimihla yokuqala kwaye isasebenza kwiindawo ezininzi zedatha zemveli.
Ngokwaziswa komgangatho we-SAS 3.0,Intambo ye-SAS 8654 4iyavela. Le ntambo, equlatheI-SFF-8654ujongano, lufikelela kwisantya sothumelo lwe-12Gb/s esinezibuko elinye, luphinda kabini i-bandwidth yowangaphambili. Okuphawulekayo kukuba, iIntambo ye-SAS 8654 4iigcina ukusebenza okuphezulu ngelixa iphucula ukusetyenziswa kwendawo. Uyilo lwayo oluncinci lufanelekile ngokukodwa kwiindawo zokugcina ezinoxinano olukhulu. Ii-array ezininzi zanamhlanje ze-all-flash zixhomekeke kokuIntambo ye-SAS 8654 4iukufezekisa unxibelelwano olukhawulezayo phakathi kwabalawuli kunye neekhabhathi zokwandisa iidiski ezinzima.
Izisombululo zoQhagamshelo lweHybrid: Ibhulorho phakathi kweMigangatho emidala nentsha
Kwiimeko zokuphucula indawo yokugcina izinto kunye nokwandisa, kuqhelekile ukudibana nokusetyenziswa okuxutyiweyo kwezixhobo ezintsha nezindala. Kwiimeko ezinjalo, izixhoboIntambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087idlala indima ebalulekileyo yokudibanisa. Le ntambo yokuguqula inezinto ezimbiniI-SFF-8654ii-interfaces (ezizonke zi-8 channels) kwelinye icala, ezikwisimbo seIntambo ye-SAS 8654 4is, kunye nezimbiniIntambo ye-SFF 8087umgangathoI-Mini SASii-interfaces kwelinye icala.
Uyilo lweIntambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087iqwalasela ukuhambelana kunye nokulinganisela ukusebenza. Xa amashishini edibanisa abalawuli be-SAS 3.0 besizukulwana esitsha kunye neekhabhathi zokwandisa iidiski ezinzima ze-SAS 2.0 ezisasetyenziswa, okuIntambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087iqinisekisa ukuba inkqubo isebenza ngokuqhelekileyo ngelixa inyusa ixabiso lezixhobo ezikhoyo. Ekusetyenzisweni kwayo, ukukhethwa kobude kunye nokuthembeka kwesignaliIntambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087zibe zizinto ezibalulekileyo ekufuneka ziqwalaselwe.
Iimeko zesicelo kunye nokuqwalaselwa kokusasazwa
Kwiziseko zophuhliso ezidityaniswe kakhulu,Intambo ye-SAS 8654 4iidla ngokusetyenziselwa ukunxibelelana kwenethiwekhi yokugcina ii-node ngenxa yeempawu zayo eziphezulu ze-bandwidth. Ngokwahlukileyo koko, i-Intambo ye-SFF 8087ifumaneka kakhulu kunxibelelwano phakathi kwee-backplanes zediski enzima kunye nabalawuli be-RAID.Intambo ye-SLIM SAS 8654 8I ukuya kwi-MINI SAS 8087isetyenziswa kakhulu ngexesha lotshintsho lwezakhiwo ezixutyiweyo. Xa amashishini etshintsha kancinci kancinciIntambo ye-SFF 8087kunye nentshaIintambo ze-SAS 8654 4i, le ntambo yokuguqula iqinisekisa inkqubo yokuphucula egudileyo.
Xa ukhetha ezi ntambo, kubalulekile ukuqaphela ukubaIntambo ye-SAS 8654 4iiza kwiinguqulelo zangaphakathi nezangaphandle;Intambo ye-SFF 8087kufuneka kwahlulwe phakathi koqwalaselo oluthe tye nolwamasebe; kwayeI-SLIM SAS 8654 8I to Intambo ye-MINI SAS 8087kufuneka ixhase ukuhambelana okufunekayo kwesantya sokudlulisa.
