Isishwankathelo seCable ye-SAS Ukusuka kwi-Internal Interconnection 8087 ukuya kwi-External High-Speed 8654
Xa sisakha okanye siphucula iinkqubo zokugcina izinto ezikumgangatho ophezulu, iindawo zokusebenza ezisebenza kakuhle, okanye izixhobo ezithile ze-NAS, sihlala sidibana neentambo ezahlukeneyo ezibonakala zifana. Phakathi kwazo, iintambo ezinxulumene ne-"MINI SAS" zibalulekile kodwa zinokudida. Namhlanje, siza kujonga "Intambo ye-MINI SAS 8087 ukuya kwi-8654 4i"kwaye"Intambo ye-MINI SAS 8087"ukukunceda uqonde ngokucacileyo iindlela ezisetyenziswa ngazo kunye nomahluko azo."
I. Ukuqonda okusisiseko: Yintoni i-MINI SAS?
Okokuqala, i-SAS (Serial Attached SCSI) yiprotocol esetyenziselwa ukuqhagamshela nokulawula izixhobo zangaphandle zekhompyutha, ingakumbi ii-hard disk drives. Ithathe indawo yetekhnoloji ye-SCSI ehambelanayo endala. I-MINI SAS luhlobo olubonakalayo lwe-SAS interface, oluncinci kune-SAS interfaces zangaphambili kwaye lunokubonelela ngoqhagamshelo lwe-bandwidth ephezulu kwiindawo ezilinganiselweyo.
Ngexesha lokuvela kwe-MINI SAS, kuye kwavela iimodeli ezahlukeneyo zojongano, phakathi kwazo i-SFF-8087 kunye ne-SFF-8654 ngabameli ababini ababalulekileyo.
I-MINI SAS 8087 (SFF-8087): Le yimodeli yakudala yesixhumi sangaphakathi se-MINI SAS. Yi-interface enamaphini angama-36, edla ngokusetyenziselwa ukuqhagamshela i-motherboard (ikhadi le-HBA) kwi-backplane okanye ngokuthe ngqo kwii-hard drive ezininzi. I-interface enye ye-SFF-8087 idibanisa iziteshi ezine ze-SAS, nganye ine-bandwidth yethiyori ye-6Gbps (kuxhomekeke kwinguqulelo ye-SAS, inokuba yi-3Gbps okanye i-12Gbps), ngoko ke i-bandwidth iyonke inokufikelela kwi-24Gbps.
I-MINI SAS 8654 (SFF-8654): Lo ngumgangatho omtsha wesixhumi sangaphandle, odla ngokubizwa ngokuba yiMini SAS HD. Ukwanazo neephini ezingama-36 kodwa uncinci ngokwasemzimbeni kwaye uncinci ngakumbi kuyilo. Usetyenziswa kakhulu ukuqhagamshela iiports zangaphandle zezixhobo, ezifana ne-server host ukuya kwikhabhinethi yediski yangaphandle. I-interface enye ye-SFF-8654 ikwaxhasa iitshaneli ezine ze-SAS kwaye iyahambelana ne-SAS 3.0 (12Gbps) kunye neenguqulelo eziphezulu.
II. Uhlalutyo oluPhambili: Intambo ye-MINI SAS 8087 ukuya kwi-8654 4i
Ngoku, makhe sigxile kwigama elingundoqo lokuqala:Intambo ye-MINI SAS 8087 ukuya kwi-8654 4i.
Ukusuka kwigama, sinokutolika ngokuthe ngqo:
Isiphelo esinye yi-SFF-8087 interface (interface yangaphakathi)
Esinye isiphelo yi-SFF-8654 interface (i-interface yangaphandle)
I-"4i" idla ngokumela "iitshaneli ezi-4 ngaphakathi", apha inokuqondwa njengoko le ntambo inonxibelelwano olupheleleyo lwe-4-channel SAS.
Yintoni umsebenzi oyintloko wale ntambo? - "Yibhulorho" edibanisa indawo yokugcina ulwandiso lwangaphakathi nolwangaphandle lweseva.
Iimeko eziqhelekileyo zesicelo:
Khawuthelekelele ukuba une-tower server okanye i-workstation enekhadi le-HBA kwi-motherboard ene-interface ye-SFF-8087. Ngoku, kufuneka uqhagamshele ikhabhinethi ye-SAS disk array yangaphandle, kwaye i-interface yangaphandle yale khabhinethi ye-disk array yi-SFF-8654 ngqo.
Ngeli xesha,Intambo ye-MINI SAS 8087 ukuya kwi-8654 4iiyasebenza. Ufaka isiphelo se-SFF-8087 kwikhadi le-HBA langaphakathi leseva, kwaye uqhagamshele isiphelo se-SFF-8654 kwizibuko lekhabhinethi yediski yangaphandle. Ngale ndlela, iseva inokuqaphela kwaye ilawule zonke ii-hard drives kwikhabhinethi yediski.
Ngamazwi alula, lo ngumgca woqhagamshelo "ovela ngaphakathi ukuya ngaphandle", ofezekisa ukudluliselwa kwedatha okungenamthungo nokukhawulezayo ukusuka kumlawuli we-SAS ngaphakathi kwiseva ukuya kwisixhobo sokugcina sangaphandle.
III. Ukuqonda okuthelekisayo:Intambo ye-MINI SAS 8087
Igama lesibini elingundoqo elithi "MINI SAS 8087 Cable" lithetha ingcinga ebanzi, ebhekisa kwintambo enesiphelo esinye okanye zombini ezizi-interfaces ze-SFF-8087. Idla ngokusetyenziselwa uqhagamshelo lwangaphakathi lwezixhobo.
Iindidi eziqhelekileyo zeMini SAS 8087 Cable ziquka:
Uhlobo loqhagamshelo ngqo (SFF-8087 ukuya kwi-SFF-8087): Uhlobo oluqhelekileyo, olusetyenziselwa uqhagamshelo ngqo phakathi kwekhadi le-HBA kunye ne-backplane yeseva.
Uhlobo lwesebe (i-SFF-8087 ukuya kwi-4x SATA/SAS): Isiphelo esinye yi-SFF-8087, kwaye esinye isiphelo siphuma siye kwii-4 ezizimeleyo ze-SATA okanye ze-SAS data interfaces. Le ntambo idla ngokusetyenziselwa ukuqhagamshela ikhadi le-HBA ngqo kwii-4 ezizimeleyo ze-SATA okanye ze-SAS hard drives ngaphandle kokudlula kwi-backplane.
Uhlobo lwesebe elibuyela umva (SFF-8087 ukuya kwi-SFF-8643): Isetyenziselwa ukuqhagamshela amakhadi amadala e-HBA asemgangathweni anee-interfaces ezihlaziyiweyo (ezifana ne-SFF-8643) kwi-backplane okanye kwi-hard drives.
Umahluko ophambili ukusuka kwintambo ye-8087 ukuya kwi-8654:
Indawo yesicelo: Intambo ye-MINI SAS 8087 isetyenziswa kakhulu kwi-chassis yeseva; ngelixa intambo ye-8087 ukuya kwi-8654 isetyenziswa ngokukodwa ukuqhagamshela izixhobo zangaphakathi nezangaphandle.
Indawo yokusebenza: Eyokuqala yintambo "yokunxibelelana kwangaphakathi", ngelixa eyesibini yintambo "yebhuloho langaphakathi-ngaphandle".
