Ukuphonononga i-Mini SAS, i-SAS, kunye ne-HD IiNdidi zePort SAS ezincinci kuQhagamshelwano lweDatha

Kwimeko ehlala iguquguquka yokugcina idatha kunye nokudluliselwa, ukubaluleka koqhagamshelwano olusebenzayo noluthembekileyo alukwazi ukugqithiswa.Phakathi kwamawaka eeqhagamshela kunye namachweba akhoyo, i-Mini SAS (i-Serial Attached SCSI), i-SAS (i-Serial Attached SCSI), kunye ne-HD Mini ye-SAS ivelele njengamacandelo abalulekileyo kwiindawo ezisebenza kakhulu zedatha.Kweli nqaku, siza kuphonononga kwiimpawu, izicelo, kunye nezibonelelo zezi ntlobo zezibuko.

1. UkuqondaSAS(Isiriyali iqhotyoshelwe kwi-SCSI)

I-SAS, okanye i-Serial Attached SCSI, yiprotocol yokudlulisa idatha yesantya esiphezulu esetyenziselwa ikakhulu ukudibanisa izixhobo zokugcina ezifana ne-hard drives, i-slid-state drives, kunye ne-tape drives kwiiseva kunye neendawo zokusebenza.Idibanisa izibonelelo ze-SCSI (I-Interface yeNkqubo yeKhompyutha encinci) kunye nojongano lwe-serial, enikezela ukwanda kwe-scalability, ukuthembeka, kunye nokusebenza.

Iimpawu eziphambili ze-SAS:

• Isantya: I-SAS ixhasa amazinga okudluliselwa kwedatha ukuya kwi-12 Gb / s (SAS 3.0), kunye nokuphindaphinda kamva njenge-SAS 4.0 ethembisa isantya esiphezulu.
• Ukuhambelana: I-SAS iyahambelana ngasemva, ivumela abasebenzisi ukuba badibanise izixhobo ezindala ze-SAS kunye nabalawuli abatsha be-SAS.
• I-Point-to-Point Architecture: Uxhulumaniso ngalunye lwe-SAS lubandakanya ikhonkco phakathi komqalisi (umkhosi) kunye nethagethi (isixhobo sokugcina), ukuqinisekisa i-bandwidth ezinikeleyo.

2. Intshayelelo kuI-SAS encinci

I-Mini SAS, edla ngokubizwa ngokuba yi-SFF-8087 okanye i-SFF-8088, luhlobo oludityanisiweyo lwesidibanisi se-SAS esenzelwe indawo ezixineneyo.Ngaphandle kobukhulu bayo buncinci, i-Mini SAS igcina amandla esantya esiphezulu se-SAS, iyenza ibe lolona khetho lufanelekileyo kwizicelo apho indawo iyiprimiyamu.

Iindidi zeziNxibelelwano ze-SAS ezincinci:

• I-SFF-8087: Ngokuqhelekileyo isetyenziswe ngaphakathi, esi siqhagamshelo sine-36-pin configuration, inikezela ngeendlela ezine zedatha.
• I-SFF-8088: Isetyenziselwa uxhulumaniso lwangaphandle, i-SFF-8088 ibonisa ukucwangciswa kwe-26-pin kwaye ihlala iqeshwe kwizisombululo zokugcina ezifuna uxhulumaniso lwangaphandle.

3. HD Mini SAS– Ukutyhala iMida

I-HD Mini SAS, eyaziwa ngokuba yi-SFF-8644 okanye i-SFF-8643, imele ukuqhubela phambili kwamva nje kuqhagamshelwano lwe-SAS.Yakha phezu kwesiseko esibekwe yi-Mini SAS, izisa ifom yefom encinci kunye nokuphucula amandla okusebenza.

Iimpawu eziphawulekayo ze-HD Mini SAS:

• Uyilo lweCompact: Ngonyawo oluncinci kune-Mini SAS, i-HD Mini SAS ifaneleke kakuhle usetyenziso apho ukulungelelaniswa kwendawo kubalulekile.
• Ukunyuka kweNkcukacha yeDatha: I-HD Mini SAS isekela amazinga aphezulu okudlulisa idatha, ukufikelela kwi-24 Gb / s (SAS 3.2), okwenza kube yinto efanelekileyo kwimisebenzi ye-bandwidth-intensive.
• Ukuguquguquka okuphuculweyo: Uyilo lokudibanisa luvumela ukhetho oluninzi oluguquguqukayo lwe-cabling, igalelo ekuphuculeni ulawulo lwekhebula.

4. Izicelo kunye neeNgqwalasela

• Ukugcinwa koShishino: Izixhumi ze-SAS zifumana ukusetyenziswa ngokubanzi kwizisombululo zokugcina ishishini, ukubonelela ngoqhagamshelwano oluthembekileyo noluphezulu phakathi kweeseva kunye nezixhobo zokugcina.
• AmaZiko eeNkcukacha: I-Mini SAS kunye ne-HD Mini SAS zisetyenziswa rhoqo kwiindawo zamaziko edatha apho i-cabling esebenzayo kunye nokudluliselwa kwedatha ngesantya esiphezulu kubaluleke kakhulu.
• Ii-Arrays zokugcinwa kwangaphandle: I-SFF-8088 kunye ne-HD Mini ye-SAS izixhumi zisetyenziswa ngokuqhelekileyo ukudibanisa ii-arrays zokugcina zangaphandle, ukuququzelela utshintshiselwano lwedatha olukhawulezayo noluthembekileyo.

5. Isiphelo

Kwihlabathi elikhawulezayo lolawulo lwedatha, ukhetho lweziqhagamshelo ludlala indima ebalulekileyo ekunqumeni ukusebenza kakuhle kunye nokuthembeka kwenkqubo yonke.I-SAS, i-Mini ye-SAS, kunye ne-HD Mini ye-SAS imele imida ekuphuhlisweni koqhagamshelwano lwedatha, inika uluhlu lweendlela zokukhetha ukuhlangabezana neemfuno ezahlukeneyo zeemeko zekhompyutha zanamhlanje.Njengoko itekhnoloji iqhubela phambili, ezi ziqhagamshelo ziya kudlala indima ebaluleke ngakumbi ekubumbeni ikamva lokugcina idatha kunye nokudluliselwa.
