Iterambere ry'ikoranabuhanga rya SAS Connector: Impinduramatwara yo kubika ibintu kuva kuri Parallel kugeza kuri High-Speed ​​Serial

Sisitemu zo kubika amakuru muri iki gihe ntizikura gusa ku rwego rwa terabit, zifite igipimo cyo kohereza amakuru kiri hejuru, ahubwo zinakoresha ingufu nke kandi zigafata umwanya muto. Izi sisitemu nazo zisaba guhuza neza kugira ngo zitange uburyo bworoshye bwo koroshya. Abashushanya bakeneye uburyo buke bwo guhuza amakuru kugira ngo batange igipimo cyo kohereza amakuru gikenewe ubu cyangwa mu gihe kizaza. Kandi bifata igihe kirenze umunsi umwe kugira ngo ikintu runaka kibeho, gitere imbere kandi gitere buhoro buhoro. Cyane cyane mu nganda z'ikoranabuhanga, ikoranabuhanga iryo ari ryo ryose rihora ritera imbere kandi ritera imbere, kandi SAS (Serial Attached SCSI, Serial SCSI) specification ntabwo ari uko bimeze. Nk'umusimbura wa SCSI isanzwe, SAS specification imaze igihe kinini mu bantu.

Mu myaka myinshi SAS imaze ikora, imiterere yayo yakomeje kunozwa. Nubwo protocole y’ibanze itahindutse cyane, imiterere y’ibihuza by’inyuma byagiye bihinduka kenshi. Iri ni ihinduka ryakozwe na SAS kugira ngo rihuze n’imiterere y’isoko. Urugero, iterambere ry’ibiranga connector nka MINI SAS 8087, SFF-8643, na SFF-8654 ryahinduye cyane uburyo bwo guhuza imiyoboro y’amashanyarazi kuko SAS yahindukaga kuva ku ikoranabuhanga rijyanye n’ikoranabuhanga rijyanye n’ikoranabuhanga. Mbere, SCSI ijyanye n’imiyoboro y’amashanyarazi yashoboraga gukora kugeza kuri 320 Mb/s ku mirongo 16 mu buryo bumwe cyangwa butandukanye. Kuri ubu, ihuriro rya SAS 3.0, rigikoreshwa cyane mu kubika amakuru mu bigo, ritanga bandwidth yihuta inshuro ebyiri kurusha SAS 3 idafite ikoranabuhanga rigezweho, igera kuri 24 Gbps, bingana na 75% by’umurongo w’amashanyarazi wa PCIe 3.0 x4 solid-state drive isanzwe. Umuhuza uheruka wa MiniSAS HD uvugwa muri specification ya SAS-4 ni muto kandi ushobora kugera ku bucucike bwinshi. Ingano y'umuhuza wa Mini-SAS HD uheruka ni kimwe cya kabiri cy'umuhuza wa SCSI wa mbere na 70% by'umuhuza wa SAS. Bitandukanye n'umuhuza wa SCSI wa mbere, SAS na Mini-SAS HD byombi bifite imiyoboro ine. Ariko, hamwe n'umuvuduko mwinshi, ubucucike bwinshi, no koroha cyane, hariho no kwiyongera k'ubugoranye. Kubera ko umuhuza ari muto, abakora insinga, abateranya insinga, n'abashushanya sisitemu bagomba kwitondera cyane ibipimo by'ubuziranenge bw'ibimenyetso by'umuhuza wose w'insinga.

Ubwoko bwose bw'insinga za SAS n'ibihuza, biroroshye cyane kuzishyira zigaragara neza cyane… Ni zingahe wabonye? Zikoreshwa mu nganda, n'izikoreshwa mu bicuruzwa bicuruzwa? Urugero, insinga ya MINI SAS 8087 kugeza kuri 4X SATA 7P Male, insinga ya SFF-8643 kugeza kuri SFF-8482, SlimSAS SFF-8654 8i, n'ibindi.

Ubugari (ibumoso, hagati) bw'insinga ya Mini-SAS HD ni 70% by'insinga ya SAS (iburyo).

Si abakora insinga bose bashobora gutanga ibimenyetso byihuse cyane kugira ngo bahuze n'ibisabwa ku buryo bw'ubuziranenge bw'ibimenyetso by'uburyo bwo kubika. Abakora insinga bagomba gutanga ibisubizo byiza kandi bihendutse kuri sisitemu zigezweho zo kubika. Urugero, insinga ya SFF-8087 kuri SFF-8088 cyangwa insinga ya MCIO 8i kuri 2 OCuLink 4i. Kugira ngo hakorwe ibice by'insinga bihamye kandi biramba, hari ibintu byinshi bigomba kwitabwaho. Uretse kubungabunga ubuziranenge bw'uburyo bwo gutunganya no gutunganya, abashushanya bagomba kandi kwita cyane ku bipimo by'ubuziranenge bw'ibimenyetso, ari na byo bituma insinga zo kubika ibikoresho byihuse cyane muri iki gihe zishoboka.
