Esimeni esiguqukayo njalo sokugcinwa nokudluliswa kwedatha, ukubaluleka kokuxhumana okuphumelelayo nokuthembekile ngeke kuqiniswe.Phakathi kwezinkulungwane zezixhumi namachweba atholakalayo, iMini SAS (i-Serial Attached SCSI), i-SAS (Serial Attached SCSI), kanye ne-HD Mini SAS zigqama njengezingxenye ezibalulekile ezindaweni zedatha esebenza kahle kakhulu.Kulesi sihloko, sizocubungula izici, izinhlelo zokusebenza, kanye nezinzuzo zalezi zinhlobo zamachweba.
1. UkuqondaSAS(Serial Anamathiselwe SCSI)
I-SAS, noma i-Serial Attached SCSI, iyiphrothokholi yokudluliswa kwedatha enesivinini esikhulu esetshenziswa ngokuyinhloko ukuxhuma izinto zokugcina ezifana nama-hard drive, amadrayivu e-solid-state, namadrayivu etheyiphu kumaseva naseziteshini zokusebenza.Ihlanganisa izinzuzo ze-SCSI (I-Small Computer System Interface) nesixhumi esibonakalayo se-serial, enikeza ukukala okukhuphukile, ukwethembeka, kanye nokusebenza.
Izici ezibalulekile ze-SAS:
- Isivinini: I-SAS isekela izilinganiso zokudluliswa kwedatha ezifika ku-12 Gb/s (SAS 3.0), ngokuphindaphinda kamuva okufana ne-SAS 4.0 ethembisa isivinini esikhulu nakakhulu.
- Ukuhambisana: I-SAS ihambisana nemuva, ivumela abasebenzisi ukuthi baxhume amadivayisi amadala e-SAS nezilawuli ezintsha ze-SAS.
- I-Point-to-Point Architecture: Uxhumo ngalunye lwe-SAS ngokuvamile luhilela isixhumanisi sokukhomba-kuya-iphuzu phakathi komqalisi (umsingathi) kanye nethagethi (idivayisi yesitoreji), okuqinisekisa umkhawulokudonsa ozinikele.
2. Isingeniso kuI-Mini SAS
I-Mini SAS, evame ukubizwa ngokuthi i-SFF-8087 noma i-SFF-8088, iwuhlobo oluhlangene lwesixhumi sakwa-SAS esiklanyelwe izindawo ezinomkhawulo wesikhala.Naphezu kobukhulu bayo obuncane, i-Mini SAS igcina amandla esivinini esikhulu se-SAS, okuyenza ibe ukukhetha okuhle kwezinhlelo zokusebenza lapho isikhala siyiprimiyamu.
Izinhlobo zezixhumi ze-Mini SAS:
- I-SFF-8087: Ngokuvamile isetshenziswa ngaphakathi, lesi sixhumi sinokucushwa kwamaphini angu-36, sinikeza imizila emine yedatha.
- I-SFF-8088: Isetshenziselwa ukuxhumeka kwangaphandle, i-SFF-8088 ihlanganisa ukucushwa kwe-26-pin futhi ivame ukuqashwa ezixazululweni zesitoreji ezidinga uxhumano lwangaphandle.
3. I-HD Mini SAS– Ukusunduza Imikhawulo
I-HD Mini SAS, eyaziwa nangokuthi i-SFF-8644 noma i-SFF-8643, imele intuthuko yakamuva ekuxhumekeni kwe-SAS.Yakha phezu kwesisekelo esakhiwe yi-Mini SAS, yethula isici sefomu encane kanye namakhono okusebenza athuthukisiwe.
Izici eziphawulekayo ze-HD Mini SAS:
- Idizayini Ehlangene: Ngonyawo oluncane kune-Mini SAS, i-HD Mini SAS ifaneleka kahle izinhlelo zokusebenza lapho ukulungiselelwa kwendawo kubaluleke kakhulu.
- Ukudluliswa Kwedatha Enyusiwe: I-HD Mini SAS isekela amazinga aphezulu okudluliswa kwedatha, afinyelela ku-24 Gb/s (SAS 3.2), okwenza ilungele imisebenzi edinga umkhawulokudonsa.
- Ukuvumelana nezimo Okuthuthukisiwe: Idizayini yesixhumi ivumela izinketho eziningi zekhebula eziguquguqukayo, okunikela ekuphathweni okuthuthukisiwe kwekhebula.
4. Izicelo Nokucatshangelwa
- Isitoreji Sebhizinisi: Izixhumi ze-SAS zithola ukusetshenziswa okubanzi kuzixazululo zesitoreji sebhizinisi, zinikeza ukuxhumana okuthembekile nokusebenzayo okuphezulu phakathi kwamaseva namadivayisi okugcina.
- Izikhungo Zedatha: I-Mini SAS ne-HD Mini SAS zivame ukusetshenziswa ezindaweni zesikhungo sedatha lapho ukubamba ikhebula okuphumelelayo nokudluliswa kwedatha ngesivinini esikhulu kubaluleke kakhulu.
- I-External Storage Arrays: Izixhumi ze-SFF-8088 kanye ne-HD Mini SAS zivame ukusetshenziselwa ukuxhuma izinhlelo zesitoreji sangaphandle, kube lula ukushintshaniswa kwedatha okusheshayo nokuthembekile.
5. Isiphetho
Ezweni elisheshayo lokuphathwa kwedatha, ukukhetha kwezixhumi kudlala indima ebalulekile ekunqumeni ukusebenza kahle nokuthembeka kwalo lonke uhlelo.I-SAS, i-Mini SAS, kanye ne-HD Mini SAS imele ingqopha-mlando ekuthuthukisweni kokuxhumana kwedatha, enikeza izinhlobonhlobo zezinketho ukuze kuhlangatshezwane nezidingo ezihlukahlukene zendawo yesimanje yamakhompyutha.Njengoba ubuchwepheshe buqhubeka buthuthuka, lezi zixhumi cishe zizodlala indima ebaluleke nakakhulu ekulolongeni ikusasa lokugcinwa nokudluliswa kwedatha.
