I-Evolution ye-SAS Connector Technology: I-Storage Revolution ukusuka kwi-Parallel ukuya kwi-Speed-Speed Series

Iinkqubo zokugcina zanamhlanje azikhuli kuphela kwinqanaba le-terabit, zinezinga eliphezulu lokudlulisa idatha, kodwa zisebenzisa amandla amancinci kwaye zithatha indawo encinci. Ezi nkqubo zikwafuna uqhagamshelo olungcono ukubonelela ngokuguquguquka ngakumbi. Abaqulunqi badinga unxibelelwano oluncinci ukubonelela ngamazinga akhoyo okanye kwixesha elizayo elifunekayo lokudluliselwa kwedatha. Kwaye kuthatha ngaphezulu kosuku ukuba ingcaciso izalwe, ikhule kwaye ivuthwe ngokuthe ngcembe. Ngokukodwa kwishishini le-IT, nayiphi na iteknoloji ihlala iphucula kwaye iguquka, kwaye i-SAS (i-Serial Attached SCSI, i-Serial SCSI) inkcazo ayikho. Njengomlandeli we-SCSI ehambelanayo, iinkcukacha ze-SAS bezikwimbono yabantu kangangexesha elithile.

Kule minyaka i-SAS ikhona, iinkcukacha zayo bezisoloko ziphuculwa. Nangona i-protocol esisiseko ihleli ingatshintshi kakhulu, ukucaciswa kwezixhumi ze-interface zangaphandle ziye zatshintsha ezininzi. Olu luhlenga-hlengiso olwenziwe yi-SAS ukuziqhelanisa nokusingqongileyo kwemarike. Umzekelo, ukuvela kwezinto ezidityanisiweyo ezinje nge-MINI SAS 8087, SFF-8643, kunye ne-SFF-8654 zitshintshe kakhulu izisombululo zecabling njengoko i-SAS itshintshela kwi-parallel ukuya kwi-serial technology. Ngaphambili, i-SCSI enxuseneyo yayinokusebenza ukuya kuthi ga kwi-320 Mb/s phezu kwamajelo ali-16 ngendlela enesiphelo esinye okanye esahlukileyo. Okwangoku, i-interface ye-SAS 3.0, esasetyenziswa ngokubanzi kwisitoreji seshishini, inika i-bandwidth ephindwe kabini ngokukhawuleza njenge-SAS 3 yexesha elide elingaphuculwanga, ifikelela kwi-24 Gbps, malunga ne-75% ye-bandwidth ye-PCIe eqhelekileyo 3.0 x4 i-solid-state drive. Isidibanisi se-MiniSAS HD samva nje esichazwe kwinkcazo ye-SAS-4 sincinci ngobukhulu kwaye sinokufikelela ekuxineni okuphezulu. Ubungakanani bomdibaniso we-Mini-SAS HD wamva nje sisiqingatha seso siqhagamshelo sokuqala se-SCSI kunye ne-70% yekhonkco le-SAS. Ngokungafaniyo nentambo yokuqala ye-SCSI ehambelanayo, zombini i-SAS kunye ne-Mini-SAS HD zineziteshi ezine. Nangona kunjalo, kunye nesantya esiphezulu, ukuxinana okuphezulu, kunye nokuguquguquka okukhulu, kukwakho ukwanda kobunzima. Ngenxa yokuba isinxibelelanisi sincinci, abavelisi bekhebula, abahlanganisi bekhebula, kunye nabaqulunqi benkqubo kufuneka banikele ingqwalasela enkulu kwiiparamitha zengqibelelo yomqondiso wendibano yonke yentambo.

Zonke iintlobo zeentambo ze-SAS neziqhagamshelo, kulula ngenene ukuzenza zibukeke zikhazimla… Zingaphi ozibonileyo? Ezo zisetyenziswa kwishishini, kunye nezo zemveliso yabathengi? Umzekelo, i-MINI SAS 8087 ukuya kwi-4X SATA 7P Ikhebula le-Male, i-SFF-8643 ukuya kwi-SFF-8482 cable, i-SlimSAS SFF-8654 8i, njl.

Ububanzi (ekhohlo, phakathi) bentambo ye-Mini-SAS HD yi-70% yaleyo yentambo ye-SAS (ekunene).

Akunabo bonke abavelisi beentambo abanokubonelela ngeempawu eziphezulu zesantya esiphezulu ukuhlangabezana neemfuno zesignali yemfezeko yeenkqubo zokugcina. Abavelisi beekhebula kufuneka banike izisombululo ezikumgangatho ophezulu kunye neendleko ezifanelekileyo kwiinkqubo zokugcina zamva nje. Ngokomzekelo, i-SFF-8087 ukuya kwi-SFF-8088 cable okanye i-MCIO 8i ukuya kwi-2 OCuLink 4i intambo. Ukuvelisa amacandelo ekhebula espeed-speed ezinzile kwaye ehlala ixesha elide, izinto ezininzi kufuneka ziqwalaselwe. Ukongeza kokugcina umgangatho wokucubungula kunye nenkqubo yokucubungula, abaqulunqi nabo kufuneka bahlawule ingqwalasela enkulu kwiiparamitha zengqibelelo yomqondiso, eyona nto ibangela ukuba iintambo zesixhobo sokugcina isantya esiphezulu senzeke.
