Chisinthiko cha SAS Connector Technology: A Storage Revolution kuchokera ku Parallel kupita ku High-Speed seri

Zosungirako zamasiku ano sizimangokulira pamlingo wa terabit, zimakhala ndi maulendo apamwamba otumizira deta, komanso zimawononga mphamvu zochepa komanso zimatenga malo ochepa. Machitidwewa amafunikanso kugwirizanitsa bwino kuti apereke kusinthasintha. Okonza amafunikira kulumikizana kung'ono kuti apereke mitengo yaposachedwa kapena yamtsogolo yomwe ikufunika kusamutsa deta. Ndipo zimatengera kupitilira tsiku limodzi kuti chitsimikiziro chibadwe, kukula ndikukhwima pang'onopang'ono. Makamaka mumakampani a IT, ukadaulo uliwonse ukuyenda bwino komanso kusinthika, ndipo mafotokozedwe a SAS (Serial Attached SCSI, Serial SCSI) nawonso. Monga wolowa m'malo wofanana ndi SCSI, mafotokozedwe a SAS akhala akuwoneka kwa anthu kwakanthawi.

Pazaka zomwe SAS yakhala ikuzungulira, mawonekedwe ake akhala akukonzedwa mosalekeza. Ngakhale kuti ndondomeko yoyambirayo yakhala yosasinthika, zofotokozera za zolumikizira zakunja zasintha kangapo. Uku ndikusintha kopangidwa ndi SAS kuti agwirizane ndi msika. Mwachitsanzo, kusinthika kwa zolumikizira monga MINI SAS 8087, SFF-8643, ndi SFF-8654 zasintha kwambiri mayankho a ma cabling pomwe SAS idasintha kuchoka kuukadaulo kupita kuukadaulo. M'mbuyomu, SCSI yofananira imatha kugwira ntchito mpaka 320 Mb/s pa tchanelo cha 16 munjira imodzi yokha kapena yosiyana. Pakadali pano, mawonekedwe a SAS 3.0, omwe amagwiritsidwabe ntchito kwambiri posungira mabizinesi, amapereka bandwidth yomwe imathamanga kuwirikiza kawiri kuposa SAS 3 yosasinthika, kufika 24 Gbps, yomwe ili pafupifupi 75% ya bandwidth wamba PCIe 3.0 x4 solid-state drive. Chojambulira chaposachedwa cha MiniSAS HD chofotokozedwa m'mafotokozedwe a SAS-4 ndi chocheperako mukukula ndipo chimatha kukwaniritsa kachulukidwe kwambiri. Kukula kwa cholumikizira chaposachedwa cha Mini-SAS HD ndi theka la cholumikizira choyambirira cha SCSI ndi 70% ya cholumikizira cha SAS. Mosiyana ndi chingwe choyambirira cha SCSI chofananira, onse a SAS ndi Mini-SAS HD ali ndi mayendedwe anayi. Komabe, pamodzi ndi liwiro lapamwamba, kachulukidwe kakang'ono, ndi kusinthasintha kwakukulu, palinso kuwonjezeka kwa zovuta. Chifukwa cholumikizira ndi chaching'ono, opanga zingwe, ophatikiza zingwe, ndi opanga makina ayenera kusamala kwambiri ndi magawo a chizindikiro cha gulu lonse la chingwe.

Mitundu yonse ya zingwe za SAS ndi zolumikizira, ndizosavuta kuzipangitsa kuti ziziwoneka bwino kwambiri… Mwaziwona zingati? Zomwe zimagwiritsidwa ntchito m'makampani, ndi zomwe zimagwiritsidwa ntchito ndi ogula? Mwachitsanzo, chingwe cha MINI SAS 8087 mpaka 4X SATA 7P Male, chingwe cha SFF-8643 mpaka SFF-8482, SlimSAS SFF-8654 8i, ndi zina zotero.

M'lifupi (kumanzere, pakati) kwa chingwe cha Mini-SAS HD ndi 70% ya chingwe cha SAS (kumanja).

Sikuti onse opanga zingwe angapereke zizindikiro zothamanga kwambiri kuti akwaniritse zofunikira zachinsinsi za makina osungira. Opanga zingwe amayenera kupereka njira zapamwamba komanso zotsika mtengo zosungirako zatsopano. Mwachitsanzo, chingwe cha SFF-8087 kupita ku SFF-8088 kapena MCIO 8i mpaka chingwe cha 2 OCuLink 4i. Kuti apange zigawo za chingwe chokhazikika komanso chokhazikika, pali zinthu zingapo zomwe ziyenera kuganiziridwa. Kuwonjezera pa kusunga khalidwe la kukonza ndi kukonza, okonza amafunikanso kumvetsera kwambiri zizindikiro za kukhulupirika kwa chizindikiro, zomwe ndizomwe zimapangitsa kuti zingwe zamakono zosungirako zitheke.
