MINI SAS HD 8643 Dual-Port kupita ku HD SFF-8643 Dual-Port Yolumikizidwa Seva Yapamwamba-Liwiro Lolumikizira Chingwe

Kodi zingwe za SAS ndi zingwe za SAS ndi ziti

Chingwe cha SAS ndiye malo osungiramo ma disk media ndi chida chofunikira kwambiri, zidziwitso zonse ndi zidziwitso ziyenera kusungidwa pa media media. Kuthamanga kowerengera kwa data kumatsimikiziridwa ndi mawonekedwe olumikizira a disk media. M'mbuyomu, takhala tikusunga deta yathu kudzera pa SCSI kapena SATA interfaces ndi hard drive. Ndi chifukwa cha chitukuko chofulumira cha teknoloji ya SATA ndi ubwino wosiyanasiyana womwe anthu ambiri angaganizire ngati pali njira yophatikizira SATA ndi SCSI, kotero kuti ubwino wa zonsezi ukhoza kuseweredwa nthawi imodzi. Pankhaniyi, SAS yatulukira. Zipangizo zosungiramo maukonde zitha kugawidwa m'magulu atatu akuluakulu, omwe ndi apamwamba kwambiri apakati komanso pafupi-kumapeto (Near-Line). Zida zosungirako zotsika kwambiri zimakhala makamaka Fiber channel. Chifukwa cha kuthamanga kwachangu kwa Fiber channel, zipangizo zambiri zosungirako zosungirako zosungirako zosungirako zimagwiritsidwa ntchito kusungirako zenizeni zenizeni zenizeni za deta yofunikira. Chipangizo chosungirako chapakati makamaka ndi zipangizo za SCSI, komanso zimakhala ndi mbiri yakale, zomwe zimagwiritsidwa ntchito posungirako misala ya deta yovuta kwambiri yamalonda. Chidule cha (SATA), chimagwiritsidwa ntchito posungirako zinthu zambiri zosafunikira ndipo cholinga chake ndikusintha zosunga zobwezeretsera zam'mbuyomu pogwiritsa ntchito tepi. Ubwino wabwino wa zida zosungirako za Fiber Channel ndikutumiza mwachangu, koma uli ndi mtengo wapamwamba ndipo ndizovuta kuzisamalira; Zipangizo za SCSI zili ndi mwayi wofikira mwachangu komanso zamtengo wapakatikati, koma ndizotalikirako pang'ono, khadi lililonse la SCSI limalumikizana ndi zida 15 (njira imodzi) kapena 30 (njira ziwiri). SATA ndiukadaulo womwe ukukula mwachangu m'zaka zaposachedwa. Ubwino wake waukulu ndikuti ndi wotchipa, ndipo liwiro silochedwa kwambiri kuposa mawonekedwe a SCSI. Ndi chitukuko chaukadaulo, liwiro la kuwerenga kwa data la SATA likuyandikira ndikupitilira mawonekedwe a SCSI. Kuphatikiza apo, popeza hard disk ya SATA ikutsika mtengo komanso yokwera mtengo, imatha kugwiritsidwa ntchito pang'onopang'ono posunga zosunga zobwezeretsera. Chifukwa chake kusungirako kwamabizinesi achikhalidwe chifukwa poganizira momwe magwiridwe antchito amagwirira ntchito komanso kukhazikika, ndi SCSI hard disk ndi fiber optic njira ngati nsanja yayikulu yosungira, SATA imagwiritsidwa ntchito kwambiri pazinthu zosafunikira kapena makompyuta apakompyuta, koma ndi kukwera kwaukadaulo wa SATA ndi zida za SATA. okhwima, mode izi zikusinthidwa, anthu ambiri anayamba kulabadira SATA iyi siriyo deta yosungirako kugwirizana njira.
