M.2 (M-Key NVMe 2260) kupita ku SAS SFF-8087 Seva Yolumikizira ndi Kusewera Yokhala ndi Ngodya Yakumanzere Chingwe Chothamanga Kwambiri

Kodi mawaya a SAS ndi mawaya a SAS ndi otani?

Chingwe cha SAS ndi malo osungira zinthu pa disk media ndi chipangizo chofunikira kwambiri, deta yonse ndi chidziwitso ziyenera kusungidwa pa disk media. Kuthamanga kwa deta kumatsimikiziridwa ndi kulumikizana kwa disk media. Kale, nthawi zonse takhala tikusunga deta yathu kudzera mu SCSI kapena SATA interfaces ndi hard drives. Chifukwa cha kupita patsogolo mwachangu kwa ukadaulo wa SATA ndi maubwino osiyanasiyana, anthu ambiri adzaganizira ngati pali njira yophatikizira SATA ndi SCSI, kuti maubwino onse awiri athe kuseweredwa nthawi imodzi. Pankhaniyi, SAS yatulukira. Zipangizo zosungiramo zinthu zolumikizidwa zitha kugawidwa m'magulu atatu akuluakulu, omwe ndi, pakati-mapeto apamwamba komanso pafupi-mapeto (Near-Line). Zipangizo zosungiramo zinthu zapamwamba makamaka ndi Fibre channel. Chifukwa cha liwiro lofulumira la Fibre channel, zida zambiri zosungiramo zinthu zapamwamba zimagwiritsidwa ntchito posungira deta yachinsinsi ya ntchito nthawi yeniyeni. Chipangizo chosungiramo zinthu chapakati makamaka ndi zida za SCSI, ndipo chili ndi mbiri yakale, chikugwiritsidwa ntchito posungira deta yofunika kwambiri yamalonda. Mwachidule, imagwiritsidwa ntchito posungira deta yosafunikira ndipo cholinga chake ndikusintha zosunga deta zakale pogwiritsa ntchito tepi. Ubwino wabwino kwambiri wa zida zosungiramo za Fibre Channel ndi kutumiza mwachangu, koma uli ndi mtengo wokwera ndipo ndi wovuta kusamalira; Zipangizo za SCSI zili ndi mwayi wofikira mwachangu komanso mtengo wapakati, koma ndizochepa pang'ono, khadi lililonse la SCSI limalumikiza zida 15 (single channel) kapena 30 (dual-channel). SATA ndi ukadaulo womwe ukukula mwachangu m'zaka zaposachedwa. Ubwino wake waukulu ndikuti ndi wotsika mtengo, ndipo liwiro lake silichedwa kwambiri kuposa mawonekedwe a SCSI. Ndi chitukuko cha ukadaulo, liwiro la kuwerenga deta la SATA likuyandikira ndipo likupitirira mawonekedwe a SCSI. Kuphatikiza apo, pamene hard disk ya SATA ikutsika mtengo komanso yokwera mtengo, ingagwiritsidwe ntchito pang'onopang'ono posungira deta. Chifukwa chake kusungirako kwachikhalidwe kwa bizinesi chifukwa poganizira magwiridwe antchito ndi kukhazikika, ndi SCSI hard disk ndi fiber optic channel ngati nsanja yayikulu yosungiramo, SATA imagwiritsidwa ntchito kwambiri pa data yosafunikira kapena kompyuta yapakompyuta, koma chifukwa cha kukwera kwa ukadaulo wa SATA ndi zida za SATA, mawonekedwe awa akusinthidwa, anthu ambiri adayamba kulabadira njira iyi yolumikizirana yosungira deta.
