SAS-mawilo: lakuti, ofotokoza, makhalidwe luso chipangizo

Kugula mizere kapena Seva kuti mudziwe sitolo, tileke kutsogolo kwa kusankha: wotani chosungira anaika. Wotchuka kwambiri ndi mitundu zotsatirazi abulusa molimbika: SAS, SATA ndi NL-SAS. mitundu awa atatu a yachangu TV yosungirako, iwo anali ambiri deta mu dziko. Nkhani athu anagona pa mtundu woyamba. Ife timayang'ana pa zomwe ali SAS-abulusa, komanso magawo awo, ndipo kodi pali kusiyana pakati pa mitundu zofunika zipangizozi.

makhalidwe luso

SAS-mawilo m'malo SCSI-mtundu. Achita muyezo latsopano zambiri yosungirako ogwira kalasi. Za mitundu itatu SAS-abulusa amaonedwa odalirika kwambiri, iwo akukhalabe ntchito mu zinthu zovuta opaleshoni. abulusa SAS kuchita mtundu bwino NL abulusa kapena SATA. Chizindikiro waima kudalirika chizindikiro monga mlingo pang'ono kulakwitsa. Izo zimatengera momwe ayenera pang'ono zolakwa umodzi kumachitika mu deta TV. Mlingo mphulupulu mtundu SAS HDD ndi amangoona gulu la 10 ¹⁶ Tinthu. Ndiko kuti, zikutanthauza kuti Mwina kulakwa kumachitika munthu mmodzi mwa anthu khumi quadrillion Akamva. Mwachitsanzo, tingathe kuyerekezera mlingo ndi kufunika zolakwa mu SATA mtundu molimba litayamba, kumene kuli mmodzi wa 10 ¹⁵ (kapena wina quadrillion). Monga Tingaone chitetezo SATA-HDD ndi ndithu mkulu Komabe, pali funso za chitetezo deta kusungidwa, kusiyana kwa dongosolo ndi wofunika kwambiri.

SAS-mawilo opangidwa mwa kutsatira mfundo okhwima kuposa mu chitukuko cha zina abulusa. Choncho njira imeneyi amakhala ndi nthawi zikutanthauza pakati pa zolephera, maola 1.6 miliyoni ndipo SATA-Technology - 1.2 miliyoni. Kuwonjezera magawo awa, opha ndi abulusa wa mtundu uwu ndi malamulo ambiri amene anafuna matenda. zizindikiro zimenezi kupanga njira imeneyi imayenera kuposa SATA. Izi zimaonekera makamaka milandu mphamvu majeure.

NL-abulusa

Njira imeneyi ndi "latsopano player" pa msika. NL-mawilo ndi hybrid: SATA-HDD ndi SAS mtundu cholumikizira. Ndiko kuti, liwiro ndi kudzazidwa mutu anatengedwa kuchokera SATA-luso, mawonekedwe ndi kwathunthu yogwirizana ndi SAS. NL-luso ankaona mbale otsika mu ntchito (chifukwa rotational liwiro wotsika). Komabe, kwathunthu mogwirizana ndi iwo mu dongosolo la magulu a anthu, komanso Mipikisano kusonkhana ndi thandizo makamu angapo.

Tagirovannaya kuti kutumiza malamulo Mipikisano kusonkhana

Munthawi yomweyo ntchito akanema angapo yosungirako chikalata, ndi kusunga Mtsogoleri analamula zambiri imafalikira efficiently kwambiri. SAS-luso amapereka njira zingapo zonse duplex wa deta yomwe imapatsa mwamsanga mudziwe kusungidwa. Mmodzi chosungira SAS-mtundu akhoza lizilamuliridwa ku ma PC angapo popanda masiwichi.

Pomaliza

Ndipotu, SAS ndi SATA umisiri tinapangidwa zolinga zosiyana; koyamba chifukwa cha kulolerana vuto ndi ntchito, ndipo chachiwiri - kuonetsetsa muli ndi. Choncho iwo alibe kupikisana wina ndi mzake.
