Zosokoneza pa SAS HD SFF-8643 mpaka 4x SATA yotembenuzidwa kapena yowongoka komanso yodutsa

M'munda wa kufala kwakukulu kwa data ndi kusungirako, pogwiritsa ntchitoMini SAS HD Int SFF8643 mpaka 4 SATA chingwendizofunikira pakulumikizana kopanda msoko.Komabe, chisokonezo nthawi zambiri chimabwera pomvetsetsa mitundu yosiyanasiyana ya zingwe zomwe zimafunikira kulumikiza kwa SAS kupita ku SATA.Skyward Telecom (BDC Cable Limited) ndiwotsogola wotsogola wotumiza ndi kusungirako deta, akupereka zinthu zosiyanasiyana zomwe zimagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana monga Ethernet, malo opangira data, cloud computing, magulu apakompyuta apamwamba komanso nyumba zanzeru.

Kuti muchepetse kumvetsetsa kwa zingwezi, ndikofunikira kuzindikira kuti ngati mbali yowongoleredwa ndi cholumikizira cha SAS (SFF-8470) ndipo mbali yomwe mukufuna ndi SATA drive, chingwe cha SAS kupita ku SATA chotsogola chimafunika.Mosiyana ndi izi, ngati mbali ya boardboard / host controller ndi cholumikizira cha SATA ndipo ndege yakumbuyo ndi cholumikizira cha SAS, chingwe cholumikizira cha SAS kupita ku SATA chimafunika.Pamalumikizidwe a SATA kupita ku SATA, gwiritsani ntchito zingwe za "SATA".

Skyward Telecom (BDC Cable Limited) yakhala patsogolo popereka njira zothetsera kusamutsa ndi kusunga deta yayikulu.Zogulitsa zawo, kuphatikiza zingwe za Mini SAS HD Int SFF8643 mpaka 4 SATA, zidapangidwa kuti zikwaniritse zosowa zamakampani.Poyang'ana pa Ethernet, malo opangira data, cloud computing, magulu apamwamba a makompyuta, ndi nyumba zanzeru, kampaniyo yadzipanga yokha ngati wothandizira wodalirika wogwirizanitsa solut.

Zingwe ziwiri zophulika, kutsogolo ndi kumbuyo, sizili zofanana ngakhale kuti zimayang'ana kunja kuti zikhale zofanana, osayang'ana kuti zina mwa zingwezi zimakhala ndi gawo la SATA la zingwe pamtunda wokhazikika ndipo zina zimakhala nazo kutalika kwake.

Chifukwa chiyani pali mitundu iwiri yamitundu yosiyanasiyana yolumikizira SAS kupita ku SATA?Cholinga cha dongosolo la SATA chinali chakuti zingwe za SATA zikhale ndi zolumikizira zofanana kumapeto kulikonse, komanso kuti zida za SATA zikhale ndi zolumikizira zofanana posatengera kuti ndi ma drive a disk kapena owongolera disk.Izi zimathandiza kuti ma interconections asakhale opanda nzeru komanso amachepetsa mtengo wa zingwe.

Mukayang'ana chingwe cha SATA kupita ku SATA ndizofanana komanso zolumikizidwa ngati chingwe cha 1: 1.Mu 1: 1 chingwe pini 1 ya mapeto-A amapita ku pini 1 ya mapeto-B, pini 2 ku pini 2, pini 3 ku pini 3, ndi zina zotero. bolodi la mavabodi ndi cholumikizira cha SATA pa disk drive amawoneka ofanana, ndipo ali ofanana, koma ali ndi mawaya mosiyana.

Cholumikizira cha SATA chili ndi mapini 7.Awiri mwa mapini amapanga awiri olandila ndipo awiri a mapini amapanga awiriwo.Zikhomo zina zitatu zonse zimagwiritsidwa ntchito popanga ma sign apansi.Ngati 1: 1 ("mowongoka-kupyolera") chingwe cha SATA kupita ku SATA chikugwira ntchito, ndiye kuti zolandirira sizingakhale zikhomo zomwezo pazitsulo ziwirizi (Host vs disk)!Ngati anali mapini omwewo ndiye kuti tikadafunikira chingwe chomwe chimatchedwa "wowoloka"."Lamulo Lokwanira" ndiloti zikhomo zotumizira mbali imodzi ziyenera kugwirizanitsa ndi zikhomo zolandirira mbali inayo ndi mosemphanitsa.Izi ndi zoona kwa PC-PC RS232 malumikizidwe, Efaneti Connections, SATA malumikizidwe, ndipo pafupifupi mitundu yonse ya serial malumikizidwe amene ali duplex, mwachitsanzo osiyana kulandira ndi kufalitsa zingwe.

Zolumikizira zonse za SAS zili ndi mapini awo opangidwa mwanjira yomweyo ngakhale zili pamakhadi owongolera, kapena ndege yakumbuyo ya SAS.Popeza pa doko lililonse la zinayi zomwe zimapanga cholumikizira cha SFF-8470 zolumikizira ndi zikhomo zolandirira zili pamalo omwewo, ndipo tiyenera kulumikiza SAS kutumiza ku SATA kulandira ndi SAS kulandira kutumiza kwa SATA (pa doko lililonse);zingwe ziyenera kukhala zosiyana kutengera ngati cholumikizira cha SATA chili pa disk drive kapena Motherboard/Host-Controller.

Chifukwa chake, chingwe cha SAS kupita ku SAS chiyenera kukhala chingwe "chowoloka" cholumikizira ma doko kupita ku madoko omwe amalandila mbali inayo.
