Emkhakheni wokudluliswa kwedatha enkulu nokugcinwa, usebenzisaIkhebula elincane le-SAS HD Int SFF8643 ukuya ku-4 SATAibalulekile ekuxhumekeni okungenamthungo.Nokho, ukudideka kuvame ukuvela uma kuziwa ekuqondeni izinhlobo ezahlukene zezintambo ezidingekayo ekuxhumekeni kwe-SAS kuya ku-SATA.I-Skyward Telecom (BDC Cable Limited) ingumhlinzeki omkhulu wokudluliswa kwedatha nokugcinwa kwedatha, ehlinzeka ngezinhlobonhlobo zemikhiqizo esetshenziswa kabanzi emikhakheni ehlukahlukene efana ne-Ethernet, izikhungo zedatha, i-cloud computing, amaqoqo amakhompyutha anedatha ephezulu kanye namakhaya ahlakaniphile.
Ukwenza lula ukuqonda kwalawa makhebuli, kubalulekile ukuqaphela ukuthi uma uhlangothi lwesilawuli sosokhaya luyisixhumi se-SAS (SFF-8470) futhi uhlangothi oluqondiwe luyidrayivu ye-SATA, ikhebula le-SAS ukuya ku-SATA eliya phambili liyadingeka.Ngokuphambene, uma uhlangothi lwesilawuli sebhodi lomama/umsingathi luyisixhumi se-SATA futhi ibhanoyi elingemuva liyisixhumi se-SAS, intambo yokuhlehla ye-SAS kuya ku-SATA iyadingeka.Ukuze uthole uxhumano lwe-SATA kuya ku-SATA, sebenzisa izintambo ezijwayelekile ze-“SATA”.
I-Skyward Telecom (BDC Cable Limited) ibihamba phambili ekuhlinzekeni ngezixazululo zokudluliswa nokugcinwa kwedatha enkulu.Imikhiqizo yabo, okuhlanganisa iMini SAS HD Int SFF8643 kuya kuzintambo ezi-4 SATA, zenzelwe ukuhlangabezana nezidingo eziguqukayo zemboni.Ngokugxila ku-Ethernet, izikhungo zedatha, i-cloud computing, amaqoqo amakhompiyutha edatha ephezulu, kanye namakhaya ahlakaniphile, inkampani izenzele njengomhlinzeki onokwethenjelwa we-solut yokuxhuma.
Izintambo ezimbili ezinqamukayo, eziya phambili nangemuva, azifani nakuba zibukeka ngaphandle ziyafana, zingamelani neqiniso lokuthi amanye alawa makhebuli anengxenye ye-SATA yezintambo ngobude obunyakazayo kanti ezinye zinabo ngobude obunqunyiwe.
Kungani kunezinhlobo ezimbili zamakhebula ezihlukene zokuxhuma i-SAS kuya ku-SATA?Inhloso yomklamo wesistimu ye-SATA bekungukuthi izintambo ze-SATA zizoba nezixhumi ezifanayo ekugcineni ngakunye, nokuthi amadivayisi we-SATA abe nezixhumi ezifanayo ngaphandle kokuthi zingamadrayivu ediski noma izilawuli zediski.Lokhu kusiza ekwenzeni ama-interconections angasebenzi futhi kunciphisa izindleko zezintambo.
Uma kwenzeka ubheka intambo ye-SATA kuye kwe-SATA ziyefana futhi zinezintambo njengekhebula elingu-1:1.Kuphinikhodi yekhebula engu-1:1 1 we-end-A iya kuphini elingu-1 lokuphela-B, phina u-2 ukuze uphine 2, phina u-3 ukuze uphine u-3, njll. Uma ubungabheka isixhumi se-SATA kusilawuli sokusingatha noma ibhodi lomama nesixhumi se-SATA ku-disk drive zibukeka zifana, futhi ziyafana ngokomzimba, kodwa ngayinye inezintambo ezihlukile.
Isixhumi se-SATA sinamaphinikhodi angu-7.Izikhonkwane ezimbili zakha ipheya eyamukelayo kanti izikhonkwane ezimbili zakha ipheya yokudlulisa.Ezinye izikhonkwane ezintathu zonke zisetshenziselwa amasignali aphansi.Uma ikhebula engu-1:1 (“idlule iqonde”) ye-SATA iye ku-SATA izosebenza, lapho-ke ipheya eyamukelwe ngeke ibe amaphinifa afanayo kusixhumi ngasinye kwezimbili zedivayisi (I-Host vs disk)!Ukube bekuyizikhonkwane ezifanayo besizodinga lokho ngokuvamile okubizwa ngokuthi ikhebula “le-cross-over”."Umthetho Ophelele" wukuthi izikhonkwane zokudlulisa ohlangothini olulodwa kufanele zixhumeke kumaphini okwamukela ngakolunye uhlangothi futhi ngokuphambene nalokho.Lokhu kuyiqiniso ngoxhumo lwe-PC-PC RS232, i-Ethernet Connections, uxhumano lwe-SATA, futhi cishe nazo zonke izinhlobo zokuxhunywa kwe-serial okuyi-duplex, okungukuthi izintambo ezihlukene zokwamukela nokudlulisa.
Zonke izixhumi ze-SAS zinezikhonkwane zazo ezihlelwe ngendlela efanayo kungakhathaliseki ukuthi zikukhadi lesilawuli somsingathi, noma indiza engemuva ye-SAS.Njengoba kuchweba ngalinye kwezine ezakha isixhumi se-SFF-8470 amaphinikhodi okudlulisela namaphinikhodi atholayo asendaweni efanayo ngokomzimba, futhi kufanele sixhume ukuthunyelwa kwe-SAS kokuthola kwe-SATA futhi i-SAS yamukele ekudluliseni kwe-SATA (kumbobo ngayinye);izintambo kufanele zehluke kuye ngokuthi isixhumi se-SATA sikudiski drive noma i-Motherboard/Host-Controller.
Ngakho-ke ikhebula ye-SAS eya kwa-SAS kufanele kube ikhebula “ewela ngaphesheya” ukuze ixhume amapheya echweba kumapheya amukelayo embobo ehambisanayo ngakolunye uhlangothi.
