Kwihlabathi lanamhlanje ledijithali, apho ukufikelela kwedatha kunye nezantya zokudlulisa kubaluleke kakhulu, ukuqonda iintlobo zezixhumanisi ezisetyenziswa kwiinkqubo zokugcina kubalulekile. Olunye ujongano olunjalo olwafumana ukutsaleka ekuqaleni kweminyaka yoo-2000 yi isidibanisi se-eSATA, mfutshane ye Uthotho lwangaphandle Advanced Technology Attachment. Yaphuhliswa ukwandisa i IIYURE ujongano ngaphaya kwe-chassis yangaphakathi, ivumela uxhulumaniso lwesantya esiphezulu kwiihard drives zangaphandle kunye ne-SSD.
Ngokungafaniyo nemveli i-USB okanye FireWire imidibaniso, iziqhagamshelo ze-eSATA umnikelo ukufikelela ngqo kwinkqubo yebhasi, eyenza ugqithiso lwedatha olukhawulezayo nolusebenzayo. Oku kubenza balungele abahleli bevidiyo, Iingcali ze-IT, kunye nabani na ofuna ukugcinwa kwangaphandle okuphezulu.
Eli nqaku lichaza yonke into ofuna ukuyazi ngayo amazibuko eSATA, kuquka nezabo uyilo lobugcisa, iingenelo, imida, kunye nendlela ezithelekisa ngayo I-USB 3.0, Indudumo, kunye nemigangatho emitsha. Nokuba wakha inkqubo, uphucula indawo yokugcina, okanye ulawula izixhobo zelifa, uyayiqonda indlela i-eSATA interface umsebenzi unokukunceda wenze izigqibo zehardware ezikrelekrele.
Ekupheleni, uya kuba nomfanekiso ocacileyo wokuba uqhagamshelwano lwe-eSATA isabalulekile kwikhompuyutha yale mihla—okanye ukuba lixesha lokudlulela kunxibelelwano olutsha, oluguquguqukayo.
II. I-Evolution kunye neMbali yezihlanganisi ze-eSATA
Ibali le iziqhagamshelo ze-eSATA iqala ngendaleko ye SATA (Isiriyali ATA) ujongano. Yaziswa ekuqaleni kweminyaka yoo-2000, IIYURE ibuyiselwe ngokukhawuleza KUVALIWE ngenxa yamaxabiso edatha akhawulezayo kunye neentambo ezibhityileyo. Nangona kunjalo, njengoko izixhobo zokugcina zangaphandle ziye zaxhaphaka, abasebenzisi bafuna isisombululo esihambelanayo izantya zeSATA zangaphakathi—oku kukhokelele kuphuhliso lwe eSATA kwi 2004, yenziwe ngokusesikweni yi SATA-IO (Serial ATA International Organisation).
eSATA (SATA yangaphandle) yenzelwe ukubonelela a uqhagamshelo oluzinikeleyo, olukwisantya esiphezulu kwiidrive zangaphandle ngaphandle kokuncama ukusebenza. Ngokungafaniyo I-USB 2.0, efikelele kwi-480 Mbps, I-eSATA inikezela ukuya kuthi ga kwi-3 Gbps (SATA II) kwaye kamva I-6 Gbps (SATA III)-ilungele imisebenzi efana nokuhlelwa kwevidiyo kunye nokugcinwa kwexesha lokwenyani.
Ixesha elidlulele, eSATAP (eSATA) yaziswa, kudityaniswa i-USB kwaye eSATA kwizibuko elinye, ngokongezwa ukuhanjiswa kwamandla. Oku kujolise ekoyiseni eyona miqobo inkulu ye-eSATA: ukunqongophala kobonelelo lwamandla emveli.
Ngaphandle kweenzuzo zayo zokusebenza, Ukuthandwa kwe-eSATA kwehlile njengoko I-USB 3.0 kwaye Indudumo yavela, inikezela ngezantya ezikhawulezayo, iplagi kunye nokudlala lula, kunye nokuhambelana kwendawo yonke. Sekunjalo, I-eSATA ihlala ifanelekile ngokuqinisekileyo ishishini kwaye ikhompuyutha yelifa iindawo apho isantya kunye nokuzinza zibekwe phambili kunoncedo.
III. Isebenza njani i-eSATA?
eSATA (Uthotho lwangaphandle ATA) imisebenzi usebenzisa i iprotocol efanayo kwaye umqondiso wedatha njengangaphakathi Uqhagamshelwano lweSATA, kodwa ngeeyantlukwano ezibalulekileyo zomzimba kunye nombane ezilungiselelwe ukusetyenziswa kwangaphandle. Olu yilo luvumela i-eSATA ukuba inikezele ukudluliselwa kwedatha ngesantya esiphezulu-ixhomekeke ku I-6 Gbps kunye ne-SATA III-ngokuthe ngqo phakathi kwesixhobo sokugcina sangaphandle kunye nenkqubo yokusingatha, kugqitha isilawuli se-USB ngaphezulu.
Ngokungafaniyo USB okanye FireWire, eguqula idatha ngeebhulorho zeprotocol, I-eSATA ibonelela ngoqhagamshelwano lwendalo kwenkqubo Umlawuli we-SATA, ukunciphisa i-latency kunye nokwandisa ukugqithisa. Olu fikelelo oluthe ngqo luguqulela kwi ukusebenza okuhambelanayo, ngakumbi xa usebenza ngeefayile ezinkulu okanye ukusasaza idatha ngexesha langempela.
Iimpawu eziphambili zendlela esebenza ngayo i-eSATA ibandakanya:
-
Indawo yolwakhiwo lwendawo — uqhagamshelwano oluthe ngqo phakathi komncedisi kunye nesixhobo
-
Iintambo ezikhuselekileyo - Nciphisa ukuphazamiseka kwe-electromagnetic (EMI)
-
Ubude bentambo ende - ixhasa ukuya kuthi ga 2 yeemitha, ngokungafaniyo nomda wangaphakathi weSATA wemitha eyi-1
-
Inkxaso eshushu-swappable — ifumaneka kuphela xa inkqubo isetyenziswa Imowudi ye-AHCI
I uyilo lwesihlanganisi ngokwayo yahlukile-iziqhagamshelo ze-eSATA zomelele ngakumbi, azinasitshixo “emilise ngo-L” se-SATA yangaphakathi, kwaye zibuyiselwe umva ukunqanda ukuqhawuka ngempazamo.
Kwimeko, I-eSATA ivala ukusebenza kweSATA yangaphakathi kunye nokuguquguquka kokufikelela kwangaphandle, okwenza kube lukhetho oluqinileyo kwiingcali ezidingayo ethembekileyo, ukugcinwa kwangaphandle kwesantya esiphezulu.
IV. Intambo ye-eSATA kunye neempawu zeSiqhagamshelo
Ngokungafaniyo nemveli i-USB okanye FireWire iintambo, iintambo ze-eSATA kunye nezihlanganisi zenzelwe ngokukodwa ugqithiso lwedatha yangaphandle enesantya esiphezulu ngelixa ugcina uphawu lwemfezeko. Ezi ntambo zi ikhuselwe Ukunqanda uphazamiseko lwe-electromagnetic (EMI) kwaye zakhelwe ukugcina i amandla ombane aphezulu efunekayo kunxibelelwano lwangaphandle.
Iimpawu eziphambili zeentambo ze-eSATA zibandakanya:
-
Ubuninzi bentambo yobude ye 2 yeemitha, xa kuthelekiswa nomda we-SATA wemitha eyi-1
-
Ulwakhiwo olukhuselekileyo ukukhusela kwilahleko yedatha kunye nokuphazamiseka
-
Ukuqina okuphezulu, ilinganiswe malunga 5,000 imijikelo yokufaka/yokususa
-
Akukho qhosha elimilise ngo L, ngokungafaniyo nezixhumi ze-SATA zangaphakathi, ukukhusela ukudideka komsebenzisi
-
Abafowunelwa abaphindiweyo kusetyenziso lwangaphandle olukhuselekileyo kunye nokunciphisa umonakalo womzimba
I isidibanisi se-eSATA ikwayilwe nge iindawo zoqhagamshelwano ezilayishwe entwasahlobo kwaye iimpawu zokugcina eziqinileyo, ukuqinisekisa uxhulumaniso olukhuselekileyo noluthembekileyo lwee-hard drives zangaphandle kunye nee-SSD.
Ngelixa ezi ziqhagamshelo zinganikezeli amandla (ngokungafaniyo USB okanye eSATAp), bayagqwesa isantya esiphezulu, ukudluliselwa kwedatha okuzinzileyo-esona sizathu siphambili sokuba iingcali zithembele kubo iinkqubo zeRAID zangaphandle, ugcino lwemidiya, kwaye ugcino oluncamathele ngqo (DAS).
Xa umgangatho kunye nokusebenza kubaluleke ngaphezu kokulula, Uyilo olukhethekileyo lwe-eSATA iqinisekisa ukusebenza okuthembekileyo kuzo zombini iiseti zabathengi nakwimizi-mveliso.
