Ubhidekile kwi-SAS HD SFF-8643 ukuya kwi-4x SATA ibuyiselwe umva okanye ithe tye kunye ne-crossover

Kwintsimi yokudluliselwa kwedatha enkulu kunye nokugcinwa, usebenzisaMini SAS HD Int SFF8643 ukuba 4 SATA cableibalulekile kuqhagamshelwano olungenamthungo.Nangona kunjalo, ukudideka kuhlala kuvela xa kufikwa ekuqondeni iintlobo ezahlukeneyo zeentambo ezifunekayo kwi-SAS ukuya kuqhagamshelo lwe-SATA.I-Skyward Telecom (i-BDC Cable Limited) ngumboneleli omkhulu ohamba phambili wokuhanjiswa kwedatha kunye nokugcinwa kwedatha, enikezela uluhlu lweemveliso ezisetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana ne-Ethernet, amaziko edatha, i-computing yefu, iqoqo lekhompyutheni yedatha ephezulu kunye namakhaya ahlakaniphile.

Ukwenza lula ukuqonda kwezi ntambo, kubalulekile ukuba uqaphele ukuba ukuba icala lomlawuli we-host liyi-SAS connector (SFF-8470) kunye necala elijoliswe kuyo yi-SATA drive, i-SAS ukuya kwi-SATA intambo yokuphuma phambili iyafuneka.Ngokwahlukileyo, ukuba i-motherboard / i-host controller icala sisidibaniso se-SATA kwaye i-backplane isiqhagamshelanisi se-SAS, i-SAS ukuya kwi-SATA i-reverse breakout cable iyafuneka.Kuqhagamshelwano lwe-SATA ukuya kwi-SATA, sebenzisa iintambo eziqhelekileyo "zeSATA".

I-Skyward Telecom (i-BDC Cable Limited) ibihamba phambili ekuboneleleni ngezisombululo zokuhanjiswa nokugcinwa kwedatha enkulu.Iimveliso zabo, kubandakanywa i-Mini SAS HD Int SFF8643 kwiintambo ze-SATA ze-4, zenzelwe ukuhlangabezana neemfuno eziguqukayo zeshishini.Ngokugxininisa kwi-Ethernet, amaziko edatha, i-computing yefu, iqoqo leekhompyutheni zedatha ephezulu, kunye namakhaya ahlakaniphile, inkampani izenzele njengomboneleli othembekileyo woqhagamshelwano lwe-solut.

Iintambo ezimbini zokuqhawula, phambili kunye nokubuyisela umva, azifani nangona zijonge ngaphandle zifana, zingamelana nento yokuba ezinye zezi ntambo zineengxenye ze-SATA zeentambo ngobude obunqamlekileyo kwaye ezinye zinexesha elide.

Kutheni kukho iindidi ezimbini ezahlukeneyo zeentambo ze-SAS ukuya kuqhagamshelo lwe-SATA?Injongo yoyilo lwenkqubo ye-SATA yayikukuba iintambo ze-SATA ziya kuba neziqhagamshelo ezifanayo kwisiphelo ngasinye, kwaye izixhobo ze-SATA ziya kuba neziqhagamshelo ezifanayo ezizimeleyo nokuba ziziqhubo zediski okanye abalawuli bedisk.Oku kunceda ukwenza ii-interconections zingasebenzi kwaye kunciphisa ixabiso leentambo.

Ukuba ukhe wajonga intambo ye-SATA ukuya kwi-SATA ziyafana kwaye zifakwe intambo njenge-1: 1 intambo.Kwi-1: 1 intambo ye-pin 1 yesiphelo-A iya kwi-1 yesiphelo-B, i-pin 2 ukuya kwi-2, i-pin 3 ukuya kwi-3, njl. I-motherboard kunye ne-SATA yokudibanisa kwi-disk drive zibukeka zifana, kwaye ziyafana ngokwasemzimbeni, kodwa nganye ineentambo ezahlukeneyo.

Isidibanisi seSATA sinezikhonkwane ezisi-7.Izikhonkwane ezibini zenza iperi efunyenweyo kwaye ezimbini zezikhonkwane zenza iperi yokuhambisa.Ezinye izikhonkwane ezintathu zonke zisetyenziselwa iimpawu zomhlaba.Ukuba i-1: 1 ("ngqo-ngokusebenzisa") intambo ye-SATA ukuya kwi-SATA iza kusebenza, ngoko isibini esifumanayo asinakuba zizikhonkwane ezifanayo kwisidibaniso sesixhobo ngasinye (I-Host vs disk)!Ukuba bezizikhonkwane ezifanayo besiya kufuna into ebizwa ngokuba yintambo “yokuwela ngaphezulu”.Umgaqo othi "Absolute Rule" kukuba izikhonkwane zokuhambisa kwelinye icala kufuneka zidibanise kwizikhonkwane zokufumana kwelinye icala kwaye ngokufanayo.Oku kuyinyani kuqhagamshelo lwe-PC-PC RS232, uQhagamshelwano lwe-Ethernet, uqhagamshelo lwe-SATA, kwaye phantse zonke iintlobo zoqhagamshelo lwe-serial oluyi-duplex, oko kukuthi, ukwamkela nokuthumela iintambo ezahlukeneyo.

Zonke iziqhagamshelo ze-SAS zinezikhonkwane zazo ezicwangciswe ngendlela efanayo kungakhathaliseki ukuba zikwikhadi lolawulo lomkhosi, okanye i-backplane ye-SAS.Ekubeni kwizibuko ngalinye ezine ezenza i-SFF-8470 isidibanisi izikhonkwane zokuhambisa kunye nezikhonkwane zokufumana zikwindawo efanayo, kwaye kufuneka sidibanise ukuhanjiswa kwe-SAS kwi-SATA yamkela kwaye i-SAS ifumane kwi-SATA yokuhambisa (kwizibuko ngalinye);iintambo kufuneka zahluke ngokuxhomekeke ekubeni isidibanisi seSATA sikwidisk drive okanye iMotherboard/Host-Controller.

Intambo ye-SAS ukuya kwi-SAS kufuneka ke ngoko ibe yintambo “yokuwela ngapha” ukuqhagamshela izibini zokuhambisa zezibuko ukuya kwiiperi ezifumana izibuko ezihambelanayo kwelinye icala.
