Kukho iintlobo ezintathu zonxibelelwano lombane lwe-2.5-intshi / i-3.5-intshi yokugcina iidiski: i-PCIe, i-SAS kunye ne-SATA, "Kwixesha elidlulileyo, uphuhliso lonxibelelwano lweziko ledatha lwaluqhutywa yi-IEEE okanye ngamaziko e-OIF-CEI okanye imibutho, kwaye eneneni namhlanje itshintshe kakhulu. Yalela yonke into malunga nokusebenza kwexesha elizayo kwePCIe SSD, SAS SSD kunye neSATA SSD yentengiso, yabelana ngengqikelelo eyenziwe nguGartner kwireferensi yomntu wonke kunye nonxibelelwano.
Malunga PCIe
I-PCIe ngokungathandabuzekiyo ngowona mgangatho webhasi yezothutho uthandwa kakhulu, kwaye ihlaziywe rhoqo kwiminyaka yakutshanje: I-PCIe 3.0 iseyeyona idumileyo, i-PCIe 4.0 iyenyuka ngokukhawuleza, i-PCIe 5.0 iza kudibana nawe, iinkcukacha ze-PCIe 6.0 zigqityiwe uguqulelo 0.5, kwaye lunikezelwe kumalungu ombutho kunyaka olandelayo kwishedyuli, iya kukhutshwa ngokusemthethweni.
Uhlelo ngalunye lwenkcazo ye-PCIe luhamba ngeenguqulelo/izigaba ezintlanu ezahlukeneyo:
Inguqulo 0.3: Ingqikelelo yokuqala ebonisa iimpawu eziphambili kunye noyilo lwenkcazo entsha.
Inguqulo ye-0.5: Inkcazo yokuqala eyidrafti echonga yonke imiba yolwakhiwo olutsha, ibandakanya impendulo evela kumalungu ombutho ngokusekelwe kwinguqulo ye-0.3, kwaye ibandakanya izinto ezintsha ezicelwe ngamalungu kunye neempawu ezintsha.
Inguqulo ye-0.7: Idrafti epheleleyo, yonke imiba yenkcazo entsha inqunywe ngokupheleleyo, kwaye ukucaciswa kombane kufuneka kwakhona kuqinisekiswe yi-chip chip. Akukho zinto zintsha ziya kongezwa emva koko.
Inguqulelo 0.9: Idrafti yokugqibela apho amalungu ombutho anokuyila kwaye aphuhlise itekhnoloji kunye neemveliso zabo.
Inguqulo ye-1.0: Ukukhutshwa okusemthethweni kokugqibela, ukukhululwa koluntu.
Enyanisweni, emva kokukhululwa kwenguqulo ye-0.5, abavelisi banokuqala ukuyila iitshiphusi zokuvavanya ukulungiselela umsebenzi olandelayo kwangaphambili.
PCIe 6.0 akukho ngaphandle. Xa umva uhambelana ne-PCIe 5.0/4.0/3.0/2.0/1.0, ireyithi yedatha okanye i-I/O bandwidth iya kuphinda kabini kwakhona kwi-64GT/s, kunye ne-bandwidth yangempela ye-PCIe 6.0 × 1 yi-8GB / s. I-PCIe 6.0×16 ine-128GB/s kwicala elinye kunye ne-256GB/s macala omabini.
I-PCIe 6.0 iya kuqhubeka ne-128b / 130b encoding eqaliswe kwixesha le-PCIe 3.0, kodwa yongeza i-pulse amplitude modulation entsha ye-PAM4 ukuze ithathe indawo ye-PCIe 5.0 NRZ, engakwazi ukupakisha idatha eninzi kwitshaneli enye ngexesha elifanayo, kunye ne-low latency forward correction correction (FEC) kunye nokulungiswa kwempazamo ehambelanayo ne-FEC.
Malunga ne-SAS
Uthotho Iqhotyoshelwe SCSI ujongano (SAS), SAS sisizukulwana esitsha sobuchwepheshe SCSI, kunye ethandwayo Serial ATA (SATA) hard disk iyafana, kukusetyenziswa kobuchwephesha serial ukufumana isantya transmission eliphezulu, kwaye ngokunciphisa umgca uqhagamshelwano ukuphucula indawo yangaphakathi. I-SAS lujongano olutsha oluphuhliswe emva kojongano olunxuseneyo lwe-SCSI. Olu jongano lwenzelwe ukuphucula ukusebenza, ukufumaneka, kunye ne-scalability yenkqubo yokugcina, ukubonelela ngokuhambelana ne-SATA hard drives. I-interface ye-SAS ayibonakali nje ngokufana ne-SATA, kodwa ibuyela ngasemva iyahambelana nomgangatho we-SATA. I-Backpanel yenkqubo ye-SAS inokudibanisa zombini i-port-port, i-high-performance SAS drives kunye ne-high-capacity, i-SATA yexabiso eliphantsi. Ngenxa yoko, ii-SAS drives kunye ne-SATA drives zinokuhlalisana kwinkqubo efanayo yokugcina. Nangona kunjalo, kufuneka kuqatshelwe ukuba iinkqubo ze-SATA azihambelani ne-SAS, ngoko ke iidrive ze-SAS azikwazi ukuqhagamshelwa kwii-backplanes ze-SATA.
Xa kuthelekiswa nophuhliso olukhulu lwePCIe kwiminyaka yakutshanje, ukucaciswa kwe-SAS kuye kwavela ngokuthe ngcembe, kwaye ngoNovemba ka-2019, ukucaciswa kwe-SAS 4.1 kusetyenziswa ireyithi ye-interface ye-24Gbps yakhululwa ngokusemthethweni, kwaye isizukulwana esilandelayo i-SAS 5.0 inkcazo ikwilungiselelo, eliya kwandisa ngakumbi ireyithi ye-interface ukuya kwi-56Gbps.
Okwangoku, kwiimveliso ezininzi ezintsha, i-SAS interface ye-SSD ye-SSD imbalwa kakhulu, umlawuli wobugcisa bomsebenzisi we-Intanethi wathi abasebenzisi be-Intanethi abafane basebenzise i-SAS SSD, ikakhulu ngenxa yezizathu zokusebenza kweendleko, i-SAS SSD phakathi kwe-PCIe kunye ne-SATA SSD, ihlazo kakhulu, ukusebenza akunakuthelekiswa ne-PCIe. Amaziko edatha amakhulu kakhulu akhetha i-PCIe, ixabiso alikwazi ukufumana i-SATA SSD, abathengi abaqhelekileyo abathengi bakhetha i-SATA SSD.
Malunga neSATA
I-SATA yi-Serial ATA (i-Serial Advanced Technology Attachment), ekwabizwa ngokuba yi-Serial ATA, eyinkcazo yojongano lwediski enzima ecetywe ngokudibeneyo yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor, kunye ne-Seagate.
Ujongano lwe-SATA lusebenzisa iintambo ezi-4 ukuhambisa idatha, ubume bayo bulula, i-Tx +, i-Tx- ibonisa umgca wedatha yokwahlukana kwemveliso, ehambelanayo, i-Rx +, i-Rx- ibonisa igalelo lomgca wedatha yedatha, njengoko i-hard disk interface esetyenziswa kakhulu kwimarike, inguqulo yangoku ethandwayo yi-3.0, inzuzo enkulu ye-SATA 3.0 ujongano kufuneka ibe ivuthiwe, i-disk ye-intshi ye-5-intshi ye-SSD2. ukuhanjiswa kwe-bandwidth ye-6Gbps, nangona kuthelekiswa ne-interface entsha ye-10Gbps kunye ne-32Gbps bandwidth kukho i-gap ethile, kodwa i-SSD eqhelekileyo ye-2.5-intshi inokuhlangabezana neemfuno zesicelo semihla ngemihla yabasebenzisi abaninzi, i-500MB / s okanye isantya sokufunda nokubhala sanele.
