Kunezinhlobo ezintathu zokuxhumana zikagesi zamadiski okugcina angu-2.5-intshi / 3.5-intshi: i-PCIe, i-SAS ne-SATA, “Phambilini, ukuthuthukiswa kokuxhumana kwesikhungo sedatha empeleni kwakuqhutshwa izikhungo noma izinhlangano ze-IEEE noma ze-OIF-CEI, futhi iqiniso namuhla lishintshe kakhulu.Ama-opharetha amakhulu esikhungo sedatha afana ne-Amazon, i-Apple, i-Facebook, i-Google, ne-Microsoft bashayela ubuchwepheshe, hhayi ukuthi balinde ukuthi kuqedwe amazinga, kodwa ukuze umsebenzisi anqume yonke into.Ngokuqondene nokusebenza kwesikhathi esizayo kwemakethe ye-PCIe SSD, SAS SSD kanye ne-SATA SSD, yabelana ngesibikezelo esenziwe ngu-Gartner ukuze kusetshenziswe ireferensi nokuxhumana kwawo wonke umuntu.
Mayelana ne-PCIe
I-PCIe ngokungangabazeki iyindinganiso yamabhasi ezokuthutha ethandwa kakhulu, futhi ibuyekezwa kaningi eminyakeni yamuva: I-PCIe 3.0 isathandwa kakhulu, i-PCIe 4.0 ikhuphuka ngokushesha, i-PCIe 5.0 isizohlangana nawe, ukucaciswa kwe-PCIe 6.0 sekuqediwe inguqulo engu-0.5 , futhi inikezwe amalungu enhlangano, izokhishwa ngonyaka ozayo ngohlelo lokugcina olusemthethweni.
Uhlelo ngalunye lokucaciswa kwe-PCIe ludlula ezinhlotsheni/izigaba ezinhlanu ezahlukene:
Inguqulo engu-0.3: Umqondo wokuqala owethula izici ezibalulekile nezakhiwo zencazelo entsha.
Inguqulo engu-0.5: Ukucaciswa kokuqala okusalungiswa okukhomba zonke izici zesakhiwo esisha, kuhlanganisa impendulo evela kumalungu enhlangano ngokusekelwe kunguqulo 0.3, futhi kuhlanganisa izici ezintsha ezicelwe amalungu kanye nezici ezintsha.
Inguqulo engu-0.7: Okusalungiswa okuphelele, zonke izici zokucaciswa okusha zinqunywa ngokugcwele, futhi imininingwane kagesi kufanele futhi iqinisekiswe yi-chip yokuhlola.Azikho izici ezintsha ezizongezwa ngemva kwalokho.
Inguqulo 0.9: Okusalungiswa kokugcina lapho amalungu enhlangano angaklama futhi athuthukise eyawo ubuchwepheshe nemikhiqizo.
Inguqulo 1.0: Ukukhishwa okusemthethweni kokugcina, ukukhululwa esidlangalaleni.
Eqinisweni, ngemuva kokukhishwa kwenguqulo 0.5, abakhiqizi sebengaqala ukuklama ama-chip chips ukuze balungiselele umsebenzi olandelayo kusenesikhathi.
I-PCIe 6.0 injalo.Uma ubuyela emuva uhambisana ne-PCIe 5.0/4.0/3.0/2.0/1.0, isilinganiso sedatha noma umkhawulokudonsa we-I/O uzophinda kabili futhi ube ngu-64GT/s, futhi umkhawulokudonsa wangempela we-PCIe 6.0×1 wangempela ngu-8GB/s.I-PCIe 6.0×16 ino-128GB/s ohlangothini olulodwa kanye no-256GB/s kuzo zombili izinkomba.
I-PCIe 6.0 izoqhubeka nombhalo wekhodi we-128b/130b owethulwe esikhathini se-PCIe 3.0, kodwa yengeze i-pulse amplitude module entsha i-PAM4 ukuze ithathe indawo ye-PCIe 5.0 NRZ, engapakisha idatha eyengeziwe esiteshini esisodwa ngesikhathi esifanayo, kanye nephansi. ukulungiswa kwephutha le-latency forward (FEC) kanye nezindlela ezihlobene zokuthuthukisa ukusebenza kahle komkhawulokudonsa.
Mayelana ne-SAS
I-Serial Attached SCSI interface (SAS), i-SAS isizukulwane esisha sobuchwepheshe be-SCSI, futhi i-hard disk edumile ye-Serial ATA(SATA) iyafana, ukusetshenziswa kobuchwepheshe be-serial ukuthola isivinini sokudlulisa esiphezulu, futhi ngokunciphisa ulayini wokuxhuma ku ngcono indawo yangaphakathi.I-SAS iyisixhumi esibonakalayo esisha esakhiwe ngemva kwesixhumi esibonakalayo se-SCSI esihambisanayo.Lesi sixhumanisi siklanyelwe ukuthuthukisa ukusebenza, ukutholakala, kanye nokulinganisa kwesistimu yokugcina, ukuhlinzeka ngokuhambisana namadrayivu aqinile e-SATA.I-interface ye-SAS ayibukeki njenge-SATA kuphela, kodwa ibuyela emuva iyahambisana nezinga le-SATA.I-Backpanel yohlelo lwe-SAS ingaxhuma kokubili amachweba amabili, amadrayivu e-SAS asebenza kahle kakhulu kanye nomthamo ophezulu, amadrayivu e-SATA angabizi kakhulu.Ngenxa yalokho, amadrayivu e-SAS namadrayivu e-SATA angahlala ndawonye ohlelweni olufanayo lokulondoloza.Kodwa-ke, kufanele kuqashelwe ukuthi izinhlelo ze-SATA azihambisani ne-SAS, ngakho-ke amadrayivu e-SAS awakwazi ukuxhunywa ezindizeni ezingemuva ze-SATA.
Uma kuqhathaniswa nokuthuthuka okukhulu kokucaciswa kwe-PCIe eminyakeni yamuva nje, ukucaciswa kwe-SAS kuye kwavela kancane kancane, kwathi ngoNovemba 2019, ukucaciswa kwe-SAS 4.1 kusetshenziswa isilinganiso se-interface engu-24Gbps kwakhululwa ngokusemthethweni, kanye nokucaciswa kwe-SAS 5.0 kwesizukulwane esilandelayo nakho kungaphakathi. ukulungiselela, okuzoqhubeza nokwenyusa izinga lokuxhumana libe ngu-56Gbps.
Njengamanje, emikhiqizweni eminingi emisha, i-SAS interface ye-SSD SSD imbalwa kakhulu, umqondisi wezobuchwepheshe wabasebenzisi be-inthanethi uthe abasebenzisi be-inthanethi abavamile ukusebenzisa i-SAS SSD, ikakhulukazi ngenxa yezizathu zokusebenza kwezindleko, i-SAS SSD phakathi kwe-PCIe ne-SATA SSD, ihlazo kakhulu, ukusebenza ingafaniswa ne-PCIe.Izikhungo zedatha ezinkulu kakhulu zikhetha i-PCIe, intengo ayikwazi ukuthola i-SATA SSD, amakhasimende avamile abathengi akhetha i-SATA SSD.
Mayelana ne-SATA
I-SATA iyi-Serial ATA (I-Serial Advanced Technology Attachment), eyaziwa nangokuthi i-Serial ATA, okuwuhlelo lokucaciswa kwe-hard disk interface ehlongozwe ngokuhlanganyela yi-Intel, i-IBM, i-Dell, i-APT, i-Maxtor, ne-Seagate.
I-interface ye-SATA isebenzisa izintambo ezingu-4 ukudlulisa idatha, isakhiwo sayo silula, i-Tx+, i-Tx- ikhombisa umugqa wedatha wokuhluka okukhiphayo, ohambisanayo, i-Rx+, i-Rx- ikhombisa umugqa wedatha wokuhlukanisa okokufaka, njengesikhombimsebenzisi esisetshenziswa kakhulu se-hard disk emakethe, inguqulo yamanje edumile yi-3.0, inzuzo enkulu ye-SATA 3.0 interface kufanele ibe evuthiwe, i-SSD Ejwayelekile engu-2.5-intshi kanye nama-hard disks e-HDD asebenzisa lesi sikhombimsebenzisi, umkhawulokudonsa wokudluliswa kwethiyori we-6Gbps, nakuba uqhathaniswa ne-interface entsha ye-10Gbps kanye ne-32Gbps yomkhawulokudonsa lapho. iyigebe elithile, kodwa i-SSD evamile engu-2.5-intshi ingahlangabezana nezidingo zohlelo lokusebenza zansuku zonke zabasebenzisi abaningi, 500MB/s noma isivinini sokufunda nokubhala sanele.
