Kune marudzi matatu emagetsi ekubatanidza 2.5-inch / 3.5-inch ekuchengetedza disks: PCIe, SAS uye SATA, "Kare, kuvandudzwa kwedata center interconnection kwaifambiswa neIEEE kana OIF-CEI masangano kana masangano, uye mu chokwadi nhasi chachinja zvakanyanya.Big data center vanoshanda seAmazon, Apple, Facebook, Google, uye Microsoft vari kutyaira tekinoroji, kwete hazvo kumirira kuti zviyero zvipedzwe, asi kuti mushandisi ataure zvese.Kana iri remangwana rekuita kwePCIe SSD,SAS SSD uye SATA SSD musika, govana fungidziro yakaitwa naGartner yereferensi yemunhu wese uye kutaurirana.
About PCIe
PCIe pasina mubvunzo ndiyo inonyanya kufarirwa bhazi mwero, uye yakagadziridzwa kazhinji mumakore achangopfuura: PCIe 3.0 ichiri kufarirwa zvakanyanya, PCIe 4.0 iri kusimuka nekukurumidza, PCIe 5.0 yave kuda kusangana newe, PCIe 6.0 yakatarwa yapedzwa vhezheni 0.5. , uye yakapihwa nhengo dzesangano, ichaburitswa gore rinouya pane yakarongwa yekupedzisira shanduro yepamutemo.
Imwe neimwe edition yePCIe yakatarwa inoenda kuburikidza neshanu dzakasiyana shanduro / nhanho:
vhezheni 0.3: Yekutanga pfungwa inopa akakosha maficha uye magadzirirwo eiyo nyowani yakatarwa.
Shanduro 0.5: Yekutanga dhizaini inotaridza zvese zvikamu zvechivako chitsva, inosanganisira mhinduro kubva kunhengo dzesangano zvinoenderana neshanduro 0.3, uye inosanganisira zvitsva zvinokumbirwa nenhengo pamwe nemaitiro matsva.
Shanduro 0.7: Yakazara dhizaini, ese maficha eiyo nyowani yakatarwa akatemerwa zvizere, uye iyo yemagetsi dhizaini inofanirwawo kusimbiswa neiyo test chip.Hapana zvitsva zvichawedzerwa mushure mezvo.
vhezheni 0.9: Yekupedzisira dhizaini kubva kune iyo nhengo dzesangano dzinogona kugadzira uye kugadzira yavo tekinoroji uye zvigadzirwa.
Shanduro 1.0: Yekupedzisira kuburitswa kwepamutemo, kuburitswa pachena.
Muchokwadi, mushure mekuburitswa kwevhezheni 0.5, vagadziri vanogona kutotanga kugadzira machipisi ekuyedza kugadzirira basa rinotevera pamberi.
PCIe 6.0 haina mutsauko.Kana kumashure kunoenderana nePCIe 5.0/4.0/3.0/2.0/1.0, chiyero chedata kana I/O bandwidth ichapeta zvakare ku64GT/s, uye iyo chaiyo unidirectional bandwidth yePCIe 6.0 × 1 i8GB/s.PCIe 6.0 × 16 ine 128GB/s munzira imwe uye 256GB/s mumativi ese.
PCIe 6.0 ichaenderera mberi neiyo 128b/130b encoding yakaunzwa munguva yePCIe 3.0, asi wedzera imwe pulse amplitude modulation PAM4 kutsiva PCIe 5.0 NRZ, inogona kurongedza data rakawanda muchiteshi chimwe chete munguva imwe chete yenguva, pamwe neyakaderera. latency mberi kukanganisa kururamisa (FEC) uye nzira dzakabatana dzekuvandudza bandwidth kushanda.
About SAS
Serial Attached SCSI interface (SAS), SAS chizvarwa chitsva cheSCSI tekinoroji, uye yakakurumbira Serial ATA (SATA) hard disk yakafanana, iko kushandiswa kweserial tekinoroji kuwana kukurumidza kwekufambisa, uye nekupfupisa tambo yekubatanidza kusvika. vandudza nzvimbo yemukati.SAS iratidziro nyowani yakagadziridzwa mushure meiyo yakafanana SCSI interface.Iyi interface yakagadzirirwa kuvandudza mashandiro, kuwanikwa, uye scalability yegadziriro yekuchengetedza, ichipa kuenderana neSATA hard drives.Iyo SAS interface haingotaridzi yakafanana neSATA, asi inodzokera kumashure inoenderana neSATA standard.Iyo Backpanel yeSAS system inogona kubatanidza ese ari maviri-chiteshi, akakwira-kuita SAS madhiraivha uye yakakwirira-chaiyo, yakaderera-mutengo SATA madhiraivha.Nekuda kweizvozvo, madhiraivha eSAS uye maSATA anogona kugarisana mune imwechete yekuchengetedza system.Nekudaro, zvinofanirwa kucherechedzwa kuti maSATA masisitimu haaenderane neSAS, saka madhiraivha eSAS haagone kubatana neSATA backplanes.
Zvichienzaniswa nekukura kukuru kwekusimudzira kwePCIe yakatarwa mumakore achangopfuura, iyo SAS yakatarwa yakashanduka zvishoma nezvishoma chinyararire, uye muna Mbudzi 2019, iyo SAS 4.1 yakatarwa ichishandisa 24Gbps interface rate yakaburitswa zviri pamutemo, uye chizvarwa chinotevera SAS 5.0 yakatarwa zvakare irimo kugadzirira, izvo zvichawedzera kuwedzera chiyero chechimiro kusvika ku56Gbps.
Parizvino, muzvigadzirwa zvitsva zvakawanda, SAS interface SSD SSD ishoma kwazvo, maneja weInternet mushandisi akataura kuti vashandisi veInternet havawanzo shandisa SAS SSD, kunyanya nekuda kwezvikonzero zvekuita mutengo, SAS SSD pakati pePCIe neSATA SSD, inonyadzisa, kuita kunogona. kwete kuenzaniswa nePCIe.Ultra-hombe dhata nzvimbo dzinosarudza PCIe, mutengo haugone kuwana SATA SSD, vatengi vese vatengi vanosarudza SATA SSD.
Pamusoro peSATA
SATA ndeye Serial ATA (Serial Advanced Technology Attachment), inozivikanwawo seSeri ATA, inova yakaoma dhisiki interface yakabatana yakakurudzirwa neIntel, IBM, Dell, APT, Maxtor, uye Seagate.
SATA interface inoshandisa 4 tambo kuendesa data, chimiro chayo chiri nyore, Tx +, Tx- inoratidza yakabuda mutsara wedhata mutsara, inoenderana, Rx +, Rx- inoratidza iyo yekuisa yekusiyanisa data mutsara, seyakanyanya kushandiswa hard disk interface mumusika, yazvino yakakurumbira vhezheni ndeye 3.0, iyo yakakura mukana weSATA 3.0 interface inofanira kunge yakakura, Ordinary 2.5-inch SSD uye HDD hard disks vanoshandisa iyi interface, theoretical transmission bandwidth ye6Gbps, kunyangwe ichienzaniswa neiyo nyowani interface ye10Gbps uye 32Gbps bandwidth ipapo. imwe gap, asi yakajairwa 2.5-inch SSD inogona kusangana nezvinodiwa zvemazuva ese zvevashandisi vazhinji, 500MB/s kana kuverenga nekunyora kumhanya kwakakwana.
