Kune marudzi matatu emagetsi ekubatanidza e2.5-inch / 3.5-inch ekuchengetedza disks: PCIe, SAS uye SATA, "Kare, kuvandudzwa kwedata center interconnection kwaifambiswa neIEEE kana OIF-CEI masangano kana masangano, uye nhasi zvachinja zvakanyanya. raira zvese nezve ramangwana rePCIe SSD,SAS SSD uye SATA SSD musika, govana fungidziro yakaitwa naGartner kune wese munhu kutaurwa 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 tsanangudzo yapedzwa vhezheni 0.5, uye yakapihwa kunhengo dzesangano gore rinouya, vhezheni yekupedzisira ichaburitswa.
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 zvichienderana neshanduro 0.3, uye inosanganisira zvitsva zvinokumbirwa nenhengo pamwe nemaitiro matsva.
Shanduro 0.7: Yakazara dhizaini, ese maficha eiyo nyowani 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 che data kana I/O bandwidth ichapeta zvakare ku64GT/s, uye iyo chaiyo unidirectional bandwidth yePCIe 6.0 × 1 ndeye 8GB/s. PCIe 6.0 × 16 ine 128GB/s munzira imwe uye 256GB/s mumativi ese.
PCIe 6.0 ichaenderera mberi ne128b / 130b encoding yakaunzwa munguva yePCIe 3.0, asi wedzera imwe pulse amplitude modulation PAM4 kutsiva PCIe 5.0 NRZ, iyo inogona kurongedza data rakawanda muchiteshi chimwe munguva imwe chete yenguva, pamwe chete nechepasi latency yemberi yekukanganisa kugadzirisa uye kugadzirisa bandwidth kune hukama.
About SAS
Serial Attached SCSI interface (SAS), SAS chizvarwa chitsva cheSCSI tekinoroji, uye yakakurumbira Serial ATA (SATA) hard disk yakafanana, iko kushandiswa kweiyo serial tekinoroji kuwana yakakwirira yekufambisa kumhanya, uye nekupfupisa tambo yekubatanidza kuvandudza 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, uye muna Mbudzi 2019, iyo SAS 4.1 yakatarwa ichishandisa 24Gbps interface rate yakaburitswa zviri pamutemo, uye chizvarwa chinotevera SAS 5.0 kutsanangurwa kuri mukugadzirira, izvo zvichawedzera kuwedzera chiyero chechimiro kusvika ku56Gbps.
Parizvino, muzvigadzirwa zvitsva zvakawanda, SAS interface SSD SSD ishoma kwazvo, maneja weInternet mushandisi wehunyanzvi akataura kuti vashandisi veInternet havawanzo shandisa SAS SSD, kunyanya nekuda kwezvikonzero zvekuita kwemitengo, SAS SSD pakati pePCIe neSATA SSD, inonyadzisa, kuita hakugone 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 yakatsanangurwa yakabatanidzwa neIntel, IBM, Dell, APT, Maxtor, uye Seagate.
SATA interface inoshandisa tambo 4 kutumira 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, iyo yazvino yakakurumbira vhezheni ndeye 3.0, iyo yakakura mukana weSATA 3.0 interface inofanira kunge yakakura, 5-inch hard disk dhisiki shandisa HDD 2. transmission bandwidth ye6Gbps, kunyangwe ichienzaniswa neiyo nyowani interface ye10Gbps uye 32Gbps bandwidth pane imwe gap, asi yakajairwa 2.5-inch SSD inogona kusangana nezvinodiwa zvezuva nezuva zvevashandisi vazhinji, 500MB/s kana kuti kuverenga nekunyora kumhanya kwakakwana.
