Muaj peb hom hluav taws xob sib cuam tshuam rau 2.5-nti / 3.5-nti cia disks: PCIe, SAS thiab SATA, "Thaum yav dhau los, kev txhim kho cov ntaub ntawv chaw sib cuam tshuam tau tsav los ntawm IEEE lossis OIF-CEI cov koom haum lossis koom haum, thiab hauv qhov tseeb niaj hnub no tau hloov pauv loj heev.Cov neeg ua haujlwm loj cov ntaub ntawv xws li Amazon, Apple, Facebook, Google, thiab Microsoft tab tom tsav lub thev naus laus zis, tsis tas tos cov qauv ua kom tiav, tab sis rau cov neeg siv los txiav txim txhua yam.Raws li rau yav tom ntej kev ua tau zoo ntawm PCIe SSD, SAS SSD thiab SATA SSD kev ua lag luam, qhia txog kev kwv yees ua los ntawm Gartner rau txhua tus neeg siv thiab kev sib txuas lus.
Hais txog PCIe
PCIe yog undoubtedly tus qauv tsheb thauj neeg nrov tshaj plaws, thiab nws tau raug hloov kho tas li nyob rau hauv xyoo tas los no: PCIe 3.0 tseem yog qhov nrov tshaj plaws, PCIe 4.0 tab tom nce sai, PCIe 5.0 tab tom yuav ntsib koj, PCIe 6.0 specification tau ua tiav version 0.5. , thiab muab rau cov tswv cuab ntawm lub koom haum, yuav raug tso tawm xyoo tom ntej raws li lub sijhawm kawg official version.
Txhua tsab ntawm PCIe specification mus dhau tsib qhov sib txawv / theem:
Version 0.3: Lub tswv yim ua ntej uas nthuav tawm cov yam ntxwv tseem ceeb thiab kev tsim qauv ntawm cov lus qhia tshiab.
Version 0.5: Thawj qhov kev qhia tshwj xeeb uas txheeb xyuas txhua yam ntawm cov qauv tshiab, suav nrog kev tawm tswv yim los ntawm cov tswv cuab hauv lub koom haum raws li version 0.3, thiab suav nrog cov yam ntxwv tshiab thov los ntawm cov tswv cuab ntxiv rau cov yam ntxwv tshiab.
Version 0.7: Ua tiav cov qauv, txhua yam ntawm cov lus qhia tshiab tau txiav txim siab tag nrho, thiab cov lus qhia hluav taws xob kuj tseem yuav tsum tau txheeb xyuas los ntawm cov nti ntsuas.Tsis muaj cov yam ntxwv tshiab yuav ntxiv tom qab ntawd.
Version 0.9: Cov qauv kawg uas cov tswv cuab tuaj yeem tsim thiab tsim lawv tus kheej thev naus laus zis thiab cov khoom lag luam.
Version 1.0: Qhov kawg tso tawm, tshaj tawm rau pej xeem.
Qhov tseeb, tom qab kev tso tawm ntawm version 0.5, cov tuam txhab tsim khoom tuaj yeem pib tsim cov chips sim los npaj rau kev ua haujlwm tom ntej ua ntej.
PCIe 6.0 tsis muaj qhov zam.Thaum rov qab tau tshaj PCIe 5.0 / 4.0 / 3.0 / 2.0 / 1.0, cov ntaub ntawv tus nqi lossis I / O bandwidth yuav muab ob npaug rau 64GT / s, thiab qhov tseeb unidirectional bandwidth ntawm PCIe 6.0 × 1 yog 8GB / s.PCIe 6.0 × 16 muaj 128GB / s nyob rau hauv ib qho kev taw qhia thiab 256GB / s nyob rau hauv ob qho tib si qhia.
PCIe 6.0 yuav txuas ntxiv 128b / 130b encoding qhia nyob rau hauv PCIe 3.0 era, tab sis ntxiv ib qho tshiab pulse amplitude modulation PAM4 los hloov PCIe 5.0 NRZ, uas tuaj yeem ntim cov ntaub ntawv ntau dua hauv ib qho channel hauv tib lub sijhawm, nrog rau qis. latency forward error kho (FEC) thiab lwm yam mechanisms los txhim kho bandwidth efficiency.
Hais txog SAS
Serial Attached SCSI interface (SAS), SAS yog lub cim tshiab ntawm SCSI thev naus laus zis, thiab nrov Serial ATA (SATA) hard disk yog tib yam, yog kev siv cov thev naus laus zis kom tau txais kev sib kis ceev dua, thiab los ntawm kev luv luv ntawm cov kab txuas mus rau txhim kho qhov chaw sab hauv.SAS yog qhov tshiab interface tsim tom qab qhov sib npaug SCSI interface.Qhov no interface yog tsim los txhim kho cov kev ua tau zoo, muaj, thiab scalability ntawm lub cia system, muab compatibility nrog SATA hard drives.SAS interface tsis tsuas yog zoo ib yam li SATA, tab sis rov qab sib xws nrog SATA tus qauv.Lub Backpanel ntawm SAS system tuaj yeem txuas ob qhov chaw nres nkoj dual, kev ua haujlwm siab SAS tsav thiab muaj peev xwm siab, tus nqi qis SATA tsav.Yog li ntawd, SAS drives thiab SATA drives tuaj yeem koom ua ke hauv tib lub kaw lus cia.Txawm li cas los xij, nws yuav tsum raug sau tseg tias SATA systems tsis yog SAS tshaj, yog li SAS drives tsis tuaj yeem txuas nrog SATA backplanes.
Piv nrog rau txoj kev loj hlob ntawm kev loj hlob ntawm PCIe specification nyob rau hauv xyoo tas los no, SAS specification tau maj mam hloov zuj zus mus ntsiag to, thiab thaum lub Kaum Ib Hlis 2019, SAS 4.1 specification siv 24Gbps interface tus nqi tau raug tso tawm, thiab cov tiam tom ntej SAS 5.0 specification kuj tseem nyob rau hauv. kev npaj, uas yuav ntxiv qhov sib txuas tus nqi mus rau 56Gbps.
Tam sim no, nyob rau hauv ntau yam khoom tshiab, SAS interface SSD SSD muaj tsawg heev, tus neeg siv Is Taws Nem tus thawj coj ua haujlwm tau hais tias cov neeg siv Is Taws Nem tsis tshua siv SAS SSD, feem ntau yog vim li cas tus nqi ua haujlwm, SAS SSD ntawm PCIe thiab SATA SSD, txaj muag heev, kev ua tau zoo tuaj yeem ua tau. tsis muab piv nrog PCIe.Ultra-loj cov ntaub ntawv chaw xaiv PCIe, tus nqi tsis tuaj yeem tau txais SATA SSD, cov neeg siv khoom zoo tib yam xaiv SATA SSD.
Hais txog SATA
SATA yog Serial ATA (Serial Advanced Technology Attachment), tseem hu ua Serial ATA, uas yog lub hard disk interface specification ua ke los ntawm Intel, IBM, Dell, APT, Maxtor, thiab Seagate.
SATA interface siv 4 cables los xa cov ntaub ntawv, nws cov qauv yog yooj yim, Tx +, Tx- qhia cov zis sib txawv cov ntaub ntawv kab, sib xws, Rx +, Rx- qhia cov tswv yim sib txawv cov ntaub ntawv kab, raws li kev siv ntau tshaj plaws hard disk interface hauv khw, Tam sim no nrov version yog 3.0, qhov zoo tshaj plaws ntawm SATA 3.0 interface yuav tsum paub tab, Ordinary 2.5-nti SSD thiab HDD hard disks siv qhov interface no, theoretical transmission bandwidth ntawm 6Gbps, txawm hais tias piv nrog lub interface tshiab ntawm 10Gbps thiab 32Gbps bandwidth muaj. yog qhov sib txawv, tab sis qhov zoo tib yam 2.5-nti SSD tuaj yeem ua tau raws li qhov xav tau ntawm daim ntawv thov txhua hnub ntawm cov neeg siv feem ntau, 500MB / s lossis yog li nyeem thiab sau nrawm txaus.
