Muaj peb hom kev sib txuas hluav taws xob rau 2.5-nti / 3.5-nti cov disks cia: PCIe, SAS thiab SATA, "Yav dhau los, kev txhim kho ntawm kev sib txuas lus ntawm cov chaw khaws ntaub ntawv tau tsav los ntawm IEEE lossis OIF-CEI cov koom haum lossis cov koom haum, thiab qhov tseeb niaj hnub no tau hloov pauv ntau heev. Cov neeg ua haujlwm hauv chaw khaws ntaub ntawv loj xws li Amazon, Apple, Facebook, Google, thiab Microsoft tab tom tsav cov thev naus laus zis, tsis tas yuav tos kom cov qauv ua tiav, tab sis rau tus neeg siv los hais txhua yam. Raws li kev ua tau zoo yav tom ntej ntawm PCIe SSD, SAS SSD thiab SATA SSD kev ua lag luam, qhia qhov kev kwv yees los ntawm Gartner rau txhua tus neeg siv thiab kev sib txuas lus.
Txog PCIe
PCIe yog qhov tsis muaj qhov tsis ntseeg tias yog tus qauv tsheb npav thauj neeg nrov tshaj plaws, thiab nws tau hloov kho tshiab ntau zaus 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 cov lus qhia tau ua tiav version 0.5, thiab muab rau cov tswv cuab ntawm lub koom haum, yuav raug tso tawm xyoo tom ntej raws sijhawm.
Txhua tsab ntawm PCIe specification mus dhau tsib qhov sib txawv / theem:
Version 0.3: Ib lub tswv yim ua ntej uas qhia txog cov yam ntxwv tseem ceeb thiab cov qauv ntawm cov lus qhia tshiab.
Version 0.5: Ib daim ntawv qauv pib uas qhia txog txhua yam ntawm cov qauv tshiab, suav nrog cov lus tawm tswv yim los ntawm cov tswv cuab ntawm lub koom haum raws li version 0.3, thiab suav nrog cov yam ntxwv tshiab uas cov tswv cuab thov ntxiv rau cov yam ntxwv tshiab.
Version 0.7: Daim qauv tiav lawm, txhua yam ntawm cov lus qhia tshiab tau txiav txim siab tag nrho, thiab cov lus qhia hluav taws xob kuj yuav tsum tau txheeb xyuas los ntawm lub chip sim. Yuav tsis muaj cov yam ntxwv tshiab ntxiv tom qab ntawd.
Version 0.9: Daim qauv kawg uas cov tswv cuab ntawm lub koom haum tuaj yeem tsim thiab txhim kho lawv cov thev naus laus zis thiab cov khoom lag luam.
Version 1.0: Kev tso tawm zaum kawg, kev tso tawm rau pej xeem.
Qhov tseeb, tom qab tso tawm version 0.5, cov chaw 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 tshwj xeeb. Thaum rov qab sib xws nrog PCIe 5.0/4.0/3.0/2.0/1.0, tus nqi ntaub ntawv lossis I/O bandwidth yuav ob npaug dua rau 64GT/s, thiab qhov tseeb unidirectional bandwidth ntawm PCIe 6.0 × 1 yog 8GB/s. PCIe 6.0 × 16 muaj 128GB/s hauv ib qho kev taw qhia thiab 256GB/s hauv ob qho kev taw qhia.
PCIe 6.0 yuav txuas ntxiv qhov 128b/130b encoding uas tau qhia hauv PCIe 3.0 era, tab sis ntxiv qhov tshiab pulse amplitude modulation PAM4 los hloov PCIe 5.0 NRZ, uas tuaj yeem ntim ntau cov ntaub ntawv hauv ib txoj channel hauv tib lub sijhawm, nrog rau kev kho qhov yuam kev qis latency (FEC) thiab cov txheej txheem cuam tshuam los txhim kho bandwidth efficiency.
Txog SAS
Serial Attached SCSI interface (SAS), SAS yog ib tiam tshiab ntawm SCSI technology, thiab cov nrov Serial ATA (SATA) hard disk zoo ib yam, yog siv cov serial technology kom tau txais kev sib kis ceev dua, thiab los ntawm kev luv cov kab txuas kom txhim kho qhov chaw sab hauv. SAS yog ib qho interface tshiab tsim tom qab parallel SCSI interface. Lub interface no yog tsim los txhim kho kev ua tau zoo, muaj, thiab scalability ntawm lub kaw lus cia, muab kev sib raug zoo nrog SATA hard drives. Lub SAS interface tsis yog zoo li SATA xwb, tab sis nws rov qab sib xws nrog tus qauv SATA. Lub Backpanel ntawm lub kaw lus SAS tuaj yeem txuas ob qho tib si dual-port, high-performance SAS drives thiab high-capacity, low-cost SATA drives. Yog li ntawd, SAS drives thiab SATA drives tuaj yeem nyob ua ke hauv tib lub kaw lus cia. Txawm li cas los xij, nws yuav tsum tau sau tseg tias SATA systems tsis sib xws SAS, yog li SAS drives tsis tuaj yeem txuas nrog SATA backplanes.
Piv nrog rau kev loj hlob zoo ntawm PCIe specification 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 rate tau raug tso tawm, thiab tiam tom ntej SAS 5.0 specification kuj tseem tab tom npaj, uas yuav ua rau tus nqi interface nce ntxiv mus rau 56Gbps.
Tam sim no, muaj ntau yam khoom tshiab, SAS interface SSD SSD tsawg heev, tus thawj coj kev siv internet hais tias cov neeg siv internet tsis tshua siv SAS SSD, vim yog qhov ua tau zoo ntawm tus nqi, SAS SSD ntawm PCIe thiab SATA SSD, txaj muag heev, kev ua tau zoo tsis tuaj yeem piv nrog PCIe. Cov chaw khaws ntaub ntawv loj heev xaiv PCIe, tus nqi tsis tuaj yeem tau txais SATA SSD, cov neeg siv khoom siv niaj hnub xaiv SATA SSD.
Txog SATA
SATA yog Serial ATA (Serial Advanced Technology Attachment), tseem hu ua Serial ATA, uas yog ib qho 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 txog cov zis sib txawv cov ntaub ntawv kab, sib xws, Rx +, Rx- qhia txog cov tswv yim sib txawv cov ntaub ntawv kab, raws li feem ntau siv hard disk interface hauv kev ua lag luam, 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, qhov theoretical kis bandwidth ntawm 6Gbps, txawm hais tias piv nrog lub interface tshiab ntawm 10Gbps thiab 32Gbps bandwidth muaj qee qhov sib txawv, tab sis ordinary 2.5-nti SSD tuaj yeem ua tau raws li cov kev xav tau txhua hnub ntawm cov neeg siv feem ntau, 500MB / s lossis li ntawd nyeem thiab sau ceev txaus.
