PCIe vs SAS vs SATA: Sib ntaus sib tua ntawm Next-Generation Storage Interface Technologies

Tam sim no, 2.5-nti / 3.5-nti cia hard disks hauv kev lag luam feem ntau muaj peb qhov sib cuam tshuam: PCIe, SAS thiab SATA. Hauv cov ntaub ntawv chaw siv, kev sib txuas daws teeb meem xws li MINI SAS 8087 rau 4X SATA 7P Txiv neej cable thiab MINI SAS 8087 rau SLIM SAS 8654 4I tau dav siv. Yav dhau los, kev txhim kho ntawm cov ntaub ntawv chaw sib txuas hloov kho tshiab tau raug tsav los ntawm cov koom haum lossis cov koom haum xws li IEEE lossis OIF-CEI. Txawm li cas los xij, muaj kev hloov pauv tseem ceeb tau tshwm sim tam sim no. Cov neeg ua haujlwm loj cov ntaub ntawv xws li Amazon, Apple, Facebook, Google thiab Microsoft tam sim no tau tsav kev tsim kho thev naus laus zis.

Hais txog PCIe

PCIe yog undoubtedly tus qauv tsheb npav nrov tshaj plaws, thiab nws cov kev hloov tshiab tau nquag heev nyob rau xyoo tas los no. Txawm hais tias qhov kev hloov kho ceev tau nrawm dua, cov kev hloov pauv hauv txhua tiam ntawm PCIe specification yog qhov tseem ceeb, tshwj xeeb tshaj yog nrog cov bandwidth ob zaug txhua lub sijhawm thiab tswj kev sib raug zoo nrog txhua tiam dhau los.

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 64 GT / s. Qhov tseeb ib-txoj kev bandwidth ntawm PCIe 6.0 x1 yog 8 GB / s, ib-txoj kev bandwidth ntawm PCIe 6.0 x16 yog 128 GB / s, thiab lub bidirectional bandwidth yog 256 GB / s. Qhov kev kub ceev no kuj tau ua rau cov kev sib txuas tshiab xws li MCIO 8I mus rau 2 OCuLink 4i cable, PCIe Slimline SAS 4.0 38-Pin SFF-8654 4i rau 4 SATA 7-Pin Right-Angled Cable, thiab lwm yam.

Hais txog SAS
Serial Attached SCSI interface (Serial Attached SCSI, SAS) yog SCSI tiam tom ntej. Ib yam li cov tam sim no nrov Serial ATA (SATA) hard drives, SAS kuj tau txais kev siv thev naus laus zis kom ua tiav kev sib kis ceev dua thiab txhim kho qhov chaw sab hauv los ntawm kev ua kom luv cov kab txuas. SAS yog ib qho tshiab interface tsim tom qab qhov sib npaug SCSI interface. Hauv cov khoom siv niaj hnub no, kev sib txuas cables xws li MINI SAS 8087 rau 8482 CABLE, MINI SAS 8087 rau 4X SATA 7P poj niam cable, thiab lwm yam, ua lub luag haujlwm tseem ceeb. Tshwj xeeb tshaj yog txoj cai-angle kev sib txuas tswv yim ntawm MINI SAS 8087 rau 4X SATA 7P txoj cai lub kaum sab xis poj niam cable yog tshwj xeeb tshaj yog nrov nyob rau hauv cov neeg rau zaub mov ib puag ncig nrog txwv qhov chaw.

Hais txog SATA

SATA sawv cev rau Serial ATA (Serial Advanced Technology Attachment), tseem hu ua serial ATA. Nws yog lub hard drive interface specification ua ke los ntawm Intel, IBM, Dell, APT, Maxtor thiab Seagate.

Raws li feem ntau siv hard disk interface hauv kev ua lag luam tam sim no, qhov zoo tshaj plaws ntawm SATA 3.0 interface yuav tsum yog nws txoj kev loj hlob. Ob qho tib si 2.5-nti SSDs thiab HDDs siv qhov kev sib tshuam no. Nyob rau hauv cov nqe lus ntawm kev sib txuas kev daws teeb meem, MINI SAS 8087 rau 4X SATA 7P Poj Niam nrog Sideload muab cov kev daws teeb meem sab xis yooj yim, thaum MINI SAS 8087 rau 4X SATA 7P txoj cai-lub kaum sab xis poj niam cable yog tsim rau cov xwm txheej uas muaj qhov chaw txwv. Theoretical kis tau tus mob bandwidth yog 6 Gbps. Txawm hais tias nws muaj qee qhov sib txawv piv rau 10 Gbps thiab 32 Gbps bandwidth ntawm lub interface tshiab, zoo tib yam 2.5-nti SSDs tuaj yeem ua tau raws li cov kev xav tau niaj hnub ntawm cov neeg siv feem ntau, thiab kev nyeem thiab sau nrawm ntawm ib ncig ntawm 500 MB / s yog txaus.

Tus nqi ntawm cov ntaub ntawv nyob rau hauv Internet ntiaj teb no yog nce sai heev. Piv nrog rau cov interfaces tam sim no, PCI Express interface tuaj yeem muab cov ntaub ntawv xa mus sai dua thiab luv dua latency, txhim kho kev ua tau zoo thiab muaj txiaj ntsig ntawm cov koom haum. Qhov zoo yuav dhau los ua qhov tseem ceeb. Nyob rau tib lub sijhawm, cov kev daws teeb meem tshiab xws li MINI SAS 8087 rau SAS SFF-8482 Ob-hauv-One cable thiab MINI SAS 8087 rau Oculink SAS 8611 4I kuj tseem thawb ciam teb ntawm kev siv tshuab. Tshwj xeeb tshaj yog nyob rau hauv high-density cia ib puag ncig, tshwj xeeb-lub kaum sab xis connector tsim xws li MINI SAS 8087 Sab laug-angled rau 4X SATA 7P Poj Niam 90-Degree tau daws cov teeb meem thaiv.
