Kev Hloov Pauv ntawm SAS Connector Technology: Kev Hloov Pauv Cia Khoom los ntawm Parallel mus rau High-Speed ​​​​Serial

Cov txheej txheem khaws cia niaj hnub no tsis yog tsuas yog loj hlob ntawm qib terabit, muaj cov nqi hloov ntaub ntawv siab dua, tab sis kuj siv zog tsawg dua thiab siv qhov chaw tsawg dua. Cov txheej txheem no kuj xav tau kev sib txuas zoo dua los muab kev ywj pheej ntau dua. Cov neeg tsim qauv xav tau kev sib txuas me me los muab cov nqi hloov ntaub ntawv tam sim no lossis yav tom ntej. Thiab nws siv sijhawm ntau dua ib hnub rau qhov kev qhia tshwj xeeb kom yug los, txhim kho thiab maj mam loj hlob. Tshwj xeeb tshaj yog hauv kev lag luam IT, txhua yam thev naus laus zis tau txhim kho thiab hloov pauv tas li, thiab SAS (Serial Attached SCSI, Serial SCSI) kev qhia tshwj xeeb tsis yog qhov tshwj xeeb. Raws li tus neeg ua tiav rau parallel SCSI, SAS kev qhia tshwj xeeb tau nyob hauv tib neeg lub zeem muag rau qee lub sijhawm.

Tau ntau xyoo uas SAS tau nyob ib puag ncig, nws cov lus qhia tau raug txhim kho tas li. Txawm hais tias cov txheej txheem hauv qab tseem tsis tau hloov pauv ntau, cov lus qhia ntawm cov khoom sib txuas sab nraud tau hloov pauv ntau yam. Qhov no yog kev hloov kho los ntawm SAS los hloov kho rau qhov chaw ua lag luam. Piv txwv li, kev hloov pauv ntawm cov lus qhia txuas xws li MINI SAS 8087, SFF-8643, thiab SFF-8654 tau hloov pauv ntau yam kev daws teeb meem cabling thaum SAS hloov pauv los ntawm kev sib luag mus rau serial technology. Yav dhau los, parallel SCSI tuaj yeem ua haujlwm ntawm txog li 320 Mb / s dhau 16 channel hauv ib qho kev xaus lossis hom sib txawv. Tam sim no, SAS 3.0 interface, uas tseem siv dav hauv kev khaws cia hauv tuam txhab, muab bandwidth uas yog ob npaug sai dua li SAS 3 uas tsis tau hloov kho ntev, ncav cuag 24 Gbps, uas yog kwv yees li 75% ntawm bandwidth ntawm PCIe 3.0 x4 solid-state drive. Qhov tseeb MiniSAS HD connector piav qhia hauv SAS-4 specification yog me dua thiab tuaj yeem ua tiav qhov ceev dua. Qhov loj ntawm qhov Mini-SAS HD connector tshiab yog ib nrab ntawm qhov qub SCSI connector thiab 70% ntawm SAS connector. Tsis zoo li thawj SCSI parallel cable, ob qho tib si SAS thiab Mini-SAS HD muaj plaub channel. Txawm li cas los xij, nrog rau kev ceev dua, qhov ceev dua, thiab kev ywj pheej ntau dua, kuj muaj kev nce ntxiv ntawm qhov nyuaj. Vim tias qhov connector me dua, cov chaw tsim khoom cable, cov neeg sib dhos cable, thiab cov neeg tsim qauv system yuav tsum tau ua tib zoo saib xyuas cov teeb liab ntawm tag nrho cov cable sib dhos.

Txhua yam SAS cables thiab connectors, nws yooj yim heev uas yuav ua rau lawv zoo li ci ntsa iab ... Koj tau pom pes tsawg? Cov uas siv hauv kev lag luam, thiab cov uas siv rau cov khoom siv? Piv txwv li, MINI SAS 8087 rau 4X SATA 7P Txiv neej cable, SFF-8643 rau SFF-8482 cable, SlimSAS SFF-8654 8i, thiab lwm yam.

Qhov dav (sab laug, nruab nrab) ntawm Mini-SAS HD cable yog 70% ntawm qhov ntawm SAS cable (sab xis).

Tsis yog txhua lub tuam txhab tsim cable tuaj yeem muab cov teeb liab ceev ceev zoo kom ua tau raws li qhov yuav tsum tau ua ntawm cov teeb liab ntawm cov kab ke khaws cia. Cov tuam txhab tsim cable yuav tsum muab cov kev daws teeb meem zoo thiab pheej yig rau cov kab ke khaws cia tshiab. Piv txwv li, SFF-8087 rau SFF-8088 cable lossis MCIO 8i rau 2 OCuLink 4i cable. Txhawm rau tsim cov khoom siv cable ceev ceev ruaj khov thiab ruaj khov, ntau yam yuav tsum tau xav txog. Ntxiv nrog rau kev tswj hwm qhov zoo ntawm kev ua thiab cov txheej txheem ua tiav, cov neeg tsim qauv kuj yuav tsum tau them sai sai rau cov teeb liab ncaj ncees, uas yog qhov tseeb ua rau cov cables khaws cia ceev ceev niaj hnub no ua tau.
