Kev Txheeb Xyuas Txog SAS Cable Los Ntawm Kev Sib Txuas Sab Hauv 8087 Mus Rau Sab Nraud High-Speed 8654
Thaum tsim lossis txhim kho cov txheej txheem khaws cia rau theem lag luam, cov chaw ua haujlwm ua haujlwm siab, lossis txawm tias qee yam khoom siv NAS, peb feem ntau ntsib ntau cov xov hlau uas zoo sib xws. Ntawm lawv, cov xov hlau cuam tshuam nrog "MINI SAS" yog qhov tseem ceeb tab sis tuaj yeem ua rau tsis meej pem. Hnub no, peb yuav nkag mus rau hauv "MINI SAS 8087 rau 8654 4i Cable" thiab "MINI SAS 8087 Cable" los pab koj nkag siab meej txog lawv cov kev siv thiab qhov sib txawv.
I. Kev Nkag Siab Yooj Yim: MINI SAS yog dab tsi?
Ua ntej, SAS (Serial Attached SCSI) yog ib qho protocol siv los txuas thiab tswj cov khoom siv sab nraud ntawm lub khoos phis tawj, feem ntau yog hard disk drives. Nws tau hloov cov thev naus laus zis parallel SCSI qub. MINI SAS yog ib daim ntawv ntawm SAS interface, uas me dua li cov SAS interfaces ua ntej thiab tuaj yeem muab kev sib txuas high-bandwidth hauv qhov chaw tsawg.
Thaum lub sijhawm hloov pauv ntawm MINI SAS, ntau yam qauv interface tau tshwm sim, ntawm cov uas SFF-8087 thiab SFF-8654 yog ob tus neeg sawv cev tseem ceeb heev.
MINI SAS 8087 (SFF-8087)Qhov no yog tus qauv qub ntawm lub qhov txuas MINI SAS sab hauv. Nws yog 36-pin interface, feem ntau siv los txuas lub motherboard (HBA card) rau lub backplane lossis ncaj qha rau ntau lub hard drive. Ib qho SFF-8087 interface sib sau ua plaub SAS channels, txhua tus muaj bandwidth theoretical ntawm 6Gbps (nyob ntawm SAS version, nws kuj tuaj yeem yog 3Gbps lossis 12Gbps), yog li tag nrho bandwidth tuaj yeem ncav cuag txog 24Gbps.
MINI SAS 8654 (SFF-8654)Qhov no yog tus qauv txuas sab nraud tshiab dua, feem ntau hu ua Mini SAS HD. Nws kuj muaj 36 tus pin tab sis nws lub cev me dua thiab compact dua hauv kev tsim. Nws feem ntau yog siv los txuas cov chaw nres nkoj sab nraud ntawm cov khoom siv, xws li los ntawm tus tswv tsev server mus rau lub txee disk sab nraud. Ib qho SFF-8654 interface kuj txhawb nqa plaub SAS channel thiab sib xws nrog SAS 3.0 (12Gbps) thiab cov qauv siab dua.
II. Kev Tshawb Fawb Tseem Ceeb: MINI SAS 8087 rau 8654 4i Cable
Tam sim no, cia peb tsom mus rau lo lus tseem ceeb thawj zaug:MINI SAS 8087 rau 8654 4i Cable.
Los ntawm lub npe, peb tuaj yeem txhais ncaj qha:
Ib kawg yog SFF-8087 interface (sab hauv interface)
Qhov kawg yog SFF-8654 interface (sab nraud interface)
"4i" feem ntau sawv cev rau "4 channel sab hauv", ntawm no nws tuaj yeem nkag siab tias cov cable no nqa tag nrho 4-channel SAS kev sib txuas.
Lub luag haujlwm tseem ceeb ntawm lub cable no yog dab tsi? - Nws yog "choj" txuas lub chaw cia khoom sab hauv thiab sab nraud ntawm lub server.
Cov xwm txheej ntawm daim ntawv thov:
Xav txog koj muaj lub server lossis chaw ua haujlwm nrog daim npav HBA ntawm lub motherboard nrog lub interface SFF-8087. Tam sim no, koj yuav tsum txuas lub txee SAS disk array sab nraud, thiab lub interface sab nraud ntawm lub txee disk array no yog SFF-8654.
Lub sijhawm no, lubMINI SAS 8087 rau 8654 4i Cablelos ua si. Koj ntxig qhov kawg SFF-8087 rau hauv daim npav HBA sab hauv ntawm lub server, thiab txuas qhov kawg SFF-8654 rau qhov chaw nres nkoj ntawm lub txee disk sab nraud. Ua li no, lub server tuaj yeem paub thiab tswj hwm txhua lub hard drive hauv lub txee disk.
Hauv cov lus yooj yim, qhov no yog kab txuas "los ntawm sab hauv mus rau sab nraud", ua tiav kev xa cov ntaub ntawv sai thiab ceev los ntawm SAS maub los hauv lub server mus rau lub cuab yeej cia sab nraud.
III. Kev Nkag Siab Sib Piv:MINI SAS 8087 Cable
Lo lus thib ob "MINI SAS 8087 Cable" yog lub tswv yim dav dua, hais txog lub cable nrog ib lossis ob qho kawg yog SFF-8087 interfaces. Nws feem ntau yog siv rau kev sib txuas sab hauv ntawm cov khoom siv.
Cov hom MINI SAS 8087 Cable feem ntau muaj xws li:
Hom kev sib txuas ncaj qha (SFF-8087 rau SFF-8087): Hom feem ntau, siv rau kev sib txuas ncaj qha ntawm daim npav HBA thiab lub backplane server.
Hom ceg (SFF-8087 rau 4x SATA/SAS): Ib kawg yog SFF-8087, thiab lwm qhov kawg ceg tawm mus rau hauv 4 qhov sib txuas ntawm SATA lossis SAS. Cov xov hlau no feem ntau siv los txuas daim npav HBA ncaj qha rau 4 lub hard drive SATA lossis SAS yam tsis tas yuav hla lub backplane.
Hom ceg rov qab (SFF-8087 rau SFF-8643): Siv los txuas cov npav HBA qub nrog cov interfaces hloov tshiab (xws li SFF-8643) rau lub backplane lossis hard drives.
Qhov sib txawv tseem ceeb ntawm 8087 txog 8654 cable:
Daim ntawv thov teb: MINI SAS 8087 Cable feem ntau yog siv rau hauv lub chassis server; thaum 8087 txog 8654 Cable yog siv tshwj xeeb los txuas cov khoom siv sab hauv thiab sab nraud.
Kev teeb tsa ua haujlwm: Tus thawj yog "kev sib txuas sab hauv", thaum tus tom kawg yog "choj sab hauv-sab nraud".
