SAS Cable Txheej txheem cej luam Ntawm Internal Interconnection 8087 rau Sab Nraud High-Speed 8654
Thaum txhim kho lossis txhim kho kev lag luam-theem chaw cia khoom, chaw ua haujlwm ua haujlwm siab, lossis txawm tias qee yam NAS cov khoom siv, peb feem ntau ntsib ntau cov cables uas zoo sib xws. Ntawm lawv, cables ntsig txog "MINI SAS" yog qhov tseem ceeb tab sis tuaj yeem ua rau tsis meej pem. Hnub no, peb yuav delve rau hauv "MINI SAS 8087 rau 8654 4i Cable"thiab"MINI SAS 8087 Cable"los pab koj kom 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 cov txheej txheem siv los txuas thiab tswj cov khoom siv sab nraud ntawm lub khoos phis tawj, feem ntau hard disk drives. Nws tau hloov cov thev naus laus zis niaj hnub sib luag SCSI. MINI SAS yog ib daim ntawv ntawm lub cev ntawm SAS interface, uas yog me dua li SAS interfaces ua ntej thiab tuaj yeem muab kev sib txuas siab bandwidth hauv qhov chaw tsawg.
Thaum lub sij hawm evolution ntawm MINI SAS, ntau yam interface qauv tau tshwm sim, cov uas SFF-8087 thiab SFF-8654 yog ob tug neeg sawv cev tseem ceeb heev.
MINI SAS 8087 (SFF-8087) NPE: Qhov no yog tus qauv classic ntawm sab hauv MINI SAS connector. Nws yog 36-pin interface, feem ntau yog siv los txuas lub motherboard (HBA card) rau lub nraub qaum lossis ncaj qha rau ntau lub hard drive. Ib qho SFF-8087 interface sib sau plaub SAS raws, txhua qhov muaj qhov theoretical bandwidth ntawm 6Gbps (nyob ntawm SAS version, nws tuaj yeem yog 3Gbps lossis 12Gbps), yog li tag nrho cov bandwidth tuaj yeem ncav cuag 24Gbps.
MINI SAS 8654 (SFF-8654) NPE: Qhov no yog tus qauv txuas sab nraud tshiab, feem ntau hu ua Mini SAS HD. Nws kuj muaj 36 tus pins tab sis lub cev me dua thiab ntau dua hauv kev tsim. Nws yog tsuas yog siv los txuas cov chaw nres nkoj sab nraud ntawm cov khoom siv, xws li los ntawm lub server host mus rau sab nraud disk txee. Ib qho SFF-8654 interface kuj txhawb nqa plaub SAS raws thiab sib xws nrog SAS 3.0 (12Gbps) thiab ntau dua.
II. Core Analysis: MINI SAS 8087 rau 8654 4i Cable
Tam sim no, cia peb tsom mus rau thawj lo lus tseem ceeb:MINI SAS 8087 rau 8654 4i Cable.
Los ntawm lub npe, peb tuaj yeem txhais ncaj qha:
Ib kawg yog SFF-8087 interface (internal interface)
Lwm qhov kawg yog SFF-8654 interface (sab nraud interface)
"4i" feem ntau yog sawv cev rau "4 channels sab hauv", ntawm no nws tuaj yeem nkag siab tias cov cable no ua tiav 4-channel SAS txuas.
Lub luag haujlwm tseem ceeb ntawm cov kab no yog dab tsi? - Nws yog "choj" txuas rau sab hauv thiab sab nraud nthuav dav ntawm cov neeg rau zaub mov.
Tej yam kev thov scenarios:
Xav txog tias koj muaj ntauwd server lossis chaw ua haujlwm nrog daim npav HBA ntawm lub motherboard nrog SFF-8087 interface. Tam sim no, koj yuav tsum tau txuas rau sab nraud SAS disk array txee, thiab sab nraud interface ntawm no disk array txee yog raws nraim SFF-8654.
Lub sijhawm no, lubMINI SAS 8087 rau 8654 4i Cablelos ua si. Koj ntxig rau SFF-8087 kawg rau hauv daim npav HBA sab hauv ntawm cov neeg rau zaub mov, thiab txuas SFF-8654 kawg rau qhov chaw nres nkoj ntawm lub txee sab nraud. Ua li no, tus neeg rau zaub mov tuaj yeem paub thiab tswj tag nrho cov hard drives hauv lub txee disk.
Hauv cov ntsiab lus yooj yim, qhov no yog "los ntawm sab hauv mus rau sab nraud" kev sib txuas kab, ua tiav cov ntaub ntawv tsis sib haum xeeb thiab kev kub ceev kis tau los ntawm SAS maub los hauv lub server mus rau sab nraud cia khoom.
III. Kev nkag siab sib piv:MINI SAS 8087 Cable
Qhov thib ob lo lus tseem ceeb "MINI SAS 8087 Cable" yog lub tswvyim dav dua, xa mus rau 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.
Ntau hom MINI SAS 8087 Cable suav nrog:
Hom kev sib txuas ncaj qha (SFF-8087 rau SFF-8087): Hom ntau tshaj plaws, siv rau kev sib txuas ncaj qha ntawm HBA daim npav thiab server backplane.
Ceg hom (SFF-8087 rau 4x SATA / SAS): Ib kawg yog SFF-8087, thiab lwm qhov kawg ceg tawm mus rau 4 ywj siab SATA lossis SAS cov ntaub ntawv cuam tshuam. Cov kab no feem ntau siv los txuas ncaj qha rau daim npav HBA rau 4 ywj siab SATA lossis SAS hard drives yam tsis tau hla lub dav hlau rov qab.
Rov qab ceg hom (SFF-8087 rau SFF-8643): Siv los txuas cov ntawv qub HBA nrog cov kev hloov kho tshiab (xws li SFF-8643) rau lub nraub qaum lossis lub zog tsav.
Qhov sib txawv tseem ceeb ntawm 8087 txog 8654 cable:
Daim ntawv thov teb: MINI SAS 8087 Cable yog siv nyob rau hauv lub server chassis; thaum 8087 rau 8654 Cable tshwj xeeb yog siv los txuas cov khoom siv sab hauv thiab sab nraud.
Kev ua haujlwm ua haujlwm: Lub qub yog "internal interconnection" cable, thaum lub tom kawg yog "sab hauv-sab nrauv choj" cable.
