Nyob rau hauv ib puas-evolving toj roob hauv pes ntawm cov ntaub ntawv cia thiab hloov lwm lub tsev, qhov tseem ceeb ntawm npaum thiab txhim khu kev qha connectivity yuav tsis overstated.Ntawm ntau qhov sib txuas thiab cov chaw nres nkoj muaj, Mini SAS (Serial Attached SCSI), SAS (Serial Attached SCSI), thiab HD Mini SAS sawv tawm raws li cov khoom tseem ceeb hauv cov ntaub ntawv ua haujlwm siab.Hauv tsab xov xwm no, peb yuav piav qhia txog cov yam ntxwv, kev siv, thiab qhov zoo ntawm cov chaw nres nkoj no.
1. Kev nkag siabSAS(Serial Attached SCSI)
SAS, los yog Serial Attached SCSI, yog ib tug high-ceev cov ntaub ntawv hloov lwm lub tsev raws tu qauv siv feem ntau rau kev sib txuas cov cuab yeej cia xws li hard drives, solid-state drives, thiab daim kab xev drives rau servers thiab workstations.Nws muab cov txiaj ntsig zoo ntawm SCSI (Me Me Computer System Interface) nrog rau qhov sib txuas sib txuas, muab kev ua kom muaj zog ntxiv, kev ntseeg siab, thiab kev ua haujlwm.
Cov yam ntxwv tseem ceeb ntawm SAS:
- Ceev: SAS txhawb nqa cov ntaub ntawv hloov pauv mus txog 12 Gb / s (SAS 3.0), nrog rau kev rov ua dua tom qab zoo li SAS 4.0 cog lus txawm tias qhov nrawm dua.
- Kev sib raug zoo: SAS yog rov qab sib xws, tso cai rau cov neeg siv txuas cov khoom qub SAS nrog cov tswj hwm SAS tshiab.
- Point-to-Point Architecture: Txhua qhov kev sib txuas SAS feem ntau muaj qhov sib txuas ntawm qhov taw tes rau ntawm qhov pib (tus tswv tsev) thiab lub hom phiaj (cov cuab yeej khaws cia), kom ntseeg tau tias muaj kev sib koom siab bandwidth.
2. Taw qhia rauMini SAS
Mini SAS, feem ntau hu ua SFF-8087 los yog SFF-8088, yog ib daim ntawv cog lus ntawm SAS connector tsim los rau qhov chaw tsis muaj kev txwv.Txawm hais tias nws qhov me me, Mini SAS tswj hwm lub peev xwm ceev ntawm SAS, ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov ntawv thov uas qhov chaw yog tus nqi them.
Hom Mini SAS Connectors:
- SFF-8087: Feem ntau siv sab hauv, cov khoom sib txuas no muaj 36-pin teeb tsa, muab plaub txoj kab ntawm cov ntaub ntawv.
- SFF-8088: Siv rau kev sib txuas sab nraud, SFF-8088 nta 26-pin configuration thiab feem ntau ua haujlwm hauv cov kev daws teeb meem uas xav tau kev sib txuas sab nraud.
3. HD Mini SAS- Pushing qhov txwv
HD Mini SAS, tseem hu ua SFF-8644 lossis SFF-8643, sawv cev rau kev nce qib tshiab hauv SAS txuas.Nws ua raws li lub hauv paus uas tau tso los ntawm Mini SAS, qhia txog daim ntawv me me thiab txhim kho kev ua tau zoo.
Cov yam ntxwv tseem ceeb ntawm HD Mini SAS:
- Compact Design: Nrog tus hneev taw me dua li Mini SAS, HD Mini SAS yog qhov zoo rau cov ntawv thov uas qhov chaw optimization tseem ceeb heev.
- Cov ntaub ntawv nce ntxiv: HD Mini SAS txhawb nqa cov ntaub ntawv hloov pauv ntau dua, nce mus txog 24 Gb / s (SAS 3.2), ua rau nws zoo tagnrho rau kev ua haujlwm siab bandwidth.
- Txhim kho Flexibility: Cov qauv tsim txuas tso cai rau ntau txoj kev xaiv cabling yooj yim, pab txhawb kev txhim kho cable tswj.
4. Daim ntawv thov thiab kev txiav txim siab
- Enterprise Cia: SAS connectors pom dav siv nyob rau hauv lub lag luam kev daws teeb meem, muab ib tug txhim khu kev qha thiab ua tau zoo kev twb kev txuas ntawm servers thiab cia li.
- Cov Chaw Cov Ntaub Ntawv: Mini SAS thiab HD Mini SAS nquag ua haujlwm nyob rau hauv cov ntaub ntawv chaw ib puag ncig uas muaj peev xwm cabling thiab cov ntaub ntawv ceev ceev yog qhov tseem ceeb.
- Sab Nraud Cia Arrays: SFF-8088 thiab HD Mini SAS connectors feem ntau yog siv rau kev sib txuas rau sab nraud cia arrays, pab kom ceev thiab txhim khu kev qha cov ntaub ntawv pauv.
5. Cov lus xaus
Nyob rau hauv lub ntiaj teb ceev-paced ntawm kev tswj cov ntaub ntawv, kev xaiv ntawm connectors plays lub luag hauj lwm tseem ceeb hauv kev txiav txim siab efficiency thiab kev cia siab ntawm tag nrho cov system.SAS, Mini SAS, thiab HD Mini SAS sawv cev rau qhov tseem ceeb hauv kev hloov pauv ntawm cov ntaub ntawv sib txuas, muab ntau txoj hauv kev los ua kom tau raws li cov kev xav tau sib txawv ntawm cov khoom siv niaj hnub no.Raws li kev siv thev naus laus zis txuas ntxiv mus, cov khoom sib txuas no yuav zoo li ua lub luag haujlwm tseem ceeb hauv kev txhim kho yav tom ntej ntawm cov ntaub ntawv khaws cia thiab hloov pauv.
