M'malo osinthika nthawi zonse a kusungirako ndi kusamutsa deta, kufunikira kwa kulumikizana koyenera komanso kodalirika sikungatheke.Zina mwazolumikizira ndi madoko angapo omwe alipo, Mini SAS (Serial Attached SCSI), SAS (Serial Attached SCSI), ndi HD Mini SAS zimadziwika kuti ndizofunika kwambiri pama data apamwamba kwambiri.M'nkhaniyi, tikambirana za makhalidwe, ntchito, ndi ubwino wa mitundu ya madoko.
1. KumvetsetsaSAS(Serial Attached SCSI)
SAS, kapena Serial Attached SCSI, ndi njira yotumizira deta yothamanga kwambiri yomwe imagwiritsidwa ntchito makamaka polumikiza zida zosungirako monga ma hard drive, ma hard-state drive, ndi ma tepi oyendetsa kumaseva ndi malo ogwirira ntchito.Zimaphatikiza ubwino wa SCSI (Small Computer System Interface) ndi mawonekedwe a serial, kupereka kuwonjezereka, kudalirika, ndi ntchito.
Zofunikira za SAS:
- Liwiro: SAS imathandizira kusamutsa deta mpaka 12 Gb/s (SAS 3.0), ndikubwerezanso ngati SAS 4.0 kulonjeza kuthamanga kwambiri.
- Kugwirizana: SAS ndi yogwirizana kumbuyo, kulola ogwiritsa ntchito kulumikiza zida zakale za SAS ndi owongolera atsopano a SAS.
- Zomangamanga za Point-to-Point: Kulumikizana kulikonse kwa SAS kumaphatikizapo ulalo wolunjika pakati pa woyambitsa (host) ndi chandamale (chipangizo chosungira), kuonetsetsa kuti bandwidth yodzipereka.
2. Chiyambi chaMini SAS
Mini SAS, yomwe nthawi zambiri imatchedwa SFF-8087 kapena SFF-8088, ndi mawonekedwe ophatikizika a cholumikizira cha SAS chopangidwira malo opanda malo.Ngakhale kuti ndi yaying'ono, Mini SAS imasunga mphamvu zothamanga kwambiri za SAS, ndikupangitsa kuti ikhale yabwino kwa mapulogalamu omwe malo ndi ofunika kwambiri.
Mitundu ya Mini SAS Connectors:
- SFF-8087: Nthawi zambiri amagwiritsidwa ntchito mkati, cholumikizira ichi chili ndi makonzedwe a 36-pin, opereka njira zinayi za data.
- SFF-8088: Imagwiritsidwa ntchito polumikizira kunja, SFF-8088 imakhala ndi kasinthidwe ka 26-pin ndipo nthawi zambiri imagwiritsidwa ntchito posungirako zomwe zimafunikira kulumikizana kwakunja.
3. HD Mini SAS- Kukankhira Malire
HD Mini SAS, yomwe imadziwikanso kuti SFF-8644 kapena SFF-8643, ikuyimira kupita patsogolo kwaposachedwa mu kulumikizana kwa SAS.Imamanga pamaziko okhazikitsidwa ndi Mini SAS, ndikuyambitsa mawonekedwe ang'onoang'ono komanso kuthekera kochita bwino.
Zodziwika bwino za HD Mini SAS:
- Mapangidwe Okhazikika: Ndi phazi laling'ono kuposa Mini SAS, HD Mini SAS ndiyoyenera kugwiritsa ntchito pomwe kukhathamiritsa kwa malo ndikofunikira.
- Kuchulukitsa kwa Deta: HD Mini SAS imathandizira kukwera kwa data, kufika ku 24 Gb / s (SAS 3.2), ndikupangitsa kuti ikhale yabwino pantchito zogwiritsa ntchito bandwidth.
- Kusinthasintha Kowonjezereka: Mapangidwe a cholumikizira amalola kuti pakhale zosankha zosinthika, zomwe zimathandizira kukonza kasamalidwe ka chingwe.
4. Ntchito ndi Kuganizira
- Kusungirako Mabizinesi: Zolumikizira za SAS zimapeza kugwiritsidwa ntchito kwambiri munjira zosungira mabizinesi, kupereka kulumikizana kodalirika komanso kogwira ntchito kwambiri pakati pa ma seva ndi zida zosungira.
- Ma Data Center: Mini SAS ndi HD Mini SAS nthawi zambiri amagwiritsidwa ntchito m'malo opangira ma data komwe kumakhala kofunikira komanso kusamutsa deta mothamanga kwambiri.
- Zosungirako Zakunja: SFF-8088 ndi HD Mini SAS zolumikizira zimagwiritsidwa ntchito polumikiza zida zosungira zakunja, kuthandizira kusinthana kwa data mwachangu komanso kodalirika.
5. Mapeto
M'dziko lofulumira la kasamalidwe ka deta, kusankha kwa zolumikizira kumagwira ntchito yofunika kwambiri pakuzindikira bwino komanso kudalirika kwa dongosolo lonse.SAS, Mini SAS, ndi HD Mini SAS imayimira zochitika zazikulu pakusintha kwa kulumikizana kwa data, zomwe zimapereka zosankha zingapo kuti zikwaniritse zosowa zosiyanasiyana zamakompyuta amakono.Pamene ukadaulo ukupitilirabe patsogolo, zolumikizira izi zitha kukhala ndi gawo lofunikira kwambiri pakukonza tsogolo la kusungirako ndi kusamutsa deta.
