I-MINI SAS HD SFF-8087 ukuya kwi-4X SATA eLungileyo eLungileyo lweSpeed ​​esiPhezulu soQhagamshelwano lweSiva

Ziziphi iimpawu zeentambo ze-SAS kunye neentambo ze-SAS

Intambo ye-SAS yintsimi yokugcina i-disk media sesona sixhobo sibaluleke kakhulu, yonke idatha kunye nolwazi kufuneka lugcinwe kwi-disk media. Isantya sokufunda sedatha sichongwa lunxibelelwano lonxibelelwano lwemidiya yediski. Ngaphambili, besihlala sigcina idatha yethu ngokusebenzisa i-SCSI okanye i-SATA ujongano kunye nee-hard drives. Kungenxa yophuhliso olukhawulezayo lweteknoloji ye-SATA kunye neenzuzo ezahlukeneyo abantu abaninzi baya kuqwalasela ukuba kukho indlela yokudibanisa zombini i-SATA kunye ne-SCSI, ukwenzela ukuba izibonelelo zombini zidlalwe ngexesha elinye. Kule meko, i-SAS iye yavela. Izixhobo zogcino lwenethiwekhi zinokwahlulwa ngokurhabaxa zibe ziindidi ezintathu eziphambili, ezizezi, isiphelo esiphakathi esiphakamileyo kunye nesiphelo esikufuphi (Near-Line). Izixhobo zokugcina eziphezulu zizininzi zeFiber channel. Ngenxa yesantya sokuhanjiswa ngokukhawuleza kweshaneli yeFiber, uninzi lwezixhobo eziphezulu zokugcina izixhobo zefiber optical zisetyenziswa kumthamo omkhulu wexesha lokugcinwa kwedatha engundoqo yenqanaba lomsebenzi. Isixhobo sokugcina esiphakathi sisixhobo se-SCSI, kwaye sinembali ende, isetyenziselwa ukugcinwa kobuninzi bedatha ebalulekileyo yezinga lezorhwebo. Ifinyeziwe njenge (SATA), isetyenziselwa ukugcinwa kobuninzi beedatha ezingabalulekanga kwaye ijoliswe ekutshintsheni i-backup data yangaphambili usebenzisa i-tape. Inzuzo engcono kakhulu yeFiber Channel yokugcina izixhobo kukuhanjiswa ngokukhawuleza, kodwa inexabiso eliphezulu kwaye kunzima ukuyigcina; Izixhobo ze-SCSI zinokufikelela ngokukhawuleza kunye nexabiso eliphakathi, kodwa lincinci kancinci, ikhadi ngalinye le-SCSI lidibanisa ukuya kuthi ga kwi-15 (itshaneli enye) okanye izixhobo ezingama-30 (ezimbini). I-SATA bubuchwephesha obukhula ngokukhawuleza kwiminyaka yakutshanje. Olona ncedo lwayo lukhulu kukuba lutshiphu, kwaye isantya asicotha kakhulu kunojongano lweSCSI. Ngophuhliso lwetekhnoloji, isantya sokufundwa kwedatha ye-SATA siyasondela kwaye sigqithise i-interface ye-SCSI. Ukongeza, njengoko i-hard disk ye-SATA isiya ingabizi kwaye ibiza kakhulu, inokusetyenziselwa ukugcinwa kwedatha ngokuthe ngcembe. Ke ukugcinwa kweshishini lemveli kuba kuqwalaselwe ukusebenza kunye nokuzinza, kunye ne-SCSI hard disk kunye ne-fiber optic channel njengeqonga lokugcina, i-SATA isetyenziswa kakhulu kwidatha engabalulekanga okanye ikhompyuter yekhompyuter, kodwa ngokunyuka kobuchwepheshe beSATA kunye nezixhobo zeSATA. abaqolileyo, le mo iyatshintshwa, abantu abaninzi baqala ukunikela ingqalelo kwi-SATA le ndlela yoqhagamshelo logcino lwedatha.
