Indlela yokukhetha i-Ikhebula le-SATA le-SFF-8087？
Esikhathini samanje sokuqhuma kwedatha, kungakhathaliseki ukuthi kwakhiwe i-NAS esebenza kahle kakhulu (i-Network Attached Storage) noma ukusetha indawo yokusebenza, ukunwetshwa kwesitoreji sangaphakathi kubhekene nezinselele ezinkulu zesikhala. Kwabathandi abathanda amaseva e-DIY noma ukuthuthukisa izinhlelo zabo zokugcina, i-engeli yokugoba yezintambo ivame ukunquma ukuthi ukuhamba komoya ngaphakathi kwekesi kubushelelezi yini nokuthi isembozo singavalwa yini. Lesi sihloko sizogxila engxenyeni ebalulekile,I-Mini SAS HD SFF-8087 I-engeli Engakwesokudla kuya ku-4 SATA 7P I-engeli Engakwesokudla, bese nixoxa ngezindlela ezivamile ezifana naleziikhebula le-sata elingakwesokudla elingu-8087 eliya ekhoneni lesokudlafuthiikhebula le-sata elingakwesokunxele sff 8087 eliya kwesokudla, okwembula indlela ukukhetha ikhebula okufanele okungathuthukisa ngayo ukwakheka kwehadiwe yakho.
I. Kungani Ukhetha "I-Engela Efanele"?
Ezixazululweni zokuxhumanisa isitoreji zendabuko, izintambo eziqondile zilungele ukuxhuma nokukhipha izintambo, kodwa zivame ukubangela ukuminyana okukhulu kwezintambo ezimweni ezincane. Uma sethula izintambo,Ikhebula le-Mini SAS HD SFF-8087 eliyi-engeli yangakwesokudla kuya ku-4 SATA 7P eliyi-engeli yangakwesokudlaUma ufaka ikesi, inzuzo esobala kakhulu ukonga isikhala. Ukuphela kwale khebula yi-SFF-8087 right-engela, evame ukuxhunywa ekhadini le-RAID noma ekhadini le-HBA; okunye ukuphela kuyi-interfaces ezine ze-SATA 7P ezine-engela yesokudla, ezixhunywa kuma-hard drive noma ama-backplanes. Lo mklamo "we-double right-engela" uvumela ikhebula ukuthi lihambe phezu kwebhodi lomama noma ikhadi lokunweba, okunciphisa kakhulu isidingo sokuphakama kwekhebula kuleli khesi.
Isibonelo, uma sifuna umkhiqizo othize ocacisiwe, sivame ukufaka amagama angukhiyenjengekhebula le-andle 8087 elingakwesokudla eliya ekhoneni lesokudla le-sataLokhu ngokuvamile kusho ukuthi umsebenzisi ufuna ukuthi zombili iziphetho zibe yimiklamo ye-engeli yesokudla ukuze kuhlangatshezwane nezidingo zokufaka kuzo zombili izinhlangothi. Kubalulekile ukuqaphela ukuthi nakuba elithi "right andle" lingeyona indlela ejwayelekile yokupela, livame kakhulu ekusesheni kwangempela. Likhomba ngokunembile isimo lapho kudingeka khona ukugoba okungu-90-degree ekhoneni, okuqinisekisa ukuthi isikhombimsebenzisi ekhadini le-HBA asonakali ngokudonsa ikhebula.
II. Ukukhetha Phakathi Kwesobunxele Nesokudla: Ukuqonda Ukuqondiswa
Akuzona zonke izakhiwo zangaphakathi zamakesi ekhompyutha ezifanayo. Ngezinye izikhathi, isikhombikubona sekhadi lakho le-RAID sibhekene nephaneli eseceleni yekesi, kuyilapho izikhala ze-hard drive zikolunye uhlangothi. Ezimweni ezinjalo, okuvamileIkhebula le-Mini SAS HD SFF-8087 eliyi-engeli yangakwesokudla kuya ku-4 SATA 7P eliyi-engeli yangakwesokudlakungase kungahambelani kahle nendlela yokuxhuma izintambo, njengoba ungase udinge isikhombimsebenzisi se-SFF-8087 "esibheke kwesobunxele". Yilapho-keikhebula le-sata elingakwesokunxele sff 8087 eliya kwesokudlaIngena. Ichaza ikhebula elinesixhumi se-SFF-8087 esinohlangothi lwesobunxele (lapho ikhebula liphuma khona ohlangothini lwesobunxele lwesixhumi esibonakalayo) kolunye uhlangothi kanye nesixhumi se-SATA esinohlangothi lwesokudla kolunye. Le nhlanganisela enembile yama-engeli angakwesokunxele nangakwesokudla ikuvumela ukuthi uxhume kalula ama-hard drive atholakala ezinhlangothini ezahlukene kumaseva e-rack angu-1U noma angu-2U ngaphandle kokugoba ikhebula ngokweqile. Ngokuphambene nalokho, i-ikhebula le-sata elingakwesokudla elingu-8087 eliya ekhoneni lesokudla, okungenzeka ukuthi zombili iziphetho zibekwe ngakwesokudla, kunomehluko omncane ezimweni zokusetshenziswa. Ukungayinaki le mehluko wesobunxele kwesokudla nokuphoqelela ukufakwa kungabangela ukuthi ikhebula lisonteke, okwandisa ingozi yokuncipha kwesignali.
III. Amapharamitha Obuchwepheshe kanye Nokuhlaziywa Kokuhambisana
Uma ukhethaIkhebula le-Mini SAS HD SFF-8087 eliyi-engeli yangakwesokudla kuya ku-4 SATA 7P eliyi-engeli yangakwesokudla, kubalulekile ukucabangela hhayi ama-engeli esibonakalayo kuphela kodwa nokusekelwa kwephrothokholi. Njengamanje, izintambo eziyinhloko zalolu hlobo zisekela amazinga okudlulisa e-SAS 6Gbps noma i-SAS 12Gbps (Serial Attached SCSI) futhi zihambisana ne-SATA 3.0 standard. Uma usebenzisa i-ikhebula le-sata elingakwesokudla elingu-8087 eliya ekhoneni lesokudlaukuxhuma ama-hard drive ajwayelekile e-SATA noma ama-solid-state drive ajwayelekile, ikhebula ngokwalo akunakwenzeka ukuthi libe yisithiyo sokusebenza, uma nje isivikelo sangaphakathi kanye ne-wire gauge (AWG, American Wire Gauge) yekhebula kusezingeni eliphezulu.
Kuyafaneleka ukuqaphela ukuthi nakubaikhebula le-sata elingakwesokunxele sff 8087 eliya kwesokudlaIsebenza ngendlela efanayo nekhebula elijwayelekile eliyi-engeli yesokudla, ukwakheka kwesikhunta kanye nocingo okuyinkimbinkimbi kuvame ukuholela ezindleleni zokukhiqiza eziphakeme. Lapho bethenga, abasebenzisi kufanele bakhethe imikhiqizo ekhombisa ngokucacile incazelo ye-pinout kanye namazinga okudlulisa asekelwayo ukuze bagweme ukulimaza ikhwalithi nokubangela ukudluliswa kwedatha okungazinzile.
IV. Izimo Zokufaka Ezisebenzayo kanye Nokuhlangenwe Nakho Komsebenzisi
Ezinqubweni zokufaka zangempela, abasebenzisi abasebenziseIkhebula le-Mini SAS HD SFF-8087 eliyi-engeli yangakwesokudla kuya ku-4 SATA 7P eliyi-engeli yangakwesokudlabavame ukudumisa ukuhleleka kwekhava yangaphakathi. Isibonelo, uma ifakiwe kukhava elincane le-Micro-ATX, ikhadi le-RAID livame ukuba eduze kwendawo yokunikezwa kwamandla. Besebenzisa ikhebula elijwayelekile le-SFF-8087 eliqondile, ikhebula lingashaya ngqo ukunikezwa kwamandla noma iphaneli eseceleni, okubangela ukuthi iphaneli eseceleni iqhume. Kodwa-ke, ngokusebenzisa i-ikhebula le-sata elingakwesokudla elingu-8087 eliya ekhoneni lesokudla, ikhebula liphenduka ama-degree angu-90 ngqo kusuka ku-interface futhi linwebeka ngokuhambisana nebhodi lebhodi, ligwema ngokuphelele izithiyo. Ngaphezu kwalokho, ekwakhiweni kwezintambo ze-backplane, uma ikheji le-hard disk litholakala phansi ngaphambili kwe-chassis futhi ikhadi le-HBA liphakathi nendawo ye-PCIe, i-engeli yesobunxeleIkhebula le-SATA le-SFF 8087 eliya ekhoneni lesokudlakungenza indlela yokuxhuma izintambo ibe nengqondo kakhulu ngokomzimba. Ngokulungisa indlela yokugoba yesiphelo se-SATA, izintambo ezine ze-SATA zingafakwa kahle kudiski eqinile, kugwenywe isimo esibi sokuhlakazeka njenge-"octopus".
V. Market乱象 kanye neziphakamiso zokuthenga
Njengoba lezi zesekeli zikhiqizwa kakhulu ngabantu besithathu, izindlela zazo zokuqamba amagama ziyahlukahluka kakhulu. Abanye abathengisi bangase babhekisele ku-"I-Mini SAS HD SFF-8087 I-engeli Engakwesokudla kuya ku-4 SATA 7P I-engeli Engakwesokudla"njengo-"Dlulisela phambili ku-8087 kuya ku-90 Degree SATA", ngenkathi ushayela ucingo "Ikhebula le-SATA le-SFF 8087 elingakwesokunxele ukuya kwelesokudla"njengo-"Reverse 8087 to 90 Degree SATA". Ngakho-ke, uma usesha, kunconywa ukusebenzisa amagama angukhiye anjengelithi "reverse" noma "left angle" ngokuhlanganiswa, bese ubhekisela ezithombeni ezibonakalayo zezintambo ukuze uthole ukuthi iziphi izindawo zokuxhuma izintambo.
Ekugcineni, kungakhathaliseki ukuthi ukuthola "ikhebula le-sata elingakwesokudla elingu-8087 eliya ekhoneni lesokudla"ukwakha uhlu lwediski, noma ukudinga okukhethekile"ikhebula le-sata elingakwesokunxele sff 8087 eliya kwesokudla"ukulungisa iseva endala, sicela uqinisekise ukuthi uqinisekisa usayizi obonakalayo wesixhumi esibonakalayo. Nakuba i-SFF-8087 ingenye yezindinganiso zokuqala zezixhumi ezisebenzisanayo ze-Mini SAS HD, indlela yayo yokukhiya ihlukile kune-SFF-8643 ebuyekeziwe. Qinisekisa ukuthi isixhumi esisebenzisanayo sebhodi lakho noma isilawuli siyahambisana nayo, ukuzeI-Mini SAS HD SFF-8087 I-engeli Engakwesokudla kuya ku-4 SATA 7P I-engeli Engakwesokudlaingenza umsebenzi wayo ohlosiwe.
Ekuphetheni, ukukhetha i-engeli encane yekhebula kubonisa ukuphishekela okukhulu kwe-DIYer imininingwane. Ngokuqonda okujulile kwemikhiqizo emelelwe amagama angukhiye amathathu angenhla, ungenza ngokwezifiso ngokuphelele isiteshi sedatha esiphelele ngokwesakhiwo sekesi lakho.
