Uhlolojikelele lwekhebula le-SAS Kusukela ku-Internal Interconnection 8087 ukuya ku-High-Speed 8654 yangaphandle
Lapho sakha noma sithuthukisa amasistimu okugcina ezinga lebhizinisi, izindawo zokusebenza ezisebenza kahle kakhulu, noma ngisho namadivayisi athile e-NAS, sivame ukuhlangana namakhebuli ahlukahlukene abukeka afana. Phakathi kwazo, amakhebuli ahlobene ne-"MINI SAS" abalulekile kodwa angadida. Namuhla sizohlola "I-MINI SAS 8087 kuya ku-8654 4i Ikhebula"futhi"Ikhebula le-MINI SAS 8087"ukukusiza ukuthi uqonde ngokucacile ukusetshenziswa nokuhlukana kwazo.
I. Ukuqonda Okuyisisekelo: Iyini i-MINI SAS?
Okokuqala, i-SAS (Serial Attached SCSI) iyiphrothokholi esetshenziselwa ukuxhuma nokulawula amadivaysi angaphandle ekhompyutha, ikakhulukazi ama-hard disk drive. Ithathe indawo yobuchwepheshe be-SCSI obuhambisana nesikhathi. I-MINI SAS iwuhlobo oluphathekayo lwe-interface ye-SAS, encane kune-interface ye-SAS yangaphambili futhi ingahlinzeka ngoxhumano lwe-bandwidth ephezulu ezindaweni ezilinganiselwe.
Ngesikhathi sokuvela kwe-MINI SAS, kuye kwavela amamodeli e-interface ahlukahlukene, phakathi kwawo i-SFF-8087 ne-SFF-8654 abangabameleli ababili ababaluleke kakhulu.
I-MINI SAS 8087 (SFF-8087): Lena imodeli yakudala yesixhumi sangaphakathi se-MINI SAS. Kuyisixhumi esibonakalayo esinamaphini angu-36, ngokuvamile asetshenziselwa ukuxhuma ibhodi lomama (ikhadi le-HBA) kubhanoyi engemuva noma ngokuqondile kuma-hard drive amaningi. Isixhumi esibonakalayo esisodwa se-SFF-8087 sihlanganisa iziteshi ezine ze-SAS, ngasinye sinomkhawulokudonsa wethiyori we-6Gbps (kuye ngenguqulo ye-SAS, kungase futhi kube yi-3Gbps noma i-12Gbps), ngaleyo ndlela isamba somkhawulokudonsa singafinyelela ku-24Gbps.
I-MINI SAS 8654 (SFF-8654): Leli izinga elisha lesixhumi sangaphandle, elivame ukubizwa ngokuthi i-Mini SAS HD. Futhi inamaphini angu-36 kodwa incane ngokomzimba futhi ihlangene kakhulu ekwakhiweni. Isetshenziswa kakhulu ukuxhuma izimbobo zangaphandle zamadivayisi, njengokusuka kumsingathi weseva kuya kukhabhinethi yediski yangaphandle. Isixhumi esibonakalayo esisodwa se-SFF-8654 siphinde sisekele iziteshi ezine ze-SAS futhi sihambisana ne-SAS 3.0 (12Gbps) nezinguqulo eziphakeme.
II. Ukuhlaziywa Okubalulekile: I-MINI SAS 8087 kuya ku-8654 4i Ikhebula
Manje, ake sigxile egameni elingukhiye lokuqala:I-MINI SAS 8087 kuya ku-8654 4i Ikhebula.
Kusukela egameni, singatolika ngokuqondile:
Isiphetho esisodwa isixhumi esibonakalayo se-SFF-8087 (i-interface yangaphakathi)
Esinye isiphetho yi-SFF-8654 interface (i-interface yangaphandle)
"I-4i" ivamise ukumela "iziteshi ezi-4 ngaphakathi", lapha ingaqondwa njengoba le ntambo ithwala uxhumano oluphelele lwe-SAS lweziteshi ezi-4.
Uyini umsebenzi oyinhloko wale khebula? - "Yibhuloho" elixhuma isitoreji sokunweba sangaphakathi nangaphandle seseva.
Izimo zohlelo lokusebenza ezijwayelekile:
Cabanga ukuthi uneseva yombhoshongo noma indawo yokusebenza enekhadi le-HBA ebhodini lomama elinesixhumi esibonakalayo se-SFF-8087. Manje, udinga ukuxhuma iKhabhinethi yangaphandle ye-disk ye-SAS yangaphandle, futhi isikhombimsebenzisi sangaphandle salolu hlelo lwe-disk cabinet luyi-SFF-8654 ncamashi.
Ngalesi sikhathi, i-I-MINI SAS 8087 kuya ku-8654 4i Ikhebulauyadlala. Ufaka isiphetho se-SFF-8087 ekhadini le-HBA langaphakathi leseva, bese uxhuma isiphetho se-SFF-8654 embobeni yekhabhinethi yediski yangaphandle. Ngale ndlela, iseva ingakwazi ukubona futhi ilawule wonke ama-hard drive kukhabhinethi yediski.
Ngamagama alula, lona ulayini woxhumano "osuka ngaphakathi kuye ngaphandle", ofinyelela ukudluliswa kwedatha okungenamthungo nesivinini esikhulu kusuka kusilawuli se-SAS esingaphakathi kweseva kuya kudivayisi yokugcina yangaphandle.
III. Ukuqonda okuqhathanisayo:Ikhebula le-MINI SAS 8087
Igama elingukhiye lesibili elithi "MINI SAS 8087 Cable" liwumqondo obanzi, libhekisa kukhebula enomkhawulo owodwa noma yomibili iyi-SFF-8087. Ngokuvamile isetshenziselwa ukuxhumana kwangaphakathi kwamadivayisi.
Izinhlobo ezijwayelekile ze-MINI SAS 8087 Cable zifaka:
Uhlobo lokuxhuma oluqondile (SFF-8087 kuya ku-SFF-8087): Uhlobo oluvame kakhulu, olusetshenziselwa ukuxhumana okuqondile phakathi kwekhadi le-HBA nendiza yangemuva yeseva.
Uhlobo lwegatsha (SFF-8087 kuya ku-4x SATA/SAS): Isiphetho esisodwa yi-SFF-8087, kanti esinye isiphetho siphuma kusixhumi esibonakalayo sedatha ye-SATA engu-4 noma ye-SAS. Le ntambo ivamise ukusetshenziselwa ukuxhuma ngqo ikhadi le-HBA kuma-SATA azimele ama-4 noma ama-SAS hard drive ngaphandle kokudlula ibhanoyi elingemuva.
Uhlobo lwegatsha lokuhlehla (i-SFF-8087 ukuya ku-SFF-8643): Isetshenziselwa ukuxhuma amakhadi amadala e-HBA anezixhumanisi ezibuyekeziwe (ezifana ne-SFF-8643) kubhanoyi yangemuva noma ama-hard drive.
Umehluko obalulekile ukusuka kukhebuli engu-8087 kuye ku-8654:
Inkambu yesicelo: I-MINI SAS 8087 Cable isetshenziswa kakhulu ku-chassis yeseva; kuyilapho i-8087 kuya ku-8654 Cable isetshenziswa ngokuqondile ukuxhuma amadivayisi angaphakathi nangaphandle.
Ukuma komsebenzi: Eyokuqala ikhebula "yokuxhuma kwangaphakathi", kanti eyokugcina kuyikhebula "yebhuloho elingaphakathi nangaphandle".
IV. Isifinyezo kanye Neziphakamiso Zokuthenga
Faka i-MINI SAS 8087 ukuya ku-8654 4i Cable General MINI SAS 8087 Cable
Inhlanganisela yesixhumi esibonakalayo Isiphetho esisodwa SFF-8087, isiphetho esisodwa SFF-8654 Imvamisa zombili iziphetho ziyi-SFF-8087, noma isiphetho esisodwa siphumile
Ukusetshenziswa okuyinhloko Ukuxhuma amakhabethe okwandisa isitoreji sangaphakathi nangaphandle seseva Uxhumano lwengxenye ngaphakathi kwamaseva namadivayisi okulondoloza
Izimo zohlelo lokusebenza I-DAS yangaphandle (Isitoreji Esinamathiselwe Ngokuqondile) uxhumano Ukuxhuma ikhadi le-HBA kundiza engemuva, noma ukuxhuma ngokuqondile ama-hard drive
Uhlobo lwekhebula Ikhebula yangaphandle (imvamisa ijiyile, ivikela kangcono) Ikhebula yangaphakathi
Iziphakamiso zokuthenga: Cacisa izidingo: Ingabe udinga ukuxhuma amadivaysi angaphandle noma wenze izintambo zangaphakathi?
Qinisekisa izindawo zokusebenzelana: Ngaphambi kokuthenga, sicela uhlole ngokucophelela izinhlobo zesixhumi esibonakalayo ekhadini lakho leseva le-HBA nekhabhinethi yokunweba. Thola ukuthi i-SFF-8087 noma i-SFF-8654.
Naka izinguqulo: Qinisekisa ukuthi izintambo zisekela ijubane le-SAS olidingayo (njenge-SAS 3.0 12Gbps). Izintambo zekhwalithi ephezulu zingaqinisekisa ubuqotho besignali nokuzinza.
Ubude obufanele: Khetha ubude obufanele bezintambo ngokusekelwe kusakhiwo sekhabhinethi ukuze ugweme ukuba mfushane kakhulu ekuxhumekeni noma ubude kakhulu ukuze ubangele ukuphazamiseka.
Ngokuhlaziya okungenhla, sikholwa ukuthi unokuqonda okucacile kwe-"MINI SAS 8087 kuya ku-8654 4i Cable" kanye "nekhebula le-MINI SAS 8087". "Ziyizitsha" ezibalulekile ekwakheni uhlelo lokugcina olusebenzayo noluthembekile. Ukukhetha okulungile nokusetshenziswa kwazo kuyisisekelo sokuqinisekisa ukusebenza okuzinzile kwesistimu.
