Ukubuka Konke Kwekhebula le-SAS Kusukela Ekuxhumekeni Kwangaphakathi 8087 Kuya Ku-External High-Speed 8654
Lapho sakha noma sithuthukisa izinhlelo zokugcina izinto ezingeni lebhizinisi, izindawo zokusebenza ezisebenza kahle kakhulu, noma ngisho namadivayisi athile e-NAS, sivame ukuhlangana nezintambo ezahlukahlukene ezibukeka zifana. Phakathi kwazo, izintambo ezihlobene ne-"MINI SAS" zibalulekile kodwa zingadida. Namuhla, sizohlola "Ikhebula le-MINI SAS 8087 kuya ku-8654 4i"futhi"Ikhebula le-MINI SAS 8087"ukukusiza uqonde ngokucacile ukusetshenziswa kwazo kanye nomehluko wazo."
I. Ukuqonda Okuyisisekelo: Kuyini i-MINI SAS?
Okokuqala, i-SAS (Serial Attached SCSI) iyiphrothokholi esetshenziselwa ukuxhuma nokulawula amadivayisi angaphandle ekhompyutha, ikakhulukazi ama-hard disk drive. Ithathe indawo yobuchwepheshe be-SCSI obuhambisanayo obuphelelwe yisikhathi. I-MINI SAS iwuhlobo olubonakalayo lwesixhumi esibonakalayo se-SAS, esincane kunezixhumi zangaphambili ze-SAS futhi singanikeza ukuxhumana kwe-bandwidth ephezulu ezindaweni ezilinganiselwe.
Ngesikhathi sokuvela kwe-MINI SAS, kuye kwavela amamodeli ahlukahlukene esixhumi esibonakalayo, phakathi kwawo i-SFF-8087 kanye ne-SFF-8654 zingabameleli ababili ababaluleke kakhulu.
I-MINI SAS 8087 (SFF-8087): Lena imodeli yakudala yesixhumi sangaphakathi se-MINI SAS. Kuyisixhumi esibonakalayo esinamaphini angu-36, esivame ukusetshenziselwa ukuxhuma i-motherboard (ikhadi le-HBA) ku-backplane noma ngqo kuma-hard drive amaningi. Isixhumi esibonakalayo esisodwa se-SFF-8087 sihlanganisa iziteshi ezine ze-SAS, ngasinye sinomkhawulokudonsa we-6Gbps (kuye ngokuthi inguqulo ye-SAS, ingaba yi-3Gbps noma i-12Gbps), ngakho-ke umkhawulokudonsa ophelele ungafinyelela ku-24Gbps.
I-MINI SAS 8654 (SFF-8654): Lena indinganiso entsha yokuxhuma yangaphandle, evame ukubizwa ngokuthi i-Mini SAS HD. Iphinde ibe namaphini angu-36 kodwa incane ngokomzimba futhi incane kakhulu ngokwakhiwa. Isetshenziswa kakhulu ukuxhuma amachweba angaphandle amadivayisi, njengokusuka ku-server host kuya kukhabhinethi yediski yangaphandle. I-interface eyodwa ye-SFF-8654 isekela neziteshi ezine ze-SAS futhi iyahambisana ne-SAS 3.0 (12Gbps) nezinguqulo eziphakeme.
II. Ukuhlaziywa Okuyinhloko: Ikhebula le-MINI SAS 8087 kuya ku-8654 4i
Manje, ake sigxile egameni elingukhiye lokuqala:Ikhebula le-MINI SAS 8087 kuya ku-8654 4i.
Kusukela egameni, singalichaza ngokuqondile:
Uhlangothi olulodwa yi-interface ye-SFF-8087 (interface yangaphakathi)
Esinye isiphetho yi-interface ye-SFF-8654 (isikhombikubona sangaphandle)
I-"4i" ivame ukumelela "iziteshi ezi-4 ngaphakathi", lapha ingaqondwa njengoba le khebula linoxhumano oluphelele lwe-SAS oluneziteshi ezi-4.
Uyini umsebenzi oyinhloko wale khebula? - "Ibhuloho" elixhumanisa isitoreji sokunwebeka sangaphakathi nesangaphandle seseva.
Izimo ezijwayelekile zohlelo lokusebenza:
Cabanga ukuthi uneseva yombhoshongo noma indawo yokusebenza enekhadi le-HBA ebhodini lomama elinesixhumi esibonakalayo se-SFF-8087. Manje, udinga ukuxhuma ikhabhinethi ye-SAS disk array yangaphandle, futhi isixhumi esibonakalayo sangaphandle sale khabhinethi ye-disk array siyi-SFF-8654 ncamashi.
Ngalesi sikhathi, iIkhebula le-MINI SAS 8087 kuya ku-8654 4iKusebenza. Ufaka ukuphela kwe-SFF-8087 ekhadini le-HBA langaphakathi leseva, bese uxhuma ukuphela kwe-SFF-8654 echwebeni yekhabhinethi yediski yangaphandle. Ngale ndlela, iseva ingabona futhi iphathe wonke ama-hard drive kukhabhinethi yediski.
Kalula nje, lokhu kuyindlela yokuxhumanisa "esuka ngaphakathi iye ngaphandle", efinyelela ukudluliselwa kwedatha okushelelayo nokusheshayo kusuka kusilawuli se-SAS ngaphakathi kweseva kuya kudivayisi yokugcina yangaphandle.
III. Ukuqonda Okuqhathanisayo:Ikhebula le-MINI SAS 8087
Igama lesibili elingukhiye elithi "MINI SAS 8087 Cable" liwumqondo obanzi, obhekisela kukhebula elinesiphetho esisodwa noma zombili eziyi-interface ze-SFF-8087. Ngokuvamile lisetshenziselwa ukuxhumana kwangaphakathi kwamadivayisi.
Izinhlobo ezivamile zekhebula le-MINI SAS 8087 zifaka:
Uhlobo lokuxhumana ngqo (SFF-8087 kuya ku-SFF-8087): Uhlobo oluvame kakhulu, olusetshenziselwa ukuxhumana ngqo phakathi kwekhadi le-HBA kanye ne-backplane yeseva.
Uhlobo lwegatsha (i-SFF-8087 kuya ku-4x SATA/SAS): Uhlangothi olulodwa yi-SFF-8087, kanti olunye uhlangothi lusakazeka lube yizixhumi zedatha ze-SATA noma ze-SAS ezizimele ezine. Le khebula ivame ukusetshenziselwa ukuxhuma ikhadi le-HBA ngqo kuma-hard drive e-SATA noma e-SAS ezizimele ezine ngaphandle kokudlula e-backplane.
Uhlobo lwegatsha elibuyela emuva (SFF-8087 kuya ku-SFF-8643): Lusetshenziswa ukuxhuma amakhadi amadala ajwayelekile e-HBA anezixhumi ezibuyekeziwe (njenge-SFF-8643) kuma-backplane noma kuma-hard drive.
Umehluko obalulekile kusukela kukhebula lika-8087 kuya ku-8654:
Inkambu Yokusebenza: Ikhebula le-MINI SAS 8087 lisetshenziswa kakhulu ku-chassis yeseva; kuyilapho Ikhebula le-8087 kuya ku-8654 lisetshenziswa ngqo ukuxhuma amadivayisi angaphakathi nangaphandle.
Indawo yokusebenza: Eyokuqala yikhebula "lokuxhumana kwangaphakathi", kanti eyesibili yikhebula "lebhuloho langaphakathi-ngaphandle".
IV. Isifinyezo kanye neziphakamiso zokuthenga
Isici Ikhebula le-MINI SAS 8087 kuya ku-8654 4i Ikhebula elijwayelekile le-MINI SAS 8087
Inhlanganisela yesixhumi Isiphetho esisodwa i-SFF-8087, isiphetho esisodwa i-SFF-8654 Ngokuvamile zombili iziphetho ziyi-SFF-8087, noma isiphetho esisodwa siphuma amagatsha
Ukusetshenziswa okuyinhloko Ukuxhuma amakhabethe okwandisa isitoreji sangaphakathi nangaphandle seseva Uxhumano lwengxenye ngaphakathi kwamaseva namadivayisi okugcina
Izimo zohlelo lokusebenza Uxhumano lwe-DAS yangaphandle (Isitoreji Esinamathiselwe Ngokuqondile) Ukuxhuma ikhadi le-HBA ku-backplane, noma ukuxhuma ngqo ama-hard drive
Uhlobo lwekhebula Ikhebula langaphandle (ngokuvamile lijiyile, livikela kangcono) Ikhebula langaphakathi
Iziphakamiso zokuthenga: Cacisa izidingo: Ingabe udinga ukuxhuma amadivayisi angaphandle noma nje ukwenza izintambo zangaphakathi?
Qinisekisa ama-interface: Ngaphambi kokuthenga, sicela uhlole ngokucophelela izinhlobo ze-interface ekhadini lakho le-HBA leseva kanye nekhabhinethi yokunweba. Nquma ukuthi ngabe yi-SFF-8087 noma i-SFF-8654.
Naka izinguqulo: Qinisekisa ukuthi izintambo zisekela isivinini se-SAS osidingayo (njenge-SAS 3.0 12Gbps). Izintambo zekhwalithi ephezulu zingaqinisekisa ubuqotho besiginali kanye nokuqina.
Ubude obufanele: Khetha ubude obufanele bezintambo ngokusekelwe kusakhiwo sekhabhinethi ukuze ugweme ukuba bufushane kakhulu ukuthi bungaxhunywa noma bube bude kakhulu ukuthi bungadala ukuphazamiseka.
Ngokuhlaziywa okungenhla, sikholwa ukuthi unokuqonda okucacile "kwe-MINI SAS 8087 kuya ku-8654 4i Cable" kanye "ne-MINI SAS 8087 Cable". Ziyi "mikhumbi" ebalulekile ekwakheni uhlelo lokugcina olusebenzayo noluthembekile. Ukukhetha nokusebenzisa kahle kwazo kuyisisekelo sokuqinisekisa ukusebenza okuzinzile kwesistimu.
